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.
Objectives - The primary objective is to investigate the effect of active repetitive peripheral magnetic stimulation (rPMS) in reducing pain in individuals with either tennis/golfer elbow syndrome (either medial or lateral epicondylitis) or carpal tunnel syndrome in a pilot randomized placebo-controlled clinical trial. The secondary objective is to investigate the duration of the rPMS effects up to 6 months.
Study Population - The study population will consist of two groups of individuals: one group including 10 with tennis/golfer elbow syndrome and second group including 10 with carpal tunnel syndrome. Participants will be recruited from volunteers by advertising and/or doctors' referral.
Research Design and Study Procedure - This study design is a parallel-cohort exploratory single-blind, randomized, sham-controlled study investigating the effect of rPMS in pain reduction in individuals with either elbow or wrist chronic pain. Eligible participants in each group will be stratified by condition (elbow vs carpal tunnel) and randomized within each stratum to active or sham rPMS. The sham group participants will have the option to receive the active treatment after a month of receiving the sham treatment.
The rPMS protocol is two consecutive days of therapy. In each day, the participants will receive 400 pulses at 10 HZ in 1.5 sec trains with 10-second intertrain intervals. All participants will be assessed for their pain levels at baseline, immediately post-intervention, one week after the intervention and then every month up to 6 months follow-up sessions.
The assessments include subjective Visual Analogue Scale (VAS) score for pain on a scale of 0 to 10, the minimum pressure pain threshold (PPT) and near-infrared spectroscopy (NIRS) over the target area.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Participants of this arm, suffer from chronic pain at elbow either medial or lateral epicondylitis (tennis/golder syndromes) and receive real rPMS pulses as treatment for two days successively, each day 300 pulses at 10 Hz.
Device: Two days Active rPMS
Participants of this arm, suffer from chronic pain at elbow either medial or lateral epicondylitis (tennis/golder syndromes) and receive SHAM rPMS pulses as treatment for two days successively, each day 300 pulses at 10 Hz.
Device: Two days Sham rPMS
Participants of this arm, suffer from chronic pain at wrist (carpal tunnel syndrome) and receive REAL rPMS pulses as treatment for two days successively, each day 300 pulses at 10 Hz.
Device: Two days Active rPMS
Participants of this arm, suffer from chronic pain at wrist (carpal tunnel syndrome) and receive SHAM rPMS pulses as treatment for two days successively, each day 300 pulses at 10 Hz.
Device: Two days Sham rPMS
It is a magnetic coil with a device that creates electromagnetic pulses. The Real one gives pulses with 100% intensity.
Sham coil gives very weak pulses off target that does not penetrate to the skin.
Change in pain pressure threshold (PPT)
PPT is measured by a pressure altimeter and identifies the minimum pressure that the subject feels pain.
Time frame: from baseline to post-treatment assessments on day 3 and week2 up to 6 months follow-up.
Change in visual subjective pain scale
the visual subjective pain scale is a score using 0 to 10 on the pain level.
Time frame: from Pre-intervention to post on day 3, week 1 and other post assessments up to 6 months.
Plan to share: Undecided — This is a small pilot study. Once there is enough data with good quality, the investigators will consider data sharing.

Started Jul 2026 (actual). Primary completion is estimated for Aug 2027, 13 months after the start.
Of 18 interventional studies with no phase under Elbow Tendinopathy, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 25. This study's planned 13 months is below that.
