The following graphs show gaits of a 21-year old man who is claiming
workers compensation for his left knee injury.
The first graph shows his left (blue) and right (red) gait curves extracted from a 200-meter walk test conducted in a doctor's office.
A severe abnormality in his left leg is shown clearly, with all gait phases dimished.
The second graph is a segment extracted from his 24-hr test at home, which shows near normal gaits.
Comparing the above tests, we conclude his inconsistency in gaits and bring the veracity of his claim into question.
