Objective To investigate the therapeutic effect of acupoint catgut embedding on balance function and plantar pressure in hemiplegic patients. Methods A total of 98 hemiplegic patients were equally randomly assigned to routine treatment group and acupoint catgut embedding group. The patients in the routine treatment group were given routine medical treatment

routine acupuncture and rehabilitation training. And those in the catgut embedding group were given catgut embedment at Shenshu(BL23)

Xinshu(BL15)

Ganshu(BL18)

Pishu(BL20)

Guanyuan(CV4) and Qihai(CV6) in addition to the treatment in the routine treatment group. The course of treatment was 3 weeks for both groups. The plantar pressure as well as the Berg balance scale(BBS) score were measured before and after treatment. Results(1) After 3 weeks treatment

the percentage of static plantar pressure of the affected foot was significantly increased in the two groups compared with their own pre-treatment(P<0.05

P<0.01)

and it was significantly higher in the catgut embedding group than in the routine treatment group after one week treatment(P<0.01).(2) After 3 weeks treatment

the peak pressures of the following parts in the catgut embedding group increased significantly in comparison to its own pre-treatment(P<0.05

P<0.01)

which were 1) the first toe(affected foot)

2) the first metatarsal bone(affected foot)

3) the third metatarsal bone(affected foot)

4) the middle of foot(affected foot)

5) the medial heel(affected foot). After 3 weeks treatment

the peak pressures of the first metatarsal bone and the medial heel of the affected foot in the routine treatment group were significantly higher than those before treatment(P<0.05). After 1 week treatment

the peak pressure of the first toe of the affected foot in the embedding group was significantly higher than that in the routine treatment group(P<0.05). The peak pressures of the first metatarsal bone and the middle of the affected foot in the catgut embedding group were significantly higher than those in the routine treatment group after one and two weeks treatment(P<0.01

P<0.05). After 1

2 and 3 weeks treatment

the peak pressure in the middle of the healthy foot in the embedding group was significantly lower than that in the routine treatment group(P<0.01).(3) After 3 weeks treatment

the BBS scores of the two groups were significantly higher than those before treatment(P<0.05)

and the BBS score of the embedding group was significantly higher than that of the routine treatment group(P<0.05). Conclusion Acupoint catgut embedding can effectively improve the plantar pressure and balance function of stroke patients with hemiplegia.
