Objective: The aim of the study was to investigate the therapeutic efficacy of transcutaneous electrical nerve stimulation (TENS) in the symptomatic management of chronic prostatitis pain/chronic pelvic pain syndrome. Design: A pretest, posttest randomized double blind design was used in data collection. Participant: Twenty-four patients diagnosed with chronic prostatitis-category IIIA and IIIB of the National Institute of Health Chronic Pain (NIH-CP) were referred for physiotherapy from the Urology department. Intervention: Pre treatment pain level was assessed using the NIH-CP (pain domain) index. The TENS group received TENS treatment, 5 times per week for a period of 4 weeks (mean treatment frequency, intensity, pulse width and duration of 60Hz, 100µS, 25mA and 20 minutes respectively). The Analgesic group received no TENS treatment but continued analgesics; the Control group received no TENS and Analgesic but placebo. All subjects were placed on antibiotics throughout the treatment period. Outcome measures: Post-treatment pain level was also assessed using NIH-CP pain index. Result: Findings of the study revealed significant effect of TENS on chronic prostatitis pain at p < 0.05. Conclusion: TENS is an effective means of non-invasive symptomatic management of chronic prostatitis pain.
