About this study

Official title: Associations Between Contextual Interference, Engagement During Treatment, and Change in Motor Performance Among Patients Posts-stroke

The aim of the study is to examine associations between contextual interference (CI), engagement during practice and changes in upper limb motor performance among patients post-stroke.

Fifty patients over the age of 18, after a stroke, in the sub-acute and early chronic stages who have weakness of the upper extremity and are treated in a rehabilitation center will be recruited.

The study will include participation in five sessions: session 1 for baseline assessment, session 2-4 for practice of upper extremity functions, and session 5 for post intervention assessment. The intervention will include training of three items from the Wolf motor function test in random order (high CI group) or block order (low CI group). Outcomes of engagement will include the brain engagement index, heart rate variability and galvanic skin response. Outcomes of learning will include the pre-post change in performance of the wolf motor function selected items.

The aim of the study is to examine associations between contextual interference (CI), engagement during practice, and changes in upper limb motor performance among patients post-stroke.

Fifty patients over the age of 18, after a stroke, in the sub-acute and early chronic stages who are treated in a rehabilitation center inpatient or outpatient clinics, who have hemiparesis (Fugl-Meyer score = 11-60) will be recruited.

Patients with a history of neurological diseases other than stroke or orthopedics conditions that impair upper extremity function, pain that prevents active movement, hemodynamic instability, cognitive decline and language difficulties that do not allow understanding of instructions and cooperation will be excluded.

The study will include participation in five sessions. In the first session, participants will answer a demographic questionnaire and a set of motor (including the Wolf motor function test), perception and cognitive tests will be delivered. Then participants will be assigned to either high or low CI groups. In the next three sessions, participants will practice three items from the Wolf motor functions test. Participants in the high CI group will practice the items in random order and those in the low CI group will practice the selected items in blocked order. Assessment of outcomes during practice will include assessment of brain engagement index by recording EEG (one electrode) and heart rate variability and galvanic skin response. In the fifth session, at the end of the intervention, a reassessment of the wolf motor function performance will be performed.

What is being measured

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

  1. Change in Brain Engagement Index

    EEG activity in the prefrontal cortex will be measured by MindWave mobile EEG headset.

    Measured: Practice session 1 (1-2 days following pre-intervention session), practice session 2 (1-2 days following practice session1), and practice session 3 (1-2 days following practice session1)

  2. Change in time to complete each of three items of the Wolf Motor Function Test (WMFT)

    A maximum of 120 seconds is allowed. Any performance that exceeds 120 seconds is assigned 120 seconds.

    Measured: Pre-intervention session (first session), post-intervention session (session 5, 5-7 days following the pre-intervention session))

Secondary outcomes (2)
  1. Changes in Heart rate variability

    Photoplethysmograph sensor will be placed on the ring finger. Data will be used to extract R-R beat interval, and variability will be measured.

    Measured: Practice session 1 (1-2 days following pre-intervention session), practice session 2 (1-2 days following practice session1), and practice session 3 (1-2 days following practice session1)

  2. Changes in Galvanic Skin Response (GSR)

    GSR electrodes will be placed on the index and middle fingers, and the signal is reported in micro-Siemens (μS) units.

    Measured: Practice session 1 (1-2 days following pre-intervention session), practice session 2 (1-2 days following practice session1), and practice session 3 (1-2 days following practice session1)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Task-specific practice of upper extremity functions in people with Hemiparesis;Poststroke/CVA, run by University of Haifa at 1 site in Israel.

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 4 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: status not confirmed, as of the sponsor's last update on 25 Apr 2022. 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 Israel. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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

Contact Michal Kafri, PhD (972586862261, kafri.michal@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Brain Engagement Index (time frame: Practice session 1 (1-2 days following pre-intervention session), practice session 2 (1-2 days following practice session1), and practice session 3 (1-2 days following practice session1)). The study lists 2 primary outcomes in all. 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 25 Apr 2022.
