Relative joint angular displacements were calculated for the subtalar
, ankle, knee and hip (180[degrees] in full extension), along with angular velocities and accelerations.

Inversion and eversion occurs at the subtalar
joint, which is between the talus and calcaneum.
The risk of injury increases due to a number of exaggerated factors such as Q angle, tibial torsion, femoral anteversion, subtalar
pronation, anterior pelvic tilt, and genu recurvatum compared to male athletes of the same age (Silvers & Mandelbaum, 2007; Shultz et al., 2008).
In studies of Toda (19,20) the effect of a lateral-wedge insole with subtalar
stapping on VAS scores, femorotibial angle and Lequesne Index scores was significantly better compared to inshoe lateral-wedge insole in patients with varus deformity OA of the knee.
The laxity in the joint capsule and ligaments of the subtalar
and midtarsal joints is usually caused by inflammation and swelling.
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
(1) Its functions include lateral stabilization of the ankle, weight bearing by means of its articulation with the fibula, and subtalar
Recent examples include Exactech's acquisition of Altiva, which represented the culmination of investments starting in 2003 that now provides Exactech with an expanded presence in spine as well as biologics; Synthes' introduction into dynamic stabilization technology through its acquisition of venture-backed N-Spine, with at least 60% of the purchase price payable on achievement of milestones; and Wright Medical enhancing its ankle and foot portfolio with the purchase of subtalar
implant assets from Metasurg, with much of the purchase price being performance based.
To determine whether a runner would benefit from orthotics, the first step is to examine the foot when it's not bearing weight and when it's in the "subtalar
neutral" position--neither pronated nor supinated.
To determine whether a runner would benefit from orthotics, one should first examine the foot when it's not bearing weight and when it's in the subtalar
neutral position neither pronated nor supinated.
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.
