Orthotics Lecture Part 2 From Guest Speaker

Question 1

What is the goal of any orthotic treatment

Answer 1

1. Limit or assist motion
2. Limit deformity or pain
3. Protect fragile structures — prevent further progression or reduce stress on a joint

Question 2

Where is the center of gravity for the human body

Answer 2

About a 2 inch square box around S2.
Want gait to be seamless and fluid to decrease abnormalities
Abnormalities = inefficiency = more energy expended.

Question 3

What are the determinants of gait that help minimize vertical/horizontal displacement of the center of gravity

Answer 3

1. Pelvic rotation
2. Pelvic tilt
3. Knee flexion at midstance
4. Foot and ankle motion
5. Knee motion
6. Lateral pelvic displacement
   *all fluency energy expenditure and the mechanical efficiency of walking.
