Longhorn Brain and Spine - Foot Drop

Описание: https://longhornbrainandspine.com/foo...
Also known as Drop Foot, the clinical term “Foot Drop” usually refers to a feeling of weakness in patient while lifting their foot or toes in an upward direction (Liu et al., 2013). This abnormal gait activity causes the dropping of the foot and toes. This condition usually occurs due to the weakness of muscle in the ankle and toes dorsiflexion or paralysis in the anterior part of the lower leg. The muscles of the ankle and foot include anterior tibialis, the extensor hallucis longus, and the extensor digitorum longus. This condition ultimately causes the involuntary dragging of the toes of the affected foot while attempting to walk.

Patients with foot drop usually perform high steppage or slapping gait to compensate for the dragging. Here, the patient lifts their leg higher than normal on the affected side to prevent the foot from dragging along the ground. Depending on the extent of the muscle weakness or paralysis, this condition may have a temporary nature or permanent and can affect one or both feet. People with foot drops may suffer from muscle weakness and “tingling” feelings in the leg (Gil-Castillo, Alnajjar, Koutsou, Torricelli, & Moreno, 2020).
