Objective To compare cardiorespiratory responses between pool floor walking and overground walking (OW) in people poststroke. Design Cross-sectional study. Setting University-based therapeutic exercise facility. Participants Participants (N=28) were comprised of 14 community-dwelling individuals poststroke (5.57+3.57y poststroke) and 14 age- and sex-matched healthy adults (mean age, 58.00+15.51y; male/female ratio, 9:5). Interventions Not applicable. Main Outcome Measures A telemetric metabolic system was used to collect cardiorespiratory variables, including oxygen consumption ( o2), energy expenditure (EE), and expired volume per unit time ( e), during 6-minute walking sessions in chest-depth water and on land at a matched speed, determined by average of maximum walking speed in water. Results Individuals poststroke elicited no significant differences in cardiorespiratory responses between pool floor walking and OW. However, healthy controls showed significant increases in mean o2 values by 94%, EE values by 109%, and e values by 94% (all P<.05 during pool floor walking compared with ow. a mixed model analysis of variance revealed significant group condition interaction in o2 which the control increased> o2 from OW to pool floor walking, whereas the stroke group did not. Conclusions Our results indicate that people poststroke, unlike healthy adults, do not increase EE while walking in water compared with on land. Unlike stationary walking on an aquatic treadmill, forward locomotion during pool floor walking at faster speeds may have increased drag force, which requires greater EE from healthy adults. Without demanding excessive EE, walking in water may offer a naturally supportive environment for gait training in the early stages of rehabilitation. |
