composite sensory test

The composite sensory examination includes a skin positioning sensation examination, a two-point discrimination sensation examination, a graphic sensation, and a physical sensation examination. These sensations are the result of brain synthesis, analysis, and judgment, so they are also called cortical sensations. Skintopethesia is a test for determining the ability to sense tactile sensation. The physician touches the skin with a finger to let the patient indicate the position of the touch by hand. Skin dysfunction is seen in cortical lesions. Before you check, you should prepare the items you want to use during the test, such as pencils, erasers, keys, compasses, etc. Basic Information Specialist classification: neurological examination classification: neuroelectrophysiology Applicable gender: whether men and women apply fasting: not fasting Tips: Pay attention to rest and diet before the test, and maintain a stable mood. Normal value 1, skin positioning sense check normal people can accurately point the location of the touch. 2, two points to distinguish the feeling of the normal person's discrimination threshold is small. 3, the graphic sense check normal people can correctly identify the graphics drawn on the skin. 4. When the entity senses the inspection, the normal person can correctly identify the size, shape and nature of the physical object on the hand. Clinical significance Abnormal results: 1. Skin dysfunction is seen in cortical lesions. 2, two points of discrimination disorders found in frontal lobe lesions. 3, the pattern of dysfunction prompted for lesions above the level of the thalamus. 4, when the physical sense is missing, the patient can not distinguish what is the object, can be seen in the cortical lesions. People in need of examination: patients with suspected cortical lesions or frontal lobe lesions, lesions above the level of the thalamus. Precautions Taboo before inspection: Prepare the items to be used for testing before the test, such as pencils, erasers, keys, compasses, etc. Requirements for inspection: 1. Graphical awareness, two-point discrimination, and skin positioning are required to close the eyes. 2. When checking, it is required to correctly describe the size and shape of the object or figure that you feel, or point out the stimulation part with your finger. Inspection process 1. Skin orientation (skintopethesia) is a test for determining the ability of tactile locating. The physician touches the skin with a finger to let the patient indicate the position of the touch by hand. Skin dysfunction is seen in cortical lesions. 2. Two-point discriminating The patient closes his eyes and stimulates the two skins with separate feet. If the patient has two feelings, the distance between the two feet is shortened until the patient feels a little. The sensitivity of the two parts of the body to the two points is different, with the tip of the tongue, the nose and the fingers being the most obvious, and the proximal extremities and the trunk are the worst. If the touch is normal and the two points are different, it is seen in the frontal lobe. Not suitable for the crowd Inappropriate crowd: 1. Physical sensation: A patient with a disability or injury to the upper limb. 2, graphic sense, two points of discrimination, skin positioning: patients with severe skin damage. Adverse reactions and risks Nothing.
