In the present work we studied the mobility of young pianists ́ wrists to predict their potential vulnerability to suffer from Repetitive Strain Injury (RSI). First, we observed that 222 individuals out of the 341 pianists studied (65.1% of the total) presented or had presented RSI. Second, from among affected performers we chose those that were younger than 16 years old (67 individuals) to anal...

[Purpose] Training using an arm weight-bearing device combined with upper-limb reaching apparatus to facilitate motor paralysis recovery, named the "Reaching Robot", as well as Repetitive Facilitation Exercise were applied to a patient with severe impairment of the shoulder and elbow due to incomplete spinal cord injury and the effects were examined. [Subjects and Methods] A 66-year-old man wit...

BACKGROUND The potential to accurately perform cervical movements during more challenging tasks might be of importance to prevent dysfunctional motion characteristics. Although sensorimotor function during dual-task conditions are of increasing interest in biomedical and rehabilitation research, effects of such conditions on movement consistency of the neck have not yet been investigated. OBJ...

Normal subjects were used to evaluate a fiber optic instrumented glove for semi-automated goniometric measurement. The glove electronically records and transmits hand and finger position to a host computer by measuring the amount of joint flexion. The glove was put through a series of range-of-motion (ROM) tests with five subjects. Metacarpal (MP) and proximal interphalangeal (PIP) joint angles...

Akinetopsia is a rare syndrome in which a patient specifically loses the ability to perceive visual motion following bilateral cortical lesions outside the striate cortex. We describe a patient who showed akinetopsia recurrently as epileptic seizures. The patient was a 61-year-old man. At age 46, a cerebral arteriovenous malformation in the right parietal lobe was discovered. At age 58, he bega...

Application of oral fast release amantadine and levodopa may induce an improvement of motor symptoms in patients with Parkinson's disease (PD). The objective of this trial was to investigate the clinical efficacy of a fast release amantadine sulfate formulation on simple and complex movement performance and putative relations to the pharmacokinetic behavior in PD patients. We challenged two coh...

To evaluate the clinical significance of reverse redistribution (RR) of resting 201Tl single photon emission computed tomography (SPECT) in patients with vasospastic angina (VSA), we performed left ventriculography, coronary angiography and resting 201Tl-SPECT in 22 patients with VSA. Left ventriculography showed abnormal wall motion in 17 of 22 patients (77%) and 37 of 154 segments. Thirty-one...

Certain repetitive arrangements of luminance gradients elicit the perception of strong illusory motion. Among them, the " Rotating Snakes Illusion " has generated a large amount of interest in the visual neurosciences, as well as in the public. Prior evidence indicates that the Rotating Snakes illusion depends critically on eye movements, yet the specific eye movement types involved and their a...

This paper proposes a scan-matching simultaneous localisation and mapping (SLAM)-based Iterative Closest Point algorithm using laser scan information and images in an indoor environment. The ICP algorithm, which is one of the scan-matching methods calculates the closest position iteratively by adjusting the motion vector and rotation matrix of the model. The matching process requires a great de...
