Grossman et al. [29] 2010,
Switzerland | To examine the effects of a mindfulness-based intervention (MBI) compared to usual care upon quality of life, depression, and fatigue among people with MS. | Randomised controlled trial.
Intake interview, 8 weekly 2.5- hour classes, one 7- hour retreat, 40 minutes of homework daily versus usual care (UC) (including medical examination before intervention and six months after intervention). | 150 participants with relapsing-remitting or secondary progressive MS
recruited from outpatient neurology clinic, other physicians, or advertisements in the Swiss Multiple Sclerosis Society Bulletin.
Blinded, randomised group allocation. | Outcomes measured before intervention, after intervention, and at six-month follow-up:
Profile of Health-Related Quality of Life in Chronic Disorders (PQOLC),
Hamburg Quality of Life Questionnaire in Multiple Sclerosis (HAQUAMS),
Center for Epidemiologic Studies Depression Scale (CES-D),
Modified Fatigue Impact Scale (MFIS),
Spielberger Trait Anxiety Inventory (STAI),
Neurologist-administered Neuropsychological assessment,
Researcher-devised assessment of personal goal attainment after MBI, and self-reported homework adherence. | Compared to baseline, at postintervention MBI participants showed significant improvements in PQOLC, HAQUAMS, CES-D, MFIS, and STAI greater than the UC group. The benefits remained at six-month follow-up although the effect was lessened for PQOLC and depressive symptoms.
The outcomes were not related to gender, EDSS, or taking disease modifying drugs. | Control group not offered sham intervention.
Exclusion criteria: other types of MS, Expanded Disability Status Scale score >6 or >1 step increase in previous 12 months, current MS exacerbation, symptomatic medication alteration in previous 3 months, serious psychological disorder or dementia, life threatening or severely disabling physical condition, and others.
5% attrition in intervention group and high attendance rate. |

Mills & Allen [32], 2000,
United Kingdom | To examine whether mindfulness of movement affects balance and change in symptoms (pilot study). | Randomised controlled trial.
Six individual sessions of one-to-one instruction and resources for guidance at home vs. usual care. | 12 intervention participants and 12 control participants
recruited through local physiotherapists and general practitioners. | Outcomes measured before intervention, after intervention, and at three-month follow-up:
Activities of Daily Living questionnaire,
test of balance-timed single leg standing,
symptom rating questionnaire (21 listed symptoms), and
a close relative or friend was also asked to independently assess the degree of change. | The intervention group showed greater likelihood of improvement and less deterioration in symptoms.
Measures of overall symptom change showed significant differences between intervention and control groups after intervention and at 3 months.
The intervention group also showed improvements in balance which were maintained at 3 months. | All patients with secondary progressive MS and inclusion criteria were having at least one symptom which affected their life on an ongoing basis.
Very small sample size
3 dropped out of intervention group and 2 did not return all surveys; 4 did not return all surveys in control group. |
