Diaphragmatic Breathing Exercise for Patients Undergoing Arthrodesis Surgery for Adolescent Idiopathic Scoliosis.

"The standard postoperative rehabilitation process starts from the first postoperative day. Two sessions are provided daily, with the exception of Sunday and Saturday afternoon. A single physiotherapy session, lasting 30 minutes, can include bed exercises for upper and lower limbs and recovery of autonomy (sitting position, standing and ambulation). In this phase, the sessions are characterized by educational and counseling activities.~The patient will be encouraged to carry out the activities independently."

The subjects in the intervention group (EXP) will receive, in addition to standard physiotherapy treatment, diaphragmatic breathing exercise. Four exercises in different position (supine and side lying) will be provided for each physiotherapy session by a senior physiotherapist. Patients will be instructed to perform the same exercises independently to achieve relaxation and relief of pain symptoms.
