Ataxia testing

Any simple movement requires the precise cooperation of four groups of muscles: active muscle, antagonist muscle, synergistic muscle and fixed muscle. It can be accurately coordinated, mainly relying on the cerebellum, vestibular system, deep sensation, and extrapyramidal system. Regulation, when the above structure occurs lesions, movement coordination disorder, called ataxia (ataxia), ataxia check is to determine whether the patient has a presence of ataxia symptoms. Basic Information Specialist classification: neurological examination classification: neuroelectrophysiology Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: Ataxia is caused by lesions in the cerebellum, vestibular system, posterior root of the spinal cord, posterior cord, and brain. The lack of correctness, coordination and balance disorders in casual exercise can be seen in the following diseases. (1) deep sensory ataxia (posterior spinal cord and posterior cord ataxia) as seen in spinal cord spasm, combined sclerosis, Friedreich disease, spinal cord tumor, polyneuritis and thalamus, parietal lobe Lesion. (2) Cerebellar ataxia can be seen in the lesions of the cerebellum itself or in the neural structure associated with the cerebellum. Such as cerebellar sacral lesions, found in tumors, alcoholism, etc.; one side of cerebellar hemisphere lesions are more common in tumors, such as astrocytoma, metastases, tuberculoma or abscess; whole cerebellar lesions are most common in cerebellar degeneration and atrophy, such as Mali Hereditary ataxia, olive body, bridgehead, cerebellar atrophy, etc. (3) vestibular, labyrinthine ataxia is seen in the vestibular or semicircular canal lesions of the inner ear. (4) Cerebral ataxia is seen in the cerebral cortex motor area or basal ganglia lesions, such as frontal lobe and temporal lobe tumors. Tips: Maintain normal diet and schedule, pay attention to knee and wrist protection before closing the walking test, in-situ test, cross-walk test to prevent injury during falls. Before the nose test, the nail should be cut short and cut to prevent the face from being scratched. Normal value The results of the various tests of ataxia are negative. For example, the sniper test is accurate and the speed is fast; the normal person is flexible and coordinated when the foot is in place; the normal walking person can walk forward steadily in the cross-walking test, etc., and the ataxia can be seen in detail. Various inspection items. Clinical significance Abnormal results: Ataxia is caused by cerebellum, vestibular system, posterior root of spinal cord, posterior cord and brain. The performance of casual sports lacks correctness, coordination and balance barriers. Can be seen in the following diseases. (1) deep sensory ataxia (posterior spinal cord and posterior cord ataxia) as seen in spinal cord spasm, combined sclerosis, Friedreich disease, spinal cord tumor, polyneuritis and thalamus, parietal lobe Lesion. (2) Cerebellar ataxia can be seen in the lesions of the cerebellum itself or in the neural structure associated with the cerebellum. Such as cerebellar sacral lesions, found in tumors, alcoholism, etc.; one side of cerebellar hemisphere lesions are more common in tumors, such as astrocytoma, metastases, tuberculoma or abscess; whole cerebellar lesions are most common in cerebellar degeneration and atrophy, such as Mali Hereditary ataxia, olive body, bridgehead, cerebellar atrophy, etc. (3) vestibular, labyrinthine ataxia is seen in the vestibular or semicircular canal lesions of the inner ear. (4) Cerebral ataxia is seen in the cerebral cortex motor area or basal ganglia lesions, such as frontal lobe and temporal lobe tumors. People who need to be examined: patients with unstable walking, ataxia symptoms or suspected cerebellar lesions. Positive results may be diseases: spinal cord tumor, polyneuritis, olivopontocerebellar cerebellar atrophy, brain tuberculoma, astrocytoma, pediatric hyperactivity, prefrontal cancer considerations Pre-inspection contraindications: Maintain normal diet and schedule, observe the knee and wrist protection before closing the walking test, in-situ walking test, and cross-walking test to prevent injury during falls. Before the nose test, the nail should be cut short and cut to prevent the face from being scratched. Requirements for examination: doctors should try to relax as much as possible, do not be too nervous, actively cooperate with the doctor's work, pay more attention to prevent falling when closing the eye test, in-situ test, cross-walk test. Finger nose test should prevent puncture of the eyes when blinking. Inspection process Observe the patient's daily movements, such as eating, dressing or undressing, unbuttoning buttons, taking things, standing, walking, etc. The movement of the limbs is accurately coordinated. If the movements are inaccurate and uncoordinated, it should be considered to have ataxia. In order to accurately determine the extent, the following checks can be made: (1) Finger nose test: The paralyzed patient straightens the upper limb first, then touches the tip of his nose with his index finger. During the test, first blink the eye and then close the eye to do this action. If the limb is slow and awkward, the finger will sway or tremble when it is active, and it cannot be accurately pointed to the tip of the nose. (2) Rotational exercise test: The paralyzed patient performs a quick flip motion with both hands. If the limb movement is slow and awkward, it is positive for the test. (3) Heel knee test: The patient is lying on his back, lifting his lower limb, placing the heel on the knee of the contralateral lower limb, and then sliding down the front of the humerus. If the heel cannot be accurately placed on the knee, Can not slide straight down the tibia, which is positive for the test. (4) Tracing test: When the patient is in the supine position during the examination, he or she draws a triangle, a circle or a square in the space. If the athlete cannot complete the exercise, the test is positive. (5) Whitening test: The patient is standing upright, the two feet are close together, and the hands are stretched forward. When blinking and closing the eyes, pay attention to whether they have a tendency to sway or tilt. If there is a swing or dump phenomenon when the eyes are closed, it is a test positive, which is also called a closed eye. Not suitable for the crowd Inappropriate population: Patients with disabilities on their limbs or disease. Adverse reactions and risks Nothing.
