The Impact of Kinesiophobia on Pain, Physical Activity, and Quality of Life Among People with Knee Osteoarthritis: A Systematic Review
Abstract
Objective: Knee osteoarthritis is a prevalent musculoskeletal disorder that leads to pain, reduced physical activity, and impaired quality of life, particularly among older adults. Kinesiophobia, or fear of movement, is an important psychological factor that may influence these outcomes. This systematic review aimed to investigate the impact of kinesiophobia on pain, physical activity, and quality of life in individuals with knee osteoarthritis. Methods: A systematic search of electronic databases including PubMed (Medline), Scopus, CINAHL, Web of Science, ResearchGate, and Google Scholar was conducted for studies published between January 2015 and January 2023. Studies were selected based on predefined inclusion and exclusion criteria. Risk of bias was assessed using the Robvis tool. Results: A total of 3880 articles were identified, of which 3130 duplicates were removed. After screening titles, abstracts, and full texts, 13 studies met the eligibility criteria. The findings indicated no consistent statistically significant correlation between pain intensity and Kinesiophobia. However, Kinesiophobia demonstrated a significant negative influence on physical function and activity levels. Reduced physical activity, along with the presence of kinesiophobia and depressive symptoms, was associated with poorer quality of life and increased disability. Conclusion: Kinesiophobia plays a significant role in limiting physical activity and functional performance, thereby contributing to disability and reduced quality of life in individuals with knee osteoarthritis. Addressing fear of movement and pain-related beliefs should be an integral component of rehabilitation strategies to improve patient outcomes. Major Findings: Kinesiophobia was not consistently associated with pain intensity but was significantly associated with reduced physical activity and functional performance in individuals with knee osteoarthritis. Higher kinesiophobia, reduced activity, and depressive symptoms were associated with greater disability and poorer quality of life.
