Heavy movements of the lower extremities, feeling heavy when lifting the foot high up and heavy when landing, are symptoms of sensory ataxic gait. How is this symptom diagnosed? Patients cannot stand with eyes closed, sway and fall easily, vision can be partially compensated when eyes are open (Romberg’s sign); heavy lower limb movements when walking, lifting the foot high and landing heavily, aggravated when walking at night or with eyes closed. Mostly due to obstruction of veins and lymphatic vessels in the lower extremities, resulting in the entry of body fluids into the tissue spaces, into embolic phlebitis of the lower extremities, lymphangitis, filariasis, pelvic or lower extremity tumors compressing the veins. Sensory ataxia gait is more likely with spinal cord lesions, and spinal MRI cerebrospinal fluid examination, electromyography and somatosensory evoked potentials should be selected. Ancillary examinations include: ① cranial CT and cranial MRI scan: it can show cerebellar and brainstem atrophy. ② Pneumoencephalography: increased gas under the subarachnoid space and cerebellar curtain notation is seen, suggesting cerebellar and brainstem atrophy. Sensory ataxic gait is seen in subacute joint degeneration spinal cord pimples hereditary ataxia posterior cord lesion diabetes mellitus and cancerous neuropathy. It is due to degenerative, secondary atrophy of nerve cells and posterior root fibers in the spine can cause the disease, which is autosomal recessive, the onset of which mostly begins in early childhood or adolescence and gradually worsens with age. Correct anemia as soon as possible with vitamin B12 200-500/μg/d, or Micropôle 500μg/2d, intramuscularly, iron supplements if necessary, folic acid, vitamin B1, and other symptomatic treatments. Nursing care: according to general neurology nursing care routine. For paralysis, follow the paralysis care routine. Correct constipation and keep urine and stool unobstructed. Instruct and encourage more B-vitamin-rich foods.
