data = KINEMAT_DATA(sdata,data,Pelvis,Thigh,Shank,Foot,sequence,test) computes
lower-limb (ankle, knee, hip) joint kinematics
ARGUMENTS
sdata ... zoo struct representing static trial
data ... zoo struct representing dynamic trial
Pelvis ... cell array of markers (min 3) defining pelvis segment
Thigh ... cell array of markers (min 3) defining Thigh segment
Shank ... cell array of markers (min 3) defining Shank segment
Foot ... cell array of markers (min 3) defining Foot segment
sequence ... cardan sequence to follow. Default 'yxz'
test ... Compare results against PiG computations (boolean). Requires
fully processed data file. Default false
RETURNS
data ... zoo struct with lowelimb kinematics appended as
'R/L' Ankle, Knee, Hip 'Kinemat'
NOTES
- Code based on 'cardan.m' part of Reinschmidt and Van den Bogert
'kinemat' toolbox: http://isbweb.org/software/movanal/kinemat/
- For the purposes of comparison with PiG, a right side kinematics offset is
added based on PiG static trial. Otherwise, static pose is assumed to
have 0 deg in all angles
