Clinical Trials

Inclusion Criteria:

• Participants will meet inclusion criteria if they live in the community.
• Aged 18 or older, male or female, have paraplegia or quadriplegia due to a spinal cord injury that includes sensory loss below their level of injury, and require full-time wheelchair use for mobility.
• Participants must demonstrate ability to independently access a smartphone and the required pressure mapping application on the smartphone. 
• Participants must be able to tolerate sitting for a minimum of 6 hours per day, 7 days per week, and they must be able to perform weight shifts independently.
• Participants must be able and willing to attend in-person visits at start and end of the study, about 4 weeks apart.

Exclusion Criteria:

• Individuals will not be eligible for this study if there is an active stage 3, 4, or unstageable pressure ulcer as defined by the National Pressure Ulcer Advisory Panel definitions anywhere on their sitting surface.
• They are not able to independently access the pressure mapping application on a smartphone, or if they are not able to complete an adequate weight shift without help.
• Individual who use a specific custom-molded seat cushion (Ride Designs Custom Seat Cushion) will not be eligible due to challenges with conformability of the pressure sensing mat to the deep contours of this particular cushion. 
• Individuals will also be excluded if they live in a long term care facility or group home and require 24 hours/day assistance.
• Participants will be screened by phone or in person when being considered for enrollment into the study for cognitive impairments relating to memory and new learning. If a cognitive impairment is identified by a score of 3 or less on the Six-item Screen for Cognitive Impairment (Callahan, Unverzagt, Hui, Perkins, & Hendrie, 2002), the participants will not be able to participate in this study because there is an expectation of ability to learn new information and be able to recall the information over the study period.
• Participants must be Mayo Clinic patients for access to the medical record.
