4.3 Gait Analysis Flashcards
1
Q
Stride
A
How far the same foot is after one step movement
Right = Left generally
2
Q
Step length
A
How far one foot is in front of the other
Right = Left generally
3
Q
Step width
A
How far wide are the steps
4
Q
Cadence
A
5
Q
Walking speed
A
Stride length/Stride duration
6
Q
Gait cycle
A
60% stance- 40% swing
7
Q
Parallax error
A
Apparent displacement of object due to a change in the observer’s point of view
8
Q
Parallax optimal distance
A
8 metres

Q
Pre-requisites of gait
A
- Stability in stance (support of body weight) (Prevented by injury, loose ligaments, scoiolysis)
- Sufficient foot clearance in swing
- Appropriate swing phase pre-positioning of foot
- Adequate step-length
- Energy Conservation

Q
Systematic approach to gait analysis
A
Planes in order:
1. Sagittal
2. Coronal
3. Transverse
Body systems:
Gait features + clinical exam –> Probable impairment
