Abstract

Objective To explore the clinical efficacy of transcranial combined peripheral magnetic stimulation on bladder and voiding ability in patients with NB after spinal cord injury. Methods From September 2023 to October 2024， 60 patients with NB after spinal cord injury were chosen from the Department of Rehabilitation Medicine of the First Affiliated Hospital of Bengbu Medical University， and were separated into the regular group （n = 15）， M1 area stimulation group （n = 15）， sacral nerve root stimulation group （n = 15）， and combined stimulation group （n = 15）. The control group underwent conventional rehabilitation treatment， the M1 area stimulation group added repetitive transcranial magnetic stimulation （rTMS） of the M1 area of the motor cortex， the sacral nerve root stimulation group added repetitive peripheral magnetic stimulation （rPMS） of the sacral 3 nerve roots， and the co-stimulation group added rTMS of the M1 area and rPMS of the sacral 3 nerve roots， and the treatment was carried out for 4 weeks in total. Urodynamic indices， voiding diaries， and neurogenic bladder symptom scores （NBSS） were assessed before and after therapy in the four groups. Results Before therapy， the differences in maximum bladder capacity， bladder capacity at the time of the first urge to urinate， maximum urine flow rate， residual urine volume， average number of urination per day， average daily urinary output， and NBSS scores of the four groups were not statistically significant when compared with those of the pre-treatment group （P < 0.05）； after treatment， the maximum bladder capacity， bladder capacity at the time of the first urge to urinate， maximum urine flow rate， residual urine volume， average number of urination per day， average daily urinary output， and NBSS scores were all improved compared with those before treatment （P < 0.05）； in comparison between the groups， after treatment， the Urodynamic indices， voiding diaries， and NBSS scores of the combined group were better than those of the other three groups （P < 0.05）. Conclusion Transcranial combined peripheral bidirectional feedback magnetic stimulation therapy can improve urodynamic and voiding symptoms and promote the recovery of bladder and voiding function in patients with NB after spinal cord injury
