study description: Infantile spinal muscular atrophy is a common disease (the second most common fatal autosomal recessive disease after cystic fibrosis), neurodegenerative disorders of childhood causing severe motor impairment and a risk to life through respiratory failure in the most severe forms.

Innovative therapies (gene therapy or pharmacogenetics) have recently proven their effectiveness on survival criteria. Nevertheless, the motor benefit of these therapies must be evaluated more precisely.

Currently, the reference methods for motor development assessment are fairly robust semi-quantitative motor scales that lack sensitivity and do not reflect function (CHOPINTEND, HINE, BAYLEY SCALE, MFM and CGI-scale).

Advances in recent techniques have enabled the emergence of non-invasive, secure, easy-to-use inertial sensors in routine clinical practice that allow quantification of infant movements.

The aim of the study is to propose a method for quantifying motor function in infants with spinal muscular atrophy treated with innovative therapies using inertial sensors.
