Neuromechanical Cost Functionals Governing Motor Control for Early Screening of Motor Disorders

Neuromechanical Cost Functionals Governing Motor Control for Early Screening of Motor Disorders

Developing a quantifier of the neural control of motion is extremely useful in characterizing motor disorders and personalizing the model equations using data. We approach this problem using a top-down optimal control methodology, with an aim that the quantity estimated from the collected data is representative of the underlying neural controller. For this purpose, we assume that during the fle...

A Low Cost Sensorless Control Drive Circuit for of Low Voltage Switched Reluctance Motor

Shaft position sensing is an essential part of switched reluctance (SR) motor drive In order to synchronize the pulses of phase current with the period of rising inductance of the proper motor phase. Direct sensors such as, Hall effect and optical encoder are commonly used in SR motors. The purpose of this paper is to present an indirect shaft positioning sensing known as "sensorless " control ...

Cerebral Palsy: Motor Types, Gross Motor Function and Associated Disorders

Objectives: Cerebral palsy (CP) describes a group of disorders in the development of movement and posture in the developing brain. The main aim of this study was to determine the distribution of motor impairment and associated disorders in a population of children with CP. Methods: This study was carried out in 2011 during three months, on 200 CP children. Multiple sources of ascertainment w...

Determine motor status of children with motor skills disorders using two scales of Bleck and Capute

Introduction: The motor prognosis of children with motor skills disorders is a major issue for their parents and the health professionals involved in their management. Prediction of prognosis in infancy is very difficult. Available and simple tests which can examine prognosis are Bleck infant’s reflexes and motor quotient of Capute. Objective: The aim of this study was to investigate the...
