Abstract
This randomized, double-blind, placebo-controlled clinical trial investigated the therapeutic efficacy of pulsed electromagnetic field (PEMF) therapy in dogs diagnosed with chronic osteoarthritis (OA).
Twenty-one dogs with radiographically confirmed OA in at least one limb were randomized into treatment (n = 10) and placebo (n = 11) groups. PEMF therapy was administered over six weeks. Gait symmetry indices for peak vertical force and vertical impulse were assessed using kinetic analysis at baseline (Day 0), mid-treatment (Day 21), and post-treatment (Day 42). Lameness and pain scores, additional treatments, and dropout rates were recorded. Owners completed the Liverpool Osteoarthritis in Dogs (LOAD) questionnaire at each time point. An Overall Treatment Effectiveness (OTE) score was computed based on objective and subjective outcomes.
PEMF-treated dogs exhibited significant improvements in gait symmetry by Day 42 (p = 0.030). LOAD scores declined steadily in the treatment group, although no statistically significant differences were observed between groups. This trend may suggest a potential reduction in pain and improvement in mobility. No significant between-group differences were found for the OTE score.
PEMF therapy appears to be a safe, non-invasive, and potentially effective adjunctive or stand-alone modality for the management of pain and mobility impairment associated with osteoarthritis in dogs. Further research is warranted to confirm long-term efficacy and optimize treatment protocols.
