The physiological assessment in non-operative treatment on chest wall deformities, are still unclear today. These functional benefits outweigh the aesthetic benefits associated with anatomical improvement. The functional benefits, ventilation, hemodynamic and neurologic, have never been evaluated. Assessment of Effects on parasympathetic activity of the autonomic nervous system, global health criterion measured by noninvasive methods. Anatomic evaluation, between the initial and final assessment by objective measures 1) of the chest wall by MRI, and 2) of the heart by echocardiography. Noninvasive physiological assessment at rest and during exercise in respiratory function exploration flows and volumes, cardiac function by flow measurement, and overall metabolic function test effort (VO2max). Subjective assessment of functional gain between the initial and final balance sheet, based on EVA scales, valued by patients, parents and doctors.

RECRUITINGHigh frequency normalized index (HFnu)
It is a reflect of the RR short term heart rate variability (HRV) in the frequency domain. It is measured with a ECG Holter monitor
Time frame: One month after the end of treatment
Low frequency (LF and LFnu)
It is another index of RR heart rate variability (HRV) measured with a ECG Holter monitor.
Time frame: One month after the end of treatment
LF/HF ratio
It is another index of RR heart rate variability (HRV) measured with a ECG holter monitor.
Time frame: One month after the end of treatment
Blood pressure - Baroreflex
Measure of autonomic function (parasympathetic activity) - quantified via changes in blood pressure
Time frame: One month after the end of treatment
Lung residual volume
It is expressed in litres and is measured with a plethysmograph during a pulmonary function testing.
Time frame: One month after the end of treatment
Maximum flow
It is expressed in litres per minute and is measured during a pulmonary function testing. The patient is seated and his/her nose is blocked with a clamp. He/She must blow as fast and as hard as possible.
Time frame: One month after the end of treatment
Aerobic maximum power
It is measured by a stress test (incremental exercise)
Time frame: One month after the end of treatment
Maximum heart rate
It is measured by a stress test (incremental exercise)
Time frame: One month after the end of treatment
Left ventricular ejection fraction
It is measured by an echocardiography
Time frame: One month after the end of treatment
Severity index of the anatomical damage
It is measured by a thoracic MRI. It is the ratio between the thoracic width and the distance sternum/spine.
Time frame: One month after the end of treatment
Nuss Questionnaire
It is a depression scale
Time frame: One month after the end of treatment
