Summary

This randomized controlled trial investigates the acute effects of transcutaneous electrical nerve stimulation (TENS) on passive cervical muscle stiffness (MyotonPro "dynamic stiffness", N/m) and pain (0-10 VAS) in adults with chronic/mechanical neck pain. Participants will be allocated 1:1 to TENS or control/sham. Outcomes are measured immediately before and immediately after a single 15-minute session.

Conditions

  • Neck Pain
  • Chronic Neck Pain
  • Muscle Stiffness
  • Transcutaneous Electrical Nerve Stimulation

Interventions

DEVICE

Transcutaneous Electrical Nerve Stimulation

Conventional mode TENS, frequency \~80 Hz, pulse width ≤150 µs, duration 20 minutes. Intensity set to "strong but tolerable" without visible muscle contraction. Electrodes placed bilaterally over the most painful/stiff segments (e.g., upper trapezius midpoint along C7-acromion line; adjustments per comfort

DEVICE

Sham TENS

Electrodes applied at the same anatomical sites as the active arm. Device indicators remain on; intensity is ramped to perception briefly and then reduced to sub-sensory/zero so that no effective current is delivered for the remainder of the 20-minute session. Procedures and clinician-participant interactions mirror the active arm
