Hip and knee angle while walking
Hip and knee angle in degrees through a 20 point movement cycle for 39 boys
An array of dim c(20, 39, 2) giving the "Hip Angle" and "Knee Angle" for 39 repetitions of a 20 point gait cycle.
The components of dimnames(gait) are as follows:
[[1]] standardized gait time = seq(from=0.025, to=0.975, by=0.05)
[[2]] subject ID = "boy1", "boy2", ..., "boy39"
[[3]] gait variable = "Hip Angle" or "Knee Angle"
