Modified 30-second Sit to Stand test predicts falls in a cohort of institutionalized older veterans.

ABSTRACT: Physical function performance tests, including sit to stand tests and Timed Up and Go, assess the functional capacity of older adults. Their ability to predict falls warrants further investigation. The objective was to determine if a modified 30-second Sit to Stand test that allowed upper extremity use and Timed Up and Go test predicted falls in institutionalized Veterans. Fifty-three older adult Veterans (mean age = 91 years, 49 men) residing in a long-term care hospital completed modified 30-second Sit to Stand and Timed Up and Go tests. The number of falls over one year was collected. The ability of modified 30-second Sit to Stand or Timed Up and Go to predict if participants had fallen was examined using logistic regression. The ability of these tests to predict the number of falls was examined using negative binomial regression. Both analyses controlled for age, history of falls, cognition, and comorbidities. The modified 30-second Sit to Stand was significantly (p < 0.05) related to if participants fell (odds ratio = 0.75, 95% confidence interval = 0.58, 0.97) and the number of falls (incidence rate ratio = 0.82, 95% confidence interval = 0.68, 0.98); decreased repetitions were associated with increased number of falls. Timed Up and Go was not significantly (p > 0.05) related to if participants fell (odds ratio = 1.03, 95% confidence interval = 0.96, 1.10) or the number of falls (incidence rate ratio = 1.01, 95% confidence interval = 0.98, 1.05). The modified 30-second Sit to Stand that allowed upper extremity use offers an alternative method to screen for fall risk in older adults in long-term care.

Project description:BackgroundIn patients with COPD, the 6-minute walk test (6MWT) and the 30-second sit-to-stand test (30sec-STS) are widely used as clinical outcome measures of walking capacity, lower limb muscle strength, and functional ability. Due to a documented learning effect, at least two trials are recommended for assessment. The aim of our study was to investigate the intra- and inter-rater reliability and agreement of the two tests in patients with severe and very severe COPD (FEV1 <50%).Patients and methodsFifty patients (22 females; mean [SD]: age 67 [9] years, FEV1 predicted 32 [9]%) were assessed with the 6MWT and the 30sec-STS twice by the same assessor on test-day 1 (T1) and by another assessor 7-10 days later on test-day 2 (T2).ResultsThe 6MWT intra- and inter-rater reliability (intraclass correlation coefficient, ICC1.1) was 0.98 (lower limit 95% CI: 0.94) and 0.96 (lower limit 95% CI: 0.94), respectively, and agreement (standard error of the measurement, SEM) was 14.8 and 20.5 m, respectively. The 30sec-STS intra- and inter-rater reliability and agreement results were, respectively, ICC1.1 0.94 (lower limit 95% CI: 0.90) and 0.92 (lower limit 95% CI: 0.86), with SEM of 0.97 and 1.14 repetitions. There was no difference (95% CI: -5.3; 8.1) between the 6MWT distances on T1, while the mean walking distance improved 7.9 m (0.0 m; 15.8 m) from T1 to T2. Improvement on the same test date was less likely (OR: 3.6 [95% CI: 1.1; 11.8], Fisher's exact test, P=0.047) in patients who walked less than 350 m in the 6MWT. We found no clinically relevant learning effect in the 30sec-STS.ConclusionIn patients with severe and very severe COPD the 6MWT and the 30sec-STS showed excellent intra- and inter-rater reliability and acceptable agreement. No learning effect was documented for the tests when performed on the same day. Our data suggest that in clinical practice using different assessors is acceptable, and that a single test trial may be sufficient to assess patients with severe and very severe COPD.

Project description:The sit-to-stand test is commonly used by clinicians and researchers to analyze the functional capacity of older adults. The test consists to stand up and sit down from a chair and can be applied either in function of a predetermined number of repetitions to be completed or according to a specific time. The most common tool used by the evaluators is the chronometer, due to its low cost and ease of use. However, this tool may miss some important data throughout the test, such as the stand-up time and the total time of each repetition, as well as other kinematic and kinetic variables. Therefore, it is necessary to develop new cheap and affordable tools to capture these data with reliability. In this perspective, the development of mobile applications can be a valid and reliable alternative for the automatic calculation of different variables with sensors' data, including acceleration, velocity, force, power, and others. Thus, in this paper, we present a dataset related to the acquisition of the accelerometer data from a commodity smartphone for the measurement of different variables during the sit-to-stand test with institutionalized older adults. Forty participants (20 men and 20 women, 78.9 ± 8.6 years old, 71.7 ± 15.0 kg, 1.57 ± 0.1 m) from five community-dwelling centers (Centro de Dia e Apoio Domiciliário de Alcongosta, Lar Nossa Senhora de Fátima, Centro Comunitário das Minas da Panasqueira, Lar da Misericórdia, and Lar da Aldeia de Joanes) from Fundão, in Portugal, volunteered to participate in the data acquisition. A mobile phone was attached to the waist of the participants to capture the data during the sit-to-stand test. Then, seated in an armless chair with the arms crossed over the chest, the participants stood up and sat down in a chair six times. The stand-up action was ordered by an acoustic signal emitted by the mobile application. All data were acquired with the mobile application, and the outcome measures were the reaction time, total time, stand-up time and movement time. This paper describes the procedures to acquire the data. These data can be reused for testing machine learning or other methods for the evaluation of neuromuscular function in older adults during the sit-to-stand test.

Project description:Fatigue, dyspnea and pain are the main limitations of patients with long COVID. The aim of this study was to determine the feasibility of the 30 s sit-to-stand (30s-STS) test in the telehealth setting and its relationship to persistent symptoms in a sample of non-hospitalized patients with long COVID. A cross-sectional study was conducted in community patients with long COVID. Data collection and assessments were performed by videoconference and consisted of the fatigue assessment scale (FAS), London activity of daily living scale (LCADL), post-COVID-19 functional status (PCFS) and European quality of life questionnaire (EQ-5D-5L), including the pain/discomfort dimension. The 30s-STS test was performed using a standardized protocol adapted for remote use, and the modified Borg scale (0−10) was used to assess dyspnea and lower limb fatigue immediately after the test. The feasibility of the 30s-STS test was assessed by the proportion of eligible participants who were able to complete the test. Safety was assessed by the number of adverse events that occurred during the test. Seventy-nine participants were included (median age: 44 years, 86.1% women). Performance in the 30s-STS test was 11.5 ± 3.2 repetitions with 60.8% of the sample below reference values. All eligible participants were able to complete the test. No adverse events were reported during the evaluation. Participants with lower 30s-STS performance had more fatigue and dyspnea, worse quality of life, more severe pain/discomfort, and worse functional status (p < 0.05). A significant correlation was obtained between LCADL and dyspnea, reported on the Borg scale (0−10) post 30s-STS (r = 0.71; p < 0.001). In conclusion, the 30s-STS test proved to be a feasible test to implement in the telehealth setting and is related to fatigue, dyspnea, quality of life and pain in non-hospitalized patients with long COVID. Clinicians may use this test when assessment of the physical sequelae of COVID-19 in the face-to-face setting is not possible.
