Range of motion


The opposite of equal amounts of distance between
two or more points, or not equally distanced.

Figures of merit to be minimized or maximized.

Of or relating to or in terms of parameters, or
factors that define a system.

Joint and segment markers used during motion
capture that reflect visible or infrared light.

Consists of the two hip bones, the sacrum, and the
coccyx. It is located between the proximal spine
and the hip joints.

Motion of the long axis of the pelvis within the
sagittal plane as seen by an observer positioned
along the medial-lateral axis of the laboratory.

Motion of the medial-lateral axis of the pelvis
within the coronal plane as seen by an observer
positioned along the anterior-posterior axis of the
laboratory.

Motion of the medial-lateral or anterior-posterior
axis of the pelvis within the transverse plane as seen
by an observer positioned along the longitudinal
axis of the laboratory.

The position of the pelvis as defined by a marker set
(for example, plane formed by the markers on the
right and left anterior superior iliac spine (ASIS)
and a marker between the 5th lumbar vertebrae and
the sacrum) relative to a laboratory coordinate
system.

Movement of the foot away from the anterior part
of the tibia in the sagittal plane.

The back or behind, also referred to as dorsal.

Toward the point of attachment or origin.

Indicates joint motion excursion from the maximum
angle to the minimum angle.
