Forward Head Posture Fix
6.2.1 The neck is extended and rotated as far as possible in the opposite direction to the operator. If still present, the platysma is now completely resected, leaving the superficial cervical fascia in place. On the surface of the sternocleidomastoid muscle, under the superficial cervical fascia, three structures can clearly be seen which cross the muscle (1) the 5 sternocleidomastoid muscle Fig. 6.3 Sternocleidomastoid muscle Fig. 6.3 Sternocleidomastoid muscle scm sternocleidomastoid muscle c clavicle 1 clavicular head of sternocleidomastoid muscle 2 sternal head of sternocleidomastoid muscle The accessory nerve originates in the cranium from the union of the vagal accessory nerve (parasympathetic fibers visceral effector) and spinal accessory nerve (somatic motor) it exits from the posterior foramen lacerum and divides once again - the vagal portion (internal or medial branch) joins the vagus nerve and participates in innervating the larynx.

About 5-10 of tumors grow directly into surrounding tissues, increasing both morbidity and mortality. Microscopic or gross tumor invasion, which can occur with both PTC and FTC 19 , may involve neck muscles, blood vessels, recurrent laryngeal nerves, larynx, pharynx, and esophagus, or tumor can extend into the spinal cord and brachial plexus. The symptoms are usually hoarseness, cough, dysphagia, hemoptysis, and airway insufficiency or neurological dysfunction. Extrathyroidal tumor extension usually leads to lymph node and distant metastasis 67 . The tumor was locally invasive in 115 of our patients (8 of those with papillary and 12 of those with follicular carcinoma) 10-year recurrence rates were 1.5 times and cancer-specific death rates were five times those of patients without local tumor invasion, and nearly all with tumor invasion died within the first decade 19 .
Surgery As they are very vascular, pre-op embolisation of large tumours is carried out and several units of blood should be crossmatched. Surgical excision of the tumour an incision is made along the anterior border of sternocleidomastoid and the carotid artery bifurcation exposed. The external carotid artery is often clamped or isolated by placement of a shunt from the common carotid into the internal carotid artery to reduce the blood flow to the tumour. Transcranial Doppler can be used to monitor distal flow. If the tumour is significantly adherent or invading an artery wall, it may be necessary to excise an arterial segment replacing it with a length of saphenous vein. Craniofacial surgeons are involved if the tumour extends high into the neck.
Anaesthesia Local anaesthesia has the advantage of allowing direct evaluation of the patient's neurological status without sophisticated monitoring. This enables the surgeon to operate on the majority of patients without the need for a shunt. General anaesthesia has the advantage of improved airway control and patient comfort during prolonged operations. However, it does require the use of shunts, and selective shunting requires the use of EEG, stump pressures, transcranial Doppler and or some other form of cerebral monitoring. Incision An incision should be made along the anterior border of the sternocleidomastoid muscle. An oblique incision is usually made in the skinfold over the carotid bifurcation.
The gland, and any substernal component. The lateral neck is palpated to evaluate for any clinically obvious lymph nodes. We prefer to do this from behind the patient so as to feel beneath the sternocleidomastoid muscle and to be able to compare both sides of the neck simultaneously. The vocal cords are then evaluated either by indirect laryngoscopy or directly by using the flexible laryngoscope. The vocal cords may have either diminished mobility or complete paralysis from compression of the RLN (less common) or direct invasion of the nerve. Even if the patient has no hoarseness, it is imperative that the cords are visualized as slow compression of the RLN may have allowed the contralateral cord to compensate for the paretic cord. Finally, a rough estimate of the patient's calcium level is obtained by performing Chvostek's test by tapping in the pretragal area a positive test is an involuntary twitch of the lips. Up to 10 of patients who are normocalcemic will have a positive...
Depending upon how massive the enlargement is, various techniques may need to be employed to obtain access and deliver the gland. The patient must be placed in as much cervical extension as is safe to passively pull the thyroid out of the chest and into the neck as far as possible. The skin incision is generally larger, and extends at least from the medial aspects of the sternocleidomastoid muscle on each side of the neck. The subplatysmal flaps are sometimes raised to the level of the hyoid bone. Removing the strap muscles can be difficult as they are stretched, thin, and overlie engorged veins. Careful dissection is a must to prevent bleeding. If the superior aspect of the gland is enlarged, then the strap muscles are separated as superiorly as possible (they are innervated via the ansa hypoglossi which enters inferiorly). The superior laryngeal nerve is at great risk in massively
The spinal part of the GSE accessory nerve originates from a cell column located in the anterior horn of the first five or six cervical segments in the lateral position. The radicular fibers originating from these cells curve posterolaterally and emerge from the lateral side of the cervical cord between the dorsal and ventral roots of the spinal nerves. They innervate the sternocleidomastoid muscle of the same side and the upper portions of the trapezius.

It is attached to the anterior margin of the manubrium, the clavicle and the mandible. C
An incision is made in a skin crease about 2 cm cephalad to the clavicles. Once a surgeon gains more experience with this procedure, the transverse incision decreases in length from about 8 cm to about 4-5 cm. This generally results in an imperceptible scar, and negates the benefits of endoscopic assisted thyroidectomy, a much more complex and lengthy procedure. Superior and inferior flaps are raised in a subplatysmal plane. These really only need to be done in between the sternocleidomastoid muscles as more lateral dissection does not improve visualization. This is the basis for reducing the size of the incision to 4 cm in primary cases.

The initial priority is to assess the child's visual development and to treat any co-existant strabismus, ametropia and amblyopia. When severe unilateral ptosis covers the visual axis there is a risk of occlusion amblyopia and ptosis repair is required urgently. Similarly, bilateral ptosis with a marked chin-up head posture may require early intervention. If visual development is normal then most surgeons would delay surgery to about 4 years of age when more accurate pre-operative measurements are possible, and yet is prior to school age. The choice between levator resection and brow suspension depends on the levator function.
E If this is a cyst, a lump is present just deep to sternocleidomastoid at the junction of its upper and lower On palpation the swelling is usually ovoid, smooth and firm or may be relatively soft in early stages, fluctuant and may transilluminate. 2 are bilateral. The external opening of a branchial sinus or fistula is at the junction of the middle and lower 13 of the anterior edge of sternocleidomastoid.

It is bounded superiorly by the apex formed by the convergence of the trapezius and sternocleidomastoid muscles, inferiorly by the clavicle, anteriorly by the posterior margin of the sternocleidomastoid muscle, and posteriorly by the anterior margin of the trapezius.
The main muscle of inspiration is the diaphragm. Contraction and downward motion of the diaphragm causes a negative pressure in the chest, which draws in air. Other than the diaphragm, there are accessory muscles of inspiration (pectoralis major and minor, ser-ratus anterior, sternocleidomastoid, scalene muscles, levatores costarum, serratus posterior superior). They may be vital to survival in certain chronic pulmonary diseases.
There is much debate about the need for neck dissections in well-differentiated thyroid cancer. Some retrospective reviews have reported that lymph node metastases do not impact on the overall survival of this disease (with one older report showing an improvement in survival in patients with lymph node metastases, though this was not controlled for patient age). Other prospective reports have shown a slight survival benefit in bilateral neck dissections for papillary cancer. Common practice lies somewhere in between these extremes. The days of the lumpectomy are fading away, being replaced by the functional neck dissection for any patient with a node-positive neck. The functional neck dissection usually includes all of the node-bearing tissue in the anterior neck except for the submandibular triangle (level I). Most important to dissect is level VI, or that area between the omohyoid muscles, inferior to the thyroid cartilage, and superior to the thoracic inlet. All major neurovascular...
Empathy, or the ability to feel the feelings of others, also relies on the mirror neuron system and predictions 63 . When we observe the nonverbal behaviors associated with human emotion, such as a person's facial expression, posture, or head position, mirror neurons in one's own brain become active, in the same way they would if we were performing those same nonverbal emotional behaviors. We know what they feel, because our brain predicts that they feel the way we would feel if we were moving our face and body in the same way. We essentially read the minds of others by predicting that others are like ourselves 59 .
When cervical lymph node metastases are found, modified neck dissection sparing the sternocleidomastoid muscle is usually advised 114 . This should not be done prophylactically when lymph node metastases are not present. Patients with cervical lymph nodes metastases, those with primary tumor invading beyond the thyroid capsule, and women older than 60 years appear to benefit most from modified radical neck dissection 115 . Lymph node surgery is discussed in detail in Chapter 13 by Mr John Watkinson.
Beneath the tectum is the tegmentum, which includes some structures involved in movement. Red nucleus activity is high during twisting movements, especially of the hands and fingers. The substantia nigra smooths out movements and is influential in maintaining good posture. The characteristic limb trembling and posture difficulties of Parkinson's disease are attributable to neuronal damage in the substantia nigra.
Palpation is best performed by standing behind the patient. The patient should lower the chin slightly as this will aid relaxation of the neck muscles. Both hands, each with its thumb in the nape of the neck, should be used simultaneously to palpate the gland. The patient can be asked to repeat the swallowing exercise at intervals as described above. However, for the patient's comfort it may be necessary to give the patient a drink of water to make swallowing easier.
The group can engage in a discussion of how being an effective provider of support means being aware of the needs of the individual and being able to match the needs with the appropriate type or provider of support. If one cannot provide what is needed, referring the person to another resource can be a form of support. A second exercise provided members with the opportunity to provide emotional support by role playing how to be an effective (active) listener. The facilitator can list on the board active listening behaviors. These include body posture oriented toward speaker, eye contact with speaker, and acknowledging the speaker's comments. The active listener acknowledges that he or she understands what is being said by restating essential points and confirms that the person is finished talking by asking if he or she has more to say. Members can practice active listening in a supportive relationship through role play. Two group members can practice speaking and active listening in...
Mote displacement of the thorax, thus allowing the setting in motion of general movements. Between 14 and 16 weeks, the dependence of general movements on startles decreases, but is still significant. Around 14 weeks, pelvic and shoulder joints acquire independence of movement from trunk muscles, trunk and neck muscles are no longer closely tied, and the skeleton, so far only cartilaginous, begins to harden and solidify 20 . The limbs are, however, still too weak and short to upturn independently the greatly increased fetal body. Although startles progressively lose their power to cause a pronounced lift of the fetal body, dependence on this propulsive mode is still significant. By 17 weeks, the fetal body has acquired sufficient strength, behavioral independence and adequate proportions to perform general movements autonomously. Dependence on startles becomes absent by 20 weeks. By then, startles no longer act as propulsors, but, as in the neonate, merely cause a pronounced extension...
If the therapist wants to facilitate rolling from the supine into the prone position, the first part of the activity is a concentric action of the flexor chain (trunk flexors, neck flexors and hip flexors) (see O Fig. 11.2 a, b). When the patient rolls from the mid-position (see O Fig. 11.3 b) into the prone position, we see an eccentric activity of the extensor chain (trunk extensors, neck extensors and hip extensors). To facilitate this eccentric activity we should move our hands to the ischial tuberosity and posterior on the top of the shoulder to resist the extensor chain. We ask the patient to let us push him forward, but slowly.
Second, Argyle e.g. 1987) has published a myriad of studies on nonverbal behaviour, including such important areas as postural moulding and eye-gaze in the regulation of social encounters. He suggests that postural moulding (i.e. the copying of body posture) often indicated that the dyad concerned were getting on well with each other, while eye-gaze (and the breaking of eye contact) was important in synchronizing conversations, signalling to the other when you wished him or her to take over, for example. 4 Describe the actions of the participants, including both verbal and nonverbal behaviours (where this is possible). Some coding may be needed for some of the variables (e.g. body posture), to aid recording. The sequence of actions over time is likely to be important, and needs to be carefully noted. The presence of the observer seemed to have had no effect on the behaviour of the participants, and the observation felt ethically comfortable, as it was watching people in their everyday...
Cerebral palsy is the end result of damage to the developing brain, resulting in problems with movement, tone and posture. Despite public misconception, intellect is often not affected. The major cause in premature infants is PVH and PVL. As noted below these complications can also affect sight and hearing. In most cases the newborn will leave the nursery with no apparent movement disorder. As the child becomes older and the nervous system matures, changes in tone become obvious. A picture of hemiplegia, diplegia or quadriplegia can be apparent, often with reduced truncal tone (causing problems with sitting) and dystonic movements. Early developmental physiotherapy is vital to encourage good posture to enable the child at risk to progress through each stage of normal development. The use of folded sheets as boundaries (similar to a nest), side lying to bring the newborn's hands together in the midline near the face are measures that should be routine in any nursery. In the clinic...
There is severe ptosis with poor levator function and a non-progressive external ophthalmoplegia where typically the extraocular movements are severely restricted and the eyes deviated downwards. On attempted upgaze the eyes converge.These features result in a marked chin-up compensatory head posture.
