About this trial

People who had a stroke at least 6 months prior and who still have difficulty with walking will each be randomly assigned to receive either moderate or vigorous intensity walking exercise. Both protocols will be performed individually with a physical therapist for 45 minutes, 3x/week for 12 weeks. Measures including walking function will be assessed at baseline (PRE), after 4, 8 and 12 weeks of training (12WK) and at 3-month follow up (3moPOST), by raters who are unaware of the participant randomization.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age 30-85 years at time of consenting

Hemiparesis from ischemic and/or hemorrhagic strokes

Most recent stroke for which participant sought treatment, at least 6 months prior to study consent

Walking speed <1.0 m/s on the 10-meter walk test

Disqualifiers

Exercise testing uninterpretable for ischemia or arrhythmia (e.g. resting ECG abnormality that makes exercise ECG uninterpretable for ischemia and no other clinical testing from the past year available to rule out these conditions)

Evidence of significant arrhythmia or myocardial ischemia on treadmill ECG graded exercise test in the absence of recent (past year) more definitive clinical testing (e.g. stress nuclear imaging) with negative result

Hospitalization for cardiac or pulmonary disease within past 3 months

Implanted pacemaker or defibrillator with an upper heart rate limit that would interfere with exercise testing or prescription, or with unknown limit

Trial design

Design model

Parallel

Treatments tested in this trial

  • Moderate-Intensity Aerobic Training

    Behavioral

    Overground and treadmill walking with speed continuously adjusted to maintain a target heart rate of 40 +/- 5% heart rate reserve, progressing up to 55 +/- 5% heart rate reserve.

  • High-Intensity Interval Training

    Behavioral

    Overground and treadmill walking with 30 second bursts at maximum speed alternated with 30-60 second passive recovery periods. Intended to achieve a target average heart rate above 60% heart rate reserve.

Time frame
Change from Baseline to 12 weeks

Secondary outcomes

1

6-Minute Walk Test Distance

Total distance walked in 6 minutes in meters

Time frame
Change from Baseline to 3 month follow up
2

Self-Selected Gait Speed

From 10-meter walk test at self-selected speed, in meters per second

Time frame
Change from Baseline to 12 weeks
3

Fastest Gait Speed

From 10-meter walk test at fastest speed, in meters per second

Time frame
Change from Baseline to 12 weeks
4

PROMIS-Fatigue Scale version 8a

An 8-item self-report questionnaire about symptoms of fatigue. Each item is rated from 1-5. Items are combined to obtain a total T score, where higher scores indicate greater fatigue.

Time frame
Change from Baseline to 3 month follow up
