Clinical evaluation of the refined clothespin relocation test
Prosthetics & Orthotics International, 2019
Background: The refined clothespin relocation test is a test used to evaluate the performance of a prosthesis user by analysing the compensatory motions and time to complete a grasping and placement exercise. The test has been studied previously with a motion capture laboratory and has now been adapted for a clinical setting. A comparison of prosthesis user to an able-bodied group is needed to determine efficacy as an assessment tool. Objective: To modify the previous refined clothespin relocation test and assess whether it can distinguish between able-bodied and prosthesis users. Study design: Comparative analysis. Methods: Forty-two able-bodied subjects and three prosthesis users completed the adapted refined clothespin relocation test protocol. Average refined clothespin relocation test scores describing the degree of compensatory movements and the time to complete the protocol were compared using a Mann–Whitney U-test. Results: A significant difference was found in the refined c...
Refined clothespin relocation test and assessment of motion
Prosthetics & Orthotics International, 2017
Background: Advancements in upper limb prosthesis design have focused on providing increased degrees of freedom for the end effector through multiple articulations of a prosthetic hand, wrist and elbow. Measuring improvement in patient function with these devices requires development of appropriate assessment tools. Objectives: This study presents a refined clothespin relocation test for measuring performance and assessing compensatory motion between able-bodied subjects and subjects with upper limb impairments. Study design: Comparative analysis. Methods: Trunk and head motions of 13 able-bodied subjects who performed the refined clothespin relocation test were compared to the motion of a transradial prosthesis user with a single degree of freedom hand. Results: There were observable differences between the prosthesis user and the able-bodied group. The assessment used provided a clear indication of the differences in motion through analysis of compensatory motion. Conclusion: The ...

Validation studies of the human movement analysis panel for hand/arm performance
Journal of Neuroscience Methods, 2007
The human movement analysis panel (HMAP) measures separable components of arm motion and simple and complex finger coordination. HMAP testing takes 30 minutes to administer. In separate experiments we have validated the HMAP against the standard grooved pegboard and measures of gait speed, and demonstrated important learning effects over both short durations of days, and longer intervals of months to years in normal subjects of different ages. Stepwise regression demonstrated the strongest correlation between the HMAP complex motor times and pegboard both-hand removal (R 2 = 0.52, p = 0.002 for dominant and R 2 = 0.33, p = 0.02 for non-dominant hands). The most consistent and sensitive measure of HMAP motor performance overall was the complex motor time. The HMAP is a short-duration, easily administered, objective quantitative test of motor function, with potential applications in aging, and in Parkinson's Disease and related motor disorders. The HMAP has a smaller version used in primates, so that measurements made in primate models of disease and its treatment are directly comparable to analogous clinical measurements made in the corresponding human disease.
A psychometric evaluation of the Arm Motor Ability Test
Journal of Rehabilitation Medicine, 2013
Objective: To further examine the psychometric properties of a 9-item version of the Arm Motor Ability Test (AMAT-9) in persons with stroke. Subjects: Thirty-two community-dwelling persons > 6 months post-stroke undergoing robotics treatment (mean age = 56.0 years, time post-stroke = 4.1 years, National Institutes of Health Stroke Scale score = 4.1, and AMAT-9 score = 1.22). Methods: Construct validity (including Rasch analyses) used baseline data prior to treatment (n = 32). Standardized response mean was calculated for subjects completing the protocol (n = 29). The Wolf Motor Function Test (WMFT), Fugl-Meyer Assessment (FMA), Action Research Arm Test (ARAT), and Stroke Impact Scale (SIS) were also administered. Results: Spearman-rank correlation coefficients between AMAT-9 and the WMFT, FMA, and ARAT were strong (0.78-0.79, all p < 0.001). The correlation between the AMAT-9 and SIS Hand Function sub-score was stronger than that between the AMAT-9 and the Communication subscore (0.40, p = 0.025 and-0.16, p = 0.39, respectively). Rasch analyses provided evidence for an appropriate hierarchical structure of item difficulties, unidimensionality, and good reliability. The AMAT demonstrated a comparable standardized response mean of 0.98. Conclusions: The AMAT-9 is valid and responsive among subjects scoring in the lower range of the scale. It has the advantage of assessing function and by eliminating the standing item from the previous iteration, it may be more easily used with severely impaired patients.
Reference values and psychometric properties of the Lower Extremity Motor Coordination Test
Archives of Physical Medicine and Rehabilitation, 2014
Objectives: (1) To create predictive nomograms for the dominant and nondominant limbs on the Lower Extremity Motor Coordination Test (LEMOCOT) using reference values, and (2) to determine the inter-and intrarater reliability for the LEMOCOT; the best scoring method (first vs mean of the first 2 vs mean of the last 2 vs mean of 3 vs the highest of 3 trials); the best testing method (direct vs video observation); and the ability to detect real change (smallest real difference [SRD] and standard error of the measurement [SEM]). Design: Normative and methodological study. Setting: Metropolitan area. Participants: Healthy individuals (NZ320, 50% women) in 7 age groups: 20 to 29, 30 to 39, 40 to 49, 50 to 59, 60 to 69, 70 to 79, and !80 years. Each group had 50 participants, except for !80 years (nZ20). Interventions: Not applicable. Main Outcome Measure: LEMOCOT. Results: Age and sex explained 48% of the variance in the LEMOCOT scores for the dominant limb and 44% for the nondominant limb (125<F<148; P<.001). No significant differences were found regarding the different scoring methods (.12<F<1.02; .10<P<.92), and all of them demonstrated good reliability (intraclass correlation coefficients between .90 and .99; P<.001). There was agreement between scores from direct and video observation (limits of agreement À1.99 to 1.85; À1.55 to 1.62). Appropriate SEM (2.27e1.85) and SRD (6.27e5.11) values were found. Conclusions: Reference values were determined for the LEMOCOT, and predictive nomograms were created based on age and sex. The LEMOCOT is reliable, needing only 1 trial (after familiarization) to generate reliable scores; can be scored from either direct or video observation; and has the ability to detect real change over time.
Intra- and inter-rater reliability of a modified measure of hand behind back range of motion
Manual Therapy, 2014
The aim of this reliability study was to identify the clinimetric properties, specifically intra-and interrater reliability, for measuring the functionally and clinically important hand behind back (combined shoulder internal rotation/adduction and elbow flexion) range of motion using a modified technique. Sixty asymptomatic participants (20 male, 40 female) aged 45.4 AE 11.7 years (mean AE SD). Hand behind back was measured as the distance from the mid-line between the posterior superior iliac spines (PSIS) to the tip of the thumb and recorded in centimetres above the PSIS (a positive measure) or below the PSIS (a negative measure). The intra-and inter-rater reliability for the measurement were excellent, with ICC (2,1) of 0.95 for intra-rater and ICC (2,2) of 0.96 for inter-rater reliability. The standard error of the measurement (SEM) and smallest real difference (SRD) values showed acceptable levels of measurement error, SEM 4.3 mm and SRD 12.8 mm for intra-rater reliability and SEM 2.6 mm and SRD 7.7 mm for interrater reliability. The assessment of hand-behind-back motion from a point equidistant between the PSISs to the tip of the thumb is more reliable than traditional methods and a useful clinical tool.
Clinical Biomechanics, 2014
Background: Quantitative measures of human movement quality are important for discriminating healthy and pathological conditions and for expressing the outcomes and clinically important changes in subjects' functional state. However the most frequently used instruments for the upper extremity functional assessment are clinical scales, that previously have been standardized and validated, but have a high subjective component depending on the observer who scores the test. But they are not enough to assess motor strategies used during movements, and their use in combination with other more objective measures is necessary. The objective of the present review is to provide an overview on objective metrics found in literature with the aim of quantifying the upper extremity performance during functional tasks, regardless of the equipment or system used for registering kinematic data. Methods: A search in Medline, Google Scholar and IEEE Xplore databases was performed following a combination of a series of keywords. The full scientific papers that fulfilled the inclusion criteria were included in the review. Findings: A set of kinematic metrics was found in literature in relation to joint displacements, analysis of hand trajectories and velocity profiles. These metrics were classified into different categories according to the movement characteristic that was being measured. Interpretation: These kinematic metrics provide the starting point for a proposed objective metrics for the functional assessment of the upper extremity in people with movement disorders as a consequence of neurological injuries. Potential areas of future and further research are presented in the Discussion section.
The Functional Dexterity Test: Test–retest reliability analysis and up-to date reference norms
Journal of Hand Therapy, 2013
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 testeretest 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: Testeretest 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.
