Are your patients with shoulder pain not improving as expected?

You already know that subacromial syndrome is one of the most common shoulder conditions and a frequent source of pain. And while clinical diagnosis may seem straightforward, the true cause of the pain often remains hidden.

Many times, pain persists despite treatment, and you might ask yourself: Am I missing something important?

The answer could lie in imbalances within the scapulohumeral synergy, especially between the anterior deltoid, upper trapezius, and lower trapezius. Without analyzing these, you risk applying exercises that don’t fix the problem or even make it worse.

This is where surface electromyography (sEMG) comes in: a tool that shows you clearly how muscles behave during real movement. No more guessing, you can now measure, compare, and intervene with precision.

Imagine being able to see if your patient is overusing the anterior deltoid during arm elevation, or if the lower trapezius is barely active. Now you can, with objective data that sharpens your clinical reasoning.
