Why not ? I mean resisted or prolonged shoulder elevation would activate and strengten the specifics muscles that elevate shoulder girdle, this would make a permanent release effect at time, or preventing compression, no ?

Some recommend it for TOS, others don't. I've done shoulder shrugs intermittently in my workouts.its difficult to isolate the levator scapulae and upper trapezius without feeling some anterior neck muscle involvement as you perform the exercise. Especially the SCM muscle which may not be a good muscle to strengthen in TOS

Unfortunnaly, i agree.

And some have atrophy, but some have hypertrophy.

here a study : http://www.silcom.com/~dwsmith/ajs293.html

Any experience about it ? For those who got tos with droopy shoulders.

im SLOWLY doing this bc my exact problem is droopyness. i have a long wingspan, long thin neck. not overdeveloped muscles like some. my problem is instability of on my neck (givin myself whiplash unintentionally) and my shoulders. ive never dislocated anything but the way i move my body all day long is straight up abuse.

shoulder shrugs are a bad idea bc the tissues around are all irritated, right? you dont want to encourage more inflamation

what im doing at home now are very very simple "activation" type exercises. so for one exercise i have two pillows under my arms and i sit with my tailbone tucked in and squeeze my shoulders together for 5 seconds to activate my lower shoulder muscles. initially my gut said to do it using my upper traps and neck! but after awhile you start to learn what feels right vs. wrong.

but my problem is droopyness for those of you with hypertrophy and severe muscle spasms im not sure

oh and i should add so far i really like these exercises. i feel a little burn sometimes but it's contained to the muscle aka good burn. im trying this stuff called gyrotonics in physical therapy. ill let you guys know if i have any luck.

also i guess ishould add one of my shoulders is a lot droopier than the other. it gets tired more easily and i avoid using that arm yet both sets of hands are completely numb. maybe i would be able to feel my hands on the less droopy side but that side also has the elevated rib. im curious if i get sensation back in both hands at the same time or not.

i think actually theres a big difference between neural fatigue, nerves being stretched out, this is mostly what i have. i have it on my droopier side but its not painful. its just tired and cold. vs. actual pain caused by tightness and spasms. whole different ball park.

Where are the exercises for that study? The paper seems kind of sloppy for not describing them and the regimen (order, reps, sets, workout frequency, etc.).

Well actually the original paper does have them, but not the copy there. Does anyone have "Table I" and "Figure 1" for this paper?
