Abstract:
For individuals with acute stroke, it is difficult to conduct an exercise test to assess peak oxygen consumption (peak V o 2 ). Therefore, the purpose of this study was to use a clinically feasible tool for assessing prestroke peak V o 2 using a nonexercise estimation equation to test whether estimated prestroke peak V o 2 was related to the functional outcome measures at discharge from the hospital in individuals after an acute stroke. We hypothesized that the estimated prestroke peak V o 2 would be significantly related to discharge Physical Performance Test (PPT), 6-minute walk test (6MWT), and lower extremity Fugl-Meyer (LEFM) assessment. Methods: Estimated prestroke peak V o 2 was calculated using a previously validated prediction equation using the following variables: body mass index, age, sex, resting heart rate, and a self-reported measure of physical activity. Outcome measures were assessed 4 days after enrollment or immediately before discharge (whichever occurred first). Results: Thirty-four participants (mean age = 56.0, SD = 12.6 years; 20 men) with acute stroke were enrolled within 48 hours of admission. For all individuals, mean estimated prestroke peak V o 2 was 27.3 (SD = 7.4) mL·kg −1 ·min −1 and had a weak, nonsignificant relationship with the PPT (r = 0.19; P = .28), 6MWT (r = 0.10; P = .56), and LEFM (r = 0.32; P = .06). However, when considering sex, women, but not men, had a significant relationship with LEFM (r = 0.73; P = .005) and moderate but nonsignificant relationship with PPT (r = 0.53; P = .06) and 6MWT (r = 0.47; P = .10). Conclusions: Within 48 hours of stroke admission, we were able to administer a nonexercise equation to estimate prestroke peak V o 2 . For the entire sample, functional measures conducted at discharge were not related to estimated prestroke peak V o 2 . However, when considering sex, the relationship between prestroke V o 2 and the functional measures was strengthened.
