| Objective Early rehabilitation after spinal cord injury is the most important function recovery.At present,electromyographic biofeedback therapy is gradually applied to rehabilitation training after cerebral infarction and spinal cord injury.Therefore,this study combined with myoelectric biofeedback therapy and rehabilitation Effects of lower limb muscle strength and gait(step length,pace,and frequency)in patients with complete spinal cord injury.Methods A total of 42 patients with incomplete spinal cord injury and lower extremity dysfunction admitted to the Department of Orthopedics,Ma’anshan People’s Hospital and Department of Rehabilitation,Maanshan Traditional Chinese Medicine Hospital from July 2017 to April 2019 were randomly divided into treatment groups and controls according to the time of patients’ rehabilitation 21 cases in each group.Both groups received traditional rehabilitation treatments such as joint active and passive flexion and extension exercises,posture placement and posture training,lower limb robot-assisted gait training,and acupuncture.The treatment group applied EMG biofeedback therapy on this basis.Before and after rehabilitation treatment,the surface electromyography(s EMG)signal amplitude,muscle strength grading,and gait parameters(step length,pace,and frequency)were measured in the treatment group and the control group,and the observations before and after treatment were statistically analyzed in each group Indicator changes.Results(1)Comparison of quadriceps muscle strength and s EMG signal results: the quadriceps muscle strength of the treatment group increased from 2.31 ± 0.45 before treatment to 4.30 ± 0.44 after treatment,and the s MEG signal increased from 15.81 ±3.54μV before treatment To 258.91 ± 30.11μV after treatment,the difference in data before and after treatment was statistically significant(P <0.01);the strength of the quadriceps muscle in the control group increased from 2.39 ± 0.47 before treatment to3.47 ± 0.61 after treatment,s EMG signal increased from 16.73 ± 2.55μV before treatment to 184.21 ± 38.19μV after treatment,the difference in data before and after treatment was statistically significant(P <0.01);the quadriceps muscle strength and The difference between the s MEG signal groups was significant(P <0.01),the treatment group was better than the control group.(2)Comparison of tibialis anterior muscle strength and s MEG signal results: the tibialis anterior muscle strength of the treatment group increased from 2.26 ± 0.43 before treatment to 4.25 ± 0.43 after treatment,and the s MEG signal increased from10.74 ± 1.66μV before treatment to treatment After 128.87 ± 34.95μV,the difference in data before and after treatment was statistically significant(P <0.01);the muscle strength of the tibialis anterior muscle of the control group increased from 2.20 ± 0.40 before treatment to 3.31 ± 0.46 after treatment,s MEG signal From 10.51 ± 1.45μV before treatment to 75.92 ± 20.11μV after treatment,the difference between the data before and after treatment was statistically significant(P <0.01);the quadriceps muscle strength and s MEG signal group after treatment in the treatment group and the control group There is a significant difference between the two groups(P <0.01),the treatment group is better than the control group.(3)Comparison of gait parameters: the treatment group’s step length,pace and pace before treatment increased from 29.30 ± 2.31 cm,0.14 ± 0.03 m / s,20.05 ± 3.91 steps/ min to 49.31 ± 6.51 cm,0.39 ± 0.04 m / s,64.21 ± 4.92 steps / min,the difference in data before and after treatment was statistically significant(P <0.01);the step length,pace,and pace before treatment in the control group were 28.25 ± 2.32 cm,0.14 ±0.03 m / s,19.91 ± 5.22 The step / min increased to 44.39 ± 5.26 cm,0.30 ± 0.03 m / s,51.39 ± 6.50 steps / min after treatment.The difference in data before and after treatment was statistically significant(P <0.01);After the treatment,the stride frequency was significantly different between the treatment group and the control group(P <0.05),while the step length was not significantly improved compared with the control group(P > 0.05).Conclusion Compared with traditional rehabilitation training,myoelectric biofeedback therapy can more effectively promote the recovery of lower limb motor function in patients with incomplete spinal cord injury,and can significantly improve the autonomic myoelectric signals,muscle strength and gait parameters of the main muscle groups of lower limbs.(Pace rate,step frequency)indicators are important for the prognosis of patients’ walking ability. |
