Subtalar Joint Axis Rotational and Translational Motions During Closed Kinetic Chain Pronation and Supination - Sagittal Plane Motion In this three dimensional animation of the medial view of the weightbearing foot skeleton during closed kinetic chain subtalar joint (STJ) pronation and supination, the STJ axis is noted to undergo plantarflexion during pronation and dorsiflexion during supination. As the talus plantarflexes during STJ pronation, note how the STJ axis plantarflexes along with the

Flexion and extension of the trunk refer to movements of the spine in the sagittal plane. Trunk flexion: Bending forward, decreasing the angle between the thorax and pelvis. This primarily involves the rectus abdominis, external and internal obliques, and psoas major. Trunk extension: Straightening or arching the back backward, increasing the angle between the thorax and pelvis. This is primarily driven by the erector spinae (iliocostalis, longissimus, spinalis) and multifidus. These movements o

The three movements in the spine are flexion, extension, rotation and lateral flexion. These movements occur as a combination of rotation and translation in the sagittal, coronal and horizontal plane. Movements result in force, a force simply being a push or pull. #drmuhammedziya #spine #humananatomy #thoracic #thoracicmobility #lumbar #lumbarsupport #flexion #rotaion #iskeleton #discoverme | Dr. Muhammed Ziya
