To objectively prove the existence and positioning of nerve injury, a complete neurological examination and positioning must be performed on the patient.
The content of the medical examination should include the examination of the feeling center (such as the ability to judge time, place, and characters); examination of cranial nerves, motor nerves, and sensory nerves (including the feeling of the back);Inspection of reflection and anal reflection; examination of gait and cerebellum function.For example, the integrity of the sacral reflection arc (－ 2-4) can be detected through the sponge sponge body muscle reflection, pinching the glans with one hand, and placing the other hand in perineal or anal, you can feel the contraction of the muscle.In clinical examinations, SP70 % of normal men have this physical reflection.The clinical examination of the penis sensation is also useful. For example, acupuncture test and alcohol cotton ball temperature sensor test can confirm whether the sensory component of the penis back nerve is harmed.
The following will be introduced separately:
(1), ball sponge body muscle reflection
It is a bilateral, spinal cord, and physical reflection.The introduction of this reflex arc and the rumors of nerve fibers come from the genital nerve, and its reflection center is located in the second and third sections of the ingredients.As early as the beginning of this century, people knew that when the back of the penis and glans was used to apply a little pressure, this reflection could be led.It shows the contraction of the sponge body muscles and anus sphincter, and the naked eye can observe the JU shrinkage of the post -muscle group.This reflection can also be quantitatively measured by more reliable electrical stimulus and muscle diagram records.
(2) Scrotum reflection
It is a shaft and local reflection.When a man naked in a cold house, this phenomenon can often be noticed.This reflection is a slow and peristaltic contraction of the scrotum meat membrane muscles.When a cold object is placed in the scrotum, perineum, or the upper part of the thigh, this reflection can be led.This reflection disappears when patients have muscle or local nerve lesions.
(3), the potential measurement measurement
The measurement of the potential potential potential is actually a electrical determination of the above -mentioned electrical biological reflection activity of the sponge sponge body muscle. When conducting this test, you need to place a ring electrode on the penis glans. Through this electrodeThe needle -shaped electrodes on the sponge body muscle and the electrocardiography connected to it to record the reflection of the sponge body muscles. This test measures the time from the stimulation of the penis glans to the sponge body muscleEssenceThe average ball sponge muscle reflection incubation time of a normal -erection ability is 35.0 ± 1.2 milliseconds (28-42 milliseconds). This is the most widely used test indicator in neurophysiology.It is a multi -sudden reflection with a cross -and -right cross, which stimulates one side to cause the incubation reaction of the same and opposite side.The test is used once every second, and each time it continues to bake 氲 氲 氲 氲 氲 龀 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 试 甭龀 甭龀 甭龀 试 试 increases from 30 volts to 60 volt or 6 mAhMost patients can confirm the electrical stimulus or sensory threshold that the first perception is
(4), shallow anus reflection
It is a bilateral, body, and wattian car porcelain 洌 浞 嘣 嘣 嘣 嘣 嘣 嘣?When the skin of the perineum area is scratched, the contraction of the anus sphincter can be seen.
(5) Internal reflection
It can be used to evaluate the sympathetic ingredients in the abdominal nerve and the anterior nerve bush, and it is speculated that the central hub is located in the 2 sections of the waist baking M waist.When inserting a finger with a sleeve to the anus, this reflection can be led to the contraction of the sphincter of the anus!
(6), testing test reflection
It is a symbolic, superficial body reflection.Using the blunt head of the head to gently draw the inner skin of the thigh, this reflection can be led.The reaction is the increase in the testis of the same side.The reflection is regulated by the iliac groin and reproductive stock neural regulation, and its reflection center is located on the waist of the spinal cord 1, waist 2, and sections.This stimulating test muscle reflection appears slowly, as seen in the process of sexuality.Regardless of any part of the peripheral reflex arc or the damage of the central motor neurons, this reflection will disappear.
