An upper limb neurological examination is part of the neurological examination, and is used to assess the motor and sensory neurons which supply the upper limbs. This assessment helps to detect any impairment of the nervous system, being used both as a screening and an investigative tool.
A neurological examination is the assessment of sensory neuron and motor responses, especially reflexes, to determine whether the nervous system is impaired. This typically includes a physical examination and a review of the patient's medical history , [ 1 ] but not deeper investigation such as neuroimaging .
The three nerves that control the extraocular muscles are the oculomotor nerve (CN III), the trochlear nerve (CN IV), and the abducens nerve (CN VI). As the name suggests, the abducens nerve is responsible for abducting the eye, which it controls through contraction of the lateral rectus muscle.
The spinal nerves arise from the spinal column. The top section of the spine is the cervical section, which contains nerves that innervate muscles of the head, neck and thoracic cavity, as well as transmit sensory information to the CNS. The cervical spine section contains seven vertebrae, C-1 through C-7, and eight nerve pairs, C-1 through C-8.
Symptoms can also worsen while the patient is walking or during periods of increased stress. Other symptoms include muscle hypertrophy, neck pain, dysarthria and tremor. [2] Studies have shown that over 75% of patients report neck pain, [1] and 33% to 40% experience tremor of the head. [3]
The function of this muscle is to rotate the head to the opposite side or obliquely rotate the head. [4] It also flexes the neck. [4] When both sides of the muscle act together, it flexes the neck and extends the head. When one side acts alone, it causes the head to rotate to the opposite side and flexes laterally to the same side (ipsilaterally).
Occlusion of blood vessels that supply the nerves or their nuclei, an ischemic stroke, may cause specific signs and symptoms relating to the damaged area. If there is a stroke of the midbrain, pons or medulla, various cranial nerves may be damaged, resulting in dysfunction and symptoms of a number of different syndromes. [26]
Differentiation of the cause of Wartenberg's sign is based on associated clinical findings in the history and examination and sometimes involves investigations including radiographs and/or MRI of the cervical spine, elbow/wrist/hand and/or nerve conduction studies and EMG. [citation needed]
