OBJECTIVETo evaluate the efficacy on hemiplegic spasticity after cerebral infarction treated with plum blossom needle tapping therapy at the key points and Bobath therapy.

METHODSEighty patients were collected, in compliance with the inclusive criteria of hemiplegic spasticity after cerebral infarction, and randomized into an observation group and a control group, 40 cases in each one. In the control group, Bobath manipulation therapy was adopted to relieve spasticity and the treatment of 8 weeks was required. In the observation group, on the basis of the treatment as the control group, the tapping therapy with plum blossom needle was applied to the key points, named Jianyu (LI 15), Jianliao (LI 14), Jianzhen (SI 9), Hegu (LI 4), Chengfu (BL 36), Zusanli (ST 36), Xiyangguan (GB 33), etc. The treatment was given for 15 min each time, once a day. Before treatment, after 4 and 8 weeks of treatment, the Fugl-Meyer assessment (FMA) and Barthel index (BI) were adopted to evaluate the motor function of the extremity and the activity of daily life in the patients of the two groups separately. The modified Ashworth scale was used to evaluate the effect of anti-spasticity.

RESULTSIn 4 and 8 weeks of treatment, FMA: scores and BI scores were all significantly increased as compared with those before treatment in the two groups: (both P<0. 05). The results in 8 weeks of treatment in the observation group were significantly better than those in the control group (all P<0. 05). In 4 and 8 weeks of treatment, the scores of spasticity state were improved as compared with those before treatment in the patients of the two groups (all P<0. 05). The result in 8 weeks of treatment in the observation group was significantly better than that in the control group (P<0. 05). In 8 weeks of treatment, the total effective rate of anti-spasticity was 90. 0% (36/40) in the observation group, better than 75. 0% (30/40) in the control group (P<0. 05).

CONCLUSIONThe tapping therapy with plum blossom needle at the key points combined with Bobath therapy effectively relieves hemiplegic spasticity in the patients of cerebral infarction and improves the motor function of extremity and the activity of daily life.

OBJECTIVETo compare the effects between plum-blossom needle tapping at Jiaji (EX-B 2) combined with rehabilitation and simple rehabilitation for ataxia of cerebellar apoplexy.

METHODSSixty patients with ataxia of cerebellar apoplexy were randomly divided into an observation group,and a control group,30 cases in each one. Conventional rehabilitation training was applied in the control group. While based on the treatment as that of the control group, plum-blossom needle tapping at Jiaji (EX-B 2) was used in the observation group. All the treatment was given for 4 weeks. International cooperative ataxia rating scale (ICARS), Berg balance scale (BBS) and Barthel index (BD were observed before treatment,after 2-week treatment and 4-week treatment. Also, clinical effects After treating for 2 weeks and for 4 weeks, the results of ICARS,BBS and BI were obvi were compared.

RESULTSAfter treating for 2 weeksand for 4 weeks, the results of ICARS, BBS and BI were obviously better than those before treatment in the two groups (all P<0.05). After 2-week treatment,there was no sta tistical significance between the two groups (all P>0. 05). After 4-week treatment,all the scores of the observation group were apparently superior to those of the control group (all P<0. 05). The total effective rate was 96. 7% (29/30) in the observation group, better than 80. 0% (24/30) in the control group after 4-week treatment (P<0. 05). CCONCLUSION:Plum-blossom needle tapping at Jiaji(EX-B 2) combined with rehabilitation training markedly improve the coordination and balance functions and activities of daily life, which are better than simple rehabilitation.
