Impacts of Remote Physical Exercises on Functional Status and Mobility among Community-Dwelling Pre-Disabled Seniors during the Covid-19 Lockdown.

OBJECTIVES: To assess whether remote physical exercise interventions helped maintain function in daily life, level of physical activities, basic mobility and frailty status in pre-disabled seniors during the first Covid-19 lockdown. DESIGN: This is an interventional study conducted from May 2020 to May 2021. SETTING: Community-dwelling older adults in 2 Canadian cities. PARTICIPANTS: 84 pre-disabled seniors. INTERVENTION: 12-week physical exercise programs (1 hour/ 3 times/ week) in kinesiologist-guided groups using Zoom or phone-supervised individual booklet-based home-program (n=44) vs. Control (usual life habits; n=40). MEASUREMENTS: Functional status in daily activities (OARS scale); Daily level of aerobic (TAPA-1) and strengthening/flexibility (TAPA-2) physical activities; Basic mobility abilities (SPPB: balance, lower limbs strength, walking speed; Timed Up-and-Go) and Frailty (SOF index) were assessed at baseline and at 3, 6, 9 and 12-month follow-ups. RESULTS: The participants' mean age was 78.5 ± 7.2 and 76.5 % were women. There was a group * time effect for the OARS scale (p=0.02), the TAPA-1 (p=0.06) and the TAPA-2 (p=0.007) scores. For these outcomes, scores significantly improved during the first 3 months of follow-up and then stabilised in the intervention group whereas they remained constant in the control group over time. There was an overall time effect for the SPPB (p=0.004), the 4-m walking speed (p=0.02) and for the SOF index (p=0.004), with no between-group differences. Finally, no effect was observed for the TUG. CONCLUSION: Remote home-based physical exercise interventions and monitoring during the first Covid-19 lockdown seemed to have helped maintain seniors' level of physical activities without impacting on basic mobility abilities. Further studies are needed to identify parameters of remote exercise programs that can improve daily function and mobility in this population.

Advanced practice physiotherapy care in emergency departments for patients with musculoskeletal disorders: a pragmatic cluster randomized controlled trial and cost analysis.

BACKGROUND: Advanced practice physiotherapy (APP) models of care where physiotherapists are primary contact emergency department (ED) providers are promising models of care to improve access, alleviate physicians' burden, and offer efficient centered patient care for patients with minor musculoskeletal disorders (MSKD). OBJECTIVES: To compare the effectiveness of an advanced practice physiotherapist (APPT)-led model of care with usual ED physician care for persons presenting with a minor MSKD, in terms of patient-related outcomes, health care resources utilization, and health care costs. METHODS: This trial is a multicenter stepped-wedge cluster randomized controlled trial (RCT) with a cost analysis. Six Canadian EDs (clusters) will be randomized to a treatment sequence where patients will either be managed by an ED APPT or receive usual ED physician care. Seven hundred forty-four adults with a minor MSKD will be recruited. The main outcome measure will be the Brief Pain Inventory Questionnaire. Secondary measures will include validated self-reported disability questionnaires, the EQ-5D-5L, and other health care utilization outcomes such as prescription of imaging tests and medication. Adverse events and re-visits to the ED for the same complaint will also be monitored. Health care costs will be measured from the perspective of the public health care system using time-driven activity-based costing. Outcomes will be collected at inclusion, at ED discharge, and at 4, 12, and 26 weeks following the initial ED visit. Per-protocol and intention-to-treat analyses will be performed using linear mixed models with a random effect for cluster and fixed effect for time. DISCUSSION: MSKD have a significant impact on health care systems. By providing innovative efficient pathways to access care, APP models of care could help relieve pressure in EDs while providing efficient care for adults with MSKD. TRIAL REGISTRATION: ClinicalTrials.gov NCT05545917 . Registered on September 19, 2022.

Online physical exercise intervention in older adults during lockdown: Can we improve the recipe?

BACKGROUND: Recorded and live online physical exercise (PE) interventions are known to provide health benefits. However, the effects of prioritizing the number of live or recorded sessions remain unclear. AIMS: To explore which recorded-live sessions ratio leads to the best implementation and benefits in older adults. METHODS: Forty-six community-dwelling adults (> 60y.o.) were randomized into two groups completing a 12-week online PE intervention. Each group had a different ratio of live-recorded online sessions as follows: Live-Recorded-Live sessions (LRL; n = 22) vs. Recorded-Live-Recorded sessions (RLR; n = 24). RESULTS: Drop-out rates did not reach significance (LRL:14% vs. RLR: 29%, p = 0.20), and adherence was similar (> 85%) between groups. Both groups reported similar levels of satisfaction (> 70%), enjoyment (> 75%), and perceived exertion (> 60%). Both groups increased physical health and functional capacities, with greater improvements in muscle power (LRL: LRL: + 35 ± 16.1% vs. RLR: + 7 ± 13.9%; p = 0.010) and endurance (LRL: + 34.7 ± 15.4 vs. RLR: + 27.0 ± 26.5, p < 0.001) in the LRL group. DISCUSSION: Both online PE intervention modalities were adapted to the participants' capacities and led to a high level of enjoyment and retention. The greater physical improvements observed in the LRL group are likely due to the higher presence of the instructor compared to the RLR group. Indeed, participants received likely more feedback to appropriately adjust postures and movements, increasing the quality of the exercises. CONCLUSION: When creating online PE interventions containing both recorded and live sessions, priority should be given to maximizing the number of live sessions and not the number of recorded sessions.

[Relation between grip strength of independent elders and functional decline following an emergency department visit : a pan-Canadian study]. / Capacité de prédiction de la force de préhension et de la peur de tomber des personnes âgées autonomes quant au déclin fonctionnel suite à une consultation aux urgences. Une étude pancanadienne.

OBJECTIVE: To determine whether grip strength and fear of falling are associated with functional decline at 3 or 6 months after a minor trauma assessed in the emergency department. METHOD: Prospective multicenter cohort study of patient's aged 65 years and older, independent for activities of daily living, consulting the emergency department for minor trauma. Functional status, fear of falling, and grip strength measurements were collected. Functional decline was measured at 3 and 6 months. STATISTICS: Two groups were compared : one with functional decline, the other without. A ROC curve explored the predictive power of grip strength and initial fear of falling on the occurrence of functional decline. RESULTS: Participants were 74.7 years old, 52 % men. Initial peak grip strengths were identical (p superior to 0.05). Grip strength and fear of falling were not predictive of functional decline (p = 0.55 and p = 0.53). However, fear of falling was associated with functional decline (OR: 1.141 95 % CI [1.032-1.261]; p = 0.009). CONCLUSION: In the autonomous elder with minor trauma in the emergency department, grip strength is not associated with subsequent functional decline. But fear of falling is associated with decline at 6 months.

Objectif : Déterminer si la force de préhension et la peur de tomber sont associées au déclin fonctionnel à 3 ou 6 mois d'un traumatisme mineur évalué aux urgences. Méthode : Étude prospective de cohorte multicentrique des patients de 65 ans et plus, autonomes pour les activités de la vie quotidienne, consultant aux urgences pour traumatismes mineurs. Le statut fonctionnel, la peur de tomber, et la mesure de la force de préhension ont été recueillis. Le déclin fonctionnel a été mesuré à 3 et 6 mois. Statistiques : Deux groupes sont comparés : un avec déclin fonctionnel, l'autre sans. Une courbe ROC a exploré la puissance prédictive de la force de préhension et de la peur de tomber initiale sur l'apparition du déclin fonctionnel. Résultats : Les participants avaient 74 ± 7 ans, 52 % d'hommes. Les forces de préhension maximales initiales étaient identiques (p sup�rieur a 0,05). La force de préhension et la peur de tomber ne sont pas prédictives du déclin fonctionnel (p = 0,55 et p = 0,53). Cependant, la peur de tomber est associée au déclin fonctionnel (OR: 1,141 IC95 % [1,032-1,261]; p = 0,009). Conclusion : Chez l'aîné autonome avec un traumatisme mineur aux urgences, la force de préhension n'est pas associée au déclin fonctionnel ultérieur. Mais la peur de tomber est associée à un déclin à 6 mois.

Feasibility and Acceptability of Remote Physical Exercise Programs to Prevent Mobility Loss in Pre-Disabled Older Adults during Isolation Periods Such as the COVID-19 Pandemic.

This study aimed to assess the feasibility and acceptability of remote physical exercise (PE) to prevent mobility loss among pre-disabled older adults during the COVID-19 lockdowns. Participants followed a 12-week PE remote program in Zoom© supervised groups (Web-Ex group, n=11) or phone-supervised individual booklet-based home-program (Booklet group, n=33). The total rate of adherence was 82.5% in the Web-Ex group and 85.8% in the Booklet group. The level of satisfaction was « a lot ¼ for 60% of the participants in the Web-ex group and for 37.9% of those included in the Booklet group. Respectively 10% and 31% of the participants rated the difficulty as « low ¼ in the web-ex and Booklet groups. Remote physical exercise using a web technology or booklets at home with regular and personalized follow-up during the lockdown was feasible and acceptable among pre-disabled seniors.

Feasibility, Acceptability and Effects of a Home-Based Exercise Program Using a Gerontechnology on Physical Capacities after a Minor Injury in Community-Living Older Adults: A Pilot Study.

CONTEXT: Several studies have demonstrated that physical activity can help limit decline in functional capacities of older adults. Nevertheless, many adults aged 65 and over are inactive. OBJECTIVE: To explore the feasibility, the acceptability and the effects of a home-based exercise program (HEP) using a motion capture gerontechnology in independent community-living older adults at risk of function decline. DESIGN: Interventionnal clinical trial. PARTICIPANTS: Sixteen previously independent individuals aged 65 and older recruited at the Emergency Department after being treated for a minor injury and discharged home were assigned to a home-based exercise program group (HEP=8) or to a control group (CONTR=8). Twelve participants completed the study, 6 in each group Setting: Canadian Community-dwelling in Montreal area. INTERVENTION: The HEP group engaged in a twelve-week physical activity intervention using a gerontechnology while the CONTR group continued with discharge plan from ED. MEASUREMENTS: Participants were evaluated for functional status using validated questionnaires and objective physical measures at baseline, three and six months later. Feasibility and acceptability of the HEP was assessed using data reports from the gerontechnology and from self-reported assessments. RESULTS: There was no differences between groups at baseline except for the fallrelated self-efficacy: HEP=8.33/28±1.51 vs CONTR=7/28±0 p=0.022. The HEP was found to be feasible and acceptable (adherence rate at 86% and average quality of movements at 87.5%). Significant improvement in walking speed on 4m was observed three months after baseline for HEP vs CONTR group (+0.25 vs +0.05 m/sec, p=0.025). Effects remained at follow-up. Only CONTR group resulted in a significant increase in SF-36 global score. CONCLUSION: This twelve-week HEP intervention using the Jintronix® gerontechnology is feasible, acceptable and safe for community-living older adults who sustained a minor injury. This intervention could increase walking speed, the most important predictor of adverse events in the elderly population, and that the improvement could be maintained over time.
