Abstract Objective: To analyze the effects of medium frequency electrical stimulation combined with rehabilitation training on lower limb muscle strength, urinary retention and gait parameters of patients with thoracolumbar incomplete spinal cord injury. Methods: A total of 103 patients with thoracolumbar incomplete spinal cord injury admitted to the hospital between January 2018 and September 2021 were selected as the research subjects. They were divided into combined group (given medium frequency electrical stimulation combined with rehabilitation training, n=52) and conventional group (given conventional rehabilitation training treatment, n=51) according to the simple randomization method. The patients were continuously treated for 12 weeks. The lower limb muscle strength (muscle strengths of quadriceps femoris and tibialis anterior muscle) before and after treatment and improvement status of urinary retention were compared between the two groups of patients. Gait test was conducted to compare the changes in gait parameters such as step length, step frequency and step speed in the two groups before and after treatment. Functional Independence Measure (FIM) was used to compare the independent living ability before and after treatment in the two groups. Results: Generalized estimating equation results showed that muscle strength in both groups was improved, and the improvement of muscle strength in combined group was better than that in conventional group (P<0.05).The clinical effective rate of urinary retention treatment of 94.23% in combined group was higher than 80.39% in conventional group, and the efficacy grading was better in combined group than that in conventional group (P<0.05). There were no significant differences between the two groups of patients in terms of step frequency, step length and step speed before treatment (P>0.05). After treatment, the differences of the above gait parameters before and after treatment in combined group were higher compared with those in conventional group (P<0.05). Before treatment, the differences in scores of dimensions of FIM were not significant between the two groups (P>0.05). The differences of scores of FIM dimensions before and after treatment were higher in combined group compared to conventional group (P<0.05). Conclusion: Medium frequency electrical stimulation combined with rehabilitation training can improve the lower limb muscle strength, help improve the symptoms of urinary retention and gait, and enhance the independent living ability of patients with thoracolumbar incomplete spinal cord injury.
