The incidence of falls, fall-related injuries, and fall-associated costs continue to rise along with the increase in the aging population. Community-based fall prevention programs for the elderly are proliferating in an attempt to address this health problem. ⋯ This article presents a review of randomized controlled trials that investigated the effectiveness of fall prevention programs for community-dwelling older adults. Following a comprehensive critical analysis of the literature, we present the following guidelines: (1) multifactorial fall prevention programs appear to be more effective for older individuals with a previous fall history versus a nonselect group; (2) medication and vision assessment with appropriate health practitioner referral should be included in a falls screening examination; (3) exercise alone is effective in reducing falls and should include a comprehensive program combining muscle strengthening, balance, and/or endurance training for a minimum of 12 weeks; and (4) home hazard assessment with modifications may be beneficial in reducing falls, especially in a targeted group of individuals.

The Department of Veterans Affairs Veterans Health Administration cares for approximately 15% of persons with spinal cord injury (SCI) in the United States. However, the nature and characteristics of pain among veterans with SCI are not well understood. This study used a postal survey to compare veterans with SCI and nonveterans with SCI on pain intensity; pain interference; functioning; and other pain, demographic, and medical characteristics. ⋯ However, differences in functioning between veterans and nonveterans were attributable to age differences between the groups. In summary, differences between veterans with SCI and nonveterans with SCI were few and small in magnitude, suggesting that veterans with SCI are not at greater risk for pain and pain-related problems. However, pain-related catastrophizing may be a particular concern among veterans with SCI.

We analyzed healthcare costs and medical conditions for 2,008 veterans with spinal cord injuries and disorders (SCI/Ds) near end of life. The average age at SCI/D onset and/ or occurrence was 42 years and at death was 66 years. ⋯ The average cost was $24,900 in the second year before end of life and reached $61,900 in the final year. Before end of life, costs accelerated during the final year from $3,100 in month 12 to $14,600 in the final month.

Patients with Parkinson disease (PD) may have decreased physical activity due to motor deficits. We recently validated the reliability of step activity monitors (SAMs) to accurately count steps in PD, and we wished to use them to evaluate the impact of disease severity on home activity levels in PD. Twenty-six subjects with PD (Hoehn and Yahr disease stage 2-4) were recruited to participate in a study of activity levels over 48 hours. ⋯ A microprocessor-linked SAM accurately counted steps in subjects with PD. The number of steps taken correlated highly with disease severity. SAMs may be useful outcome measures in PD.

Computer-controlled electrical stimulation (ES)-induced leg cycle ergometer (ES-LCE) exercise can be beneficial for individuals with spinal cord injury (SCI), but exercise performance is often insufficient for eliciting continuous gains in cardiopulmonary training adaptations. The first purpose of this study was to determine whether a modified ES-LCE improved exercise performance and responses compared with the standard ES-LCE. Modifications to the ES-LCE included increased ES current amplitude (140-300 mA), added shank muscle activation, and increased ES firing angle ranges (+55 degrees). ⋯ No significantly different peak values for power output and stroke volume were found for the two systems, but the modified ES-LCE elicited significantly higher peak values for oxygen uptake (+22%), carbon dioxide production (+51%), pulmonary ventilation (+37%), cardiac output (+32%), heart rate (+19%), and blood lactate concentration (+50%). Power output, metabolic rate, and lower-limb muscle strength increased significantly following training. This study showed that an ITP with the modified ES-LCE can elicit marked improvements in ES-LCE performance (peak power output), peak metabolic and cardiorespiratory responses, and muscle strength in men with SCI, even in those subjects whose performance has plateaued during training on the standard ES-LCE.
