Project description:BackgroundDuration of therapy time is an inadequate indicator of stroke rehabilitation. Steps, duration, and intensity of active therapy time may provide a better indicator of practice.ObjectiveThis study quantified usual walking practice in terms of steps, duration and intensity of active therapy time, and distance walked during physical therapy sessions in people with sub-acute stroke undertaking inpatient rehabilitation and to examine whether usual walking practice differed depending on walking ability.MethodsA prospective observational study was conducted across two metropolitan rehabilitation units in Australia. Twenty-four stroke survivors were observed over three physical therapy sessions. Walking ability was categorized as unassisted or assisted based on Item 5 of the Motor Assessment Scale. Walking practice was categorized as basic or advanced. Steps, duration, intensity and distance walked were measured during physical therapy sessions.ResultsOverall, participants took 560 steps (SD 309) over 13min (SD 6) at an intensity of steps 44 steps/min (SD 17) and walked 222m (SD 143) in physical therapy. Unassisted walkers (n=6, 25%) undertook more (or trended towards more) practice of advanced walking than assisted walkers in terms of steps (MD 254 steps, 95% CI 48-462), duration (MD 5min, 95% CI 0-10), intensity (MD 18steps/min, 95% CI -8 to 44) and distance (MD 112m, 95% CI -12 to 236).ConclusionStroke survivors undergoing inpatient rehabilitation spent approximately 20% of physical therapy actively engaged in walking practice. Those able to walk without assistance took more steps for longer, at a higher intensity.Trial registrationACTRN12613000764730 (https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=364545).

Project description:ImportanceFor walking rehabilitation after stroke, training intensity and duration are critical dosing parameters that lack optimization.ObjectiveTo assess the optimal training intensity (vigorous vs moderate) and minimum training duration (4, 8, or 12 weeks) needed to maximize immediate improvement in walking capacity in patients with chronic stroke.Design, setting, and participantsThis multicenter randomized clinical trial using an intent-to-treat analysis was conducted from January 2019 to April 2022 at rehabilitation and exercise research laboratories. Survivors of a single stroke who were aged 40 to 80 years and had persistent walking limitations 6 months or more after the stroke were enrolled.InterventionsParticipants were randomized 1:1 to high-intensity interval training (HIIT) or moderate-intensity aerobic training (MAT), each involving 45 minutes of walking practice 3 times per week for 12 weeks. The HIIT protocol used repeated 30-second bursts of walking at maximum safe speed, alternated with 30- to 60-second rest periods, targeting a mean aerobic intensity above 60% of the heart rate reserve (HRR). The MAT protocol used continuous walking with speed adjusted to maintain an initial target of 40% of the HRR, progressing up to 60% of the HRR as tolerated.Main outcomes and measuresThe main outcome was 6-minute walk test distance. Outcomes were assessed by blinded raters after 4, 8, and 12 weeks of training.ResultsOf 55 participants (mean [SD] age, 63 [10] years; 36 male [65.5%]), 27 were randomized to HIIT and 28 to MAT. The mean (SD) time since stroke was 2.5 (1.3) years, and mean (SD) 6-minute walk test distance at baseline was 239 (132) m. Participants attended 1675 of 1980 planned treatment visits (84.6%) and 197 of 220 planned testing visits (89.5%). No serious adverse events related to study procedures occurred. Groups had similar 6-minute walk test distance changes after 4 weeks (HIIT, 27 m [95% CI, 6-48 m]; MAT, 12 m [95% CI, -9 to 33 m]; mean difference, 15 m [95% CI, -13 to 42 m]; P = .28), but HIIT elicited greater gains after 8 weeks (58 m [95% CI, 39-76 m] vs 29 m [95% CI, 9-48 m]; mean difference, 29 m [95% CI, 5-54 m]; P = .02) and 12 weeks (71 m [95% CI, 49-94 m] vs 27 m [95% CI, 3-50 m]; mean difference, 44 m [95% CI, 14-74 m]; P = .005) of training; HIIT also showed greater improvements than MAT on some secondary measures of gait speed and fatigue.Conclusions and relevanceThese findings show proof of concept that vigorous training intensity is a critical dosing parameter for walking rehabilitation. In patients with chronic stroke, vigorous walking exercise produced significant and meaningful gains in walking capacity with only 4 weeks of training, but at least 12 weeks were needed to maximize immediate gains.Trial registrationClinicalTrials.gov Identifier: NCT03760016.

Project description:BACKGROUND:Although there are known clinical measures that may be associated with risk of future falls in older adults, we are still unable to predict when the fall will happen. Our objective was to determine whether unobtrusive in-home assessment of walking speed can detect a future fall. METHOD:In both ISAAC and ORCATECH Living Laboratory studies, a sensor-based monitoring system has been deployed in the homes of older adults. Longitudinal mixed-effects regression models were used to explore trajectories of sensor-based walking speed metrics in those destined to fall versus controls over time. Falls were captured during a 3-year period. RESULTS:We observed no major differences between those destined to fall (n = 55) and controls (n = 70) at baseline in clinical functional tests. There was a longitudinal decline in median daily walking speed over the 3 months before a fall in those destined to fall when compared with controls, p < .01 (ie, mean walking speed declined 0.1 cm s-1 per week). We also found prefall differences in sensor-based walking speed metrics in individuals who experienced a fall: walking speed variability was lower the month and the week just before the fall compared with 3 months before the fall, both p < .01. CONCLUSIONS:While basic clinical tests were not able to differentiate who will prospectively fall, we found that significant variations in walking speed metrics before a fall were measurable. These results provide evidence of a potential sensor-based risk biomarker of prospective falls in community living older adults.

Project description:Background:Physical activity is considered an effective measure to promote health in older people. There is evidence that the number of outdoor trips increases physical activity by increasing walking duration. The objective of this study was to analyse the relationship between daily time out-of-home and walking duration. Furthermore, predictors for walking duration and time out-of-home were evaluated. Methods:Walking duration was measured prospectively over a 1 week period by a body-fixed sensor and the time out-of-home was assessed by a questionnaire at the same days. Seven thousand, two hundred and forty-three days from 1289 older people (mean age 75.4 years) with both sensor-based measures and completed questionnaires were included in the analyses. To account for several observation days per participant multilevel regression analyses were applied. Analyses were stratified according to the time out-of-home (more or less than 100 min/day). Results:In the group with less than 100 min out-of-home, each additional minute out-of-home added 20 s to overall walking duration. If the time exceeded 100 min the additional increase of walking duration was only moderate or weak. Leaving the home once added 40 min of walking, the following trips 15 to 20 min. Increasing age, lower gait speed, comorbidities, low temperature, rain and specific week days (Sunday) decreased both the time out-of-home and walking duration. Other variables like gender (female), isolation or living with a spouse reduced the time out-of-home without affecting walking duration. Conclusions:Being out-of-home increases daily walking duration. The association is strongest if the time out-of-home is 100 min or less.

Project description:BackgroundA step cadence of 100 steps/minute is widely used to define moderate-intensity walking. However, the generalizability of this threshold to different populations needs further research. We investigate moderate-intensity step cadence values during treadmill walking and daily living in older adults.MethodsOlder adults (≥ 60 years) were recruited from urban community venues. Data collection included 7 days of physical activity measured by an activPAL3™ thigh worn device, followed by a laboratory visit involving a 60-min assessment of resting metabolic rate, then a treadmill assessment with expired gas measured using a breath-by-breath analyser and steps measured by an activPAL3™. Treadmill stages were undertaken in a random order and lasted 5 min each at speeds of 1, 2, 3, 4 and 5 km/h. Metabolic equivalent values were determined for each stage as standardised values (METSstandard) and as multiples of resting metabolic rate (METSrelative). A value of 3 METSstandard defined moderate-intensity stepping. Segmented generalised estimating equations modelled the association between step cadence and MET values.ResultsThe study included 53 participants (median age = 75, years, BMI = 28.0 kg/m2, 45.3% women). At 2 km/h, the median METSstandard and METSrelative values were above 3 with a median cadence of 81.00 (IQR 72.00, 88.67) steps/minute. The predicted cadence at 3 METSstandard was 70.3 (95% CI 61.4, 75.8) steps/minute. During free-living, participants undertook median (IQR) of 6988 (5933, 9211) steps/day, of which 2554 (1297, 4456) steps/day were undertaken in continuous stepping bouts lasting ≥ 1 min. For bouted daily steps, 96.4% (90.7%, 98.9%) were undertaken at ≥ 70 steps/minute.ConclusionA threshold as low as 70 steps/minute may be reflective of moderate-intensity stepping in older adults, with the vast majority of all bouted free-living stepping occurring above this threshold.

Project description:ImportanceThe relationship between self-reported walking limitation, a proxy of muscle function, and fracture risk has not been investigated.ObjectiveTo examine the association between a self-reported walking limitation of 1000 m or less and 5-year risk of fracture.Design, setting, and participantsThis prospective cohort study compared individuals with various degrees of walking ability limitation at 1000 m (a little limitation and a lot of limitation) and those without limitation (no limitation) accounting for age, falls, prior fractures, and weight. Participants from the ongoing population-based Sax Institute 45 and Up Study were followed from recruitment (2005-2008) for 5 years (2010-2013). Data analysis was conducted from July 2020 to September 2023.ExposureSelf-reported walking limitation.Main outcomes and measuresIncident fracture and site-specific fractures (hip, vertebral, and nonhip nonvertebral [NHNV] fractures).ResultsAmong the 266 912 participants enrolled in the 45 and Up Study, 238 969 were included, with 126 015 (53%) women (mean [SD] age, 63 [11] years) and 112 954 (47%) men (mean [SD] age, 61 [11] years). Approximately 20% reported a degree of limitation in walking 1000 m or less at baseline (39 324 women [24%]; 23 191 men [21%]). During a mean (SD) follow-up of 4.1 (0.8) years, 7190 women and 4267 men experienced an incident fracture. Compared with participants who reported no walking limitations, a little limitation and a lot of limitation were associated with higher risk of fracture (a little limitation among women: hazard ratio [HR], 1.32; 95% CI, 1.23-1.41; a little limitation among men: HR, 1.46; 95% CI, 1.34-1.60; a lot of limitation among women: HR, 1.60; 95% CI, 1.49-1.71; a lot of limitation among men: HR, 2.03; 95% CI, 1.86-2.22). Approximately 60% of fractures were attributable to walking limitation. The association was significant for hip, vertebral, and NHNV fracture and ranged between a 21% increase to a greater than 219% increase.Conclusions and relevanceIn this cohort study of 238 969 participants, self-reported walking limitations were associated with increased risk of fracture. These findings suggest that walking ability should be sought by clinicians to identify high-risk candidates for further assessment.

Project description:BackgroundFrailty and multimorbidity are common among patients in geriatric rehabilitation care (GRC). Proper care of these patients involves multiple professionals which requires optimal interprofessional collaboration to provide the best possible support. Interprofessional collaboration (IPC) goes beyond multi-professional collaboration. It requires professionals to think beyond the expertise of their own discipline and work on joint outcomes in which the patient is actively involved. This study describes the development of the GRC teams of an elderly care organization towards the IPC.MethodsMixed method pre-post study of 15 months. The interprofessional training program comprised team trainings, webinars, and online team sessions. Data was aggregated by administering the Extended Professional Identity Scale (EPIS) and QuickScan Interprofessional Collaboration (QS) measurements to GRC staff and by observations of the multi-professional team consultation (MPC) meetings of six GRC teams of an organization for elderly care in Drachten and Dokkum in the Netherlands. ADL independence (Barthel Index) and number of inpatient days were analyzed before and after the project.ResultsPretest healthcare professional response was 106, patients for analyses was 181; posttest response was 84, patients was 170. The EPIS shows improvement on "interprofessional belonging" (P = .001, 95%CI: 0.57-2.21), "interprofessional commitment" (P = .027, 95%CI: 0.12-1.90), and overall "interprofessional identity" (P = .013, 95%CI: 0.62 - 5.20). On the QS, all domains improved; "shared values" (P = .009, 95%CI: 0.07 - 0.47), "context" (P = .005, 95%CI: 0.08 - 0.44), "structure & organization" (P = .001, 95%CI: 0.14 - 0.56), "group dynamics & interaction" (P < .001, 95%CI: 0.18 - 0.58), and "entrepreneurship & management" (P = .039, 95%CI: 0.01 - 0.48). A qualitative analysis of the reflection responses and MPC observations indicate a shift from multi-professional to more IPC. Differences in ADL over time were not statistically significant. The mean number of inpatient days was reduced by 11.8 (P < .001, 95%CI: -17.34 - - 6.31) days.ConclusionsWithin the GRC teams, there was a shift observed to more IPC and better representation of the patient's wishes and needs. ADL independence did not change, yet we found a statistically significant decrease in the number of inpatient days. The basis for IPC was well established, however, it remains necessary that the teams continue to develop and invest in the collaboration with each other and the patient to further improve it.

Project description:BACKGROUND:Geriatric syndromes such as falls, frailty, and functional impairment are multifactorial conditions used to identify vulnerable older adults. Limited data exist on these conditions in older HIV-infected adults, and no studies have comprehensively examined these conditions. METHODS:Geriatric syndromes including falls, urinary incontinence, functional impairment, frailty, sensory impairment, depression, and cognitive impairment were measured in a cross-sectional study of HIV-infected adults aged 50 years and older who had an undetectable viral load on antiretroviral therapy. We examined both HIV and non-HIV-related predictors of geriatric syndromes including sociodemographics, number of comorbidities and nonantiretroviral medications, and HIV-specific variables in multivariate analyses. RESULTS:We studied 155 participants with a median age of 57 (interquartile range: 54-62) and 94% were men. Prefrailty (56%), difficulty with instrumental activities of daily living (46%), and cognitive impairment (47%) were the most frequent geriatric syndromes. Lower CD4 nadir incidence rate ratio [IRR: 1.16, 95% (confidence interval) CI: 1.06 to 1.26], non-white race (IRR: 1.38, 95% CI: 1.10 to 1.74), and increasing number of comorbidities (IRR: 1.09, 95% CI: 1.03 to 1.15) were associated with increased risk of having more geriatric syndromes. CONCLUSIONS:Geriatric syndromes are common in older HIV-infected adults. Treatment of comorbidities and early initiation of antiretroviral therapy may help to prevent development of these age-related complications. Clinical care of older HIV-infected adults should consider incorporation of geriatric principles.

Project description:Dietary proteins are sources of some amino acid precursors of two neurotransmitters relevant for biological rhythms, serotonin and melatonin, which are involved in sleep and alertness. Meat is the main source of proteins in many countries. Furthermore, meat consumption is of special interest because it provides high-quality protein as well as saturated and trans fatty acids. However, its effect on sleep patterns is unclear. Thereby, the aim was to examine the association of habitual meat consumption with changes in sleep duration and with sleep quality in older adults. We used data from 1,341 participants in the Seniors-ENRICA cohort aged ≥60 years, followed from 2012 through 2015. Habitual meat consumption was assessed at baseline with a validated diet history. Sleep duration and quality were ascertained both in 2012 and 2015. Analyses were performed with logistic regression and adjusted for socio-demographic variables, lifestyle, morbidity, sleep duration and poor sleep indicators at baseline. During follow-up, 9.0% of individuals increased and 7.9% decreased their sleep duration by ≥2 hours/night. Compared with individuals in the lowest tertile of meat consumption (<87 g/d), those in the highest tertile (≥128 g/d) showed increased incidence of a large decrease (≥2 h) in sleep duration (OR: 1.93; 95% CI:1.01-3.72; p-trend:0.04). Higher consumption of meat was also associated with incidence of snoring (OR:2.06; 95% CI:1.17-3.60; p-trend:0.01) and poor general sleep quality (OR:1.71; 95% CI:1.04-2.82; p-trend:0.03). Each 100 g/d increment in meat intake was associated with a 60% higher risk of both large sleep duration changes and poor sleep quality (OR:1.60; 95% CI:1.07-2.40). Results were in the same direction for red and processed meat and for white meat separately, and among individuals with physical impairment. Higher meat consumption (≥128 g/d) was associated with changes in sleep duration and with poor sleep in older adults.

Project description:Previous studies have shown that more active older adults have better cognition and brain health based on a variety of structural neuroimaging measures. Nevertheless, the effects of maintaining physical activity (PA) over an extended period of time on future changes in older adults' cognition and brain structure are unknown. Participants were 141 initially well-functioning community-dwelling older adults (aged 70-79 years at baseline; 60% female; 42% black) studied over a 13-year period. PA (self-reported time spent walking) was assessed annually from years 1 to 10. Magnetic resonance imaging with diffusion tensor was performed at years 10 and 13. Time spent walking decreased on average by 8.4% annually from year 1 to year 10. Independent of initial time spent walking, demographics, and APOE e4 status, better maintenance of time spent walking over the decade predicted less reduction in hippocampal volume (p = 0.03), smaller increases in global gray matter mean diffusivity and white matter axial diffusivity (p < 0.01), and maintenance of general cognitive performance (p < 0.01). Maintenance of cognitive performance was associated with smaller increases in white matter axial diffusivity (p < 0.01). PA at baseline and at year 10, as well as changes in PA over a 5-year period, was less predictive of future changes in brain structure and cognition. Thus, how PA levels change over longer periods of aging may be an important contributor to cognitive and neural protection.
