Banded Posterior Shoulder Capsule Distraction

Tips

• Keep the shoulder blade down and back rather than shrugging up.
• Move gently; the posterior capsule responds to time under low tension, not force.
• Stop if you feel any pinching in the front of the joint and reduce the band pull.

Variations

• Banded Overhead Shoulder Traction
• Cross-Body Shoulder Stretch
• Sleeper Stretch

Common mistakes

• The loop is placed down near the elbow rather than high on the upper arm, so the pull bends the arm across instead of drawing the humeral head away from the socket.
• Standing position leaves the band pulling straight across the chest with no outward component, which gives a cross-body stretch and no distraction.
• The shoulder blade is allowed to ride up toward the ear as the arm comes across, and a shrugged blade lets the whole movement happen at the scapula rather than the joint.
• Force replaces time here: people lean hard into the elbow for a few seconds when the back of the shoulder gives up length slowly under a light, sustained pull.
• A pinch at the front of the joint gets pushed through, when that is the sign the humeral head is being driven forward too far and the band needs slackening.
• Only the stiff overhead side gets the work, so the difference between shoulders widens instead of closing.

Frequently asked

How long should I hold the banded posterior shoulder capsule distraction?

Two or three holds of 30 to 45 seconds per shoulder, breathing slowly throughout, is the working dose. Keep the band light enough that the shoulder can stay relaxed for the whole hold, since this tissue responds to sustained low tension rather than force. It is fine daily, and it fits well before pressing or pulling. Check whether it worked by testing a cross-body reach or internal rotation behind the back before and after, rather than by how hard you can pull.

What can I use instead of a band for the posterior shoulder capsule distraction?

A partner can do it better than a band: they stabilize the shoulder blade with one hand and draw your upper arm out and across with the other. On your own, a sleeper stretch lying on the affected side, or a cross-body stretch with the other hand guiding the elbow, covers the posterior shoulder without any equipment, though neither decompresses the joint. A towel looped around the upper arm and anchored in a closed door gives a rough version of the pull.

What is the banded posterior shoulder capsule distraction good for, and who should avoid it?

A tight posterior capsule takes away internal rotation and cross-body reach, which shows up as a cranky feeling in pressing and pulldowns, and this drill gives that tissue room to release. Throwers, swimmers and desk-bound shoulders are the usual audience. Avoid it after a recent shoulder dislocation or stabilization surgery unless a clinician has cleared traction, and leave it alone if the band produces pain at the front of the joint rather than a stretch at the back, since that is the opposite of what you want.
