Effect of magnetic stimulation of primary motor cortex（M1） on bladder function in patients with incomplete spinal cord injury

Abstract:

Objective：To investigate the effect of magnetic stimulation of the primary motor cortex（M1） on bladder function in patients with incomplete spinal cord injury（SCI）. Methods：A total of 60 SCI patients with neurogenic bladder were randomly divided into experimental group，sham stimulation group，and control group. The patients in the experimental group were given conventional treat－ment combined with magnetic stimulation of M1，those in the sham stimulation group were given the same treatment as the experimen－tal group without magnetic stimulation，and those in the control group were given conventional treatment alone. The three groups were compared in terms of voiding diary，urodynamic parameters，and Qualiveen score before and after treatment. Results：All three groups had significant improvements in residual urine volume，daily single voided volume，bladder compliance，maximum urinary flow rate，maximum bladder capacity，and Qualiveen score after treatment（P<0.05），and there were significant differences in these indices between the experimental group and the other two groups（P<0.05）. Conclusion：Magnetic stimulation of primary motor cortex can improve bladder function in patients with incomplete SCI.
