Systems and methods for detecting a motor developmental delay or neurodevelopmental disorder in an infant

A system for detecting a neurodevelopmental disorder of an infant, comprising:

• a sensor configured for placement at the infant's lower limb;
• and
• a computing device operably coupled to the sensor, the computing device comprising a processor and a memory operably coupled to the processor, the memory having computer-executable instructions stored thereon that, when executed by the processor, cause the computing device to:
• receive, from the sensor, motion data associated with the infant's gross motor activity;
• analyze, using a machine learning algorithm, the motion data to detect a kinematic feature;
• compare the kinematic feature to an expected relationship between the kinematic feature and infant age;
• and
• detect the neurodevelopmental disorder based on the comparison.
