OMM Fundamentals: From Examination to Treatment Choice
Learn to interpret TART findings, name spinal dysfunction, distinguish treatment barriers, and choose osteopathic techniques with sound clinical reasoning.
A right transverse process feels posterior. That finding describes rotation, but it does not yet identify flexion or extension, explain the patient's pain, or select a treatment. Fundamentals become useful when each observation answers a different question: what is abnormal, which direction is easier, and what intervention fits this person?
Start with the person and the clinical problem
Osteopathic medicine treats the person as an integrated whole. The four tenets connect body, mind, and spirit; recognize capacities for regulation and recovery; connect structure with function; and place rational treatment within those relationships. They are principles for clinical reasoning, not a promise that every illness can resolve through manipulation. Medication, surgery, rehabilitation, and prevention can all belong in osteopathic care. A person with back pain may need a structural examination and an assessment of sleep, work demands, mood, and neurologic symptoms. [1]
Five commonly taught models help organize that assessment. The biomechanical model asks about load, posture, and restricted motion. The neurologic model considers pain processing and autonomic or motor function. The respiratory and circulatory model considers breathing and fluid transport. The metabolic and energy model considers illness burden, nutrition, and the demands of recovery. The behavioral model considers habits, stress, goals, and social circumstances. These perspectives overlap; they do not require five separate treatments. [2]
Before palpation, identify a useful clinical goal. Comfortable neck rotation while driving is more informative than simply obtaining a different palpatory finding. Establish consent for the examination and proposed technique, including the patient's ability to stop. Assess symptoms that require another pathway, such as new weakness, saddle sensory loss, urinary retention, fever with spinal pain, or substantial trauma. A somatic finding can coexist with serious disease. It does not settle that differential diagnosis.
Describe findings before assigning a cause
Somatic dysfunction describes altered function involving the musculoskeletal framework and related tissues. TART provides four categories: tissue texture abnormality, asymmetry, restriction of motion, and tenderness. An examination may support the diagnosis without all four being present, but tenderness alone has many possible causes. A tender vertebra after a fall deserves consideration of fracture. Tender paraspinal tissue during visceral illness may reflect associated somatic changes. Neither finding supplies its own explanation. [2]
Observe posture and skin first, then palpate with graded pressure and compare corresponding regions. Assess regional active motion before using gentle passive and segmental testing where appropriate. Record the actual side, level, tissue response, and directional limitation. “Right T6 paraspinal tenderness with reduced left rotation” is reproducible information; “the back is out” is not. Static asymmetry is a starting observation. Position, normal anatomical variation, and examiner pressure can all affect it.
Texture patterns are tendencies, not a clock or a tissue biopsy

Skin drag and a red response after stroking are nonspecific observations. They do not establish the age of a lesion, demonstrate new blood vessels, or distinguish every visceral from musculoskeletal cause. “Compensated” and “uncompensated” describe adaptation within a broader examination; they are not reliable synonyms for painless chronic and painful acute tissue. Reassessment should include the patient's function as well as the signs the examiner can feel.
Separate direction, participation, and force
A barrier is a limit to motion. The physiologic barrier is the limit of active motion. Passive assessment may reveal an additional elastic range before the structural limit called the anatomic barrier. A restrictive barrier occurs earlier than expected. It can change with somatic dysfunction, while structural disease can impose a more fixed limitation. A diagram of these concepts is not permission to push a joint to its anatomic limit. Pain, instability, guarding, and tissue quality can require stopping much sooner. [2]
One direction of motion, from the present position outward
Restricted joint
Present position → early restrictive barrier
Conceptual normal range
Present position → active limit → additional passive elastic range → structural limit
Direct approach
Engage the identified restrictive barrier with a suitable technique
Indirect approach
Position away from that restriction toward greater ease
Distances are schematic. No universal shoulder angle defines safe treatment, and the structural limit is not a treatment target.
Direct and indirect describe the relationship to the restrictive barrier. Active and passive describe the patient's role. In an active technique, the patient contributes voluntary muscular effort; in a passive technique, the clinician supplies the positioning or force while the patient relaxes. These are independent distinctions. A direct technique need not involve a thrust, and an indirect technique is not automatically appropriate for fragile or unstable tissue.
High velocity, low amplitude treatment is generally direct and passive: a carefully limited impulse is applied after a suitable setup. Muscle energy is generally direct and active: the patient contracts against a precisely directed counterforce. Counterstrain is indirect and passive: a monitored tender point becomes more comfortable through supported positioning. Facilitated positional release is also commonly indirect and passive. Myofascial release can engage resistance or follow ease. Cranial techniques can use direct or indirect principles. Lymphatic pumps and Chapman point treatment involve clinician-applied forces, but their names alone should not force every application into a simplistic four-box classification. [2]
Use anatomy to name the position of ease
The spine has seven cervical, twelve thoracic, and five lumbar vertebrae above the sacrum. Cervical and lumbar curves are lordotic; thoracic and sacral curves are kyphotic. These are normal regional shapes, not diagnoses by themselves. Facet orientation contributes to regional motion: typical cervical facets are oblique, thoracic facets are predominantly coronal, and lumbar facets are predominantly sagittal with superior facets facing medially. The upper cervical joints have specialized anatomy. The atlantoaxial region contributes substantially to cervical rotation, so “the thoracic spine rotates most” is an unreliable whole-spine rule. [3]
Vertebral rotation is named for the vertebral body's orientation. When the right transverse process is posterior relative to the left, the body is rotated right in the usual segmental model. Compare that asymmetry during flexion and extension. If it diminishes in extension and becomes more evident in flexion, extension is the position of ease. Add independently assessed sidebending before completing the diagnosis. Do not infer every component from one static contact. [4]
Worked spatial comparison: T6 has a posterior right transverse process. The asymmetry improves in extension, and right sidebending is easier. Name it T6 extended, rotated right, sidebent right, or T6 ERS right. An indirect setup follows extension, right rotation, and right sidebending. A direct setup engages the restrictions toward flexion, left rotation, and left sidebending, within the technique's safe range.
Fryette's first principle describes neutral thoracolumbar coupling, usually a group pattern, with rotation and sidebending in opposite directions. The second describes nonneutral coupling, commonly a single segment, with rotation and sidebending in the same direction. The third describes how introducing motion in one plane alters or limits motion available in other planes. These are osteopathic models for interpreting an examination, not universal equations that override the observed patient. Regional anatomy, starting position, and loading matter. Cervical diagnosis uses regional conventions and should not be reduced to a neutral lumbar rule. [2][4]
Match muscular effort and treatment to the goal
An isometric contraction produces force without an appreciable change in muscle length. In an isotonic description, muscle length changes against an approximately constant load. Concentric contraction shortens an active muscle; eccentric contraction lengthens it while it remains active, as when lowering a weight under control. Eccentric does not mean relaxed. In an isolytic application, the clinician's force exceeds the patient's opposing effort and produces controlled lengthening. This terminology does not establish that adhesions were torn or fibrosis was corrected. [2]
Muscle energy commonly uses a gentle isometric effort, followed by relaxation and reassessment before another engagement of the barrier. Other contraction arrangements exist. More effort is not inherently more effective, and exhausting a painful muscle is not the defining objective. Clear instructions about direction and intensity matter more than the patient's willingness to push hard. A patient unable to understand or provide the required contraction may need a different approach.
Technique selection depends on tissue integrity, the examination, tolerance, and consent. A suspected fracture, local metastatic bone lesion, or major instability rules out thrust treatment through that region. Rheumatoid disease can involve cervical instability; the diagnostic context matters before cervical positioning. A passive approach still needs screening. If a patient declines a thrust, discuss an acceptable alternative or omit manipulation. Consent to evaluation is not blanket consent to every technique.
Choose an order that permits useful reassessment. Thoracic treatment before a mechanically related rib treatment may clarify what restriction remains. It is not an absolute rule that every proximal segment must be treated before every distal one. Following any intervention, recheck the relevant motion and symptom, ask about adverse effects, and compare the functional goal with baseline. Document what changed and what did not. Persistent or worsening findings should prompt reconsideration of the diagnosis, rather than an automatic increase in force or a longer list of techniques.
Apply the examination findings
Each scenario asks for one interpretation or decision. Distinguish a named position of ease from a treatment setup, and distinguish a structural finding from a complete clinical diagnosis.
Case 1
Show answer and explanations for case 1
A. Treat the cervical finding as sufficient to explain the poor sleep. (Why this does not fit)
The examination supports a regional dysfunction, but it does not establish the cause of the sleep problem.
B. Exclude medication or rehabilitation because treatment must be manual. (Why this does not fit)
The tenets support comprehensive care; they do not restrict treatment to manipulation.
C. Defer all physical examination until the stress resolves. (Why this does not fit)
Stress does not eliminate the need to assess the reported neck symptoms.
D. Address cervical function together with sleep, work demands, and the patient's goals. (Best answer)
The mechanical finding and the circumstances affecting recovery both matter in this driver's care.
Takeaway: Whole-person care integrates relevant mechanisms and patient priorities.
