OPErA Orchestral Posture Egonomic Assessment

Demographic, medical history, and musical activity data will be collected using a specifically designed questionnaire

"Questionnaire that evaluate pain and functional limitation during last week, last six months e during the carrier.~The impact of painful symptoms on professional and non-professional activities , during the last week, will be assessed using the QuickDASH scale for the upper limb, the Modified Oswestry Low Back Disability Index for low back pain, and the Neck Disability Index questionnaire for cervico-dorsalgia"

Postural assessment without the instrument in a sitting position. Disposable ECG electrodes will be applied to the following anatomical landmarks: Spinous process C7 (C7), Right shoulder acromion (RS), Left shoulder acromion (LS), Right scapula inferior angle (RIA), Left scapula inferior angle (LIA), Spinous process L3 (L3), Intergluteal line (IG), vertex. The Physical Analyzer Portable will be used: a non-invasive, portable device that allows calibrated photo acquisition on the frontal and sagittal planes and subsequent data processing through dedicated software. On frontal plane they will be calculated: Trunk inclination, Head-neck inclination, Right and left shoulder height, Right and left shoulder width, right and left scapula-rachis distance. On sagittal plane they will be calculated: cervical and lumbar arrow, right and left shoulder distance.
