Standing balance tests can be used to diagnose and assess neurological and musculoskeletal abnormalities that affect the lower extremity and central nervous system. The IsoBALANCE (Neuromuscular Technologies) force plate system tracks postural sway in the coronal and sagittal planes and quantifies total distance travelled as well as the percentage of time a subject remains within a 0.5, 1.0, and 1.5 inch radius from his/her mean center of gravity (MCOG).
