[PMID: 39015007 DOI: 10.1080/09593985.2024.2377752] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 07/03/2024] [Indexed: 07/18/2024]
Abstract
BACKGROUND Ankle osteoarthritis (OA) is a disease involving pain and decreased physical function which can attenuate the tolerance to perform high-load resistance training. Low-load blood flow restriction (BFR) training has been demonstrated to improve muscle strength, muscle size, and physical function in patients suffering from OA. OBJECTIVE We examined the effects of 12 weeks of BFR-training performed 4 times a week in an individual with Kellgren-Lawrence (KL) grade 4 ankle OA. CASE DESCRIPTION A 32-year-old woman with KL grade 4 right ankle OA subsequent to a clubfoot repair in childhood performed 12 weeks of BFR-training. Four exercises with concurrent blood flow restriction (60% of arterial occlusion pressure) targeting the lower leg were performed 4 times/week. The following outcome measures were collected at baseline and 12 weeks after BFR-training: The Foot and Ankle Outcome Score (FAOS), calf circumference, maximal isometric muscle strength, single-leg heel raise test, single-leg stance test, and lateral side-hop test. OUTCOMES Adherence to the training was 93.75%. The patient demonstrated improvements in FAOS subscale symptoms, pain, and sports/recreational activities by 19-47 points (minimal detectable change (MDC) = 18-21.5 points); maximal muscle strength in plantarflexion (36%), eversion (55%), and inversion (38%) (MDC for plantarflexion = 16.81-29.97%). The single-leg heel raise test and the lateral side-hop test improved with 66% and 51%, respectively. Calf circumference was maintained. CONCLUSION BFR-training improved patient-reported outcomes, lower leg muscle strength, and physical function in an individual suffering from KL grade 4 ankle OA following childhood clubfoot repair.

Nutrition interventions for body composition, physical function, cognition in hospitalized older adults: A systematic review of individuals 75 years and older. J Am Geriatr Soc 2024; 72:2206-2218. [PMID: 38376064 PMCID: PMC11226365 DOI: 10.1111/jgs.18799] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 12/01/2023] [Accepted: 01/21/2024] [Indexed: 02/21/2024]
Abstract
BACKGROUND Globally, the oldest old population is expected to triple by 2050. Hospitalization and malnutrition can result in progressive functional decline in older adults. Minimizing the impact of hospitalization on functional status in older adults has the potential to maintain independence, reduce health and social care costs, and maximize years in a healthy state. This study aimed to systematically review the literature to identify nutritional interventions that target physical function, body composition, and cognition in the older population (≥ 75 years). METHODS A systematic review was conducted to evaluate the efficacy of nutritional interventions on physical function, body composition, and cognition in adults aged ≥ 75 years or mean age ≥80 years. Searches of PubMed (National Institutes of Health, National Library of Medicine), Scopus (Elsevier), EMBASE (Elsevier), Cumulative Index to Nursing and Allied Health Literature (CINAHL) with Full Text (EBSCOhost), and PsycInfo (EBSCOhost) were conducted. Screening, data extraction, and quality assessment were performed in duplicate and independently (CRD42022355984; https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=355984). RESULTS Of 8311 citations identified, 2939 duplicates were excluded. From 5372 citations, 189 articles underwent full-text review leaving a total of 12 studies for inclusion. Interventions were food-based, protein-based, carbohydrate-based, personalized, or used parenteral nutrition. Ten studies monitored anthropometric or body composition changes with three showing maintenance or improvements in lean mass, body mass index, triceps skinfold, and mid-upper arm circumference compared with the control group. Six studies monitored physical function but only the largest study found a beneficial effect on activities of daily living. Two of three studies showed the beneficial effects of nutritional intervention on cognition. CONCLUSION There are few, high-quality, nutrition-based interventions in older adults ≥75 years. Despite heterogeneity, our findings suggest that large, longer-term (>2 weeks) nutritional interventions have the potential to maintain body composition, physical function, and cognition in adults aged 75 years and older during hospitalization.

Abstract
BACKGROUND AND PURPOSE Individuals with downbeat nystagmus (DBN) syndrome present with DBN, dizziness, blurred vision, and unsteady gait. Pharmacological intervention with 4-aminopyridine (4-AP) may be effective in improving oculomotor function, but there is minimal evidence to date that it improves gait. This suggests the possible benefit of combining pharmacotherapy with physical therapy to maximize outcomes. This case report documents improvements in gait and balance after physical therapy and aminopyridine (AP) in an individual with DBN syndrome. CASE DESCRIPTION The patient was a 70-year-old man with a 4-year history of worsening dizziness and imbalance, diagnosed with DBN syndrome. He demonstrated impaired oculomotor function, dizziness, and imbalance, which resulted in falls and limited community ambulation. INTERVENTION The patient completed a customized, tapered course of physical therapy over 6 months. Outcome measures included the 10-meter walk test, the Timed Up and Go (TUG), the Dynamic Gait Index (DGI), and the modified clinical test of sensory integration and balance. OUTCOMES Improvements exceeding minimal detectable change were demonstrated on the TUG and the DGI. Gait speed on the 10-meter walk test did not change significantly, but the patient was able to use a cane to ambulate in the community and reported no further falls. DISCUSSION Controlled studies are needed to explore the potential for AP to augment physical therapy in people with DBN syndrome. Physical therapists are encouraged to communicate with referring medical providers about the use of AP as pharmacotherapy along with physical therapy for individuals with DBN syndrome.

Abstract
BACKGROUND Falls are a leading cause of severe injury and death in older adults. Remote screening of fall risk may prevent falls and hence, advance health and wellness of older adults. While remote health care is becoming a common practice, we question if remote evaluation of fall risk is as reliable as face-to-face (FTF). OBJECTIVE To assess the inter-tester reliability of synchronized remote and FTF fall risk assessment. METHODS This inter-format, inter-rater reliability study included 48 home dwelling older adults aged 65 and over. Five valid functional and balance tests were conducted: 30 Second Sit-to-Stand (STS), MiniBESTest, Timed up and go (TUG), 4-Meter Walk (4MWT), and Berg Balance Scale (BBS). Instructions were provided via videoconferencing, and two physiotherapists scored performance simultaneously, one remotely, and one in the room. Inter-rater reliability between remote and FTF scores was analyzed using intraclass correlation coefficient (ICC2,1), standard error of measurement (SEM), minimal detectable change (MDC95) and Bland and Altman analysis. RESULTS Excellent ICCs were found for STS, MiniBESTest, TUG, and BBS (0.90-0.99), and moderate for 4MWT (0.74). SEM and MDC95 values were STS (0.37,1.03 repetitions), MiniBESTest (1.43,3.97 scores), TUG (1.22,3.37 seconds), 4MWT (0.17,0.47 m/second), and BBS (1.79,4.95 scores). The Bland and Altman analysis showed excellent agreement between remote and FTF assessments of the STS. All other tests showed low to moderate agreement. Mean difference ± SD and 95%LOA were as follows: STS (-0.11 ± 0.52), (-1.13,0.91) repetitions, MiniBESTest (0.45 ± 1.98), (-3.43,4.32) scores, TUG (-0.35 ± 1.54), (-3.37,2.67) seconds, 4MWT (-0.08 ± 0.22), (-0.35,0.51) meter/second, and BBS (0.04 ± 2.53), (-4.93,5.01) scores. CONCLUSIONS The findings support the responsible integration of remote fall risk assessment in clinical practice, enabling large-scale screenings and referrals for early intervention to promote healthy aging and fall prevention.

Geriatrics (Basel) 2024; 9:79. [PMID: 38920435 PMCID: PMC11202539 DOI: 10.3390/geriatrics9030079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2024] [Revised: 06/03/2024] [Accepted: 06/06/2024] [Indexed: 06/27/2024] Open
Abstract
Previous research has found that lower limb muscle asymmetries increase with age and are linked to fall and injury risks. However, past studies lack a wide variety of muscle function modes and measures as well as comparison to a comparable younger age group. The purpose of this study was to examine age-related lower limb muscle function asymmetries across a variety of muscle action types and velocities in young and old adults. Lower limb balance, strength, power, and velocity were evaluated with concentric, isometric, isotonic, and eccentric muscle actions during a single-leg stance test and on single- and multi-joint dynamometers in 29 young (age = 21.45 ± 3.02) and 23 old (age = 77.00 ± 4.60) recreationally active men and women. Most (15 of 17) variables showed no statistical (p > 0.05) or functional (10% threshold) limb asymmetry for either age group. There was a significant main effect (p = 0.046; collapsed across groups) found for asymmetry (dominant > non-dominant) for the isotonic peak velocity variable. There was a significant (p = 0.010) group × limb interaction for single-joint concentric peak power produced at a slow (60 deg/s) velocity due to the non-dominant limb of the young group being 12.2% greater than the dominant limb (p < 0.001), whereas the old group was not asymmetrical (p = 0.965). The findings of this investigation indicate there is largely no age-related asymmetry of the lower limbs across a range of muscle function-related variables and modes, with a couple of notable exceptions. Also, the significant asymmetries for the isotonic peak velocity variable perhaps show the sensitivity of this uncommonly used measure in detecting minimally present muscle function imbalances.

Abstract
OBJECTIVES The first objective was to evaluate clinical data from a multi-component fall prevention program. The second objective was to explore the relationship between physical function and fear of falling (FoF). METHODS Adults (N = 287, mean age = 76 years) who participated in the Building Balance Program between 2011-2020 were assessed with five physical function measures and two FoF measures. Repeated measures ANOVA controlling for age and sex were performed to assess change from baseline. Linear regressions were conducted to evaluate how physical function explained variations in FoF. RESULTS There were significant improvements between pre and post-program Berg Balance Scale (BBS) scores (p < .001), Timed-Up and Go (TUG) times (p < .001), 30 second Chair-Stand (30 CST repetitions) (p < .001), Functional Reach (FR) distance (p < .001), gait speed (p < .001), single item-FoF score (p < .001), and short Falls Efficacy Scale-International (FES-I score) (p < .001). After controlling for sex on all regression analyses, age, and pre-program gait speed explained variations in pre-program short FES-I scores (Adjusted R2 = 0.19). Age, pre-program BBS and 30 CST repetitions explained variations in pre-program level of FoF (Adjusted R2 = 0.25). Variations in post-program short FES-I scores (Adjusted R2 = 0.17) were explained by age, post-program TUG times and FR distance after controlling for age and sex. Robust regressions indicated variations in post-program level of FoF explained by age, post-program TUG and FR distance with a two-way interaction between age and FR. CONCLUSION A multi-component fall prevention program improved physical function and decreased FoF. A small association between physical function and FoF similar between pre- and post-program conditions was identified.

Abstract
BACKGROUND This review provides an overview of the psychometric properties of the short physical performance battery (SPPB), timed up and go test (TUG), 4 m gait speed test (4 m GST) and the 400 m walk test (400 m WT) in community-dwelling older adults. METHODS A systematic search was conducted in MEDLINE, CINAHL and EMBASE, resulting in the inclusion of 50 studies with data from in total 19,266 participants (mean age 63.2-84.3). Data were extracted and properties were given a sufficient or insufficient overall rating following the COSMIN guideline for systematic reviews of patient-reported outcome measures. Quality of evidence (QoE) was rated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS The SPPB was evaluated in 12 studies, TUG in 30, 4 m GST in 12 and 400 m WT in 2. Reliability of the SPPB, TUG and 4 m GST was rated sufficient (moderate to good QoE). The measurement error of the SPPB was rated insufficient (low QoE). Criterion validity for the SPPB was insufficient in indicating sarcopenia (moderate QoE), while the TUG was sufficient and insufficient for determining mobility limitations (low QoE) and activities of daily living disability (low QoE), respectively. Construct validity of the SPPB, TUG, 4 m GST and 400 m WT was rated insufficient in many constructs (moderate to high QoE). Responsiveness was rated as insufficient for SPPB (high QoE) and TUG (very low QoE), while 4 m GST was rated as sufficient (high QoE). CONCLUSION Overall, the psychometric quality of commonly used physical performance tests in community-dwelling older adults was generally rated insufficient, except for reliability. These tests are widely used in daily practice and recommended in guidelines; however, users should be cautious when drawing conclusions such as sarcopenia severity and change in physical performance due to limited psychometric quality of the recommended measurement instruments. There is a need for a disease-specific physical performance test for people with sarcopenia.This research received no specific grant from any funding agency and was registered a priori using the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42022359725).

Abstract
Awareness of the prevalence of osteoporosis and fractures across jurisdictions can guide the development of local preventive programs and healthcare policies. We observed geographical variations in total hip bone mineral density and in the prevalence of major osteoporotic fractures across Canadian provinces, which persisted after adjusting for important covariates. PURPOSE We aimed to describe sex-specific total hip bone mineral density (aBMD) and prevalent major osteoporotic fractures (MOF) variation between Canadian provinces. METHODS We used baseline data from 21,227 Canadians (10,716 women, 10,511 men) aged 50-85 years in the Canadian Longitudinal Study on Aging (CLSA; baseline: 2012-2015). Linear and logistic regression models were used to examine associations between province of residence and total hip aBMD and self-reported MOF, stratified by sex. CLSA sampling weights were used to generate the prevalence and regression estimates. RESULTS The mean (SD) age of participants was 63.9 (9.1) years. The mean body mass index (kg/m2) was lowest in British Columbia (27.4 [5.0]) and highest in Newfoundland and Labrador (28.8 [5.3]). Women and men from British Columbia had the lowest mean total hip aBMD and the lowest prevalence of MOF. Alberta had the highest proportion of participants reporting recent falls (12.0%), and Manitoba (8.4%) the fewest (p-value=0.002). Linear regression analyses demonstrated significant differences in total hip aBMD: women and men from British Columbia and Alberta, and women from Manitoba and Nova Scotia had lower adjusted total hip aBMD than Ontario (p-values<0.02). Adjusted odds ratios (95% confidence intervals, CI) for prevalent MOF were significantly lower in women from British Columbia (0.47 [95% CI: 0.32; 0.69]) and Quebec (0.68 [95% CI: 0.48; 0.97]) and in men from British Columbia (0.40 [95% CI:0.22; 0.71]) compared to Ontario (p-values<0.03). Results were similar when adjusting for physical performance measures and when restricting the analyses to participants who reported White race/ethnicity. CONCLUSION Geographical variations in total hip aBMD and in the prevalence of MOF between provinces persisted after adjusting for important covariates which suggests an association with unmeasured individual and environmental factors.

Abstract
OBJECTIVE The gait speed test is one of the most widely used mobility assessments for older adults. We conducted a systematic review to evaluate and compare the measurement properties of the usual and fast gait speed tests in community-dwelling older adults. METHODS Three databases were searched: MEDLINE, EMBASE and CINAHL. Peer-reviewed articles evaluating the gait speed test's measurement properties or interpretability in community-dwelling older adults were included. The Consensus-based Standards for the selection of health Measurement Instruments guidelines were followed for data synthesis and quality assessment. RESULTS Ninety-five articles met our inclusion criteria, with 79 evaluating a measurement property and 16 reporting on interpretability. There was sufficient reliability for both tests, with intraclass correlation coefficients (ICC) generally ranging from 0.72 to 0.98, but overall quality of evidence was low. For convergent/discriminant validity, an overall sufficient rating with moderate quality of evidence was found for both tests. Concurrent validity of the usual gait speed test was sufficient (ICCs = 0.79-0.93 with longer distances) with moderate quality of evidence; however, there were insufficient results for the fast gait speed test (e.g. low agreement with longer distances) supported by high-quality studies. Responsiveness was only evaluated in three articles, with low quality of evidence. CONCLUSION Findings from this review demonstrated evidence in support of the reliability and validity of the usual and fast gait speed tests in community-dwelling older adults. However, future validation studies should employ rigorous methodology and evaluate the tests' responsiveness.

Abstract
This study aimed to assess the feasibility and reliability of quadriceps maximal short-term power (Pmax) and corresponding optimal movement velocity (υopt-velocity at which the power reaches a maximum value) measurements in different populations of subjects. Five groups of subjects, fifty participants in each group, took part in the study: students; patients of the cardiac rehabilitation program; patients after stroke; older adults; and subjects of different ages who performed repetitive measurements with two different bicycles. The correlations calculated for the pairs of scores ranged from 0.93 to 0.99 for Pmax and from 0.86 to 0.96 for υopt (all with p < 0.001). Intraclass Correlations Coefficients (ICCs) varied from 0.93 to 0.98 for Pmax and from 0.86 to 0.95 for υopt. The standard error of measurement (SEM) varied from 16.9 to 21.4 W for Pmax and from 2.91 to 5.54 rotations(rot)/min for υopt. The coefficients of variation (CVs or SEM%) for Pmax and υopt in the stroke group were 10.6% and 11.4%, respectively; all other CVs were clearly lower than 10%. The minimal detectable change (MDC) varied from 46.6 to 59.3 W for Pmax and from 8.07 to 15.4 rot/min for υopt. MDC% varied from 9.53% to 29.3% for Pmax and from 8.19% to 31.7% for υopt, and was the highest in the stroke group. Therefore, the precision of measurements of Pmax and υopt was confirmed by very good indices of absolute and relative reliability. The proposed methodology is precise, safe, not time-consuming and feasible in older subjects and those with diseases.

Associations between Osteosarcopenia and Falls, Fractures, and Frailty in Older Adults: Results From the Canadian Longitudinal Study on Aging (CLSA). J Am Med Dir Assoc 2024; 25:167-176.e6. [PMID: 37925161 DOI: 10.1016/j.jamda.2023.09.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 09/22/2023] [Accepted: 09/25/2023] [Indexed: 11/06/2023]
Abstract
OBJECTIVE To explore if older adults with osteosarcopenia are at a greater risk of falls, fractures, frailty, and worsening life satisfaction and activities of daily living (ADL) compared to those with normal bone mineral density (BMD) and without sarcopenia. DESIGN The baseline and 3-year follow-up of a longitudinal study. SETTING AND PARTICIPANTS Community-dwelling people aged 65 years or older in Canada. METHODS Caucasian participants 65 years or older that completed the Canadian Longitudinal Study on Aging (CLSA) 2015 baseline interview, physical measurements and 3-year follow-up were included. Osteopenia/osteoporosis was defined as BMD T score below -1 SD according to the World Health Organization, and sarcopenia was defined as low grip strength and/or low gait speed according to the Sarcopenia Definition Outcomes Consortium. Osteosarcopenia was defined as the coexistence of osteopenia/osteoporosis and sarcopenia. Self-reported incident falls and fractures in the last 12 months before the 3-year follow-up were measured. Frailty was assessed through the Rockwood Frailty Index (FI); life satisfaction through the Satisfaction With Life Scale (SWLS); and ADL through the Older American Resources and Services modules. Multivariable logistic and linear regression, including subgroup analyses by sex, were conducted. RESULTS The sample of 8888 participants (49.1% females) had a mean age (SD) of 72.7 (5.6) years. At baseline, neither osteopenia/osteoporosis nor sarcopenia (reference group) was present in 30.1%, sarcopenia only in 18.4%, osteopenia/osteoporosis only in 29.2%, and osteosarcopenia in 22.3%. Osteosarcopenia was significantly associated with incident falls and fractures in males [adjusted odds ratio (aOR), 1.90, 95% CI 1.15, 3.14, and aOR 2.60, 95% CI 1.14, 5.91, respectively] compared to males without osteopenia/osteoporosis or sarcopenia. Participants with osteosarcopenia had worsening ADL of 0.110 (estimated β coefficient 0.110, 95% CI 0.029, 0.192) and a decrease in their SWLS by 0.660 (estimated β coefficient -0.660, 95% CI -1.133, -0.187), compared to those without. Osteosarcopenia was not associated with frailty for both males and females. CONCLUSIONS AND IMPLICATIONS Osteosarcopenia was associated with self-reported incident falls and fractures in males and worse life satisfaction and ADL for all participants. Assessing and identifying osteosarcopenia is essential for preventing falls and fractures. Furthermore, it improves life satisfaction and ADL.

Sarcopenia Definition and Outcomes Consortium 2020 Definition: Association and Discriminatory Accuracy of Sarcopenia With Disability in the Canadian Longitudinal Study on Aging. J Gerontol A Biol Sci Med Sci 2023; 78:1597-1603. [PMID: 37227983 DOI: 10.1093/gerona/glad131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Indexed: 05/27/2023] Open
Abstract
BACKGROUND Previous sarcopenia definitions have poor discriminatory accuracy for identifying people with/without relevant health outcomes, and poor agreement between methods of operationalizing sarcopenia criterion. The 2020 Sarcopenia Definitions and Outcomes Consortium (SDOC) definition recommends grip strength (absolute, or standardized to body mass index, total body fat, lean arm mass, or weight), and gait speed. The agreement between methods of operationalizing grip strength and discriminatory accuracy of the SDOC definition for health outcomes such as activities of daily living (ADL) disability is unknown. METHODS Cross-sectional analyses of 27 924 Canadian Longitudinal Study on Aging participants aged 45-85 at baseline (2012-2015) stratified by sex. The associations of the SDOC definitions with ADL disability were assessed using logistic regression. Area under the curve (AUC) analyses were conducted to assess discriminatory accuracy. Agreement between methods of operationalizing grip strength was measured using Cohen's kappa. RESULTS Sarcopenia was associated with 1.60 (1.42-1.80) to 5.80 (4.89-6.88) greater odds of ADL disability with AUC values between 0.60 and 0.81. Agreement between methods of operationalizing grip strength was between 0.10-0.80 for grip strength alone and 0.45-0.91 when combined with gait speed. CONCLUSIONS The SDOC-suggested criteria of grip strength and gait speed are significantly associated with ADL disability and have high discriminatory accuracy. However, the agreement between methods of operationalizing grip strength tended to be modest, and AUC, sensitivity, and specificity differed depending on the definition. We suggest a single measure of grip strength be considered and age-stratified cutoff values to improve AUC values.

J Clin Med 2023; 12:jcm12082971. [PMID: 37109307 PMCID: PMC10146369 DOI: 10.3390/jcm12082971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 03/16/2023] [Accepted: 04/17/2023] [Indexed: 04/29/2023] Open
Abstract
BACKGROUND Clinical guidelines recommend prehabilitation with exercise training to optimize recovery after lung cancer surgery. However, the lack of access to facility-based exercise programs is a major barrier to routine participation. This study aimed to assess the feasibility of a home-based exercise intervention before lung cancer resection. METHODS We conducted a prospective, two-site feasibility study, including patients scheduled for lung cancer surgery. Exercise prescription involved aerobic and resistance training with telephone-based supervision. The primary endpoint was overall feasibility (recruitment rate, retention rate, intervention adherence and acceptability). Secondary endpoints included safety and effects on health-related quality of life (HRQOL) and physical performance, evaluated at baseline, after the exercise intervention and 4-5 weeks after surgery. RESULTS Over three months, 15 patients were eligible, and all agreed to participate (recruitment rate: 100%). A total of 14 patients completed the exercise intervention, and 12 patients were evaluated postoperatively (retention rate: 80%). The median length of the exercise intervention was 3 weeks. Patients performed an aerobic and resistance training volume higher than prescribed (median adherence rates of 104% and 111%, respectively). A total of nine adverse events occurred during the intervention (Grade 1, n = 8; Grade 2, n = 1), the most common being shoulder pain. After the exercise intervention, significant improvements were observed in the HRQOL summary score (mean difference, 2.9; 95% confidence interval [CI], from 0.9 to 4.8; p = 0.049) and the five-times sit-to-stand test score (median difference, -1.5; 95% CI, from -2.1 to -0.9; p = 0.001). After surgery, no significant effects on HRQOL and physical performance were observed. CONCLUSION A short-term preoperative home-based exercise intervention is feasible before lung cancer resection and may enhance accessibility to prehabilitation. Clinical effectiveness should be investigated in future studies.

Measuring physical performance in later life: reliability of protocol variations for common performance-based mobility tests. Aging Clin Exp Res 2023; 35:1087-1096. [PMID: 37004707 DOI: 10.1007/s40520-023-02384-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 03/04/2023] [Indexed: 04/04/2023]
Abstract
BACKGROUND AND AIMS Performance-based tests of mobility or physical function such as the Timed Up and Go (TUG), gait speed, chair-rise, and single-leg stance (SLS) are often administered using different protocols in aging populations, however, the reliability of their assessment protocols is not often considered. The purpose of this study was to examine the reliabilities of frequently used assessment protocols for the TUG, gait speed, chair-rise, and SLS in different age groups. METHODS We administered the following assessment protocols in an age-stratified (50-64, 65-74, 75+ years) sample of participants (N = 147) from the Canadian Longitudinal Study on Aging (CLSA): TUG fast pace and TUG normal pace: TUG-cognitive counting backwards by ones and counting back by threes, gait speed with 3-m and 4-m course, chair-rise with arms crossed and allowing the use of arms, and SLS using preferred leg or both legs-on two occasions within 1 week. We assessed the relative (intra-class correlation) and absolute reliability (standard error of measurement, SEM and minimal detectable change, MDC) for each protocol variation and provided recommendations based on relative reliability. RESULTS For participants aged 50-64 years, our results suggest better reliability for TUG fast-pace compared with normal-pace (ICC and 95% CI 0.70; 0.41-0.85 versus 0.38; 0.12-0.59). The reliability values for 3-m gait speed were potentially higher than for 4-m gait speed (ICC 0.75; 0.67-0.82 versus 0.64; 0.54-0.73) and values for chair-rise suggested better reliability allowing participants to use their arms than with arms crossed (ICC 0.79; 0.66-0.86 versus 0.64; 0.45-0.77) for participants overall. For participants aged 75+ years, ICCs for SLS with the preferred leg showed better reliability than for both legs (ICC = 0.62-0.79 versus 0.30-0.39). CONCLUSIONS AND DISCUSSION These reliability data and the recommendations can help guide the selection of the most appropriate performance-based test protocols for measuring mobility in middle-aged and older community-dwelling adults.

Normative values for grip strength, gait speed, timed up and go, single leg balance, and chair rise derived from the Canadian longitudinal study on ageing. Age Ageing 2023; 52:afad054.

Abstract
BACKGROUND decreased muscle strength and physical function often precede disability, nursing home admission, home care use and mortality in older adults. Normative values for commonly used physical performance-based tests are not widely available for older adults but are required for clinicians and researchers to easily identify individuals with low performance. OBJECTIVE to develop normative values for grip strength, gait speed, timed up and go, single-leg balance and five-repetition chair rise tests in a large population-based sample of Canadians aged 45-85 years. METHODS baseline data (2011-2015) from the Canadian Longitudinal Study on Ageing was used to estimate age- and sex-specific normative values for each of the physical tests. Participants were without disability or mobility limitation (no assistance with activities of daily living or use of mobility devices). RESULTS of the 25,470 participants eligible for the analyses 48.6% (n = 12,369) were female with a mean age of 58.6 ± 9.5 years. Sex-specific 5th, 10th, 20th, 50th, 80th, 90th and 95th percentile values for each physical performance-based test were estimated. Cross-validation (n = 100 repetitions) with a 30% holdout sample was used to evaluate model fit. CONCLUSIONS the normative values developed in this paper can be used in clinical and research settings to identify individuals with low performance relative to their peers of the same age and sex. Interventions targeting these at-risk individuals including physical activity can prevent or delay mobility disability and the resulting cascade of increasing care requirements, health care costs and mortality.

Abstract
Introduction Digital dynamometers to assess grip strength are becoming more common in research and clinical settings. The aim of the study was to assess validity and reliability of the K-force dynamometer compared to the Jamar dynamometer. We also aimed to assess differences over the course of three measurements. Methods Twenty-seven healthy participants were included. Three trials with the K-force and Jamar dynamometers were completed. Testing order was randomised. Intraclass correlation coefficients (ICCs) with absolute agreement assessed reliability and validity. Standard error of the measurement (SEM) and minimal detectable change (MDC95) were calculated. Concurrent validity was assessed using Pearson's correlations and ICCs. Differences between the three repetitions were assessed using one-way repeated measures ANOVAs. Results Both the K-force and the Jamar presented excellent intra-rater reliability with ICCs ranging from 0.96 to 0.97. The SEM ranged from 1.7 to 2 kg and the MDC from 4.7 to 5.7 kg for both dynamometers. The concurrent validity of the K-force was high (r ≥ 0.89). However, the K-force underestimated the grip strength by 4.5-8.5 kg. There was no change in grip strength with either dynamometer over the course of three trials. Conclusions The K-force is reliable, but it underestimates grip strength by 4.5-8.5 kg compared to the Jamar dynamometer. K-force can be used to monitor progress over time but cannot be used to compare results against normative data. The use of a single measurement when assessing grip strength is sufficient when assessing healthy subjects.

Abstract
PURPOSE To understand the relationship between ambient air pollution and the onset of balance problems. DESIGN Population-based prospective cohort study. METHODS Baseline and 3-year follow-up data were used from the Canadian Longitudinal Study on Aging. The Comprehensive Cohort included adults aged 45-85 years old recruited from 11 sites across 7 provinces. Data on air pollution came from the Canadian Urban Environmental Health Research Consortium. Annual mean levels of ozone, fine particulate matter (PM2.5), and sulfur dioxide for each participant's postal code were estimated from satellite data. Balance was measured at both time points using the one-leg balance test with those who could not stand on one leg for at least 60 s defined as failing the balance test. Our outcome was the new development of failing the balance test at follow-up in those who passed the balance test at baseline. Logistic regression was used. RESULTS Of the 12,158 people who could stand for 60 s on one leg at baseline, 18% were unable to do so 3 years later. In single pollutant models, living in an area with higher ozone levels was associated with the 3-year onset of balance problems (odds ratio (OR) = 1.13 per interquartile range of ozone, 95% CI 1.02, 1.24) after adjustment for demographic, lifestyle, and health variables. In a multipollutant model, the association with ozone increased slightly (OR = 1.16, 95% CI 1.04, 1.30). There were no associations with PM2.5 or sulfur dioxide. CONCLUSION Our findings provide longitudinal evidence that higher ozone levels are associated with the odds of developing balance problems over a 3-year period. Further work should attempt to confirm our findings and explore the potential mechanism of action.

Abstract
Objective We investigated the impact of using a companion robot on the mental state of a community-dwelling older adult who was receiving home-visit rehabilitation services during the state of emergency for coronavirus disease 2019 (COVID-19). Methods This case involved an 80-year-old woman with compression fractures of lumbar vertebrae 1 and 2. Her medical history included hypothyroidism, hypertension, dyslipidemia, and depression. The companion robot used was Smibi®, a healing baby robot that responds in various ways depending on how the user interacts with it. The patient interacted (e.g., hugging, conversing) with Smibi® for 30 minutes per day for 1 month, from April 2020 (immediately before the declaration of a state of emergency in Japan) to May 2020. The patient was evaluated with the Self-Rating Depression Scale (SDS) before and after using Smibi®. Results The SDS score decreased from 37 points to 26 points after the use of Smibi®. The items related to diurnal variation, sleep, despair about the future, and dissatisfaction decreased by 2-3 points. Conclusion Our findings suggest that interacting with Smibi® may improve depression in older adults who have been forced to refrain from going out due to the spread of COVID-19. Future studies with long-term follow-up and large sample sizes are required to confirm the effectiveness of companion robots in improving depression among community-dwelling older adults.

Abstract
Background Assessment of reliability is one of the key components of the validation process designed to demonstrate that a novel clinical measure assessed by a digital health technology tool is fit-for-purpose in clinical research, care, and decision-making. Reliability assessment contributes to characterization of the signal-to-noise ratio and measurement error and is the first indicator of potential usefulness of the proposed clinical measure. Summary Methodologies for reliability analyses are scattered across literature on validation of PROs, wet biomarkers, etc., yet are equally useful for digital clinical measures. We review a general modeling framework and statistical metrics typically used for reliability assessments as part of the clinical validation. We also present methods for the assessment of agreement and measurement error, alongside modified approaches for categorical measures. We illustrate the discussed techniques using physical activity data from a wearable device with an accelerometer sensor collected in clinical trial participants. Key Messages This paper provides statisticians and data scientists, involved in development and validation of novel digital clinical measures, an overview of the statistical methodologies and analytical tools for reliability assessment.

Race/ethnic differences in the prevalence of osteoporosis, falls and fractures: a cross-sectional analysis of the Canadian Longitudinal Study on Aging. Osteoporos Int 2022; 33:2637-2648. [PMID: 36044061 DOI: 10.1007/s00198-022-06539-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Accepted: 08/22/2022] [Indexed: 10/14/2022]
Abstract
UNLABELLED Most of the published epidemiology on osteoporosis is derived from White populations; still many countries have increasing ethno-culturally diverse populations, leading to gaps in the development of population-specific effective fracture prevention strategies. We describe differences in prevalent fracture and bone mineral density patterns in Canadians of different racial/ethnic backgrounds. INTRODUCTION We described prevalent fracture and bone mineral density (BMD) patterns in Canadians by their racial/ethnic backgrounds. METHODS For this cross-sectional analysis, we used the Canadian Longitudinal Study on Aging baseline data (2011-2015) of 22,091 randomly selected participants of Black, East Asian, South or Southeast Asian (SSEA) and White race/ethnic backgrounds, aged 45-85 years with available information on the presence or absence of self-reported prevalent low trauma fractures and femoral neck BMD (FNBMD) measurement. Logistic and linear regression models examined associations of race/ethnic background with fracture and FNBMD, respectively. Covariates included sex, age, height, body mass index (BMI), grip strength and physical performance score. RESULTS We identified 11,166 women and 10,925 men. Self-reported race/ethnic backgrounds were: 139 Black, 205 East Asian, 269 SSEA and 21,478 White. White participants were older (mean 62.5 years) than the other groups (60.5 years) and had a higher BMI (28.0 kg/m2) than both Asian groups, but lower than the Black group. The population-weighted prevalence of falls was 10.0%, and that of low trauma fracture was 12.0% ranging from 3.3% (Black) to 12.3% (White), with Black and SSEA Canadians having lower adjusted odds ratios (aOR) of low trauma fractures than White Canadians (Black, aOR = 0.3 [95% confidence interval: 0.1-0.7]; SSEA, aOR = 0.5 [0.3-0.8]). The mean (SD) FNBMD varied between groups: Black, 0.907 g/cm2 (0.154); East Asian, 0.748 g/cm2 (0.119); SSEA, 0.769 g/cm2 (0.134); and White, 0.773 g/cm2 (0.128). Adjusted linear regressions suggested that Black and both Asian groups had higher FNBMD compared to White. CONCLUSION Our results support the importance of characterizing bone health predictors in Canadians of different race/ethnic backgrounds to tailor the development of population-specific fracture prevention strategies.

Abstract
Background Although the health benefits of physical activity are well documented, most older adults are not sufficiently active. There is a need to explore approaches to physical activity promotion amongst older adults that meet the personal preferences and needs of participants, and that can be implemented on a large scale in community-based settings. The current study evaluates Daily Moves, a community-based physical activity program for older adults living in Adelaide, Australia. Methods The Daily Moves program, which ran almost entirely during the COVID-19 pandemic, provided participants with personalized plans and information about suitable physical activity promoting activities available in their local area. This study used an explanatory sequential mixed-methods approach to evaluate associations between participation in the Daily Moves program and physical activity engagement, physical function and psychosocial wellbeing, and to explore the experiences of Daily Moves participants through qualitative interviews, with a particular focus on the impact of the COVID-19 pandemic on program participation and enjoyment. Results The research evaluation included 69 older adults (mean age at baseline = 73.9 ± 5.6 years; 19 male). Following Daily Moves, participants reported an increase in self-report physical activity levels (mean increase = 1.8 days, p < 0.001), improvements on several measures of physical function (left grip strength (mean increase = 1.8 kg, p < 0.001); right grip strength (mean increase = 1.3 kg, p = 0.03); Timed Up and Go (mean decrease = 1.3 s, p < 0.001)), and no significant changes in measures of psychosocial wellbeing. Qualitative interviews revealed that participants valued the supportive and flexible nature of Daily Moves, and that they felt connected with staff and other participants despite the onset of the pandemic. Conclusions This evaluation demonstrates that physical activity programs embedded within the community can provide flexible and tailored recommendations to participants, and that this approach can promote positive change in important indicators of health in older adults.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:12145. [PMID: 36231451 PMCID: PMC9564782 DOI: 10.3390/ijerph191912145] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 09/18/2022] [Accepted: 09/22/2022] [Indexed: 06/16/2023]
Abstract
Sarcopenia is one of the most important health problems in advanced age. In 2019, the European Working Group of Sarcopenia in Older People (EWGSOP) updated the operational diagnostic criteria for identification of people with sarcopenia (EWGSOP2). Among the two proposed low performance measures of sarcopenia are gait speed and the Timed Up and Go (TUG) test. Usage of any of those tools requires recalculation for the second one for eventual comparisons. The simple linear regression has been used for such comparisons in several previous studies, but the appropriateness of such an approach has not been verified. The aim of this study is to find the most appropriate model describing the relationship between these two popular measures of physical function. The study was performed in 450 consecutive outpatients of the Geriatric Clinic of the Medical University of Lodz, Poland, aged 70 to 92 years who volunteered to participate in the study. The TUG test and gait speed at 4 m to assess physical function were used. Different alternative models were compared to obtain the highest R-squared values. A Reciprocal-Y model (R-squared = 71.9%) showed the highest performance, followed by a Logarithmic-Y square root-X model (R-squared = 69.3%) and a Reciprocal-Y square root-X model (R-squared = 69.1%). The R-squared for the linear model was 49.5%. For the selected reciprocal model, the correlation coefficient was 0.85 and the equation of the fitted model was: Gait speed (m/s) = 1/(-0.0160767 + 0.101386 × TUG). In conclusion, in independent community-dwelling older adults, the relationship between gait speed and the TUG test in older subjects is nonlinear. The proposed reciprocal model may be useful for recalculations of gait speed or TUG in future studies.
