Abstract: A system, method and footwear sensor unit a footwear sensor unit removably attachable to footwear, the footwear sensor unit including: an Inertial Measurement Unit (IMU) including a 3-axis accelerometer and a 3-axis gyroscope, the IMU adapted to gather sensor data of detected movements of the footwear; and a storage device in electronic communication with the IMU, the storage device for storing the sensor data; and a communications module in electronic communication with the storage device, the communication module configured to transmit data to an external computing device.

Abstract: A computerized method performed by a processor, an apparatus and a computer program product the method comprising: receiving a model associating motion parameters of an action performed by a subject with a score, the model based at least partially on data obtained in a controlled environment while performing a task on a first time period; determining action parameters during motion of the subject within an uncontrolled environment on a second time period; and providing the action parameters to the model, to obtain an assessment of an expected score for the subject performance of the task as would be performed by the subject in the controlled environment.

Abstract: A computerized method performed by a processor, and computer program product the method comprising: receiving sensory data of motion by a human subject, the sensory data obtained during motion in an uncontrolled environment; extracting features from the sensory data; identifying a plurality of strides from the features extracted from the sensory data; calculating kinematic parameters of each stride from the plurality of strides from the sensory data; classifying each stride from the plurality of strides in accordance with the kinematic parameters to obtain a stride type; and outputting the stride type for the plurality of strides.
