Study Design:
Invited literature review BACKGROUND: Arthritis is the leading cause of disability in adults, and research shows that people living with arthritis experience work instability, loss of independence, financial difficulties, and overall decreased quality of life. Current nonpharmacological treatments can be beneficial for short term relief; however, the evidence on these long-term treatments is limited. Ergonomic modifications have been used in the workplace to address musculoskeletal conditions to ensure proper fit of one's environment, and research shows that these modifications can decrease pain and injury and increase work productivity. A broader perspective on ergonomic approaches may be important to supporting individuals with arthritis within hand therapy.
Purpose Of The Study:
This review proposes an expanded perspective on ergonomic approaches within hand therapy and explores published literature to identify potential benefits of applying ergonomic approaches for individuals with upper extremity arthritis.
Methods:
A systematic search and screening process was conducted to identify articles that implemented an ergonomic approach for the support of individuals with upper extremity osteoarthritis or rheumatoid arthritis.
Results:
A total of 34 articles described interventions that employed ergonomics including task-based or general ergonomics (n = 17), contextualized supports (n = 8), or holistic, lifestyle approaches (n = 9). Only one study focused solely on individuals with osteoarthritis, whereas interventions for individuals with rheumatoid arthritis showed positive outcomes across these categories. Situational learning, building of patient self-efficacy, and development of new habits and routines are vital for carryover and implementation to support performance in daily life.
Conclusion:
There is an opportunity for hand therapists to extend the scope of interventions provided as part of an ergonomic approach to supporting patients. Specifically, therapists can consider use of emerging technologies and telehealth that promote contextualization and follow-up for long-term outcomes.
