Pengaruh Penerapan Oral Motor Untuk Anak Speech Delay Usia 2-4 Tahun

Speech is one aspect of child development that starts from birth. By talking, children can communicate to those around them about themselves, about their condition and about what they want to convey. A child is said to be late in speaking if at the age the ability to process vocals and communicate is not in accordance with the age of the development period or is below the average age of the child. The impact that will be very visible and clearly felt is when communicating with the environment and experiencing difficulties in adaptation and socialization. Oro motor is the movement of the mouth (oral). In newborns this ability is carried out reflexively, then through the learning process an automatic and skilled oromotor will be achieved. Oral motor training is the coordination and movement of hard tissue, soft tissue, vascular system, and control of the nerves in the face and mouth areas that form the function of oral motor. Coordination of these structures is essential for speech, chewing and swallowing with a wide variety of food textures. In general, this paper is to review the results of research that identifies oral motor stimulation increasing the function of orofacial muscles in speech delay children. Method; qualitative descriptive with SSR (Single Subject Research) technique. Literature Review: The oral motor stimulation program includes activities to improve tongue literacy, lip control and chewing power. Oral motor stimulation includes active exercises and passive exercises. Results: The oral motor stimulation program can improve the function of orofacial muscles in children such as pronouncing letters, swallowing food and breathing properly. Language and speech disorders are a type of communication disorder which is indicated by a disturbance in the symbolic process. Language and speech disorders can be caused by disorders of the nervous system or abnormalities in organs related to language and speech processes. Oral motor stimulation can improve the functional ability of the muscles in the mouth area. Good oral motor skills will support the child's speech process.

Good and correct gross motor stimulation can lead children to achieve optimal development. Unfortunately, many children whose gross motor skills have not developed optimally, this is because in learning teachers tend to use the lecture method so that children are less involved and do not practice directly to develop gross motor skills. Through the game of jumping rope, in addition to training cooperation and understanding, jumping rope will also demand the child's brain and body to maximize performance and movement. So that it will make good and perfect growth and development between intelligence and movement in the face of obstacles and problems. The method used in this research is the classroom action research method. The subjects involved in this study were 23 students of group A at RA Al-Istiqomah GSI, Griya Serdang Indah B, Margatani Village, Kramatwatu District, Serang Regency, Banten. The final result of the study showed that 96% of children developed very well in gross motor skills. Through the game of jumping rope, children's gross motor skills are well stimulated.

Resting-state functional connectivity predicts motor cortex stimulation-dependent pain relief in fibromyalgia syndrome patients

MRI-based resting-state functional connectivity (rsFC) has been shown to predict response to pharmacological and non-pharmacological treatments for chronic pain, but not yet for motor cortex transcranial magnetic stimulation (M1-rTMS). Twenty-seven fibromyalgia syndrome (FMS) patients participated in this double-blind, crossover, and sham-controlled study. Ten daily treatments of 10 Hz M1-rTMS were given over 2 weeks. Before treatment series, patients underwent resting-state fMRI and clinical pain evaluation. Significant pain reduction occurred following active, but not sham, M1-rTMS. The following rsFC patterns predicted reductions in clinical pain intensity after the active treatment: weaker rsFC of the default-mode network with the middle frontal gyrus (r = 0.76, p < 0.001), the executive control network with the rostro-medial prefrontal cortex (r = 0.80, p < 0.001), the thalamus with the middle frontal gyrus (r = 0.82, p < 0.001), and the pregenual anterior cingulate cortex with the inferior parietal lobule (r = 0.79, p < 0.001); and stronger rsFC of the anterior insula with the angular gyrus (r = − 0.81, p < 0.001). The above regions process the attentional and emotional aspects of pain intensity; serve as components of the resting-state networks; are modulated by rTMS; and are altered in FMS. Therefore, we suggest that in FMS, the weaker pre-existing interplay between pain-related brain regions and networks, the larger the pain relief resulting from M1-rTMS.

Early initiation of electrical stimulation paired with range of motion after a volumetric muscle loss injury does not benefit muscle function.

What is the central question of this study? First, how does physical rehabilitation influence recovery from traumatic muscle injury? Second, how does physical activity impact the rehabilitation response for skeletal muscle function and whole-body metabolism? What is the main finding and its importance? The most salient findings were that rehabilitation impaired muscle function and range of motion, while restricting activity mitigated some negative effects but also impacted whole-body metabolism. These data suggest that first, work must continue to explore treatment parameters, including modality, time, type, duration and intensity, to find the best rehabilitation approaches for volumetric muscle loss injuries; and second, restricting activity acutely might enhance rehabilitation response, but whole-body co-morbidities should continue to be considered. Volumetric muscle loss (VML) injury occurs when a substantial volume of muscle is lost by surgical removal or trauma, resulting in an irrecoverable deficit in muscle function. Recently, it was suggested that VML impacts whole-body and muscle-specific metabolism, which might contribute to the inability of the muscle to respond to treatments such as physical rehabilitation. The aim of this work was to understand the complex relationship between physical activity and the response to rehabilitation after VML in an animal model, evaluating the rehabilitation response by measurement of muscle function and whole-body metabolism. Adult male mice (n=24) underwent a multi-muscle, full-thickness VML injury to the gastrocnemius, soleus and plantaris muscles and were randomized into one of three groups: (1) untreated; (2) rehabilitation (i.e., combined electrical stimulation and range of motion, twice per week, beginning 72h post-injury, for ∼8weeks); or (3) rehabilitation and restriction of physical activity. There was a lack of positive adaption associated with electrical stimulation and range of motion intervention alone; however, maximal isometric torque of the posterior muscle group was greater in mice receiving treatment with activity restriction (P=0.008). Physical activity and whole-body metabolism were measured ∼6weeks post-injury; metabolic rate decreased (P=0.001) and respiratory exchange ratio increased (P=0.022) with activity restriction. Therefore, restricting physical activity might enhance an intervention delivered to the injured muscle group but impair whole-body metabolism. It is possible that restricting activity is important initially post-injury to protect the muscle from excess demand. A gradual increase in activity throughout the course of treatment might optimize muscle function and whole-body metabolism.

High-frequency oscillations-based precise temporal resolution of short latency afferent inhibition in the human brain

ObjectiveSensorimotor integration is a crucial process for adaptive behaviour and can be explored non-invasively with a conditioned transcranial magnetic stimulation (TMS) paradigm - i.e. short-latency afferent inhibition (SAI). To gain insight into the sensorimotor integration phenomenon, we used two different approaches to combine peripheral and cortical stimulation in the SAI paradigm, measuring not only the latency of low frequency somatosensory evoked potentials (SEPs) but also the peaks of high frequency oscillations (HFOs) underlying SEPs. MethodsThe interstimulus intervals (ISIs) between the electrical stimulation of the median nerve and the motor cortex magnetic stimulation were determined relative to the latency of the earliest SEPs cortical potential (N20) or the HFOs peaks. In particular, the first and last negative and positive peaks of HFOs were extracted through a custom-made MATLAB script. ResultsThirty-three healthy subjects participated in this study. We found out that muscle responses after TMS were suppressed when ISIs were comprised between –1 to +3 ms relative to the N20 peak and at all ISIs relative to HFOs peaks, except for the first negative peak. ConclusionsCoupling peripheral and cortical stimulation at early interstimulus intervals – before the SEPs N20 peak - may modulate muscle response. SignificanceOur findings confirm that afferent inhibition is produced both through a direct (thalamus-motor cortex) and indirect (thalamus-somatosensory-motor cortex) pathway.

Effect of compressive therapy on sensorimotor function of the more affected upper extremity in chronic stroke patients: A randomized clinical trial.

Background:Common upper extremity (UE) physical impairments after stroke include paresis, abnormal muscle tone, and somatosensory affection. This study evaluated the effect of passive somatosensory stimulation using compressive therapy on sensorimotor function of the more affected UE in chronic stroke patients.Methods:Forty chronic stroke patients were enrolled in this study. They were randomized into 2 groups: Gr1 and Gr2. Three patients dropped out leaving us with a total of 37 patients completing the study. Gr1 received UE motor program for the more affected UE along with sham electrical stimulation while Gr2 had the same UE motor program along with passive somatosensory stimulation. The session duration in both groups was 85 min. Gr1 and Gr2 received a total of 36 sessions for 6 successive weeks. UE function in Gr1 and Gr2 was examined, before and after treatment using Box and Block test (BBT) and Perdue Pegboard test (PPBT) as measures of motor of both the more affected and less affected UE while the Nottingham sensory assessment (NSA) scale was used as a measure of sensory function of the more affected UE.Results:There were significant improvements in motor and sensory function of the more affected UE compared to the less affected UE in both groups, measured by the BBT, PPBT, and NSA scales post-treatment (P < .05). However, the comparison between both groups regarding improvement revealed no significant change (P > .05).Conclusion:Upper extremity motor and passive somatosensory stimulation techniques are effective in improving sensorimotor function of the more affected UE, but none of them had the advantage over the other, in terms of improving motor and sensory function in chronic stroke patients.

Developmental eye motion plasticity after unilateral embryonic ear removal in Xenopus laevis

SummaryGaze stabilization relies on bilateral mirror-symmetric vestibular endorgans, central circuits, and extraocular motor effectors. Embryonic removal of one inner ear before the formation of these structures was used to evaluate the extent to which motor outputs in the presence of a singular inner ear can develop. Near-congenital one-eared tadpoles subjected to separate or combinatorial visuo-vestibular motion stimulation exhibited comparable eye movements, though smaller in gain to controls, whereas isolated visuo-motor responses were unaltered. Surprisingly, vestibulo-ocular reflexes were robust during off-direction motion toward the missing ear in most cases and often attenuated during on-direction motion. This bidirectional plasticity of signal encoding appears to occur at the expense of vestibular reflexes during motion in the normally preferential activation direction of the singular ear. Consequently, formation of central vestibulo-motor circuits in one-eared animals likely relies on multi-neuronal homeostatic strategies, including enhanced afferent fiber activity in the attempt to adjust bilateral sensorimotor transformations.

Wii

Currently, there are more and more dependent old people with cognitive disorders in nursing homes, who have difficulties, even disabilities, in daily life activities such as washing, dressing, eating or orienting themselves. This represents a significant workload for caregivers. Non-drug approaches have a very wide field of action, impacting the resident as well as his environment. For example, video game such as Wii™have many advantages (low cost, easy to use, various games) and positive cognitive, motor, social and psychological effects The objective of this qualitative study was through the establishment of a Wii™animation in a nursing home. First, caregivers observed old people with advanced cognitive disorders in order to see changes over their participation. In a second step, these same caregivers were invited to describe their feelings about the participants reception of the Wii™animation, after three months of using the console. Five residents were observed and presented a gradual improvement in the understanding of the instructions (console usage and game rules), with more motivation and participation. Six caregivers observed these workshops for three months and highlighted positive reactions and final adherence to its implementation, a motivational impact and general positive effects (cognitive and motor stimulation, psychoaffective effects and favored social interactions).

Effect of Sensory Motor Stimulation on Enhancing Oral Feeding Readiness of Preterm Neonates

Effect of Sensory Motor Stimulation on Enhancing Oral Feeding Readiness of Preterm Neonates

Impact of a nurse education programme on oral feeding in a neonatal unit.

Premature neonates often experience feeding difficulties during their hospital stay, and evidence-based interventions have been shown to improve feeding outcomes. This study investigated whether an infant-cue based nurse educational feeding bundle accelerates the achievement of independent oral feeding in neonates in a neonatal intensive care unit. A quality improvement study with a pre, during and post intervention test design. All premature neonates admitted to the unit were eligible. The feeding programme included a four-month nurse training module and nurse coaching. A hundred and twenty-five nurses or nurse assistants attended the programme and 706 neonates were included. The median time to independent oral feeding (IOF) was 40, 36 and 37 days, respectively, for pre, during and post intervention. The reduction in time to IOF observed during the post-intervention period compared with the baseline period was significant (HR=1.32, CI 95%: 1.01-1.74). No difference was noted in the length of hospital stay between the three study periods. An infant-cue based nurse educational feeding bundle can promote earlier achievement of IOF in preterm neonates. This quality improvement study demonstrates the impact that a nurse-driven intervention in neonatal care can have on improving practice. Feeding interventions involve the early introduction of oral feeding, non-nutritive sucking (NNS), and oral motor stimulation, and should be individualized for each neonate. These individualized feeding interventions applied by all nurses and assistant nurses, can facilitate the achievement of earlier independent oral feeding in preterm infants and should be included in neonatal critical care nurse education programs.

Selective Enhancement of Post-Sleep Visual Motion Perception by Repetitive Tactile Stimulation during Sleep.

Tactile sensations can bias visual perception in the awake state while visual sensitivity is known to be facilitated by sleep. It remains unknown, however, whether the tactile sensation during sleep can bias the visual improvement after sleep. Here, we performed nap experiments in human participants (n = 56, 18 males, 38 females) to demonstrate that repetitive tactile motion stimulation on the fingertip during slow wave sleep selectively enhanced subsequent visual motion detection. The visual improvement was associated with slow wave activity. The high activation at the high beta frequency was found in the occipital electrodes after the tactile motion stimulation during sleep, indicating a visual-tactile cross-modal interaction during sleep. Furthermore, a second experiment (n = 14, 14 females) to examine whether a hand- or head-centered coordination is dominant for the interpretation of tactile motion direction showed that the biasing effect on visual improvement occurs according to the hand-centered coordination. These results suggest that tactile information can be interpreted during sleep, and can induce the selective improvement of post-sleep visual motion detection.SIGNIFICANCE STATEMENT Tactile sensations can bias our visual perception as a form of cross-modal interaction. However, it was reported only in the awake state. Here we show that repetitive directional tactile motion stimulation on the fingertip during slow wave sleep selectively enhanced subsequent visual motion perception. Moreover, the visual improvement was positively associated with sleep slow wave activity. The tactile motion stimulation during slow wave activity increased the activation at the high beta frequency over the occipital electrodes. The visual improvement occurred in agreement with a hand-centered reference frame. These results suggest that our sleeping brain can interpret tactile information based on a hand-centered reference frame, which can cause the sleep-dependent improvement of visual motion detection.

Homeostatic plasticity of eye movement performance in Xenopus tadpoles following prolonged visual image motion stimulation

Visual image motion-driven ocular motor behaviors such as the optokinetic reflex (OKR) provide sensory feedback for optimizing gaze stability during head/body motion. The performance of this visuo-motor reflex is subject to plastic alterations depending on requirements imposed by specific eco-physiological or developmental circumstances. While visuo-motor plasticity can be experimentally induced by various combinations of motion-related stimuli, the extent to which such evoked behavioral alterations contribute to the behavioral demands of an environment remains often obscure. Here, we used isolated preparations of Xenopus laevis tadpoles to assess the extent and ontogenetic dependency of visuo-motor plasticity during prolonged visual image motion. While a reliable attenuation of large OKR amplitudes can be induced already in young larvae, a robust response magnitude-dependent bidirectional plasticity is present only at older developmental stages. The possibility of older larvae to faithfully enhance small OKR amplitudes coincides with the developmental maturation of inferior olivary–Purkinje cell signal integration. This conclusion was supported by the loss of behavioral plasticity following transection of the climbing fiber pathway and by the immunohistochemical demonstration of a considerable volumetric extension of the Purkinje cell dendritic area between the two tested stages. The bidirectional behavioral alterations with different developmental onsets might functionally serve to standardize the motor output, comparable to the known differential adaptability of vestibulo-ocular reflexes in these animals. This homeostatic plasticity potentially equilibrates the working range of ocular motor behaviors during altered visuo-vestibular conditions or prolonged head/body motion to fine-tune resultant eye movements.

Giving stimulation in early childhood is very important for optimizing children's development, including fine motor skills. It is important to optimize fine motor development stimulation because it will affect the child's readiness to maximize the movements of the wrist and fingers. This also affects the coordination of the child's eye and hand functions so that he can process the information he receives at the same time. This study aims to determine the improvement of the child's eye and hand coordination after applying the method of thickening the dotted line to children aged 4 to 5 years in community service research through service learning at TK Aisyiyah Bustanul Atfhal II Perumnas Makassar City with a total of 4 participants. children. In its application, it uses a dotted line patterned drawing paper instrument, an observation sheet, and an evaluation sheet for the implementation of the intervention. The data obtained were analyzed using descriptive statistics. The results of this research show that the application of thickening the dotted line is effective in improving children's hand and eye coordination in carrying out activities simultaneously. This study implies that the development of hand-eye coordination in stimulated children has different speeds.

Post‐fatigue ability to activate muscle is compromised across a wide range of torques during acute hypoxic exposure

The purpose of this study was to assess how severe acute hypoxia alters the neural mechanisms of muscle activation across a wide range of torque output in a fatigued muscle. Torque and electromyography responses to transcranial and motor nerve stimulation were collected from 10 participants (27 years ± 5 years, 1 female) following repeated performance of a sustained maximal voluntary contraction that reduced torque to 60% of the pre‐fatigue peak torque. Contractions were performed after 2 h of hypoxic exposure and during a sham intervention. For hypoxia, peripheral blood oxygen saturation was titrated to 80% over a 15‐min period and remained at 80% for 2 h. Maximal voluntary torque, electromyography root mean square, voluntary activation and corticospinal excitability (motor evoked potential area) and inhibition (silent period duration) were then assessed at 100%, 90%, 80%, 70%, 50% and 25% of the target force corresponding to the fatigued maximal voluntary contraction. No hypoxia‐related effects were identified for voluntary activation elicited during motor nerve stimulation. However, during measurements elicited at the level of the motor cortex, voluntary activation was reduced at each torque output considered (P = .002, η p 2 = .829). Hypoxia did not impact the correlative linear relationship between cortical voluntary activation and contraction intensity or the correlative curvilinear relationship between motor nerve voluntary activation and contraction intensity. No other hypoxia‐related effects were identified for other neuromuscular variables. Acute severe hypoxia significantly impairs the ability of the motor cortex to voluntarily activate fatigued muscle across a wide range of torque output.

The potent α2-adrenoceptor antagonist RS 79948 also inhibits dopamine D2 -receptors: Comparison with atipamezole and raclopride

Neurochemical, electrophysiological and behavioral evidence indicate that the potent α2-adrenoceptor antagonist RS 79948 is also a dopamine (DA) D2 receptor antagonist. Thus, results from ligand binding and adenylate cyclase activity indicate that RS 79948 binds to D2 receptors and antagonized D2 receptor-mediated inhibition of cAMP synthesis at nanomolar concentrations.Results from microdialysis indicated that RS 79948 shared with the selective α2-adrenergic antagonist atipamezole the ability to increase the co-release of DA and norepinephrine (NE) from noradrenergic terminals in the medial prefrontal cortex (mPFC), except that RS 79948-induced DA release persisted after noradrenergic denervation, unlike atipamezole effect, indicating that RS 79948 releases DA from dopaminergic terminals as well. Similarly to the D2 antagonist raclopride, but unlike atipamezole, RS 79948 increased extracellular DA and DOPAC in the caudate nucleus.Electrophysiological results indicate that RS 79948 shared with raclopride the ability to activate the firing of ventral tegmental area (VTA) DA neurons, while atipamezole was ineffective.Results from behavioral studies indicated that RS 79948 exerted effects mediated by independent, cooperative and contrasting inhibition of α2-and D2 receptors. Thus, RS 79948, but not atipamezole, prevented D2-autoreceptor mediated hypomotility produced by a small dose of quinpirole. RS 79948 potentiated, more effectively than atipamezole, quinpirole-induced motor stimulation. RS 79948 antagonized, less effectively than atipamezole, raclopride-induced catalepsy.Future studies should clarify if the dual α2-adrenoceptor- and D2-receptor antagonistic action might endow RS 79948 with potential therapeutic relevance in the treatment of schizophrenia, drug dependence, depression and Parkinson's disease.

Fine Motor Stimulation of Children Through Coloring Activities in Early Childhood

This study examines the stimulation of children's fine motor skills through image coloring activities in group B of Dharma Wanita Majauleng Kindergarten, Wajo Regency. This research uses a quantitative approach with the type of research, the one-group pretest-posttest design. The sample in this study was 11 children. The data collection technique uses Pretest–Posttest Design, and the results are analyzed using descriptive quantitative. The results of the image coloring activity on the improvement of children's delicate motor stimulation showed that the measurement data from the pretest, the fine motor ability of students in the learning completion value of the low category. The results of post-test scores show that the average value of students' fine motor skills is very high, with classical learning completion scores achieved by all children. This study shows that the activity of coloring children's drawings can train children's strength in holding writing stationery so that students are trained to develop their fine motor skills.

Dosing Transcranial Magnetic Stimulation of the Primary Motor and Dorsolateral Prefrontal Cortices With Multi-Scale Modeling.

Transcranial magnetic stimulation (TMS) can depolarize cortical neurons through the intact skin and skull. The characteristics of the induced electric field (E-field) have a major impact on specific outcomes of TMS. Using multi-scale computational modeling, we explored whether the stimulation parameters derived from the primary motor cortex (M1) induce comparable macroscopic E-field strengths and subcellular/cellular responses in the dorsolateral prefrontal cortex (DLPFC). To this aim, we calculated the TMS-induced E-field in 16 anatomically realistic head models and simulated the changes in membrane voltage and intracellular calcium levels of morphologically and biophysically realistic human pyramidal cells in the M1 and DLPFC. We found that the conventional intensity selection methods (i.e., motor threshold and fixed intensities) produce variable macroscopic E-fields. Consequently, it was challenging to produce comparable subcellular/cellular responses across cortical regions with distinct folding characteristics. Prospectively, personalized stimulation intensity selection could standardize the E-fields and the subcellular/cellular responses to repetitive TMS across cortical regions and individuals. The suggested computational approach points to the shortcomings of the conventional intensity selection methods used in clinical settings. We propose that multi-scale modeling has the potential to overcome some of these limitations and broaden our understanding of the neuronal mechanisms for TMS.

Effect of environmental enrichment on aggression and the expression of brain-derived neurotrophic factor transcript variants in group-housed male mice

Social and environmental factors influence behavior via modulation of brain physiological functions. Environmental enrichment (EE) is an animal housing technique that provides complex sensory, motor, and social stimulation, leading to modifications in the innate aggressiveness in group-housed laboratory mice. Brain-derived neurotrophic factor (BDNF) is encoded by multiple splice variants and plays a critical role in controlling aggressive behavior in a transcript variant-specific manner. BDNF mediates the beneficial effects of EE on a variety of pathophysiological conditions. These findings led to the hypothesis that EE reduces aggressive behavior by altering the expression of Bdnf mRNA in a transcript variant-specific manner. To test this hypothesis, 3–4-week-old male C57BL/6 mice were randomly group-housed (5 mice per cage) under standard or EE conditions for 6–8 weeks. Aggressive behavior was monitored and levels of Bdnf mRNA variants in aggression-related brain regions were measured. Mice housed in EE cages displayed a significantly lower frequency of aggressive interactions compared to control mice. EE increased levels of Bdnf mRNA variant I (Bdnf I) in the amygdala while it reduced levels of Bdnf I in the hypothalamus, hippocampus, prefrontal cortex, parietal cortex, and brainstem. Meanwhile, EE did not significantly alter levels of Bdnf mRNA variants IIc, IV, and VI in all brain regions examined. These findings support the hypothesis that EE diminishes inter-male aggression by altering Bdnf mRNA expression in a transcript variant-specific and brain region-specific manner. Specifically, brain region-specific alterations in Bdnf I expression may partly mediate EE-induced suppression of inter-male aggression.

ID:16165 Treatment of Knee Pain With Motor Stimulation

Knee pain due to osteoarthritis (OA) is common. Existing treatments each have their limitations. Percutaneous motor peripheral nerve stimulation (mPNS) of the knee is a novel minimally invasive procedure that stimulates motor end points leading to muscle contraction associated with the painful joint. We report 2 patients who underwent mPNS for treatment of refractory OA knee pain.
