Figure 8 shows group differences in force precision during static dorsi- and
plantar flexion contractions.
In the case report presented hereby, the young man had clinically clear and advanced symptoms of MTSS caused by
plantar flexion muscle overuse, and the risk factors included mechanical imbalances of feet-collapse of longitudinal medial arch and over-pronation, which are very well documented in literature, and decreased hamstrings flexibility.
For ankle
plantar flexion, an OR of 0.73 was found.

plantar flexion to active dorsiflexion.

Plantar flexion was involved in 4.5% (MRC grade 0-1).
Meanwhile the foot handles shock absorption, fast
plantar flexion, harmonic rollover, fore foot dynamics, effective foot length, torsional compliance, strength and stability.
Flexion of the knee caused dorsiflexion of the foot, and extension of the knee caused
plantar flexion of the foot.
The patient also reported that the pain was aggravated by kicking and
plantar flexion motion.
To measure the power of knee
plantar flexion muscles the knee was posited in a 90[degrees] angle (the reason for choosing the 90[degrees] angle was that according to various studies the maximum power of these muscles is produced in this position), and after contraction of these muscles by the subjects their power was recorded (U.
A typical ankle sprain is an inversion injury in
plantar flexion. The anterior talofibular ligament, which runs anterior to the lateral joint line between the calcaneus and the talus, is injured in 80% of cases.
Ankle
plantar flexion moments are produced when the Achilles tendon pulls on the heel in such a way that the toes would point if not resisted by the ground reaction force.
