Study Summary

Penetration force and drag force of 3 market leading monopolar EMG needles

50% less peak force during insertion


Ambu's monopolar needle requires about half the peak force during penetration. Ambu's needle has a back bevel cut design making it sharper. Previous studies have shown that patients prefer sharper needles.1

50% less drag force after insertion


The Ambu Monopolar Needle exposes patients to half the drag force of the market leading needle. Drag - or friction force - is extremely significant in EMG studies when the needle will be re-positioned and potentially used in multiple locations.

What our customers say

“I’ve had access to many different needles throughout my career. The Ambu monopolar needles give a great signal and ensure the best patient tolerance out of any that I’ve used.”

Dr. John A. Roffers – Glendale, WI

“I especially love the Ambu monopolar needles. There is markedly less resistance with needle insertion and advancement in the muscle compared to the needle I have been using forever."

Dr. P. Andrew Nelson - Medical College of Wisconsin
