International Institute for Corrective Muscle Therapy, Inc.Crossfiber Corrective Muscle Therapy


International Institute has been at the forefront of Crossfiber Corrective Muscle Therapy℠ for over 30 years. 

In 1946 Thérèse C. Pfrimmer became a forerunner in creating a whole new field of muscle therapy, one which focused on the correction of serious muscular conditions as well as everyday aches and pains. The key to her discovery was “Crossfiber”—working in short strokes across the muscle fibers, unearthing the causes of muscle distress hidden between the fibers.

Since then Crossfiber Corrective Muscle Therapy℠ has changed the field of healthcare substantially. It is our mission to facilitate an even greater understanding and awareness of how medical doctors, physical therapists and chiropractors could utilize this tool more fully in meeting the needs of their patients.

Our program is the result of 30 years of clinical experience in bringing together the most relevant factors to create a complete mastery of soft-tissue correction. International Institute offers training programs to complement each level of health care provider.

We invite the public not only to familiarize themselves with the value of Crossfiber through our website but also to direct the attention of their health care provider to this indispensable means of helping them.
