Early Intervention with a Parent-Delivered Massage Protocol Directed at Tactile Abnormalities Decreases Severity of Autism and Improves Child-to-Parent Interactions: A Replication Study
Tactile abnormalities are severe and universal in preschool children with autism. They respond well to treatment with a daily massage protocol directed at tactile abnormalities (QST massage for autism). Treatment is based on a model for autism proposing that tactile impairment poses a barrier to development. Two previous randomized controlled trials evaluating five months of massage treatment reported improvement of behavior, social/communication skills, and tactile and other sensory symptoms. This is the first report from a two-year replication study evaluating the protocol in 103 preschool children with autism. Parents gave daily treatment; trained staff gave weekly treatment and parent support. Five-month outcomes replicated earlier studies and showed normalization of receptive language (18%, ), autistic behavior (32%, ), total sensory abnormalities (38%, ), tactile abnormalities (49%, ), and decreased autism severity (medium to large effect size, ). In addition, parents reported improved child-to-parent interactions, bonding, and decreased parenting stress (44%, ). Early childhood special education programs are tasked with addressing sensory abnormalities and engaging parents in effective home programs. Until now, they have lacked research-based methods to do so. This program fulfills the need. It is recommended to parents and ECSE programs (ages 3–5) at autism diagnosis.
Autism spectrum disorder (ASD) is the most rapidly growing childhood developmental disability in the United States . Currently, it is estimated to affect one in 68 children . To date, there is no known cause, no known cure, and no known explanation for why symptoms emerge prior to the age of two. In 2013, the diagnostic criteria for ASD were updated and abnormal sensory responses were included . Today, ASD is diagnosed by a dyad of persistent symptoms that arise before the age of two: deficits of social interaction and restricted, repetitive behaviors, including sensory abnormalities. Symptoms occur on a spectrum of severity that is characterized on the basis of communication deficits and inflexibility of behavior.
Abnormal sensory responses were included in the diagnostic criteria for autism in 2013 because there was mounting evidence that they are directly related to severity of autism . They occur early in life, encompass a range of hypo- and hyperreactivity, and are highly prevalent in children with autism . Since early in the research literature, abnormal sensory responses have been widely thought to be due to disordered processing of sensory information [6–10]. Of all the sensory abnormalities, abnormal tactile responses are the most prevalent, with reported rates over 95% by parent report and direct observation [11, 12]. They are described in terms that are remarkably severe and unusual  but have never been subjected to full neurological evaluation.
The neurological evaluation of tactile symptoms proceeds by evaluating sensory nerve function relative to touch, pain, temperature, vibration, and position in symptomatic areas and then ruling out central pathology . Ruling out peripheral sensory impairment is done first because sensory loss early in development results in both disordered sensory processing and changes in brain structure [15, 16]. Surprisingly enough, this evaluative sequence has not been followed in autism, and to date only three small studies evaluating partial aspects of touch have been published [17–19]. As such, a primary impairment of touch has not been ruled out, and a full neurological evaluation of the sense of touch has been urgently called for . The missing information is extraordinarily germane because touch is the primary sense informing the bonding and preverbal communication that is required for social and language development [21, 22], and impairment of the sense of touch early in development can readily account for the social/language delay and disordered sensory processing that has been so well documented in autism.
Over the course of 14 years and 10 peer-reviewed research studies, our research group has investigated a model and treatment for autism proposing that autism symptoms are due in some part to tactile impairment [12, 23–27] and are treatable with a massage protocol based on Chinese medicine. Loss/damage to the sense of touch is proposed to block the child’s perception of soothing and affectionate parent touch and interfere with social/language and self-regulatory development. This can first be observed when soothing touch fails to soothe the child, and affectionate touch fails to stimulate the social response, simultaneous orienting, eye contact, and listening . The tactile barrier to soothing is proposed to result in prolonged episodes of elevated sympathetic tone [29, 30] and account for the remaining sensory abnormalities on the basis of poorly regulated sympathetic tone disorganizing sensory thresholds [31, 32].
For the purposes of our research we developed a checklist of common sensory symptoms in children with autism that could be used to identify skin areas in need of massage treatment and to measure tactile and other sensory outcomes . The checklist also identifies delays of early touch-stimulated self-regulation milestones, including self-soothing, attention, sleep, digestion, and behavioral self-regulation . The validation study distinguished children with autism from typical and otherwise developmentally delayed groups by a multifocal tactile abnormality characterized by signs of painful withdrawal from noninjurious touch (allodynia/pain) and lack of response to injury (hypoesthesia/numbness) . Ninety-three percent of the ASD group had signs of pain with touch on the face and in the mouth, 93% on the scalp, and 88% on the fingers and toes. Sixty-five percent had signs of numbness in response to injury. In addition, there was global delay of first-year self-regulation milestones. Pain and numbness are typical of the clinical presentation of small fiber neuropathy, a common disorder of small sensory fibers in the skin .
Experimental data from two randomized controlled trials (RCT) evaluating five months of daily massage treatment support our model for autism [24, 25]. The protocol is called Qigong Sensory Treatment (QST) massage for autism. The protocol is designed to increase circulation to the skin, normalize the child’s perception of touch, and allow touch-stimulated social and self-regulatory development to unfold naturally in the context of the care and feeding of the child. The outcomes of the two studies, one evaluating a program of five months of dual parent- and therapist-delivered treatment (, QST Dual program) and the other evaluating the parent component (, QST Home program), showed increased social and self-regulatory abilities, reduced autistic behavior, and reduced tactile and other sensory symptoms. The intervention was effective in both high- and low-functioning children and ten-month follow-up indicated that continued treatment resulted in continued improvement . Longer-term studies to determine the endpoint of treatment have not yet been conducted.
From the start of the research, it was evident that treatment outcomes were highly dependent on parent fidelity with daily treatment. However, children’s initial resistance to touch, the range of tactile responses seen, the complexity of adjusting treatment to changing responses, and the need for long-term daily treatment called for a manual with flexible procedures and a program of ongoing parent training and support. Thus a five-month parent training program was developed, comprised of a parent handbook  and an initial 3-hour training, followed by 20 one-on-one support visits with a trained professional. This proved to be adequate to ensure fidelity with the intervention in the first five months of treatment.
The present study is part of a three-year, multisite RCT replicating and extending previous studies and evaluating the efficacy of the QST Dual massage intervention on tactile abnormalities and severity of autism in a larger group. In the first two years, treatment outcomes for 103 children under the age of six will be evaluated. In year three, treatment outcomes for 35 children between the ages of 6–11 will be evaluated. We will also seek further evaluation of tactile abnormalities with skin biopsy.
The three-year study will test two hypotheses.(1)Treatment of 103 preschool children with autism with the QST Dual massage intervention will result in decreased severity of autism across language, behavioral, and other sensory aspects of autism compared to the control condition. Treatment will be effective in both lower- and higher-functioning children. In addition, treatment will improve tactile and other sensory abnormalities and early self-regulation milestones and reduce parenting stress.(2)Treatment outcomes will be independent of severity of autism.
The objectives of this portion of the study are to evaluate initial 5-month treatment outcomes on severity of autism and on parent-child interaction and bonding. As compared to previous studies, this study will add new measures evaluating the overall severity of autism and receptive/expressive language level, as well as qualitative analysis of parent comments on parent-child bonding and interactions. The main outcomes are on measures of severity of autism, autistic behavior, and language development. The secondary outcomes are tactile and other sensory abnormalities, self-regulatory delay, parenting stress, and general development. In addition, qualitative data on parent comments will be presented and analyzed.
2. Materials and Methods
2.1. Study Design
This study was a multisite, randomized, single-blind, controlled trial of the QST Dual massage intervention in 103 preschool children with autism. Blinded professional examiners evaluated baseline and interval measurements. Baseline and interval reports were collected from parents. This is a replication and extension study of previously published studies; therefore, it was not possible for parents to remain blind to group. However, parents are known to be accurate reporters of current, observable child behavior  and parent information was treated as reliable and accurate. Children were randomized to treatment and control groups using a random number generator. Both groups were enrolled in early intervention programs. The treatment group received five months of daily parent-delivered massage and 20 sessions of therapist-delivered massage. Fidelity was assured with a formalized training program and ongoing support. The control group was in the waitlist condition and received treatment after five months. Treatment was directed towards normalizing responses to touch. Pre- and posttesting were done by the same professional examiners who were blind to group. Additional data was collected from parents. The study was conducted with Institutional Review Board approval and registered with the U.S. National Institutes of Health clinical trials registry (# NCT01801696).
2.2. Participants and Recruitment
Recruitment was accomplished via distribution of brochures, emails, listserv messages, website postings, presentations, social media, TV, radio, and word of mouth. In addition, invitation letters were sent to parents of children aged 2 to 5 receiving autism services from state-funded, early childhood special education and early intervention programs in eight counties in Oregon. Criteria for entry into the study included age of 2 to 5 years; diagnosis of autism; no additional chronic disability; no psychoactive medication or pharmaceutical chelation therapy; and not receiving more than fifteen hours per week of intensive behavioral treatment for autism. This criterion was chosen because there is no research evidence that low-intensity ABA treatment produces therapeutic outcomes [38, 39]. Only two study participants were identified as receiving ABA treatment; they were receiving 8 and 10 hours/week, respectively. Parents agreed to give their children the daily massage treatment for the duration of the study; to follow through with all training and support visits; and not to begin additional interventions for autism during the study. Parents provided records documenting their child’s autism diagnosis. The majority of diagnoses had been previously made at autism evaluation centers using instruments such as the ADI and/or the ADOS. Children subsequently underwent a second diagnosis with such instruments prior to acceptance into early intervention autism programs. Prior to acceptance into the study, records were reviewed and the previous diagnosis of autism was confirmed. In addition, a developmental pediatrician reviewed the pretreatment testing and reconfirmed the autism diagnosis using DSM-IV criteria.
2.3. Study Completion
Figure 1 provides an overview of participant flow. One hundred thirty-six children were screened for the study during the period of September 2012 through April 2014 by the principal investigator and the project director. An additional 39 parents indicated interest in enrolling their children but did not submit enrollment documents. One hundred three children from 10 different counties in Oregon were determined to be eligible for the study, of which 55 were randomized to the treatment group and 48 to the waitlist control group. During the study period, 19 participants withdrew from the study for a total participant completion rate of 82% and a final for both study and control groups.
2.4. Randomization Procedures
Children and their families from each geographical area who met study criteria were randomly assigned into either the treatment or control group condition based on age in months to reduce bias on developmental measures. A random number generator was used. One pair of siblings was assigned into the same group by necessity. Odd numbers of participants in each site resulted in uneven initial group sizes when randomized.
2.5. The Massage Protocol
The QST massage protocol is a whole-body massage that takes about 15 minutes to give and is usually done at bedtime. It is formalized in a parent training handbook with flexible constraints . The parent does not avoid areas that are uncomfortable but instead works with them by attuning the massage techniques to the child’s responses, within the comfort zone of the child. Over the course of treatment, tactile responses undergo predictable changes from hyposensitive to hypersensitive to normosensitive . The protocol requires adjustment of the manual technique with each transition. The protocol also aims to sequentially stimulate social and self-regulatory activity, first by stimulating awareness and receptivity to massage, then by stimulating eye contact and smile, and finally by stimulating deep relaxation with touch.
The protocol has 12 parts that follow the acupuncture channels down the front and back of the body. Massage is carried out in a downward direction towards the hands and feet in the direction of capillary blood flow. Both patting and pressure are used according to the child’s response. Generally, a quicker, lighter, patting technique is used to begin with, but in areas where the child withdraws from touch or is ticklish, slower pressing techniques are used. Additional options are available when neither patting nor pressure resolves the difficulty. For a summary of the massage movements, go to http://qsti.org/wp-content/uploads/2014/06/12MovementsAutism.pdf.
Therapists providing the parent training and support program benefitted from a 60-hour training. A total of 19 therapists participated in the study. Parent training unfolded with a group training followed by weekly one-on-one support. At each visit, therapists inquired about fidelity with daily massage, provided ongoing support and training, and gave children a massage treatment.
There are four time periods when parents are at risk for discontinuing the program. These are (1) upon initiating the program and not knowing how to deal with the child’s resistance to massage; (2) during the transition period when the sensory system switches from hyposensitive to hypersensitive and massage techniques must be modified; (3) the transition period when the child moves into the autonomy phase of development and parenting techniques must be modified; and (4) the period after which the child has come to relax and enjoy the massage, progress is no longer dramatic, and daily massage can fall off the priority list. Therapists were instructed to watch for these at-risk periods and provide the necessary support.
Demographic information was obtained from participants and is shown in Table 1. Treatment and control groups were comparable. Overall, the percentage of boys (89%) was higher than the national average. Lower income families were identified as being at or below 100% and 150% of federal poverty guidelines for 2014 . Representation of lower income families (53%) and culturally diverse families (44%) was higher than state demographics (Hispanic 34%, American Indian/Alaska Native 7%, and Native Hawaiian/Pacific Islander 3%). Eighty percent of parents involved had no previous experience with massage or Chinese medicine. Families who withdrew from the study did not have different demographics.

Note: parents could select more than one ethnicity/race. So the numbers add up to more than the number of subjects.
The following measures were used to evaluate five-month treatment outcomes.
(1) Childhood Autism Rating Scale, 2nd Edition, Standard Version (CARS2-ST) . The CARS2 standard version is validated for children younger than 6. It has been found to be stable in the face of change over 12 months and not generally used as an outcomes measure. Total CARS scores range from 15 to 60. A score of 30 serves as the cutoff for a diagnosis of autism on the mild end of the autism spectrum; 30 to 36 is scored as mild to moderate; 36 and higher is scored as severe. The pretreatment median score of 39 was used as the criteria in the analyses to determine effects on language development by level of severity. Internal consistency is reported at .93, interrater correlation at .95, and test-retest stability at .88. The CARS2-ST was administered by professionals who were blind to group.
(2) Preschool Language Scale, 5th Edition (PLS-5) . The PLS-5 has standardized subscales which evaluate relative ability in receptive and expressive language in children under 7. The test-retest stability coefficients ranged between .97 and .98 for the subscale scores and .97 to .98 for the total score. Internal consistency (split-half reliability) ranges from .91 to .93 for the subscale scores and .95 for the total score. The PLS-5 was administered by blinded professionals.
(3) Vineland Adaptive Behavior Scales, 2nd Edition (Vineland-II) . The Vineland-II is a validated parent interview that assesses socialization, communication, motor skills, and daily living skills. Internal consistency split-half reliability coefficients were .97 for the composite scale and ranged from .83 to .95 for the domains. Test-retest coefficients were .94 for the composite scale and ranged from .88 to .92 for the domains. Raw scores were used in the statistical analysis while age equivalent scores are used to illustrate the magnitude of the changes in development over the treatment period. The social and daily living subscales were administered by blinded professionals.
(4) Autism Behavior Checklist (ABC) . The ABC is a validated measure of autism and a component of the Autism Screening Instrument for Educational Planning. The ABC is used as a measure of change in response to the classroom program and as an outcomes measure in research. It measures behaviors typical of autism in five domains: sensory, relating, body and object use, language, and social and self-help. Adequate reliability and an alpha coefficient of .89 are established. Parents completed the ABC to report outcomes in the home setting at baseline and 5 months. The mean value for typically developing children is reported at 17.81 .
(Note: we were particularly interested to see whether we could replicate previous results in individuals with low functioning autism as there is little available evidence-based treatment for that group. Thus, we used two outcomes measures of autism severity: the CARS, a highly stable measure that is stable over a 12-month interval, and the ABC, a more sensitive questionnaire that is currently used in conjunction with a direct observation measure for evaluating educational outcomes . Both the CARS and the ABC measure current functioning relative to similar aspects of autism but differ as to the length of time over which the measurement is taken. One is a direct-observer measure taken at a single point in time; the second is a questionnaire that solicits information describing the child at the present time. Thus, because child behavior can differ from day to day, measures were analyzed together in order to get a more balanced view of present functioning.)
(5) Sense and Self-Regulation Checklist (SSC) . The SSC is a validated parent/caregiver measure of sensory difficulties and self-regulatory delays in children with autism under the age of 6. It is used as an outcomes measure in clinical practice and research. Scores can be generated for sensory and self-regulation domains. An overall internal consistency alpha of .87 has been demonstrated. Sensory items have an internal consistency alpha of .83; self-regulation items have an internal consistency alpha of .78. The SSC significantly differentiates children with autism from otherwise developmentally delayed (other DD) and typically developing (typical) children. The means and standard deviations for abnormal sensory response for ASD, other DD, and typically developing children are 39.6 (SD 10.6), 30.6 (SD 7.9), and 18.4 (SD 9.5), respectively. The mean oral/tactile scores for ASD, other DD, and typical children are 29.2 (SD 7.9), 22.8 (SD 6.7), and 13.5 (SD 7.2), respectively. The mean self-regulatory difficulty scores for ASD, other DD, and typical children are 56.8 (SD 14.1), 44.0 (SD 13.4), and 25.8 (SD 11.3), respectively. The SSC was completed by parents and used in data exploration of intervening variables affecting treatment outcomes.
(6) Autism Parenting Stress Index (APSI) . The APSI is a validated parent/caregiver measure of parenting stress relative to autism symptoms. It is intended to measure the level of difficulty experienced by parents in successfully parenting the various physical and behavioral manifestations of autism, as well as factors impacting parenting stress such as lack of feeling close to the child, and concerns about the future of the child. It is used as an outcomes measure in clinical practice and research. Current data indicate adequate internal consistency (.83) and test-retest stability (.89). A validation study comparing scores from children with ASD with normally developing and otherwise developmentally delayed peers showed that the scales differentiate significantly between groups, with mean scores for ASD, other DD, and typical children of 23 (SD 10.4), 11.74 (SD 6.7), and 5.4 (SD 5.1), respectively. The APSI was completed by parents and used to measure changes in parenting stress relative to autism symptoms.
(7) Beach Center Family-Professional Partnership Scale . The partnership scale is a validated tool that assesses satisfaction with services received. It contains two subscales: child-focused relationships and family-focused relationships. This 27-item scale is designed to be used as a research tool. Cronbach’s alpha is 0.93. Parents completed the partnership scale at posttesting.
(8) Fidelity and Social Validation Testing. Therapists monitored parent fidelity with massage procedures by testing parents at weeks one and two with a checklist. The principal investigator monitored therapist fidelity with the parent training and support program. Parents completed a daily log recording fidelity with daily massage, reasons for missing the massage, and problems or concerns. In addition, parents completed a posttreatment survey consisting of a series of open-ended questions exploring their reactions to treatment and outcomes. See Table 2 for posttreatment survey questions.
2.7. Data Collection
Pre- and postintervention data collection was conducted within a one-month window both prior to beginning of treatment and after the 20-week intervention for children in both the treatment and control conditions. Parents completed an online set of surveys and background questionnaires that included the Autism Parenting Stress Index, the Sense and Self-Regulation Checklist, and the Autism Behavior Checklist. The Vineland-II, CARS2-ST, and PLS-5 were administered in the home by trained, blind-to-condition professionals. Treatment fidelity was monitored throughout the 20-week intervention by assigned therapists.
2.8. Data Analysis
Initial analyses were conducted to detect any potential attrition bias using 2-way ANOVA and MANOVA on preassessment outcome measures. This was followed with analyses to confirm equivalence of treatment and control groups on preassessment outcome measures using 2-way ANOVA and MANOVA. Descriptive and paired -tests on outcome measures were conducted for both treatment and control groups. Main treatment effects were tested using 2-way repeated measure ANOVAs and MANOVAs. Testing whether treatment outcomes were independent of language ability and severity of autism was also conducted using 2-way repeated measure ANOVAs and MANOVAs.
3.1. Sample Size Justification and Power Analysis
A power analysis to determine sample size for this study was conducted using pooled data from all children under the age of six who had participated in our previous studies and received the QST intervention. The primary outcome used was the composite score from the Pervasive Developmental Disorders Behavior Inventory . An of 45 for both the treatment and control group, with 12% attrition, yielded a final of 40 for each group. Allowing for attrition, a final of 40 in each group, and a , a power analysis yielded a power of .99 on parent measures.
3.2. Potential Attrition Bias
Participants in the control and treatment condition withdrew at a proportional rate , . Two-way ANOVA and MANOVA indicate no differences between completers and noncompleters on outcome measures. values range from .018 to 3.57 with associated values ranging from .894 to .062. There was a difference in age between completers and noncompleters, with noncompleters being on average six months younger than completers , .
3.3. Equivalence of Treatment and Control Groups
Participants in the treatment and control conditions did not differ on outcome measures or age. Two-way ANOVA and MANOVA indicate no differences between groups on outcome measures and age. values ranged from .619 to 1.56 with associated values ranging from .528 to .216.
3.4. Preassessment to Postassessment Changes
Table 3 displays descriptive pre- and postoutcomes for both treatment and control groups. Paired -test results are also shown. Treatment group participants experienced significant improvement on all measures. Control group participants also experienced significant improvements on a number of measures, although typically these changes were not as large as for the treatment group. Because mean scores for text typically developing children are well above zero, an additional column calculating percent (%) change toward typical norm has been added to Table 3 to show the percent (%) normalization of the reported change. Children in the treatment group experienced a 38% decrease in abnormal sensory response toward normalization. These children experienced a 49% decrease in abnormal oral/tactile response toward normalization. The decrease in self-regulatory difficulties represented 34% improvement toward normalization. Autistic behavior decreased 32% towards normalization. Parents of these children experienced a 44% decrease in stress toward normalization.
|Note: SD = standard deviation; Diff. = the change from pre- to postscore; % norm = the percentage reduction in parenting stress, autistic behavior, abnormal sensory responses, and self-regulatory difficulties toward typically developing children.|
3.5. Intervention Effects on Main and Secondary Outcomes
Main outcomes include severity of autism, language, and general development. Secondary outcomes include sensory, self-regulation, and parenting stress. Table 4 presents results from the 2-way repeated measures ANOVA and MANOVA analyses. Equality of error variances were confirmed for all analyses. There was an overall treatment effect in reducing the overall severity of autism in the treatment group as measured by the CARS and ABC. Effect size was in the medium to large range. Post-hoc univariate analyses found a significant effect on the ABC but not the CARS. The correlation between the ABC and CARS was low (.273), indicating that they measure different things.
Separate 2-way repeated measure ANOVAs were conducted on receptive and expressive language. A significant treatment effect was found on receptive language with an effect size in the medium range. No treatment effect was found on expressive language.
A 2-way repeated measures MANOVA was conducted on general development of social and living skills. No treatment effect was found on general development. Both groups experienced increases in raw scores equivalent to 4–8-month increases in mental age on living skills and 4–6 months on socialization.
A 2-way repeated measures MANOVA was conducted on sensory and self-regulation. An overall significant treatment effect was found with a large effect size. Post-hoc univariate analyses found a significant effect on the sensory abnormalities, tactile/oral abnormalities, and the self-regulatory difficulties.
Finally, a 2-way repeated measure ANOVA was conducted on parenting stress. A significant treatment effect was found with a large effect size.
3.6. Effectiveness of Treatment by Severity of Autism
To further test whether the effectiveness of the treatment was independent of severity of autism, the treatment group was split into mild/moderate (a score of less than 39 on the CARS) and severe (a score of 39 and higher on the CARS) autism subgroups. Paired -tests were performed on the outcome measures for the subgroups.
As can be seen in Table 4, there was an overall significant treatment effect on receptive language. Further, children with both mild/moderate and severe autism experienced significant improvements in receptive language as measured by the PLS-5 Auditory Language ( values are −4.26 and −4.29, respectively, with associated values of .0001 and .0003).
The results in Table 4 show overall significant multivariate and post-hoc univariate treatment effects on abnormal sensory response and self-regulation. Again, children with mild/moderate and severe autism both experienced significant reductions in abnormal sensory response and self-regulatory difficulties as well as tactile/oral abnormalities ( values ranged from −4.24 to –5.88, with respective values ranging from .0004 to .00001).
The overall significant treatment effect on reducing parenting stress is shown in Table 4. Parents of children with mild/moderate and severe autism experienced significant reductions in stress ( values were −5.135 and −4.448, with associated values of .0001 and .0002).
3.7. Parent Satisfaction and Reactions to the Treatment and Outcomes
The Beach Center Family-Partnership Scale survey showed that 95% of the treatment group parents were very satisfied with their experience with the intervention, and 5% were somewhat satisfied.
Table 5 lists examples of parent responses to posttreatment survey questions about the parent experience of changes in their child. The table has additional columns reporting the survey question referenced (see Table 2). The table illustrates the normalization of touch and relationship that all parents experienced in one way or another with their child and gives examples of the accompanying sensory and behavioral changes that they observed.
Table 6 lists the types of responses parents had to posttreatment questions 4 and 5: “When you compare the massage to other treatments, how does it differ?” and “If you could sum up your experience in a way that would be helpful for another parent considering this treatment, what would it be?” Themes that emerged were improved bonding (18), parent empowerment to actively help their child (12), treatment supporting overall development (5), and ability to easily give the treatment at home (3).
Therapists tested parents on the 12 massage movements after the first and second week of treatment using a checklist. At the end of the second week, 75% of parents demonstrated complete fidelity with massage procedures. The other 25% needed correction on one or two of the 12 parts of the massage. For those that did not complete all 12 movements correctly, therapists checked on fidelity each of the following weeks until all 12 movements were correct. Twenty-nine of the 42 sets of parents provided the treatment daily throughout the 5-month treatment period. The balance, 13, provided the treatment less than daily during some periods, usually due to sickness of the child or the parent. All therapists provided 20 training and support visits.
3.9. Adverse Effects
There were no adverse effects reported in children. One parent with severe wartime PTSD found that he was unable to give the massage due to excessive anxiety triggered by his child’s resistance to touch. Once he stopped giving the massage, he experienced no further anxiety relative to the massage.
This is the first evidence-based intervention for tactile abnormalities in children with autism that effectively treats them with a massage protocol rather than making environmental accommodations to them. Before treatment, the mean tactile abnormality score for the treatment group was more than twice that of the typically developing group. After treatment, scores normalized by 49%. Parents reported that the massage helped to build a stronger bond and improved the experience of touch and relationship. Children sought out touch and affection from their parents, and parents felt closer and more connected. Child-to-parent attachment difficulties are described in the autism literature , and the profound degree to which they impact the parenting experience is illustrated in the parent comments, the very large decrease (44%) in parenting stress, and the very high parent satisfaction rate (95%) when they improve. Attachment theory has had difficulty in accounting for attachment difficulties in autism because they exist despite evidence of normal parent-to-child bond and sensitivity . We suggest that normal attachment requires child sensitivity as well and that tactile abnormalities interfere with child-to-parent bonding. The very good news is that tactile abnormalities are reversible with treatment.
We were particularly interested in the 5-month treatment outcomes on receptive language. Concordant with increased diagnosis of high functioning autism (HFA) , this study had a higher proportion of children with HFA than previous studies. In children with low functioning autism (LFA), receptive language delay stands in the way of the development of speech; in children with HFA, receptive language delay manifests as echolalia or as monologues on topics of interest, for example, dinosaurs or robots. As it turned out, receptive language improved in both groups by a mean value of 18%. We ascribe the improvement to the effect of normalization of touch on foundational social and nonverbal communication abilities: the ability to be receptive to another person, make eye contact, give face-to-face attention, and listen. All of these are normally stimulated by touch in the first year of life in typically developing children but tend to be absent in young children with autism.
This was a replication and extension study, a necessary step before an intervention can be more widely recommended. Results replicated earlier studies with regard to overall decrease in severity of autism, improvements in autistic behavior, communication, sensory symptoms, and parenting stress. As shown previously, treatment was effective in both low- and high-functioning children. We were particularly interested to see whether we could replicate previous results in individuals with LFA, as there is little available evidence-based treatment for that group. We used two outcomes measures of autism severity: a highly stable measure that is stable over a 12-month interval (the CARS) and a more sensitive questionnaire currently used in conjunction with a direct observation measure for evaluating educational outcomes (the ABC). Thus it was quite remarkable that the CARS confirmed the findings of the ABC in showing significant decrease in severity of autism in the LFA group over the relatively short treatment period of five months. The CARS did not reflect the improvement seen on the ABC in the HFA group. We think this is most likely because the CARS was not standardized on individuals with HFA, has a compressed range of scores for HFA, and is less sensitive in that group . We await the one- and two-year results to see whether the CARS will confirm the ABC results in the HFA group after a longer intervention period.
Taken altogether, these results represent a breakthrough in autism treatment. It is the first research-based intervention to be effective for the individual sensory, behavioral, and language components of autism as well as severity overall; it is the first intervention to be effective in both lower- and higher-functioning children. And it is the first time a model for autism revolving around tactile abnormalities is presented and supported with experimental data. The intervention was powerfully effective with children, because parent touch is critical to early social and self-regulatory development and because the intervention normalized children’s sense of touch. As a result, behavior improved, social and self-regulatory gaps in the developmental foundation are filled in, and development was better supported.
Early intervention policy is to involve parents of children with autism in the direct care of their child’s disability and offer them training and support in research-based home interventions. Parents desperately need effective tools to help their children. Two parent-delivered interventions are commonly recommended to parents of newly diagnosed children with autism by occupational therapists: the Wilbarger brushing protocol and joint compression [53, 54]. There is little research demonstrating efficacy on autism symptoms for either method. Since there is now replicated research to show efficacy for QST massage for autism, we recommend that parents be offered training and support in QST massage at the time of their children’s autism diagnosis.
Over the past 14 years, our research has been conducted in collaboration with state-sponsored, early intervention programs for autism. School administrators are well aware of the importance of early identification and treatment of hearing and vision impairment to educational outcomes for children. A randomized controlled trial conducted in children with autism in early intervention classrooms has already shown that classroom behavior and social communication skills improved in the classroom with QST massage . As the tactile abnormality in autism comes to be better understood and QST massage comes to be better known, we anticipate that tactile abnormalities will also be recognized as important to educational outcomes and that QST massage will be recommended. In our view, all children with autism should be evaluated for the need for hearing aids, glasses, and QST massage at the time of diagnosis. The results presented here support earlier recommendations to implement the QST program at the time of autism diagnosis concurrent with the early intervention program in order to prepare the child for school. If tactile and other sensory symptoms can be remediated prior to entering school, educational outcomes can only be enhanced.
The QST Dual program for autism directed at tactile abnormalities was effective in decreasing severity of individual sensory, behavioral, and language components of autism as well as severity of autism overall. The intervention works by decreasing tactile and other sensory abnormalities and removing the sensory barriers to learning social/language skills and regulating behavior. Child-to-parent bonding improved, and the experience of touch and relationship normalized for parent and child. Children were better able to make eye contact, focus, and listen, and parenting stress decreased. This program can be recommended to parents and early intervention programs at the time of autism diagnosis. It can be expected to improve educational outcomes for children and reduce stress in the preschool classroom environment.
