Ankle Flashcards
Ankle dorsiflexion
Testing position: sitting with hip and knee flexed 90º and foot in 0º inversion and eversion
Stabilization: tibia and fibular to prevent hip and knee motion
Axis: lateral malleolus
SA: lateral midline of fibula using head of fibula for reference
MA: parallel to lateral midline of fifth metatarsal
AAOS: 20º
Ankle plantarflexion
Testing position: same as non weight bearing ankle dorsiflexion
Stabilization: tibia and fibula to prevent hip and knee motion
Axis: lateral malleolus
SA: lateral midline of fibula using head of fibula for reference
DA: parallel to lateral midline of fifth metatarsal
AAOS: 50º
Inversion:
ROM
testing position: sitting with hip and knee flexed 90º; hip in neutral rotation and abduction
- Axis: anterior aspect of ankle midway between malleoli
- SA: anterior midline of lower leg using tibial tuberosity as reference
- MA: anterior midline of second metatarsal
- AASO: 35º
Eversion
testing position: sitting with hip and knee flexed 90º; hip in neutral rotation and abduction
Stabilization: tibia and fibular to prevent knee flexion and hip medial rotation and adduction
Axis: anterior aspect of ankle midway between malleoli
SA: anterior midline of lower leg using tibial tuberosity as reference
MA: anterior midline of second metatarsal
AASO: 15º
toe MTP flexion
Testing position: Supine or sitting with ankle in neutral; MCP joint in 0° abduction and adduction
stabilization: Metatarsal to prevent plantar flexion of ankle and inversion or eversion of foot
Axis: Dorsal aspect of MCP joint
SA: Dorsal midline of metatarsal
MA: Dorsal midline of proximal phalanx
AAOS: 45
MTP extension
Testing position: Supine or sitting with ankle in neutral; MCP joint in 0° abduction and adduction
Stabilziation: Metatarsal to prevent dorsiflexion of ankle and inversion or eversion of foot
Axis: Dorsal aspect of MCP joint
SA: Dorsal midline of metatarsal
MA: Dorsal midline of proximal phalanx
AAOS: 70
Gastocnemius MMT
Position: Stand on test limb, knee extended, foot flat on floor (Pt to rest on hand on table for balance)
Movement: Rise on toes through full ROM(Daniels & Worthingham grades)
- Normal 5: raises from floor through full ROM 4-5 times Good
- 4: raises 2-3 timesFair
- 3: raise 1 time
OR
Position:
AG – prone, knee extended, foot over edge of table
GM – side lying Movement: ankle plantar flexion
Resistance: plantar surface of rear foot
Soleus MMT
Position: Stand on test limb, knee flexed, foot flat on floor (Pt to rest on hand on table for balance)Movement: Rise on toes through full ROM(Daniels & Worthingham grades)
- Normal 5: raises from floor through full ROM 4-5 times
-Good 4: raises 2-3 times
- Fair 3: raise 1 time
OR
Position: AG – prone, knee flexed to 90º
GM – side lying, knee flexed to 90º
Movement: ankle plantarflexion
Resistance: superoposterior aspect of calcaneus in direction of dorsiflexion
Tibialis Anterior
Position:
-AG – sitting knee flexed over table
-GM – side lying
Movement: ankle dorsiflexion & inversion
Resistance: dorsal medial aspect of foot
Tibialis Posterior
Position:
- AG – side lying, ankle slightly plantarflexed, test leg off table
- GM – supine, ankle in slight plantarflexion test leg off table
Movement: inversion through full ROM
Resistance: medial plantar aspect of foot
Peroneous longus and brevis
Position: AG – in side lying (testing leg the uppermost leg), ankle neutral
GM – supine over table edge
Movement: eversion, ankle in neutral for PF/DF
Resistance: lateral foot
Extensor Hallucis longus
Position: AG- supine or seated with ankle neutral
GM- No separate test
Movement: Extends great toe at IP joint through full ROM
Resistance: Dorsum of distal phal
