Dorsiflexion is where the toes are brought closer to the shin. This decreases the angle between the dorsum of the foot and the leg. [28] For example, when walking on the heels the ankle is described as being in dorsiflexion. [27] Similarly, dorsiflexion helps in assuming a deep squat position. [29]
A patient recovering from surgery to treat foot drop, with limited plantar and dorsiflexion.. Foot drop is a gait abnormality in which the dropping of the forefoot happens out of weakness, irritation or damage to the deep fibular nerve (deep peroneal), including the sciatic nerve, or paralysis of the muscles in the anterior portion of the lower leg.
The movements of tibialis anterior are dorsiflexion and inversion of the ankle. However, actions of tibialis anterior are dependent on whether the foot is weight bearing or not (closed or open kinetic chain). When the foot is on the ground, the muscle helps to balance the leg and talus on the other tarsal bones so that the leg is kept vertical ...
Pronation is a natural movement of the foot that occurs during foot landing while running or walking. Composed of three cardinal plane components: subtalar eversion, ankle dorsiflexion, and forefoot abduction, [1] [2] these three distinct motions of the foot occur simultaneously during the pronation phase. [3]
The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed.It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it.
For example, plantarflexion occurs when pressing the brake pedal of a car. Palmarflexion and dorsiflexion refer to movement of the flexion (palmarflexion) or extension (dorsiflexion) of the hand at the wrist. For example, prayer is often conducted with the hands dorsiflexed.
The ankle dorsiflexion is a result of the tibia moving forward over the foot and is facilitated by eccentric control provided by the soleus. [ 5 ] [ 11 ] Concurrently, the knee reaches full extension and as the heel rises off the ground the ankle begins to plantar flex.
The barbell back squat Bodyweight squat. A squat is a strength exercise in which the trainee lowers their hips from a standing position and then stands back up. During the descent, the hip and knee joints flex while the ankle joint dorsiflexes; conversely the hip and knee joints extend and the ankle joint plantarflexes when standing up.
