A number of recent papers have suggested that the series of time intervals produced in continuation tapping may have fractal properties. This proposition, nevertheless, was only based on the visual appraisal of graphical results, and was not statistically supported. In the present study, we applied the ARMA/ARFIMA modeling procedures proposed by Wagenmakers, Farrell, and Ratcliff (2005) to test...

We study the tapping dynamics of a one dimensional Ising model with symmetric kinetic constraints. We define and test a variant of the Edwards hypothesis that one may build a thermodynamics for the steady state by using a flat measure over the metastable states with several macroscopic quantities fixed. Various types of tapping are compared and the accuracy of this measure becomes quickly excel...

Qualitative and quantitative performance on the Halstead Finger Tapping test may help differentiate brain dysfunctional patients from normal controls. "Normal" and "abnormal" finger tapping patterns during this task have been characterized and illustrated pictorially. Data from 65 patients with traumatic brain injury (TBI) and 15 normal controls support the dual proposition that (1) abnormal fi...

A 72-hour aquifer test was conducted to investigate the yield and interconnectivity of deep fracture systems in the City of Conyers, Rockdale County, Georgia. Wells tapping the deep fracture systems in the underlying igneous and metamorphic crystalline rock have yields ranging from 100 to 350 gallons per minute and can be pumped on a continuous basis. During the test, drawdown in excess of 30 f...

The Mixed Shih-Tzu dog, 3 years old and 4.3 kg body weight, had clinical signs of unable to stand, both rear limbs suffer from diplegic lameness so that they are only able rely on forelimbs. owner said her dog is traumatized by a four-wheeled vehicle. results blood profile before surgery showed physiological, an increase in leukocyte cells 18.83 x103/µL. radiographic examination with ventral-do...

The memory impairment of a patient suffering from functional retrograde amnesia was assessed both during the amnesic episode and after its termination. The patient's performance on a task tapping semantic memory was nearly identical on the two test occasions, but his performance on a task tapping episodic memory substantially changed across test sessions. Cueing procedures revealed that in spit...

OBJECTIVES The rapid finger-tapping test (RFT) is an important method for clinical evaluation of movement disorders, including Parkinson's disease (PD). In clinical practice, the naked-eye evaluation of RFT results in a coarse judgment of symptom scores. We introduce a novel computer-vision (CV) method for quantification of tapping symptoms through motion analysis of index-fingers. The method i...

Despite promising advantages such as low cost and portability of functional near-infrared spectroscopy (fNIRS), it has yet to be widely implemented outside of basic research. Specifically, fNIRS has yet to be proven as a standalone tool within a clinical setting. The objective of this study was to assess hemodynamic concentration changes at the primary and premotor motor cortices as a result of...

Quantification of neuromotor symptoms with device-based measures provides a useful supplement to clinical evaluation. Research using the CATSYS has established its utility as a computerized measurement system to quantify neuromotor function. The primary objective of this study is to provide technical guidance on the use of the CATSYS in Parkinson's disease (PD). Forty-four patients with idiopat...
