Objective To assess the effects of guidance force (GF) and gait speed (GS) on cardiorespiratory responses and energy cost in subacute dependent ambulatory patients with stroke. Design Cross-sectional study. Setting University rehabilitation hospital. Participants Patients with subacute stroke (N=10; mean age, 64.50+19.20y) who were dependent ambulators (functional ambulation category ≤2). Interventions Patients participated in cardiorespiratory tests during robot-assisted gait training. Subjects walked at a fixed percentage (50%) of body weight support and various percentages of GF (100%, 80%, and 60%) and GS (1.4 and 1.8km/h). The therapist encouraged patients to maximize their locomotor ability. Main Outcome Measures During the cardiorespiratory tests, oxygen consumption (View the MathML sourceV˙o2), heart rate, and respiratory exchange ratio were measured continuously to assess cardiometabolic demands. Results There were no significant differences in cardiometabolic demands according to GS (1.4 vs 1.8km/h). There were no significant differences in cardiometabolic demands according to GF at a GS of 1.4km/h. However, lowering GF decreased View the MathML sourceV˙o2 when comparing GFs of 100% (6.89+2.38mL/kg/min), 80% (6.46+1.73mL/kg/min), and 60% (5.77+1.71mL/kg/min) at a GS of 1.8km/h (P=.03). Conclusions Lowering the GF of robot-assisted gait training at a higher GS cannot induce a sufficient cardiometabolic demand for subacute dependent ambulatory patients with stroke. This implies that it is important to take the patient's functional ability into consideration when choosing training protocols. |
