Function Test: Is Your Masalo Cuff Fitted Correctly?
With a full 1.5-litre plastic bottle, you can check in just a few minutes whether the Masalo Cuff is fitted correctly for tennis elbow. To do this, you compare lifting the bottle without and with the cuff.

Key points at a glance
- Bottle test: compare lifting without and with the cuff.
- Intended for tennis elbow, not for golfer's elbow.
- Set the upper-arm strap a little tighter for the test.
- No noticeable difference? Then check the fit, adjustment and size.
- Hand test: get a feel for the counter-traction even without the cuff.
Who is the bottle test intended for?
The test is intended for lateral epicondylitis, i.e. tennis elbow. It is not suitable for golfer's elbow – although in that case, with the cuff fitted correctly, you should at least clearly notice the relief.
How to do the bottle test
Lift without the cuff
Take the cuff off. Lift a full 1.5-litre plastic bottle with your arm straight. This typically triggers the familiar pain under strain – stop if the pain is severe.

Put on the cuff and set it tighter
Put on the cuff as described in the instructions and set the upper-arm strap a little tighter for the test. You can loosen it again at any time afterwards.

Straighten your arm against the counter-traction
Straighten your arm with full force against the resistance of the cuff. A bulge appears between the forearm cuff and the elbow.

Lift the bottle again
Lift the bottle once more with your arm straight and compare this with your first attempt.

How do I interpret the result?
If the cuff is fitted correctly, lifting should put noticeably less strain on your arm than without the cuff. If you do not notice any difference, check these points:
- Is the forearm cuff positioned halfway between the hand and the elbow?
- Does the upper-arm strap fit snugly just above the elbow?
- Can you only straighten your arm with some effort?
- Is the size right? It is measured at the widest point of the affected forearm.

Hand test: feel the counter-traction without the cuff
You can also get a feel for the cuff's principle before buying. Here's how:
Grip the forearm
With the hand of your healthy arm, grip the affected forearm exactly in the middle.
Pull the tissue towards the elbow
Pull the tissue firmly towards the elbow.
Straighten your arm and put a little strain on it
Hold the pull while straightening your arm and putting a little strain on it.
If you feel slight relief, this corresponds to the counter-traction that the Masalo Cuff also works with. Find out more on our page about how it works.
