As discussed previously, s ubluxation may be present in some patients during the rehabilitation phase of stroke because overactivity in the trapezius is creating glenohumeral separation.
Weights are often used, either in the hand or as a bar braced across the trapezius muscle or rear deltoid muscle in the upper back.
The muscles that perform this function are the rhomboids and the trapezius.
The narrower the grip the more the trapezius muscles are exercised, as opposed to the deltoids.
It then passes through the trapezius muscle and ascends to innervate the skin along the posterior part of the scalp to the vertex.
Since it is a muscle of the upper limb, the trapezius is not innervated by dorsal rami despite being placed superficially in the back.
It starts at the midline of the occiput and connects to the upper trapezius.
It is deep to the trapezius, and is located directly inferior to the rhomboid minor.
