Trigger Point Locations - Rhomboid

You can find your own trigger points by using your thumb or finger to press on the spots shown in the picture. They are not difficult to find. Or you can ask a friend or family member to help you. Press firmly in a step-by-step manner until you find the exact spot that is tender. That is the trigger point.

By pressing firmly on the trigger point, and holding that pressure for several seconds, you will discover the pain lessens dramatically. In fact there are devices that can help you do this. We recommend a device called a "TheraCane" that can be purchased at many stores such as Sammons Preston Medical Equipment that has a mail order catalogue that can be contacted at 1 800 323-5547. The TheraCane is their item # 5244. The TheraCane can use be purchased at many local pharmacies.

Unfortunately this technique, known as acupressure, or shiatsu, provides only temporary relief. Some physicians inject drugs like Novocaine into trigger points, but these offer only temporary relief as well, and can cause scar tissue in the muscle.

Isometric Contraction Testing - Rhomboid

A painful muscle will become more painful if it is forcefully contracted (flexed). Use this picture to test this for yourself with the assistance of a friend or family member.

Follow these Directions
Sit in an armless chair with the painful side forearm against the small of your back, palm out, while your assistant places on one hand on your painful-side shoulder and the other hand along your spine. Attempt to squeeze your shoulder blades together, while your assistant prevents you from doing so.
