Details and patient eligibility
About
The purpose of this randomized control study is to evaluate the use of electric powered wheelchairs and powered seating function patterns of Veterans to determine how usage patterns relate to activity, participation, and seating discomfort. In addition, it will be determined if a training program or a training program with a virtual coach will improve compliance of clinical practice guidelines for pressure relief, upper limb preservation, and discomfort management. The virtual coach is a portable, programmable intelligent reminder designed to enhance a person's use of their power wheelchair and power seat functions.
Full description
This is a randomized control trial evaluating power seat function usage among 3 groups: 1) standard of care- verbal instruction 2) verbal and written instruction and 3) same as #2 with addition of virtual coach. This study will be conducted in two phases. Phase I data will be collected for 8 weeks, during the time period that the subject is awaiting for delivery of their personal electric powered wheelchair (EPW) with powered seat functions. Phase II data will be collected for a total of 4 weeks, after the subject receives their personal wheelchair. During Phase I, Visit I, subjects will be fitted for a study EPW with powered seat functions. All subjects will be provided with the "standard of care" training on driving of the wheelchair and usage of the power seating functions. Subjects will be instructed to go about their daily activities as they normally would, while the instrumented wheelchair will track their usage of the wheelchair and seating habits. Phase I, Visit II-IV, subjects will be randomized into one of three study groups: Control Group; Instruction Group; and Instruction & Virtual Coach Group. Subjects assigned to the Control Group will receive 'standard of care.' Subjects assigned to the Intervention Group will receive the "standard of care" and additional written instructional materials and feedback regarding activity and wheelchair usage. Subjects assigned to the Instruction & Virtual Coach Group will receive the same training and instructional materials as the Intervention Group. This group will also be instructed in use of the virtual coach system, which will be active during the in-home usage periods to provide personalized feedback. Phase II will involve mounting a wheelchair and seat function usage datalogger to the subject's personal wheelchair over a period of 4 weeks.
