Middle stage

Open kinetic chain exercises are associated with...

• The distal segment of the extremity moving freely

• The distal segment of the extremity being fixed

• The distal segment being weight bearing

• Higher joint congruity

Closed kinetic chain exercises are associated with...

• Large acceleration forces and low resistance forces

• The distal segment of the extremity being fixed

• The distal segment of the extremity being free to move

• Higher compressive forces

Core involvement in the kinetic chain is important...

• True

• False

A squat is a closed kinetic chain exercise for the lower limb

• True

• False

In the middle stage we should not use weight-bearing exercises

• True

• False

An important aim of the middle stage of rehab is...

• Strengthen the affected muscle only

• Get back 2/3 ROM

• Improve pain-free muscle contractions

• Decrease swelling

In the middle stage our athletes can...

• Stop training unaffected areas

• Return to ballistic loading

• Start sprinting

• Start throwing

Ballistic loading is characterised by...

• Movement being performed with maximum velocity

• Very little control over the movement

• Erratic movements

• Maximal concentric contractions

We should consider training synergists in the middle stage of rehab

• True

• False

Which of the following is NOT an aim of the middle stage?

• Increase muscle load

• Strengthen synergists

• Re-introduce sprinting

• Return to ballistic loading
