Intensive cycling exercise for stroke recovery

The I-Score (Intensive Stroke Cycling for Optimal Recovery and Economic Value) Trial

Not applicable Interventional The Cleveland Clinic · NCT06585943

This study is testing whether using a special cycling machine can help stroke survivors recover better during their outpatient rehab compared to regular therapy.

What this trial studies

This clinical trial investigates the effects of forced aerobic exercise (FE) on motor recovery in stroke survivors during outpatient rehabilitation. It aims to compare the effectiveness and cost-effectiveness of FE, which involves mechanically assisted cycling, against traditional rehabilitation methods. The study will assess both the neural and biochemical mechanisms behind the recovery facilitated by FE, as well as its potential to improve outcomes for a significant portion of stroke survivors who currently experience residual disabilities. By rigorously testing this approach, the trial seeks to advance clinical practices in stroke rehabilitation.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 18-85 who are 3-9 months post-stroke with specific motor function scores indicating residual hemiparesis.

Not a fit: Patients with recent cardiac issues, multiple strokes, or those currently undergoing other therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly enhance motor recovery for stroke survivors while reducing rehabilitation costs.

How similar studies have performed: Previous studies have shown promising results with forced aerobic exercise in animal models, but this approach is relatively novel in human stroke rehabilitation.

Eligibility criteria

Show full inclusion / exclusion criteria
Sixty-six individuals with chronic stroke able to provide informed consent who meet the following criteria for inclusion will be recruited from the Cleveland Clinic:

1. 3-9 months following single ischemic or hemorrhagic stroke confirmed with neuroimaging (ie: first-time stroke)
2. Fugl-Meyer motor score 19-55 in the involved UE
3. Fugl-Meyer score \<34 in the involved LE demonstrating residual hemiparesis
4. Ambulatory ≥ 20 meters with no more than contact guard assistance
5. 18-85 years of age

Exclusion criteria include:

1. hospitalization for myocardial infarction, heart failure or heart surgery within 3 months
2. cardiac arrhythmia
3. hypertrophic cardiomyopathy
4. history of multiple strokes
5. actively undergoing physical or occupational therapy or enrolled in another interventional study
6. severe aortic stenosis
7. untreated deep vein thrombosis or pulmonary embolus
8. unstable angina
9. uncontrolled hypertension
10. implanted pacemaker or defibrillator
11. dyspnea at rest
12. clinically significant neurologic condition/diagnosis other than stroke
13. recent history of elicit drug or alcohol misuse or significant mental health illness
14. significant contractures
15. anti-spasticity injection within 3 months of enrollment
16. skull hardware (e.g. screws/plates) or prior craniotomies that could shunt current flow altering EEG measures
17. other contraindication to exercise or EEGs
