Subsequently, one may also ask, does a TENS unit promote healing?CONCLUSION. It is suggested that TENS stimulates skin wound healing and tendon repair, as well as the viability of random skin flaps. Such effects may be due to the release of SP and CGRP, which would increase blood flow and, consequently, hasten the events of tissue repair.Subsequently, question is, how long does Tens pain relief last? Length of pain relief The post-stimulation analgesic effects of TENS can therefore last anywhere from five minutes to 18 hours (Woolf, 1991). Some patients’ pain levels do not return to pre-stimulation levels even after 24 hours (Cheing et al, 2003). Also, how often should you use a TENS unit? You can safely use a TENS machine as often as you like. Usually for 30-60 minutes up to 4 times daily. TENS can provide relief for up to four hours.Do TENS units really work?Due to a lack of high-quality research and clinical trials, researchers have not yet determined whether TENS is a reliable treatment for pain relief. One study found that TENS treatment provided temporary pain relief for people with fibromyalgia while the machine was in use.
