AIM: To observe the ameliorative effect of transcutaneous electrical nerve stimulation matched with early rehabilitative training on memory and motor function in patients with stroke.METHODS:Sixty patients with stroke, having clinical situation of memory retention disorder, who were hospitalized at the Department of Neurology and Department of Rehabilitation Medicine,Sixth Affiliated People's Hospital, Shanghai Jiaotong University and Department of Rehabilitation Medicine, Central Hospital of Xuhui District of Shanghai from February to December 2003,were selected.They all agreed to take part in the experiment, and assigned randomly into 2 groups: treatment group and control group with 30 in each group. The patients in the treatment group were treated with transcutaneous electrical nerve stimulation and routine rehabilitative training; Those in the control group were treated with routine rehabilitative training only. ① Transcutaneous electrical nerve stimulation: treatment on spinal cord (output of therapy adjusted to spring of the muscle, and the patients could bear), treatment on limb of injured side (mild tic of limb, and the patients could bear), once a day, 6 times every week for 4 weeks continuously. ② Routine rehabilitative training: once a day, 5 times in every week for 4 weeks continuously. Memory ability in patients of the two groups was assessed with clinical memory measuring scale. The measured original scores were changed into scale score, then converted into memory quotient (taking 85 points as a border, memory quotient ≤ 85 points as abnormal memory). Motor function was assessed with Fugl-Meyer motor assessment (Upper limb: 66 points; lower limb: 34 points; totally 100 points). The assessments of memory ability and motor function were detected once before treatment and before discharge, respectively. The recovered condition of memory and limb motor function in patients of the two groups was compared. RESULTS: Totally 60 included stroke patients were involved in the result analysis, without drop. ① Comparison on memory quotient in patients of the two groups: It increased significantly after treatment as compared with before treatment in the treatment group and control group 80.2±12.1,70.6±0.5;61.2±11.0,62.8±12.0(t=3.90,6.70,P 0.01).It was higher significantly in the treatment group after treatment than that in the control group (t=4.50,P 0.01). ② Comparison on motor function with Fugl-Meyer score in patients of the two groups: The score of motor function with Fugl-Meyer after treatment in the treatment group and control group increased significantly than that before treatment upper limb:23.12±4.20,21.46±4.35;16.20±5.20,15.23±4.50;lower limb:24.12±5.20,17.30±4.30;10.05±4.20,9.24±5.80(t=5.1-6.5,P 0.05). The score on lower limb with Fugl-Meyer in patients of treatment group after treatment was higher significantly than that of control group (t=4.32,P 0.01). CONCLUSION: The transcutaneous electrical nerve stimulation matching with routine rehabilitative training can more effectively ameliorate memory function and limb motor disorder in stroke patients as compared with pure rehabilitative training.
