Virkninger av perifer repetitiv perifer magnetisk stimulering på personer med kronisk albu- eller håndleddssmerte (rPMS)
Effekter av perifer repeterende perifer magnetisk stimulering hos personer med kronisk smerte i albue eller håndledd, en pilot randomisert kontrollert studie
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.

Detaljert beskrivelse
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.

|---|---|

Eksperimentell: Two days active rPMS - Tennis/golfer syndrome
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. |
It is a magnetic coil with a device that creates electromagnetic pulses. The Real one gives pulses with 100% intensity. |
|
Sham-komparator: Two days sham rPM - Tennis/golfer syndrome
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. |
Sham coil gives very weak pulses off target that does not penetrate to the skin. |
|
Eksperimentell: Two days Active rPMS - Carpal Tunnel Syndrome
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. |
