Book excerpt: Abstract: PURPOSE: The purpose of this study was to investigate the effect of an aquatic exercise program on balance among community-dwelling older adults. SUBJECTS: Twenty-one subjects over the age of 65 who were residents of the Loomis Village Retirement Communities in South Hadley, Massachusetts. Exclusion criteria included: medical conditions that affect physical activity, had physical therapy, were seeing a chiropractor, or currently had any other kinds of therapy such as acupuncture, massage, or occupational therapy. Inclusion criteria for subject selection required that each subject be 65 years or older, an independent ambulator with or without an assistive device, independent in all activities of daily living, and able to respond to verbal cues. All subjects signed informed consent forms and received written medical clearance from their primary care physicians. METHODS: Study was a mixed factor model with the treatment condition as a between-subject factor, and test session as a within-subject factor. Twelve subjects volunteered to participate in the aquatic gr6up (age M=8l.58years, SD 4.58). Nine subjects volunteered to participate in the control group (age M=82.44 years, SD 4.93). All participants were pre-tested using the Timed Up and Go Test (TUG), Functional Reach Test (FRT), and Survey of Activities and Fear of Falling in the Elderly (SAFE). Aquatic group subjects participated in a 6-week program of aquatic exercise. Members of the control group were instructed not to change their daily routine. All participants were then re-tested using the TUG, FRT, and SAFE at week 7. ANALYSES: SPSS 12.0 was used to analyze data. Descriptive statistics and frequencies were obtained to provide a profile of the sample characteristics. Data were analyzed with independent and paired t-tests. Change scores were calculated relative to baseline measures. RESULTS: There was no significant difference between the group sat pre-test in all dependent variables (p>.01). There was also no significant difference in the change of any of the dependent variables between the groups at post-test (p>.01). The TUG and FRT scores had a moderate negative correlation at both pre-test and posttest. Results of a post-hoc power analysis yielded a power of .8%. CONCLUSIONAND RELEVANCE: Results did not support those obtained by previous researchers, who found that aquatic exercise had a positive effect on balance. The limited power of the study suggests that a significant difference may have existed between the groups at post-test, but was not detectable with the sample size of this study. Limitations of the study included: limited sample size, nonrandomized groups, lack of reliability of SAFE scores, participant confusion during SAFE administration, highly active exercise group, and short study period. Despite the lack of a statistically significant difference between groups, an improvement in both TUG and FRT scores was observed in the aquatic exercise group. Suggestions for future studies include: larger sample size with randomized groups; longer time period of exercise intervention; outcome measures appropriate to population; and research needed to develop more appropriate fear of falling assessment tools.
