1 - FUNCTIONAL ANAT OF LL Flashcards
Name & draw all the bones of foot and legs
Image
Name and draw all the joints & ligaments of foot
Image
What would improve OCK on talus
Do anterior glide with elastic on calcaneus
What happens in ankle during DF?
- more stability in ankle
- Less lateral ROM
- could lead to dislocation or fracture
In single leg stance, what happens in arch of foot
Arch o drop, navicular drop down
Description of lisfranc joint
- More risk having OA
- Provide support on medial side
- Pain & instability = symptoms of this joint. Then X-ray for
10 days after: weight bearing Xray for see grasping - No bleeding but swelling at malleolus level
- Excessive plantarflexion can cause rupture of ligament (injured lateral ligament at same time)
=> so often missed
Name the foot’s muscles of superficial layer
Table
Name foot’s muscles of middle layer
Table
Name foot’s muscle of deep layer
Table
Show picture and describe the functional anatomy of different postures
Table
What are the 2 main function roles of muscles ?
MUSCLE FUNCTION ROLES
- Fixators: muscles stabilizing joint positions
- Changing roles: muscles adapt functions based on movement context
Name the 2 main phases of gait cycle & all the sub step within phases
Image
Looking at gait cycle in sagittal plane:
- %
- ankle position
- knee position
- hip position
Of each phases
Table
What happens in knee & ankle in frontal plane during gait cycle
Description of stance & swing phase in terms of movements
60% of gait cycle => varus then come back to valgus
Ankle: valgus / varus
Knee: varus / valgus
Stance = slight adduction + upward movement of pelvis at end of DS, going down during SS
Swing = slight abduction, downwards movement of pelvis until terminal swing / preparation of IC
Joint moments in ankle, knee & hip:
- initial condition
- loading response
- mid stance
- terminal stance
Table
Meaning of ext M & int M
Ext M = external moment = forcing outside of body acting on it
Int M = internal moment = reaction of body to external forces
EMG activity of ankle
Table
EMG activity of knee
Table
EMG activity of hip

Name the different tensegrity concepts
Superficial back line
Superficial front line
Spiral line
Lateral lines
Functional lines
Superficial back line:
- path
- functions
- muscle type
