Treatment of scalene muscles with the Ergon technique can lead to greater improvement in hip abduction range of motion than local hip adductor treatment: a study on deep front line connectivity.

PMID 33281284WHAT IT FOUND
In healthy adults with tight hip adductors, one 15-minute Ergon IASTM session increased hip abduction immediately.
Treating neck scalenes produced greater gains than local hip adductor treatment.
Key findings
01Both remote scalene treatment and local hip adductor treatment significantly improved hip abduction range of motion on the treated side, while the untreated control side did not change significantly.
02Remote scalene treatment produced significantly greater improvement than local hip adductor treatment for active hip abduction at 0° and 90° and passive hip abduction at 90°.
03There was no significant difference between the two treatments for passive hip abduction at 0°.

What it does not show
Only healthy adults with decreased hip adductor flexibility were studied, so the results may not apply to people with pain, injury, or clinical stiffness. The effect was measured only immediately after one 15-minute treatment, so the study does not show how long any change lasts. The study was not blinded, and hip motion was measured with a goniometer rather than a more precise tool. The sample was small, and each person acted as their own control with the untreated opposite hip.
Declared interests
No conflicts of interest were declared.
The easy way to misread this
Do not conclude that treating the neck scalenes is a proven way to improve hip motion in patients. This was a small study in healthy adults, measured only immediately after treatment, and it did not show how long the change lasts.
