Objective To observe therapeutic effect of one-finger scrubbing combined with acupuncture kinesitherapy on stiff neck. Methods One hundred cases of stiff neck were treated with one-finger scrubbing combined with acupuncture kinesitherapy at Houxi (后溪 SI 3) and Shugu (束骨 BL 65) on the affected side, once a day, three clays made one session and totally one session was required. The clinical efficacy was observed. Results Fifty-two cases were cured with one treatment, 32 cases with two treatments and 12 cases with three treatments. Totally 96 cases (96%) were cured, 4 cases (4%) were effective. Conclusion The twining manipulation combined with acupuncture kinesitherapy has obvious therapeutic effect on stiff neck. 展开更多

Objective:To observe the effect of Yi Jin Jing(Sinew-transforming Qigong Exercises)plus tuina on the neck for stiff neck.Methods:A total of 60 patients with stiff neck who met the screening criteria were selected and randomly divided into two groups,with 30 cases in each group.Patients in the control group received tuina on the neck,30 min every time,once a day,while patients in the observation group practiced Yi Jin Jing(Sinew-transforming Qigong Exercises)plus the same tuina therapy as the control group,and Yi Jin Jing(Sinew-transforming Qigong Exercises)was conducted for more than 30 min every time,once a day.Visual analog scale(VAS)scores were observed before treatment,and after 1 time,3 times and 5 times of treatment to evaluate the degree of neck pain.Results:During the treatment,each group had 2 dropouts.After treatment,the total effective rate was 92.9%in the observation group versus 82.1%in the control group,showing a statistical significance(P<0.05).The VAS scores in the observation group at the three time points were significantly lower than those in the control group(all P<0.05).Conclusion:Yi Jin Jing(Sinew-transforming Qigong Exercises)plus tuina on the neck can effectively relieve neck pain and improve cervical range of motion in patients with stiff neck,and can achieve a better effect than tuina alone. 展开更多
