Abstract:
Objective:To observe the effect of microelectronic EMG bridge (EMGB) training on the motor function of extensor carpi radialis longus in patients with complete cervical 5 spinal cord injury. Methods:From March, 2016 to March, 2017, 20 patients with complete cervical 5 spinal cord injury were randomly divided into control group (n = 10) and experimental group (n = 10). The control group received routine wrist extensor muscle training, and the experimental group received EMGB training in addition, for 180 days. The motor function of the affected limb was evaluated by sEMG of extensor carpi radialis longus, Manual Muscle Test (MMT), Wolf Motor Function Test (WMFT) and Spinal Cord Lesion Independence Measure (SCIM). Results:After treatment, the peak value and average value of sEMG of extensor carpi longus of both sides increased in both groups (t > 2.510, P < 0.05), the peak value and average value of the left side were higher (t > 2.759, P < 0.05), and the peak value of the right side was higher (t = 2.691, P < 0.05) in the experiment group than in the control group, however, there was no significant difference in average value of the right side between two groups (t = 2.063, P = 0.054). The scores of MMT increased in both groups (t > 2.569, P < 0.05), and were higher in the experimental group than in the control group (t > 2.278, P < 0.05). The scores of WMFT and SCIM increased in both groups (t > 3.839, P < 0.05), however, there was no significant difference between two groups (t < 1.498, P > 0.05). Conclusion:EMGB training could improve the motor function of extensor carpi radialis longus in patients with complete cervical 5 spinal cord injury.
