Rest is recommended to avoid movement that causes pain. A wrist brace or splint is used to reduce movement in the forearm. Wear a wrist or an elbow splint to reduce movement and irritation in the radial nerve.
Apply ice for 10-15 minutes every 2 to 3 hours, it helps to decrease the swelling. It causes vasoconstriction of the blood flow, relaxation and makes the muscles more flexible.
Ultrasound therapy is given to decrease pain and increase circulation.
Manipulation and massage, are given to the soft tissues to prevent the development of adhesions, thus restricting the nerve. Mobility of the nerve reduces nerve entrapment.
Strengthening exercises of the muscles help to maintain the balance between agonist and antagonist muscles, closed-kinetic chain activities, proprioceptive neuromuscular facilitation (PNF) diagonal strengthening patterns, and a full range of motions with protective strength, drills, and plyometrics are recommended.
Wrist Extension Stretch:
Place the affected arm straight in front, with the hand up and fingers facing towards the sky. Use another hand to pull back on the fingers, until a stretch is felt in the forearm.
Wrist Flexion Stretch:
Place the affected arm straight in front, with the hand down and the fingers facing towards the ground. Use the other hand to pull back on the back of the palm until a stretch is felt in the forearm.
Place the affected arm by the side at 90-degree, with the forearm and hand facing up. Put the other hand on the wrist and rotate the forearm inward, toward the body, without moving the other parts of the arm.
Self-directed nerve gliding Exercises:
Radial nerve glides:
Stand straight, drop the shoulders slightly and rotate the arms into the body. Flex the wrist on one side and raise the arm up to waist level as the head is tilted to the opposite way. Once the stretch is felt, hold the position for 5 seconds.
These exercises should be done on both sides, even though dealing with radial tunnel syndrome in one arm.
