About this trial

The goal of this clinical trial is to compare two rehabilitation methods to improve finger movements in people who have had a stroke. The main question it aims to answer is which of these two training methods leads to the most improvement:

1. Teaching people to reach their movement goals using any strategies they like. 2. Teaching people to improve their movement technique and avoid compensatory strategies.

There is no one-size-fits-all approach. The second goal is to find out who might benefit more from each method. Some people with stroke may rely on compensatory strategies due to severe impairment, while others with milder strokes might benefit more from techniques that enhance movement quality.

The third goal is to take pictures of the brain to see how it changes with each method. This will help researchers understand how the brain adapts after a stroke and could lead to treatments that target the brain directly.

Participants will:

1. Visit the lab for clinical and research assessments on weeks 1, 4, 5, and 15. 2. Complete 10 days of piano training. 3. Undergo magnetic resonance imaging (MRI) scans twice, once in week 1 and once in week 4.

This trial does not accept healthy volunteers

Qualifiers

Over 18 years of age

Treatments tested in this trial

  • Quality Training

    Behavioral

    Participants will engage in piano playing tasks using their affected hand and fingers. The training focuses on specific aspects of finger movement, and participants will receive feedback related to their playing. They will wear a wrist brace for support, and their hand and arm positions will be monitored to ensure proper technique.

  • Goal Training

    Behavioral

    Participants will engage in piano playing tasks using their affected hand and fingers. The training emphasizes learning to play and producing music. Feedback will be provided on various aspects of performance such as speed and accuracy, but specific details about finger movement or technique will not be given. The use of a wrist brace and monitoring of hand and arm positions will be consistent with standard practice.

Trial outcomes

Primary outcomes

1

Finger Individuation: Force

The Finger Individuation - Force is a measure of how well a finger is able to exert force without the other fingers exerting force. This measure has been used to study finger movements in healthy individuals, pianists, and stroke survivors. This task will use a custom device to measure finger movements in all digits of both hands. The forearm will be placed on a table with the wrist in a neutral position and secured to prevent other movements. The device will support the palm and measure the force each finger produces using sensors under each fingertip. The investigators will determine participants' maximum finger force. Then, participants will practice producing forces at 20%, 40%, 60%, and 80% of this maximum for each finger while keeping the others still. They will see a visual target for the required force and get feedback on their performance.

Time frame
Pre-training (baseline), Post-training-1 (day 3), Post-training-2 (day 7), and Follow-up (3 months)
2

Finger Individuation: Joint Angular Excursion

The Finger Individuation - Joint Angular Excursion is a measure of how well a finger is able to bend or straighten while the other fingers remain stationary. The angle being measured in this task is the degree of flexion and extension at the finger joints. Specifically, it tracks the movement at the metacarpophalangeal (MCP) joint (i.e., the joint where the finger meets the hand), and proximal interphalangeal (PIP) joint (i.e., joint between the first and second finger bones). Infrared markers will be placed on the metacarpal MCP and PIP joints to track finger movement using two 3-camera Optotrak Certus motion capture systems.

Time frame
Pre-training (baseline), Post-training-1 (day 3), Post-training-2 (day 7), and Follow-up (3 months).

Secondary outcomes

1

Fugl Meyer Upper Limb assessment (FM-UL)

The FM-UL assessment assesses the sensorimotor impairment in individuals who have had stroke. It assesses movements, coordination, and reflexes.

Time frame
Pre-training (baseline), Post-training-1 (day 3), Post-training-2 (day 7), and Follow-up (3 months).
2

Action Research Arm Test (ARAT)

The ARAT is a 19-item assessment designed to evaluate upper extremity motor activity. It measures how well individuals can perform specific arm and hand tasks, focusing on four main areas: grasp, grip, pinch, and gross movement.

Time frame
Pre-training (baseline), Post-training-1 (day 3), Post-training-2 (day 7), and Follow-up (3 months).
3

Nine-Hole Peg Test (9-HPT)

The 9-HPT is a standardized, quantitative assessment designed to evaluate finger dexterity. In this test, participants are required to pick up pegs from a container one at a time and place them into holes on a pegboard as quickly as possible.

Time frame
Pre-training (baseline), Post-training-1 (day 3), Post-training-2 (day 7), and Follow-up (3 months).
4

MRI: Neural activation and connectivity in ipsilesional and contralesional motor cortex

The investigators will examine how various areas of the brain function and interact, with a focus on the regions that control movement. They will specifically assess both the injured side of the brain (ipsilesional) and the uninjured side (contralesional) to observe how each responds during tasks.

Time frame
Baseline and Post-training-1 (day 3)
