The eight bones of your wrist form a U-shaped channel that houses several tendons and your Median nerve. This channel is called the Carpal tunnel. Your median nerve is responsible for sensation on the palm side of your first 3 ½ fingers. Compression or irritation of this nerve as it travels through the carpal tunnel causes the condition known as “Carpal tunnel syndrome”.
Carpal tunnel syndrome can be brought on by prolonged wrist flexion and/or repetitive wrist movements like supermarket scanning, keyboard use, carpentry or assembly line work. Here’s an exercise to help “release” the median nerve.
