Reduced Physical Fitness in Patients With Heart Failure as a Possible Risk Factor for Impaired Driving Performance / Michael L. Alosco in American Journal of Occupational Therapy, Vol. 69/2 (Mars/Avril 2015)
[article]
Titre : Reduced Physical Fitness in Patients With Heart Failure as a Possible Risk Factor for Impaired Driving Performance Type de document : texte imprimé Auteurs : Michael L. Alosco, Auteur ; Marc S. Penn, Auteur ; Mary Beth Spitznagel, Auteur Année de publication : 2015 Article en page(s) : p.1-8 Langues : Français (fre) Mots-clés : Insuffisance cardiaque Conduite automobile Trouble cognitif léger Facteur risqueAutomobile driving Cognition disorders Computer simulation Heart failure Physical fitness Risk factors Résumé : OBJECTIVE. Reduced physical fitness secondary to heart failure (HF) may contribute to poor driving; reduced physical fitness is a known correlate of cognitive impairment and has been associated with decreased independence in driving. No study has examined the associations among physical fitness, cognition, and driving performance in people with HF.
METHOD. Eighteen people with HF completed a physical fitness assessment, a cognitive test battery, and a validated driving simulator scenario.
RESULTS. Partial correlations showed that poorer physical fitness was correlated with more collisions and stop signs missed and lower scores on a composite score of attention, executive function, and psychomotor speed. Cognitive dysfunction predicted reduced driving simulation performance.
CONCLUSION. Reduced physical fitness in participants with HF was associated with worse simulated driving, possibly because of cognitive dysfunction. Larger studies using on-road testing are needed to confirm our findings and identify clinical interventions to maximize safe driving.Permalink : ./index.php?lvl=notice_display&id=35871

Titre : Cardiorespiratory demand and rate of perceived exertion during overground walking with a robotic exoskeleton in long-term manual wheelchair users with chronic spinal cord injury: A cross-sectional study Type de document : texte imprimé Auteurs : Manuel J. Escalona ; Rachel Brosseau ; Martin Vermette ; Alain Steve Comtois ; Cyril Duclos ; Mylène Aubertin-Leheudre ; Dany H. Gagnon Année de publication : 2018 Article en page(s) : p. 215-223 Note générale : Doi : 10.1016/j.rehab.2017.12.008 Langues : Anglais (eng) Mots-clés : Spinal cord injuries Exercise Rehabilitation Technology Physical fitness Oxygen consumption Résumé : Background
Many wheelchair users adopt a sedentary lifestyle, which results in progressive physical deconditioning with increased risk of musculoskeletal, cardiovascular and endocrine/metabolic morbidity and mortality. Engaging in a walking program with an overground robotic exoskeleton may be an effective strategy for mitigating these potential negative health consequences and optimizing fitness in this population. However, additional research is warranted to inform the development of adapted physical activity programs incorporating this technology.
Objectives
To determine cardiorespiratory demands during sitting, standing and overground walking with a robotic exoskeleton and to verify whether such overground walking results in at least moderate-intensity physical exercise.
Methods
We enrolled 13 long-term wheelchair users with complete motor spinal cord injury in a walking program with an overground robotic exoskeleton. Cardiorespiratory measures and rate of perceived exertion (RPE) were recorded by using a portable gas analyzer system during sitting, standing and four 10m walking tasks with the robotic exoskeleton. Each participant also performed an arm crank ergometer test to determine maximal cardiorespiratory ability (i.e., peak heart rate and O2 uptake [HRpeak, VO2peak]).
Results
Cardiorespiratory measures increased by a range of 9%–35% from sitting to standing and further increased by 22%–52% from standing to walking with the robotic exoskeleton. During walking, median oxygen cost (O2Walking), relative HR (%HRpeak), relative O2 consumption (%VO2peak) and respiratory exchange ratio (RER) reached 0.29mL/kg/m, 82.9%, 41.8% and 0.9, respectively, whereas median RPE reached 3.2/10. O2Walking was moderately influenced by total number of sessions and steps taken with the robotic exoskeleton since the start of the walking program.
Conclusion
Overground walking with the robotic exoskeleton over a short distance allowed wheelchair users to achieve a moderate-intensity level of exercise. Hence, an overground locomotor training program with a robotic exoskeleton may have cardiorespiratory health benefits in the population studied.Permalink : ./index.php?lvl=notice_display&id=80593
