Liu, 2007 [28]3YesAcupotomyAcupuncture (3 studies)*Cure, markedly effective, effective, ineffectiveAll trials did not mention whether adverse events have occurredThere are some defects in clinical study on the treatment for CR by acupotomy; treatment for CR by acupotomy is safe and efficient treatment for CR, but the bad quality of articles and the deficiency of methodological decline the efficacy and the reliability

One trial reported the adverse reaction, including mild pain and bleedingAcupuncture treatment is effective for CR and is superior to traction in the aspects of effective rate and pain alleviating. The curative effect of traction treatment could be improved when combining with acupuncture. However, the conclusion was uncertain because the quality of enrolled papers was partly low

the mild adverse reaction
Manipulation or massage treatment on CR is safe, effective and both cure rate and the effective rate are much better than other therapies; but due to the limited number of documents included and the quality being not very high, the conclusion is still uncertain

*Cure, markedly effective, effective, ineffectiveTwo trials reported the safety, but no adverse reactions were observedAcupuncture was safe in the treatment of CR. Acupuncture showed better clinical effect than traction therapy. In addition, acupuncture had better analgesic effect and could reduce recurrence. Therefore, acupuncture is probably superior to traction therapy in the treatment of CR, which is not definite due to relatively low level of evidence

Three studies reported the adverse reactions. Only one study described that skin allergy reaction occurred in seven patients after the plaster therapySingle-application of manipulation or massage was superior to traction group and medicine group in effective rate, while no significant differences were noted between the manipulation or massage group and other control groups. In the trials of comparison between union-application of manipulation or massage and other treatments, only manipulation plus acupuncture versus acupuncture group was not significantly different. However, the conclusion is uncertain because the quality of enrolled papers is partly low

To compare Jingfukang granules with western medicine, there was no significant advantage. So Jingfukang granule was effective in the treatment of CR. However, the evidence is insufficient to determine the effect of Jingfukang granules

Fourteen trials mentioned whether adverse events have occurred. Only one trial showed that ten patients presented red mark left on the cervical skin and the pain getting worse after massageManipulation or massage has advantages in treating CR with respect to short-term therapy, pain relief and the signs/symptoms amelioration compared with cervical traction. Manipulation or massage is of higher security. Nevertheless, the wide variety of therapeutic manipulation or massage techniques, diagnosis, and treatment standards is inconsistent

Zhu, 2015 [35]3YesCervical spine manipulationCCT (3 studies)*VASOne out of three trials reported the adverse events and none with a small sample sizeThere was moderate level evidence to support the immediate effect of cervical manipulation in treating CR. However, the safety of cervical manipulation cannot be taken as an exact conclusion

*Definition of “cure,” “markedly effective,” “effective,” and “ineffective,” cured: clinical symptoms resolved, the cervical or limb functions restored to normal.
Markedly effective: clinical symptoms significantly alleviated, cervical and limb functions effective.
Effective: clinical symptoms alleviated, but cervical or limb functions remain impaired. Ineffective: clinical symptoms and signs remain unchanged after the treatment.
*MPQ: McGill pain questionnaire; *VAS: visual analogue scale; *TCSSG: total clinical symptoms and signs grading.
CR: cervical radiculopathy; CCT: cervical computer traction; TDP: special electromagnetic therapeutic apparatus; IFTA: intermediate-frequency therapy apparatus.
TCM: traditional Chinese medicine; VCDI: vertebral canal drug injection; TCMI: traditional Chinese medicine injection; EH: electromagnetic heating.
