Patent ID: 7503900

Claim:
A method for quantifying asymmetry of joint angles of two limbs during a movement, comprising: determining a first set of data that comprises angles of a joint of a first limb as the first limb performs the movement; determining a second set of data that comprises angles of a joint of a second limb as the second limb performs a similar movement, wherein the two limbs comprise the first limb and the second limb; determining a plurality of data pairs, wherein each data pair includes a first angle from the first set of data and a second angle from the second set of data, and wherein the first angle occurs when the first limb performs an indentifiable event during the movement, and wherein the second angle occurs when the second limb performs the identifiable event during the movement; generating a cyclogram in two-dimensional space based on the determined plurality of data pairs by treating each data pair as a point; and determining a value of a characteristic of the generated cyclogram, wherein the value quantifies asymmetry of joint angles of the first limb and the second limb.
