1. A computer implemented system for assessing the mobility of a subject, said system comprising:
- a camera to record motion of said subject;
a motion sensor to receive an output from said camera and determine movement of said subject, said motion sensor generating a data stream representative of such movement;
a database;
a first computer implemented assessment engine including a computer generated prompt to prompt an operator to provide data related to a test being performed by said subject,an input to permit an operator to provide additional data in response to said prompt for recordal with said data stream in a database;
said system further including a second computer implemented assessment engine including a comparator to permit a comparison between motion represented by said data stream and representative movements recorded in said database to indicate whether said output is within said known norm, an allocator operable upon an indication of said comparator to allocate said motion to either a known norm or outside a known norm, and a deviation function to compare motion represented by said data stream with a representative movement and to detect abnormalities in such motion, and;
an output to indicate to an operator a classification of the mobility of said subject.

Abstract
A mobility assessment detects abnormalities in motion using a stagger algorithm. The detected abnormalities are compared to known norms for a particular test to determine if the abnormalities are normal or not. The comparison can be made for abnormalities associated with different diseases and illnesses to classify whether or not the condition exists and its phase. The results may be used to generate a treatment regime.

9. A method of assessing mobility of a subject using a computer implemented system having a camera to record motion of said subject;
- a motion sensor;
a database;
a first computer implemented assessment engine and a second computer implemented assessment engine, said method comprising the steps of;recording motion of said subject with said camera, utilising said motion detector to determine movement of said subject from an output from said camera, utilising said first assessment engine to prompt an operator to provide data related to a test being performed by said subject, recording an input provided by said operator in response to said prompt with said data stream in said database; utilising said second computer implemented assessment engine to; perform a comparison between motion represented by said data stream and representative movements recorded in said database, determining whether said comparison is within a known norm, allocating said motion according to whether or not it is within a known norm, applying a deviation function to compare motion represented by said data stream with a representative movement and to detect abnormalities in such motion, and; providing an output to indicate to an operator a classification of the mobility of said subject. - View Dependent Claims (10, 11, 12, 13)
