Dear friends,
Thanks for the response to my query regarding effect of
shoulder movements on the brachial plexus.All the replies were regarding
add/ abd, ext and int rotation only .
Can someone tell us shoulder retraction and protraction
effect on the brachial plexus .I have found many patients not only have
depressed shoulder but protracted shoulder on the symptomatic side ,when we
put our hand under such shoulder i.e scapulae of prone patient and ask the
patient to press initiating an isometric contraction we find very poor and
weak pressure compared to the other asymptomatic side.
This is what our friend Owen Moore calls a DRA syndrome.I
strongly feel there is something missing in understanding of this
manifestation.What I am doing here is just ask these patient to do shoulder
elevation and retraction exercises and it works is most of cases .What I
wish to to learn is about pathogenesis of this positional fault.
Few suggestions to be considered are
1.Postural
2.Neural compression at cervical spine leading to reduced axonplasmic flow
and resulting in hypotonicity of the muscles supplied by that particular
roots.
Any useful information and personal
experiences by the learned friends on the list will be truly appreciated.
