BACKGROUND & OBJECTIVE
Transcutaneous electrical nerve stimulation (TENS) has been used for symptomatic relief of pain worldwide, but the efficacy and safety of TENS continues to be questioned. The uncertainty about the safety and efficacy of TENS has led to confusion among clinicians and policymakers alike. Clinical practice guidelines do little to clarify the best path, as some guidelines do recommend the use of TENS for pain, depending on the medical diagnosis.
The goal of this systematic review and meta-analysis was to evaluate the efficacy and safety of TENS for pain regardless of the medical diagnosis in adults.
Transcutaneous electrical nerve stimulation (TENS) has been used for symptomatic relief of pain worldwide, but the efficacy and safety of TENS continues to be questioned.
TENS activates inhibitory mechanisms that reduce central excitability which does lead to a reduction of pain.
