SYSTEMS AND METHODS TO ASSESS BALANCE

摘要

This disclosure relates to a system and method to analyze balance and stability of a patient. Test data for the patient, representing motion of a device affixed to the patient during a test interval (e.g., at a position approximating the center of mass, such as in proximity to the torso), can be received. The test data can be processed to provide processed data (or sensor-derived data) that includes at least one of acceleration data, rotational rate data and rotational position data for the test interval. A biomechanical model can be applied to the processed data to provide center of mass (COM) motion data representing movement of the COM in multiple dimensions for the patient during the test interval. An indication of balance for the patient can be determined based on the COM motion data. The indication of balance can be used to analyze the balance and stability of the patient.

主权项

1. A computer implemented method, comprising:
receiving test data for a patient that represents motion of a portable device affixed to the patient during a test interval; processing the test data to provide processed data that includes at least one of acceleration data, rotational rate data and rotational position data for the test interval; applying a biomechanical model to the processed data to provide center of mass (COM) motion data representing movement of the COM in multiple dimensions for the patient during the test interval; and determining an indication of balance for the patient based on the COM motion data.
