OBJECTIVE: Patients with rheumatic disease often experience arthritis and chronic joint pain, which can lead them to avoid movement, known as kinesiophobia. This may result in decreased mobility and endurance, as well as social isolation and depression. This study aimed to assess and compare the prevalence of kinesiophobia among patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), and its association with disease activity, functional status, fear of falling, and fatigue.

PATIENTS AND METHODS: A cross-sectional study was conducted with 124 RA, 76 SLE patients, and 87 healthy controls. The tampa kinesiophobia scale (TKS) was used to assess kinesiophobia. The disease activity was assessed using Disease Activity Score 28 (DAS28) in RA, and systemic lupus erythematosus Disease Activity Index 2000 (SLEDAI-2K) in SLE patients. The Health Assessment Questionnaire (HAQ) was used to assess functional status, the Falls Efficacy Scale International (FES-I) was used to assess fear of falling, and the Fatigue Severity Scale (FSS) was used to assess fatigue levels.

RESULTS: Kinesiophobia was significantly more prevalent in RA patients compared to SLE patients [77.4% vs. 63.2%, odds ratio (OR): 2, 95% CI: 1.07-3.75; p<0.05]. The mean TKS score was 41.42±6.95 in RA patients, and 37.84±8.85 in SLE (p=0.005). TKS scores were positively correlated with DAS28 in RA patients; however, no correlation was found between SLEDAI-2K in SLE patients. A positive correlation was observed between TKS scores and the HAQ, FSS, and FES-I, both in RA and SLE patients.

CONCLUSIONS: RA patients exhibited significantly higher kinesiophobia scores compared to SLE patients. The higher rate of kinesiophobia levels in RA patients compared to SLE patients suggests an association between kinesiophobia and the more destructive course of RA, indicating that tight control of the disease is important. Kinesiophobia was associated with functional impairment, fear of falling, and fatigue. Timely identification and intervention for patients with kinesiophobia are essential to prevent progression, mitigate long-term consequences, and maintain functional capacity.
