Questions related to Motor Development
I am planning a study on the effect of special interventions on the motor development of children from two upper and lower socioeconomic Status . I would need some references that determine the role of SES in effectiveness of intervention for children.
I'd appreciate your suggestions.
How can we calculate the winding's turn number and slot number in brushless dc motor design with all electrical and magnetic considerations?
I would also appreciate some help with the PWM circuitry.
Young children nowadays are often restricted in their play as modern societal living often fails to encourage outdoor play / gross motor development / physical activity etc.
I need a study/piece of literacture which indicates this finding.
Any other related research would also be very welcomed!
Please and thank you.
With changing pedaling technique, or with forced supramax training, or mental training, or changing seat position, etc.?
I am looking for validated instruments that measure balance (side-by-side, semi-tandem and tandem stance), gait (3 meter walking), chair rise (5x) and "walking - turning 180° - walking back" in people with dementia.
Unfortunately, the Short Physical Performance Battery and the Timed Up and Go Test are not validated for dementia patients.
I would be very grateful if you could help me out!
Thanks in advance,
In our study we have a small sample and need to create subgroups of the GMFCS levels. Is there a generally excepted way to do this?
The test is developed for more or less typically developing infants age 3-18 months.
Hey there, I'm currently writing my graduation paper and I have a chapter where I have to compare the normal development with the development of a child with DCD.
We are working on build a scale to evaluate motor development at a first division soccer school in Brasil.
It's very hard to find articles about this relations. If you have informations (articles, journals, books) please forward to me. Thank you!
Articles after 2012 are interesting to me! Thank you!
Today I saw the circuit box of my Single phase borewell motor. It had 3 capacitors one was written as start capacitor and two of 50Mfd capacitors. I know we need a start capacitor and a run capacitor for motor working but here the two capacitors of 50Mfd were connected during the motor running and one capacitor had a parallel resistor to it while the other didn't have any resistor with it.my question is why do we need 3 capacitor while we can use only two capacitors?
I am specifically looking to see if the literature says they enhance the development of fine motor skills, specifically pincer grasp for writing or not. I am finding it hard to get anything from searches as I'm not sure what key terms to use.
Do stator poles and rotor poles on the generator must be equal?
I have a project on nine phase self excited induction generator and have to use a 3 phase 1.5 KW AC motor which must be re winded to a 9 phase must use integer winding.winding. I'm having a tough time with calculations.

In my practical application requirement i want higher torque and at lower speed motor is it possible to design a normal PERMANENT MAGNET DC MOTOR to a high torque dc motor with change some modifications in winding and permanent magnets ?
In the last years I have studied how CNS and Spinal Cord interact for generating a reaching movement.
I'm writing on the current opinions about how CNS controls reaching movements. Because there are a lot of different positions about this topic i want to be sure that no one is omitted in my thesis.
So, in your opinion, which are the parameters encoded by the motor cortex in a motor command? Or, in other words, how CNS controls reaching movements?
Seeing the inductance profiles one can judge the ripple and its minimization. Are there any other approaches?
How I can identify the working of PMSM according to the angle obtained from rotor position sensor? For example, suppose the angle is 30 degrees, how can I know which phases are conducted?
I am looking into a 3D-experiment on spatial awareness. The software we want to use can either be projected using a 3D-TV (active shutter, at least 1920x1080, 65") or a 3D-projector (DLP link, refresh rate min 120z).
However, the question is, what is the better solution for high qualitative presentation of the stimuli. Does anyone have experience with the different setups? Are there any studies comparing both projection modes?
Thanks for the help
We have a small BLDC motor(160W) and the load of the motor is constant. I want to control the speed of the rotor.
We don't have access to the rotor, so we should use sensorless method, but we have problem in detecting the rotor position.
The motor is 4 poles and 3 phase BLDC.
Can anybody help us?

Hi there, I have been using the BOT-2 to test Motor Skill of Children. Unfortunately, some careless undergraduate student's have "misplaced" the red laminated target which is part of the kit. I cant seem to find the option to buy a replacement target Pearson Clinical. Id appreciate it if anyone could give me the measurements for the target as I cant seem to find them listed in the manual either.
I have a brushed DC motor, with unknown parameters (R,L, J, ...)
How I can determine the parameters of such motor by using the output shaft speed vs input voltage?
I am thinking of using the Peabody Developmental Motor Scales-2 to assess motor development in very preterm infants <34w. What is your opinion of these scales for this purpose? Any pitfalls or problems I should be aware of?
Is it important to start the gold-sprint race? What is the correct knee angle at start (left, and right)? What is the correct position of the pedals? When you are pedalling with high rpm, what is the correct range of knee angles? What is the differential knee angle range in which the sprinter can achieve the best or optimal highest rpm? How to define it? What do you set to reach these angles (seat position or pedal touching point)? How to improve the mentioned parameters with setting the body position (more forward or backward –why)? Is it important to change the main working bundle of muscles load or to charge both all the way (quadriceps or iliopsoas)?
Requirements for the test: (a) it should yield age equivalent scores, (b) it should cover the (developmental) age range of 3 years to about 16 years.
I am familiar with the Movement ABC 2, but unfortunately this test does not provide age equivalents.
I'm a Motor Behavior's Ph.D. student. My interest is how performance in fundamental skills changes with age (children, adolescents and adults). l am having troubles finding articles in this area. I need some recommendations of authors or studies in this area.
While the inverted-U hypothesis claim the individual should experience a moderate level of arousal to achieve a high level of performance, the drive theorists argue that the higher levels of arousal results in better performance. Reversal theorists assume that individuals interpret arousal differently depending on their present state and that the interpretation affects their performance. Catastrophe theorists predict that a sudden and abrupt drop in performance occurs as arousal get beyond the optimal level; and theorists of the zones of optimal functioning argue that for best performances to occur, athletes may need individualized optimal levels of arousal and other emotions. tThe present model predicts that, for best and peak performances to occur, athletes need only to create an arousal level similar to the one they have experienced throughout training sessions. For peak performance, athletes do not need to have high or low arousal levels. It is important that they create the same level of arousal throughout training sessions and competition. In other words, high levels of arousal can be beneficial if athletes experience such heightened levels of arousal during some consecutive training sessions. Similarly, low levels of arousal can be beneficial if athletes experience such low levels of arousal during some consecutive training sessions.
With all my heart, I would like to invite the specialists in the field of sport psychology and motor behavior to provide me with their professional comments because I am trying to enhance the model. Besides, I announce my full readiness to share the knowledge of the field with the specialists and investigators (specifically, MA and PhD students in the field of psychology, sport psychology and motor behavior).

We have dynamic gait stability for locomotion in gait that is quantified in some ways such as dynamical system theory and inverse pendulum. I am asking to know how we can quantify "equilibrium,balance,postural stability without locomotion"(without moving).
And then how about the above terms in some difficult balance motions like the ones are done in ballet dancing?
