摘要

Achilles tendinopathy is a common musculoskeletal condition characterised by pain and functional impairment. Current treatments, such as eccentric exercises, are recommended as first-line options, but their success rates are often disappointing. Adjunctive novel treatments may help improve outcomes for these patients. This study aims to determine whether participants receiving active pulsed electromagnetic field (PEMF) therapy combined with eccentric exercise experience sustained additional improvements compared to those receiving sham PEMF therapy combined with eccentric exercise. A total of 65 participants were recruited and randomly assigned to an 8-week programme of either active PEMF therapy or sham PEMF therapy. Additionally, all participants completed a standardised home-based eccentric exercise programme for 12 weeks. The Victorian Institute of Sport Assessment questionnaire was the primary outcome. The Numeric Pain Rating Scale and the Short Form 36 were selected as the secondary outcomes. An eight-week PEMF therapy, conducted alongside a twelve-week eccentric exercise regimen, resulted in notable improvements for both treatment groups across all outcomes. These improvements were maintained at the twenty-six-week follow-up. PEMF therapy constitutes an innovative, non-invasive therapeutic approach that shows potential for treating Achilles tendinopathy. Additional research into the optimal dosage of PEMF therapy is recommended to develop thorough future clinical trials.
