This paper presents the event approach to motor skill acquisition as a theoretical treatment of the learning and relearning of motor skill. 1) The use of norm-referenced developmental assesment tools and standardized qualitative assessment tool is an important component of infant movement evaluation. 2) The kinesthetic modality relaying movement and position imformation to the central nervous system is important for the detection and corretion of movement error. 3) The event approach treats the actor and the environment as inseparable in the acquisition of skills. 4) Motoy learning focuses almost entirely on how the skill is learned, contRolled and reTained. 5) Developmental assessment have needed an assessment of motor development. 6) A significant difference was found between articulation disorders children and motor coordination problem. 7) verbal ability is not essential for the learning of motor skills. 8) The Control of motor skills is a cognitive ability.

The purpose of this study was to test that motor skill training enhance motor function and cerebellar development. Using an animal model of fetal alcohol syndrome-which equates peak blood alcohol concentrations across developmental period-critifical periods for the effect of alcohol on body and cerebellar weigh was examined. The effect of motor skill training on motor function and cerebellar development of rat exposed alcohol on postnatal days 4 through 10 were studied. Newborn rats were assigned to one of two groups: (1) Control group (CG), via artificial rearing to milk formula and (2) experimental groups (EG), via 4.5g/kg/day of ethanol in a milk solution. After completion of the treatments, the pups were fostered back to lactating dams, and wearing they were raised in standard caged until they were postnatal 48 days. Rats from experimental group of postnatal treatment then spent 10 days in one of two groups: Experimental group II (EGII) was had got motor skill training (training traverse a set of 6 elevated obstacles) for 4 weeks. Experimental group I (EGI) was not trained. Before sacrificing, the rat got examined two behavioral test, body weigh and cerebellar weigh, then coronal sections were processed. The section was investigated the Purkije cell in the cerebellum using light microscope. The results of this study were as follows. 1. In body weight test, the outcome of alcohol groups were significantly lower than the normal group. 2. In cerebellar weight test, the outcome of EGI were significantly lower than CG and EGII. 3. In motor behavioral test, the outcome of EGI was significantly lower than NG and EGII. 4. In Purkinje cells counting test, the outcome of EGI was significantly lower than the NG and EGII. These result suggest that improved motor function induced by motor skill training after postnatal exposure is associated with dynamically altered expression of Purkinje cells and that is related with cerebellar function. Also, these data can potentially serve as a model for therapeutic intervention.

Purpose: The cerebellum is a region of brain structure that plays an important role in calibrating two different information of neural signal from descending motor commands and from ascending sensory inputs. Damage of the cerebellum shows a variety of classic motor symptoms such as postural and locomotor dysfunctions. Therefore, we tried to investigate motor function and skill in stroke patients with cerebellar lesions in sub-acute stage, and compare with these functions of patients with non-cerebellar lesions. Methods: Total twelve stroke patients with cerebellar lesion and 130 stroke patients with non-cerebellar lesions were retrospectively recruited in this study. For evaluation of motor strength, Motricity index (MI) for upper and lower limbs was tested. For measurement of motor skill function, the modified Brunnstrom classification (MBC), Manual function test (MFT), functional ambulatory category (FAC), and Barthel index were adopted. Results: In comparison of motor strength and motor skill function between two groups, statistical differences between the two groups were significantly observed only in upper MI and FAC. Although no significant differences were found in other variables, stroke patients with cerebellar lesion had higher scores in lower and total MI, MBC, and MFT, whereas they had lower scores in FAC and Barthel index. Conclusion: Our results showed that stroke patients with cerebellar lesion had greater impact on movement functions related to hand motor and walking ability in activities of daily life, compared with patients with non-cerebellar lesion, in spite of similar degree of motor function and skill between the two different lesioned-groups.

This study is intended to examine the motor skill learning and treadmill exercise on motor performance and synaptic plasticity in the cerebellar injured rats by harmaline. Experiment groups were divided into four groups and assigned 15 rats to each group. Group I was a normal control group(induced by saline); Group II was a experimental control group(cerebellar injured by harmaline); Group III was a group of motor skill learning after cerebellar injured by harmaline; Group IV was a group of treadmill exercise after cerebellar injured by harmaline. In motor performance test, the outcome of group II was significantly lower than the group III, IV(especially group III)(p<.001). In histological finding, the experimental groups were destroy of dendrities and nucleus of cerebellar neurons. Group III, IV were decreased in degeneration of cerebellar neurons(especially group III). In immunohistochemistric response of synaptophysin in cerebellar cortex, experimental groups were decreased than group I. Group III's expression of synaptophysin was more increased than group II, IV. In electron microscopy finding, the experimental groups were degenerated of Purkinje cell. These result suggest that improved motor performance by motor skill learning after harmaline induced is associated with dynamically altered expression of synaptophysin in cerebellar cortex and that is related with synaptic plasticity.

Purpose: This study examined whether there is a difference in motor learning through short-term repetitive movement practice in stroke survivors with a unilateral brain injury compared to normal elderly participants. Methods: Twenty-six subjects who were divided into a stroke group (n=13) or sex-aged matched normal elder group (n=13) participated in this study. To evaluate the effects of motor learning, the participants conducted a tracking task for visuomotor coordination. The accuracy index was calculated for each trial. Both groups received repetitive tracking task training of metacarpophalangeal joint for 50 trials. The stroke group performed a tracking task in the upper extremity insi-lesional to the damaged hemisphere, and the normal elder group performed the upper extremity matched for the same side. Results: Two-way repetitive ANOVA revealed a significant difference in the interactions ($time{\times}group$) and time effects. These results indicated that the motor skill improved in both the stroke and normal elder group with a tracking task. On the other hand, the stroke group showed lesser motor learning skill than the normal elder group, in comparison with the amount of motor learning improvement. Conclusion: These results provide novel evidence that stroke survivors with unilateral brain damage might have difficulty in performing ipsilateral movement as well as in motor learning with the ipsilateral upper limb, compared to normal elderly participants.

This article reviews the concepts of motor ability and motor skill and the models, theories, and treatment approaches of motor contorl. Reflex, hierarchical, and systems models of motor control are discussed. And muscle reeducation, neurodevelopment, motor relearning program, and contemporary task-oriented approach is also discussed. We consider that the concept of motor control is being changed and the treatment approach also is being changed. There are a number of reasons, the first is traditional trteatment approach has limitation. Second is theories of motor control is contineously developed. Third is new approach is coming to us. therefore, the therapists shoulder strive for acquisition of motor skill and motor ability. This article hope the successful integration of models and treatment approaches and its application in physical therapy practice.

Theoretical framework of motor learning is used to enhance perceptual motor skill in physical therapy intervention, which can be subdivided into two main types-explicit and implicit. The purpose of this study was to examine whether stroke patients with unilateral brain damage learn implicitly a motor skill using the arm ipsilateral to the damaged hemisphere. Speculation then followed as to the formation of therapeutic plans and instructions provided to patients with stroke. 20 patients with stroke and 20 normal participants were recruited. All the subjects practiced serial reaction time tasks for 30 minutes a day and retention tests on the following day. The tasks and tests involved pressing the corresponding buttons to 4 colored circles presented on a computer screen as quickly and accurately as possible. Patients with stroke responded more slowly than controls. However, both groups showed decreased reaction time in the experimental and retention periods. Also, there was no significant difference between both groups regarding explicit knowledge of consecutive order. Therefore, patients with stoke had the ability to learn implicitly a perceptual motor skill. Prescriptive instruction using implicit and explicit feedback may be beneficial for motor skill learning in physical therapy intervention for patients with brain damage.
