1 Neuro Rehabilitation Toolbox Roadmap Introductions Framework for classifying tests and measures Tests and measures by clinical setting Patient case Wrap up California Physical Therapy Association Annual Conference 2011 D. Michael McKeough, PT, EdD Professor of Physical Therapy California State University Sacramento Learning Objectives At the completion of this presentation, participants will be able to: Describe influence of disablement models of the selection of tests/measures Compare and contrast Nagi and ICF models of disablement Describe the characteristics of good tests and measures Select good tests/measures based on your conceptual model of clinical practice, outcome goals, patient characteristics, and clinical setting Develop basic familiarity with commonly used, valid, reliable and sensitive measures of body function and structure, activity, and participation Framework We are here to talk about neuro rehabilitation tests and measures (outcome measures, OM) What tests you select depend on your objectives Your objectives depend on what you choose to examine and what you choose to treat What you choose to examine/treat depends on your conceptual model of clinical practice Conceptual Framework For Clinical Practice APTA Model of Physical Therapy Practice 1. Model of PT Practice APTA model defines PT practice 2. Model of Disablement Describes how a patient becomes disabled 3. Hypothesis Oriented Clinical Practice Describes PT clinical reasoning 4. Theory of Motor Control Describes leading theories of how movement is controlled Evaluation Examination Diagnosis Outcomes Prognosis Intervention (Shumway Cook and Woollacott 2007) Patient Centered Care Guide to Physical Therapist Practice

2 Disablement Model How a person became disabled A conceptual explanation of the process and underlying mechanisms by which h disease, injury or birth defect impacts a person s ability to function (perform their expected role in society). Level of Analysis Cell / Organ (Arrest pathology, cell protection) [Change risk factors] System (Motor, sensory, cognitive) [ROM, strength, th pain] Person (Activities of daily living) [Mobility, gait, balance] Society (Work, culture, leisure) [Return to work/leisure] Nagi Model Primary Pathology Primary Impairment Functional Limitations Disability Nagi 1965 Hypothesis Oriented Clinical Practice Clinical reasoning Chart driven (novice clinical reasoning) Follow chart driven examina on from Q1 Qn Hypothesis oriented (expert clinical reasoning) Make an observation, then formulate an hypothesis about its cause Evaluate the hypothesis (cause) by conducting a test Level of Analysis Cell / Organ (Arrest pathology, cell protection [Change risk factors] System (Motor, sensory, cognitive) [ROM, strength, th pain] Person (Activities of daily living) [Mobility, gait, balance] Society (Work, culture, leisure) [Return to work/leisure] Nagi Model Primary Pathology Primary Impairment Functional Limitations Disability Nagi 1965 Limitations of Nagi Model Nagi is a unidimensional (pathology based) and unidirectional model of disability only Does not account for impairments and functional limitations not due to pathology Functional limitations due to lifestyle (obesity, diabetes) Disability due to environmental barriers or personal factors Theory What is done with a theory that fails to account for experimental observations (data) or has too many limitations? It is replaced by a new theory that does account for the data. 2

3 International Classification of Functioning, Disability and Health (ICF) The World Health Organization (WHO) authorized the International Classification of Functioning, Disability and Health (ICF) in Goes beyond disability to include functioning, health and disability Includes non pathological causes of functional limitations and impairments Context variables: potentially have effect on all levels of model It is accepted by more than 200 countries as the international standard to describe and measure health and disability. Nagi Model International Classification of Functioning, Disability and Health (ICF) Impairment Functional Limitations Disability Contextual Variables (WHO, 2002) Conclusion Nagi is a unidimensional (pathology based) and unidirectional model of disability ICF is multidimensional (bio psycho social) and multidirectional model of human health Affords opportunity to formulate multiple alternative hypotheses about the cause of the functional limitation Hypothesis Testing (Characteristics of Good Tests and Measures) Requires valid, reliable, and sensitive measures Validity Measures what it purports to measure Reliability Proper use of the instrument produces stable outcomes (Inter and intra rater reliability) Sensitivity / Responsiveness Capable of detecting change (MDC, MCID) Ceiling and floor effects Minimum Detectable Change (MDC) Reliable change or smallest real difference (Ottenbacher 1988) (MDC = SEM x Z x 2) Smallest change in score that likely reflects true change rather than measurement error (Stratford 1996) Minimal Clinically Important Difference (MCID) Magnitude of change required to produce a meaningful improvement in performance Smallest difference in a measure that is considered worthwhile or important MCID scores have limited generalizability, so they should be used only with patients having characteristics similar to those of the subjects for which MCID were reported (Haley 2006) 3

4 Continuum of Change Responsiveness r error Threshold fo Real but unimportant change Important Change Threshold for No change MDC MCID Continuum of Change Real and important change Large change Ceiling effects Level above which variance in performance is no longer measured FIM does not detect improvement in ambulation beyond d150 Floor effects Level below which performance cannot be measured HiMAT is incapable or assessing improvement in ambulation < 20m (Beninato 2011) Evidence based Practice (EBP) Outcome measures are a critical part of EBP Recent evidence suggests that the use of OMs in clinical practice is limited (Jette 2009, Kay TM, 2001, Huijbregts 2002) Selecting the most appropriate OM enhances clinical practice by: Identifying and quantifying body function and structure limitations Formulating the evaluation, diagnosis, and prognosis Informing the plan of care Helping to evaluate the effectiveness of physical therapy interventions Barriers to Use of OM Time constraints Difficult for patients to complete Lack of equipment Knowledge regarding OMs (Jette 2009, Van Peppen 2008, Kay 2001) How to select and apply the best OM (Huijbregts 2002) Tests and Measures by Practice setting StrokEDGE Taskforce 2011 Tests and Measures by Practice setting Acute Care In Patient and Out Patient Home Health Skilled Nursing Facility Entry Level Education 4
