Objective: Systemic sclerosis (SSc) is characterized by significant disability because of musculoskeletal involvement. Physical and occupational therapy (PT/OT) have been suggested to improve function. However, the rate of PT/OT use has been shown to be low in SSc. We aimed to identify demographic, medical, and psychological variables associated with PT/OT use in SSc.
Methods: Participants were patients with SSc enrolled in the Scleroderma Patient-centered Intervention Network (SPIN) Cohort. We determined the rate and indication of PT/OT use in the 3 months prior to enrollment. Multivariable logistic regression was used to identify variables independently associated with PT/OT use.
Results: Of the 1627 patients with SSc included in the analysis, 23% used PT/OT in the preceding 3 months. PT/OT use was independently associated with higher education (OR 1.08, 95% CI 1.04-1.12), having moderately severe small joint contractures (OR 2.09, 95% CI 1.45-3.03), severe large joint contractures (OR 2.33, 95% CI 1.14-4.74), fewer digital ulcerations (OR 0.70, 95% CI 0.51-0.95), and higher disability (OR 1.54, 95% CI 1.18-2.02) and pain scores (OR 1.04, 95% CI 1.02-1.06). The highest rate of PT/OT use was reported in France (43%) and the lowest, in the United States (17%).
Conclusion: Despite the potential of PT/OT interventions to improve function, < 1 in 4 patients with SSc enrolled in a large international cohort used PT/OT services in the last 3 months. Patients who used PT/OT had more severe musculoskeletal manifestations and higher pain and disability.
