What is Ulnar Nerve Flossing?

Ulnar Nerve Flossing is a type of nerve mobilization exercise designed to help restore the normal movement and flexibility of the ulnar nerve as it travels through the arm and into the hand. The ulnar nerve runs from the neck (C8–T1 nerve roots) down to the hand, passing through tight spaces like the cubital tunnel near the elbow. When irritated or compressed—commonly known as cubital tunnel syndrome—it can cause tingling, numbness, or weakness in the ring and little fingers.

Nerve flossing, also called nerve gliding, helps reduce this irritation by moving the nerve gently through its surrounding tissues, preventing adhesions and improving blood flow. These exercises are often prescribed by physical therapists or occupational therapists as part of conservative treatment before considering surgery for nerve entrapment. Regular practice can help restore range of motion and decrease symptoms associated with nerve compression.

Exercises

Ulnar nerve flossing exercises involve controlled movements that stretch and glide the nerve along its pathway. A common exercise starts with the arm bent at the elbow and the wrist extended. From there, you gradually move between positions that lengthen and shorten the nerve path without overstretching it. Movements are slow and deliberate to prevent irritation.

One example is the “OK sign position” exercise:

• Start by holding your arm out to the side with your elbow bent and palm facing your face (as if making an “OK” gesture).
• Extend your fingers and wrist while tilting your head away from your arm to tension the nerve.
• Return to the start position and repeat 8–10 times.

Additional variations may involve shoulder abduction, elbow flexion/extension, or wrist and finger positioning to progressively mobilize the nerve through the cubital tunnel and Guyon’s canal at the wrist.

Technique

The technique for ulnar nerve flossing focuses on alternating tension and relaxation in a smooth, rhythmic motion. It’s important not to stretch aggressively, as nerves are sensitive structures that can become inflamed if overstressed. The goal is to create a gentle gliding motion that encourages mobility rather than an intense stretch.

During the exercise, patients should maintain good posture, avoid shoulder elevation, and keep movements pain-free. Using a mirror or working under supervision initially ensures proper form. In more advanced cases, therapists may modify the technique by including neck or shoulder movements to improve nerve mobility through the cervical and thoracic regions as well.

Benefits

Ulnar nerve flossing offers multiple benefits for individuals suffering from nerve entrapment or mild neuropathy. It helps decrease compression on the nerve, reduce tingling or numbness, and improve muscle coordination in the hand. Enhanced nerve mobility can also prevent scar tissue formation after injury or surgery and promote healthier nerve function.

In addition to symptom relief, nerve flossing improves flexibility and functional range of motion in the upper extremity. Regular exercises can also enhance circulation to the nerve and surrounding tissues, reducing inflammation. For athletes, desk workers, or anyone prone to repetitive strain injuries, incorporating these exercises can serve as a preventive measure against developing chronic ulnar nerve irritation.

Procedure

A basic procedure for ulnar nerve flossing is as follows:

1. Sit or stand upright with shoulders relaxed.
2. Abduct your arm (move it out to the side) to shoulder level and bend your elbow to 90 degrees.
3. Bring your fingers up as if holding a tray, palm facing upward.
4. Extend your wrist and fingers outward while slowly tilting your head away from your hand to add gentle tension.
5. Then relax by returning your head to neutral and flexing your wrist slightly.

Repeat this gliding motion slowly for 8–12 repetitions, once or twice daily. If tingling, pain, or increased numbness occurs, stop the exercise and consult a healthcare provider. These exercises should never cause sharp pain. When performed correctly, they can gradually improve mobility and alleviate symptoms of ulnar nerve entrapment.
