Comparison of Nonmicroprocessor Knee Mechanism versus C-Leg on Prosthesis Evaluation Questionnaire, Stumbles, Falls, Walking Tests, Stair Descent, and Knee Preference
INTRODUCTION Amputees seek prostheses that meet their functional needs to the fullest extent possible. For transfemoral (TF) amputees, a prosthetic knee mechanism is required. However, the number and type of available prosthetic knees from which...
Curb Descent Testing of Suspension Manual Wheelchairs
Much research has been done on whole-body vibrations (WBV) and their potentially damaging effects on the human body, and though no definitive relationship exists, the development of low back pain and secondary injuries in persons exposed to WBV...
Department of Veterans Affairs-Medicare Dual Beneficiaries with Stroke: Where Do They Get Care?
INTRODUCTION Stroke is a key public health issue and a leading cause of disability [1]. Each year, an estimated 500,000 individuals experience a first stroke and an additional 200,000 individuals experience a recurrent stroke [2]. Stroke is far...
Dynamic Monitoring of Forearm Muscles Using One-Dimensional Sonomyography System
INTRODUCTION Electromyography (EMG), an electrical signal collected by electrodes during muscle contractions, represents the bioelectrical properties of skeletal muscles and demonstrates the physiological processes of muscle contraction. It has...
Effect of Anodal and Cathodal Microamperage Direct Current Electrical Stimulation on Injury Potential and Wound Size in Guinea Pigs
INTRODUCTION Skin wounds can be a major medical, social, and economic problem for patients [1]. Chronic ulcers (pressure sores, diabetic ulcers, venous stasis ulcers, nonhealing ulcers, etc.) are especially troublesome problems, with complex...
Effects of Backrest Positioning and Gear Ratio on Nondisabled Subjects' Handcycling Sprinting Performance and Kinematics
INTRODUCTION Over the last 20 years, researchers have shown new interest in a complementary mode of propulsion for wheelchair-dependent users: "handbiking" or "handcycling," which is now widely used in rehabilitation and sporting programs for...
From Editor's Desk/thank You to JRRD Reviewers
The Journal of Rehabilitation Research and Development (JRRD) has accomplished much in the past year, but we must start by thanking the 439 reviewers who volunteered their time and knowledge to review each article submission. The JRRD Web site...
How Many People Would Benefit from a Smart Wheelchair?
INTRODUCTION Several studies have shown that both children and adults benefit substantially from access to independent mobility [1-3]. Independent mobility increases vocational and educational opportunities, reduces dependence on caregivers and...
Integrated Electromyogram and Eye-Gaze Tracking Cursor Control System for Computer Users with Motor Disabilities
INTRODUCTION Typically, nondisabled individuals communicate with a computer using standard input devices such as a mouse, trackball, touch pad, or keyboard. An estimated 250,000 to 400,000 individuals in the United States and more than 2 million...
Investigation of Large Transit Vehicle Accidents and Establishing Appropriate Protection for Wheelchair Riders
INTRODUCTION Wheelchairs users who ride buses should be afforded a level of safety comparable to that enjoyed by other passengers [1]. National and international efforts to improve wheelchair rider safety have produced safety standards for the...
Pilot Safety and Feasibility Study of Treadmill Aerobic Exercise in Parkinson Disease with Gait Impairment
INTRODUCTION Despite effective symptomatic therapies for Parkinson disease (PD), function declines as patients develop motor fluctuations, gait impairment, and postural instability. Gait abnormalities may persist even when patients are adequately...
Potential of Olfactory Ensheathing Cells for Cell-Based Therapy in Spinal Cord Injury
INTRODUCTION More than 11,000 traumatic spinal cord injuries (SCIs) are estimated to occur in the United States each year [1]. Unfortunately, aside from good medical management, no generally accepted interventional therapies are available. While...
Project LIFE - Learning to Improve Fitness and Function in Elders: Methods, Design, and Baseline Characteristics of Randomized Trial
INTRODUCTION Most older adults are not regularly physically active [1]. Physical inactivity is associated with increased rates of morbidity, functional limitations, disability, and mortality. Concurrent with this finding are the continued reports...
Rehabilitation Implications of Stepper Exercise Technique on Exertion and Hip Extensor Muscle Activation - a Small Exploratory Study
INTRODUCTION Maintenance of erect posture is a coupled action that involves the back and hip extensor muscles [1-2]. The gluteus maximus is particularly important because it is a crucial link in the transfer of forces from the legs to the back...
Review of Secondary Physical Conditions Associated with Lower-Limb Amputation and Long-Term Prosthesis Use
INTRODUCTION Amputations during service in the U.S. Armed Forces are a concern not only for service members who have lost limbs during recent military engagements but also for those who experienced limb loss during prior combat and peacetime...
Silver Hydrogel Urinary Catheters: Evaluation of Safety and Efficacy in Single Patient with Chronic Spinal Cord Injury
INTRODUCTION Urinary tract infections (UTIs) place a large health burden on patients with spinal cord injury (SCI) who have neurogenic bladder dysfunction, especially those patients who use indwelling catheters. Nationally and as reported by...
Synchronous Stimulation and Monitoring of Soleus H Reflex during Robotic Body Weight-Supported Ambulation in Subjects with Spinal Cord Injury
INTRODUCTION The soleus H reflex has been used as a tool for assessing monosynaptic reflex excitability in humans during both rest and voluntary activity [1]. The amplitude of the soleus H reflex is modulated in a task-dependent manner, such...
Using Veterans' Perspectives to Enhance Rehabilitation Outcome Measures: Value of Qualitative Methods
Innovative rehabilitation interventions and technologies aimed at recovery of walking show great promise and are receiving considerable support from the Department of Veterans Affairs (VA) Rehabilitation Research and Development (RR&D) Service....
