A erobic exercise training in stroke has been shown to increase lower extremity strength, 1 improve aerobic capacity, 2 and functional abilities.3 Although these outcomes may impact health-related quality of life (HRQL), 4 the effect of aerobic exercise on HRQL has been much less investigated. Improvement in HRQL after combined aerobic and strengthening exercise has been reported, 5 whereas others have shown no effect. 6 Aerobic training alone was investigated in only 1 study with no effect.
7Previous studies used mainly treadmill and cycle ergometers, with none examining more accessible and less expensive modes of aerobic training such as overground walking. The purpose of this study was to determine the effect of a community-based, 12-week aerobic (walking) exercise program on functional status and HRQL in community-dwelling stroke survivors.
Methods
Design and SubjectsA single-blind randomized controlled trial was done. The study received ethics approval, and subjects gave written informed consent. Subjects were recruited from among those treated at 3 hospitals in the parishes of Kingston and St. Andrew. Persons included were: ≥40 years of age, community dwelling, 6 to 24 months after stroke, able to walk with or without an assistive device, not currently in a rehabilitation or regular exercise program, not having any disorder that would compromise exercise training, such as unstable cardiovascular diseases, and not having any cognitive deficits.
ProceduresPotential candidates were screened for eligibility by a medical practitioner before baseline assessment, then block randomized to intervention and control groups. Reassessment was done at 6 weeks and 3 months (end of training). Participants were assessed by a physical therapist blinded to group assignment.
InterventionSubjects were supervised by trained instructors to walk briskly along a prescribed course for 15 minutes, 3 times per week, for 12 weeks, initially, progressing by 5 minutes per week up to 30 minutes in their home or community. Target heart rate was 60% to 85% of agepredicted maximum heart rate (220-age). Training progression was also carried out by increasing speed.Background and Purpose-Little is known about the effects of community-based walking programs in persons with chronic stroke. The purpose of this study was to determine the effects of aerobic (walking) training on functional status and health-related quality of life in stroke survivors. Methods-A single-blind randomized controlled trial was conducted. The intervention group (n=64)
