Abstract:

Objective: To observe the effect of electromyographic biofeedback on the wrist dirsiflexion function of the patients with cerebral infarction at different Brunnstrom stages, and to clarify the treatment of electromyographic biofeedback,and to provide basis for its clinical application. Methods: A total of 100 cerebral infarction patients were selected.Among them 54 BrunnstromⅠ-Ⅱpatients were randomly divided into treatment group (n=32) and control group (n=22),and another 46 Brunnstrom Ⅲ patients were randomly divided into treatment group (n=23) and control group (n=23). The patients in four groups were treated with the same routine stroke rehabilitation therapy while the patients in treatment groups still received the electromyographic biofeedback therapy additionally. The maximum electromyographic contraction of muscle, active range of movement (AROM)and Fugl-Meyers Assessment (FMA) of the extension of wrist joint were evaluated before treatment and 4 and 8 weeks after treatment, respectively. Results: The maximum electromyographic contraction values of muscle of the patients in BrunnstromⅠ-Ⅱ treatment group and control group were significantly improved 8 weeks after treatment(P<0.05),and the value in treatment group was higher than that in control group(P<0.05).The maximum electromyographic contraction value of muscle in Brunnstrom Ⅲ treatment group began to improve 4 weeks after treatment compared with before treatment (P<0.05) and it was significantly higher than that in control group(P<0.05).The maximum electromyographic contraction value of muscle in Brunnstrom Ⅲ control group began to improve 8 weeks after treatment (P<0.05).The AROM in Brunnstrom Ⅰ-Ⅱ treatment group began to improve 8 weeks after treatment (P<0.05) and it was significantly higher than that in control group(P<0.05) while the AROM in control group had no significant change(P>0.05).The AROM in Brunnstrom Ⅲ treatment group and control group were significantly improved 4 weeks after treatment(P<0.05 or P<0.01),and the value in treatment group was significantly higher than that in control group(P<0.05).The FMA in BrunnstromⅠ-Ⅱtreatment group and control group were significantly improved 8 weeks after treatment(P<0.05),while the value in treatment group was higher than that in control group(P<0.05); the FMA in Brunnstrom Ⅲ treatment group began to improve 4 weeks after treatment (P<0.05) and it was significantly higher than that in control group(P<0.05).The FMA in control group began to improve 8 weeks after treatment (P<0.05). Conclusion: Electromyographic biofeedback can increase the strength and improve the body function of the patients with cerebral infaction.
