This plantar flexion movement is controlled eccentrically by the ankle dorsiflexors. [5] As the body glides over the fixed foot, a maximum of about 10 degrees of ankle dorsiflexion is reached. The ankle dorsiflexion is a result of the tibia moving forward over the foot and is facilitated by eccentric control provided by the soleus.
Those in the lateral compartment only have weak participation in plantar flexion though. The range of motion for plantar flexion is usually indicated in the literature as 30° to 40°, but sometimes also 50°. The nerves are primarily from the sacral spinal cord roots S1 and S2. Compression of S1 roots may result in weakness in plantarflexion ...
The plantar reflex is a reflex elicited when the sole of the foot is stimulated with a blunt instrument. The reflex can take one of two forms. The reflex can take one of two forms. In healthy adults, the plantar reflex causes a downward response of the hallux ( flexion ).
The ankle, the talocrural region [1] or the jumping bone (informal) is the area where the foot and the leg meet. [2] The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint. [3] [4] [5] The movements produced at this joint are dorsiflexion and plantarflexion of the ...
Flexion and extension are movements that affect the angle between two parts of the body. These terms come from the Latin words with the same meaning. [a] Flexion is a bending movement that decreases the angle between a segment and its proximal segment. [9] For example, bending the elbow, or clenching a hand into a fist, are examples of flexion ...
The movements permitted in the metatarsophalangeal joints are flexion, extension, abduction, adduction and circumduction. Left: toes adducted (pulled towards the center) and spread (a b ducted); right, both feet clenched (plantar flexed)
The fibularis brevis (bottom-most label) is a muscle of the lower leg and aids in plantar flexion and eversion of the foot. The fibularis brevis arises from the lower two-thirds of the lateral, or outward, surface of the fibula (inward in relation to the fibularis longus) and from the connective tissue between it and the muscles on the front and back of the leg.
Dorsiflexion (extension) and plantar flexion occur around the transverse axis running through the ankle joint from the tip of the medial malleolus to the tip of the lateral malleolus. Pronation (eversion) and supination (inversion) occur along the oblique axis of the ankle joint.
