Doctor, why can’t my feet hook up?

Case 01

Xiaoyan is a thin girl in her twenties.

Because “the left foot is difficult to lift 10 days” came to the hospital for treatment.

When Xiaoyan stood quietly at the door of the electrochemical room, she couldn’t see any abnormalities. But when she walked, her left foot was a bit strange, as if she had been crossing the threshold and let her do her foot, we found that her left foot could not hook up.

Results The two lower limb electroorphoscope examination reminders: The left side of the left gangsal nerve fibula is lested on the lower part of the fibula small head. Sure enough, the results of ultrasonic examinations confirmed that the general nerves were thickened and edema at the small fibula.

In the end, Xiaoyan diagnosed the disease of the left gaps in the left gap, and the symptoms improved after the treatment of nutritional nerve treatment. After 4 months, the syndrome of the left side of the electrocardiopathy was returned to normal.

Case 02

Wang Shu, sixty -year -old, has been in his left leg for more than 4 months. At first, he didn’t feel that there was any big problem, so he didn’t take it to heart, but recently Wang Shu felt that his left leg was weak, and sometimes walking would trip over. , Hurry up to the hospital to see a doctor. We can obviously see that when he walks across the threshold gait. Like Xiaoyan, Uncle Wang’s left foot cannot do hooking movements, and the muscles outside the left calf have shrunk.

When making a double -limb muscle electrocardiogram for Uncle Wang, we found that the total volatility of his macroeter nerve on the left side was very low. After a series of detailed examinations, Uncle Wang’s examination results indicated that the left waist 5 nerve root disease was destructive. The total neuropathy was severely damaged, and Uncle Wang’s lumbar magnetic resonance examination was just confirmed.

For this performance of Uncle Wang and Xiaoyan’s foot,

Medical is called “foot droop”.

Foot drooping refers to the weakness of the ankle joints (in general, that is, the power that cannot be hooked or hooks), often accompanied by the weakness of toe stretching and turning the feet. The foot raising and the tip of the foot first landed, as if crossing a threshold, that is, “cross -threshold gait”, some patients may have sensory disorders on the outside of the calf and the back of the feet.

Cross -threshold gait -Drag the affected feet when walking or raising the affected feet, landing on the tip first

It is also impossible to hook up, why is the causes different?

From the perspective of anatomical structure, the nerves and muscles of the human body are like a big tree. There are many branches on the stout trunk, like nerves, and many leaves are born on various branches. muscle. Seemingly an inconspicuous movement, in fact, multiple structures in the body are participating. There is a problem with any link in this structure, and the action cannot be completed smoothly.

Generally speaking, drooping is caused by weakness or paralysis of the muscles of the hook, and muscles (leaves) participating in the hook movement are mainly dominated by the macular nerve (branches). The anterior corner cells (trunk) in the spinal cord form the nerve root. After leaving the spinal canal, it participates in forming the lumbosacral nerve clue (tree salamander). These nerve fibers enter the outer branches of the sciatic nerve and form a macular nerve (branches) in the route nest. In addition, the human brain played a very important role in the whole process as an instruction official. Therefore, all the nerve structure that affects the dorsal extension of the ankle joints, from the brain, spinal, nerve roots, lumbosacral nerve clues to sciatic nerve and macular nerve damage, can cause drooping foot.

Note: The picture on the right is a brief diagram, which does not fully represent the anatomical structure of the human body. It is only convenient for readers to understand.

What should I do if I find that my feet are drooping?

1. First go to the hospital in time to consult a professional doctor.

2. Make necessary inspections.

The cause of accurate identification of sagging is often difficult, and detailed medical history collection and nervous system check should be performed. And with the help of the corresponding auxiliary examination, such as neuroelectronic examination. In addition, imaging examinations such as ultrasound and magnetic resonance also have important diagnostic value. Comprehensive examination helps the clear diagnosis of the lesion, select the appropriate treatment method and predict the prognosis.

3. Listen to the doctor’s guidance and receive targeted treatment (nutritional nerves, feet warm therapy, rehabilitation exercise, acupuncture and massage, wearing branches, surgery, etc.).

Why do neuropsychological examinations?

05

Generally speaking, neuropsychological examinations include neurotripping speed measurement and needle electrode muscle electromycardia (we generally referred to as muscle images, such as the lower limb muscle electrocomputer mentioned in the case). In addition, some patients can also induce electrical physiological examinations such as power -induced power generation, motion -induced potential, F wave, and H reflection to clear the diagnosis.

We just used a large tree to simplify the anatomical structure of the hook action. These structures have their own characteristics and have very important positioning diagnostic value. And in the early stage of damage, neuropsychological examination can be found in neurological damage, which is of great significance to doctors formulating treatment plans and assessing patient prognosis of patients.
