Novel Splinting Technique Using 3D Models

The purpose of the study is to determine the feasibility of a non-contact custom splint fabrication method for patients with chronic diseases suffering from hypersensitive skin or compromised skin integrity. Custom splinting by occupational therapists involves molding low-temperature thermoplastic material directly on patients' skin; however, skin sensitivity is a contraindication for splint fabrication. The study aims to recruit 10 male or female patients with either a diagnosis of scleroderma (SSc) or arthritis. A scan of the patient's hand and a 3D printer will be used to create a precise model of a patient's hand on which a custom splint will be fabricated. By taking this approach, traditional splinting is substituted by avoiding direct contact with the material on the surface of the patient's upper extremity. This technique creates therapeutic opportunities for underserved patients by expanding splinting options for patients with scleroderma and arthritis, and addressing the challenges associated with managing chronic diseases.

Arthritis is an inflammatory disease that occurs in the joints of the body. Scleroderma is a disease of the autoimmune system in which the body produces excess collagen in the skin and organs. Depending upon a patient's needs, occupational therapists (OTs) make custom hand splints to support individual goals and promote independence. Conventional splinting methods involve molding low-temperature thermoplastic material directly on a patients' skin; however, many chronic diseases including arthritis and scleroderma carry a predisposition for skin sensitivity or compromised skin integrity, leaving these populations with no alternative. The study will recruit 10 male or female patients with either a diagnosis of arthritis or scleroderma for a 14-week study. Researchers will use a scanner and 3D printer to create a model of a patient's hand prior to splinting, which will allow therapists to custom-fit the 105-degree splinting material on the model. Traditional splinting is substituted by avoiding fabricating the splint directly on the patient's hand and providing the opportunity for patients with hypersensitive skin to benefit from a custom-made splint. Implementing this technique creates opportunities by expanding splinting options for patients with chronic diseases. The goals of this study are to evaluate effectiveness, support positive engagement in daily activities, improve patient outcomes, and promote best practice. The research will also establish a foundation for future studies with custom splinting using 3D printed material.
