Finding Representative Curves Using Principle Components
Recently it was discovered that differences in movement patterns exist among subjects that suffer from chronic ankle instability (CAI). To learn about differences, a study was conducted in that subjects were asked to perform a jump-cut maneuver. During the maneuver angles associated with the knee, ankle, and hip were measured from two planar perspectives over time. This resulted in six curves measured on each individual. Having one representative movement curve for each plane would facilitate interpretation and as a result would be very appealing to practitioners. We show how this can be carried out using functional principle components and curve registration.
