A dragging gait of the lower extremities is a clinical manifestation of corticospinal tract lesions in gait abnormalities. In corticospinal tract lesions, spastic hemiplegic gait is a unilateral lesion. The upper extremity of the diseased side is usually in a flexed, pronated position, with the lumbar region tilted to the healthy side, while the lower extremity is straightened and externally rotated, with outward forward swing compensating for the weakness of the hip, knee flexors and ankle dorsiflexors. What are the symptoms that are easily confused with it? 1, cross-threshold gait The common peroneal nerve is composed of L4-S3, and its injury causes dorsiflexion, abduction and adduction of the foot, impaired toe extension, and sensory impairment of the anterolateral calf and dorsal foot. 2, “duck gait” gait severe pseudohypertrophy dystrophy is a clinical manifestation type of muscular dystrophy, manifested as two feet skimming, walking slowly swaying, a special “duck gait” gait. Myotonic dystrophy is a group of primary skeletal muscle necrosis disorders characterized by progressive skeletal muscle weakness due to genetic factors, which manifests clinically as progressively increasing skeletal muscle atrophy and weakness of varying degrees and distribution. It may also involve the heart muscle. 3, hysterical gait Gait abnormalities can be caused by motor or sensory disorders, and its characteristics are related to the site of the lesion. Hysterical gait: can show strange gait, although the lower limb muscle strength is good, but can not support the weight, swaying in all directions and seem to fall, walking with assistance gait dragging, but rarely fall caused by injury. See in cardiac diseases. 4, drunkard’s gait drunkard’s gait because the center of gravity is not easy to control, when walking with a wider spacing between the legs after lifting the legs of the body swayed to both sides unstable, the upper limbs are often swayed to the horizontal direction or before or after sometimes can not stand stable, change position when the instability is more obvious can not walk straight. 5, rooster gait rooster gait; standing with the two thighs close together, the lower legs slightly apart, feet like toe standing, walking like a ballet-like tip walk. 6, waddling gait waddling gait is a typical abnormal gait. When walking, the body sways from side to side, duck-like gait. Commonly seen in neurological disorders, rickets, macrosomia, progressive muscular dystrophy or bilateral congenital hip dislocation, etc. 7, swaying gait Duck gait or swaying gait, is a common sign of congenital medullary dislocation, unilateral dislocation appears lameness, bilateral dislocation, standing pelvis forward, hips shrugging, waist convexity, abdominal bulge, walking left and right swaying so called duck gait or swaying gait, walking a little faster, that is, easy to fall.
