We are still covering muscles of the "deep posterior compartment of the lower leg"
-deep meaning closest to the bone
-posterior meaning on the back of the leg
Tibialis Posterior is aka "Tom" of Tom, Dick & Harry
,a group of 3 deep posterior lower leg muscles that share the same actions. These three
are often tight and need a good massage (especially runners!)
So deep that they live underneath the gastroc & soleus muscle (the more popular calf muscles we see) 'Tom' is also the largest of the three:
Tibialis: refers to its attachment point on the Tibia (leg bone)
Posterior: on the back
TIBIALIS POSTERIOR MUSCLE ATTACHMENTS:
ORIGIN: the proximal 2/3 of the posterior tibia, fibula and interosseus membrane*
*a connective tissue that stretches between the tibia & fibula (lower leg bones)
INSERTION: navicular, cuneiforms, cuboid, and bases of 2nd thru fourth metarsals
*you can see why we include your foot as part of a lower leg treatment - many clients come in with a lower leg injury but say that foot massage is not necessary,
Let's take a closer look at those insertion points on the Bottom of the foot!
TIBIALIS POSTERIOR MUSCLE ACTIONS:
1- plantar flexion of the foot at the ankle joint:
2- inversion of the foot at the subtalar joint:
kinda similar eh? I think you can help but invert a lil' whilst you plantar flex ;)
Next week we'll cover ' DICK' of
Tom Dick & Harry
Tom = Tibialis Posterior
Dick = Flexor Digitorum Longus
Harry = Flexor Hallucis Longus
'gangs all here'
....speaking of.... remember that 90s comedy 3rd rock from the sun?
ever notice that the 3 guys names are
Tom, Dick and Harry ?!?!
Because they're aliens and just trying to fit in...
like every other 'Tom Dick & Harry' !
Haha Harry was the weird one..
