Effects of Electrotherapy on Muscle Properties in Forward Head Posture
Sponsor: Medipol University
Summary
This randomized controlled trial investigates the acute effects of three electrotherapy modalities (therapeutic ultrasound, interferential current, and TENS) on the mechanical and viscoelastic properties of neck muscles in young adults with forward head posture. Seventy-five participants will be randomly allocated to one of three groups. Muscle stiffness, oscillation frequency, and craniovertebral angle will be assessed before and immediately after a single treatment session.

Conditions
Interventions
Therapeutic Ultrasound (Chattanooga Intelect® Vet)
Pulsed therapeutic ultrasound applied to the cervical region at 1-3 MHz frequency and 0.1-3 W/cm² intensity for 8-10 minutes in prone position, using circular head movements.
Interferential Current (Chattanooga Intelect® Vet)
Bipolar interferential current applied via two electrodes covering the target muscles, \~2500 Hz carrier frequency, 100 Hz amplitude modulation frequency, for 15 minutes, at an intensity producing a clear but painless paresthesia sensation, in prone position.
Conventional TENS
Conventional TENS applied via surface electrodes covering the target muscles, 60-120 Hz frequency, 50-100 µsec pulse duration, for 15 minutes, at an intensity producing a clear but painless paresthesia sensation, in prone position.
