A new orthosis for finger joint stiffness

A Novel Shape Memory Alloy-Based Orthosis for Proximal Interphalangeal Joint Stiffness

Not applicable Interventional National Cheng-Kung University Hospital · NCT06716086

This study is testing a new type of finger brace to see if it helps people with stiff finger joints move better compared to a regular stretching program.

What this trial studies

This clinical trial evaluates the effectiveness and usability of a shape memory alloy-based orthosis designed for patients suffering from stiffness in the proximal interphalangeal joint of the fingers. Participants will be divided into two groups: one receiving the innovative orthosis for home use and the other following a conventional stretching program. The study will assess improvements in range of motion and hand function through evaluations conducted before the intervention and at 4 and 8 weeks post-baseline.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-79 with limited passive range of motion in the proximal interphalangeal joint due to past injuries or surgeries.

Not a fit: Patients with concurrent splint use, neurological disorders, or active infections affecting their fingers may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve finger mobility and functionality for patients with joint stiffness.

How similar studies have performed: While the use of shape memory alloys in orthotic devices is innovative, similar studies have shown promise in improving joint function with advanced materials.
