  • inhibitory control of adjacent Finger movements while performing a modified version of the halstead Finger Tapping Test effects of age education and sex
    Journal of The International Neuropsychological Society, 2020
    Co-Authors: George P Prigatano, Carlos Wellington Goncalves, Sandro Barbosa De Oliveira, Sheila Marques Denucci, Roberta Monteiro Pereira, Lucia Willadino Braga
    Abstract:

    OBJECTIVE Selective motor inhibition is known to decline with age. The purpose of this study was to determine the frequency of failures at inhibitory control of adjacent Finger movements while performing a repetitive Finger Tapping task in young, middle-aged and older adults. Potential education and sex effects were also evaluated. METHODS Kinematic recordings of adjacent Finger movements were obtained on 107 healthy adults (ages 20-80) while they performed a modified version of the Halstead Finger Tapping Test (HTFF). Study participants were instructed to inhibit all Finger movements while Tapping with the index Finger. RESULTS Inability to inhibit adjacent Finger movements while performing the task was infrequent in young adults (2.9% of individuals between 20 and 39 years of age) but increased with age (23.3% between the ages of 40 and 59; 31.0% between ages 60 and 80). Females and males did not differ in their inability to inhibit adjacent Finger movements, but individuals with a college education showed a lower frequency of failure to inhibit adjacent Finger movements (10.3%) compared to those with a high school education (28.6%). These findings were statistically significant only for the dominant hand. CONCLUSION Selective motor inhibition failures are most common in the dominant hand and occur primarily in older healthy adults while performing the modified version of the HFTT. Monitoring selective motor inhibition failures may have diagnostic significance.

  • neuroimaging correlates of the halstead Finger Tapping Test several years post traumatic brain injury
    Brain Injury, 2004
    Co-Authors: George P Prigatano, Sterling C Johnson, Shawn D Gale
    Abstract:

    Eight healthy volunteers and seven post-acute patients with a history of severe traumatic brain injury (TBI) performed the Halstead Finger Tapping Test while undergoing functional magnetic resonance imaging (fMRI). Patients with TBI were on average 18.5 years post-trauma and at that time had normal or near normal Tapping speeds. The fMRI analysis revealed greater bilateral frontal activation in healthy controls while Tapping only in the right hand compared to patients with TBI. The maximum area of activation differences involved the supplementary motor area. Voxel-based morphometry (VBM) failed to reveal signs of atrophy to explain these findings. Different patterns of brain activation in patients with TBI compared to healthy controls may be seen even when the level of behavioural performance of patients is generally within normal limits.

  • pyramidal tract and alternate motor fibers complementarily mediate motor compensation in patients after hemispherotomy
    Scientific Reports, 2020
    Co-Authors: Jennifer Gaubatz, Leon Ernst, Conrad C Prillwitz, Bastian David, Guido Luchters, Johannes Schramm, Bernd Weber, Rainer Surges, Elke Hattingen, Gottfried Schlaug
    Abstract:

    Motor function after hemispheric lesions has been associated with the structural integrity of either the pyramidal tract (PT) or alternate motor fibers (aMF). In this study, we aimed to differentially characterize the roles of PT and aMF in motor compensation by relating diffusion-tensor-imaging-derived parameters of white matter microstructure to measures of proximal and distal motor function in patients after hemispherotomy. Twenty-five patients (13 women; mean age: 21.1 years) after hemispherotomy (at mean age: 12.4 years) underwent Diffusion Tensor Imaging and evaluation of motor function using the Fugl-Meyer Assessment and the index Finger Tapping Test. Regression analyses revealed that fractional anisotropy of the PT explained (p = 0.050) distal motor function including Finger Tapping rate (p = 0.027), whereas fractional anisotropy of aMF originating in the contralesional cortex and crossing to the ipsilesional hemisphere in the pons explained proximal motor function (p = 0.001). Age at surgery was found to be the only clinical variable to explain motor function (p < 0.001). Our results are indicative of complementary roles of the PT and of aMF in motor compensation of hemispherotomy mediating distal and proximal motor compensation of the upper limb, respectively.

  • a statistical characterization of the Finger Tapping Test modeling estimation and applications
    Biomedical and Health Informatics, 2015
    Co-Authors: Daniel Austin, Holly Jimison, James Mcnames, Krystal A Klein, Misha Pavel
    Abstract:

    Sensory-motor performance is indicative of both cognitive and physical function. The Halstead–Reitan Finger Tapping Test is a measure of sensory-motor speed commonly used to assess function as part of a neuropsychological evaluation. Despite the widespread use of this Test, the underlying motor and cognitive processes driving Tapping behavior during the Test are not well characterized or understood. This lack of understanding may make clinical inferences from Test results about health or disease state less accurate because important aspects of the task such as variability or fatigue are unmeasured. To overcome these limitations, we enhanced the tapper with a sensor that enables us to more fully characterize all the aspects of Tapping. This modification enabled us to decompose the Tapping performance into six component phases and represent each phase with a set of parameters having clear functional interpretation. This results in a set of 29 total parameters for each trial, including change in Tapping over time, and trial-to-trial and tap-to-tap variability. These parameters can be used to more precisely link different aspects of cognition or motor function to Tapping behavior. We demonstrate the benefits of this new instrument with a simple hypothesis-driven trial comparing single and dual-task Tapping.

  • Measuring motor speed through typing: a surrogate for the Finger Tapping Test
    Behavior Research Methods, 2011
    Co-Authors: Daniel Austin, Holly Jimison, Tamara Hayes, Nora Mattek, Jeffrey Kaye, Misha Pavel
    Abstract:

    Motor speed is an important indicator and predictor of both cognitive and physical function. One common assessment of motor speed is the Finger-Tapping Test (FTT), which is typically administered as part of a neurological or neuropsychological assessment. However, the FTT suffers from several limitations, including infrequent in-person administration, the need for a trained assessor and dedicated equipment, and potential short-term sensory–motor fatigue. In this article, we propose an alternative method of measuring motor speed, with face validity to the FTT, that addresses these limitations by measuring the interkeystroke intervals (IKI) of familiar and repeated login data collected in the home during a subject’s regular computer use. We show significant correlations between the mean Tapping speeds from the FTT and the median IKIs of the nondominant ( r = .77) and dominant ( r = .70) hands, respectively, in an elderly cohort of subjects living independently. Finally, we discuss how the proposed method for measuring motor speed fits well into the framework of unobtrusive and continuous in-home assessment.
