Characterization of Muscle Activity During a Surface EMG-controlled Rehabilitation Game

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.

Inclusion Criteria for children with cerebral palsy: * Participants with cerebral palsy who are able to walk, GMFCS stages I through III, hemiplegic, diplegic, or quadriplegic * Aged 7 to 17 years * With palpable contractions of the target muscles (triceps surae and tibialis anterior) (≥ 1 on the Medical Research Council \[MRC\] scale) * Having received verbal and written information about the protocol, having agreed to participate in this study, and having signed a consent form if the participant is 15 years of age or older * Signed consent for participation from the participant's legal guardians * Enrolled, either personally or through their parents, in a social security program Inclusion Criteria for adults with hemiparesis * Stroke in the subacute or chronic phase * Aged 18 to 85 years * With palpable contractions of the target muscles (triceps surae and tibialis anterior) (≥ 1 on the Medical Research Council \[MRC\] scale) * Having received verbal and written information about the protocol and having signed a consent form to participate in this study * Enrolled in a social security program Inclusion Criteria for Healthy subjects matched for age to the group of participants with hemiparesis * Aged 18 to 85 * No neurological disorders * Who received verbal and written information about the protocol and signed a consent form to participate in this study. Exclusion Criteria: * Surgery on the lower extremities within the past 6 months * A botulinum toxin injection into the triceps surae and/or the tibialis anterior within the past 3 months * Pain during dorsiflexion or plantarflexion of the ankle joint * Cognitive impairments limiting participation * A person referred to in Articles L1121-5, L1121-6, L2121-8, L1121-9 of the Public Health Code * Participating in another therapeutic or drug intervention study that could affect this study
