Contralateral Antalgic Effect of HF-TPNS

What is it about?

Transcutaneous electrical nerve stimulation (TENS) is the most widespread analgesic electrotherapy in rehabilitation practice. Little is currently known about possible effects of TENS in body regions distant from the stimulation site. The aim of the study was to investigate the analgesic effect of high-frequency transcutaneous peripheral nerve stimulation (HF-TPNS) in the ipsilateral and contralateral skin territory of the stimulated nerve.

Why is it important?

The present study demonstrates an analgesic effect of High-Frequency Transcutaneous Peripheral Nerve Stimulation not only in the ipsilateral but also in the contralateral side of stimulation, suggesting a possible role of contralateral HF-TPNS in the treatment by physical therapy of patients with unilateral pain syndromes.
