Abstract
Pain is the main symptom of inflammatory arthritis and it can impair physical functional performance and physical activity level. Some individuals can develop kinesiophobia and experience a vicious circle of worsening health. This study aimed to investigate the association between pain and physical functional performance/physical activity and determine whether kinesiophobia mediates this association. This was a cross-sectional study with individuals diagnosed with inflammatory arthritis (rheumatoid arthritis or spondyloarthritis) treated at a Rheumatology Outpatient Clinic. We assessed pain (Visual Analogue Scale), physical activity (International Physical Activity Questionnaire - long form), kinesiophobia (Tampa Scale for Kinesiophobia), and physical functional performance (Handgrip Strength Dynamometry, 30-second Sit-to-Stand test, Static Muscular Endurance test, and Timed Up and Go test). The mediating effect of kinesiophobia on the relationship between pain intensity and physical functional performance/physical activity was analyzed, and the significance of the mediating effect (kinesiophobia) was tested through a bootstrap approach. Thirty-three individuals with inflammatory arthritis (mean age: 48 ± 12 years) participated in the study. Kinesiophobia mediates the relationship between pain intensity and physical functional performance analyzed by the 30-second Sit-to-Stand test [indirect effect (IE)overall = -0.343, bootstrap 95% confidence interval (CI): -0.698 to -0.002] and by knee flexion at 90º of the dominant limb (IEoverall = -1.55, bootstrap 95% CI: -3.43 to -0.237). In conclusion, pain intensity can affect physical functional performance through kinesiophobia in individuals with inflammatory arthritis.
期刊介绍:
International Journal of Rehabilitation Research is a quarterly, peer-reviewed, interdisciplinary forum for the publication of research into functioning, disability and contextual factors experienced by persons of all ages in both developed and developing societies. The wealth of information offered makes the journal a valuable resource for researchers, practitioners, and administrators in such fields as rehabilitation medicine, outcome measurement nursing, social and vocational rehabilitation/case management, return to work, special education, social policy, social work and social welfare, sociology, psychology, psychiatry assistive technology and environmental factors/disability. Areas of interest include functioning and disablement throughout the life cycle; rehabilitation programmes for persons with physical, sensory, mental and developmental disabilities; measurement of functioning and disability; special education and vocational rehabilitation; equipment access and transportation; information technology; independent living; consumer, legal, economic and sociopolitical aspects of functioning, disability and contextual factors.
