Three Joints Must Work Together
S M S M S M
Foot is planted, Knee is mobile (3-10 rotation)
Foot rotates, Knee must remain stable

What happens when the Three joints dont work together
Mobile
Mobile
Stable
Tight hip muscles prevents mobile movement, movement is transferred to knee

PCL
ACL
ACL Tear
-
Degenerative Knee
-
Ankle Injuries
Swollen ankle, Achilles tendonitis
-
Retinacula
Peroneus longus muscle
Peroneus brevis muscle
Common sheath of peroneus longus and brevis tendons

Wheres the injury?
-
Peroneal Tendonitis

Stretch & Mobilization
-
Strengthen The Movement
-
Stabilize Without Delay
-
Energy does not dissolve, it transfers.
Remember M-S-M and S-M-S relationships.
Maintain healthy joint relationships with flexibility exercises.
Braces slow natural movement and interfere with balance and reaction time.
