| Objective: To observe the effects of electromyographic (EMG) biofeedback therapy combined with rehabilitation training on movement dysfunction of lower limb after spinal cord injury (SCI). Methods: Sixty cases of incompletely thoracic-lumbar SCI were randomly divided into experimental group and control group, 30 cases in each group. All the patients received routine rehabilitation, and the patients in the experimental group received EMG biofeedback therapy additionally. They were assessed with surface electromyographic (sEMG) signal and muscle strength grading data before and after rehabilitation, and the clinical curative efficacy was compared. Results: The sEMG signal and strength of the quadriceps and Pretibial muscle in both two groups were increased after 8-week treatment (P<0.05), and continuously increased after 12-week treatment (P<0.01). The increase of sEMG signal in experimental group was higher than in the control group after treatment (P<0.05). The scores of ASIA motor function and FIM in two groups were increased obviously after 8-week treatment as compared with those before treatment (P<0.05), but there was no significant difference between two groups. The scores of ASIA motor function and FIM in two groups were increased more obviously after 12-week treatment than those after 2-week treatment (P<0.01). The increase of scores in experimental group was significantly higher than in control group (P<0.05). Conclusion: The EMG biofeedback therapy combined with rehabilitation training is effective for movement dysfunction of lower limb after SCI, which can significantly improve the sEMG signal and muscle strength of quadriceps and Pretibial muscle. Moreover, it can improve the level of functional independence, and reduce complications. |
