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

Detaljeret beskrivelse
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.

Co-contraction intensity of the Tibialis Anterior/Lateral Gastrocnemius muscle
