Getting shoulder range of motion back, in the right order.

Shoulder stiffness shows up in a few very different ways, and they are not treated the same way: frozen shoulder (adhesive capsulitis), which follows its own staged natural history; post-surgical stiffness after rotator cuff repair or stabilization surgery; and the internal rotation deficit that develops in throwers, swimmers, tennis, and volleyball players from repetitive overhead load — glenohumeral internal rotation deficit, or GIRD.

This is educational information, not a personalized program. What your shoulder needs specifically — how far to push range, how fast to progress, what to avoid — depends on which of these patterns is present, your surgeon's protocol if applicable, and what assessment finds. If you've had surgery, your treating surgeon's specific restrictions always take priority over general information here.

For frozen shoulder, work is matched to phase — gentler range-of-motion work and pain management during the freezing phase, more assertive stretching and manual therapy as the condition moves toward thawing. For post-surgical stiffness, range targets are staged against your surgeon's specific protocol and tear-size considerations, following the same criterion-based logic used across rehabilitation more broadly: motion is progressed against markers being met, not simply against days on a calendar.

For GIRD, two specific stretches — the sleeper stretch and the cross-body stretch — have the best evidence behind them. A systematic review of 11 randomized trials covering 514 overhead athletes found both stretches produced meaningful gains in internal rotation and roughly 40% pain reduction over about four weeks, with no clear difference between the two techniques. It's worth being direct about a limitation here too: that same review found stretching alone improved motion and function but did not significantly improve strength or external rotation range — which is exactly why mobility work for GIRD is paired with the strength page below, not used as a stand-alone fix.

One point worth addressing honestly: whether correcting GIRD actually prevents shoulder or elbow injury is not settled science. Some cohort data in pitchers has linked larger internal rotation deficits — roughly 18° or more — to a higher rate of shoulder and elbow injury, and a difference of up to about 15° between arms may simply be a normal, non-pathological adaptation. But a more recent systematic review found that GIRD alone was not clearly associated with upper-extremity injury risk once the wider evidence base was pooled, and the picture is even less clear in adolescent athletes. Restoring internal rotation range has good evidence behind it for reducing tightness and pain — "correcting GIRD prevents injury" is a reasonable goal to work toward, not a guarantee assessment can promise.
