The final carpal tunnel stretch should include this forearm exercise. The tendons in the forearm run from the arm muscles, through the carpal tunnel (inside the wrist joint) and into the hand and fingers. That’s a long way for them to go. As a result, it’s also a lot of stretching to do. But this exercise will do it.
First, start by putting both hands in a "praying" position. In other words, put both palms and fingers together, pointing upward. Keep them close to the chest. Then, while maintaining both palms together and at the same level, slowly raise both elbows.
This will stretch tendons throughout the forearm and even to the fingers. Hold this position for 10 seconds and then relax. Let both hands drop at your sides and shake them out vigorously for 5 seconds.
A warm feeling in your fingers and hands means blood is flowing
through them. This exercise also encourages fluid drainage
from the wrist joint. Repeat this carpal tunnel stretch once again.
