Design outcomes

Primary

Measure	Time frame
Ultrasound appearance of 1. Nerve roots: C4 to T1 nerve roots will be visualized longitudinally to evaluate continuity with the spinal cord and aspect of the nerves and surrounding tissue. 2. Brachial plexus: The brachial plexus will be visualized transverse at 3 levels: cervical, supraclavicular and infraclavicula. Continuity, aspect of the nerve and surrounding tissue, visibility of internal structures, and cross-sectional area will be evaluated. 3. Peripheral nerves: Transverse images of the medial nerve at the wrist and ulnar nerve just ditally from the elbow will be made to evaluate the diameter, cross sectional area and visibility of internal structures. 4. Muscle ultrasound of C4 to T1 innervated muscles (measurement of muscle echo intensity and muscle thickness): a. Infraspinatus (C4-C6) b. Deltoid (C5-C6) c. Biceps brachii (C5-C6) d. Triceps (C6-C8) e. Extensor digitorum communis (C6-C8) f. Flexor digitorum superficialis (C7-C8) g. Adductor digitorum brevis (C8-T1)	—
