Abstract:
Objective:To observe any effect of percutaneous tibial nerve stimulation (PTNS) combined with electro-acupuncture on detrusor overactivity after a spinal cord injury.Methods:Forty spinal cord injury survivors with neurogenic detrusor overactivity were randomly assigned to a control group or an observation group, each of 20. Both groups received routine bladder training and electro-acupuncture modulating 3 sacral spinal nerves. The observation group also received 20 minutes of bilateral PTNS five times a week for 8 weeks. The frequency was 10Hz with a pulse width of 200μs. Before and after the treatment, both groups′ urination frequency, incontinence and average daily urine volume were assessed using a urodynamics analyzer, bladder diaries and an incontinence quality of life questionnaire (I-QOL).Results:After treatment, the average involuntary detrusor contraction volume (IDCV), maximum detrusor pressure at filling time (P det·max), bladder compliance (BC), residual volume and the TL value of the electromyogram of the urethral sphincter (LgTLR) had all improved significantly in both groups. The 1st IDCV, BC and LgTLR of the observation group were then significantly better than in the control group, on average, with the average P det·max and residual volume significantly lower than in the control group. The average daily single urine output and I-QOL score of both groups had increased significantly, while the average daily urination frequency and frequency of urinary incontinence had decreased significantly. Both were again significantly better in the observation group. Conclusion:Combining percutaneous electrical stimulation of the tibial nerves with electro-acupuncture can effectively inhibit detrusor overactivity after a spinal cord injury, reducing urinary incontinence.
