ICARE:An Intelligently Controlled Assistive Rehabilitation Elliptical Training System to Promote Walking and Fitness in Persons with Physical Limitations and Chronic Conditions

Funding Agency: The National Institute on Disability and Rehabilitation Research (NIDRR Award No. H133G070209 - Principal Investigator: J.M. Burnfield, Ph.D., P.T.)

Project Description: Regaining walking ability and physical fitness are central goals for many individuals participating in rehabilitation programs, and this desire continues beyond discharge. Yet many face barriers to accessing optimal treatment programs in healthcare settings and community based fitness facilities. Barriers include lack of affordable and accessible equipment, and sufficient staff with appropriate expertise. This project developed ICARE, an Intelligently Controlled Assistive Rehabilitation Elliptical trainer and therapeutic program, to help physically challenged individuals and those with chronic conditions regain and/or retain their walking ability and physical fitness. To date, over 140 individuals with and without disabilities have participated in extensive biomechanical and equipment evaluations during the initial development period as well as subsequent clinical testing in physical rehabilitation environments and a fitness center. The ICARE design promotes greater elliptical trainer accessibility so that people with disabilities can engage in effective therapeutic exercise and gait programs in order to promote optimal health, quality of life, and maximum independence.

Current Research



First Hope Initiative

Funding Agency: Department of Health and Human Services, Health Resources and Services Administration (Federal Award No 1 R1CRH20680-01-00 - Principal Investigator: J.M. Burnfield, Ph.D., P.T.)

Project Description: This technology and research initiative will increase the functional independence, quality of life, and outcomes of patients with severe disabilities arising from such conditions as stroke, brain injury and spinal cord injury. The focus of this work is to develop affordable technology packages that maximize an individual’s ability to control their environment (lights, windows, bed, etc.), communicate their needs, and engage in therapeutically meaningful activities at bedside 24 hours a day, 7 days a week from the first day of inpatient rehabilitation. The ultimate goal is to seamlessly integrate technology across the rehabilitation environment to break down barriers in communication, environmental control and independence frequently experienced by adults and children with severe physical disabilities arising from spinal cord injuries, strokes or traumatic brain injuries. The technology will enable patients to have more independence and control from their very first days in rehabilitation, helping the individuals and their families to focus more fully on rehabilitation and maximizing progress during this critical recovery period.



Safe Patient Handling: An Evaluation of Sit-to-stand Transfers

Funding Agency: Supported, in part, by the Undergraduate Creative Activities and
Research Experiences Program, Agricultural Research Division grants from the University of Nebraska-Lincoln, and the Donald and Pearl Winkler for Stroke Research Institute Endowment.

Project Description: Workplace injuries arising from improper handling of patients during transfers are a prevalent problem in the healthcare field and are concerning due to the risk of injury to both clinicians and patients. One tool that has emerged from the emphasis on safe patient handling is the sit-to-stand transfer device. A sit-to-stand transfer device is a battery powered machine that transfers a patient from a seated to a standing position, moves the individual from one place to another, and returns them to a seated position (e.g. moving from sitting on the bed to a wheelchair). As many individuals recovering from a stroke find it difficult to perform a sit-to-stand transfer, regaining this functional ability often becomes a central goal within rehabilitation programs. The aims of this research are to explore both the clinician’s and patient’s joint movements and muscle activation during device-assisted and clinician-assisted transfers.

Association between musculoskeletal injuries and the usage of patient-handling devices among rehabilitation physical therapists

Funding Agency: Heartland Center for Occupational Health and Safety Pilot Grant, University of Iowa (Principal Investigator: B. McCrory, Ph.D.; Sponsor: J.M. Burnfield, Ph.D., P.T.; Co-investigators: J.L. Meza, Ph.D.; A.R. Darragh, Ph.D., OTR/L)

Project Description: This is a cross-sectional survey of physical therapists and physical therapy assistants currently practicing at rehabilitation centers in Iowa, Kansas, Missouri and Nebraska. The aims of this study are to determine the prevalence and severity of work-related musculoskeletal disorders (WMSDs), and the associations between WMSDs and specific exposure risk factors such as usage of patient-handling equipment.
