Résumé : |
Objective To compare oxygen cost (mL·kg−1·m−1) and cardiovascular response (beats/m) and oxygen consumption (mL·kg−1·min−1) and heart rate (beats/min) to stair ascending and descending with walkers, with canes, and without assistive devices (ADs) in older adults. Design Descriptive, repeated measures. Setting Indoor stairway. Participants Convenience sample of able-bodied volunteers, non-AD users (N=14; mean age, 63.71+11.7y; mean body mass, 72.7+14.1kg; mean height, 165.7+9.2cm). Interventions Participants performed 4 randomized trials of stair ascending and descending at their own self-selected speed with 3 ADs: single-point cane, standard walker (SW), and wheeled walker (WW). They also performed unassisted stair ascending and descending. Each trial consisted of a 5-minute steady-state session followed by a 2-minute data collection period. Steady-state expired ventilations were collected in Douglas bags for metabolic analysis. Main Outcome Measures Oxygen cost (mL·kg−1·m−1), heart rate (HR) response (beats/m), oxygen consumption (mL·kg−1·min−1), and HR (beats/min) were compared for each trial of stair ascending and descending using analysis of variance repeated measures (P<.05> Results Greater oxygen cost (per meter) was found for stair ascending and descending using the single-point cane (121%), SW (217%), and WW (232%) compared with unassisted stair ascending and descending (P<.05 increased hr response meter was found for stair ascending and descending using the single-point cane sw ww compared with unassisted however oxygen consumption minute were not significantly during ads descending. participants ascended descended at reduced speeds trials ads.> Conclusions This research should aid clinicians by providing evidence to base recommendations on regarding AD usage when encountering stairs during home and community ambulation. |
