Shocking relief? electrical zaps tested for achilles pain
NCT ID NCT07453485
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a quick session of electrical stimulation can lower pain and help people with Achilles tendon injuries move better. About 30 adults with Achilles tendinopathy or a past rupture will try two different stimulation methods. The goal is to see if this approach offers fast, temporary relief during a simple heel-raise exercise.
