Comparative Study on the Efficacy of Different Frequency Functional Magnetic Stimulation Combined with Motor Imagery Therapy in the Treatment of Neurogenic Bladder Urinary Retention after Spinal Cord Injury
Objective:To observe the efficacy of different frequency functional magnetic stimulation(FMS)combined with motor imagery therapy in the treatment of neurogenic bladder(NB)urinary retention after spinal cord injury(SCI).Methods:116 patients with NB urinary retention after SCI who were admitted to our hospital from August 2021 to April 2023 were divided into 5Hz group(n=58,5HzFMS combined with motor imagery therapy)and 20Hz group(n=58,20HzFMS combined with motor imagery therapy)according to the random number table method.The urination,urodynamic indexes,electromyography indexes and various scale scores were com-pared between two groups.Results:After treatment,the number of daily spontaneous urination in 20Hz group was less than that in 5Hz group,and the average daily single urination volume and the maximum daily single urination volume were more than those in 5Hz group(P＜0.05).The maximum urinary flow rate,maximum bladder capacity,detrusor pressure during filling period,H reflex amplitude,F wave extraction rate and quality of life comprehensive scale-74(GQOL-74)score in 20Hz group were higher than those in 5Hz group,and the bladder residual urine volume,H reflex latency,F wave latency,NB symptom score(NBSS)and international lower urinary tract function symptom(LUTS)score were lower than those in 5Hz group(P＜0.05).Conclusion:Compared with 5Hz frequency FMS,20Hz frequency FMS combined with motor imagery therapy for NB urinary retention after SCI can alleviate clinical symptoms,promote blad-der function recovery,and further improve the quality of life of patients.
