A RCT to determine the duration of analgesia after 15&30-minutes of acupuncture-like TENS on patients with chronic lbp

Acupuncture-like TENS (AL-TENS) has been shown to produce prolonged pain relief, but no study has yet investigated its duration on a population suffering from chronic low back pain (CLPB). The objective of the study was to objective was to quantify the duration and magnitude of analgesia induced by a 15- or 30-minute application of AL-TENS.

The AL-TENS applications induced a clinically and statistically significant (p = 0.003) analgesia in all participants. Median duration of analgesia was 9 hours and 10 hours 30 minutes following the 15- and 30-minute AL-TENS applications, respectively; this 1.5-hour difference was not statistically significant (p = 0.55). Furthermore, we observed no significant difference in the magnitude of analgesia between both applications of AL-TENS (p > 0.56), suggesting that the duration of application of AL-TENS does not influence the magnitude of analgesia. The results suggest that clinicians could use a 15-minute AL-TENS application to provide significant analgesia in patients presenting with low back pain since if provides a comparable analgesia versus a 30-minute application.

Neck Pain

Out of all 291 conditions studied in the Global Burden of Disease 2010 Study, neck pain ranked 4th highest in terms of disability and 21st in terms of overall burden.
