The Role of Home-Based Exercise in Managing Common Musculoskeletal Disorders: A Narrative Review

Background: Physical exercise can improve certain musculoskeletal conditions, but adherence remains low due to intimidating environments, limited government support, and financial constraints faced by many individuals. Home-based exercise is a potential strategy to treat that population. Objective: Discuss the main home-based resistance exercise protocols that have been studied and implemented for six highly prevalent musculoskeletal disorders. Methods: A narrative literature review was conducted, using the PubMed database to search for six highly prevalent musculoskeletal conditions: shoulder impingement syndrome (SIS), nonspecific low back pain (NSLBP), greater trochanteric pain syndrome (GTPS), knee osteoarthritis (OA), patellofemoral pain syndrome (PFPS), and Achilles tendinopathy (AT). The strategy included the listed pathologies and the keywords "physical exercise" or "physiotherapy". Clinical trials, reviews, and retrospective studies from the last 30 years published in English, Portuguese, or Spanish were included. Only studies with sufficient details on the training protocols used and outcome measures were included in the analysis. Results: In SIS, exercise protocols have been more effective in the long term than in the short term. In PFPS and GTPS, strengthening the quadriceps and hip muscles helps reduce pain and improve function. For NSLBP, exercises like Pilates and core training demonstrate pain relief. In knee osteoarthritis, physical exercise improves pain, function, and quality of life both immediately and over time. Eccentric training promotes type I collagen formation in the tendons of patients with Achilles tendinopathy. Conclusions: Home-based resistance exercises studied and implemented in this review offer several general health benefits, including pain reduction, improved functionality, increased muscle strength, and enhanced motor control.
