Brown-Séquard syndrome (also known as Brown-Séquard's hemiplegia, Brown-Séquard's paralysis, hemiparaplegic syndrome, hemiplegia et hemiparaplegia spinalis, or spinal hemiparaplegia) is caused by damage to one half of the spinal cord, i.e. hemisection of the spinal cord resulting in paralysis and loss of proprioception on the same (or ipsilateral) side as the injury or lesion, and loss of ...
Central cord syndrome, almost always resulting from damage to the cervical spinal cord, is characterized by weakness in the arms with relative sparing of the legs, and spared sensation in regions served by the sacral segments. [25] There is loss of sensation of pain, temperature, light touch, and pressure below the level of injury. [26]
Dissociated sensory loss is a pattern of neurological damage caused by a lesion to a single tract in the spinal cord which involves preservation of fine touch and proprioception with selective loss of pain and temperature. Understanding the mechanisms behind these selective lesions requires a brief discussion of the anatomy involved.
Here you can see a typical test where the first lactate threshold is at around 210-215 power output and their second lactate threshold is at 260-265.
Those with femoral nerve dysfunction may present problems of difficulties in movement and a loss of sensation. [medical citation needed] The patient, in terms of motor skills, may have problems such as quadriceps wasting, loss of knee extension and a lesser extent of hip flexion given the femoral nerve involvement of the iliacus and pectineus muscles.

The damage may result in loss of feeling, paralysis, weakness, [4] and stiffness in the back, shoulders, and extremities. Syringomyelia may also cause a loss of the ability to feel extremes of hot or cold, especially in the hands. It may also lead to a cape-like bilateral loss of pain and temperature sensation along the upper chest and arms.
[12] [26] Muscle necrosis can happen fast, sometimes within just 3 hours after an injury. [13] A fasciotomy in the leg's lateral compartment might cause symptoms affecting nearby nerves and muscles. [10] These may include foot drop, numbness along leg, numbness of big toe, pain, and loss of foot eversion. [10]
This syndrome is characterized by sensory deficits that affect the trunk and extremities contralaterally (opposite to the lesion), and sensory deficits of the face and cranial nerves ipsilaterally (same side as the lesion). Specifically a loss of pain and temperature sensation if the lateral spinothalamic tract is involved. The cross body ...
