Improvement effect of electromyographic biofeedback on wrist dorsiflexion function of patients with cerebral infarction at different Brunnstrom stages / 吉林大学学报(医学版)

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-Ⅱ patients 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).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.

Motor Recovery in Relation to the Site of Subcortical Stroke Lesions

OBJECTIVE: The purpose of this study was to evaluate the motor recovery of initial and plateau period in the patients with subcortical stroke lesion which were different locations. METHOD: We studied the 42 stroke patients with subcortical lesions who had been admitted to the Department of Rehabilitation Medicine from 1998 to 2000, retrospectively. Patients were divided into four groups according to the information from brain CT or MRI; Group 1: basal ganglia, group 2: anterior limb of internal capsule and/or basal ganglia, group 3: posterior limb of internal capsule and/or basal ganglia and group 4: thalamus only. Quantitative assessments of motor recovery using the Brunnstrom stage and results were correlated with sites of lesion. RESULTS: 1) Brunnstrom stages at initial and plateau period were the highest in the patients with thalamic lesion and the lowest in the patients with posterior limb of internal capsule and/or basal ganglia lesion. The patients with thalamic lesion showed higher stage than the patients with basal ganglia with anterior limb lesion in hand and low extremity (p<0.05). 2) Significant motor recovery was occurred in all patients except the lesion located in thalamus (p<0.05). CONCLUSION: There were significant differences of motor recovery at plateau period in the patients with thalamic lesions comparing with basal ganglia with anterior limb lesion about hands and lower extremities and patients with basal ganglia and/or capsular lesion showed good motor recovery.
