Question 8

Subtalar/Midtarsal (closed chain)

Answer 8

Resting Position
- Neutral
Closed Pack Position
- Full Supination

Question 9

Resting Position (Open Pack)

Answer 9

• Surrounding tissue is lax as possible
• Intracapsular space is as large as possible
• Position sought at rest or following acute trauma to accommodate maximal fluid accumulation
• Unlocked, statically inefficient for load bearing and dynamically safe
• Treatment position (used to begin treatment)

Question 10

Closed Pack Position

Answer 10

• Joint positions are most congruent
• Surrounding tissue (capsules and ligaments) are under maximal tension
• Intracapsular space is minimal
• Locked, statically efficient for load bearing and dynamically dangerous joint position
• Testing position
