2.6. Intervention
PD
All intervention classes, synchronous and asynchronous remote video-based, will be held in the Biomechanics & Ergonomics Laboratory (b) at the Department of Physical Education and Sport Science, University of Thessaly, Trikala, Greece. Their structure is focusing on refining innate musicality and coordination via rhythmic movement, hearing training and improvisation.Risk management strategy includes a qualified carer who will be present during both the synchronous and asynchronous modalities, full explanation of the experimental procedures, controlled laboratory temperatures at about 22° Celsius, as well as the continuous presence of at least two members of the research team.The protocol has a duration of 45 min of rhythmic training and includes sections of warming up, stretching, breathing, movement combinations, a dance sequence, and recovery. Each exercise is accompanied by music that provides a clear and predictable rhythm. More specifically, the beat or rhythm of the music is used as a guide for the timing and duration of specific movements, allowing people with PD to coordinate their movements with the music. Simple values will be introduced, such as whole notes, half notes, and quarter notes, clapping and tapping, breathing, and sounds. Class will be accompanied by recorded classical piano music to meet the needs of the synchronous learning format and asynchronous remote video-based format. The intensity of the class will be moderate, at approximately 3 MET. The instructor will be an experienced dance teacher in musicokinetic education. Protocol details can be found in
