Millions of people struggle with the sit-to-stand motion. Transferring between sit and stand is a frequently performed daily task. Among the activities requiring this transferring movement, getting on and off the toilet is one of the most essential. Currently, the solution is to install taller toilets with handrails. These solutions create stigma and have great cost implications. This product must assists users with toilet transferring, is assembled easily and works compatibly with the existing toilet. Prototypes have been created and tested.
Erythema and Bruise Detector
This Point of Care technology is being designed for people who require non-contact and simple assessment of bruises, erythema and Stage I pressure ulcers. The many potential users include nurses, podiatrists, prothetists, social workers home health professionals, physicians and therapists. This device has potential application in the fields of forensics, abuse, geriatrics, nursing, and pressure ulcer prevention. See the fact sheet for the Erythema and Bruise Detector here
The purpose of this project is to support inventor and small company development of promising mobility-related technologies. Need for such support has been demonstrated within the current mobility RERC and is consistent with conclusions from the Department of Commerce report. The project is designed to formalize engagement of inventors/small companies. There is an established process through which the mobility RERC provides a basic level of support and guidance as well as more advanced development and testing to those with promising mobility products. Specifically, the process includes: 1) an informal brainstorming session addressing technical, market and user issues; 2) formal screening of device potential and RERC capacity to assist in development; 3) invitation to engage inventors/companies with promising technologies; and 4) product testing and/or development of promising technologies.
This effort has resulted in significant outcomes. The KISS System created a way to standardize wound measurement. Quantum Rehab released the Synergy Air Cushion with its base material from Sil-Air Spectrum Air. Another small business, PostureWorks has licensed Sil-Air technology for use in nursing homes.
The overall purpose of this project was to design manual wheelchair technology that can meetthe unique needs of aging users across the continuum of residential environments whileaddressing the needs of family caregivers and facility staff.

Portable Pediatric Therapy Stairs
Tissue Interrogation Device
Many medical conditions impact the mechanical properties of tissue. Measuring and monitoring tissue properties can be both challenging and difficult, especially within different care environments. A method for directly measuring tissue stiffness and viscosity would advance clinical diagnosis and tracking of pathological conditions. Some devices exist which estimate tissue stiffness or Young’s modulus, but these methods result in qualitative descriptions of these properties, and can be cumbersome and difficult to use. As a result, they have not gained wide clinical acceptance.

This study addresses a defined area of encouragement and targets the prevention of pressure ulcers. The prevalence of PrUs remains substantial. More than 50% of people with spinal cord injuries (SCI) will experience a PrU after injury, with over 20% requiring surgery. This project seeks to design a commercially-viable system to inform wheelchair users about their weight-shifting activity as a means to promote healthy behaviors and prevent pressure ulcers. Termed the WiSAT (Wheelchair In-seat Activity Tracker), it will have impact on wheelchair users, their clinicians and researchers. Such a product can empower wheelchair users with knowledge about their behaviors associated with PrU prevention. The WiSAT’s impact will extend beyond wheelchair users by also meeting the needs of clinicians and researchers. During rehabilitation interventions, clinicians educate persons SCI about PrU prevention. One aspect of this education is the training of a pressure-relief regimen that seeks to regularly shift weight off the load-bearing tissues of the buttocks.
Wound Measurement Device
The Wound Measurement Device (WMD) is a low-cost and high-precision wound measurement device that offers an option to current low- and high-tech devices. A prototyping platform based upon a commercial cell phone, AT&T Tilt PDA, has been clinically tested. The system uses off-the-shelf electronics and is programmed in C#.
