Picking a Carpal Tunnel Syndrome Splint

Tips for Picking a Carpal Tunnel Syndrome Splint

Did you know that wearing the wrong carpal tunnel syndrome splint can make your condition worse? It's because most splints sold in pharmacies are actually not designed for carpal tunnel syndrome at all.


Here's how you can tell if you're wearing the wrong splint for carpal tunnel:


1) You wake up in the morning and your carpal tunnel symptoms (e.g., finger or hand pain, numbness, tingling) are worse than when you went to bed, or


2) You've been splinting for weeks (or more) and symptoms have not resolved.

If these happen to you, then it's likely your splint is the culprit. But a proper carpal tunnel syndrome splint will probably resolve your symptoms.


Read below about "certified" carpal tunnel syndrome splints. Just as important, see the list of splints you should avoid.




Be certain you have carpal tunnel syndrome

Before you buy a carpal tunnel syndrome splint, be sure you have this disorder to begin with. The symptoms of carpal tunnel syndrome concentrate in the fingers (except the pinky finger) and palm. They are:


  • Pain (usually in the palm, thumb or first fingers)
  • Numbness (usually in the first 3 fingers)
  • Tingling
  • Burning
  • Shooting electric shocks
  • Weakness
  • Clumsiness

When the disorder begins, symptoms typically show up while resting or trying to sleep. Actually, if symptoms are worse while using your hands, it's usually due to tendonitis and NOT carpal tunnel syndrome.


Do the above symptoms match what you're feeling? You can double check by taking this FREE self-test to see if you have carpal tunnel syndrome or another disorder (like tendonitis).


If you do indeed have carpal tunnel, then wearing a certified carpal tunnel syndrome splint is a good first step toward eliminating the problem.

Important Note:

If the intensity of your symptoms are moderate or severe OR have persisted for more than 1 year, it means you have advanced carpal tunnel syndrome. In such cases a splint alone may not be enough to reverse your symptoms. See below for more information.

How & when to wear a carpal tunnel syndrome splint

Carpal tunnel syndrome isn't a disorder like arthritis or a fractured wrist. It's a specific condition with specific splinting requirements. Here are the 2 things to know.

1) Only a certified carpal tunnel syndrome splint will help

A certified carpal tunnel syndrome splint means it's designed to treat carpal tunnel - and nothing else. They are examined and approved by orthopedic doctors to use with carpal tunnel syndrome. They are not designed for sprains, arthritis, etc.


Certified carpal tunnel syndrome splints are called "specialty medical products". In other words, you cannot find them in drug stores like Walgreens, CVS, Rite Aid or Walmart. They can only be purchased from approved online suppliers - listed below.

What's a "certified" carpal tunnel syndrome wrist splint?


  • A certified splint does not have a palmar spine (a flat metal bar on the splint's palm surface). Such a spine pushes into  your carpal tunnel space, further compressing your median nerve.
  • A certified splint contains 1 or 2 "lateral" or "dorsal" metal stabilizers instead of a palmar spine.

2) Splint your wrist at night but not during the day

Nocturnal splinting is great for mild or early moderate stage carpal tunnel syndrome. But you must not wear a wrist splint when your hand is working during the day.


That's because carpal tunnel syndrome has already begun. It means the flexor tendons in your forearm are stressed and swollen. This swelling is what causes pressure on the median nerve in your wrist. That pressure is what causes all of the symptoms of carpal tunnel syndrome.


So why add more stress to your wrist tendons? A splint will cause your hand to fight the restriction while you perform your daily manual duties. This adds additional strain to your already stressed tissues, making carpal tunnel symptoms much worse.


So don't wear a splint during the daytime if you have carpal tunnel!

The problem with drugstore splints


A splint on the shelf at CVS, Walmart, Rite Aid, or Walgreens might claim it's good for practically everything, including carpal tunnel syndrome. But this cannot be true.


Actually, no splint on earth can treat all conditions, from sprains to arthritis to carpal tunnel. It's just not possible. It's like having one tire model for every car.


Drug store splints are not doctor-certified for use in carpal tunnel syndrome. Drug stores simply don't carry these specialty medical products due to lower demand.

Avoid these splints

These are the most popular splints sold today. Not a single one is a certified carpal tunnel syndrome splint. So avoid them at all costs!

Summary

Wearing a certified carpal tunnel syndrome splint while you sleep is a great first-line treatment for this disorder. But if your carpal tunnel is more advanced or severe, then night splinting alone may not be enough to help reverse symptoms.


In that case, you will likely require more aggressive therapies in addition to night splinting. These include daily hand and finger stretching exercises and myofascial release massage for a period of 6-8 weeks.
