Motor Learning for Upper Limb Hemiparesis After Stroke

Motor Learning for Individuals With Upper Limb Hemiparesis After Stroke

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.

Study Overview

• Status: Completed
• Conditions: Stroke; Hemiparesis
• Intervention / Treatment: Behavioral: Practice Variable; Behavioral: No Practice Variable

Detailed Description

Stroke involves loss of blood flow to the brain and can cause impaired upper limb motor function, resulting in long term disability. Targeted motor learning interventions can improve skill acquisition and functional upper limb use after stroke. For example, repetitive practice of a motor task has been shown to improve motor learning outcomes. However, more research is currently needed to identify important active ingredients in complex motor learning interventions and determine the most effective approaches for improving upper limb recovery after stroke. The purpose of this study is to investigate the impact of a specific practice variable on motor learning for individuals with upper limb hemiparesis after stroke. This research will inform the development of future stroke rehabilitation interventions aimed at improving skill acquisition and motor learning.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Training with Practice Variable; 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.	Behavioral: Practice Variable; This group receives the practice variable. The practice variable being studied will not be disclosed until completion of testing procedures.
Other: Training without Practice Variable; 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.	Behavioral: No Practice Variable; This group does not receive the practice variable. The practice variable being studied will not be disclosed until completion of testing procedures.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
24-Hour Retention Test: Number of completed scoops (more affected arm)	This is a 24-hour Retention Test of the trained motor task (the Scooping Task) that the participant practiced for 2 days. The participant is asked to use a spoon to scoop beans from one cup to another in an anterior-posterior direction, away from their body, for 30 seconds. One completed scoop occurs when at least one bean is transferred to the second cup. The score is the number of completed scoops that occur within 30 seconds. The participant will complete two blocks of five trials (30 seconds each). The number of completed scoops will be averaged across blocks of trials.	Day 3

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Immediate Transfer Test: Number of transported cubes (more affected arm)	This is an Immediate Transfer Test that will be administered on Day 2 following completion of training on the Scooping Task. The participant is asked to transport cubes in an anterior-posterior direction away from their body, using the Box and Block Test apparatus, for 30 seconds. The score is the number of cubes that are transported within 30 seconds. The participant will complete two blocks of five trials (30 seconds each). The number of transported cubes will be averaged across blocks of trials.	Day 2
24-Hour Transfer Test: Number of transported cubes (more affected arm)	This is a 24-Hour Transfer Test that will be administered on Day 3. The participant is asked to transport cubes in an anterior-posterior direction away from their body, using the Box and Block Test apparatus, for 30 seconds.
