ABPTS PWCS key terms

An involuntary movement pattern present in early infancy that typically integrates as the nervous system matures. Persistence beyond the expected age can signal neuromotor delay and prompt further developmental screening.

The background level of muscle tension that supports upright posture and movement against gravity. Both excessively low and excessively high tone interfere with typical motor skill acquisition.

A functional skill most children acquire within an expected age range, such as sitting or walking. Clinicians compare attainment timing against norms to detect delay or deviation.

Chronologic age adjusted for prematurity by subtracting weeks born early from the infant's current age. It is used when judging developmental expectations until roughly two years of age.

Slower-than-expected acquisition of large movement skills such as rolling, sitting, or walking. It often triggers referral for physical therapy evaluation and monitoring of progression.

A nonprogressive group of movement and posture disorders caused by early brain injury or maldevelopment. Presentation varies by motor type and distribution and often includes associated sensory and communication impairments.

Velocity-dependent increase in muscle resistance to passive stretch arising from altered central nervous system control. It can limit range of motion and complicate handling during therapy.

Reduced resting muscle tension that makes movement feel floppy and requires greater effort against gravity. It is a sign rather than a diagnosis and warrants investigation of underlying causes.

The nervous system's capacity to reorganize connections and function in response to experience, practice, and injury. It underpins early intervention and task-specific training in pediatric rehabilitation.

A developmental window during which the nervous system is especially responsive to certain types of experience. Timing considerations influence how early intervention is prioritized.

A test administered and scored according to fixed procedures with established reference data. Results support comparison to peers and documentation of change over time.

A score expressing a child's performance relative to a comparison group, often as a standard score or percentile. Interpretation depends on the adequacy of the normative sample for the child being tested.

An assessment that compares performance to a defined skill standard rather than to other children. It is useful for identifying specific functional gaps and setting intervention goals.

The consistency of an assessment's results across occasions, raters, or items. Low reliability limits confidence in individual scores and in detecting real change.

Sensitivity is the proportion of children with a condition correctly identified by a test; specificity is the proportion without it correctly cleared. Both inform screening and diagnostic decisions.

Brief, low-cost procedures used to flag children who may need fuller evaluation. Positive results indicate need for further testing, not a confirmed diagnosis.

The extent of movement available at a joint, measured actively or passively. Restricted motion in children can reflect tone, contracture, or pain and guides stretching and positioning choices.

The extensibility of a muscle-tendon unit across a joint. Assessing length helps distinguish tightness from weakness when planning stretching or orthotic support.

Systematic observation or instrumented measurement of walking patterns, including timing, symmetry, and joint motion. Findings inform orthotic, strengthening, and training decisions.

A reasoned prediction of the likely course and outcome of a child's condition. It integrates diagnosis, current function, age, and environmental supports and is revised as data accumulate.

A method that defines individualized, measurable levels of achievement for a specific goal, from less than expected to more than expected. It captures change meaningful to the family.

The smallest change in a measure's score that exceeds measurement error with a stated confidence. Change smaller than this threshold cannot be confidently attributed to intervention.

The relatively permanent change in movement capability resulting from practice and experience. Principles such as variability, feedback, and repetition shape pediatric intervention design.

Practice of functional activities that closely resemble the real-world skill being targeted. It supports transfer of learning better than isolated exercise alone in many pediatric populations.

An approach that treats the family as a partner in assessment, goal setting, and intervention. It respects family priorities, culture, and routines when designing services.

Voluntary agreement to evaluation or treatment given after disclosure of purpose, risks, benefits, and alternatives. In pediatrics it typically involves parental permission plus child assent as appropriate.

The professional obligation to protect a patient's private health information from unauthorized disclosure. Exceptions and permitted sharing are governed by law and organizational policy.

Deliberate organization of activities among providers, families, and agencies to deliver coherent services. It reduces duplication and supports transitions across settings.

The boundaries of services a clinician is legally and professionally authorized to provide. Exceeding them creates risk and may violate licensure or regulatory rules.

The ability to evaluate and treat patients without a prior physician referral, as permitted by state law. Conditions and limits vary by jurisdiction and setting.

Oversight provided by a qualified clinician to assistants, students, or others with restricted authority. Requirements for frequency and documentation are set by regulation and payer policy.

A hierarchy ranking study designs by their vulnerability to bias, from systematic reviews down to expert opinion. It guides how much confidence to place in a given finding.

Systematic judgment of a study's validity, results, and applicability to a clinical question. It separates trustworthy findings from those limited by design or analysis flaws.

Clinical decision making that integrates the best available research with clinician expertise and patient and family values. It treats evidence as one input rather than a rigid rule.

Structured, iterative efforts to measure and improve processes and outcomes within a practice setting. Methods typically include aim setting, data tracking, and small tests of change.

A tool used to quantify a patient's status or change in status over time. Selection depends on the construct targeted, responsiveness, and feasibility in the setting.

Cooperative work among professionals from different disciplines who share goals and responsibilities for a patient. It improves continuity and reduces conflicting recommendations.

The degree to which a person can obtain, process, and understand health information needed to make decisions. Instruction should be adapted to the family's demonstrated understanding.

A communication technique in which the learner explains information in their own words to confirm understanding. It reveals gaps that simple questioning may miss.

An ongoing self-reflective stance that recognizes one's own biases and the limits of cultural knowledge. It supports respectful adaptation of care to each family's context.
