Q

What is the foot transition relating to stability during the gait cycle?

A

From heel strike to accepting body weight moves into pronation, forfeiting some stability in exchange for mobility.
As it pushes off, moves back into supination, favoring stability.

Q

How can a determination be made about open-close chain exercises considering force applied?

A

Closed-chain - Force applied to surface, boy moves instead of equipment.
Open-chain - Force applied moves the limb farthest from body as well as weight of equipment.

Q

What are some advantages of closed chain over open chain exercises?

A

Closed chain emphasizes compression of joints, helping with stabilization.
Closed-chain involve more muscles and joints, leading to better neuromuscular coordination.

Q

What are shearing forces?

A

A force that causes slippage between a pair of contiguous joints or tissues in a direction that parallels the plane in which they contact.

75
