Drunk gait

Introduction The drunken gait is difficult to control because of the center of gravity. When walking, the distance between the legs is widened. After lifting the leg, the body swings to the sides. The upper limb often shakes in the horizontal direction or before or after, and sometimes it cannot stand stably. Take a straight line. When the cerebellum or vestibular system is damaged, the muscles of the upper and lower limbs are weakened, the distance between the upper limbs is poor, or the balance of the trunk is poor. Therefore, the stride is large, the step is widened, and the trunk is shaken and drunk. Ataxia is caused by many parts of the nervous system.

Cause

The drunken gait is mainly used to diagnose cerebellar or vestibular system disorders. Found in cerebellar tumor, cerebrovascular disease, tumor, inflammation, degeneration, cerebellopontine angle tumor, olive bridge cerebellar degeneration, alcoholic cerebellar degeneration, cancerous spinal cerebellar degeneration J brain atrophy J encephalitis, brain stem Tumor, posterior inferior cerebellar artery thrombosis, frontal lobe lesion, inner ear vertigo, vestibular neuronitis, etc.

When the cerebellum or vestibular system is damaged, the muscles of the upper and lower limbs are weakened, the distance between the upper limbs is poor, or the balance of the trunk is poor. Therefore, the stride is large, the step is widened, and the trunk is shaken and drunk.

Brain CT examination of nervous system examination posture and gait

Physical examination

The patient can be walked normally during the examination and closed eyes if necessary. Further examination can cause the patient to suddenly turn, stop, and so on. Pay attention to the conditions of starting and stopping, the posture of stretching and falling, the size of the steps, the rhythm and the direction.

2. Auxiliary inspection

Gait abnormalities select different auxiliary tests depending on their nature and location.

The drunken gait is more common in cerebellar lesions. The brain CT or MRI is more clinically selected. If brain stem MRI is considered for brain stem involvement, it can also be supplemented with EEG.

Differential diagnosis

Duck gait: When walking, the waist is bulging, and the hips swing like a duck.

Scissors gait: the legs are stiff, the two legs are crossed inward, the knees are close to the scissors, the walking gait is small and slow, and the ball is often striking like a ballet.

Rooster gait; when standing, the two thighs are close, the calves are slightly separated, the feet stand like toes, and when walking, the ballet is like a pointed walk.

Jumping gait: When the knees are kneeling, the two knees cannot be closed together, the legs must be separated, and the hip joints on both sides are abducted and externally rotated, just like the hind limbs when the frog is flexed; when standing, the lower limbs are slightly externally rotated, which cannot be completely Close together, it is "outside eight characters"; when walking, it is "eight characters" squatting gait; when walking fast, because the hip flexion is limited, the gait is jumping, so it is called jumping.

Observe the patient's performance when walking. If you see that the foot is slow, the force is too heavy, and the foot is floating forward and forward. When landing, it is full of foot, the gait is dim, the whole body is swaying, and the shape is drunk. Han gait.
