The investigators propose to test the feasibility of iSHIFTup (Internet Skin Health Intervention For Targeted Ulcer Prevention) for adults with spinal cord injury (SCI) to prevent serious pressure ulcers (PrUs) and promote protective health behaviors. This protocol is Phase 2 of a three phase project. In Phase 1, the investigators developed iSHIFTup. In Phase 2, the investigators will test the intervention by partnering with Woodrow Wilson Rehabilitation Center (WWRC) to conduct a randomized controlled trial (RCT) of 18 participants. In Phase 3, the investigators will focus on optimizing the intervention based on our outcome findings and feedback, sustaining the program at WWRC, and seeking future funding for a larger RCT.
