Summary
Transcutaneous electrical nerve stimulation (TENS) effectively improved bladder capacity in individuals with spinal cord injury (SCI). This safe treatment shows promise for neurogenic bladder dysfunction, though further research is needed.
Area of Science:
- Neuroscience
- Urology
- Rehabilitation Medicine
Background:
- Neurogenic bladder dysfunction is a common complication of spinal cord injury (SCI).
- It significantly impacts patients' quality of life and requires effective management strategies.
- Transcutaneous electrical nerve stimulation (TENS) is a potential therapeutic option.
Purpose of the Study:
- To evaluate the efficacy of TENS in treating neurogenic bladder dysfunction in SCI patients.
- To analyze the impact of TENS on key urodynamic parameters.
Main Methods:
- A systematic review and meta-analysis of randomized controlled trials (RCTs) were conducted.
- Searches included major scientific databases up to February 2021.
- Primary outcomes were maximum cystometric capacity (MCC) and maximum detrusor pressure (Pdet).
Main Results:
- Six RCTs with 353 participants were analyzed.
- TENS significantly increased MCC in acute SCI patients (SMD 1.11, p=0.03).
- No significant effect on Pdet was observed, and TENS was well-tolerated with no major adverse events.
Conclusions:
- TENS appears to be a safe and effective intervention for neurogenic bladder dysfunction post-SCI.
- Further research is warranted to confirm these findings.
- Optimal TENS parameters and treatment durations require further investigation.
