conclusions results of the current study showed that at preschool stage girls had higher performance compared to boys in fine motor skills and at preschool stage boys had significantly higher performance compared to girls in gross motor skills. hence, it seems to be necessary to train preschool authorities in teaching fine and gross motor skills, considering the gender. patients and methods the...

conclusions the results showed that the dexterity fingers of patients suffering from stroke at the final stages of bronestrum is much closer to the dexterity of healthy controls. background one of the main problems of chronic stroke patients is the inability to move the fingers separately despite the passing of an extended period of time since the onset of the disease. dexterity is a fine motor...

1. We used transcranial magnetic stimulation (TMS) to study the role of plastic changes of the human motor system in the acquisition of new fine motor skills. We mapped the cortical motor areas targeting the contralateral long finger flexor and extensor muscles in subjects learning a one-handed, five-finger exercise on the piano. In a second experiment, we studied the different effects of menta...

Background and Objective: Achievement of motor skills is an important part of childhood development. There are some scales that commonly used for preschool-aged children including Peabody Developmental Motor Scales, 2nd edition (PDMS-2). A cross sectional study designed to compare motor skills of high risk and normal infants of 3 to 6 months of age. Methods: In this case control study, ...

Hemiplegic cerebral palsied (CP) children account 30% of CP children1, characterized by affected arm and leg on one side of the body2. Hemiplegic children had difficulties in performing fine motor hand activities and had abnormal upper limb posturing during gait and in any activities required effort3. Combination of spasticity, weakness, and sensory and motor control deficits reduced functional...

The effect of afferent stimuli on the firing pattern of single motor units has been studied in the human first dorsal interosseous muscle of the hand. A reproducible series of changes in the probability of motor unit firing was seen. There was evidence for an excitatory spinal reflex involving median nerve muscle afferent fibres and ulnar nerve motor fibres. Cutaneous and muscle afferent pathwa...

Performer autonomy (or self-control) has consistently been shown to enhance motor learning, and it can also provide immediate benefits for motor performance. Autonomy is also a key variable in the OPTIMAL theory of motor learning (Wulf & Lewthwaite, 2016). It is assumed to contribute to enhanced expectancies and goal-action coupling, affecting performance effectiveness and efficiency. The purpo...
