The Clinical Effectiveness of Pulsed Electromagnetic Field Therapy on the Management of Chronic Ankle Instability: A Double-Blinded Randomized Controlled Trial
Abstract
This study aims to investigate the clinical effectiveness of PEMF as an adjunct to a program of standard rehabilitation for the treatment of chronic ankle instability. The study objective is to establish whether PEMF plus standard rehabilitation in people with chronic ankle instability compared to standard rehabilitation. This study also investigates the effects of PEMF on pain, functional outcomes, and mechanical and morphological properties of peroneal muscles in chronic ankle instability. Investigators hypothesize that pulsed electromagnetic field therapy is effective in reducing pain, improving functional outcomes, and restoring mechanical and morphological properties.
This study is a double-blinded, randomized controlled trial to investigate the clinical effects of pulsed electromagnetic field therapy (PEMF) for chronic ankle instability. Participants will be recruited from the outpatient clinic of the orthopedic and traumatology department at Prince of Wales Hospital.
40 patients aged between 18 to 60 years old with CAI will be invited to join this trial after informed consent. Participants will be randomized to any of the 2 groups: the intervention group (n=20; PEMF (Quantum Tx) treatment), and the control group (n=20; sham treatment with dummy exposure to PEMF).
For Chronic Ankle Instability patients: baseline measurements of all self-reported outcomes, functional outcomes, and ultrasound imaging assessments, such as dynamic balance, static balance, single leg hop…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 62 participants or records.
