Where your shoulder hurts doesn’t tell us which part of it is injured.
The four rotator cuff muscles, the biceps tendon and the joint itself all sit in a tight space and tend to send pain to the same area, usually the front or outside of the upper arm. Pointing at the sore spot narrows things down far less than people expect.
So the assessment works by ruling things out one layer at a time. Watching you lift your arm first shows what the shoulder does on its own, before anyone has touched it.
Next we move your arm for you while you relax. If it moves freely that way but hurts when you lift it yourself, the problem’s likely in a muscle or tendon. If it’s stiff either way, we look harder at the joint and the tissue around it.
Then each strength test loads one part at a time. We’re looking for pain and for weakness, and they don’t always turn up together. A tendon can be sore and still strong, or test weak simply because it hurts to push.
The labrum and instability checks come last because those problems are less common, but when they’re positive they change the plan more than anything else. A shoulder that’s slipped out before needs a very different approach to an irritated tendon.
That’s how two people pointing at the same sore spot can leave with completely different programs. It’s also why the testing happens at the start of every appointment, before any hands-on work.
If your shoulder’s been grumbling for more than a few weeks, book in through the link in our bio and we’ll work out which part it is.
