Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment No Practice Variable, Practice Variable for hemiparesis?

Research shows that repetitive task-specific practice, especially when combined with electrical stimulation and behavioral supports, can significantly reduce impairment in stroke survivors with moderate upper extremity deficits. This suggests that practice-based treatments may be effective for improving motor function in individuals with hemiparesis.12345

Is motor task practice for hemiparesis safe for humans?

The studies reviewed do not provide specific safety data for motor task practice in humans, but they do not report any adverse effects, suggesting it may be generally safe.56789

How does the treatment 'Motor Task Practice for Hemiparesis' differ from other treatments for hemiparesis?

This treatment is unique because it focuses on task-specific motor learning, which can stimulate neuroplastic changes in the brain, helping to reorganize and improve motor function after a stroke. Unlike general arm use, task-specific practice has been shown to facilitate motor learning and alter brain activity patterns, potentially leading to better recovery outcomes.29101112

What is the purpose of this trial?

The purpose of this research is to learn about practice conditions that may benefit stroke survivors when learning to use their more affected arm to perform a task. Participants will be randomized into two groups. Experimental and control groups will differ by one practice variable that will not be disclosed until completion of testing procedures. Participants will practice a motor task using both their more and less affected arms for two consecutive days. A Pre-Test will be administered on Day 1 before the training begins. Immediate Transfer of Learning will be administered on Day 2 after the completion of training. Delayed (24-hour) Retention and Transfer Tests will be administered on Day 3.

Eligibility Criteria

This trial is for stroke survivors with upper limb weakness who can follow commands and have had a stroke at least 6 months ago. They should be able to speak English, have not received Botox in the last 3 months, and not currently be in upper limb therapy. Severe neglect or arm pain that limits movement disqualifies participation.

Inclusion Criteria

It has been over 6 months since my stroke.
My Box and Block test score is between 3 and 60.
I can understand and follow simple instructions.

Treatment Details

Interventions

  • No Practice Variable
  • Practice Variable
Trial Overview The study tests how different practice conditions affect learning to use the affected arm after a stroke. Participants are divided into two groups by chance; one group will receive an undisclosed practice variable during training. The effectiveness of these methods is measured over three days.
Participant Groups
2Treatment groups
Experimental Treatment
Group I: Training without Practice VariableExperimental Treatment1 Intervention
All participants will practice a motor task (the Scooping Task) for 2 consecutive days. Each day of training, participants will complete 50 trials (10 blocks of 5 trials each) with their more affected arm and 20 trials (10 blocks of 2 trials each) with their less affected arm. One trial of the task will involve using a spoon to scoop beans, one at a time, from one cup to another while seated at a table. Participants will be asked to complete as many scoops as possible from the cup closest to them to the cup farthest from them within 30 seconds in an anterior-posterior direction. One successful repetition occurs when at least one bean is transferred. The number of successful repetitions within a 30 second trial is then counted. Training for the control group will not include the practice variable of interest.
Group II: Training with Practice VariableExperimental Treatment1 Intervention
All participants will practice a motor task (the Scooping Task) for 2 consecutive days. Each day of training, participants will complete 50 trials (10 blocks of 5 trials each) with their more affected arm and 20 trials (10 blocks of 2 trials each) with their less affected arm. One trial of the task will involve using a spoon to scoop beans, one at a time, from one cup to another while seated at a table. Participants will be asked to complete as many scoops as possible from the cup closest to them to the cup farthest from them within 30 seconds in an anterior-posterior direction. One successful repetition occurs when at least one bean is transferred. The number of successful repetitions within a 30 second trial is then counted. Training for the experimental group will include the practice variable of interest.

Findings from Research

In a study involving 9 chronic stroke survivors, a combination of repetitive task-specific practice (RTP) with electrical stimulation and behavioral supports led to significant improvements in upper extremity function and dexterity over an 8-week period.
Participants showed marked increases in their ability to use their affected arm for daily activities, indicating that this intervention not only improved physical capabilities but also enhanced their quality of life by enabling them to perform valued tasks they had previously been unable to do.
