About this study

The primary goal of this project is to establish whether fMRI measurements of brain connectivity measured before and after interaction with a sensorimotor task can predict subsequent training-induced gains in motor function in a population of individuals with chronic stroke.

This study involves individuals with chronic motor impairment resulting from stroke. The procedures include one fMRI session (baseline), followed by twelve training visits (2 or 3 times per week over 4-5 weeks) focused on training motor function of the hand and wrist conducted with a physical therapist. During imaging, participants interact with an MRI-compatible joystick that will cue participants to move their wrist in a controlled way. Before and after the training program, subjects will undergo behavioral testing with a physical therapist to quantify changes in clinical measures of impairment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Conventional Physical Therapy InterventionBehavioural

    The training sessions will consist of high repetitions of finger flexion/extension and grip/object manipulation tasks, wrist flexion/extension and radial/ulnar deviation and forearm supination/pronation tasks performed while seated, standing or lying comfortably. All activities are typical of those conducted in physical therapy post-stroke except for the high number of repetitions. Some example tasks might include using a mallet to hammer pegs into a hole, pouring water from one cup into another, or spinning a pencil with the fingertips. Difficulty of tasks will be scaled to the capability level of each individual so that at least 200 repetitions of each exercise can be completed with 50-85% accuracy and a patient-reported difficulty of 5-9 out of 10.

What is being measured

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

  1. Goodness of fit (R^2) of a model predicting change in Upper Extremity Fugl-Meyer score from pre-post task changes in resting-state functional connectivity

    The primary outcome is the goodness of fit (R^2) of a regression model relating brain connectivity measures (predictors) to gains in motor function after stroke (clinical measurement).

    Predictors: resting-state functional connectivity measured using resting-state fMRI (rs-fMRI). Connectivity is quantified as Fisher-transformed correlation coefficients (z scores, unitless) of signal measured in pairs of regions (edges) within the cortico-thalamic-cerebellar network. Predictors include baseline (pre-task) connectivity and connectivity changes calculated as the difference between post-task and pre-task rs-fMRI measurements.

    Clinical measurement: change in Upper Extremity Fugl-Meyer Assessment (FM-UE) score (units: points), calculated as post-intervention FM-UE minus pre-intervention FM-UE.

    Outcome: model goodness of fit (R^2, unitless). We use a custom LASSO-based variable selection method to construct the final model given multiple predictors and quantify the model fit via R^2.

    Measured: Brain connectivity is measured during the MRI visit conducted at Baseline. rsFMRI scans are collected within 10 minutes before and after a motor task. FM-UE is assessed once at Baseline and once at the end of the five week enrollment period.

Secondary outcomes (1)
  1. Goodness of fit (R^2) of a model predicting change in Upper Extremity Fugl-Meyer score from corticospinal tract injury

    The secondary outcome is the goodness of fit (R^2) of a linear regression model relating corticospinal tract injury (predictor) to gains in motor function after stroke (clinical measurement).

    Predictor: percent corticospinal tract injury (%CST injury) quantified using a structural MRI brain scan (FLAIR). The FLAIR image shows the location and volume of lesioned tissue, and %CST injury is quantified as the percentage of CST axon bundles (derived from a previously published healthy template) that overlap with the lesion (predictor units: percent damaged axon bundles).

    Clinical measurement: change in Upper Extremity Fugl-Meyer Assessment (FM-UE) score (units: points), calculated as post-intervention FM-UE minus pre-intervention FM-UE.

    Outcome: model goodness of fit (R^2, unitless). We use linear regression to relate %CST injury to the change in FM-UE and quantify the model's fit via R^2.

    Measured: Structural brain scan (FLAIR) is acquired once during the MRI visit at Baseline. FM-UE is assessed once at Baseline and once at the end of the five week enrollment period.

Questions about this trial

What is this clinical trial studying?

A study testing Conventional Physical Therapy Intervention in people with Stroke, run by University of Delaware at 2 sites 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 5 inclusion and 8 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 24 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

Goodness of fit (R^2) of a model predicting change in Upper Extremity Fugl-Meyer score from pre-post task changes in resting-state functional connectivity (time frame: Brain connectivity is measured during the MRI visit conducted at Baseline. rsFMRI scans are collected within 10 minutes before and after a motor task. FM-UE is assessed once at Baseline and once at the end of the five week enrollment period.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 24 Jun 2026.
