The Claim

Real-time electromyography (EMG) biofeedback intervention is associated with decreased posterior deltoid muscle activity during seated shoulder external rotation exercise in adults with round shoulder posture, resulting in reduced unwanted muscle coactivation.

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.

Cause and effect
1 study reviewed
In plain English

When adults with rounded shoulders use a device that shows them their muscle activity in real-time while doing a shoulder rotation exercise, it helps them reduce overactive muscles in the back of the shoulder that cause problems.

  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 showed that when people with round shoulder posture used real-time EMG biofeedback during their shoulder exercise, the posterior deltoid muscle became less active - exactly what the claim says. This confirms the claim is accurate.
