Characterization of Muscle Activity During a Surface EMG-controlled Rehabilitation Game (CONTRACTIV-1S)

17 settembre 2026 aggiornato da: Rennes University Hospital

The aim of this pilot study is to evaluate muscular activity during a single session of surface electromyography controlled exergame (muscle activation, number of contraction…) in cerebral palsy kids, hemiparetic adults and healthy controls.

Secondary aims are to assess different game mode (one-player, coactive two-player or competitive two-player and different gameplay (a rhythm and a platform gameplay) on muscle activation, number of contraction and on participant's experiences. Another aim is to assess enjoyment, motivation, flow and usability in hemiparetics adults.

Descrizione dettagliata

During the game session, participants will be paired in advance of the visit (an adult participant with hemiparesis paired with another adult participant with hemiparesis, or a healthy volunteer and a child with cerebral palsy paired with another child with a cerebral palsy) to allow for testing of different conditions for the electromyography-controlled rehabilitation game. The estimated duration for each participant is 1 hour and 30 minutes, including a 30-minute game session.

Participants will play the rehabilitation game under different modalities : individually, in pairs in a co-active mode, or in a competitive mode.

In individual mode, they play two different games a rythm game (following the musical tempo by alternating agonist/antagonist contractions) and a target game (the participant controls a rocket that must hit targets based on the intensity of muscle contractions and the muscle being activated....).

The game modalities will be presented in a randomized order.

Sperimentale: Surface EMG-controlled Rehabilitation Game

Exergame

During the game session, participants will be paired in advance of the visit (an adult participant with hemiparesis paired with another adult participant with hemiparesis, or a healthy volunteer and a child with cerebral palsy paired with another child with a cerebral palsy) to allow for testing of different conditions for the electromyography-controlled rehabilitation game. The estimated duration for each participant is 1 hour and 30 minutes, including a 30-minute game session.

Participants will play the rehabilitation game under different modalities : individually, in pairs in a co-active mode, or in a competitive mode.

In individual mode, they play two different games a rythm game (following the musical tempo by alternating agonist/antagonist contractions) and a target game (the participant controls a rocket that must hit targets based on the intensity of muscle contractions and the muscle being activated....).

The game modalities will be presented in a randomized order.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Muscle activation level
Lasso di tempo: Day 1 : during the rhythm game in the individual mode

calculated as the mean of the maximum values of the normalized RMS envelope of the EMG signal during each muscle contraction of the Tibialis Anterior and Lateral Gastrocnemius muscles

Day 1 : during the rhythm game in the individual mode

Misure di risultato secondarie

Day 1 : between game mode

Lasso di tempo: Day 1 : between game mode

The co-contraction index between the tibialis anterior and lateral gastrocnemius muscles will be calculated as the ratio between the area of overlap under the activation curves and the total area corresponding to the activation of both muscles, expressed as a percentage :

I = (area of overlap under the curve / total area of the two muscles) × 100.
