Average Measure

Background: In clinical and research settings, ankle joint dorsiflexion needs to be reliably measured. Dorsiflexion is often measured by goniometry, but the intrarater and interrater reliability of this technique have been reported to be poor. Many devices to measure dorsiflexion have been developed for clinical and research use. An evaluation of 12 current tools showed that none met all of the desirable criteria. The purpose of this study was to design and develop a device that rates highly in all of the criteria and that can be proved to be highly reliable. Methods: While supine on a treatment table, 14 participants had a foot placed in the Charles device and ankle joint dorsiflexion measured and recorded three times with a digital inclinometer. The mean of the three readings was determined to be the ankle joint dorsiflexion. Results: The analysis used was intraclass correlation coefficient (ICC). There was very little difference in ICC single or average measures between left and right feet, so data were pooled (N = 28). The single-measure ICC was 0.998 (95% confidence interval, 0.996-0.998). The average-measure ICC was 0.998 (95% confidence interval, 0.995-0.999). Limits of agreement for the average measure were also very good: −1.30° to 1.65°. Conclusions: The Charles device meets all of the desirable criteria and has many innovative features, increasing its appropriateness for clinical and research applications. It has a suitable design for measuring dorsiflexion and high intrarater and interrater reliability.

Ankle Joint Dorsiflexion

The Lidcombe template was introduced in 1991 for the nonweightbearing assessment of ankle joint dorsiflexion, and it has shown excellent reliability in impaired and unimpaired adult populations. We discuss limitations of the original template and test the reliability of a modified apparatus in an adolescent population. Intrarater and interrater reliability were assessed for 14 children (28 limbs) aged 7 to 14 years, returning intraclass correlation coefficient (1,1) results of greater than 0.99 for both aspects of reliability.

A Prospective Study

Background: Goniometric measurement is currently being used as a diagnostic and outcomes assessment tool for ankle joint dorsiflexion. Despite its common use, its interrater and intrarater reliability has been questioned. Methods: This is a prospective study examining whether the experience of the examiner or the technique used affects the interrater and intrarater reliability for measuring ankle joint dorsiflexion. Fourteen asymptomatic individuals (8 male and 6 female) with a mean age of 28.2 years (range, 23–52) were enrolled into this study. The years of clinical experience of the five examiners averaged 10.4 years (range, 0–26). Four examiners used a modified Root, Weed and Orien method of measuring ankle joint dorsiflexion. The fifth examiner utilized a nonstandardized technique. A standard goniometer was used for bilateral measurements of ankle joint dorsiflexion with the knee extended and flexed. All five examiners repeated each measurement three times during each of the three sessions, with each session spaced at least 1 week apart. Results: The interclass correlation coefficient reveals a moderate intrarater and poor interrater reliability in ankle joint dorsiflexion measurements using a standard goniometer. More importantly, further analysis indicates that the use of a standardized technique for measurement of ankle joint dorsiflexion or years of clinical experience does not increase the intrarater or interrater reliability. Conclusions: The utility of the goniometric measurement of ankle joint dorsiflexion may be limited. (J Am Podiatr Med Assoc 101(5): 407–414, 2011)

Advantages And Disadvantages

Background: Evaluation of range of motion (ROM) is integral to assessment of the musculoskeletal system, is required in health fitness and pathologic conditions, and is used as an objective outcome measure. Several methods are described to check ROM, each with advantages and disadvantages. Hence, this study introduces a new device using a smartphone goniometer to measure ankle joint ROM. Objective: To test the reliability of smartphone goniometry in the ankle joint by comparing it with the universal goniometer (UG) and to assess interrater and intrarater reliability for the smartphone goniometer record (SGR) application. Methods: Fifty-eight healthy volunteers (29 men and 29 women aged 18–30 years) underwent SGR and UG measurement of ankle joint dorsiflexion and plantarflexion. Two examiners measured ankle joint ROM. Descriptive statistics were calculated for descriptive and anthropometric variables, as were intraclass correlation coefficients (ICCs). Results: There were 58 usable data sets. For measuring ankle dorsiflexion ROM, both instruments showed excellent interrater reliability: UG (ICC = 0.87) and SGR (ICC = 0.89). Intrarater reliability was excellent in both instruments in ankle dorsiflexion: UG and SGR (mean ICC = 0.91). For measuring ankle plantarflexion, both instruments showed excellent interrater reliability: UG (ICC = 0.76) and SGR (ICC = 0.82). Intrarater reliability was excellent in both instruments in ankle plantarflexion: UG (mean ICC = 0.85) and SGR (mean ICC = 0.82). Conclusions: Smartphone-based goniometers can be used to assess active ROM of the ankle joint because they can achieve a high degree of intrarater and interrater reliability.

Context:The forward-step-down (FSD) test may be used to identify underlying pathologies related to lower-extremity injuries. However, research on its interrater reliability is limited.Objective:To assess the interrater reliability of the FSD test with a broad cohort of clinicians and to compare the level of agreement with an expert panel.Design:Single-measure, interrater reliability.Setting:Annual conference of the Israeli Physical Therapy Society.Participants:15 healthy subjects who performed the FSD test and 142 physical therapists (PTs) who evaluated performance.Methods:Each subject performed the FSD while being videoed. Six videos were selected by an expert panel for analysis. After viewing the videos, FSD performance was rated by 142 PTs, as well as by the expert panel, using a 3-level scale.Main Outcome Measures:Interrater reliability determined by intraclass correlation coefficient (ICC) and percentage of agreement with the expert panel.Results:Fair to good reliability and acceptable agreement were found for the entire sample of raters (ICC –.61, agreement 74%). The percentage of agreement was greater in the subgroup of raters who were familiar with the FSD than in those who were not (78.08% vs 69.32%, respectively, P = .004). Years of work experience did not affect the percentage of agreement (P = .141).Conclusions:Fair to good interrater reliably of the FSD test was demonstrated by a broad cohort of PTs. The findings support the clinical utility of the FSD test as an assessment tool for quality of movement.

Abstract Research groups are increasingly utilizing value frameworks, but little is known of their reliability. To assess framework concordance and interrater reliability between two major value frameworks currently in use, we identified all previously published datasets containing both scores from the American Society of Clinical Oncology Value Framework (ASCO-VF) and grades from the European Society for Medical Oncology-Magnitude of Clinical Benefit Scale (ESMO-MCBS). The intraclass correlation coefficient (ICC) was used to assess interrater reliability. Four eligible studies contained drugs evaluated by both value frameworks, resulting in a dataset of 39 grades/scores for discrete drug indications. ICC was 0.82 (95% confidence interval = 0.70 to 0.90) for ASCO-VF and 0.88 (95% confidence interval = 0.80 to 0.93) for ESMO-MCBS. Absolute concordance was found to be 5% for ASCO-VF and 44% for ESMO-MCBS, increasing to 74% and 80% when deviations within 20 points and 1 grade were considered, respectively. Interrater reliability of ASCO-VF and ESMO-MCBS is, therefore, near perfect, while absolute concordance is poor. This has implications when considering framework outputs in drug funding or treatment decision making.

Rivers are a leading location for drowning, yet little is known about people’s usage of these waterways. This pilot study aimed to test the use of direct observations to calculate river usage. Direct observations were conducted at regular intervals within defined zones at four river drowning locations in Australia (including weekends and the Australia Day national public holiday). Data recorded were date and time of observation; total people (including males, females, children, and adults); and number of people on, in, and beside the water. Univariate analysis with mean (SD) and range was conducted. Interrater reliability for observations was determined using the intraclass correlation coefficient (ICC) (one-way random-effects, average measures model), with a 95% confidence interval (CI). Across 149 time points, 309 observations resulted in 13,326 river interactions observed by multiple observers. There was an average of 39 people (M = 39.4, SD = 29.4, range = 0–137) per observation, 44 people (M = 44.2, SD = 32.7, range = 0–37) on an average weekend, and 97 people (M = 96.8, SD = 58.1, range = 20–190) on Australia Day. More females (M = 20.6, SD = 16.0, range = 0–83) than males (M = 18.3, SD = 14.5, range = 0–68) were observed. More people were observed in the water (M = 20.6, SD = 20.4, range = 0–84) than beside or on the water. Interrater reliability was excellent, consistently above 0.900 for all variables collected (apart from the variable of beside the river). Despite males accounting for 80% of river drowning fatalities, more females were observed than males. Increased visitation on the Australia Day public holiday may be linked to increased drowning risk. This study detailed a simple approach to data collection, exploring exposure within a defined zone at river locations. River usage is dynamic, with people’s movement in and out of the water changing their risk exposure. Observational-based data collection for drowning, particularly for rivers, is an important yet highly neglected area of research.

Ankle dorsiflexion measurement is important for clinical and research use. With so much evidence on the unreliability of goniometric measurements, a systematic review was performed to investigate various alternative techniques for measuring ankle dorsiflexion in the nonneurologic patient. All of the major databases were queried electronically to identify studies that used any method of ankle dorsiflexion measurement in the nonneurologic subject. Keywords included ankle dorsiflexion NOT cerebral palsy NOT stroke, the latter to exclude neurologic conditions. In 755 studies that used some form of ankle joint dorsiflexion measurement, ten different techniques were identified that included various apparatuses designed specifically for this purpose. Reliability testing of these techniques involved test-retest trials with small student populations as subjects, which returned high intraclass correlation coefficient scores. However, their methodological quality would have benefitted from the use of an actual patient population and comparison with a reference standard. When validating ankle dorsiflexion measurement techniques, actual patient populations should be used, otherwise papers would score poorly on methodological quality assessment. Standardizing patient position, foot posture, amount of moment applied, and reference landmarks will ensure that various trial results can be compared directly.

Objective. This study aimed to describe the interrater and intrarater reliability of the flexicurve index, flexicurve angle, and manual inclinometer in swimmers. A secondary objective was to determine the level of agreement between the inclinometer angle and the flexicurve angle and to provide an equation to approximate one angle from the other.Methods. Thirty swimmers participated. Thoracic kyphosis was measured using the flexicurve and the manual inclinometer. Intraclass correlation coefficient, 95% confidence interval, and standard error of measurement were computed.Results. The flexicurve angle and index showed excellent intrarater (ICC = 0.94) and good interrater (ICC = 0.86) reliability. The inclinometer demonstrated excellent intrarater (ICC = 0.92) and interrater (ICC = 0.90) reliability. The flexicurve angle was systematically smaller and correlated poorly with the inclinometer angle (R2=0.384). The following equations can be used for approximate conversions: flexicurve angle = (0.275 × inclinometer angle) + 8.478; inclinometer angle = (1.396 × flexicurve angle) + 8.694.Conclusion. The inclinometer and flexicurve are both reliable instruments for thoracic kyphosis measurement in swimmers. Although the flexicurve and inclinometer angles are not directly comparable, the approximate conversion factors provided will permit translation of flexicurve angle to inclinometer angle and vice versa.

This study examines whether observers reliably categorize selected speech production behaviors in hearing-impaired children. A group of experienced speech-language pathologists was trained to score the elicited imitations of 5 profoundly and 5 severely hearing-impaired subjects using the Phonetic Level Evaluation (Ling, 1976). Interrater reliability was calculated using intraclass correlation coefficients. Overall, the magnitude of the coefficients was found to be considerably below what would be accepted in published behavioral research. Failure to obtain acceptably high levels of reliability suggests that the Phonetic Level Evaluation may not yet be an accurate and objective speech assessment measure for hearing-impaired children.

Communication and communication behaviors in situational contexts are essential conditions for well-being and quality of life in people with dementia. Measuring methods, however, are limited. The CODEM instrument, a standardized observational communication behavior assessment tool, was developed and evaluated on the basis of the current state of research in dementia care and social-communicative behavior. Initially, interrater reliability was examined by means of videoratings (N = 10 people with dementia). Thereupon, six caregivers in six German nursing homes observed 69 residents suffering from dementia and used CODEM to rate their communication behavior. The interrater reliability of CODEM was excellent (mean κ = .79; intraclass correlation = .91). Statistical analysis indicated that CODEM had excellent internal consistency (Cronbach’s α = .95). CODEM also showed excellent convergent validity (Pearson’s R = .88) as well as discriminant validity (Pearson’s R = .63). Confirmatory factor analysis verified the two-factor solution of verbal/content aspects and nonverbal/relationship aspects. With regard to the severity of the disease, the content and relational aspects of communication exhibited different trends. CODEM proved to be a reliable, valid, and sensitive assessment tool for examining communication behavior in the field of dementia. CODEM also provides researchers a feasible examination tool for measuring effects of psychosocial intervention studies that strive to improve communication behavior and well-being in dementia.
