(543 women and 508 men) were recruited from community-dwelling people in Shiraz, Iran, through announcements posted in well-transited locations in all 11 municipal districts of the city. Participants were excluded if they had any history of surgery of the spine or lower extremities, any balance

The Fall Prevention Center of Excellence designed three progressive-intensity fall prevention program models, Increasing Stability Through Evaluation and Practice (InSTEP), to reduce risk in community-dwelling older adults. Each model included physical activity, medical risk, and home safety components and was implemented as a 12-week program for small class sizes (12–15 people) in community and senior centers. Change in fall rates and fall risk factors was assessed using a battery of performance tests, self-reports of function, and fall diaries in a 3-group within-subjects (N = 200) design measured at baseline, immediately postintervention, and at 3 and 9 months postintervention. Overall, participants experienced a reduction in falls, improved self-perception of gait and balance, and improved dynamic gait function. The medium-intensity InSTEP model signifcantly (p = .003) reduced self-reported falls in comparison with the other models. InSTEP is a feasible model for addressing fall risk reduction in community-dwelling older adults.

The use of low-cost interactive game technology for balance rehabilitation has become more popular recently, with generally good outcomes. Very little research has been undertaken to determine whether this technology is appropriate for balance assessment. The Wii balance board has good reliability and is comparable to a research-grade force plate; however, recent studies examining the relationship between Wii Fit games and measures of balance and mobility demonstrate conflicting findings. This study found that the Wii Fit was feasible for community-dwelling older women to safely use the balance board and quickly learn the Wii Fit games. The Ski Slalom game scores were strongly correlated with several balance and mobility measures, whereas Table Tilt game scores were not. Based on these findings, the Ski Slalom game may have utility in the evaluation of balance problems in community-dwelling older adults.

This cross-sectional study investigated associations between reasons to go outdoors and objectively-measured walking activity in various life-space areas among older people. During the study, 174 community-dwelling older people aged 75–90 from central Finland wore an accelerometer over seven days and recorded their reasons to go outdoors in an activity diary. The most common reasons for going outdoors were shopping, walking for exercise, social visits, and running errands. Activities done in multiple life-space areas contributed more to daily step counts than those done in the neighborhood or town and beyond. Those who went shopping or walked for exercise accumulated higher daily step counts than those who did not go outdoors for these reasons. These results show that shopping and walking for exercise are common reasons to go outdoors for community-dwelling older people and may facilitate walking activity in older age. Future studies on how individual trips contribute to the accumulation of steps are warranted.

The purpose of this prospective cohort study was to determine whether the maximal width of the base of support (BSW) measure is able to predict the risk of multiple falls in community-dwelling women. Thirty-eight community-dwelling women (mean age of 72 ± 8 years old) participated. Falls were prospectively recorded during the following year. Overall, 29 falls were recorded; six (16%) women were multiple fallers and 32 (84%) were nonfallers. There was a significant difference in the BSW between the fallers and nonfallers (F[1, 37] = 5.134 [p = .030]). A logistic regression analysis indicated a significant contribution of the BSW test to the model (odds ratio = 0.637; 95% CI [0.407, 0.993]; p = .046 per 1 cm).The cut-off score was determined to be 27.8 cm (67% sensitivity and 84% specifcity). These results indicate that women with a smaller BSW at baseline had a significantly higher risk of sustaining a fall.

As a preliminary step in developing the physical-functioning measure of the Late-Life Function and Disability Instrument (LLFDI), the authors compared its items with the physical-functioning items (PF-10) on the SF-36 Health Survey. They compared the item coverage, hierarchy, and scale-separation properties of the PF-10 items with those of the physical-functioning items of the LLFDI. Both questionnaires were administered to 50 community-dwelling older adults. A partial-credit, 1-parameter, item-response-theory model was used to scale the items. The LLFDI improved the range of ability of daily activities that was encompassed by the PF-10 items by 46%. By sequentially deleting new items with poor fit to the overall scale and items with redundant content, the authors developed a scale more capable of accurately assessing low-functioning activities. The LLFDI function component incorporates a broader content range and better person and item separation than the PF-10 items. It appears to have potential as a comprehensive functional-activity assessment for community-dwelling older adults.

Background:

Despite benefits of physical activity (PA), exercise is also associated with risks. Musculoskeletal injury (MSI) risk increases with exercise frequency/intensity. MSI is associated with costs including medical care and time lost from work.

Purpose:

To evaluate the economic costs associated with PA-related MSIs in community-dwelling women.

Method:

Participants included 909 women in the Women’s Injury Study reporting PA behaviors and MSI incidence weekly via the Internet for up to 3 years (mean follow-up 1.89 years). Participants provided consent to obtain health records. Costs were estimated by medical records and self-reports of medical care. Components included physician visits, medical facility contacts, medication costs, and missed work.

Results:

Of 909 participants, 243 reported 323 episodes of expenditure or contact with the health care system associated with PA. Total costs of episodes ranged from $0–$18,934. Modal cost was $0 (mean = $433 ± $1670). Costs were positively skewed with nearly all participants reporting no or very low costs.

Conclusions:

About 1 in 4 community-dwelling women who are physically active experienced a PA-related MSI. The majority of injuries were minor, and large expenses associated with MSI were rare. The long-term health benefits and costs savings resulting from PA likely outweigh the minor costs associated with MSI from a physically-active lifestyle.
