To describe the usage of functional wrist orthoses and to identify factors contributing to usage in patients with rheumatoid arthritis (RA).
A multicentre, cross-sectional study, including a random selection of patients with RA visiting outpatient clinics. A total of 240/362 eligible patients (66%) completed questionnaires, a semi-structured interview and a clinical assessment. Usage was registered according to eight categories ranging from 'always' to 'never'. Factors potentially associated with usage included demographic variables, the presence of wrist and hand complaints, general disease characteristics, mental and physical functioning, coping strategies and satisfaction with functional wrist orthoses. Logistic regression analyses were used to determine which factors were associated with the usage of wrist splints.
One hundred twenty-eight patients (53%) possessed functional wrist orthoses, whereas 74/128 (58%) were actually using them. Patients used them mainly during house keeping and cycling/driving. Main reasons for using the orthoses were relief of pain and joint protection, and main reasons for not using them were no need and problems with ease of use. Factors significantly associated with usage included the presence of wrist and hand complaints, worse physical functioning and greater satisfaction with comfort of the wrist orthoses.
About half of patients with RA possessed functional wrist orthoses, with 58% of them actually being used. Apart from local complaints and general functional ability, satisfaction with comfort of the functional wrist orthoses appears to be an important factor for their usage. These results point at the need for additional research regarding modifiable factors associated with compliance, such as comfort and ease of use.
