Fibrous muscular contractures: treatment with a new direct contact microwave applicator operating at 915 MHz.

A patient having bilateral contractures of the rectus femoris and brachial biceps muscles due to pentazocine injection was treated with a regime of heat and stretch. Heat was provided by a new air cooled direct contact applicator operating at 915 MHz. Stretch was applied by adding weights to a cable which was attached to the arm or leg to be stretched. While the left and right elbows which were limited by the contracted biceps were not stretched sufficiently to achieve a normal range of motion, the rectus femoris muscle on both sides did achieve a normal range of motion.
