reflex somatic neuropathy

Introduction

Introduction to Reflex Somatic Neuropathy Reflective somatic neuropathy (also known as somatic neuropathy), reflex sympathetic dystrophy, refers to the relaxation of the lateral limbs caused by a slight trauma of the hand and foot, accompanied by obvious autonomic dysfunction. A major clinical manifestation of a disease. basic knowledge The proportion of illness: 0.0003% Susceptible people: no special people Mode of infection: non-infectious Complications: insomnia

Cause

Causes of reflex somatic neuropathy

(1) Causes of the disease

It is thought that the pathological stimuli of minor trauma such as stab wounds, cuts, drug injections or acupuncture treatments caused by the body and the deep pain fibers.

(two) pathogenesis

Pathological stimuli at the minor trauma are continuously transmitted to the spinal cord, forming pathological dominant lesions in their corresponding and adjacent spinal cord segments. When this dominant lesion is dominated by the inhibition process, it is manifested as reflex paralysis (); And when this dominant stove is dominated by the process of excitement, it is manifested as a reflexive contracture, which simultaneously affects the autonomic nerve center of the spinal cord and causes the corresponding autonomic dysfunction.

When the above pathological dominant lesion is limited to one side of the spinal cord, the clinical symptoms appear on the same side of the lesion; if the pathological dominant lesions above the bilateral spinal cord, the above-mentioned clinical symptoms may appear on both sides, but the injured side is still heavy.

Prevention

Reflex somatic neuropathy prevention

There are no better measures, mainly to prevent related diseases that may cause the disease.

Complication

Reflex somatic neuropathy Complications, insomnia

Often irritability, emotional instability, insomnia; pigmentation in the injury site, severe cases may also have bone decalcification and joint space widening; muscle atrophy appears earlier, and can affect the entire limb.

Symptom

Symptoms of Reflex Somatic Neuropathy Common Symptoms Sensory Disorder Muscle Atrophy Pharyngeal Reflex

1. The predilection site: occurs after the sympathetic median nerve and the sacral nerve innervation area are slightly injured.

2. The nerve damage is mild and the symptoms are severe and extensive: such as a slight stab wound on one side (toe), which can cause the lateral and forearm (foot and calf), and even the atrophy and muscle atrophy of the entire limb and contralateral limb. The range of obstacles is wide and far beyond the dominating area of the nerve.

3. Neurological symptoms

(1) autonomic dysfunction: often within half an hour to several hours after injury (generally 2 to 3 hours), there may be obvious autonomic dysfunction mainly characterized by vasomotor dysfunction, often showing limb swelling ( In severe cases, blisters may appear. The complexion is red, purple or marbled, and the skin temperature is lowered. In the later stage, there may be pigmentation of the damaged part and long-term fading, and the nutritional changes of the nail are severe cases. There may also be bone decalcification and widening of the joint space.

(2) dyskinesia: more manifested as severe limb paralysis or contracture, the former mostly appeared in the early post-injury, and more manifested as incomplete (a few are complete) sputum; sputum reflexes are more hyperthyroidism, but also reduce or disappear; The latter appeared later, or changed from sputum, causing dyskinesia, on the one hand due to the reflexive dominant spinal cord lesions, and on the other hand due to the movement pain of the limbs and joints, muscle atrophy appeared earlier And can affect the entire limb, atrophic muscles have increased excitability of mechanical stimulation and DC-induced electrical stimulation, but there is no electrical denaturation reaction.

(3) Sensory disorder: mainly pain, quiet or inactive, pain can be significantly reduced or only mild pain or numbness, objective examination is mostly short-sleeved sensation, a few may have allergies, severe cases may be presented The long sleeve feels diminished and can reach the torso portion near the proximal end of the limb.

Examine

Examination of reflex somatic neuropathy

Blood routine, biochemical examination and routine examination of cerebrospinal fluid are mostly non-specific.

The skull and limb imaging examinations are mostly normal, but they have differential diagnosis.

Diagnosis

Diagnosis and differentiation of reflex somatic neuropathy

1. Patients with obvious autonomic symptoms should pay attention to the identification of diseases such as erythema limb pain, cellulitis, and contact allergic dermatitis.

2. Apparent movement disorders: should pay attention to the identification of peripheral nerve trauma, snoring and other diseases.

3. Pain symptoms are obvious: should pay attention to the identification of diseases such as burning neuralgia, shoulder hand syndrome.
