motor units (mus) reflect the function of the central nervous motor system. thus, the estimated mu number is a good option to investigate the functional movement disorder in the parkinson’s disease (pd). the purpose of this study was to compare the estimated mus number in the medial gastrocnemius (mg) muscle of the normal rats and those with the parkinsonism. the mg muscle of two age-matched gr...

objective the purpose of this study was to determine the prevalence and the most common risk factors of motor developmental delay in infants. materials & methods following ethical approval, a study was carried out on the prevalence and risk factors of infants with motor developmental delay. the first stage was conducted through a cross-sectional study to determine the prevalence of motor develo...

objectives: down syndrome (ds) is the most common multiple congenital anomaly syndrome associated with a developmental disability. children with down syndrome have delay in both motor and mental age. this study carried out to explore relationship between mental and motor age of children with ds. methods: a cross-sectional study was conducted on 60 participants with ds (5 to 7 years old) using r...

background and objectives: motor development is considered as a part of the process of growth and development in which the child, firstly gains control over his own body function, and then utilizes it for interaction and manipulation with the environment. the aim of this study was to standardize of peabody developmental motor scale (pdms) in normal children aged 72 to 83 months living in tehran...

abstract objective development is a complex process, completed over a specific period of time, through the maturation of the nervous system. it is affected by genetic, ethnic, nutritional, social, and economic factors; one of the environmental factors affecting the acquisition of motor skills in infants is the use of baby walkers. since this device is very commonly used for infants in our count...

background and objective: evaluation of degenerative changes of motoneurons and their related synapses can be useful in understanding the mechanisms of neurodegenerative diseases and their potential treatment. the present electron microscopic and immunohistochemical study investigates the axotomy-induced changes of adult spinal motoneurons up to 3 months following sciatic nerve transection. mat...

Optimization of specific power of axial flux permanent magnet brushless DC (PMBLDC) motor based on genetic algorithm optimization technique for an electric vehicle application is presented. Double rotor sandwiched stator topology of axial flux permanent magnet brushless DC motor is selected considering its best suitability in electric vehicle applications. Rating of electric motor is determined...

fundamental motor skills are the bases of special motor skills. in addition tomaturation, environmental promotion can influence these skills. the aim of thisstudy was to investigate and compare the effect of developmental gymnasticinstructional program and spark motor program as motor experiences onfundamental motor skills development in children aged between 6 and 8. for thispurpose, 120 child...

Induction motors are the most commonly used in the traction industries and electric vehicles, due to their low primary cost, low maintenance costs, and good performance. Speed identification is needed for the induction motor drives. However, using of speed sensors in the induction motor drives is associated with problems such as, extra cost, reduced reliability, added mounting space, etc.. Ther...

post-traumatic stress disorder (ptsd) is a chronic and progressive disorder that occurs after some traumas and accident. injuries and harm to health caused by motor vehicle accidents (mvas) have become an issue of global concern, as mvas are expected to be the third largest contributor to the worldwide burden of disease by the year 2020. chronic ptsd is a common consequence of mva and that it m...
