RSI: Ulnar Nerve Entrapment

Ulnar Nerve Entrapment can cause serious injuries


What causes ulnar nerve entrapment?

Ulnar nerve entrapment is caused by pressure on the ulnar nerve at either the elbow or wrist. The condition often develops in connection with overstraining due to one-sided hand movements during work, or because of powerful and/or awkward working movements for many years. Using a computer mouse for long hours can be a big proponent of developing ulnar nerve entrapment.


  • Weakness or tenderness in the hand
  • Tingling in the palm and fourth and fifth fingers
  • Sensitivity to cold

What we recommend

Centrally located in front of the keyboard, a rollermouse eliminates harmful movements by keeping users arms in a neutral, forward posture. By design a rollermouse will ensure users reduce pressure on the ulnar nerve in the wrist, mitigating the cause of ulnar nerve entrapment.
