Study Summary

This trial will compare the effects of two different types of exercise on walking ability and cardiovascular fitness in stroke patients. HIIT is hypothesized to result in greater benefit than MICE.

You have had a stroke more than 10 weeks ago and have difficulty moving your leg or foot, or have a certain type of abnormal walking pattern due to the stroke.
You do not have a severe language impairment that may affect communication, as noted in clinical reports or referral form.
You do not have any bone or joint problems that may get worse due to the study.
You need to fully understand and agree to participate in the study before you can take part.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: High Intensity TrainingExperimental Treatment1 Intervention
High Intensity Interval Training patients will attend the centre 3 times/week for 24 weeks. All subjects will participate in MICE aerobic training 5 days/week in the first four weeks of the study to provide a foundation of fitness and endurance for the safe prescription of HIIT. Subsequently, the HIIT group will replace 3 MICE training days with 3 HIIT. HIIT sessions will include two 20 minute protocols; 30:60 second work:active rest ratio, and 120:180 second work:active rest ratio on a treadmill with a harness for fall protection. In addition to supervised exercise training (3 times/week), MICE will be conducted 2 times/week in the home/community, which has been shown to be both safe and effective
Group II: Moderate Intensity ExerciseActive Control1 Intervention
Moderate Intensity Continuous Exercise patients will attend the centre 3 times/week for 24 weeks. Participants will be progressed to 30 to 60 minutes of continuous exercise at the heart rate that occurred at the anaerobic threshold on the exercise test. Participants will exercise on a treadmill with a harness ofr fall protection. In addition to supervised exercise training (3 times/week), MICE will be conducted 2 times/week in the home/community by both cohorts.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

How many participants are accepted into this research experiment?

"Affirmative. The details posted on clinicaltrials.gov indicate that this medical trial is actively recruiting participants. It was first published in March of 2017 and modified most recently on January 14th 2020, with the need for 104 patients from a single site being specified."

Answered by AI

Are there any vacancies for participation in this experiment?

"Affirmative, the material on clinicaltrials.gov reveals that this medical experiment is actively searching for participants. It was initially posted on March 1st 2017 and amended most recently on January 14th 2020 with a need to enlist 104 patients at one single site."

Answered by AI

What are the core goals of this clinical examination?

"The primary aim of this trial, to be measured after 0 and 24 weeks, is the alteration in cardiovascular fitness as calculated by peak oxygen uptake (VO2peak). Secondary objectives entail a determination of patients' ability to reach intensity thresholds during HIT training and MICE using an ambulatory oxygen monitor; ventilatory values assessed with CORTEX Biophysik MetaMax®3X portable gas analysis every 10 seconds; changes over time via two executive function measures for selective attention and inhibition processes alongside speed-of-processing tests such as Trails A/B, DKEFS verbal fluency assessments, and Weschsler digit symbol coding."
