Ischemic compression

Ischemic compression is a technique systematized by American physicians Janet Travell and David Simons through their research on muscle pain. Travell is also known as the White House physician who treated President John F. Kennedy’s lower back pain. Together, they mapped painful spots in muscles throughout the body and the areas to which those spots referred pain, publishing their work in two volumes: the upper body volume (1983) and the lower body volume (1992).

The name “ischemic” comes from the physiological response in which blood flow to the area temporarily decreases during pressure, then rushes back when the pressure is released. In fact, after releasing pressure on a spot, you can see the skin turn white and then quickly become red. Simons later recommended using gentler pressure than originally described and waiting for the tissue to release, calling this trigger point pressure release. Today, the technique is widely used by massage therapists, physical therapists, and exercise instructors.

When running your fingers over a muscle, you may feel a band pulled tight like a guitar string. An especially painful spot within this band is called a trigger point. A distinctive feature of trigger points is that pain is not limited to the spot being pressed; it can spread to distant areas. For example, pressing a trigger point in the upper trapezius at the top of the shoulder may cause an ache to spread to the side of the neck and the temple. For more details, see Myofascial trigger point and Taut band.

The premise of this technique is that maintaining steady pressure on a trigger point and waiting allows the tightly contracted area to gradually relax. The explanation is that blood flow, temporarily reduced during pressure, returns after release, making the area feel more comfortable. A reflex response in which the nervous system reduces muscle tension is also thought to occur while steady pressure is maintained.

1. Locating the spot: The practitioner runs their fingertips along the muscle fibers to find a taut band and a painful spot. Pressing it produces a familiar pain that makes you think, “That’s exactly the spot.” 2. Applying pressure slowly: The practitioner slowly presses perpendicular to the muscle with a thumb or fingertip. Pressure is increased only to a level that is painful but tolerable and feels relieving. 3. Waiting: The pressure is maintained for about 30 to 90 seconds. As the pain gradually decreases and the tissue softens, the practitioner follows it a little deeper. 4. Releasing slowly and stretching: The pressure is released slowly, and the session finishes with gentle stretching or movement of the muscle.

When doing this yourself, you can place a massage ball or tennis ball between your back and a wall and lean against it, or lie on the floor and use your body weight to adjust the pressure. This method is particularly convenient for hard-to-reach areas of the back and buttocks.

• People whose neck and shoulders always feel tight, with spots that hurt when pressed (Trapezius pain)
• People who feel heaviness extending to the temples or the back of the head when their shoulders are tight
• People who develop an ache at the side of the lower back or deep in the buttocks after sitting for a long time
• People who have aching along the inner border of the shoulder blade from extensive computer work
• People who have a hard knot remaining in a particular muscle after exercise

• Pressing harder does not necessarily produce a better release. Pressure so strong that you have to force yourself to endure it can make the muscle tense up even more. A suitable level allows you to breathe out comfortably.
• Keep pressure on any one spot to under 1 minute 30 seconds. Pressing the same spot for too long or too many times can cause bruising or increased soreness the next day.
• Some areas should be avoided. Do not press areas where blood vessels and nerves pass, such as the front of the neck, the back of the knee, and the groin; areas where bone can be felt directly beneath the skin; or areas with bruising or inflammation.
• Stop if you feel numbness, tingling, or an electric sensation. Unlike an ache, numbness, tingling, or an electric-shock sensation may be a sign that a nerve is being compressed. Move your hand to a different position.
• You may feel slightly sore the next day. In most cases, this settles within a day or two. For tips on managing it, see Post-massage soreness.

Acupressure often involves rhythmically pressing and releasing acupoints along meridians. Ischemic compression differs in that it focuses on one trigger point within a muscle, maintaining pressure and waiting. Muscle stripping releases a taut band by gliding the hand along it, while dry needling stimulates the same trigger point with a fine needle. For approaches that combine these techniques, see Trigger point therapy and Neuromuscular therapy.
