validity and reliability of the functional Dexterity Test in children
Journal of Hand Therapy, 2017Co-Authors: Camden M Tissue, Paul F Velleman, Caroline W Steginkjansen, Dorit Haenosh Aaron, Barbara G Winthrop, Gloria R. GogolaAbstract:Abstract Study Design Clinical measurement study. Introduction The Functional Dexterity Test (FDT) has not been validated in children. Purpose of the Study To determine reliability and validity of the FDT in a pediatric population. Methods Intraclass Correlation Coefficients (ICCs) were used to calculate interrater and Test-reTest reliability in typically developing children. Pearson correlation coefficients were used to compare FDT speed with the Jebsen-Taylor Hand Function Test (JHFT) and with 2 activities of daily living tasks to establish validity in children with congenital hand differences. Results The FDT demonstrated excellent interrater (ICC, 0.99) and Test-reTest (ICC, 0.90) reliability. Pearson correlation coefficients exceeded 0.67 for JHFT subsets of fine Dexterity and were all less than 0.66 for JHFT subsets of gross grasp. Correlations with the activities of daily living tasks were good to excellent. FDT speeds in TD children exceeded those of children with congenital hand differences ( P Discussion Children with congenital hand differences are often treated early in life, making it important to reliably assess hand function of these young children to distinguish developmental change from changes due to interventions. The FDT can reliably measure functional progress over time, help clinicians monitor the efficacy of treatment, and provide families realistic feedback on their child’s progress. Conclusion The FDT is a valid and reliable instrument for the measurement of fine motor Dexterity in children.

Innovative evaluation of Dexterity in pediatrics
Journal of Hand Therapy, 2015Co-Authors: Susan V. Duff, Gloria R. Gogola, Dorit H. Aaron, Francisco J. Valero-cuevasAbstract:Abstract Study design Review paper. Introduction Hand Dexterity is multifaceted and essential to the performance of daily tasks. Timed performance and precision demands are the most common features of quantitative Dexterity Testing. Measurement concepts such as rate of completion, in-hand manipulation and dynamic force control of instabilities are being integrated into assessment tools for the pediatric population. Purpose To review measurement concepts inherent in pediatric Dexterity Testing and introduce concepts that are infrequently measured or novel as exemplified with two assessment tools. Methods Measurement concepts included in common assessment tools are introduced first. We then describe seldom measured and novel concepts embedded in two instruments; the Functional Dexterity Test (FDT) and the Strength–Dexterity (SD) Test. Discussion The inclusion of novel yet informative tools and measurement concepts in our assessments could aid our understanding of atypical Dexterity, and potentially contribute to the design of targeted therapy programs.

hand Dexterity in children administration and normative values of the functional Dexterity Test
Journal of Hand Surgery (European Volume), 2013Co-Authors: Gloria R. Gogola, Paul F Velleman, Shuai Xu, Adrianne M Morse, Barbara Lacy, Dorit H. AaronAbstract:Purpose To document normative values from the Functional Dexterity Test (FTD) for typically developing children and to optimize Test administration and interpretation. Methods A total of 175 typically developing children aged 3 to 17 years participated in the study. Children completed the 16-peg FDT with both hands, and elapsed time was recorded in seconds. Data were analyzed as 16/time, interpreted as speed (pegs per second). A linear regression analysis predicted speed from age and hand dominance. Results Functional Dexterity Test speed increased linearly in typically developing children by 0.04 pegs/s for each year of age. This rate of increase was the same for dominant and nondominant hands. Dominant hands were faster than nondominant hands by 0.09 pegs/s at all ages. There was no sex difference. Conclusions This study provides age-specific normative values for functional Dexterity in typically developing children in 2 formats: as a growth chart of FDT speed versus age and as a regression model that calculates expected speed given a child's age and Tested hand dominance. Recommended pediatric modifications to the FDT are to use speed (pegs per second) instead of time (seconds) to report results, and to not assess penalties. The norms presented allow clinicians to compare both speed and rate of change over time of pediatric patients with typically developing children, which makes it possible to distinguish developmental change from intervention. Type of study/level of evidence Diagnostic III.

trends in Dexterity and normative values for the functional Dexterity Test fdt
Journal of Hand Therapy, 2011Co-Authors: Sylvia S Gray, Barbara Winthrop Rose, Dorit H. Aaron, Paul F Velleman, Gloria R. GogolaAbstract:Centre, London, ON, Canada Purpose: The purpose of this study was to search and appraise the current evidence related to the psychometric properties of the Patient-rated Wrist Evidence (PRWE). Background: The PRWE is a commonly used outcome measure for assessing pain and functions in patients with different wrist/hand injuries. Previous studies have provided strong evidence of the psychometric properties of the PRWE; however a systematic review can provide better estimate regarding the usefulness of the PRWE. Methods: Medline, CINAHL, and Embase databases were searched for retrieving the relevant studies. In addition, hand searching of the retrieved studies also identified relevant studies. Sixteen studies were included in the review. Two raters independently followed standardized guidelines for data extraction and appraisal of the included studies. Descriptive summary of the psychometric properties was prepared. Results: Quality checkdetermined that 8 studies had quality level of greater than 70%. Construct validity of the PRWEwas commonly assessed with other similar outcomes such as the Disabilities of the Arm, Shoulder, and Hand questionnaire with Spearman’s correlation coefficient in range of 0.62e0.82 (p , 0.001). TestreTest reliability was determined on using Intraclass Correlation Coefficient which ranged between 0.78e0.94. Responsiveness was shown with Standardized Response Mean ranging from 1.51e2.27. Conclusion: The PRWE has demonstrated adequate psychometric properties in patients with different wrist/hand conditions. It has been translated in Chinese (Hong Kong), German, Swedish, Dutch, Japanese, andHindi languages and the versions of PRWE in these languages have also demonstrated satisfactory psychometric properties. Though investigated in some previous studies, the estimates of the clinically important difference can be derived from future studies for precise clinical application.

development of the functional Dexterity Test fdt construction validity reliability and normative data
Journal of Hand Therapy, 2003Co-Authors: Dorit H. Aaron, Caroline Stegink W JansenAbstract:Abstract Dexterity Tests take time to administer; however, the information obtained is an important component of a comprehensive examination of the hand. This article introduces a Dexterity Test suitable for use as part of routine examination of the hand. The Functional Dexterity Test (FDT) was developed as a measure of Dexterity that takes a minimum amount of time to administer, yet provides information regarding the patient's ability to use the hand for daily tasks requiring a 3-jaw chuck prehension between the fingers and the thumb. The Test was developed over 20 years. Interrater and intrarater reliability ranges between good and excellent. Construct validity was confirmed in 2 clinical studies. Preliminary normative data were obtained in 6 samples of convenience. Along with statistical data, this article provides equipment standards and instructions. J HAND THER. 2003;16:12-21.

the lower extremity Dexterity Test as a measure of lower extremity dynamical capability
Journal of Biomechanics, 2013Co-Authors: Mark A Lyle, Francisco J Valerocuevas, Robert J Gregor, Christopher M PowersAbstract:The capability of the lower extremity to dynamically interact with the ground is important for skilled locomotor performance. However, there is currently no Test method designed to specifically quantify this sensorimotor ability, which we refer to as lower extremity Dexterity. We describe a new method to quantify lower extremity Dexterity, examine its reliability (n¼ 10), and evaluate the extent to which it is associated with lower extremity strength and anthropometry in healthy young adults (n¼ 38). The lower extremity Dexterity Test (LED-Test)—an adaptation of the Strength–Dexterity Test for the fingers– consists of using the isolated lower extremity to compress a slender spring prone to buckling at low forces. The goal of the LED-Test is to sustain the highest compression force possible. Applying higher forces makes the spring increasingly unstable, thus achieving higher compression forces represents better ability to dynamically control instability at low force levels. As such, the LED-Test provides a novel way to quantify the capability of the lower extremity to regulate dynamic and unstable footground interactions at submaximal forces. LED-Test performance ranged between 88.6 and 119.6 N, Test-reTest reliability was excellent (ICC (2,3) ¼ 0.94), and the minimal detectable difference was 5.5 N. Performance was not correlated with strength or height (r 2 r 0.053, p4 0.05), and only weakly with body mass (r 2 ¼ 0.116, p ¼0.04). We propose that the unique lower extremity capability quantified by the LED-Test could be informative of skilled locomotor performance and injury risk.

the strength Dexterity Test as a measure of dynamic pinch performance
Journal of Biomechanics, 2003Co-Authors: Francisco J Valerocuevas, Niels Smaby, Madhusudhan Venkadesan, Margaret G E Peterson, Timothy M WrightAbstract:Abstract We have developed a method to quantify the dynamic interaction between fingertip force magnitude (strength) and directional control (Dexterity) during pinch with a novel strength–Dexterity (S–D) Test based on the principle of buckling of compression springs. The Test consists of asking participants to use key and opposition pinch to attempt to fully compress springs, in random order, with a wide range of combinations of strength and Dexterity requirements. The minimum force required to fully compress the spring and the propensity of the spring to buckle define the strength and Dexterity requirements, respectively. The S–D score for each pinch style was the sum of the strength values of all springs successfully compressed fully. We Tested 3 participant groups: 18 unimpaired young adults (⩽40 yr), 10 unimpaired older adults (>40 yr), and 14 adults diagnosed with carpo-metacarpal osteoarthritis (CMC OA) (⩾36 yr). We investigated the repeatability of the S–D Test with 74 springs by Testing 14 young adults twice on different days. The per-spring repeatability across subjects was ⩾94%. A minimum performance score for young adults was found as they all could compress a subset of 39 springs. Using this subset of springs, we compared the ability of the S–D score vs. maximal pinch force values to distinguish unimpaired hands from those with CMC OA of the thumb. The score for this 39-spring S–D Test distinguished between CMC OA and asymptomatic older adults, whereas pinch meter readings did not ( p

We investigated the repeatability of the S–D Test with 74 springs by Testing 14 young adults twice on different days. The per-spring repeatability across subjects was X94%. A minimum performance score for young adults was found as they all could compress a subset of 39 springs. Using this subset of springs, we compared the ability of the S–D score vs. maximal pinch force values to distinguish unimpaired hands from those with CMC OA of the thumb. The score for this 39-spring S–D Test distinguished between CMC OA and asymptomatic older adults, whereas pinch meter readings did not (po0:05). We conclude that the S–D Test is repeatable and applicable to clinical research. We propose including the S–D Test in studies aiming to quantify impairment and compare treatment outcomes in orthopaedic and neurological afflictions that degrade dynamic manipulation. r 2002 Elsevier Science Ltd.

Tuttavia, i pazienti mostrano anche una compromissione delle funzioni sensorimotorie, ma la relazione tra STC e destrezza manuale non e mai stata indagata. Obiettivi: Analizzare la correlazione tra destrezza manuale e severita della STC. Ulteriore obiettivo e stato l’analisi dell’accuratezza diagnostica della batteria clinica comprendente i Test provocativi (Phalen, Tinel) e il Functional Dexterity Test (FDT). Metodi: Un campione di 80 soggetti con sospetta STC e stato suddiviso 4 gruppi sulla base dell’EMG (severa/estrema-GrA, moderata-GrB, leggera/minima-GrC, negativa-GrD) e valutato in cieco mediante Phalen, Tinel e FDT. La relazione tra il FDT e l’allocazione dei soggetti e stata indagata mediante rho di Spearman, mentre i gruppi sono stati comparati tra loro con un’ANOVA univariata ed analisi post hoc di Tukey.

Risultati: E stata riscontrata una moderata (r=0.48, p<0.001) correlazione tra FDT e i 4 gruppi. L’ANOVA ha restituito una differenza significativa tra GrA vs. tutti gli altri e tra GrB vs. GrD. La batteria ha mostrato una sensibilita, specificita, rapporto di verosimiglianza positivo (LR+) e rapporto di verosimiglianza negativo (LR-) rispettivamente di 70%, 94%, 11.98 e 0.31. Conclusioni: I risultati di questo studio avvalorano l’ipotesi che i pazienti affetti da STC abbiano anche una compromissione della destrezza. Il FDT e stato in grado di discriminare tra tre livelli di severita (negativa; da minima a moderata; severa/grave), mantenendo un buon livello di accuratezza diagnostica in aggiunta ai Test provocativi.

the functional Dexterity Test Test reTest reliability analysis and up to date reference norms
Journal of Hand Therapy, 2013Co-Authors: Francesco Sartorio, Elisabetta Bravini, Stefano Vercelli, Giorgio Ferriero, Giuseppe Plebani, Calogero Foti, Franco FranchignoniAbstract:STUDY DESIGN: Clinical measurement. INTRODUCTION: Among the available Tests for fine finger Dexterity, the Functional Dexterity Test (FDT) has been indicated as a valid instrument to measure outcome in different conditions. PURPOSE OF THE STUDY: To analyze Test-reTest reliability, to study the influence of gender, age and hand dominance on the FDT score, and to collect reference norms for adult and elderly age-groups. METHODS: Test-reTest reliability was calculated with the Intraclass Correlation Coefficient (ICC) and Standard Error of Measurement (SEM) in a subgroup of 324 healthy volunteers. An enlarged sample of 698 subjects, Tested at least once, was used to present stratified data for age group, sex, and hand dominance, and ANOVA was used to investigate statistically significant differences between groups. RESULTS: The FDT showed excellent reliability (ICC > 0.90; SEM: <2 s for net times; <3 s for total scores). Age, gender and hand dominance significantly influenced FDT scores (p < 0.05), but no interaction between variables was found. CONCLUSIONS: FDT is confirmed as reliable, and up-to-date reference norms over a broad range of ages of the Italian adult population have been provided. LEVEL OF EVIDENCE: NA.
