If you have either tendonitis or carpal tunnel syndrome then you should check out ART (Active release techniques) developed by Dr. P. Michael Leahy. ART is a patented method to deal with carpal tunnel syndrome, tendonitis, tennis elbow and any other type of repetitive motion injury.
What is ART exactly you may ask? ART is a patented, state of the art soft tissue system/movement based massage technique that treats problems with muscles, tendons, ligaments, fascia and nerves. Headaches, back pain, carpal tunnel syndrome, shin splints, shoulder pain, sciatica, plantar fasciitis, knee problems, and tennis elbow are just a few of the many conditions that can be resolved quickly and permanently with ART. These conditions all have one important thing in common: they are often a result of overused muscles.
You can only be treated by an ART provider from the list on the Active Release Techniques website which is often a chiropractor. I had some hand issues in the past as well as a few arm and shoulder issues. I found an ART provider from the website a few miles from my house and after a single treatment I noticed a dramatic improvement. I have also recommended ART to other guitar players (some athletes too) and everyone agreed that ART was surprisingly effective.
If you are dealing with any sort of hand, finger or arm issue that is preventing you from playing at your best then click on the link below and find a provider. It is very effective and is about the cost of a chiropractic adjustment. ART is worth a shot especially if you are considering something as drastic as surgery.
