HES 301 Exam 2 Questions and Answers
with Verified Solutions | Latest Updated 2026
Motion the process of changing position
Motion Analysis science of comparing sequential skill
images
captured from photographing a body in
motion
What does motion analysis - angular / linear displacement
calculate? - distance
- joint position
- ROM
- velocity
- speed
- acceleration
Two-dimensional motion analysis: reference objects captured in view and
calibration converted
into pixels (qualitative analyses, limited
quantitative
analyses) (x and y axis)
Three-dimensional motion reference static or dynamic objects of
analysis: known
calibration dimension with multiple markers (high
speed
cinematography) (x, y, and z axis)
, Reflective markers - positioned in center anatomical landmark
- correspond to an (x, y, and z) coordinate
per
frame
Digitization conversion of parts of numerical position
data
(frame-by-frame)
Manual Digitization cursor is moved, clicked, and marked
Automatic Digitization reflective markers are automatically
defined
Digitization calculation: An image 500 points/sec
captures at 50 Hz using 10
markers
would generate how much data?
Linear Motion (translation) all points on body or object move same
distance,
in the same direction, and at the same
time
Rectilinear "linear motion"
Curvilinear "curved pathway"
