Background: Maintenance of physical activity is of paramount importance in geriatric care and it is imperative to be able to objectively assess physical activity level in the geriatric population. However, majority of the established assessment protocols are designed for relatively younger adults, and are not validated for the elderly. The Senior Fitness Test (SFT) is aimed at assessing the underlying functional fitness for older adults. Methods: A community based prospective study to assess the test-retest reliability of SFT in elderly subjects, aged 65 -75 years. Subjects with any acute illnesses, acute musculoskeletal injury, hypertension, and with visual problems hampering test performance were excluded. The study was conducted by two observers on two days at the subject's own locality. The Intraclass Correlation Coefficient (ICC) with 95% confidence intervals (CIs) was used as a measure of relative reliability. The standard error of measurement and minimal detectable change (MDC) were used to measure absolute reliability. Results: Thirty one participants (mean age-68.32±2.58 years) were assessed. The ICC reflected high reliability (0.934-0.994) in all SFT items. MDC values (90% CI) for various SFT were as follows: chair sit and reach test = 1.55, back scratch test = 1.41, 30 second chair stand test = 1.15, 30-second arm curl test = 2.53, 8 foot up-and-go test = 1.47 and 2-minute step test = 1.40. Bland-Altman plots for all the tests were positively skewed and heteroscedastic.
Conclusion:The SFT showed high test-retest reliability and thus is suitable for evaluating physical fitness in elderly and can be utilized in larger studies for the geriatric population.
Since the publication of the Institute of medicine report, To Err Is Human: Building a safer health system, notes that errors in health care are a significant cause of death and injury and the emphasis on patient safety has steadily increased. The rehabilitation professionals engaged for the management of patient with locomotor disabilities should incorporate elements of patient safety into their practices and also to stimulate research associated with prevalence of analysis of error/harm which occurs during the rehabilitation phase and also to develop and validate certain specific measuring tools and instruments for patient safety issues.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
