Pulsed Electro-Magnetic Field Therapy for Treatment of Midportion Achilles Tendinopathy

Recruiting now · Not applicable · Has a placebo group

Conditions studied: Mid-portion Achilles Tendinopathy

In brief

This is a multi-centre, randomised, double-blind, placebo-controlled trial with two parallel groups in a 1:1 allocation to study the efficacy of Pulsed Electromagnetic Field Therapy (PEMF) in patients with mid-portion Achilles tendinopathy. All participants will be randomly divided into two groups: an intervention group (active PEMF and standard rehabilitation exercise) and a control group (sham PEMF and standard rehabilitation exercise). All self-reported, functional, and ultrasound findings will be evaluated by the investigator at baseline assessment, 1-month, 2-month, 3-month, 6-month and 12-month follow-up after initiating the intervention. The researcher will obtain written consent from all participants before the start of this study. All eligible participants will be informed about this study and given enough time to consider whether or not to participate; the clinician/research staff will answer all questions asked by the participants. The trial will be conducted in accordance with the Declaration of Helsinki and the ICH-GCP. Clinical research ethics approval for the trial will be obtained from the Joint Clinical Research Ethics Committee of The Chinese University of Hong Kong. All participants will be recruited from the clinics and centres of the participating institutions.
