目的：为了确定是否肌电图（EMG）生物反馈程序使用操作性条件反射范式可以显着增加自愿肌电图反应从三头肌的长期颈脊髓injureds.Design：干预研究与前后试验测量与每个主题作为自己的控制。100名C6或更高颈髓损伤持续时间超过1年，并且力量低于正常水平和肱三头肌可记录的EMG活动，并且功能恢复达到平台期的个体。前100个人符合这一标准谁顺序进行肌电图测试和生物反馈。干预：在肘关节伸展尝试过程中获得肌肉力量和表面EMG记录。EMG预测试数据来自于在肘部伸展期间记录的来自三头肌的最高平均自愿EMG反应。为100名受试者中的每一名提供了一次45分钟的操作性条件反射范式中用于三头肌的EMG生物反馈治疗。75名受试者平均接受了3次额外的生物反馈治疗。测试后的EMG数据来自于45分钟生物反馈治疗期间和最后一次额外生物反馈治疗期间的肱三头肌的EMG测量，其方式与测试前程序相似。肌电活动的显著增加发生在三头肌（p < .001），并且在额外的生物反馈治疗期后发生EMG活动的进一步显著增加（p < .001）。初始肌肉力量和初始EMG水平没有决定性因素的响应biofeedbacks.Conclusions：结果表明，生物反馈的有效性增加自愿肌电图反应在长期脊髓损伤患者。(C)1996年由美国康复医学大会和美国物理医学和康复学会。
Objective: To determine if electromyography (EMG) biofeedback procedures using an operant conditioning paradigm could significantly increase voluntary EMG responses from the triceps muscles of long term cervical spinal cord injured individuals.Design: Intervention study with before-after trial measurement with each subject as its own control.Setting: University outpatient clinic.Participants: One hundred individuals with cervical spinal cord injuries C6 or higher that were greater than 1-year duration, and who had less than normal strength and recordable EMG activity from the triceps, and who had reached a plateau in return of function. The first 100 individuals meeting this criteria who presented sequentially for EMG testing and biofeedback were included. No subjects were deleted from the sample.Intervention: Muscle strength and surface EMG recording during attempts at elbow extension were obtained. The EMG pretest data were derived from the highest average recorded voluntary EMG response from the triceps during elbow extension. One 45-minute treatment session of EMG biofeedback for the triceps in an operant conditioning paradigm was provided for each of the 100 Subjects. Seventy-five subjects received an average of 3 additional biofeedback treatment sessions. The posttest EMG data were derived from EMG measurements of the triceps during attempts at elbow extension from the 45-minute biofeedback treatment session and from the last additional biofeedback treatment session in a similar manner to the pretest procedures.Main Outcome Measures: A significant increase in EMG activity occurred from the triceps (p < .001) after one biofeedback treatment session and further significant increases in EMG activity occurred after additional biofeedback treatment sessions (p < .001). Initial muscle strength and initial EMG levels were not determining factors for response to the biofeedback.Conclusions: The results suggest the efficacy of biofeedback for increasing voluntary EMG responses in long term spinal cord injury patients.
