Description détaillée
L'accident vasculaire cérébral (AVC) est la principale cause d'incapacité grave à long terme, touchant 9,4 millions d'Américains. Chaque année, environ 800 000 personnes subissent un AVC, même aux États-Unis. L'atteinte motrice chronique du membre supérieur est un facteur majeur contribuant à l'incapacité ; l'utilisation fonctionnelle du membre supérieur affecté dans la vie quotidienne est un facteur clé pour accroître l'autonomie, le retour au travail et la qualité de vie globale. Ainsi, un traitement efficace et innovant pour lutter contre l'incapacité à long terme est à la fois un besoin majeur de santé publique et une nécessité économique.
L'étude développera une plateforme innovante d'interaction homme-machine pour cibler et améliorer la coordination inter-articulaire et la fonction motrice en renforçant la coordination musculaire dans le membre supérieur. Cette étude impliquera au total 38 survivants d'AVC chroniques qui seront répartis aléatoirement entre deux stratégies de rééducation : soit des exercices guidés par la coordination neuromusculaire (NICE ; groupe thérapie), soit des exercices guidés par la force (groupe témoin). Les critères d'inclusion sont principalement : (1) avoir subi un AVC ischémique ou hémorragique au moins 6 mois auparavant (AVC chronique) ; (2) être âgé de 21 à 80 ans ; (3) ne pas avoir reçu de traitement à la toxine botulique dans le bras affecté au cours des 3 derniers mois ; et (4) ne présenter aucune déficience cognitive susceptible d'affecter la compréhension des tâches ou la capacité à donner un consentement éclairé.
Cette étude évaluera les effets des deux types d'exercices de rééducation sur la coordination musculaire, les scores cliniques standardisés, la cinétique et l'électroencéphalogramme.

Expérimental: Neuromuscular coordination enhancement (NICE) intervention
Post-stroke participants will perform a center-out task by activating individual motor modules (generating coordinated isometric contractions of muscles) to move the cursor on a screen while electromyographic (EMG) signals are recorded.
Activation of each muscle (or muscle group) will be mapped to 1 of 4 directions within the multi-dimensional cursor space.
We will derive the cursor position in real time using Motor module activation magnitudes recorded from arm muscles.
|
Neuro-Intermuscular Coordination Enhancement (NICE) is a motor module-guided rehabilitation intervention designed to improve upper-extremity motor recovery after stroke by retraining impaired intermuscular coordination patterns. Participants perform isometric upper-extremity force-generation tasks using a human-machine interface while receiving real-time visual feedback derived from motor module recruitment signals calculated from surface electromyography (EMG). Individualized motor module targets are derived from the participant's less-affected upper extremity and used to guide selective recruitment of impaired coordination patterns in the more-affected upper extremity. Participants will complete 18 one-hour training sessions over six weeks (3 sessions/week). During training, participants perform repetitive target-matching tasks that require preferential recruitment of specific motor modules while minimizing unintended activation of non-target modules. |
|
Comparateur actif: EMG-amplitude biofeedback exercise
Participants will perform a center-out target matching tasks where individual muscle EMGs are used to move a cursor on the visual feedback display to match one of 4 different targets presented to them.
Here, just the EMG amplitude, and not the coordination is focused on.
|
EMG Amplitude Biofeedback Exercise is an active comparator rehabilitation intervention designed to improve upper-extremity motor function after stroke through targeted muscle activation training.
Participants perform isometric upper-extremity exercises using a human-machine interface with real-time EMG amplitude-based visual feedback.
Individualized muscle activation targets derived from the less-affected upper extremity guide training of the more-affected upper extremity.
Participants will complete 18 one-hour sessions over 6 weeks (3 sessions/week).

Fugl-Meyer Assessment (FMA) score
Délai: Baseline, six- week, 10-week, and 18-week follow-ups.

Motor impairment after stroke will be measured by upper extremity FMA (UE-FMA).
The maximum UE-FMA motor score is 66 (i.e., 0: complete motor impairment; 66: normal motor performance).
Each item is scored on a 3-point scale (0 = cannot perform, 1 = performs partially, 2 = performs fully).
The FMA score reflects the level of upper extremity motor impairment.

Similarity Score of Intermuscular Coordination Patterns (or Motor Modules)
Délai: Baseline, six- week, 10-week, and 18-week follow-ups.
|
Surface EMGs will be recorded from 8 key arm muscles during a 54-target isometric force generation task.
A dimensionality reduction method (non-negative matrix factorization (NNMF)) will be applied to identify intermuscular coordination patterns - operational definition of motor modules in the field of motor neuroscience.
They are mathematically 8-dimensional unit vectors.
Similarity score is the scalar product (or dot product) between a pair of intermuscular coordination patterns in comparison (i.e., motor modules).
We compute the similarity score between the less-affected and the more-affected arms.
Also, surface EMGs will be recorded from 8 key arm muscles during 3D dynamic reaching tasks.
NNMF will be applied to EMGs to identify and compare intermuscular coordination patterns.
Similarity score is the scalar product between motor modules (i.e., intermuscular coordination patters) of the more-affected arm in stroke group and dominant arm in healthy group.
