The standard assessment of movement disorders is reliant on subjective, visual analysis. Clinicians use scorecards like AIMS (Tardive Dyskinesia) and UPDRS (Parkinson's) to qualitatively evaluate movement abnormalities. Recently, technology such as wearable IR sensors and accelerometers have been used to capture more quantitative, objective data. Unfortunately, these techniques require clinician and lab time -- both of which are expensive and time-consuming. Using 3D cameras and face-tracking, GAGE provides a cheap, accessible system for objectively automating existing motion and gait disorder tests, all from the comfort of the patient’s home.

Imagine if you couldn't walk normally or get up from a chair, or if parts of your body moved when you didn't want them to. If you have a movement disorder, you experience these kinds of impaired movement. Dyskinesia is a common symptom of many movement disorders. Dyskinesia results in broken or jerky motions. Tremors are a type of dyskinesia. Hyperkinetic disorders are characterized by abnormal involuntary movement. These excess movements can be regular and rhythmic, as in tremor; more sustained and patterned, as in dystonia; brief and random, as in chorea; or jerk-like and temporarily suppressible, as in tics. Diagnosis of the specific condition depends primarily upon careful observation of the clinical features.
