Description

This pilot, randomized, sham-controlled, single-blind study will evaluate the effectiveness of repetitive peripheral magnetic stimulation (rPMS) in reducing pain in adults with tennis/golfer's elbow or carpal tunnel syndrome. Approximately 40 participants will be randomly assigned to active or sham stimulation delivered over two consecutive days. Outcomes, including pressure pain threshold, subjective pain ratings, and local tissue oxygenation (fNIRS), will be assessed at baseline, immediately post-intervention, and during follow-up up to 6 months to evaluate both clinical effects and underlying physiological mechanisms.

Interventions

Two days Active rPMS (Device)
It is a magnetic coil with a device that creates electromagnetic pulses. The Real one gives pulses with 100% intensity.
Two days Sham rPMS (Device)
Sham coil gives very weak pulses off target that does not penetrate to the skin.

Eligibility criteria

Inclusion Criteria: * Clinical diagnosis or self-reported history consistent with either medial or lateral epicondylitis or carpal tunnel syndromes. * Presence of chronic pain in the target area (mentioned above) at the time of enrollment. * Ability to understand the study procedures and provide informed consent. Exclusion Criteria: * Contraindications to peripheral magnetic stimulation, including implanted electronic medical devices or metallic implants in locations deemed unsafe for stimulation. * Open wounds, active skin conditions, or other local conditions at the stimulation site. * Current neurological, musculoskeletal, or systemic medical conditions that, in the opinion of the investigators, would interfere with safe participation or interpretation of study outcomes. * Current upper-limb injury or condition other than tennis/golfer elbow or carpal tunnel syndromes that could confound pain or perfusion measurements. * Pregnancy. * Inability to tolerate the stimulation or measurement procedures. * Inability to adequately understand study instructions or provide informed consent.
