Improving Hand Motor Function After Stroke: Role of Robotics

April 26, 2018 updated by: Rocco Salvatore Calabrò, IRCCS Centro Neurolesi "Bonino-Pulejo"
Two recent randomized clinical trials reported a significant contribute of Amadeo toward the recovery of hand motor function in acute stroke patients in association with physiotherapy and/or occupational therapy. However, no data are available in patients with chronic stroke, and the neurophysiological mechanisms underlying such clinical improvement need to be elucidated. Given that robotic devices harness brain plasticity to foster motor function recovery, a deeper understanding of the neurophysiological bases of Amadeo training could help clinician to realize patient-tailored rehabilitative training based brain plasticity knowledge. We planned a pilot randomized-controlled observer trial aimed at evaluating the effects of intensive robot-assisted hand therapy compared with intensive occupational therapy in chronic phase after stroke. We estimated that 40 patients per group will be required to demonstrate a greater effect of Amadeo as compared to occupational therapy, with an effect size of 0.5. Twenty chronic stroke patients (at their first-ever stroke) will be enrolled and randomized into two groups. The experimental group will be provided with Amadeo training. The Control group will be provided with occupational therapy executed by a trained physiotherapist.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • chronic stroke patients at their first-ever supratentorial stroke

Exclusion Criteria:

  • presence of severe medical, psychiatric and cognitive abnormalities as to interfere with the treatment.
  • controindications to the device use.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Amadeo training
All participants will receive 40 sessions of treatment (45-minute) for 8 consecutive weeks (5 days/week). The robotic exercises will be carried in passive modality (15 minutes), passive/plus (15 minutes), assisted modality (15 minutes).
Device: Amadeo Training

To understand the cortical modifications related to movement preparation and execution after robot-assisted training we will study the EEG modifications of cortical activity using time-frequency event-related EEG and task-related coherence (TRCoh).

Friedman ANOVA with post-hoc t-test (corrected for multiple comparisons) will be used to assess the significance of training-induced changes in the two groups.
Active Comparator: occupational therapy
All participants will receive 40 sessions of treatment (45-minute) for 8 consecutive weeks (5 days/week). The control group will receive the same amount of training by physiotherapist skilled in occupational tharapy.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Nine hole peg test
Time Frame: by 5 minutes
Administered by asking the client to take the pegs from a container, one by one, and place them into the holes on the board, as quickly as possible. Participants must then remove the pegs from the holes, one by one, and replace them back into the container. The board should be placed at the client's midline, with the container holding the pegs oriented towards the hand being tested. Only the hand being evaluated should perform the test. Hand not being evaluated is permitted to hold the edge of the board in order to provide stability. Scores are based on the time taken to complete the test activity, recorded in seconds. Alternative scoring - the number of pegs placed in 50 or 100 seconds can be recorded. In this case, results are expressed as the number of pegs placed per second. Stopwatch should be started from the moment the participant touches the first peg until the moment the last peg hits the container.
by 5 minutes

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
cortical modifications related to movement preparation and execution after robot-assisted training
Time Frame: about 30 minutes
Assessment of EEG modifications of cortical activity using time-frequency event-related EEG and task-related coherence (TRCoh).
