Trial summary

Constraint-induced movement therapy (CI therapy) is a highly efficacious treatment for residual motor disability in chronic stroke. Its effectiveness is believed to be due, at least in part, to the therapy's ability to aid the brain in "rewiring itself." For example, CI therapy produces increases in the amount of grey… Read more about this study

About this study

Official title: Examining Mechanisms of Neuroplasticity Following Motor Rehabilitation in Stroke

Constraint-induced movement therapy (CI therapy) is a highly efficacious treatment for residual motor disability in chronic stroke. Its effectiveness is believed to be due, at least in part, to the therapy's ability to aid the brain in "rewiring itself." For example, CI therapy produces increases in the amount of grey matter (the parts of the brain where neuron cell bodies are most closely clustered) in certain areas of the human brain (Gauthier et al., 2008). The cellular and molecular mechanisms that are responsible for this increase in grey matter volume are not known, however. Thus, it is unclear how the therapy helps brains "rewire" themselves. This study aims to better understand the timecourse and cellular/molecular nature of brain changes during CI therapy. Because there is currently no way to directly measure cellular/molecular changes in the brain noninvasively, this study will infer what is happening on a microstructural level using new MRI techniques (three dimensional pictures of the brain). For example, by charting the timecourse of grey matter changes during CI therapy, and cross-comparing this to what is known about the timecourses of different cellular/molecular processes, the investigators can gain a greater understanding of what cellular processes may be responsible for increases in grey matter. The investigators will gain additional information about which cellular processes are important for rehabilitation-induced improvement by measuring larger-scale changes (e.g., amount of blood flow through different brain areas) that accompany cellular changes. The investigators are hopeful that by better understanding how CI therapy can change the brain, the effectiveness of rehabilitation can be improved upon. For example, insight into the mechanisms of rehabilitation-induced brain change may suggest particular drug targets to increase brain plasticity. This study will help us better understand how the brain repairs itself after injury.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Brain structure

    Assessed via dynamic susceptibility contrast MRI, diffusion tensor MRI, MRI-based myelin mapping, T1-weighted MRI

    Measured: Participants will be followed for 4-6 weeks. Change in brain structure at mid-treatment (after 1 week of CI therapy), post-treatment (after 2 weeks of therapy), and at 2-week follow-up will be measured.

Secondary outcomes (1)
  1. Motor function

    Assessed via Wolf Motor Function Test, Action Research Arm Test, Motor Activity Log

    Measured: Participants will be followed for 4-6 weeks. Change in motor function at mid-treatment (after 1 week of CI therapy), post-treatment (after 2 weeks of therapy), and at 2-week follow-up will be measured.

Questions about this trial

What is this clinical trial studying?

A study testing CI therapy in people with Stroke and Hemiparesis, run by Ohio State University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Brain structure (time frame: Participants will be followed for 4-6 weeks. Change in brain structure at mid-treatment (after 1 week of CI therapy), post-treatment (after 2 weeks of therapy), and at 2-week follow-up will be measured.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01725919, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Aug 2025; AzTrials last refreshed its copy on 8 Nov 2026.
