Infants with Delayed Motor Performance

Pediatric Clinics of North America, 1982
In judging an infant’s motor competency, one must consider achievement of motor milestones, quality of motor performance, status of infantile reflexes, tone and strength, and family history. When an infant is found to have abnormal or delayed motor performance, it is essential to use a systematic approach to evaluation that delineates whether the ...

Limb apraxia and motor performance

Brain and Language, 1980
Abstract This study was desinged to determine if motor deficits in limb apraxia are task specific. Non-brain-damaged patients and apraxic and nonapraxic patients with left hemisphere damage performed language and limb apraxia tests and six motor tasks with the left hand. Contrary to previous data, no significant group differences occurred on a finger

Modeling Effects on Motor Performance

Research Quarterly. American Alliance for Health, Physical Education and Recreation, 1976
Abstract Four experiments examined the influence of observing a correct model (CM), a learning sequence model (LSM), and an incorrect model (IM) on the performance of two motor skills. The results of experiment 1 showed that the CM and LSM conditions facilitated performance on the first 10 trails, but not thereafter when compared to the IM group and a ...

Effects of Pain on Motor Performance

Journal of Sport and Exercise Psychology, 1990
The effects of experimentally induced pressure pain on the performance of a weight lifting task, a simple golf putting task, and a complex golf putting task were examined in male college students. It was found that pain did not affect performance of the weight lifting task, slightly hampered performance of the simple putting task, and severely hampered

Transient performance of induction motors

Electrical Engineering, 1944
IT has been the usual practice to solve induction-motor transient problems either on the basis of the familiar steadystate equivalent circuit or by calculations which require simplifying assumptions. These methods neglect important factors determining the performance.

Fine Motor Performance in Schizophrenia

Neuropsychobiology, 2008
Peripheral and central aspects of motor dysfunction were assessed in 12 schizophrenic and 12 normal subjects, using a test of control of finger movement based on the widely used smooth pursuit eye movement task. This was performed in order to investigate the basis of neuromotor dysfunction in schizophrenia.

A study of motor performance and motor learning in episodic ataxia

NeuroReport, 1997
Episodic ataxias are rare disorders in which periodic episodes of ataxia are separated by normal or near normal motor behaviour. They probably arise from dysfunctional membrane ion channels in the cerebellum. A patient with episodic ataxia EA-2 performed three motor tasks, before, during and after an ataxic episode.

Motor Performance and Concurrent Cognitive Tasks

Journal of Motor Behavior, 1981
Twenty students tapped between two targets while concurrently performing either a verbal or a visuospatial cognitive task. Speed of tapping and consistency revealed right- and left-hand disruption during solving either the con-current verbal or visuospatial task respectively.

Starting Performance of Synchronous Motors

Transactions of the American Institute of Electrical Engineers, 1927
This paper deals with the theory underlying the starting performance of the salient-pole synchronous motor equipped with damper windings. The theory, while involving some approximations, is accurate enough for practical engineering calculations. Formulas are developed for the starting torque, pull-in torque and inrush.
