It takes two minutes, requires no equipment, and tells you more about your next twelve months on court than any MRI.
Most tennis and pickleball injuries don't announce themselves. They build.
The shoulder that finally gives out during a third-set tiebreak has usually been losing range of motion for six to eighteen months before the player notices anything. By the time it hurts enough to do something about it, you're looking at six to twelve weeks off the court — and that's the optimistic timeline.
There's a simple test that catches it early. We use it at Stryde with every player over forty-five who comes in for a performance assessment. It takes two minutes. It doesn't require equipment. And if you do it weekly, it tells you almost everything you need to know about whether your shoulder is going to hold up.
The test: combined elevation
Stand with your back against a wall, heels six inches from the baseboard. Press your lower back flat against the wall — not arched, not slumped. Now raise both arms overhead, keeping your thumbs pointing back behind you. Your goal is to touch the wall above your head with the backs of your hands, while keeping your lower back flat.
That's it. That's the test.
If you can touch the wall with both hands flat against it, while maintaining a flat lower back, your shoulder mobility is in good shape for racquet sports. If one or both arms can't reach the wall — or if you have to arch your back to get there — you have a meaningful restriction.
The reason this matters: every overhead shot you hit, every serve, every overhead in pickleball, every smash, requires your shoulder to reach full overhead position with your spine stable underneath it. If your shoulder can't get there cleanly, your body finds the range somewhere else — usually by arching the lower back. Over months and years, that compensation breaks down both the shoulder and the spine.

What restricted means
The most common pattern we see in players over forty-five is this: the dominant arm can reach the wall, but only by arching the back. The non-dominant arm often can't reach the wall at all. Both findings matter.
The arching pattern means your shoulder has lost true overhead range and is borrowing from your spine to fake it. Every serve is now putting load on your lumbar discs that your serve was never supposed to put on them. This is why so many players over fifty develop both shoulder pain and low back pain — they're not coincidences, they're the same compensation pattern showing up in two places.
The asymmetry between arms tells you something else: the dominant shoulder has adapted to your sport, often in ways that include some loss of range as the joint thickens to handle decades of overhead loading. That's normal up to a point, but when the difference becomes pronounced, the joint is being protected by stiffness rather than strength.
What to do if you fail the test
The temptation is to start stretching the shoulder aggressively. That's usually the wrong move. Most failed combined-elevation tests aren't a shoulder problem — they're a thoracic spine problem.
The thoracic spine — the section behind your ribs — has to extend for the arms to clear overhead properly. If it's locked in flexion (the default position from sitting and screens), the shoulders can't reach the wall no matter how flexible they are individually.
So the fix usually starts upstream. Daily thoracic extension work on a foam roller. Wall-supported rotations. Open-book stretches in side-lying. Five to ten minutes, daily. Most players see meaningful improvement on the test within three to four weeks.
If you've done six weeks of thoracic work and the test still fails, then you're looking at a true shoulder restriction — usually capsular tightness or a rotator cuff that's lost the strength to control end-range motion. At that point, an in-person assessment is warranted.
Why weekly
The reason we ask players over forty-five to do this test weekly isn't that mobility changes that fast. It's that small losses are easier to catch and easier to reverse than large ones. A player who notices "I couldn't quite touch the wall this week" can address it with five minutes a day of mobility work. A player who waits until the shoulder hurts is looking at months of rehab.
Think of it as the same logic as checking tire pressure. The point isn't that the pressure changes dramatically week to week. The point is that the cost of catching a slow leak early is essentially zero, and the cost of catching it late is a blowout on the highway.
The shoulder works the same way. The blowout is the third-set tiebreak.
If you've failed this test and want to know exactly where the restriction is — thoracic, capsular, or muscular — schedule a consultation. We can pinpoint it in about thirty minutes and build a protocol that addresses the actual cause, not the symptom.
