Der volle Inhalt der QuelleManual wheelchair (MW) still a part of the daily life of people with disabilities. The objective of this thesis is to develop a new MW based on a mechanical approach which quantifies the resistant forces during propulsion with the final aim is designing a new modular manual propulsion system which will equip the FRM. The mechanical approach involves several kinematic parameters like speed, acceleration, and also dynamics parameters like propulsive force, rolling resistance, and air resistance, to quantify the resistant load which will subsequently be used for the biomechanical study as well than for the sizing of the propulsion. The FRM will be optimized for people with motor disabilities and will be able to provide mechanical propulsion that is more ergonomic and therefore less stressful. The ergonomics as well as the new architecture of the FRM are based on a numerical and experimental biomechanical study which was carried out in partnership with the Warsaw’s University of Technology. The wheelchair will also feature a new aluminum frame fitted with a hubless wheels that provides new aesthetics with a better wheel-ground effort's interaction. This study will be therefore structured around three distinct parts; quantification of the resistant load during wheelchair propulsion, biomechanical analysis of the mechanical manual propulsion and finally design of the new manual wheelchair with a new optimized and modular propulsion system
Alberca, Ilona. „Analyse biomécanique des spécificités du badminton fauteuil“. Electronic Thesis or Diss., Toulon, 2024. http://www.theses.fr/2024TOUL1001.
Der volle Inhalt der QuelleThis thesis aims to biomechanically analyze the specificities of wheelchair badminton. The studies involved 16 able-bodied athletes and 19 wheelchair badminton athletes. The able-bodied athletes performed a submaximal speed test, while the wheelchair athletes performed a maximal speed test. Three specific aspects of the discipline were examined: the use of the badminton racket, the direction of propulsion, and the classification of athletes. Several parameters were evaluated, including force, power, propulsion efficiency, speed, acceleration, deceleration, and temporal measures. The results revealed a negative impact of racket use, which complicates the application of forces on the push rim and alters the propulsion pattern. Backward propulsion also negatively affects athlete performance, particularly impacting their speed, acceleration, and deceleration. Furthermore, athletes classified as WH1 showed lower performance compared to WH2 in terms of speed, acceleration, anddeceleration. However, the specificities studied do not appear to interact synergistically, as the results indicate that one parameter does not exacerbate the effect of another. The collected data also highlight the need to revise the current classification process for wheelchair badminton, incorporating more objective measures and considering the creation of a third category of athletes. This work serves as a foundation for the analysis of this sport and for future research that will aim totest various ergonomic solutions to address the difficulties identified in this thesis

Der volle Inhalt der QuelleWheelchairs compensate for motor dysfunctions, and transform bipedal locomotion to the seated position. The upper limbs become the locomotive limbs. This antiphysiological means of locomotion leads to various specific pathologies, which are mainly neurological and osteoarticular. The purpose of this thesis is to make a significant contribution in the field of biomechanics of wheelchair propulsion by developing tools. These theoretical and experimental tools are mechanical modelling of forces during wheelchair moving, an outdoor kinematics analyse system and an outdoor instrumented wheelchair, called CERAHFIT. We show that integrating rolling resistance parameter is essential to get realistic modelling. Our kinematics analyse system use standard video acquisition and a numerical manikin matched on user wheelchair’s pictures to reconstruct users’ movements in three dimensions. This system could be associated with CERAHFIT in order to adding measures of puschrim, footrest, seat and backrest forces and moments. The next step of this study will be acquisitions with disable persons in order to obtain unbiased arguments to assist the choices of wheelchair adjustments and to improve wheelchair conception

The first goal is descriptive: we try to better understand the specificities of the control of an electrical wheelchair. The second goal is normative: the pilot-wheelchair model should define the optimal control mode of the wheelchair in a given situation. This should induce an objective analysis method of the piloting of the wheelchair. The first chapter of the report is devoted to a bibliographical study related to the various pilot-vehicle models. The second chapter describes the design and the validation of our wheelchair driving simulator. The third and the fourth chapters relate to the application of the Crossover models and the OPCM model.

Der volle Inhalt der QuelleThe works described in this thesis relates to the software architecture developed for the VAHM robotized wheelchaire. It is aims at improving the mobility of people with disabilities by using techniques and methods coming from the field of mobile robotics. The optimization of the man-machine system is obtained by attaining a collaboration between the man operator and the machine. The architecture is based on the nature of processed data. It is composed of abstraction levels and distributed process controls. At each level man and machine can cooperate by providing help for action decision or information. Trials realised with the help of able people have allowed to evaluate communication and cooperation abilities of such an architecture

Der volle Inhalt der QuelleA significant portion of mobility solutions for wheelchairs focuses on assisting the user's movement. Most wheelchairs aim to provide a tailored solution that ensures appropriate driving and stability for the user. The Volting project, developed at LISV since 2020, introduces a new research direction: the development of a wheelchair capable of offering enhanced postural mobility for the user based on lateral tilting.The main objective pursued in the Volting project is to propose a reappropriation of the user's body with the imbalance caused by the tilting. In this regard, an initial proposition was made, consisting of a wheelchair capable of tilting laterally in proportion to the user's inclination. This additional freedom of movement provides the user with a greater capacity for bodily gestures, and it is in this context that wheelchair dancing was chosen as the application domain.In this thesis, the Volting prototype was studied from three perspectives: interaction, control, and assistance.Firstly, the interaction between the user and Volting refers to the relationship between the user's trunk inclination and the tilt of the Volting wheelchair. It was analyzed to find an appropriate behavior. Consequently, a model analysis was conducted to study the parameters involved in this interaction. Experiments demonstrated that the use of our model provided the appropriate parameters for correct kinematics.The second focus of this study is on the user's control of the Volting wheelchair. For this purpose, the use of a multi-sensor device called WISP was proposed. This device takes the user's trunk posture or hand position as input commands to control Volting. The implemented control logic allows the user to control the wheelchair with greater freedom in executing gestures. WISP was tested by a professional and an amateur wheelchair dancer, showing their quick adaptation to the device's use and their motivation towards dance practice.The third area of investigation concerns the use of the incline assistant, named "Glissiere" in Volting. This device relies on shifting the user's seat to promote or counteract the lateral tilt of the Volting wheelchair and, consequently, the user's body tilt. To pre-evaluate this solution, experiments showed that users with different morphologies, who were unable to use Volting to its full capacity, could use Volting with the assistance of "Glissiere."

Der volle Inhalt der QuelleThe Powered wheelchairs (PW) allowed many people with motor disabilities to find a suitable mobility, which improved their quality of life. Hence, a vast field of activities has become accessible for them. When prescribing a PW or in a learning phase, however, it is necessary to evaluate the ability of these people to drive a wheelchair. In this context, our goal is to determine relevant parameters to describe the quality of driving on PW for people with disabilities. First, we modeled the pilot-PW system using the OPCM (Optimal Preview Control Model) model proposed by Sharp. This model is based on the preview distance (Dp) of the user during his driving. This distance has been estimated thanks to an eye-tracking system combined with the ViEW 3D simulator of the LCOMS laboratory. A panel of 15 healthy subjects was recruited to drive the PW on a 3D simulator and to validate the OPCM modeling. This distance Dp allows to describe the behavior of the pilot. If this distance is important, it guarantees the tracking trajectory of the OPCM model. Otherwise, the OPCM model diverges. This shows that if the user looks a long part of his future path, he will better anticipate the future control applied to the PW (change of direction, braking, etc.), which allows him to follow his path. In this situation the user has a tracking behavior. In the otherwise, the user’s behavior is rather compensatory. Then, an analysis of preview distance Dp with respect to the different zones of the path (tight slalom, turn, wide slalom), showed that the parameter Dp can be used to differentiate the different driving behaviors related to the different situations of the path. Next, we compared the preview distance between two groups, familiar and novice with regard to the PW driving. The analysis showed that the familiar group has a greater distance value than the novice group. Finally, a last experiment took place at the Rehabilitation Center of Flavigny sur Moselle (54, France). We estimated the preview distance (Dp) for subjects with severe motor impairment, in order to validate the parameter Dp as a performance indicator. A case study analysis was established on five children with disabilities comparing their results with those previously obtained with the healthy subjects

Der volle Inhalt der QuelleThe study of manual wheelchair (MWC) locomotion biomechanics aims at lowering the risk of upper limbs injuries, by optimizing mobility. Several studies have showed that adjusting MWC settings had an impact on MWC mobility. However, the models used in the literature to depict the « user-MWC » and « MWC-floor » interactions had several limitations. Thus, the first aim of this thesis was to develop a musculoskeletal model of the upper limbs allowing to describe the « user-MWC » interaction, by using adapted experimental methods to apply this model. The second aim of the thesis was to implement a mechanical model of the MWC allowing to compute ground reaction forces during locomotion. The final aim of the thesis was to apply a numerical optimisation procedure, including the models developed during the thesis, to optimize MWC settings. The musculoskeletal model developed during the thesis allowed to analyze biomechanics of the upper limbs during MWC locomotion among subjects recruited during experimental sessions. The MWC settings optimization was implemented with the mechanical model developed during the thesis and confirmed the influence of various MWC settings on mobility. Eventually, improvement perspectives for the numerical optimization procedure of MWC settings were explored, based on predictive movement generation with optimal control algorithms

Der volle Inhalt der QuelleIn fields like rehabilitation, sports sciences and ergonomics, the evaluation of the force feasible set (FFS) of the human limbs may help to better understand the human motor abilities. The aim of this thesis was to compare the upper-limb force capacity at the hand predicted by two different kinds of FFS formalism. The first one originating from the robotics field was used to compute the force ellipsoid (FE), scaled force ellipsoid (SFE), force polytope (FP) and scaled force polytope (SFP). For one posture, they are computed from the upper-limb model and hypotheses and data on maximum isometric joint torques. The second one permitted to compute the FFS modeled as a force polytope from a musculoskeletal model (MSFP). All the previously mentioned models were compared with a measured force polytope (MFP). To construct it, the maximum isometric forces exerted at the hand were assessed in twenty-six directions of the Cartesian space. Then, the MSFP was applied to the manual wheelchair propulsion in order to characterize the forces applied on the handrim during this task and a new evaluation index of postural performance (IPP) was also introduced

Der volle Inhalt der QuelleIn France, more than 2 children out of 1000 are born with "Cerebral Palsy", caused by lesions on the cerebral level. This non-progressive pathology causes disorders of motor skills and the attentional process. Some of these children do not have access to the electric wheelchair for safety reasons, as they may make dangerous steering mistakes. They do not have access to autonomy and move in manual wheelchair pushed by a third person. However, today the medical studies of the field point on the need for accession to autonomous displacement, essential for personal development, intellectual and social participation of any person, disabled or not. This thesis aims to develop an adaptable optronic system, transforming a classic electric wheelchair into a semi-autonomous wheelchair. This means that the user keeps control of the direction and speed of the chair, but that sensors can inhibit controls that prevent from falls (sidewalks, stairs, etc.) or frontal collisions. The priority is placed on a device consisting of a combination of sensors that can adapt to the different existing models of wheelchair respecting their initial size. All sensors used or designed for the intended purpose, must maintain their performance in all environments (indoor, outdoor, strong sunlight, wet tar, etc.). The total energy consumption must not exceed a few Watts. For frontal collision avoidance and door entry, we have developed a solution combining for each side of the chair a double infrared sensor and an ultrasonic sensor. The infrared sensors, developed in-house, are designed to have cylindrical protection zones, making it possible to effectively detect the passages cleared of the size of the chair and to manage the angles thanks to the double sensor. The ultrasonic sensor is designed to handle dark fine end-face obstacles that can escape infrared sensors. The control of the flatness of the floor and therefore of the anti-tip, a LiDAR triple laser beams has been developed to protect each wheel with 1 m of anticipation. The data of the various sensors will be coupled to the odometry of the chair to make decisions on orders. The sensors are designed to provide sufficient anticipation up to 3 km/h. This is a low speed, but suitable for users who in the current context are not allowed to drive.Real-life tests in various climatic situations are carried out. Solutions are sought for chaotic floors or when the user moves a lot on the chair

Der volle Inhalt der QuelleBecause they seemingly have to make the dialog work as well as to construct theperformance, because they seem to encroach upon the director’s grounds and yet cannot level with the magic of the actual staging, because they are not a real piece of literature nor do they belong to the show, the stage directions have long been overlooked by theater studies. In the past few years, a mild interest has arisen. On the one hand, linguists describe in a synchronic fashion the generic features of this particular type of discourse. On the other hand, critics wish to seize the specificity of each author’s stage directions, with an emphasis on the breaches of their theoretical functional purity.In this thesis, we intend to go beyond this fragmented approach by offering an overall poetics of stage directions and, in order for it to carry meaning, weight and nuance, we choose to base it on history and, specifically, on XXth century theater, from Villiers to Koltès, an enlarged century, deeply rooted in the XIXth and already glancing at the XXIst. It is then that stage directions redefine themselves as a result of the advent of the director and his coming to power ;it is then that they spectacularly travel out of joint but appear, nonetheless, incapable or unwilling to get rid altogether of their fundamental usefulness. Unequivocally, they prove to be a form of speech limping “one foot in duty, on foot in desire”, an icarian discourse reconciling what is theoretically opposed.This study starts with the format of the stage directions, their territory, their enunciation (i.e. the exact role they play in the dramatic communication), their graphic characteristics (punctuation, typography, lay-out). Then, we investigate the very fabric of stage directions writing, the perpetual tension between the pact that rules them (clarity, economy) and a fundamental drive to become something else (to become stage, to become poem, to become novel…)

Der volle Inhalt der QuelleIn this thesis, a methodological and algorithmic approach is proposed, for visual intention recognition based on the rotation and the vertical motion of the head and the hand. The context for which this solution is intended is that of people with disabilities whose mobility is made possible by a wheelchair. The proposed system is an interesting alternative to classical interfaces such as joysticks and pneumatic switches. The video sequence comprising 10 frames is processed using different methods leading to the construction of what is referred to in this thesis as an “intention curve”. A decision rule is proposed to subsequently classify each intention curve. For recognition based on head motions, a symmetry-based approach is proposed to estimate the direction intent indicated by a rotation and a Principal Component Analysis (PCA) is used to classify speed variation intents of the wheelchair indicated by a vertical motion. For recognition of the desired direction based on the rotation of the hand, an approach utilizing both a vertical symmetry-based approach and a machine learning algorithm (a neural network, a support vector machine or k-means clustering) results in a set of two intention curves subsequently used to detect the direction intent. Another approach based on the template matching of the finger region is also proposed. For recognition of the desired speed variation based on the vertical motion of the hand, two approaches are proposed. The first is also based on the template matching of the finger region, and the second is based on a mask in the shape of an ellipse used to estimate the vertical position of the hand. The results obtained display good performance in terms of classification both for single pose in each frame and for intention curves. The proposed visual intention recognition approach yields in the majority of cases a better recognition rate than most of the methods proposed in the literature. Moreover, this study shows that the head and the hand in rotation and in vertical motion are viable intent indicators

This joystick will have to be implemented on a "smart" wheelchair provided with telemetric sensors. The force feedback is calculated according to the proximity of the obstacles and assists the user, without forcing him, to move towards the free direction. The first chapter of the report is a state of the art on the smart wheelchairs, on the control modes in teleoperation, on the haptic interfaces in robotics and on the modelling of piloting tasks. The second chapter describes the design of a simulator of wheelchair piloting intended to test new functionalities. The third and final chapter relates to a set of experimental results aiming at concluding on the interest of the force feedback for wheelchair piloting and on the choice of its calculation algorithm. The parameters tested are in particular the configuration of the environment (corridor, doors passages, free space …) and the kinematics of the wheelchair (front-wheel drive, rear-wheel drive)

Der volle Inhalt der QuelleThe idea of disability usually implies an unfortunate difference towards a desirable model. However, some sides of the culture stemming from disability studies and activists movements suggest that disabilities aren’t only inpairments. They generate norms too. This thesis proposes the surmise of disability as a creative matter. The survey focuses on men in wheelchairs but we also pay attention to some facets of french disability associations. Able-bodied schemas are pregnant in these both points. However, in the ordinary run of things, some disabled people create social norms which can be shared but they think these are illegitimate norms. The resources to understand the experience of disability regardless of the meanings derived from the standard body are found. But they aren’t visible much in France. Then french people can’t use them in order to build their gender lives and snatches of creation stay on the threshold of instituted meanings. The messages of french associations are dependant on dominant able-bodied language. Consequently, the theme of disability lose his own affirmative and conflicting dimensions

In this thesis a dynamic model for power wheelchairs including longitudinal and lateral slip effect that takes place while driving under non-normal conditions is presented. The system model developed consists of three main parts: body model, wheel model, and tire model. All these parts will be derived separately and will be in integrated into one global model. The effectiveness of the proposed method is verified by the simulation and the practical experiments. Also, the driver behaviour model is presented. The proposed behaviour model is based on the generalized force. In the proposed model, we assume that the driver when drives wheelchair to a certain target in this trajectory is subjected many forces, the summation of these forces act upon a driver cause it to accelerate or decelerate and change this direction continually while moving. The simulation results show that the proposed model shows realistic behaviour for the investigated scenarios

Der volle Inhalt der QuelleThe development of Paralympics has done a lot for a more positive image of handicap and has opened up new opportunities for the practice of disability sport, known to be highly beneficial for the physical and psychological health of disabled people. Conducted in close partnership with a high level tennis player, this study focuses on the influence of the wheelchair settings on its behavior in order to adapt this behavior to wheelchair tennis playing. The study first highlighted the forces of resistance to straight line or rotating wheelchair movements, thanks to mechanical models validated by experiments. Then, the inertial parameters of the seated player's body segments were assessed by adapting a volumic model to the sitting position, and his propulsion at maximal velocity was studied, in order to understand the effect of the seat fore-and-aft position on this movement. Then, an experimental study proved the major influence of the center of gravity position on free rotation, which was modelized too.In a nutshell, this research work has led to a better understanding of the effects of the wheelchair settings on its behavior, its results have allowed to modify various settings on our partner's wheelchair and can be used as a basis for future wheelchair conception/design. They have also proved useful for conventional wheelchairs and in the meantime, our tennis player partner has become wheelchair tennis world champion…

Der volle Inhalt der QuelleIntroduction. L’entrainement aux habiletés requises en fauteuil roulant manuel (FRM) mené par un pair est efficace pour améliorer ces habiletés et l’auto-efficacité. Peu d’information est disponible sur l’entrainement dans la communauté. Ainsi, le premier objectif de ce mémoire consiste à réaliser une synthèse des connaissances sur les effets des interventions de réadaptation impliquant des pairs. Le second objectif consiste à évaluer les effets de Roulez avec confiance, un entrainement aux habiletés en FRM mené par un pair dans la communauté, et à explorer l’expérience des participants au programme. Méthode. Une revue systématique des écrits a été menée. Ensuite, une étude à devis mixte parallèle avec trois temps de mesure a été réalisée. Des questionnaires sur la participation sociale (Wheelchair outcome measure), l’auto-efficacité (Wheelchair use confidence scale for manual wheelchair users), les habiletés en FRM (Wheelchair skills test questionnaire) et la qualité de vie (Satisfaction with life scale) ainsi qu’une entrevue semistructurée ont été complétés. Une analyse non-paramétrique de données longitudinales et une analyse de contenu thématique ont été réalisées. Résultats. Treize études ont été identifiées : certaines menées par des pairs et d’autres par des professionnels. Dix-neuf utilisateurs de FRM (45±12 ans) ont participé au programme. Une différence statistiquement significative (p<0,0001) a été identifiée pour toutes les variables sauf la qualité de vie (p=0,687). Les gains se sont maintenus après trois mois. Les thèmes émergeant des entrevues sont : 1) L’influence de mon passé ; 2) Composantes du programme : toucher à la surface ; 3) Une expérience sociale positive ; 4) Comment l’environnement physique a façonné le programme ; 5) Apprendre plus que des habiletés ; 6) Les émotions provoquées par le programme. Conclusion. Davantage d’études sont nécessaires pour déterminer les effets sur la mobilité et la participation des interventions impliquant des pairs. Roulez avec confiance apporte des bénéfices aux utilisateurs de FRM
Introduction. A peer-led wheelchair skills training is effective to increase wheelchair skills and self-efficacy. Few information is available on wheelchair training in the community. The first objective was to synthesize knowledge on the effectiveness of peer-based rehabilitation interventions among adults with mobility disabilities. The second objective was to evaluate the effects of Roulez avec confiance, a peer-led community-based wheelchair skills training, on community-dwelling manual wheelchair users and to explore their experience in the program. Methods. First, a systematic literature review was conducted. Second, a parallel mixed design was used with measurements before, after and 3 months after the program. Validated questionnaires on social participation (Wheelchair outcome measure), manual wheelchair self-efficacy (Wheelchair use confidence scale for manual wheelchair users), manual wheelchair skills (Wheelchair skills test questionnaire), and quality of life (Satisfaction with life scale) were administered. A semi-structured interview on users’ experience was conducted. Nonparametric analysis of longitudinal data and thematic content analysis were done. Results. Thirteen peer-based studies were identified including peer-led and professional-led studies. Nineteen manual wheelchair users (45±12 years) participated in the peer-led program. There was a statistically significant increase (p<0.0001) in all outcomes except quality of life (p=0.687). Gains were maintained after three months. Main themes identified were: 1) The influence of my background; 2) Components of the program: Scratching the surface; 3) A positive social experience; 4) How the physical environment shaped the program; 5) Learning more than skills; 6) Emotions triggered by the program. Conclusion. Further research on the effects of peer-based interventions on mobility and participation is warranted. Roulez avec confiance is a relevant intervention to deliver peer-led community-based wheelchair skills training to community-dwelling manual wheelchair users.

Der volle Inhalt der QuellePeople with Disabled Mobility (PDM) often suffer from limitation during locomotion. Several tools are at their disposal to help and assist them in their displacement, specifically the electric or the Manual Wheelchair (MW). This thesis works focuses on the Human-MW-Interaction (H-MW-I) subject to determine elements predictors of forthcoming displacement with a view of aid to locomotion. Understanding (H-MW-I) is a current challenge to improve the displacement and optimize the performance as well as comfort, by minimizing fatigue and injury risk. In order to enhance understanding and even improving the (H-MW-I), a set of studies focusing on Biomechanics and electromyographic analysis of anticipation elements of the Manual Wheelchair Initiation Displacement (MW-ID) was performed during the thesis works. This set of studies focuses on i) Anticipatory Muscular Activities (AMA) in the sitting position to question the predictability of the movements in relation to its prior parameters; ii) evolution of muscular patterns and pressures on the seat when MW-ID to question the adaptability or specificity of the initial parameters during various displacements using MW in healthy subjects ; iii) evolution of muscular patterns and pressures on the seat when MW-ID in spinal cord injury subjects and; iv) multivariate analysis of the MW-ID parameters. The CNS presents an important capacity of adaptability to the forthcoming movement by adjusting motor commands to the global physiological condition of the subject. This adaptability has led to significant percentages prediction and it can be saved through macroscopic elements to envisage help systems to displacement for PDM

Der volle Inhalt der QuelleIntroduction. Displacement capacities and possibilities in manual wheelchair (MWC) are strong determinants of social and occupational integration of MWC users. Objectives. Improve the knowledge of the strains involved by displacement in MWC through 2 studies; the first one to identify habits and difficulties of MWC users. The second one, induced by the results of the first one, has assessed the poorly known cardiac, energetic, muscular and subjective strains of the displacement of MWC users on a cross slope. Methods. The first study was a survey answered by 118 paraplegics habitual MWC users. The second one, a laboratory study conducted with 25 paraplegic men, includes 2 tests: a sub maximal arm-cranking test and a 300 m propulsion test with 8 conditions combining 4 cross slopes (0, 2, 8 et 12%) and 2 velocities (0,97 m.s-1 and a "comfortable" chosen one). Results. The first study shows an adverse environment, with many places unreachable without help and disturbances, like cross slope, which hinders users' displacements. The second study demonstrates the increases of cardiac, energetic, muscular and subjective strains with cross slope. Differencies between 0 and 2% cross slopes are low but quantified. Displacement on a 12% cross slope is very difficult. The balance of muscles activities is changing at 2% cross slope. The injury level makes deep changes in the displacements strategies and in as well perceived as measured strain levels. Discussion-Conclusion. Effects of cross slope are perceived for as low as 2% and onwards values. They are high and deleterious at 8%. This work allows to construct a model of cross slope strains which confirms that the regulatory 2% cross slope limit is well chosen because it allows most MWC users to move without help and remain active
