PNMT Super Sleuth
The answer to this scenario is that this client has neural inflammation in their left brachial plexus and the median nerve. In this condition, the nerve is stretched when the arm is fully extended. It is also stretched when the head is fully erect. Nerves do not like to be stretched, especially ones that already sensitized. To put slack in the nerve, the client has figured out that they can do that with lateral flexion of the neck or slight elbow flexion.
In a case like this, to "correct" their posture would be disastrous. Nerves do not like to be stretched. After you treat the nerve, the postural defects will correct themselves.
Most importantly, what is good for a muscle is disastrous for a nerve. You must know which one you are dealing with.
