61 Calculated Moment :
62 Calculated Power:
63 Calculated Length:
64 Calculated Vector Angle:
65 Calculated Vector Angular Velocity:
66 Calculated Vector Angular Acceleration:
67 Calculated Joint Moments (3D): The moments about the three joint axes.
68 Calculated Joint Powers: The total powers in each joint.
69 Calculated Segment Reference Points:
3-D coordinates of the internal joint centres and other reference points calculated from a Gait-specific
marker set. The data is not in any defined segment order - the names must be read from Data type 50.
Names will be defined as e.g. “Left Hip”, “L.Hip”, “R.Ankle”, etc.
70 Calculated Segment Rotations:
The three relative orientation components of a segment/joint ( α, β, γ ).
α : flexion/extension/tilt(pitch) β : ab/adduction/obliquity(yaw) γ : rotation (roll)
The data is not in a defined joint/segment order: the segment/joint names must be read from Data type 50.
Segment/joint names will be defined as e.g. “Pelvis”, “Left Hip”, “L.Hip”, “Right Foot”, “R.Foot”, etc.
