SESSION 18
Foot Musculature
Objectives
To deduce muscle actions, discuss stability vs mobility, and discuss structure and function relationship of the foot.
The foot is one of the most essential structures to the PT since adjusting gait/running forces (and correcting higher joints) can be done sometimes simply with shoes or inserts.
Pin the muscle on the foot layer!
With your 3 person group, create these structures on the following slide:

Stability vs. Mobility
Increase stability Increase MobilityStrong, tight ligaments Lots of jointsLow ROM for each joint Low amount of fatBones fit together tightly Tibiotalar joint & MTP jointsLots of muscles & tendons
Structure & Function
PositivesProtective of
neurovasculatureEffective force
transferenceEffective for gait
NegativesLots of dysfunctions!
Common Problems
Talotarsal dislocation – talus rotates medially, foot rotates laterally
Common Problems
HammertoeHallux Valgus (Bunions)Pes Planus (Flatfeet)Plantar Fasciitis
Common Problems
Tibial Nerve Entrapment
Medial Plantar Nerve Entrapment (Jogger’s foot)
Objectives
To deduce muscle actions, discuss stability vs mobility, and discuss structure and function relationship of the foot.
The foot is one of the most essential structures to the PT since adjusting gait/running forces (and correcting higher joints) can be done sometimes simply with shoes or inserts.
Your patient stepped on a nail that went between the 1st and 2nd metatarsals. What functions will be most affected?
(ignoring the affect of pain)
A. Flexion of the big MTP joint
B. Flexion of the 2nd MTP joint
C. All movements of the 2nd MTP joint
