ankle reflex

Abnormal sputum reflex This reflex is a physiological reflex. When it is extremely hyperactive, it is often accompanied by a hernia, suggesting a pyramidal lesion. When the sciatic nerve is damaged, the lumbar disc is prolapsed, the sciatic neuritis, and the sacral nerve are paralyzed, the tendon reflex is weakened or disappeared. The patient was placed supine, the hips and knees were slightly flexed, and the lower extremities were taken out of the external rotation. The examiner used the left hand to gently support the patient's sole, so that the foot was overstretched, and the right hand was used to slap the Achilles tendon. Basic Information Specialist classification: neurological examination classification: neuroelectrophysiology Applicable gender: whether men and women apply fasting: not fasting Reminder: Before the examiner checks, the patient should be completely relieved to avoid affecting the test results. Normal value The normal reaction is contraction of the gastrocnemius muscle and flexion of the foot to the face. Clinical significance Abnormal results: The sputum reflex is often accompanied by a hernia, suggesting a pyramidal lesion. When the sciatic nerve is damaged, the lumbar disc is prolapsed, the sciatic neuritis, and the sacral nerve are paralyzed, the tendon reflex is weakened or disappeared. People who need to be examined: patients with sciatic nerve damage, lumbar disc herniation, sciatica, and sacral nerve palsy. Precautions Pre-examination contraindications: Before the examiner checks, the patient should be completely relieved to avoid affecting the test results. Requirements for inspection: 1. When the lying position cannot be measured, it can be checked on the chair. 2, the examiner should be moderate in the percussion of the Achilles tendon to prevent the patient from hitting. 3. Pay attention to the firmness of the chair when checking on the chair surface to prevent it from falling off the chair. Inspection process The patient was placed supine, the hips and knees were slightly flexed, and the lower extremities were taken out of the external rotation. The examiner used the left hand to gently support the patient's sole, so that the foot was overstretched, and the right hand was used to slap the Achilles tendon. The normal reaction is contraction of the gastrocnemius muscle and flexion of the foot to the face. If the lying position cannot be measured, the patient can be squatted on the chair, the feet are suspended by the side of the chair, and then the Achilles tendon is smashed and the reaction is the same as before. The reflection center is 1 to 2 knots in the iliac pulp. Not suitable for the crowd Inappropriate population: Patients with lower limbs, illness, or injury. Adverse reactions and risks Nothing.
