【Abstract】 Objectives: To explore the effects of functional magnetic stimulation(FMS) in patients with neurogenic overactive bladder after spinal cord injury. Methods: Forty patients with neurogenic overactive bladder after spinal cord injury were randomly divided into FMS group(20 patients) and control group(20 patients) by using a random number table. Both groups received the functional training of bladder, the FMS group was additionally given FMS(The intensity was 70%-100% of the maximum output intensity, the frequency was 15Hz, and the stimulation was 5s every minute for a total of 30min, once a day, five times a week, for a total of 8 weeks), the control group was given same parameter FMS(but the stimulation coil was perpendicular to the treatment site and had no stimulation effect). Urodynamics, urination diary record indexes(single urine volume, number of urination and maximum urination volume) and quality of life score changes caused by urination symptoms were compared between the two groups before and after treatments lasted for 8 weeks. Results: After 8-week treatment, the urodynamic indexes of the control and FMS groups were as follows: bladder volume(65.25±6.41ml, 78.44±9.52ml) increased at first urine intention (P<0.05), maximum bladder manometric capacity(339.55±36.75ml, 394.46±36.68ml) increased significantly(P<0.05), and residual urine volume(120.22±40.35ml, 88.25±33.61ml) decreased significantly(P<0.05). The daily average single urination volume(120.06±23.23ml, 150.28±24.24ml) increased(P<0.05), the average 24-hour urination frequency(12.28±3.31, 9.44±3.95) decreased(P<0.05), and the maximum urination volume(233.58±47.14ml, 274.51±30.18ml) improved significantly(P<0.05). The quality of life score was significantly reduced due to urination symptoms. Compared within group before treatment, the difference was statistically significant(P<0.05), and the improvement of the treatment group was significantly better than that of the control group (P<0.05). Conclusions: FMS can improve the bladder function and the quality of life in patients with neurogenic overactive bladder. |
