Excessive reliance on wheelchairs in individuals with tetraplegia or paraplegia due to spinal cord injury (SCI) leads to many medical co-morbidities, such as cardiovascular disease, metabolic derangements, osteoporosis, and pressure ulcers. Treatment of these conditions contributes to the majority of SCI health care costs. Restoring able-body-like(More)
Spinal cord injury (SCI) is a devastating medical condition affecting 1.2 million people in the United States. Central neuropathic pain is one of the most common medical complications of SCI. Current treatment options include opioids, antiepileptic agents such as gabapentin, antispastic agents such as baclofen or tizanidine, and tricyclic acid. Other(More)
BACKGROUND Persons with spinal cord injury (SCI) are at high risk for pressure ulcers (PrUs) throughout their lifetime due to decreased mobility, lack of sensation, and other physiological changes. The high prevalence and recurrence rates, and costs associated with PrUs in veterans with SCI indicate the need for a reliable and practical method of detecting(More)
This paper reports the clinical experiences and preliminary observations from implanted microstimulators used to reduce some impairments following a stroke. Ongoing research protocols to reduce shoulder subluxation and hand contractures using BION stimulation are described. Comparison of compliance and patient satisfaction between individuals exercising at(More)
An able-bodied subject used walking motor imagery to accurately operate a non-invasive brain-computer interface (BCI) controlled robotic gait orthosis. This finding represents the first successful demonstration of a BCI-controlled lower extremity prosthesis for independent ambulation, with significant implications for restoring ambulation to individuals(More)
The objectives of this article are to (1) provide an overview of existing spinal cord injury (SCI) clinical research databases-their purposes, characteristics, and accessibility to users; and (2) present a vision for future collaborations required for cross-cutting research in SCI. This vision highlights the need for validated and relevant data for(More)
Implementation into real-world practice of interventions previously studied in randomized controlled trials is an ongoing challenge. In this article, we describe the methodology we used for the first phase of a project for the implementation and outcomes assessment of an occupational therapy pressure ulcer prevention intervention for people with spinal cord(More)
