What level is the spinal accessory nerve?
What are common causes of dysfunction, what is clinical presentation?
What sensory distribution would be lost?
What motor defecits would you have?
What reflex changes may happen?

Weakness is upper trapezius and SCM
Patients with spinal accessory nerve palsy may exhibit signs of lower motor neuron disease such as diminished muscle mass (atrophy) and fasciculations of the sternocleidomastoid and trapezius muscles.
What level is the long thoracic nerve? What are common causes of dysfunction, what is clinical presentation? What sensory distribution would be lost? What motor defecits would you have? What reflex changes may happen?
Usually, injury to this nerve occurs due to trauma, direct blow to the rib area, over stretching or strenuous repetitive movements of the arms, and sustained bearing of excessive weight over the shoulder. Moreover, surgical procedures such as radical mastectomies and deep tissue massage may even cause long thoracic nerve injury.
The major symptoms associated with long thoracic nerve palsy, include:
Shoulder pain
Winged scapula
Reduced overhead activity
What level is the spinal supra-scapula nerve?
What are common causes of dysfunction, what is clinical presentation?
What sensory distribution would be lost?
What motor defecits would you have?
What reflex changes may happen?
Suprascapular neuropathy is a less common cause of shoulder pain in athletes but is seen particularly in those who participate in overhead activities. Athletes who participate regularly in overhead sports are more susceptible to developing suprascapular neuropathy.
Atrophy of the supraspinatus and/or infraspinatus muscles may be present on the physical examination, depending on the site of the nerve entrapment
Manual muscle testing may reveal relative weakness of ipsilateral shoulder abduction (a function of the supraspinatus muscle in addition to the deltoid muscle) and/or weakness of external rotation
