Wednesday Rehab – Iso-integrating Serratus in Scaption

Our challenge as we progress with Serratus Anterior work is to engage it towards upward rotation (which seems harder than protraction for most people). Working from horizontal arm protraction like the Serratus Plank last week, to raising it overhead can be very tricky for those with Impingement Syndromes of many varieties.

“Iso-Integration” initially involves trialing whether using theratubing pulling backwards as a static tension removes their pain they otherwise would have with shoulder press. Why could adding tubing work? Due to its ability to activate “Subscapularis” (the magic shoulder stability muscle), which in turn works with Serratus to help improve upward rotation.


  • Position arm in “Scaption” (see bottom of page) to begin with, as that gives us the best chance of success with the sore shoulder.
  • Keep the elbow bent to 90 degrees with forearms vertical;
  • Test the movement without any tubing first to see client’s pain level;
  • Then add the tubing or use the swiss ball (see the video), and assess if their pain is gone or near it. It happens regularly for people!


If the pain is gone from the Shoulder Press movement with the Iso-Integration added, then this functional movement becomes a “Rehab Movement” for improved activation of Serratus Anterior and Subscapularis. Do 30-40 Reps twice a day for 2 weeks, aiming for new neural pathways to be laid down. Keep testing if pain is reduced without the theratubing.


Rehab Trainer has developed a multitude of signature Iso-Integration drills for use all around the body to try and reduce pain – this one remains our most tricky to perform, so you have to do it carefully to get best results.

Alright hope the video helps to make all of this complexity a little less confusing or muddy.


What is Scaption anyway? Also, called “Scapular Plane”, it’s the commonly ascribed angle of 30 degrees forward of the body’s Frontal Plane, where the Scapula sits most naturally for the average person.





How to Feel it? Put your arms out to the side in line with your trunk like you are going to do a lateral shoulder press. Then bring your elbows forward so your forearms just come into view, and you will be pretty close.
