Upper respiratory tract infections (URI) are typically viral in origin. Decreased host resistance and associated inflammation can lead to secondary bacterial infection. Visceral afferent impulses from the upper respiratory tract facilitate the upper thoracic spinal cord segments, leading to increased sympathetic tone to the structures of the head, neck and lungs. OMM is applied to improve function and motion of these areas. The overall goals are to:
- Improve arterial supply
- Improve venous and lymphatic drainage
- Reduce muscle spasm and improve breathing
- Reduce discomfort
- Balance autonomic reflex disturbances
- Improve immune function
While treating the entire patient Osteopathically, you especially need to focus on improving function and motion in the upper thoracics, upper ribs, cervical region, relevant Chapman’s reflexes and cranial mechanism. Addressing dysfunction at the occipitoatlantal (OA) and atlantoaxial (AA) areas is vital due to their influence on the jugular foramen
Approximately 85% of the venous drainage from the head courses through the internal jugular veins. They pass through the jugular foramen, which is formed at the junction of the occiput and temporal bones along the occipitomastoid suture. The venous drainage through this low pressure system can be impaired by increased tension in the suboccipital region resulting from OA and AA dysfunction.
Important pearl
treating upper thoracic and upper rib dysfunction first will make the cervical spine and cranial mechanism easier to treat
Muscle energy modifications
the HVLA techniques covered today can be easily modified into muscle energy techniques (Chicago-style muscle energy). The setups are somewhat different than the muscle energy techniques already covered for OA and AA and both are clinically effective.
Diagnosis – the occiput is rotated right and sidebent left in relationship to the atlas (posterior occiput on the right). OA RR SL
- Same setup as HVLA.
- After engaging the barrier, instruct the patient to gently turn their head to the right. Maintain contraction for approximately 3 seconds.
- Instruct patient to relax.
- Wait until the muscles completely relax (approximately 2 seconds).
- Re-engage the barrier.
- Repeat above sequence a total of 3-5 times (until no further improvement of motion noted).
- Reassess.
Diagnosis – the atlas is rotated right in relationship to the axis (right posterior atlas). AA RR
- Same setup as HVLA above.
- After engaging the barrier, instruct the patient to gently turn their head to the right. Maintain contraction for approximately 3 seconds.
- Instruct patient to relax.
- Wait until the muscles completely relax (approximately 2 seconds).
- Re-engage the barrier.
- Repeat above sequence a total of 3-5 times (until no further improvement of motion noted).

Anatomic factors that affect breathing
•Upper thoracic vertebrae –Mechanical effects –Sympathetically mediated viscerosomaticreflexes (T1-6) •Ribs •Sternum •OA –parasympatheticallymediated viscerosomaticreflexes •Accessory muscles of respiration •Anterior cervical fascia •Thoracic diaphragm –C3-5 (phrenic nerve) –Upper lumbars(diaphragmatic crus) •T10-12 and the lower ribs –Connection to diaphragm
Dysfunction of the Thoracic Pump
•Over 150 joints are involved in the respiratory mechanism.
- Somatic dysfunctions of the “pump” have direct effects on the viscera
- decreased arterial supply
- decreased venous drainage
- decreased lymphatic drainage
- decreased responsiveness of the respiratory mechanism to body demands (acid/base, oxygen demand, CO2 removal)
Seated vertebral myofascial release
- The child is seated with physician behind them.
- The physician’s thumbs are placed on the transverse processes of the segments to be treated. The physician most often will have each thumb on a different segment. The fingers wrap around the thorax for stabilization.
- This is a direct treatment. Engage the area focusing on the myofascial planes surrounding the vertebrae by working with rotation, sidebendingand flexion/extension. Then begin to work outwardly to engage the surrounding tissues of the diaphragmatic crus,andthe diaphragm. Remember, the focus is within the myofascial structures, not the articular.
Seated upper thoracic and sternal MFR
The upper rib-vertebral-sternal complex is often a hot-bed of somatic dysfunction in people with asthmatic and related disorders.
- Contact the sternum, upper ribs, and upper vertebrae (if possible).
- Directly engage the barrier by moving the ribs, sternum, and vertebrae in whatever way is necessary to bring myofascial release to the entire upper thoracic region.
Seated rib FPR
- Gently grasp both the anterior aspect of the rib, lateral to the costochondral junction, and the posterior aspect over the rib angle, as close to the costotransverse junction as possible.
- Disengage the rib by using a pincer grasp (a gentle anterior-posterior force)
- Once the rib is disengaged gently rock the rib along its long axis until a release is felt.
General Screening Assessment
ribs
Assessment of the ribs should happen in conjunction with the thoracic vertebral evaluation
TART changes over the rib angles
Tenderness
Asymmetry: prominent rib angles
Tissue texture changes
When you find motion restriction/somatic dysfunction of vertebral segments, you should automatically look at the ribs as well.
The ribs attach to the vertebral segments at the same level and above (for example, rib 3 attaches at T2 and T3).
Restricted motion of one will affect the other
ANTERIOR ASSESSMENT

–Biomechanical •Need to make diaphragm more mobile •Need to improve the bellows function of the ribcage •Need to address scalenes/1strib –Respiratory/Circulatory/Lymph •Need better air exchange •Avoid thoracic lymphatic pump technique –Neurological •Viscerosomatics –Metabolic •Breathing is hard work and many with COPD cannot breathe while eating –Behavioral •smoking cessation
Diaphragm
If one thinks of the hemi-diaphragm as an upside-down ladle, then the bowl is the domed portion of the upper diaphragm and the handle is the crus.
Then the ribs outline the rim of the bowl.
The handle is attached to the anterior lumbar vertebrae.
Diaphragm
Principles of MFR
Direct: Identify the restrictive barrier in multiple planes. Engage the tissue in opposition to the pattern of dysfunction. Load a constant force on the area of greatest restriction. Wait for the tissues to unwind or release.
Indirect: Identify the position of free motion in all planes. Place the tissue into the position of ease and maintain this until the tissues release.
MFR for the Diaphragm
- Stand behind seated patient. Placing patient so that their center of gravity is close to yours will make the biomechanics of the technique easier and allow you to use your arms and torso to support the patient.
- Place finger pads under the anterior costal margin and contact the diaphragm.
- Assess where the greatest area of restriction is. The restriction may be in the mediastinum or the lumbar spine.
- Expand your anatomical awareness and try to think in 3 dimensions.
- Use the patient’s torso to place them into the barrier (direct) or position of ease (indirect).
- Use MFR principles to resolve the somatic dysfunction.
Still Technique
- Place the dysfunctional tissues into their position of ease.
- Add a force vector (usually compression) through the dysfunctional tissues.
- Move the tissues through the restrictive barrier.
- It works better to correct the saggitalplane last.
Still Technique for the First Rib(seated)
INHALED
Brace opposite hand on the table with the elbow locked in extension.
Hand on affected side is placed on the anterior chest.
Place medial hand on rib head to monitor it. The forearm becomes a fulcrum as the technique progresses.
Lateral hand applies a compressive vector force from the elbow to the rib head to decrease tension on the joint capsule.
Lift the elbow cephalad while maintaining the compressive force throughout the arc.
This mimics the “up in front” position of the inhaled rib
Continue moving the elbow cephalad and then posteriorly while maintaining the compressive force.
As you move the elbow posteriorly and inferiorly, the rib head is now pushed through the physiologic barrier.
You may feel it “clunk” back into place.
Recheck to ascertain resolution of the somatic dysfunction.
Still Technique for the First Rib(seated)
EXHALED
Place medial hand on rib head to monitor it.
Lateral hand applies a compressive vector force from the elbow to the rib head to decrease tension on the joint capsule.
Place medial hand on rib head to monitor it.
Lateral hand applies a compressive vector force from the elbow to the rib head to decrease tension on the joint capsule.
Lift the elbow cephalad while maintaining the compressive force throughout the arc.
This mimics the “up in back” position of the exhaled rib.
Continue lifting the elbow cephalad and swing it anteriorly while maintaining the compressive force throughout the arc.
This mimics the “up in back, down in front” position of the exhaled rib.
As you move the elbow superiorly and anteriorly, the rib head is now pushed through the physiologic barrier.
You may feel it “clunk” back into place.
Recheck to ascertain resolution of the somatic dysfunction.
Still Technique for Thoracic and Lumbar Vertebral Somatic Dysfunction(seated)
- Check for area of greatest restriction.
- Identify the SD within the AGR.
- Can use head & neck as a lever for treating upper Tswith compressive force coming from top of head, through neck to SD.
- For lower Tsand Ls, place your hand on one of the patient’s shoulders and your opposite axilla on the other shoulder. Compress from both shoulders to the level of the SD.
- If there are multiple SDs, treat the worst one first. Place it in the position of ease and then quickly check the other SDs. If they are not apparent, don’t treat them. They are compensatory SDs.

STILL TECHNIQUE for RIBS
inhaled
- Rib(s) held in inhalation are more anterior and move more freely anteriorly.
- Rotation of the thorax anteriorly to the opposite side of the affected rib should put the tissues into ease.
- Hold the posterior portion of the rib to move it anteriorly.
- Rotate the ipsilateral shoulder anteriorly to the opposite side.
- Add compression with your hand on the shoulder (and your axilla on the other shoulder).
- Return the ipsilateral shoulder posteriorly.
STILL TECHNIQUE for RIBS
exhaled
- Rib(s) held in exhalation are more posterior and move more freely posteriorly.
- Rotation of the thorax posteriorly to the opposite side of the affected rib should put the tissues into ease.
- Hold the anterior portion of the rib to move it posteriorly.
- Rotate the ipsilateral shoulder posteriorly to the opposite side.
- Add compression with your hand on the shoulder (and your axilla on the other shoulder).
- Return the ipsilateral shoulder anteriorly.

- Paraneoplasticsyndromes (intrathoracictumors)
Hypertrophic osteoarthropathy from bronchogenic carcinoma causes
clubbing of the fingers and toes and a polyarthritis that resembles rheumatoid arthritis – knees, ankles, and wrists are most commonly affected
Adult Muscle and Skin Involvement
cancer
- Tumors can metastasize to muscles and cause pain and decreased function due to muscle or nerve compression
- These masses may be small and deep-seated
- Dermatomyositisand polymyositishave a progressive proximal muscular weakness and is associated with lung and gastric cancer 50% of the time
- Acanthosisnigricansis associated with gastric or abdominal malignancies
Dermatomyositis and polymyositis may precede a malignancy by
days or years – skin manifestations include a purplish erythema – dx via muscle bx, increased ESR and muscle enzymes, and abnormal EMG.
Acanthosis nigricans – hyperpigmented, hyperkeratotic skin lesion in the flexor areas of axillary, neck, or anogenital areas is assoc with gastric or abd malignancies
Pediatric Cancer Incidence
•Leukemias(26.5%) –Acute lymphoblastic leukemia (19%) •CNS tumors (17.7%) •Lymphomas (14.6%) •Other (10.3%) –Thyroid (4%), melanoma (3.4%) •Soft tissue sarcoma (7%) •Germ cell (6.4%) •Bone tumor (5.3%) •Neuroblastomas(4.8%) •Renal tumor (3.9%)
Leukemia
may present with bone pain secondary to marrow hyperplasia as well as fatigue, pallor, ecchymoses, infection, fever, anorexia, weight loss
Extremity lesions present with pain subsequent to trauma but the trauma may not be causing the pain
CNS tumors often present with a headache in addition to ataxia and gait abnls, seizures or cranial nerve palsies – look for history of a headache while sleeping and absence of a family hx of migraines
Sudden onset of back pain that worsens when supine – may need an MRI
Neuroblastomas – most common extracranial solid tumor of childhood – paraspinal tumors may extend into the neural foramina and cause signs and symptoms of nerve root or spinal cord compression – bone mets very common esp skull
Pediatric Cancer
•Malignant musculoskeletal tumors account for approximately 12% of malignant neoplasms of childhood
•Most common are:
–Osteosarcoma–during puberty, around the knee
–Ewing’s sarcoma
–Rhabdomyosarcoma
•Pain is the most common presenting symptom
Pediatric Cancers –Bone Metastases
- Neuroblastoma
- Wilmstumor
- Osteosarcoma
- Ewing sarcoma
- Rhabdomyosarcoma
account for more than 60% of childhood cancers
Leukemia, bone tumors, neuroblastomas can cause bone or muscle pain
history for onc
- Previous cancer dxand tx
- Dxevalfor cancer
- Occupational and exposure history
- Signs/symptoms specific to the 5 organs from which bone metscommonly arise
Bone Metastases Incidence
- Cancer causes less than 1% of back pain in the general population
- 98% of known cancer patients who present with back pain have underlying metastases
- Up to 1/3 of patients with cancer develop metastases to the spine
need to aggressively investigate bone pain in cancer pts because
they could destabilize the axial skeleton and encroach upon the spinal cord or cauda equina
Bone Metastases
- Pain is the most common presenting symptom
- Localized, constant bone pain is the hallmark
- Often begins as dull and intermittent but worsens steadily, often over several days or weeks
- Pain at night and at rest is common
- Common sites are the vertebral column (espthorax), skull, humerus, ribs, pelvis,
Potential for pathologic fracture if pain with weight-bearing
Requires radiographic and laboratory evaluation
Bone scan may be needed to find occult lesions
bone metasteses red flags
- Unexplained musculoskeletal pain
- Pain in spine or proximal extremities (hips, thighs, shoulders) that doesn’t correlate with a known injury
- Night or rest pain
bone metastasis pain referral patterns
- High cervical spine mets–posterior headache
- C7-T1 –interscapularpain
- T12-L1 –flank, iliac crest, or sacroiliac joint
- Sacral destruction –saddle distribution
physical exam for cancer
- Differentiate between bone and joint pain
- If passive motion of the adjacent joint isn’t painful then be more alert to a cancer possibility
- Specific exam of the common neoplasticprimary sites
Imaging Studies for cancer metastasis
- Plain film radiography is the most specific for metastatic disease –will detect 70% of vertebral tumors
- Obtain radiograph of the entire long bone for all painful sites
- Multiple lesions are characteristic of metastatic disease
- Lytic: lung, thyroid, kidney
- Blastic: prostate
- Mixed: breast, cervical, testicular, ovarian
- Bone scan should be done if there is lesion on xrayor on a pt with a known primary cancer and negative xray
- CT scan of the chest, abdomen, and pelvis to look for primary cancer
The metastases may occur in any bone
but most involve the axial skeleton (vertebral column, pelvis, ribs, skull, sternum), proximal femur, and humerus, in descending order of frequency. The red marrow in these areas with its rich capillary network, slow blood flow, and nutrient environment facilitates implantation and growth of the tumor cells. Metastases to the small bones of the hands and feet are uncommon and usually originate in cancers of the lung, kidney, or colon.
(Kumar, Vinay. Robbins & Cotran Pathologic Basis of Disease, 7th Edition. Saunders Book Company, 082004. 26.1.2.6.3).
Carefully inspect xrays for the type and extent of disease, presence of multiple lesions within the same bone, and the involvement of adjacent joints.
