A motion analysis tool without body sensors developed for the objective assessment of movement in children with SMA

To overcome the shortcomings of functional scales in children such as CHOP-INTEND, German researchers have developed and tested a method for capturing and analyzing movement in ten children with SMA (eight with type I and two type II), aged 2 to 46 months. 

• the commercial device used (KineMAT) allows to record the child’s movements objectively in three dimensions of space but without having to place sensors on the child’s body. 
• the correlation with the CHOP-INTEND figures obtained in parallel is quite acceptable.
