Summary
This study evaluated an online hand exercise program for scleroderma patients. While the program was feasible, low acceptance and usage rates suggest a need for improved participant engagement strategies.
Area of Science:
- Rheumatology and Digital Health
- Patient-centered intervention development
- Feasibility studies in clinical trials
Background:
- Scleroderma often impairs hand function, necessitating accessible interventions.
- Online self-help programs offer a scalable solution for managing chronic conditions.
- The Scleroderma Patient-centered Intervention Network (SPIN) developed an online hand exercise program (SPIN-HAND).
Purpose of the Study:
- To assess the feasibility of a full-scale randomized controlled trial for the SPIN-HAND program.
- To evaluate participant acceptance and usage of an online hand exercise intervention for scleroderma.
- To refine recruitment and engagement strategies for digital health interventions in rheumatology.
Main Methods:
- A feasibility trial using a cohort multiple randomized controlled trial (cmRCT) design.
- Participants with scleroderma and hand dysfunction (Cochin Hand Function Scale score ≥ 3/90) were randomized (1:1) to usual care plus SPIN-HAND or usual care.
- User satisfaction was assessed via semi-structured interviews.
Main Results:
- Of 40 randomized participants, 24 were offered SPIN-HAND, with 15 (63%) consenting to use it.
- Low engagement was observed, with only 5 (33%) of those who consented logging in more than twice.
- Participants who used the program reported high satisfaction (8.5/10) with content relevance and ease of understanding.
Conclusions:
- The SPIN-HAND program's trial methodology was feasible and delivery was successful.
- Low offer acceptance and program usage among participants present challenges for full-scale implementation.
- Future trials will adjust information provided to potential participants to enhance offer acceptance and engagement.
