Abstract:
In oncology research, while xenograft tumor models are easily visualized and humane endpoints can be clearly defined, metastatic tumor models are often based on more subjective clinical observations as endpoints. This study aimed at identifying objective non-invasive criteria for predicting imminent distress and mortality in metastatic lung tumor-bearing mice. BALB/c and C57BL/6 mice were inoculated with CT26 or B16F10 cells, respectively. The mice were housed in Vium smart cages to continuously monitor and stream respiratory rate and locomotion for up to 28 days until scheduled euthanasia or humane endpoint criteria were met. Body weight and body temperature were measured during the study. On days 11, 14, 17 and 28, lungs of subsets of animals were microCT imaged in vivo to assess lung metastasis progression and then euthanized for lung microscopic evaluations. Beginning at day 21, most tumor-bearing animals developed increased respiratory rates followed by decreased locomotion 1–2 days later, compared with the baseline values. Increases in respiratory rate did not correlate to surface tumor nodule counts or lung weight. Body weight measurement did not show significant changes from days 14–28 in either tumor-bearing or control animals. We propose that increases in respiratory rate (1.3–1.5 X) can be used to provide an objective benchmark to signal the need for increased clinical observations or euthanasia. Adoption of this novel humane endpoint criterion would allow investigators time to collect tissue samples prior to spontaneous morbidity or death and significantly reduce the distress of mice in the terminal stages of these metastatic lung tumor models.

Abstract:
L’invention de l’aéroplane est une solution au problème du vol humain. Ce moyen de locomotion, étant « plus lourd que l’air », peut s’y diriger contrairement au ballon qui dépend des courants aériens. L’ère des pionniers de l’aviation débute à l’extrême fin du XIX e siècle pour s’achever en 1909. Elle a pour théâtre la France et les États-Unis. Ce sont en effet deux frères américains, Wilbur (1867-1912) et Orville (1871-1948) Wright, qui parviennent les premiers à exécuter de véritables vols en 1903. Cette aviation naissante va susciter l’intérêt des militaires français qui possèdent une expérience dans le domaine du « plus léger que l’air » depuis plus d’un siècle.

Abstract:
The latest technical and interaction advancements within the virtual reality (VR) field have marked a new era, not only for VR, but also for VR locomotion. In this era, well-established, prevalent VR locomotion techniques are mostly used as points of comparison for benchmarking of new VR locomotion designs. At the same time, there is the need for more exploratory, comparative studies of contemporary VR locomotion techniques, so that their distinguished interaction aspects can be documented and guide the design process of new techniques. This article presents a comparative, empirical evaluation study of contemporary and prevalent VR locomotion techniques, examining the user experience (UX) they offer. First, the prevalent VR locomotion techniques are identified based on literature, i.e., walking-in-place, controller/joystick, and teleportation. Twenty-six adults are enrolled in the study and perform a game-like task using the techniques. The study follows a mixed methods approach, utilising the System Usability Scale survey, the Game Experience Questionnaire, and a semistructured interview to assess user experiences. Results indicate that the walking-in-place technique offers the highest immersion but also presents high levels of psychophysical discomfort. Controller/joystick VR locomotion is perceived as easy-to-use due to the users’ familiarity with controllers, whereas teleportation is considered to be effective due to its fast navigation, although its visual ‘jumps’ do break the users’ sense of immersion. Based on the interviews, the users focused on the following interaction dimensions to describe their VR locomotion experiences: (i) immersion and flow, (ii) ease-of-use and mastering, (iii) competence and sense of effectiveness, and (iv) psychophysical discomfort. The study implications for VR locomotion are discussed, along with the study limitations and the future direction for research.

Abstract:
Virtual reality applications, especially in entertainment and training, require environments populated with multiple interacting humans. Whether the virtual humans are controlled by real people or by computer programs, a large portion of their activity will involve locomotion. This paper presents VRLOCO, a “locomotion engine” designed to meet the locomotion requirements of virtual environments. First, VRLOCO is broadly capable; it includes five locomotion primitives—walking, running, lateral stepping, turning around, and backward stepping—and can blend smoothly between primitives during transitions. Second, locomotion control in VRLOCO is simple; controllers drive the locomotion by supplying streams of intuitive positional inputs—desired body center position and facing direction—over time. Finally, VRLOCO is responsive and efficient; it generates locomotion on-line, processing user- or program-generated control inputs and producing new frames at rates greater than 30 Hz. Technically, VRLOCO combines a method for generalizing prototypical locomotion data with algorithms for determining locomotion mode and blending between different modes. The effectiveness of the approach has been tested using several locomotion controllers—programs representing autonomous agents, interactive graphic user interfaces, and a VR input device consisting of a stationary bicycle equipped with optical encoders and a microcontroller.

Abstract:
There is currently no fully natural, general-purpose locomotion interface. Instead, interfaces such as gamepads or treadmills are required to explore large virtual environments (VEs). Furthermore, sensory feedback that would normally be used in real-world movement is often restricted in VR due to constraints such as reduced field of view (FOV). Accommodating these limitations with locomotion interfaces afforded by most virtual reality (VR) systems may induce cognitive demands on the user that are unrelated to the primary task to be performed in the VE. Users of VR systems often have many competing task demands, and additional cognitive demands during locomotion must compete for finite resources. Two studies were previously reported investigating the working memory demands imposed by semi-natural locomotion interfaces (Study 1) and reduced sensory feedback (Study 2). This paper expands on the previously reported results and adds discussion linking the two studies. The results indicated that locomotion with a less natural interface increases spatial working memory demands, and that locomotion with a lower FOV increases general attentional demands. These findings are discussed in terms of their practical implications for selection of locomotion interfaces when designing VEs.

Abstract:
La perte d’habitat due à l’activité humaine est une menace qui affecte tous les primates à Madagascar. Les lémuriens, primates arboricoles, ont des réponses variées face au changement de leur habitat. La présente recherche vise à déterminer le lien entre la dégradation forestière, la masse et les caractères morphologiques des lémuriens nocturnes de Menabe Sud : Lepilemur ruficaudatus et Microcebus murinus. L’étude a été effectuée dans cinq sites dont deux sites sont des forêts primaires et trois autres sont des forêts perturbées. La capture et la mesure des caractères morphologiques des lémuriens ont été réalisées entre novembre et décembre 2014, puis entre juillet et septembre 2015. Des parcelles botaniques (5m x 5m) ont été utilisées pour décrire les caractéristiques des sites dont l’abondance des arbres, le diamètre à hauteur de poitrine ou la hauteur et le diamètre de la couronne. La masse de M. murinus n’était pas influencée par la saison de capture (P > 0,05), mais elle variait avec le sexe (P < 0,005) et le site (P < 0,001). Tous les caractères morphologiques de M. murinus dans les deux forêts primaires étaient similaires (P > 0,05). Par contre, dans les forêts perturbées, les femelles de M. murinus étaient plus lourdes et avaient des corps plus longs que les mâles (P < 0,05). La masse et la longueur du corps de L. ruficaudatus entre les différents sites étaient similaires (P > 0,05). Comparé à L. ruficaudatus, M. murinus répondrait advantage à la dégradation forestière. Comprendre l’étendue de la réponse morphologique des lémuriens face à la dégradation de leur habitat pourrait être utilisé comme outil pour prioriser leur conservation.
 English Abstract
 Forest structure effects primate morphology because it determines the availability and characteristics of resources, such as substrates for locomotion, sleeping trees, and trees food. However, forest degradation may alter environmental condition of habitats and influence lemur behavior and morphology. We evaluated the links between forest degradation, lemur body mass, and lemur morphometric. We surveyed red-tailed sportive lemurs (Lepilemur ruficaudatus) and gray mouse lemurs (Microcebus murinus) in the dry, deciduous forest of southern Menabe, Morondava, Madagascar. The study was conducted in the dry season in 2014 (November–December) and 2015 (July– September). Lemur captures were conducted in five forest sites: two primary forest and three disturbed forest. Sherman and Tomahawk style traps were used to capture mouse lemurs. We conducted three capture sessions in site B in 2014 and three capture sessions for each site in 2015, for a total of 5616 night traps. During each capture session, 80 Sherman traps and 24 Tomahawk traps were installed for three consecutive nights. To capture the red-tailed sportive lemur, we used a gun (Dan Inject Model JM air rifle) with a tranquillizer dart to immobilize the animal. We collected morphometric measurements from 232 mouse lemurs and 31 red-tailed sportive lemurs. Botanic plots (5m x 5m) allowed us to characterize the forest characteristics: tree diameter at breast height (DBH), tree height, tree abundance, tree crown height and diameter. Tree abundance with DBH ≥ 5 cm and trees diversity varied significantly between sites (P < 0.001). Mouse lemur body mass did not vary with seasonality of the capture (P > 0.05). For mouse lemurs, all morphometric from two populations in the pristine forest were similar (P > 0.05). Mouse lemurs in one disturbed habitat had greater body length and body mass than mouse lemurs in the pristine forest (P < 0.05). The difference may be linked with fruit abundance of two trees species (Tamarindus indica and Ziziphus mauritiana) and more insect availability in the disturbed site. In the altered habitat, mouse lemur females had longest body size and heavier than males (P < 0.05). Red-tailed sportive lemur body mass and length did not change between sites (P > 0.05). Our study is consistent with the hypothesis that lemur morphometric and body mass may change with forest degradation in southern forest of Menabe. Additionally, the range of the response varies between species and sex: mouse lemurs had a wider reaction norm to the habitat disturbance than did red-tailed sportive lemurs. Mouse lemurs may have higher ecological flexibility and tolerance for forest changes, specifically the alteration of forest habitats. Understanding how lemur morphology responds to habitat disturbance may be used as a tool to prioritize lemur conservation.

Abstract:
Notre motivation est de comprendre la locomotion humaine pour un meilleur contrôle des systèmes virtuels (robots et mannequins). La locomotion humaine a été étudiée depuis longtemps dans des domaines différents. Nous considérons la locomotion comme le déplacement d'un repère attaché au corps humain (direction et orientation) au lieu de la trajectoire articulaire du corps complet. Notre approche est basée sur le fondement calculatoire de la locomotion humaine. Le but est de trouver un modèle qui explique la forme de la locomotion humaine dans l'espace. Pour ce faire, nous étudions tout d'abord le comportement des trajectoires au sol pendant la locomotion intentionnelle. Quand un humain marche, il met un pied devant l'autre et par conséquence, l'orientation du corps suit la direction tangente de la trajectoire. C'est ce qu'on appelle l'hypothèse de comportement nonholonome. Cependant, dans le cas d'un pas de côté, l'orientation du corps n'est plus semblable à la direction de trajectoire, et l'hypothèse n'est plus valable. Le comportement de la locomotion devient holonome. Le but de la thèse est de distinguer ces deux comportements et de les exploiter en neuroscience, robotique et animation graphique. La première partie de la thèse présente une étude qui permet de déterminer des configurations de comportement holonome par un protocole expérimental et par une fonction qui segmente les comportements nonholonomes et holonomes d'une trajectoire. Dans la deuxième partie, nous établissons un modèle unifiant comportements nonholonomes et holonomes. Ce modèle combine trois vitesses générant la locomotion humaine : tangentielle, angulaire et latérale. Par une approche de commande optimale inverse nous proposons une fonction multi-objectifs qui optimise des trajectoires calculées pour les rendre proches des trajectoires humaines naturelles. La dernière partie est l'application qui utilise les deux comportements pour synthétiser des locomotions humaines dans un environnement d'an imation graphique. Chaque locomotion est caractérisée par trois vitesses et est donc considérée comme un point dans l'espace de commande 3D (de trois vitesses). Nous avons collecté une librairie qui contient des locomotions de vitesses différentes - des points dans l'espace 3D. Ces points sont structurés en un nuage de tétraèdres. Quand une vitesse désirée est donnée, elle est projetée dans l'espace 3D et on trouve le tétraèdre qui la contient. La nouvelle animation est interpolée par quatre locomotions correspondant aux quatre sommets du tétraèdre. On expose plusieurs scénarios d'animations sur un personnage virtuel.

Abstract:
L'objectif de ce travail est de fournir quelques éléments de compréhension sur les règles d'organisation de l'activité locomotrice chez l'homme. Son originalité réside dans le fait d'analyser la locomotion humaine dans ses composantes (sensori)motrice et cognitive : ainsi la locomotion est considérée et analysée comme l'activité coordonnée des membres inférieurs combinée à des stratégies de planification communes à l'ensemble des mouvements orientés vers un but spatial. Deux niveaux de description de la locomotion sont pris en compte, l'analyse des processus aboutissant à la formation du pas et ceux liés à la génération de la trajectoire locomotrice. Les effets propres et conjoints du mode et de la vitesse de locomotion, ainsi que de la géométrie des trajets, sur la régulation de l'activité locomotrice, sont étudiés au moyen (principalement) de l'analyse cinématique mais également électromyographique et vidéooculographique. Les origines de certains invariants cinématiques de la locomotion humaine sont étudiées pour ces deux niveaux d'analyse et la caractérisation des mouvements du regard et du corps lors des<br />changements de direction de marche est réalisée. Enfin, quelques approches et principes particulièrement intéressants, comme le principe de segmentation et celui d'optimalité, sont discutés dans le cadre général de l'étude expérimentale et de la modélisation des processus de génération et de contrôle des trajectoires locomotrices.

Abstract:
L'ensemble de ces travaux s'intéresse aux problèmes fondamentaux poses par les capacités d'adaptation intentionnelle de la locomotion, qui associées aux capacités d'adaptation reflexe, confèrent son efficacité a ce comportement. Afin de dégager dans le comportement des facteurs élémentaires d'origine synergique et/ou dynamique de facteurs cognitifs d'origine volontaire, nous avons pose a l'automatisme des problèmes a priori non solubles par une simple modulation de son activité. Le travail expérimental se subdivise en trois parties. La première série d'expériences porte sur des modifications des conditions dynamiques (ajout de masses ou de forces externes) affectant sélectivement l'une ou l'autre des phases du cycle. La deuxième série d'expériences porte sur la dissociation volontaire d'une relation caractéristique liant amplitude et fréquence d'enjambée. La troisième série d'expériences porte sur les bases afférentielles du contrôle locomoteur, nous envisageons ici une éventuelle contribution spécifique du flux optique. Les capacités de contrôle intentionnel de la locomotion consistent essentiellement a maitriser l'amplitude d'enjambée pour l'adapter aux aléas du terrain tout en gardant le contrôle de la vitesse et de la direction du déplacement. L'idee principale qui ressort de ce travail est que le réglage intentionnel de l'activité synergique permet essentiellement la production d'un rythme; si l'amplitude automatiquement associée a ce rythme n'est pas adaptée a l'environnement elle est modulée, dans les limites fixées par les propriétés physiques du système effecteur, par une commande indépendante d'allongement ou de raccourcissement de l'enjambée.

Abstract:
Le travail de cette thèse a pour objectif de questionner le modèle symétrique de la locomotion chez le sujet sain adulte par une approche fonctionnelle et biomécanique. Le premier travail expérimental investit les différentes méthodes statistiques afin de mesurer quantitativement la taille de l'asymétrie lors de la marche. Les résultats montrent l'intérêt de la méthode de l'effect size pour dépasser les limites des outils traditionnels de mesure. Cette méthode apparaît sensible aux augmentations de l'asymétrie de marche chez des groupes normaux et hémiplégiques. De plus, elle permet de normaliser l'amplitude des différences bilatérales par la variabilité des données mesurées, facilitant ainsi l'interprétation de la grandeur de l'asymétrie. La seconde contribution personnelle a testé une classification inédite des membres inférieurs pour l'étude de l'asymétrie. Les résultats montrent deux types de profil asymétrique dans une logique de propulsion et de freinage. La première stratégie (70,8% de sujets) consiste à différencier la jambe la plus propulsive de la jambe la plus freinatrice. La seconde (25% des sujets) se caractérise par un membre inférieur qui réalise à la fois les actions de propulsion et de freinage les plus intenses. Les résultats cinétiques et cinématiques légitiment l'hypothèse de partage de fonctions entre les membres inférieurs. La dernière étude vise à démontrer l'aspect adaptatif de l'asymétrie de marche lors d'un protocole présentant des contraintes de nature propulsive et frénatrice. L'augmentation de l'asymétrie dans ces conditions perturbatrices montre son aspect stratégique dans le contrôle de la vitesse de déplacement et démontre son caractère fonctionnel<br>This work aims to challenge the symmetry model of human locomotion control by biomechanic and functional analyses. The first study tested the effect size statistic for quantifying asymmetry in relation to traditional methods. Results showed that effect size method was beneficial because asymmetry was represented in standard deviation units allowing a more accurate description of it. Comparison between subjects having marked gait asymmetry (patients with hemiparesis) and subjects who appear to have a "normal" gait pattern showed the reliability of this method for dectecting increase of asymmetry size in gait. The second study was designed to assess the existence of a preferential lower limb for forward propulsion and braking. Results highlighyed two forms of asymmetry behaviour : 70. 8% of the participants displayed a different more propulsive limb from more braking limb, whereas 25% used the same leg as the more peopelling and the more braking one. Kinetic and kinematic analyses suggested a functional division of tasks between the two lower limbs. The last study aims to test the functional strategy of asymmetry by constraining subjects to keep the same velocity of displacement despite acceleration and braking perturbations. The increase in the asymmetry size showed that asymmetry is a real behavioral strategy for the velocity control of locomotion

Abstract:
La locomotion résulte de phénomènes posturaux complexes qui nécessitent le fonctionnement intégré des membres antérieurs, postérieurs et du tronc. Le maintien d’un équilibre dynamique durant la propulsion vers l’avant ne peut être réalisé que parce qu’il existe des processus internes de coordination entrez les réseaux nerveux qui commandent la contraction rythmique de ces différents niveaux. Alors que la grande majorité des études sur la locomotion porte sur le fonctionnement des membres postérieurs, notre intérêt s’est focalisé sur le rôle du tronc et l’organisation des réseaux neuronaux spinaux sous-tendant son activité en coordination avec les membres. Trois approches différentes ont été réalisées : (1) cinématique permettant de visualiser dans l’espace les mouvements du rat de sa naissance à l’âge du sevrage ; (2) électrophysiologique sur préparation de moelle épinière isolée in vitro centrée sur les réseaux spinaux responsables de l’activité motrice chez le rat nouveau-né ; (3) électromyographique pour déterminer le patron d’activation des muscles axiaux chez l’homme. Nos résultats montrent qu’au cours du déplacement, le tronc se courbe rythmiquement chez le rat et l’homme. Chez le rat, le développement modifie la sortie motrice en amplitude et en vitesse d’exécution principalement. La courbe du tronc serait due à la propagation séquentielle de l’onde motrice le long de la moelle épinière. Nos données suggèrent également que les réseaux responsables de la propagation métachronale des patrons moteurs au cours de la locomotion correspondent à ceux observés chez les invertébrés ou vertébrés inférieurs et seraient donc conservés à travers l’évolution<br>Locomotion involves complex synergistic postural regulation requiring the integrated functioning of all the body musculature, including hind- and forelimb, trunk and neck muscles. Dynamic equilibrium during forward locomotion is preserved by internal process of coordination between neuronal that drive rhythmic contraction of this muscles. Although numerous studies have focused on understanding how the CNS controls hindlimb movements, very few studies has been devotes to understanding the functioning of neural networks that activate trunk muscles in coordination with limb movements. To answer approach these question three main approaches have been used. (1) a kinematic approach allowing to visualize from birth to weaning day, the rat movements in a 3-D environment ; (2) an electrophysiological approach on an in vitro isolated spinal cord preparation based on spinal neuronal networks responsible for motor activity in the newborn rat ; (3) an electromyographic approach to determine the pattern of activity of axial movements in human. Our results show that there is a rhythmic sequential change in trunk curvature during the step cycle. In rats, development modifies the amplitude an velocity of the motor output. The trunk bending could be related to the sequential propagation of the motor wave along the spinal cord. Our data suggest that the networks responsible for metachronal propagation of motor patterns during locomotion may correspond to those observed in vertebrates or lower vertebrates, and thus are highly conserved

Abstract:
Abstract This paper introduces a magneto-electroactive endoluminal soft (MEESo) robot concept, which could enable new classes of catheters, tethered capsule endoscopes, and other mesoscale soft robots designed to navigate the natural lumens of the human body for a variety of medical applications. The MEESo locomotion mechanism combines magnetic propulsion with body deformation created by an ionic polymer-metal composite (IPMC) electroactive polymer. A detailed explanation of the MEESo concept is provided, including experimentally validated models and simulated magneto-electroactive actuation results demonstrating the locomotive benefits of incorporating an IPMC compared to magnetic actuation alone.

Abstract:
Stable and reliable legged locomotion is critical for humans and humanoid robots. In the study of legged locomotion, simple models consisting of point-mass bodies and massless legs with telescoping actuators have been insightful. Several variants have been used, including the telescoping leg as a general force actuator [1], a simple passive linear or nonlinear spring [2], and a spring in series with a general force actuator [3]. These models serve as analogs that simplify the problem of understanding the mechanics of legged locomotion of real animals. One of defects of these simple models is the representation of the body by a point mass. Hence, trunk stabilization is not addressed. Nevertheless, this is a major problem in human and humanoid locomotion. In this study we propose a novel decoupled strategy to stabilize the trunk. First, we describe how this decoupled strategy works theoretically. Then, we present a case study based on the CT-SLIP model. Finally, we summarize the work and its expected impacts.

Abstract:
Elastically suspending a load with a compliant suspension system can increase the energy efficiency of legged locomotion and load carrying in humans, animals, and robots. In prior work, we developed a simple linear model from first principles and showed that elastically-suspended loads reduce the energy cost and stability of locomotion. In this paper, we expand on this model by adding flight phases, transforming it into a nonlinear hybrid system that is a more realistic representation of human hopping and high-speed locomotion more generally. The addition of flight phases causes a counterintuitive shift in the behavior of the double-mass coupled-oscillator system. With the addition of flight phases, the tuning of the elastic load suspension becomes more critical in order to reduce the energy cost of human hopping. Elastically-suspended loads also increased the overall system stability compared to rigidly-attached loads when the system exhibits flight phases. Therefore, under certain conditions, a human hopping with an elastically-suspended load can exhibit increased energy efficiency and stability compared to a rigidly-attached load. This study will help improve our understanding of elastically-suspended loads and could enable the design of tuned suspension systems for load carrying.

Abstract:
Abstract Robotic exoskeletons can provide powered locomotor assistance and rehabilitation to persons with mobility impairments due to aging and/or physical disabilities. Here we present the preliminary development and systems integration of T-BLUE — a modular, bilateral robotic hip-knee exoskeleton with 3D-printed backdriveable actuators. We retrofitted commercially available passive postoperative orthoses with open-source 3D-printed actuators to minimize cost and improve accessibility. The actuators are of quasi-direct drive design with high-torque density brushless DC motors and low gearing (15:1 transmission ratio) for low output impedance and high backdrivability, therein allowing for energy-efficient and dynamic human-robot physical interaction and legged locomotion. The modular design allows the exoskeleton to be customized and adapted to different users (e.g., persons with lateral vs. bilateral mobility impairments) and different hip-knee joint configurations. The goals of this preliminary study were to describe our experience with regards to the repeatability of the open-source 3D-printed actuators in engineering practice and the feasibility of integrating the actuators into wearable robotics hardware. This qualitative research serves as a first step towards using the robotic exoskeleton to support the development and testing of novel controller designs and rehabilitation protocols for different locomotor activities of daily living. We are especially interested in populations that could benefit from partial locomotor assistance such as older adults and/or persons with osteoarthritis. Future research will involve benchtop testing to quantitatively evaluate the actuator performance in terms of dynamics and energy-efficiency.

Abstract:
Predicting the energy costs of human travel over snow can be of significant value to the military and other agencies planning work efforts when snow is present. The ability to quantify, and predict, those costs can help planners determine if snow will be a factor in the execution of dismounted tasks and operations. To adjust predictive models for the effect of terrain, and more specifically for surface conditions, on energy costs, terrain coefficients (ƞ) have been developed. By applying knowledge gained from prior studies of the effects of terrain and snow, and by leveraging those existing dismounted locomotion models, we seek to outline the steps in developing an improved terrain coefficient (ƞ) for snow to be used in predictive modeling. Using published data, methods, and a well-informed understanding of the physical elements of terrain, e.g., characterization of snow sinkage (z), this study made adjustments to ƞ-values specific to snow. This review of published metabolic cost methods suggest that an improved ƞ-value could be developed for use with the Pandolf equation, where z=depth (h)*(1 - (snow density (ρ0)/1.186)) and ƞ=0.0005z3 + 0.0001z2 + 0.1072z + 1.2604. This paper provides data-driven improvements to models that are used to predict the energy costs of dismounted movements over snow.

Abstract:
Review question / Objective: This systematic review and meta-analysis aimed to synthesize available randomized controlled trial studies concerning the effects of exercise interventions on fundamental motor skills in children with autism spectrum disorder. Condition being studied: Autism Spectrum Disorder (ASD) is a complicated and highly prevalent neuro-developmental disorder characterized by deficits in social communication, restricted interests, and repetitive behaviors. The CDC reported that the prevalence of ASD was estimated to be 1 in 59 in the United States by 2020. Along with typical symptoms, a couple of studies have indicated that individuals with ASD encounter a variety of challenges, including sleep disturbance, obesity, executive function deficits, physical inactivity, and motor dysfunctions. Fundamental motor skills (FMS) are the unnaturally occurring basic motor learning model of the human body, which are the building blocks for advanced specialized motor skills and for children and adolescents to participate in sports, games, or other context-specific physical activity.FMS falls into three different categories: (a) locomotor skills (e.g., running and hopping), (b) object control skills (e.g., catching and throwing), and balance or stability skills (e.g., balancing and twisting).
