COMLEX Level 3 key terms

A palpable impairment of related components of the somatic system: the musculoskeletal, arthrodial, and myofascial structures and their vascular, lymphatic, and neural elements. Diagnosed by TART findings and treated with osteopathic manipulative treatment.

The four diagnostic findings of somatic dysfunction: tissue texture abnormality, asymmetry of position or motion, restriction of motion, and tenderness to palpation. All four are documented in the somatic dysfunction diagnosis and reassessed after treatment.

A set of hands-on techniques used by osteopathic physicians to diagnose and treat somatic dysfunction, improve physiologic function, and support homeostasis. Techniques include soft tissue, myofascial release, muscle energy, counterstrain, high-velocity low-amplitude, and lymphatic and cranial methods.

A direct thrust technique that uses a rapid, low-amplitude force applied at a restrictive barrier after positioning the patient to localize the barrier. A pop may occur but is not required for success. Avoid in osteoporosis, fracture, malignancy, or unstable joints.

An osteopathic technique in which the patient voluntarily contracts a muscle from a controlled position in a specific direction against a distinct physician counterforce. Used to lengthen restricted muscles, mobilize joints, and improve lymphatic drainage via post-isometric relaxation.

An indirect osteopathic technique that places the patient in a position of greatest comfort by shortening the offending muscle, then holds that position for about 90 seconds to reduce tenderness at a monitored tender point. Also called strain-counterstrain.

The point in a joint's range of motion at which further movement is limited by a somatic dysfunction. It lies short of the anatomic barrier; treatment aims to restore motion toward the physiologic barrier.

The limit of active motion a person can achieve voluntarily. It lies between the restrictive and anatomic barriers and is used as a reference point for diagnosing and grading motion restriction.

The hard limit of motion imposed by bones, ligaments, and joint capsules beyond which movement would injure tissue. It represents the absolute end range and is never forced during treatment.

A small, firm, tender nodule found in the deep fascia or muscle, used as a neurolymphatic reflex marker for visceral or glandular dysfunction. Treated with circular pressure or soft tissue massage.

A reflex in which visceral dysfunction produces somatic changes such as muscle spasm, tenderness, or vasomotor changes in the segmentally related spinal region. Identified by segmental TART findings that may resolve when the visceral problem is treated.

A spinal cord region in which repeated or sustained afferent input lowers the threshold for neuronal firing, causing exaggerated reflex responses. It explains how somatic dysfunction can perpetuate pain and autonomic changes.

A gentle osteopathic approach that palpates the primary respiratory mechanism, including cranial rhythmic impulse, and applies light force to treat restrictions in the cranial vault, sacrum, and connected structures. Evidence is limited; use judgment about indications.

A rhythmic compression and release of the thorax or abdomen, such as the thoracic or pedal pump, that promotes venous and lymphatic return. Used in edema, lymphedema, and respiratory congestion; avoided in acute infection or embolism risk.

Conditions in which manipulative treatment could cause harm, including acute fracture, unstable joint, malignancy at the site, severe osteoporosis, suspected aortic aneurysm, and acute infection. Relative contraindications require modified technique or deferral.

An osteopathic approach in which the physician moves the affected region into the restrictive barrier and applies force to correct the dysfunction. Muscle energy and HVLA are examples; contrast with indirect technique.

An osteopathic approach in which the physician moves the affected region away from the restrictive barrier, following the path of least resistance, and waits for release. Counterstrain and functional methods are examples.

Palpatory assessment of active, passive, and regional range of motion to identify asymmetry and restriction. Findings guide the choice of technique and provide a baseline for reassessment after treatment.

A discrete, exquisitely tender spot within a taut band of muscle, often reproducing the patient's pain. Distinct from a trigger point by location and from fibromyalgia tender points by diagnostic context; treated with counterstrain or spray-and-stretch.

A soft-tissue technique that applies sustained gentle traction or pressure to fascial planes to release restrictions and restore motion. Often used as a direct or indirect method depending on the direction of force.

The reduction in muscle tone and increased length that follows a brief voluntary isometric contraction. It is the physiologic basis for muscle energy technique and explains why treatment is comfortable and effective.

A systematic regional assessment of the musculoskeletal system for somatic dysfunction, including posture, symmetry, motion, and tissue texture. It is documented in the medical record and repeated to evaluate treatment response.

The process of explaining a proposed intervention, its risks, benefits, and alternatives, and confirming the patient's voluntary agreement. Required for procedures and OMT, and documented in the record.

A collaborative process in which the physician presents evidence-based options and the patient's values and preferences guide the choice. It improves adherence and is central to patient-centered osteopathic care.

A directive, patient-centered counseling style that explores and resolves ambivalence about behavior change using open questions, reflective listening, and affirmation. Effective for smoking cessation, substance use, and weight management.

The degree to which a patient can obtain, process, and understand health information needed to make decisions. Low health literacy increases medication errors and readmissions; use teach-back and plain language to address it.

A communication technique in which the patient explains the plan in their own words to confirm understanding. It detects gaps in comprehension and is recommended for discharge instructions and high-risk medications.

Qualified language professionals who facilitate communication with patients of limited English proficiency. Use of trained interpreters, not family members, is legally required in many settings and improves accuracy and confidentiality.

A lifelong process of self-reflection and openness to patients' cultural identities, values, and beliefs, combined with recognition of power imbalances. It supports respectful communication and reduces bias in clinical decisions.

Unconscious attitudes or stereotypes that affect judgments and behavior, including clinical decisions. Recognizing and mitigating bias through structured assessment and reflection supports equity and professionalism.

A patient's ability to understand information, appreciate the consequences of a decision, reason through options, and communicate a choice. Capacity is decision-specific and assessed clinically, unlike legal competence.

A legal document stating a patient's preferences for future care, such as a living will or durable power of attorney for health care. It guides decisions when the patient lacks capacity.

The ethical principle that patients have the right to make informed decisions about their own care, including refusing treatment. It grounds informed consent and confidentiality obligations.

The principle that all people should have fair access to the highest attainable health, requiring removal of structural barriers and disparities. Physicians address it through screening, advocacy, and equitable resource use.

Conditions in which people are born, grow, work, and age, including income, housing, education, and food security, that shape health outcomes. Screening for them informs treatment plans and referrals.

The deliberate organization of patient care activities among participants to facilitate appropriate, timely, and efficient care. Includes transitions of care, referral management, and communication among providers.

The movement of a patient between care settings, such as hospital to home or skilled nursing facility. Medication reconciliation and clear handoffs reduce readmissions and adverse events.

A structured process of comparing a patient's current medication list with new prescriptions across transitions to prevent omissions, duplications, and dosing errors. It is a core patient-safety practice.

An injury caused by medical management rather than the patient's underlying disease, which may be preventable or nonpreventable. Reporting and root-cause analysis support system improvement.

A structured team method to identify underlying system failures that contributed to an adverse event and to design corrective actions. It focuses on processes rather than individual blame.

A systematic approach to improving care using models such as PDSA cycles, measurement, and iterative change. It relies on data and team-based problem solving to close performance gaps.

Plan-Do-Study-Act, a rapid-cycle improvement method in which a change is tested on a small scale, evaluated, and then adapted or adopted. It is the core tool of many quality improvement projects.

Comparing a practice's performance metrics against internal or external standards to identify gaps and set improvement goals. It supports evidence-based practice and accountability.

The integration of best available research evidence, clinical expertise, and patient values in decision-making. It emphasizes critical appraisal of study design and applicability to the individual patient.

A hierarchy ranking study designs by susceptibility to bias, from systematic reviews and randomized controlled trials down to case reports and expert opinion. It guides the strength of clinical recommendations.

The number of patients who must receive an intervention for one additional patient to benefit, calculated as 1 divided by the absolute risk reduction. Lower values indicate greater clinical benefit.

Systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific circumstances. Guidelines are not mandates and should be applied with clinical judgment.

The prevention of harm to patients through systems design, error reporting, and continuous learning. It includes hand hygiene, checklists, and safe medication practices.

The health outcomes of a group of individuals, including the distribution of outcomes within the group. It informs prevention, screening, and resource allocation across a community.

The contemporaneous, accurate record of history, examination, assessment, and plan, including procedures and patient education. It supports continuity, billing integrity, and legal defensibility.

The set of behaviors reflecting honesty, integrity, respect, accountability, and commitment to patient welfare. It includes managing conflicts of interest and maintaining appropriate boundaries.

The transtheoretical model describing readiness to change: precontemplation, contemplation, preparation, action, and maintenance. Interventions are matched to the patient's stage to reduce resistance and support progress.

The systematic evaluation of a study's validity, results, and relevance to a clinical question. It includes assessing bias, confounding, and generalizability before applying findings.
