Forefoot valgus is when the forefoot is everted while the calcaneus and subtalar joint
are in neutral.
Physical examination of the left ankle revealed limited inversion, a rigid subtalar joint
, and weakness of the left peroneal muscles.
One of the functions of the subtalar joint
is to help absorb shock and provide a smooth transition of forces during gait.
10,18] Less medial rotation of talar head occurs in type B facet pattern leading to unstable subtalar joint
and causes osteoarthritis.
When a suitable barrier is engaged, high velocity low amplitude thrust is applied with your proximal hand to gap the subtalar joint
The treatments were intended to diminish muscle tension in the calf and mobilize the subtalar joint
Limited studies determine kinematics and kinetics in all three planes (sagittal, transverse, and frontal) where motions of the ankle joint and the subtalar joint
18] who postulated that the excessive pronation of the subtalar joint
increases the torsional forces up the tibia and fibula, producing injuries.
The observer holds the participant's heel to prevent it from lifting off the floor and manually locks the subtalar joint
so it remains in a neutral position throughout the test.
Another definition is <10o of dorsilexion with the subtalar joint
placed at neutral position.
Mobility of the subtalar joint
in the intact ankle complex.
Inversion and eversion occurs at the subtalar joint
, which is between the talus and calcaneum.
Motion at the subtalar joint
occurs in a triplanar manner during the stance phase of the gait (DelRossi et al.
In another study it was recorded that people who presented with pronated or hyper pronated subtalar joints
(STJ) demonstrated significantly higher forefoot peak pressures than people who presented with either a neutral or supinated subtalar joint
Unshod cultures have better developed lower extremities, and make better use of their subtalar joint
, the three-dimensional motion of which can convert vertical force into horizontal force upon landing.
