lecture 7: therapeutic exercise for the ankle and foot Flashcards
what are the primary motions of the talocrural joint
DF and PF
during OKC supination and pronation what is the motions of the foot
sup: calcaneus PF , add and inversion
pro: calcaneus DF , ADB and eversion
during CKC supination and pronation what is the motions of the foot
SUP: calcaneal inversion , talus abd and DF
pro: calcaneal eversion , talus add and PF
what is included int he bifurcate ligament and when is it injured
calcaneonavicular ligament
calcaneocubdoid ligament
what 4 ligaments are included in the deltoid ligament
posterior tibiotalar
tibiocalcaneal
tibionavicular
anterior tibiotalar
what are the primary plantar flexors
Gastrocnemius
Soleus
Plantaris
what are the secondary plantar flexors
Posterior Tibialis, FDL, FHL
Peroneal longus and brevis
what is the primary and secondary DF
Anterior Tibialis (primary)
EHL
EDL
Peroneal tertius
what does the tibial nerve break off into
medial calcaneal nerves
inferior calcaneal nerves
lateral plantar nerve
medial plantar never
what mms are responsible for eversion of the foot
Peroneal longus
Peroneal brevis
Peroneal tertius
what mms are responsible for inversion of the foot
tib ant and post
what are included int he foot intrinsic dorsaly
EDB
EHB
what is the function fo the foot intriniscis
toe motion and arch stability
what are the 4 layers of the foot intrinsics plantarlly
Layer 1 (superficial): Abductor Hallucis, FDB,
Abductor DM
Layer 2: Quadratus Plantae, Lumbricals
ayer 3: FHB, Adductor Hallucis, FDMB
Layer 4: Plantar Interossei, Dorsal Interossei
in CKC tibial IR and ER is associated w what at the foot
IR= pro
ER= sup
as the heel strikes the ground there is slight ___ and as at the foot lowers to the ground there is __- to absorb some of the impact of the ground)
sup
pro
as the foot is fixed on the ground and the tibia comes up over the foot what happens at the ankle
DF
tibia IR , reinforces pronation of the foot
what happens at the tibia and hind foot during instance thru terminal stance
tibia ER
initiating supination of hind foot , locking transverse tarsal joint (foot is in closed packed position)
what is claw toe
MTP hyperextension and IR flexed
what is hammer toe
MTP hyperextension
PIP flex
DIP hyperextension
what is the MOI for a lateral ankle sprain
inversion and PF
if you are examining an ankle after an inversion and PF MOIn and there is a slight stretching and microscopic tearing of the ligament fibers , they have some mild tenderness and swelling around the ankle what grade would u suspect and what lig is prob injured
grade 1 sprain (mild)
anterior talofibular ligament
what is a grade 2 sprain (moderate) of a lateral ankle
partial tearing of anterior talofibular lig and some tearing of the calcaneofibualr lig
mod tenderness and swelling
recover in 2-3 weeks
what is a grade 3 lateral ankle sprain (severe)
complete tear for the ATFL , CF and PTFL
sig tenderness and swelling around the ankle
takes 3-12 weeks to recover
if a pateint comes in and their MOI is forced eversion and DF of the ankle wha kind of sprain are u thinking
syndesmotic ankle sprain (high ankle sprain)
what is the most common ligament that is invovled in the syndesmotic ankle sprain
anterior interior tibiofibular ligament
what are teh S/S for a syndesmotic ankle sprain
less swelling , inability to bear weight , inability to fully PF and ecchymosis
what is the MOI of a medial ankle sprain
eversion
