A systematic review of the benefits of occupation-based intervention for patients with upper extremity musculoskeletal disorders

Abstract Study Design Systematic review of intervention studies (level 3a). Introduction Occupation-based intervention (OBI) uses daily activities as a treatment modality. Its growing use with patients diagnosed with upper extremity musculoskeletal disorders (UE MSK) has driven interest in its supporting body of evidence. Purpose of the Study The purpose of this study was to locate, appraise, and summarize current evidence of the effectiveness of OBI in treating patients with UE MSK. Methods Searches of PubMed, CINAHL, the Cochrane Register for Controlled Trials, and PEDro databases were conducted using predetermined keywords. Studies included in this systematic review described the use of OBI in UE MSK. Two examiners independently reviewed and assessed the quality of each study using the PEDro scale. Results Results of the database searches yielded 991 studies, 13 of which were deemed eligible to include in this review (6 randomized controlled trials, 4 pretreatment/post-treatment cohort or case series studies, and 3 single case reports). Quality of the studies varied, with 4 rated poor, 2 moderate, and 4 excellent. Overall, individuals receiving OBI showed superior benefits in patient-reported, performance, and physical measures assessing the upper extremity. Discussion Findings of this review provide preliminary evidence for the use of OBI with patients with UE MSK, however, generalizability of the evidence was compromised due to heterogeneity in study subjects as well as conceptualization, dosage, and delivery of OBI. Conclusions The existing literature reflects promising trends in the use of OBI, underscoring its utility as a treatment option for UE MSK-related impairment, limitations, and restrictions. Nonetheless, scientific evidence concerning the effectiveness of OBI needs to be improved by conducting high-quality studies that clearly conceptualize this intervention and heighten understanding of its role in hand therapy practice.
