Development of a 3D active movement extent discrimination apparatus for testing proprioception at the ankle joint with inversion movements made in plantarflexion.

Proprioception plays an important role in joint stability, and ankle sprains usually happen involving plantarflexion, internal rotation, and inversion. However, ankle 3D movement proprioception has never been measured in weight-bearing. Accordingly, the active 3-dimensional movement extent discrimination apparatus (AMEDA-3D) was developed and its reliability and validity were investigated.

Decoupling of muscle-tendon unit and fascicle velocity contributes to the in vivo stretch-shortening cycle effect in the male human triceps surae muscle.

During the shortening of stretch-shortening cycles (SSCs), muscle force output is enhanced compared with pure shortening (SHO), referred to as the SSC-effect. In general, muscle-tendon unit (MTU), muscle belly, muscle fascicle, and tendon length changes can be decoupled during contraction, which affects force generation and elastic recoil. We researched whether MTU decoupling contributes to the SSC-effect.
