Strain-counterstrain

Last updated: December 18, 2024

Summary

Strain-counterstrain (or simply counterstrain) is a passive functional (indirect) technique developed by Dr. L. H. Jones in 1955. It was originally developed after he observed relief of pain from what he would later term “tender points,” and improvement of function after a patient assumed a pain-free position. Tender points are small, edematous, hypersensitive areas of tenderness located in the myofascial tissue that are elicited upon palpation. They are typically located near muscular attachments to the bone, overlying tendons, and in the belly of major muscles. There are more than 200 identified tender points typically correlating to specific positioning of the body with some exceptions called maverick points. However, the mainstay of the strain-counterstrain system is placing a particular joint or region of the body in the most comfortable and least painful position; this typically correlates to anatomically shortening the muscle between two attachments.

Overview

Tender points (Jones points)

Small, hypersensitive areas located in tendons, ligaments, or muscles that typically do not radiate pain when pressed
Caused by dysfunctional neuromuscular reflexes
Associated with somatic dysfunction
- Anterior tender points: typically related to flexion dysfunctions
- Posterior tender points: typically related to extension dysfunctions
- Lateral tender points: typically have more of a side bending and rotational component
Treated with counterstrain

Tenderpoints do not radiate pain when pressed.

Technique

Description
- Counterstrain is a passive, indirect technique.
- Developed by Dr. L. H. Jones in 1955.
Goal: alleviate the pain (by at least 70%) by placing the patient in a position of ease
Indications: presence of a tender point
Contraindications
- Absolute: trauma, severe illness, severe spondylosis
- Relative: non-cooperative patient, connective tissue disease, pain while performing technique, acute injuries in the treatment area (e.g., infections, burns)

Procedure

Identify the tender point
- Apply a few ounces of pressure when palpating.
- Try to use the same amount of pressure when assessing the tender points.

Establish a tenderness scale: e.g., a 1–10 tenderness scale

Place the patient in a position of ease
- Continuously monitor the tender point using a light touch
- Reapply firm pressure to achieve at least a 70% reduction in tenderness

While the patient is relaxed, maintain the therapeutic position for 90 seconds and monitor for release

Slowly return the patient to a neutral position

Reassess for tenderness
- No more than 30% tenderness should remain.
- Monitor for post-treatment emotional reactions.

The most painful tender point should always be treated first.

AC1 (maverick point)	High on the posterior edge of the ramus of the mandible between the earlobe and the angle of the mandible (near the transverse process of C1)	Rectus capitis anterior muscle	Position: supine Marked rotation away from the tender point
AC2	Anterolateral tip of the anterior tubercle of transverse process Lateral muscle mass at the corresponding level	Rectus capitis muscles (anterior and lateralis)	Position: supine Flexion Sidebend and rotate away from the tender point.
AC3		Longus capitis muscle
AC4		Longus capitis muscle

Most anterior cervical points are treated with flexion, sidebending away, and rotating away from the tenderpoint (F SARA).

Maverick points are tender points that do not follow the general rules of counterstrain and do not resolve when the muscle is shortened (e.g., AC7, PC3 midline cervical tender points).
