The Claim

Real-time EMG biofeedback is associated with an increased infraspinatus-to-posterior deltoid activation ratio during shoulder external rotation in adults with round shoulder posture, indicating improved muscle balance.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Supports
34score
Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Using a machine that shows muscle activity in real-time while doing shoulder exercises helps people with rounded shoulders activate their back shoulder muscle more than the back part of their shoulder muscle, which is a good thing for shoulder health.

What the research says

1 study

  1. Study: Effect of Real-Time EMG Biofeedback on Selective Activation of the Infraspinatus and Posterior Deltoid During Theraband Shoulder External Rotation Exercise in Individuals with Round Shoulder Posture

    The study shows that using real-time EMG biofeedback during shoulder exercises helped people with round shoulder posture activate their infraspinatus muscle more and their posterior deltoid muscle less, which improves muscle balance - exactly what the claim states.
