Ulnar Nerve Glide Tool

Interactive Tool

Perform 10 nerve glides, 2x daily. Take 3-5 seconds per position. Stop if symptoms significantly increase — a mild stretch sensation is normal.

What Is Cubital Tunnel Syndrome?

Cubital tunnel syndrome occurs when the ulnar nerve — the nerve responsible for the "funny bone" sensation — becomes compressed or irritated as it passes through the cubital tunnel at the medial (inner) elbow. The ulnar nerve controls sensation to the ring and little fingers and motor control of many intrinsic hand muscles.

Ulnar Nerve Path: From Neck to Pinky

The ulnar nerve originates from the C8-T1 nerve roots in the cervical spine. It travels through the brachial plexus, down the inner arm, through the cubital tunnel at the elbow (the narrowest point), continues down the forearm, and ends at the ring finger and little finger.

Cubital Tunnel vs Carpal Tunnel: Carpal tunnel affects the median nerve at the wrist — tingling in thumb, index, middle, and half the ring finger. Cubital tunnel affects the ulnar nerve at the elbow — tingling in the ring and pinky finger. Location of tingling identifies which nerve and which tunnel.

Common Causes

  • Prolonged elbow flexion — sleeping with elbows bent, holding the phone to your ear
  • Leaning on the elbow — resting elbow on a hard desk surface
  • Repetitive elbow flexion/extension — throwing athletes, weightlifters, workers
  • Anatomical variants — a shallow cubital tunnel or a subluxing (snapping) nerve

Ergonomic Workspace Guide

Monitor Height

Top of the monitor should be at eye level. Head forward and down forces sustained neck flexion that tensions the ulnar nerve from its origin. A monitor arm makes adjustment easy.

Elbow Position

Elbows should be at 90-100 degrees — never sharply bent. Armrests should support the elbow without pressing into the medial epicondyle (the bony inner bump). Use padding if armrests are hard.

Keyboard Placement

Keyboard close enough that elbows remain at your sides. Extended arms increase the angle at the elbow, straining the cubital tunnel. A split keyboard can help maintain a more neutral forearm position.

Nighttime Splinting

Many people unconsciously flex their elbows tightly during sleep, compressing the nerve for hours. A soft elbow splint (or DIY: towel wrapped around elbow) maintains 30-45 degree extension during sleep. Dramatically reduces morning symptoms.
