Clinical Trial Summary

During typical daily activity, people with established spinal cord injury perform significantly fewer pressure-relief maneuvers than the recommended frequency while overestimating their adherence on recall surveys of pressure relief activity. The rate of pressure ulcer recurrence in individuals with a prior ulcer is 44% in those with surgical repair and as high as 75% in those with non-surgical healing indicating that increased attention to pressure relief is critical for these individuals.This study will evaluate the efficacy of a wheelchair sensor and app-based biofeedback for establishing healthy self-management behaviors (pressure relief maneuvers and daily physical activity). Investigators will enroll 50 participants with paraplegia from spinal cord injury who use a manual wheelchair for mobility and have a history of pressure ulcer that has healed or is six months post-surgical repair. Participants will be randomized into one of two groups: an intervention group that will receive an education intervention and the proposed technology to be used for one year, and a control group that will receive only the education intervention. The primary outcome will be pressure ulcer occurrence over one year. Investigators hypothesize that participants receiving the intervention of biofeedback on their pressure relief activity will have a lower recurrence of pressure ulcer than the education only control group. Secondary outcomes include depressive symptoms, self-efficacy, participation and satisfaction with life. Investigators hypothesize that increasing physical activity will reduce depressive symptoms and improve participation and satisfaction with life.

Description:

Purpose: The purpose of this study is to evaluate the efficacy of an interactive tele-health monitoring and biofeedback system to establish healthy behaviors and promote self-management of pressure relief maneuvers and physical activity.

Procedures and Course of Study:

Baseline 50 participants will be enrolled. At study entry participants will complete four baseline questionnaires and have a Nurse Practitioner or Physician's Assistant inspect their ischial skin to ensure that their prior ulcer is fully healed. A pressure-sensing mat (PRESS) will be placed under their wheelchair cushion, and a wheelchair propulsion motion sensor (WAMS) will be placed on the rear wheel of their wheelchair. The PRESS and WAMS sensors will record participants' pressure relief and wheelchair propulsion activity for the next two weeks.

Intervention:

Participants will then return to the clinic and the study physical therapist will provide all participants with education on importance of pressure relief maneuvers and physical activity for health as well as training in the 3 styles of pressure relief (forward and side leans, depression raise) and shoulder strengthening exercises to protect against shoulder impingement and pain with increased pressure relief and wheelchair propulsion activity. The study physical therapist will then assist all participants in setting goals to increase pressure relief frequency and/or duration and wheelchair propulsion pushes for the future based on their baseline activity. Participants will be randomized into one of two groups: feedback and no feedback. In both groups pressure relief and wheelchair propulsion activity will be recorded by the PRESS and WAMS sensors for the 12 months. Those participants in the no-feedback group will have the feedback features of the system disabled. Those participants in the feedback group will receive instant visual feedback on pressure relief duration and daily summary charts for both pressure relief and wheelchair propulsion activities.

Follow-up:

Every month following the intervention for 12 months, a physical therapist will contact participants by phone to inquire whether their ischial skin integrity has changed and whether they have developed a pressure ulcer. Additionally, all participants will return to the clinic at 3, 6, 9, and 12 months after the intervention and a nurse practitioner will examine their ischial skin and review their medical records to determine if a pressure ulcer has developed. Participants will repeat the 4 questionnaires from the baseline evaluation at each follow-up visit. At the 12 month follow-up visit, participants will return the sensor equipment.
