新開發肌電回饋頸椎牽引機初步臨床試用評估 : 牽引過程頸椎肌電位反應比較

Abstract

The intermittent cervical traction is a popular physical therapeutic device for relieving neck pain or cervical radiculopathy. In this paper, the clinical evaluation of a newly developed traction modality with electromyography biofeedback was presented. Twenty four patients with neck pain were divided into high tension and low tension group according to the severity of muscle spasm. The subjects were farther randomly separated into two subgroups. The control and experimental subgroup were treated with conventional and new biofeedback traction modalities respectively. Each subject was treated in sitting position for twenty minutes every other day for seven weeks. The reduction of the average C5 paraspinal muscle EMG signal during traction in each week were collected for assessment.The results of this study show that before traction the average EMG signal of control and experimental subgroup in high tension group were 8.78±0.13μV and 8.54±0.23μV respectively. In low tension group were 4.58±0.15μV and 4.39±0.16μV respectively. After traction for a period of seven weeks, the average EMG signal of control and experimental subgroup in high tension group were reduced to 4.58±0.24μV and 1.88±0.10μV (p＜0.05) respectively. In low tension group were 2.08±0.19μV and 1.78±0.10μV (p＜0.05). From this clinical study, the newly designed cervical traction device with real-time traction weight adaptive control based on EMG biofeedback was found to be more effective in treating patient with neck pain. The results of this study indicated that the use of intermittent cervical traction in sitting position could produce cumulative effect on paraspinal muscle relaxation. The effect of paraspinal muscle relaxation over 7-weeks treatment duration using biofeedback traction device was better than that using conventional protocol. However, there is no significant differences in reduction of EMG activities for patients with neck pain but without muscle spasm between biofeedback and conventional traction treatment.
