of the pectoralis major muscle. Avoid the breast tissue when working on a woman.
Connective Tissue Therapy
Perform the fanning stroke on the upper portion of the chest. Begin with the sides of the thumbs touching each other. The tips of the fingers of both hands may be used as an alternative to the thumbs. Slowly spread them apart, stretching the tissues. Keep the strokes small, spreading the thumbs or fingers 2 or 3 inches apart with each stroke.
Start at the midline of the chest over the sternum, just above the level of the breasts. The fanning strokes move upward toward the clavicles. Repeat the stroke a number of times, covering the entire upper segment of the chest. The intention is to free the fascia of the upper thorax, creating a sense of lift in the chest.
SESSION IMPRESSION
THE CHEST
he client is a 10-year-old boy named Joey, who has asthma. He has been picked on in school because of
T
his small stature, and because he cannot participate fully
in sports activities. His mother wants him to receive inte-
grated deep tissue therapy to help alleviate the condition
and possibly boost his self-esteem.
is severely constricted. There are noticeable hollow areas
under the clavicles and along the borders of the anterior
deltoids, indicating that the pectoralis minor muscles are
extremely contracted. The central sternal region of the
chest is lifted, but in a strained manner. This position of
the chest may also partly be a consequence of struggling
to breathe during asthma attacks.
The focus of the session was to relieve tension in the chest and ease restrictions in the breathing muscles. Because Joey was a minor, his mother sat in on the ses­sion. Based on observation and the information gathered about his asthmatic condition, the areas chosen to focus on included the pectoralis major and minor, subclavius, scalenes, intercostals, and diaphragm. A connective tissue approach to these muscles was mandated because of the child’s sensitivity to touch in the chest area.
Joey responded well to the front to back polarity contact on his sternum and upper back. He visibly relaxed, and his breath deepened. Swedish massage strokes were used to warm up the muscles thoroughly before the deep tissue/ connective tissue strokes were applied. The integrated deep tissue protocol was followed, but with full attention given to sensing a melting of the tissues before applying any further pressure or moving through the muscle fibers.
Deep Tissue/Neuromuscular Therapy
SEQUENCE
1. Pectoralis major (attachments and belly)
2. Subclavius
3. Intercostal muscles (from supine and side position)
4. Diaphragm
5. Back muscles (serratus posterior superior and inferior)
It is likely that the chest muscles will be re­stricted in many areas, because the breathing
mechanism is compromised in the majority of the adult population as a result of stress and the lack of encouragement of full expression of feeling and sensa­tion. The reductions of trigger points not only assist in opening up the breathing but also are instrumental in rebalancing the shoulder girdle and freeing the ribs.
The chest muscles were addressed in layers, from superficial to deep. Many trigger points were encountered in the intercostal muscles. As a trigger point was pressed, Joey was encouraged to breathe deeply and imagine the point melting. He en­joyed participating in the process and felt a sense of accomplishment when the uncomfortable feelings generated by the trigger points dissolved. The diaphragm was contacted and massaged very carefully.
The session was concluded with long, Swedish strokes along the erector spinae and with fingertip raking into the intercostal spaces between the ribs in the back to balance the work performed on the front of the chest cavity. After the session, Joey’s mood was much lighter. He was thrilled to be able to take fuller breaths without struggling, and he commented to his mother how much broader his chest and shoulders felt. He was extremely proud of himself. Joey was shown the door frame stretches for the chest muscles, and it was suggested that he practice them every day to maintain the newfound length in his pectoralis major and minor muscles.
Topics for Discussion
1.
Give at least three reasons for beginning a series of deep
tissue sessions with chest work.
2. Describe several possible manifestations of chest con-
striction along with the muscles involved.
3. What precautions should be taken when performing
deep tissue therapy on the diaphragm muscle?
4.
How might restricted breathing patterns be revealed
by observing a client’s thorax?
5.
Where are the most likely areas for trigger points to
form in the thoracic region, and why?

Pectoralis Major (Attachments and Belly)
Origin:
Clavicular—medial half of the clavicle. Sternal—sternum to the seventh rib, cartilages of upper
six ribs.
Insertion: Lateral lip of the bicipital groove of the humerus. Action: Adduction of shoulder. Medial rotation of shoulder.
Clavicular—shoulder flexion, medial rotation of shoul-
der, horizontal adduction of humerus.
Sternal—adduction of humerus diagonally downward,
anterior shoulder stabilizer.
Pectoralis Major (Origin)
Strokes
r Elongation stroke on the sternum, just lateral to the mid-
line, from the xiphoid process to the manubrium, using the fingers or the thumb (Fig. 6-8).
r Elongation stroke along the inferior border of the medial
half of the clavicle, using the fingers or the thumb. Move medial to lateral. Feel for small knots and stringy fibers. If they are tender or refer pain, work on them with cross-fiber strokes and direct compression.
FIGURE 6-9 Contacting the attachment of the pectoralis major on
the lateral lip of the bicipital groove of the humerus.
Insertion of the pectoralis major. Perform the side-to-side
r
stroke and static compression with the fingers on the lateral lip of the bicipital groove of the humerus (Fig. 6-9). To locate it, take the client’s arm to an abducted position. Slide your fingers along the border of the pectoralis major and the anterior deltoid to reach the point of attachment on the humerus. It is superior to the deltoid tuberosity on the lateral lip of the bicipital groove. Check for trigger points. If any are found, pause there for several seconds while checking with the client about the level of pain reduction.

clavicular attachments of the pectoralis major.
Pectoralis Major (Belly)
The pectoralis major muscle has three major segments. They are named after their sites of
origin: clavicular, sternal, and costal. Trigger points in the upper or clavicular portion may be found along the lateral border, underneath the edge of the anterior deltoid muscle. They refer pain throughout the anterior deltoid and into the area of the pectoralis major near the trigger point.
Trigger points in the sternal section tend to accumu­late in the medial and lateral portions between ribs 3, 4, and 5, near the insertion points of pectoralis minor. Check along the inferior border of the costal section of the muscle for trigger points. The pain pattern is into the front of the chest and down the arm.
Trigger points in the lower section of the muscle tend to form along the lateral border. They refer pain into the breast and nipple.
Heavy lifting, prolonged holding of the arms in an abducted position, and postural changes related to emotional stress may all contribute to the formation of trigger points in this muscle.
Strokes
r The client’s arm is still in the abducted position. Using
your knuckles, perform the elongation stroke from the sternum to the insertion on the humerus in several strips (Fig. 6-10). Begin the first strip just inferior to the clavicle. Begin the last strip across the muscle at the xiphoid process.
r With a female client, the knuckle stroke should only be
done on the upper chest, superior to the breast tissue. At the level of the breast, stroke outward, using the fingers or thumb, from the sternum to the medial border of the breast.
Subclavius (Fig. 6-11)
Origin: Upper border of the first rib. Insertion: Groove on the inferior surface of the clavicle. Action: Depresses and moves the clavicle forward. Stabi-
lizes the clavicle during shoulder movements.
A commonly occurring trigger point is found on the medial side of the subclavius, near the
manubrium. Its referral zone is along the in­ferior border of the clavicle and down the arm into the thumb side of the hand.
Strokes
r
Stand at the side of the table, and face the inferior border of the client’s clavicle. The client’s arm is flexed at 90°. Hold it slightly inferior to the elbow. Drawing the clavicle slightly away from the chest wall for easier access to the subclavius muscle, traction the arm toward the ceiling.
r
Using the pads of the index and middle fingers or the pad of the thumb, stroke under the inferior border of the clavicle from the medial to the lateral end.
Chapter 6 The Fundamentals—Breath and Support 87
FIGURE 6-11 Accessing the subclavius.
Intercostal Muscles
Origin:
External—from the lower border of each of the upper
11 ribs.
Internal—from the cartilages to the angles of the upper
11 ribs.
Insertion:
External—superior border of the rib below the origin. Internal—superior border of the rib below the origin.
Action:
External—elevation of ribs during inspiration. Internal—depression of ribs during exhalation.
Intercostals (Supine Position)
DAR
FIGURE 6-10 Elongation stroke on the clavicular, sternal, and
costal sections of the pectoralis major.
Trigger points are likely to be found in concen­tration along the borders of the ribs where the
intercostal muscles attach. Contracted muscles related to inhibited breathing are the probable cause of their formation.
Strokes
r Begin at the base of the rib cage, in the rib space between
the 10th and 9th ribs. Place your fingers between the two ribs. Allow the fingers to sink into the tissues until resistance is met (Fig. 6-12).
r Perform a short, side-to-side stroke, feeling for deviations
in the tissues (i.e., stringy fibers, tiny knots). Hold with static compression on tender points until pain diminishes. The thumbs may be used instead of the fingers if more pressure is required.
r
Continue with this procedure, working between each pair of ribs, to the clavicle. Be thorough.

shoulder. Hold the extended arm, and slowly increase the stretch while your fist is placed against the client’s scapula to prevent the client from rolling backward too far (Fig. 6-17). This position stretches the pectoralis major muscle.
ACCESSORY WORK
1. Perform an elongation stroke on the erector spinae and paraspinal muscles. Using the forearm, begin the stroke between the scapula and spinous processes on one side of the back. The forearm is parallel to the spine until you clear the inferior angle of the scapula. Then, it is rotated perpendicular to the spine to make contact with a broader section of the back. Continue the stroke to the iliac crest of the pelvis (Fig. 6-18). Repeat on the other side of the back. Press points along the inferior border of the 12th rib, which is near the attachment of the diaphragm muscle (Fig. 6-19). Both sides may be palpated simultaneously. Begin with the thumbs on either side of T12, and move

2. Concentrate on diaphragm reflex points on the foot (Fig. 6-20). Press points along the diaphragm line on the plantar surface of the foot, moving medial to lateral. The line is located slightly inferior to the metatarsal bones, and it runs all the way across the surface of the foot. It is easy to distinguish, because the color of the skin is darker above the diaphragm line and lighter below it.
CLOSING

The Back and Spine

◗ GENERAL CONCEPTS
The spine acts as the primary support structure for the entire body. Functional alignment of the spine is essential so that it can carry the three major weights that are connected to it (the head, rib cage, and pelvis) without adding unnecessary stress in the muscles of the trunk. A poised, balanced spine results in the effortless elongation of the trunk that is associated with healthy posture. The muscles attached to the spine must be free of restrictions so they can achieve the equalization of forces along the spinal column that allows a balanced relationship between its components. This is the next goal in the integrated deep tissue series.
The spine is constructed so that many muscles and ligaments attach to it in a lattice-like pattern, allowing a great deal of mobility and flexibility along with stability. The spinal column is capable of forward and side flexion, extension, and rotation.
◗ MUSCULOSKELETAL ANATOMY
AND FUNCTION
Spinal Column
The spinal column consists of 33 bones: 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, and at birth, 5 modified sacral vertebrae and 4 small vertebral remnants forming the coccyx. The bones of both the sacrum and the coccyx fuse later in life, leaving 24 functional vertebrae in the adult. Twenty-three intervertebral discs are sandwiched between the vertebral bones (Essential Anatomy Box 6-3 and Fig. 6-21).
All vertebrae except C1 are composed of two parts: a rounded body on the anterior side, and a posterior segment, called the vertebral arch. The vertebral arch is a complex
structure with several landmarks. The spinous and transverse processes are on the vertebral arch; these provide attachment sites for many muscles and ligaments. The opening between the vertebral body and arch is called the vertebral foramen. Lined up within the spinal column, the foramen form a tun­nel, called the vertebral canal, within which the spinal cord is located. See Figure 6-21A for an illustration of a vertebra.
Stacked vertebrae also create bilateral holes on the hori­zontal plane. These are called the intervertebral foramina, and they allow the spinal nerves to exit the central nervous system and become part of the peripheral nervous system.
The vertebral bodies are separated by cartilaginous discs. The two components of the disc are a central, compressed fluid core, called the nucleus pulposus, and a tough fibrous covering, called the annulus fibrosus. The discs act as cushions, helping to transfer weight evenly between the vertebrae, and absorbing the shock of the vertical and shearing pressures that occur when we walk, run, bounce, and twist. The discs in the lumbar and cervical segments of the spine are thicker in relation to the height of the vertebrae, allowing greater movement between the individual vertebrae, but the discs in the thoracic segment are smaller, decreasing the amount of possible motion. When adjacent vertebrae are properly aligned, compression on the intervertebral disc is distributed evenly, allowing a smooth downward transfer of weight.
One of the spinal column’s primary functions is to provide an anchor of support and stability for the cranium, thorax, and pelvis. The spinal column has a series of four opposing curves that offset the uneven size and placement of these three weights (Fig. 6-22). The cervical and lumbar curves are concave, while the thoracic and sacral curves are convex. This design creates continuity of weight transfer and shock absorption throughout the spinal column. The vertebral joints where the curves change (C7–T1, T12–L1, and L5–S1) bear the greatest weight load, and must be in best alignment for the spine to be an integrated, stress-free unit.
