[Yin-yang balance penetrating acupuncture combined with rehabilitation training on upper limb spasticity in stroke hemiplegia].

OBJECTIVE
To compare the therapeutic effect of yin-yang balance penetrating acupuncture combined with rehabilitation training and single rehabilitation training on upper limb spasticity in patients with stroke hemiplegia.


METHODS
A total of 60 patients with upper limb spasticity of stroke hemiplegia were randomized into an observation group and a control group, 30 cases in each one. On the basis of conventional western medication, rehabilitation training was adopted in the control group. On the basis of treatment in the control group, yin-yang balance penetrating acupuncture was applied from Jianyu (LI 15) to Binao (LI 14), Quchi (LI 11) to Shaohai (HT 3), Yanglingquan (GB 34) to Yinlingquan (SP 9), Xuanzhong (GB 39) to Sanyinjiao (SP 6), etc. of the affected side in the observation group. The treatment was given once a day, 5 days were as one course, with a 2-day interval between two courses, 4 courses were required in both groups. The classification of modified Ashworth spasticity scale (MAS), surface integrated electromyogram (iEMG) of affected upper limb and the scores of National Institute of Health stroke scale (NIHSS), Fugl-Meyer assessment (FMA) of upper limb and modified Barthel index (MBI) before and after treatment were observed, the therapeutic effect was evaluated in both groups.


RESULTS
①After treatment, the MAS classification reduced in both groups (P<0.05), the cases of grade 0 to Ⅰ+ in the observation group were more than those in the control group (P<0.05); iEMG values of the maximum isometric voluntary contraction of affected usculus biceps brachii, musculus triceps brachii, musculus flexor carpi, musculus extensor carpi, extensor digitorum, aductor pollicis brevis were increased in both groups (P<0.05), and the variations of iEMG of above muscles on the affected side in the observation group were larger than those in the control group (P<0.05). ②After treatment, the scores of NIHSS were decreased (P<0.05), the scores of FMA, MBI were increased in both groups (P<0.05), and the variations of NIHSS, FMA and MBI scores were larger than those in the control group (P<0.05). ③The total effective rate was 93.3% (28/30) in the observation group, which was superior to 70.0% (21/30) in the control group (P<0.05).


CONCLUSION
Yin-yang balance penetrating acupuncture combined with rehabilitation training can improve upper limb spasticity, heighten the motor function of upper limb and daily self care in patients with stroke hemiplegia, its therapeutic effect is superior to single rehabilitation training.
