Effectiveness of Thermoplastic vs Fabricated Orthoses for Female Adults with Boutonniere Thumb Deformity and Rheumatoid Arthritis

What this Trial Is About

This research aims to evaluate the effectiveness of a specially designed thermoplastic thumb orthosis compared with factory-made fabric orthoses in women with rheumatoid arthritis and boutonniere deformity of the thumb. The study will assess how these devices impact hand function, strength, dexterity, and pain levels over time. About 60 female participants aged 18 to 65 years will be included, with half using the thermoplastic orthosis and half using the factory-made version. Participants will be randomly assigned to wear either the thermoplastic or fabric orthosis. The thermoplastic device is designed to correct the alignment of the thumb joints by properly tensioning the extensor bands, aiming to improve hand mobility, grip strength, and reduce pain. Both groups will be monitored for changes in grip strength, pincer grip strength, pain levels, hand function, and satisfaction with the orthosis over a six-month period. During the study, participants will undergo regular measurements of grip and pincer strength using a hydraulic handgrip dynamometer, complete the Disabilities of the Arm, Shoulder and Hand DASH questionnaire to assess upper limb disability, rate their pain on a numerical scale, and evaluate thumb opposition using the Kapandji score. Satisfaction with the orthosis will also be assessed using a Likert scale. Researchers will compare the results between the two groups to determine which orthosis offers better function and pain relief.
