ABSTRACT
Introduction: Lower-limb physical function declines with age and contributes to a greater difficulty in performing activities of daily living. Existing assessments of lower-limb function assess one dimension of movement in isolation or are not time-efficient, which discourages their use in community and clinical settings. We aimed to address these limitations by assessing the inter-rater reliability and convergent validity of a new multimodal functional lower-limb assessment (FLA). Methods: FLA consists of five major functional movement tasks (rising from a chair, walking gait, stair ascending/descending, obstacle avoidance, and descending to a chair) performed consecutively. A total of 48 community-dwelling older adults (32 female participants; age: 71 ± 6 years) completed the FLA as well as timed up-and-go, 30-s sit-to-stand, and 6-min walk tests. Results: Slower FLA time was correlated with a slower timed up-and-go test (ρ = 0.70), less sit-to-stand repetitions (ρ = -0.65), and a shorter distance in the 6-min walk test (ρ = -0.69; all, p < 0.001). Assessments by two raters were not different (12.28 ± 3.86 s versus 12.29 ± 3.83 s, p = 0.98; inter-rater reliability ρ = 0.993, p < 0.001) and were statistically equivalent (via equivalence testing). Multiple regression and relative weights analyses demonstrated that FLA times were most predicted by the timed up-and-go performance [adjusted R 2 = 0.75; p < 0.001; raw weight 0.42 (95% CI: 0.27, 0.53)]. Discussion: Our findings document the high inter-rater reliability and moderate-strong convergent validity of the FLA. These findings warrant further investigation into the predictive validity of the FLA for its use as an assessment of lower-limb physical function among community-dwelling older adults.
ABSTRACT
PURPOSE: A significant number of people will experience prolonged symptoms after COVID-19 infection that will greatly impact functional capacity and quality of life. The aim of this study was to identify trajectories of health-related quality of life (HRQOL) and their predictors among adults diagnosed with COVID-19. METHODS: This is a retrospective analysis of an ongoing prospective cohort study (BQC-19) including adults (≥18y) recruited from April 2020 to March 2022. Our primary outcome is HRQOL using the EQ-5D-5L scale. Sociodemographic, acute disease severity, vaccination status, fatigue, and functional status at onset of the disease were considered as potential predictors. The latent class mixed model was used to identify the trajectories over an 18-month period in the cohort as a whole, as well as in the inpatient and outpatient subgroups. Multivariable and univariable regressions models were undertaken to detect predictors of decline. RESULTS: 2163 participants were included. Thirteen percent of the outpatient subgroup (2 classes) and 28% in the inpatient subgroup (3 classes) experienced a more significant decline in HRQOL over time than the rest of the participants. Among all patients, age, sex, disease severity and fatigue, measured on the first assessment visit or on the first day after hospital admission (multivariable models), were identified as the most important predictors of HRQOL decline. Each unit increase in the SARC-F and CFS scores increase the likelihood of belonging to the declining trajectory (univariable models). CONCLUSION: Although to different degrees, similar factors explain the decline in HRQOL over time among the overall population, people who have been hospitalized or not. Clinical functional capacity scales could help to determine the risk of HRQOL decline.

Purpose: The purpose of this article is to describe the development of a new Web platform to optimize self-management after pulmonary rehabilitation (PR) for persons living with a chronic respiratory disease (CRD) and to present data on its usability. Method: The Web platform is informed by a theoretical framework of behaviour changes and concepts of self-management and self-efficacy. It uses breathing exercises and a logbook and is meant to be a self-management tool. Usability was tested for 8 months after PR with a group consisting of five patients with chronic obstructive pulmonary disease and one with pulmonary fibrosis. We evaluated adherence (e.g., number of exercise/weeks), quality of life, dyspnoea, and functional capacity. We measured frequency count for adherence and pre-post differences per patient for clinical outcomes. Results: Four participants' adherence was higher than 50% of completed exercises (72 exercise/weeks). Five of six participants showed maintenance of functional capacity (6-minute walk test) 8 months after PR. Four participants showed maintenance of their quality of life. Four participants showed a deterioration in dyspnoea on the Borg Scale of Perceived Exertion. Conclusions: We developed a new theory-informed Web platform to optimize self-management after PR for persons living with a CRD. The pilot Web platform appears to optimize adherence to self-management techniques and possibly stabilize people's health outcomes.
Objectif : décrire la création d'une nouvelle plateforme en ligne pour optimiser l'autogestion après la réadaptation pulmonaire (RP) des personnes vivant avec une maladie pulmonaire chronique et présenter des données sur sa facilité d'utilisation. Méthodologie : la plateforme repose sur une structure théorique de changements de comportement et de concepts d'autogestion et d'autoefficacité. Elle se veut un outil d'autogestion faisant appel à des exercices respiratoires et à un journal. Les chercheurs en ont évalué la facilité d'utilisation auprès d'un groupe de cinq patients atteints d'une maladie pulmonaire obstructive chronique et d'un patient atteint de fibrose pulmonaire pendant huit mois après la RP. Ils ont évalué l'adhésion (p. ex., nombre d'exercices par semaine), la qualité de vie, la dyspnée et la capacité fonctionnelle. Ils ont également mesuré la fréquence pour déterminer l'adhésion et la différence avant-après de chaque patient pour évaluer les résultats cliniques. Résultats : quatre participants ont présenté une adhésion supérieure à 50 % pour ce qui est des exercices complétés (72 exercices par semaine). Quatre des six participants avaient maintenu leur capacité fonctionnelle (test de marche de six minutes) huit mois après la RP, et quatre participants avaient maintenu leur qualité de vie. Cependant, quatre participants ont présenté une détérioration de leur dyspnée à l'échelle de Borg. Conclusion : les chercheurs ont créé une nouvelle plateforme reposant sur des critères théoriques pour optimiser l'autogestion après une RP chez les personnes vivant avec une maladie pulmonaire chronique. Le projet-pilote de plateforme en ligne semble optimiser l'adhésion aux techniques d'autogestion et pourrait stabiliser l'état de santé des patients.
ABSTRACT
PURPOSE: Telerehabilitation could prevent sequelae from COVID-19. We aimed to assess the feasibility of telerehabilitation; describe pulmonary and functional profiles of COVID-19 patients; and explore the effect of telerehabilitation on improving pulmonary symptoms and quality of life. METHODS: We conducted a pre-experimental, pre-post pilot study. We recruited COVID-19 patients who had returned home following hospitalization. The intervention included eight weeks of supervised physiotherapy sessions. We documented technological issues, success of recruitment strategies, and participants' attendance to supervised sessions. We measured the impact of pulmonary symptoms on quality of life and functional health. RESULTS: We scheduled 64 supervised sessions with seven participants with few technological issues. Initial scores showed that pulmonary symptoms moderately to highly impacted quality of life. At eight weeks, all patients had improved from 10 to 45 points on the EuroQol-Visual Analog Scale (EQ-VAS) instrument, indicating clinical significance. CONCLUSION: We developed and administered a telerehabilitation intervention during a global pandemic that targets key symptoms of the relevant disease.
