Motor Task Practice for Hemiparesis
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how different practice conditions might help stroke survivors improve the use of their weaker arm. Participants will split into two groups to practice a simple motor task, such as scooping beans with a spoon, over two days. One group will experience a special practice element revealed later. The trial aims to determine which practice method better supports learning and retaining new skills. It is suitable for those who had a stroke over six months ago, have arm weakness, and can follow simple instructions. As an unphased study, this trial offers participants the chance to contribute to innovative research that could enhance rehabilitation techniques for stroke survivors.
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 prior data suggests that this protocol is safe for stroke survivors?
Research shows that specific safety information for using motor task practice to help stroke survivors improve arm use is lacking. This means clear evidence about its safety in humans is unavailable. However, motor task practice, a type of rehabilitation exercise, is generally well-tolerated by patients.
Similar studies involving task-oriented training have observed improvements in motor control and daily activities, suggesting these exercises usually don't cause harm. While this doesn't provide direct safety evidence, it indicates that similar therapies are generally safe. Participants in these studies often report positive results without significant negative effects.12345Why are researchers excited about this trial?
Researchers are excited about the Motor Task Practice for Hemiparesis trial because it explores how different practice strategies might enhance rehabilitation for individuals with hemiparesis, a condition often resulting from a stroke that causes weakness on one side of the body. Unlike traditional therapies that might focus on repetitive exercises without variation, this trial investigates the impact of incorporating a specific practice variable into motor training. The goal is to uncover whether varying practice conditions can lead to more effective motor learning and faster recovery times. By comparing training with and without this practice variable, the trial could reveal new insights into optimizing rehabilitation exercises, potentially leading to more personalized and effective treatment plans for patients.
What evidence suggests that this trial's treatments could be effective for hemiparesis?
Research has shown that varying practice routines can significantly enhance motor skill learning. One study found that people who practiced in diverse ways retained task performance better, even after a break. Additionally, repeated practice of specific tasks has helped stroke survivors improve movement control, facilitating everyday activities. In this trial, participants will be divided into two groups: one will train with a practice variable, while the other will train without it. Adding variety to practice sessions may lead to better recovery for those with hemiparesis, a condition where one side of the body is weaker or less coordinated. These findings support the idea that varying practice conditions could aid stroke survivors in regaining arm function.25678

Are You a Good Fit for This Trial?
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

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.

Experimental Treatment
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.
