Lecture 4 Biomechanical Principles: Kinematic Measurements Flashcards
1
Q
Ways to objectively measure human movement
A
- electrogoniometry
- accelerometry
- imaging techniques
2
Q
What are kinematics?
A
Branch of mechanics that describe motion without consideration of forces or Torques that are going to produce that motion
3
Q
Electrogoniometer
A
measures joint angular rotation during movement
- Pro: inexpensive and direct
- Con: cumbersome to patient
4
Q
Accelerometer
A
measures acceleration of either individual segment or whole body
- segment: multiples accelerometers would be needed for 3D or multi-segment analysis (cumbersome and can limit normal ROM)
- whole body: used to estimate PA (ex: fitbit)
5
Q
Image techniques include
A
photography and videography
6
Q
Kinematic Measurement Systems
A
- mechanical devices
- transducers
- electromechanical devices
7
Q
Mechanical devices
A
scale, grip strength dynamometer & hand-held dynamomter
8
Q
Transducers
A
Force place
-measures ground reaction forces
9
Q
Electromechanical devices
A
Isokinetic dynamometer (Biodex)
