Improving Hand Motor Function After Stroke: Role of Robotics

Phase N/A Results N/A

Trial Description

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.

Conditions

Interventions

  • Amadeo Training Device
    Intervention Desc: 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.
    ARM 1: Kind: Experimental
    Label: Amadeo training
    Description: 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).
    ARM 2: Kind: Experimental
    Label: occupational therapy
    Description: All participants will receive 40 sessions of treatment (45-minute) for 8 consecutive weeks (5 days/week). The control group will receive thwe same amount of training by physiotherapist skilled in occupational tharapy.

Outcomes

Type Measure Time Frame Safety Issue
Primary Nine hole peg test by 5 minutes
Secondary cortical modifications related to movement preparation and execution after robot-assisted training about 30 minutes
