Digital versus in-person physical therapy for osteoarthritis pain and function
摘要
Osteoarthritis (OA) is the leading cause of chronic joint pain worldwide, yet access to guideline-recommended face-to-face physical therapy remains limited for many patients. This systematic review and meta-analysis compared interactive, therapist-guided internet-based digital health interventions with supervised in-person physical therapy for adults with clinical or radiographic OA. MEDLINE, EMBASE, CINAHL, AMED, and trial registries were searched through March 31, 2025, for randomized controlled trials. Fourteen RCTs involving 1730 participants were included, comprising 10 knee OA studies, 2 mixed-joint studies, 1 hip OA study, and 1 hand OA study. Digital interventions produced a statistically significant but clinically trivial reduction in WOMAC Pain (MD −0.55, 95% CI −0.91 to −0.19; I² = 0%). NRS (MD −0.79, 95% CI −1.35 to −0.23; I² = 89%) and VAS pain outcomes (MD −7.39, 95% CI −14.45 to −0.33; I² = 86%) also favored digital care, although heterogeneity and risk of bias were substantial. WOMAC Function improved with digital programs (MD −1.61, 95% CI −2.44 to −0.79; I² = 68%), while adherence was comparable. Overall, digital interventions appear comparable to face-to-face physical therapy for short-term OA pain and function, but evidence certainty remains limited.
