While this thought process is common, especially in the general population, it doesn't actually hold much validity. Posture isn't causative of pain and shouldn't be vilified (this doesn't mean you can't modify symptoms by changing positions or postures, rather just because you can change something doesn't mean that it was the cause of the issue to begin with [post hoc ero propter hoc fallacy]). It definitely isn't causative of impingement, and impingement (as a pathoanatomical diagnosis) does not exist.
