Title says it all. Inoperable full-thickness tear of the left supraspinatus with significant retraction. Because of the tear, I have significant left shoulder instability and have to spotter-less work on a Smith for the most part, and my dumbell work is weight limited. It’s not just weakness/instability, I have to ensure I don’t tear something else. I’ve been wondering whether one of those neoprene shoulder sleeves or some other wearable contraption would stabilize the shoulder and assist with at least heavier dumbell work. Any experience with such things here? Appreciate the advice, and apologies if I posted (again) in the wrong location!
