Brief Summary

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.

Detailed Description

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.

Study & Design

INTERVENTIONAL

Arm && Interventions
GroupInterventionDescription
3D model splinting intervention groupCustom Fabricated SplintThe researcher will scan the participant's forearm, wrist, and hand with an iPhone camera through the Comb O\&P Scan App. Scans will be completed individually to maintain privacy. The entire Comb O\&P platform is HIPAA compliant. The data is de-identified encrypted when it moves from the iPhone app to the computer through the cloud. Precision Valve Automation (PVA) will use the de-identified scans to print the 3D models which are a precise replica of the participant's hand. Once the researcher obtains the 3D models, resting hand splints will be fabricated on the 3D models to provide custom-made hand splint(s) to each participant. The participants will receive the splint(s) to wear during the hours of sleep for six weeks.
Primary Outcome Measures
NameTimeMethod
Change in range of motion of the hand (measured with a goniometer)Every other week throughout the intervention period, a total of three times during the intervention which is six weeks long.

The active range of motion of the participant's affected forearm, wrist, and fingers will be assessed with a goniometer. A change in range of motion across the six week intervention period will be assessed.

Secondary Outcome Measures
NameTimeMethod
Change of reported comfort level (in hand) measured through a surveyDaily throughout the six week intervention period

Patients will report their perceived comfort level in their hand each morning after wearing the splint in an online or hard copy questionnaire. The scale is 0-10. 0 being least uncomfortable to 10 being very comfortable. The change in comfort in the hand across the six week intervention period is being assessed.

Change in hours of sleep measured through a surveyDaily throughout the six week intervention period

Participants will log their hours of sleep and hours they wear their splint each night to determine if they are able to sleep longer when wearing the splint compared to before they wore the splint. This data will be tracked to ensure the intervention is not decreasing hours of sleep significantly. The change in hours of sleep across the six-week intervention period will be assessed.

Disability of the Arm, Shoulder, and Hand QuestionnaireOne time within a week of completing the six week intervention

Self-administered outcome instrument developed as a measure of self-rated upper-extremity disability and symptoms. The DASH consists mainly of a 30-item disability/symptom scale, scored 0 (no disability) to 100. This will be used to assess the participant's ability to complete occupation based tasks with their affected hand.

Number of patients with intact skin integrity of the hands through photographsPhotographs of the hand will be taken one day before the six week intervention begins

Photographs of the wrist and hand will be taken to assess the skin integrity of the hand that is wearing the splint. Intact skin integrity is indicated by the absence of ulcers, sores, and redness.

Patient satisfaction with splinting process - Individual InterviewWithin a week of completing the six week intervention, the participants will be interviewed

The participants will complete a brief 15 minute interview to assess their overall satisfaction with the novel splinting method and splinting intervention. The interview will occur via Zoom or phone call. The participant will answer the following questions:

How do you feel the splint intervention went? 2. What would you have wished would have been different throughout this process? 3. Do you feel as though this process was beneficial for you?

Change in the number of patients with intact skin integrity of the hands through photographsEvery other week throughout the intervention period, a total of three times during the intervention which is six weeks long.

Photographs of the wrist and hand will be taken to assess the skin integrity of the hand that is wearing the splint. Intact skin integrity is indicated by the absence of ulcers, sores, and redness.
