While using no pressure to position action in opening the mouth, when the hyoid is stabilized by the finger for treatment, the index finger of the practitioner's the infrahyoid, an action which would be counteracted by muscles attaching to the maxillae and the zygomatic bones. The complex of stabilization and counterpressures can, they suggest, 'interfere with the function of the craniosacral sys tem and contribute to temporomandibular dysfunction'. Trigger points in the posterior belly of digastriC can refer pain to the upper part of the sternocleidomastoid muscle as well as neck and head pain while triggers in the anterior belly refer to the lower incisors. If a trigger in digastric is referring into the lower incisors then a rapid tensing of the anterior neck muscles by the patient ('pull the corners of your mouth down vigorously') will activate the trigger and reproduce the pain. The digastric trigger point target zone includes the area of the stylohyoid muscle, whose pain pat tern is not yet clearly established but is presumed to be sim ilar (Simons et aI 1999). The posterior attachment of digastriC as well as the stylo hyoid has been previously discussed together with the mastoid and styloid processes (pp. 369-371). The intraoral

Far more likely to produce damage, however, are the influences of the dan gerous potentials of the powerful forces acting upon the supple skull during the birth process. Among the factors that can produce cranial damage dur ing birth are (Biedermann 2001, 2005): • too rapid a transit through the birth canal that precludes the opportunities for 'normal' molding to occur • too ex tended a period in the birth canal with excessive compression forces operating on the delicate mem branes, sometimes for many hours (Byrne et al 1993, Magoun 1976)

As Milne (1995) explains: A newborn baby has no sutural interlocking or interdigita tion between adjacent cranial bones. The bony plates of the cranial vault arefree to float like icebergs in an elastic sea of membranous dura. The mechanism of thefontanelles, pliant cartilage, tender membrane, open sutures, cerebrospinalfluid and falx and tentorium has evolved so that what is, evolu tionarily, a huge head can pass through a small birth canal intact.

Reprod uced Under normal conditions any minor distortions imposed w ith perm ission from Carrero (2003). during birth will resolve as a result of the influences of the reciprocal tension membranes within a matter of days, greatly assisted by the forces involved in suckling and crying (Frymann 1966). In many instances, however, such a recov ery is not achieved due to the degree of distortion created with - sometimes disastrous - consequences in health terms (Arbuckle 1948, Frymann 1976) . Dis tortions and deformities are often easily noted and may be the reason the parent(s) seeks assistance. Behavioral problems such as incessant crying, feeding difficulties, 'head banging' or frank illness might cause parents to attempt to find appropriate professional help. Clearly, if the healthcare provider consulted is ignorant of the influence of cranial function on health, whatever is offered will be less than sat isfac tory. After birth the pliability of the infant cranium continues to allow damage to occur more easily than once ossification has taken place. Falls and blows are obvious pOSSibilities, and indeed probabilities during the early years of life. If severe enough these may produce problems similar to those that can occur during childbirth. Biedermann (2001 ) describes what he terms 'KlSS' children in whom the main clinical feature is torticollis, often com bined w ith an asymmetrical cranium, postural asymmetry and a range of dysfunctional symptoms. KISS is an acronym for kinematic imbalances due to suboccipital strain. Biedermann notes: '[KlSS imbalances] can be regarded as one of the main reasons for asymmetry in posture and con sequently asymmetry of the osseous structures of the cra nium and the spine.'

It is easy to see how, as a result of the availability of all Liebenson's insightful sta tements lead us to question these data, 'information overload' might occur, with no clear how it may be possible to find a way through the maze of indication of where to begin therapeutic intervention. informa tion and to identify and extract the key elements Liebenson (1996) states the clinical conundrum as follows: in each particular case.

In summary form, these seven joints are (more detailed discussion follows): • glenohumeral (scapulohumeral) joint is a true joint in tha t it has two bones directly articulating (the head of the humerus with the glenoid fossa), is lined with hyaline cartilage, has a j oint capsule and is filled with synOVial fluid. The humeral head may glide up or down the fossa, anteriorly, posteriorly and with inversion or eversion • suprahumeral (subdeltoid) joint is a false joint in tha t it does not have a direct apposition of two bones nor does it have an articulating surface; instead it is comprised of a bone (humeral head) moving in respect to ano ther bone (acromioclavicular joint) and the overhanging cora coacromial ligament

If so, it indicates intraarticular dysfunction. 3. Is active movement (controlled by the patient) restricted or does it produce pain in one direction of movement, while passive movement (controlled by the practitioner) in precisely the opposite direction also produce pain (and/ or is restricted)? If so, the contractile tissues of the area (muscle, ligament, etc.) are implicated. This can be confirmed by resisted tests. 4. Do active movement and passive movement in the same direction produce pain (and /or restriction)? If so, joint dysfunction is probable. This can be confirmed by use of traction, compression and gliding of the joint. Resisted tests are used to assess both strength and painful responses to muscle contraction, either from the muscle or its tendinous attachment. These tests involve producing a maximal contraction of the suspected muscle while the jOint is kept immobile somewhere near the middle of range posi tion. No joint motion should be allowed to occur during such an assessment. Resisted tests may usefully be performed after test 3 (above) to confirm a soft tissue dysfunction ra ther than a joint involvement. Kaltenborn suggests that before per forming the resisted test, it is wise to perform the compres sion test (2 above) to clear any suspicion of jOint involvement. These thoughts should also be kept in mind when the Spencer sequence, described in Box 13.6, is ca rried out.

This additional elongation may make the taut fibers more palpable and precise compression possible; however, it may also stretch ta u t · fibers so much that they are difficult to palpate or it may aggravate trigger points due to the tension increased by the stretch.

The thumb is then returned to the middle of the muscle belly and used again (or the opposite thumb can be used) to glide medially toward C7 or Tl . These alternating gliding techniques are repeated to spread the sarcomeres and ta ut bands from the muscle's center toward its attachment sites (see p. 277). A double thumb glide applied by spreading the fibers from the center simultaneously toward the two ends will traction the shortened central sarcomeres and may produce a pro found release (see Fig. 9.6). Full-length glides may reveal remaining thickness within the tissue, which needs to be readdressed with compression or other techniques. Myofascial release may also be used to soften and elongate the upper fibers. Central trigger points in these upper fibers refer strongly into the cranium and particularly into the eye. Attachment trigger points and tenderness may be associated with ten sion from central trigger points and may not respond well until central trigger points have been abolished. f NMT FOR MIDDLE TRAPEZIUS Figure 1 3.23 The m iddle tra pezius fibers may be l i fted a way from u nderlying tissue, ro lled between the thumb and fingers or This portion of the trapezius may be outlined b y drawing compressed to rel ease trigger poi nts.

While seated cephalad to the patient's shoulder, the prac titioner grasps the middle fibers of the trapezius with both , hands (Fig. 13.23) . Compression may then be applied to the mid-belly region of the upper half of middle trapezius, where its central trigger points are usually found. These tis sues may also be manipulated by rolling them between the fingers and thumb. The lower fibers of the middle trapezius normally lie flat to the torso and are not easily lifted by the fingers. Those fibers are addressed with gliding strokes after the lower trapezius has been treated.
