Objective : To examine the peak oxygen consumption [VO2peak] and heart rate [HRpeak] performing 30 structured and progressive
task-oriented exercises [SPTOE] for walking training in individuals post-stroke and compare the intensity among three steps of
exercise.
Materials and Methods : Subjects with ambulatory (cid:976)irst stroke who registered at the Faculty of Physical Therapy, Mahidol University
were invited to participate. Each exercise was sequentially (cid:976)ive minutes for performance and (cid:976)ive minutes for resting in between.
Subject performed 10 tasks per step a day and continued step I, II, and III of exercise. The VO2peak and HRpeak were measured using the
Oxycon Mobile portable and polar heart rate monitoring. Data were used to estimate the metabolic equivalent of tasks [METs] and
percentage of heart rate reserve [%HRR]. The Friedman’s ANOVA and Wilcoxson signed-rank tests were used for statistical analysis.
Results : Of 134 patients registered at the Physical Therapy Clinic, 10 subjects participated (39 to 70 years of age and 30 to 570
days post-stroke). The authors (cid:976)indings demonstrated signi(cid:976)icant differences of VO2peak, METs, HR, and %HRR among the three
steps of SPTOE (p<0.001). Three steps were serially arranged according to the VO2peak (5.5 to 8.4 ml·kg-1·min-1 for step I, 6.4 to 10.1
ml·kg-1·min-1 for step II and 7.7 to 12.1 ml·kg-1·min-1 for step III).
Conclusion : Regarding to the American Stroke Associations for exercise recommendations, low-to-moderate intensity of 30
task-oriented exercises can be used for walking training in individuals with post-stroke.
