Feasibility of implementing the Strong for Life program in community settings.

PURPOSE: We describe the results of the dissemination of an efficacious, home-based exercise program called Strong for Life as it was implemented in a nationwide, volunteer caregiving program called Faith in Action, including training of volunteers who implemented the program, recruitment of older adult participants, exercise adherence, and attitudes and perceptions of program staff and participants. DESIGN AND METHODS: Frail, homebound older adults (N = 105) were recruited from 10 Faith in Action sites to participate in the Strong for Life exercise program. Volunteer trainers (n = 103) were trained by physical therapists to assist the older adults with the program. Surveys were conducted with older adults, volunteer trainers, and Faith in Action sites at baseline and after the older adults had been engaged in the program for 4 months. RESULTS: Satisfaction with program components was very high: At follow-up, 100% of volunteers and 98.6% of older adults rated the program positively. Participants reported engaging in exercise on average 2.2 times per week, with 53% of the participants exercising at least 2 to 4 times per week. Participants also had significant improvements in the Short Form-20 social functioning scale. There were no serious adverse events reported. IMPLICATIONS: Dissemination of the Strong for Life program in a community setting using trained lay volunteers was feasible, acceptable, and safe. Existing volunteer caregiving organizations such as Faith in Action offer a feasible and safe means of disseminating late-life exercise programs to the frail older population.

Randomized controlled trial of physical activity counseling for older primary care patients.

BACKGROUND: Regular physical activity reduces the risk for chronic diseases among older adults. Older adults are likely to be seen by primary care clinicians who can play a role in promoting physical activity among their patients. DESIGN: In this randomized controlled trial (1998-2003; data analyzed 2004-2005), we compared the effects of brief advice to exercise from a clinician supplemented by telephone-based counseling by health educators (extended advice) to brief advice from a clinician alone (brief advice). SETTING/PARTICIPANTS: A total of 100 primary care patients (63.2% female, 14.7% minority, mean age=68.5 years) participated in the trial. INTERVENTIONS: The extended-advice intervention consisted of clinician advice plus exercise counseling via telephone provided by research staff, and the brief advice condition consisted of clinician advice alone. Both interventions focused on promoting moderate-intensity physical activity. MAIN OUTCOME MEASURES: Self-reported physical activity using the 7-Day Physical Activity Recall instrument and objective activity monitoring using Biotrainers were assessed at baseline, and at 3 and 6 months. RESULTS: Participants in the extended-advice arm reported significantly greater participation in moderate-intensity physical activity than the brief-advice group at 3 months (+57.69 minutes vs 12.45 minutes; 3.84 kcal/week vs 0.83 kcal/week) and 6 months (+62.84 minutes vs 16.60 minutes; 4.19 kcal/week vs 1.1 kcal/week). Objective activity monitoring also showed significantly increased physical activity among extended-advice versus brief-advice participants at both time points (+50.79 vs -11.11; +42.39 vs -24.18, respectively). CONCLUSIONS: These data indicate that clinician advice with follow-up counseling can promote adoption of moderate-intensity physical activity among older, primary care patients.

Development of the home and community environment (HACE) instrument.

OBJECTIVE: To develop and pilot test the Home and Community Environment instrument (HACE), a self-report measure designed to characterize factors in a person's home and community environment that may influence level of participation. DESIGN: A cross-sectional survey. SUBJECTS: Sixty-two adults recruited from community organizations and an outpatient rehabilitation center. METHODS: Six environmental domains were assessed: (i) home mobility; (ii) community mobility; (iii) basic mobility devices; (iv) communication devices; (v) transportation factors; and (vi) attitudes. Descriptive statistics, Kappa statistics and Kruskal-Wallis tests were used to ascertain whether persons were capable of assessing characteristics of their environment, could do so reliably and whether the distribution of environmental factors differed by type of living situation. RESULTS: Participants were capable of characterizing their home environment and most aspects of their community with acceptable reliability. The median percent agreement of the 6 environmental domains ranged from 75% to 100% (median Kappa values ranged from 0.47 to 1.0). Percent agreement for individual HACE items ranged from 58% to 100%. The lowest reliability values were observed in the community mobility domain. As hypothesized, individuals who lived in private homes characterized home and community mobility factors differently from those who lived in multi-unit complexes; evidence of HACE's validity. CONCLUSION: HACE is a promising self-report instrument for assessing characteristics of an individual's home and community environments. Additional research is needed to assess its utility for rehabilitation research.

Function and disability in late life: comparison of the Late-Life Function and Disability Instrument to the Short-Form-36 and the London Handicap Scale.

PURPOSE: We evaluated the Late-Life Function and Disability Instrument's (LLFDI) concurrent validity, comprehensiveness and precision by comparing it with the Short-Form-36 physical functioning (PF-10) and the London Handicap Scale (LHS). METHODS: We administered the LLFDI, PF-10 and LHS to 75 community-dwelling adults (> 60 years of age). We used Pearson correlation coefficients to examine concurrent validity and Rasch analysis to compare the item hierarchies, content ranges and precision of the PF-10 and LLFDI function domains, and the LHS and the LLFDI disability domains. RESULTS: LLFDI Function (lower extremity scales) and PF-10 scores were highly correlated (r = 0.74 - 0.86, p > 0.001); moderate correlations were found between the LHS and the LLFDI Disability limitation (r = 0.66, p < 0.0001) and Disability frequency (r = 0.47, p < 0.001) scores. The LLFDI had a wider range of content coverage, less ceiling effects and better relative precision across the spectrum of function and disability than the PF-10 and the LHS. The LHS had slightly more content range and precision in the lower end of the disability scale than the LLFDI. CONCLUSIONS: The LLFDI is a more comprehensive and precise instrument compared to the PF-10 and LHS for assessing function and disability in community-dwelling older adults.

Changes in function and disability after resistance training: does velocity matter?: a pilot study.

OBJECTIVE: To compare the effects of high- and low-velocity resistance training on functional performance and disability outcomes in physically limited older women. DESIGN: A total of 16 wk of high-velocity resistance training or traditional low-velocity resistance training consisting of knee extension and leg press exercises was performed three times per week by 30 women with self-reported disability to compare their effect on functional performance and disability. Tests of dynamic balance, stair-climb time, chair-rise time, and gait velocity were used to assess changes in functional performance. Changes in disability were assessed using the Medical Outcomes Study Short Form. RESULTS: Dynamic balance and stair-climb time improved 8% and 10%, respectively, with training. Self-reported disability, physical functioning, role physical, and mental health improved 11, 9, and 5% with training, respectively. There were no significant differences between high- and low-velocity training groups. CONCLUSIONS: High- and low-velocity training achieved similar improvements in functional performance and disability. Improvements in functional performance and disability were modest compared with robust increases in strength and power. Specific modes of training or behavioral strategies may be necessary to optimize improvements in these outcomes.
