In the absence of a gold standard , construct validation occurs, where theories about the attribute of interest are formed, and then the extent to which the measure under investigation provides results that are consistent with these theories are assessed. The scoring criteria were discussed and revised until the task force reached unanimous agreement. Inter-rater: (1999). Xiao Y, Luo Q, Yu Y, Cao B, Wu M, Luo Y, Zhao Y, Zhou J. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. of the TUG in 50 individuals with strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. Dallas, TX 75231 The advantage of the former is mainly related to the need to assess balance in each patient with a stroke, irrespective of the severity of impairment. measures indicate normal performance). This book will provide an invaluable reference manual for those who want to take research on mental health services, and for those who need to interpret this research for policy, planning, and clinical practice. These are also referred to as function. This site needs JavaScript to work properly.
Note: Caution should be taken in interpreting these findings as the Spearman correlationThe extent to which two or more variables are associated with one another. Background and Purpose—Few clinical tools available for assessment of postural abilities are specifically designed for stroke patients. The score consists of the time taken to complete the test activity, in seconds. Adequate correlations with the Barthel Index, Functional Independence Measure, Groningen Activity Restriction Scale, Sickness Impact Profile. Gait is a complex activity that relies on navigation and rhythmic motor activity of the 2 lower limbs and requires a good balance. Am J Phys Med Rehabil. The correlationThe extent to which two or more variables are associated with one another.
= 1.02). Given the simplicity of the instructions, the TUG can be administered in different languages with informal translations (Tremblay, Savard, Casimiro, & Tremblay, 2004). Three experienced clinicians and 3 inexperienced clinicians later rated the videotape. No significant difference was found between the two raters (mean difference = 0.04s).
Podsiadlo and Richardson (1991) found that the TUG demonstrated excellent intra-rater reliabilityThis is a type of reliability assessment in which the same assessment is completed by the same rater on two or more occasions. This correlation is called the “effect size correlation”. There are a wide variety of methods for measuring correlation including: intraclass correlation coefficients (ICC), the Pearson product-moment correlation coefficient, and the Spearman rank-order correlation. Objective.
Sitting without support (sitting on the edge of an 50-cm-high examination table [a Bobath plane, for instance] with the feet touching the floor), 1=can sit with slight support, for example, by 1 hand, 2=can sit for more than 10 seconds without support, 2. Construct validity, ie, the extent to which the PASS can be related to other constructs, was assessed by an examination of how it correlated with clinical indexes (motricity, somatosensory threshold, spatial inattention, spasticity, and functional status) and with instrumental measures of sitting balance, when available.
A literature search was conducted to identify all relevant publications on the psychometric properties of the Postural Assessment Scale for StrokeXAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. Schoppen et al. Measures that should not be related are not. After a stroke, the ability to control balance in the sitting and standing positions is a fundamental skill of motor behavior for achieving autonomy in everyday activities. Functional mobility measure was the 6 Minute Walk Test (6MWT), with a minimal clinically important difference (MCID) of 233 ft for gait speed of >0.4 m/s . Performance-oriented assessment of mobility problems in elderly patients. Analysis of balance relies either on clinical scales or on instrumentation. Systematic error refers to bias that influences scores in a specific direction in a fairly consistent way, e.g., one neurologist in a group tends to rate all patients as being more disabled than do other neurologists in the group. Activity limitations are difficulties in performance of activities. A method of measuring reliability . More: It is generally understood to be the extent to which a measure is stable or consistent and produces similar results when administered repeatedly. Measuring Health: A Guide to Rating Scales and Questionnaires True variation is that variation which actually reflects differences in the construct under study, e.g., the actual severity of neurological impairment. Effect of force-feedback treatments in patients with chronic motor deficits after a stroke. 43. Evidence based practice tools for home Health rehabilitation Rockwood, K., Awalt, E., Carver, D., MacKnight, C. (2000). MDC is the minimal change required to ensure the change is not the result of measurement error. Measures of Adult General Performance Tests.
True variation is that variation which actually reflects differences in the construct under study, e.g., the actual severity of neurological impairment. This last finding greatly strengthens the content validity of the PASS. 2021 Sep 17;100(37):e27250. Some are included in global neurological or functional assessment.4567891011 More recently, clinical scales have been proposed that are specifically designed to assess posture in hemiplegic patients.11213141516 Most of these scales are constructed with ordinal items or are time related, providing helpful data for clinical practice or research.1456789101213141516. This work presents many theories of motor control, but focuses on a systems theory of motor control and a clinical or "task-oriented" approach to examination and intervention. speed measures, the TUG was the most able to detect change. Patients were included over an 18-month period only if they had suffere… velocity in both healthy participants and patients with strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow.
Intrarater reliability, ie, the consistency of results from 1 administration of the test to another, was assessed with the κ-coefficient and Pearson product moment correlation between 2 consecutive scorings from a unique rater. Stroke Rehabilitation: Guidelines for Exercise and Training to Optimize Motor Skill. Relationships among walking performance, postural stability, and functional assessments of the hemiplegic patient. Mao et al. Objective: The Postural Assessment Scale for Stroke Patients (PASS) is used to assess static and dynamic balance of stroke patients. There are a wide variety of methods for measuring correlation including: intraclass correlation coefficients (ICC), the Pearson product-moment correlation coefficient, and the Spearman rank-order correlation. was observed between scores obtained by the same rater on two consecutive visits (r = 0.93). Postural tasks vary from test to test. These results are comparable with those of Partridge and Edwards (91%/63%)11 and Feigin et al (80% of patients sitting without support by the third week).1, Content validity, ie, the extent to which the sampling of items reflects the aim of the index, had already been widely documented in studies referring to the Fugl-Meyer scale (see Sanford et al20 for a review).

The “Timed Up & Go” is dependent on chair type. The TUG is a general physical performance test used to assess mobility, balance and locomotor performance in elderly people with balance disturbances.
Predicting the probability for falls in community-dwelling older adults using the Timed Up & Go Test. Table 3 summarizes the results of Pearson correlation coefficients between PASS scores on D30 and other clinical scales. An excellent Spearman correlationThe extent to which two or more variables are associated with one another. Minimal training is required to score the test or interpret the results.
More. is negative because a high score on the Berg Balance Scale indicates normal balance, whereas a high score on the TUG indicates abnormal functioning. These results suggest that the TUG is a sensitive and specific measure for identifying elderly individuals who are prone to falls. Disablement following stroke. of the TUG in 12 patients with Parkinson’s disease and 12 subjects without Parkinson’s disease. 2008 May;88(5):559-66. doi: 10.2522/ptj.20070205. The inter-rater reliabilityA method of measuring reliability .
Because nearly 40% of patients score 36/36 on D90, we recommend using more difficult items after this date, eg, the step test.34. (1999) examined the intra-rater reliabilityThis is a type of reliability assessment in which the same assessment is completed by the same rater on two or more occasions. Morris et al. Group- and Individual-Level Responsiveness of the 3-Point Berg Balance Scale and 3-Point Postural Assessment Scale for Stroke Patients. This information helped (will help) to: Testing for disease in people without symptoms.
Whether you are a student or a clinician, if you work with patients with neuromuscular and musculoskeletal impairments, you will find this text supplies a strong foundation in and appreciation for the field of orthotics and prosthetics that ... Figure 4. of the TUG in elderly patients. Fifty-eight patients were prospectively included in our neurological rehabilitation unit within the first month after a first unilateral hemispheric acute stroke. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. This text provides the most up-to-date information on evidence-based practice, the concepts underlying evidence-based practice, and implementing evidence into the rehabilitation practice. Customer Service If the phenomenon being measured fluctuates substantially over time, then the test-retest paradigm may significantly underestimate reliability. Known groups:
This method of evaluating reliability is appropriate only if the phenomenon that the scale measures is known to be stable over the interval between assessments.
The “Get Up and Go” test (the original TUG) was developed by Mathias, Nayak, and Issacs in 1986. It has ultimately become a very helpful clinical tool for monitoring patients’ weekly progress, which is a type of validation by use.
As defined by the International Classification of Functioning, Disability and Health, activity is the performance of a task or action by an individual. The Postural Assessment Scale for Stroke Patients (PASS) was developed specifically for assessing balance in stroke patients.
Steffen, T. M., Hacker, T. A., Mollinger, L. (2002).
This practical guide summarizes and evaluates current knowledge in the field of cerebellar disorders. It has shown high intrarater and interrater reliability (9), good individual item agreement (11), and acceptable or high test-retest reliability (7, 12). The results of this study suggest that the TUG has high inter-rater reliabilityA method of measuring reliability . Norén, A. M., Bogren, U., Bolin, J., Stenstrom, C. (2001). All data are analysed anonymously. Ng and Hui-Chan (2005) found that the TUG was able to distinguish healthy elderly individuals from patients with strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. For some attributes, no gold standard exists. Splitting them into 2 different groups is thus not necessary for the early postural assessment of stroke survivors. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. Choose the best procedure for each patient with the help of detailed coverage describing each technique's effects and desired outcomes. Review clinical trials that document the effectiveness of manual techniques. This indicates that it is possible to predict functional prognosis from the PASS on D30. The fact that such items are not suitable for an objective standardized assessment is supported by the studies of Maloin et al31 and Poole and Whitney.32 These studies emphasized the lack of validity of the Fugl-Meyer sitting balance items owing to the 2 protective reaction items, which greatly differ from other postural tasks.31 Moreover, it should also be stated that the objective assessment of protective reaction was revealed to be unreliable in our 5-year experience2 ; the item “leaning forward and touching the feet” seemed more relevant in the standing than in the sitting position. • Stroke ¡ MDC (acute): 6-7 points2 ¡ MDC (chronic): 4.66 points (superscript 2) to 6.7 points10 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. Metric properties include validity, reliability, internal consistency, lack of ceiling or floor effects inside the target population, and ability to discriminate different populations.29. The postural performance of patients soon after a stroke has been found to be closely correlated with long-term functional improvement.123 Because it may help in establishing the severity and prognosis of a stroke, the early assessment of balance in stroke survivors is an important part of the clinical examination.

If the phenomenon being measured fluctuates substantially over time, then the test-retest paradigm may significantly underestimate reliability. Beginning with detailed information on risk factors, epidemiology, prevention, and neurophysiology, the book details the acute and long-term treatment of all stroke-related impairments and complications. (2000) examined the convergent and discriminant validityMeasures that should not be related are not. Please enable it to take advantage of the complete set of features! Lying and sitting items are easier. There are a wide variety of methods for measuring correlation including: intraclass correlation coefficients (ICC), the Pearson product-moment correlation coefficient, and the Spearman rank-order correlation. Administering the PASS requires no special equipment except a chronometer.
Balance in elderly patients: The “Get-Up and Go” test. The mean PASS score was then 35.7 (range 32 to 36). (56%) were calculated for TUG scores of > 11.1 seconds. These are also referred to as function. Standing without support (feet position free, no other constraints), 1=can stand without support for 10 seconds or leans heavily on 1 leg, 2=can stand without support for 1 minute or stands slightly asymmetrically, 3=can stand without support for more than 1 minute and at the same time perform arm movements above the shoulder level, 4. This new paradigm brings promising perspectives but raises questions regarding the therapy assisted by computers. To address these issues, this book intends to clarify the multidisciplinary aspects of medical engineering. More. Mobile Measures is an outcome measure calculator and reference tool for physical and occupational therapists. Moderate negative correlations observed with the Postural Assessment Scale for Stroke Patients (PASS) suggest that clinicians should consider administration of the BLS in conjunction with other balance or postural control outcome measures that have well-established psychometric properties and are validated in the stroke population. Supine to sitting up on the edge of the table, 9. The TUG can be used with, but is not limited to, persons with strokeXAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow.
Semmes Weinstein Monofilaments 43.
observed with intermediate scores in the “Get Up and Go”.
Some studies used a timed task for the standing position, either in static12 or dynamic14 conditions. Reliability properties were assessed in a separate sample of 12 patients.
Timed up and go cut off for older adults? Rivermead Assessment of Somatosensory Performance 40. See also “ceiling effect.” with the TUG. A correlation can be positive (as one variable increases, the other also increases – for example height and weight typically represent a positive correlation) or negative (as one variable increases, the other decreases – for example as the cost of gasoline goes higher, the number of miles driven decreases.
D. M., Suurmeijer, M. (1993). See also “Specificity.” and specificitySpecificity refers to the probability that a diagnostic technique will indicate a negative test result when the condition is absent (true negative). These different ratings are then compared, generally by means of correlation. The Postural Assessment Scale for Stroke patients (PASS) was elaborated in concordance with 3 main ideas: (1) basically, postural control relies on 2 domains, which must both be assessed: the ability to maintain a given posture and to ensure equilibrium in changes of position; (2) a useful scale should be applicable for all patients, even those with very poor postural performance; and (3) a sensible scale should contain items with increasing levels of difficulty. Epub 2017 Sep 9.
This method of evaluating reliability is appropriate only if the phenomenon that the scale measures is known to be stable over the interval between assessments. performance measures examined twice, 7 days apart, ranging from r = -0.84 to r = -0.92 (these correlations are negative because a high score on the TUG indicates abnormal functioning, whereas a high score on other gaitThe pattern of walking, which is often characterized by elements of progression, efficiency, stability and safety. Note: You can check more than one reason. The TUG is not appropriate for clients with severe cognitive impairments that prevent understanding of the tasks. PASS has demonstrated good measurement properties for reliability and validity, but its predictive effect for ambulation in stroke patients has not been investigated. This method of evaluating reliability is appropriate only if the phenomenon that the scale measures is known to be stable over the interval between assessments. The OARS IADL also had excellent correlations with the TUG for all participants and with participants with cognitive impairment alone (r = -0.70 and r = -0.70, respectively). is not the preferred method of assessing inter-rater reliabilityA method of measuring reliability . TUG has been found to predict nursing home placement and risk of falling. Out of seven studies examining the test-retest reliabilityA way of estimating the reliability of a scale in which individuals are administered the same scale on two different occasions and then the two scores are assessed for consistency. Intra-rater: Although the TUG has been developed as a screeningTesting for disease in people without symptoms. of the TUG in patients with peripheral arthritis. Results—Normative data obtained in 30 age-matched healthy subjects are presented.

Postural Assessment Scale for Stroke Patients
Stroke‐Adapted Sickness Impact Scale‐ 30 44.
In using test-retest reliability, the investigator needs to take into account the possibility of practice effects, which can artificially inflate the estimate of reliability (National Multiple Sclerosis Society). (2006) examined the construct validityReflects the ability of an instrument to measure an abstract concept, or construct. Correlations Between D30 PASS Scores and Other Clinical Measures, Table 4. Chen YM, Huang YJ, Huang CY, Lin GH, Liaw LJ, Lee SC, Hsieh CL. Throughout the book the chapters provide detailed practical information on state-of-the-art clinical applications of these devices following stroke, spinal cord injury, and other neurologic disorders. No gold standardA measurement that is widely accepted as being the best available to measure a construct. Among the clinical measurements available for assessing postural abilities, only a few are specifically dedicated to hemiplegic patients (Table 1).
OBJECTIVE: The Postural Assessment Scale for Stroke Patients (PASS) is used to assess static and dynamic balance of stroke patients. PASS has demonstrated good measurement properties for reliability and validity, but its predictive effect for ambulation in stroke patients has not been investigated. Stroke‐Adapted Sickness Impact Scale‐ 30 Note: Caution should be taken in interpreting these findings as the Spearman correlationThe extent to which two or more variables are associated with one another.
The total variation in any given score may be thought of as consisting of true variation (the variation of interest) and error variation (which includes random error as well as systematic error).
This correlation is called the “effect size correlation”. N2 - Objective: The Postural Assessment Scale for Stroke Patients (PASS) is used to assess static and dynamic balance of stroke patients. The PASS on D30 was strongly correlated with the total FIM score (r=0.75; P<10−6), the transfer FIM items (r=0.74; P<10−6), and the locomotion FIM items (r=0.71; P<10−6) on D90. of Daily Living Scale (OARS IADL), OARS ActivitiesAs defined by the International Classification of Functioning, Disability and Health, activity is the performance of a task or action by an individual. Postural assessment is a key point of the rehabilitation program in stroke patients. Frequency distribution and density trace of PASS scores on D30. There are a wide variety of methods for measuring correlation including: intraclass correlation coefficients (ICC), the Pearson product-moment correlation coefficient, and the Spearman rank-order correlation. It is generally understood to be the extent to which a measure is stable or consistent and produces similar results when administered repeatedly.
Equilibrium was measured with the PASS on day 30 (D30) and day 90 (D90) after stroke onset.
In using test-retest reliability, the investigator needs to take into account the possibility of practice effects, which can artificially inflate the estimate of reliability (National Multiple Sclerosis Society). 7272 Greenville Ave. The kinematics of the support orientation and stabilization were analyzed by means of an accelerometer fixed under the platform and used as an inclinometer.
