Texto completo da fonteCerebral Palsy is the most common physical disability in early childhood, resulting in multiple disorders, primarily of motor skills. Speech especially can be impacted and deeply affects children’s communicative abilities. The RePliCa software wasdeveloped to improve the efficiency of motor speech therapy. One variable, engagement, has not been fully researched in the field of rehabilitation but has been identified influential for children’s progress. Engagement is presumed to bemalleable and sensitive to environmental changes and therefore could be influenced by the introduction of software in rehabilitation. The first part of this thesis was devoted to its optimization. To this end, a series of experimental studies wereconducted, enabling the integration of a number of features on the interface in order to promote engagement. Once the software was implemented, engagement in rehabilitation was examined in a clinical study. Results showed encouraging results: engagement can be maintained over time. Results are put in perspective using an engagement model framework

Texto completo da fonteThe gait characteristics of patients with hemiparesis are usually assessed during stable, straightline gait. Clinical tests are mostly based on timed performance, although biomechanical gait analysis may be carried out. The analysis of navigational tasks that involve constraints encountered in daily life is necessary to increase understanding of gait deficits. The Timed Up and Go test (TUG) includes oriented gait towards a target, and turning tasks, typical of real-life gait. However, the simple analysis of performance time does not provide sufficient information regarding actual performance of the tasks. The main aim of this thesis was to characterize the locomotor displacements of hemiparetic patients during navigational tasks, such as those involved in the TUG. To this end, we carried out a biomechanical analysis of gait during the three navigational tasks of the TUG (oriented gait to the target, turning and oriented gait to the seat). We analysed the kinematics, stability and locomotor trajectories of patients and healthy subjects. This work is original because it provides a biomechanical characterization of the organization of gait in patients with hemiparesis during navigational tasks, using innovative parameters. The longer performance time in hemiparetic patients, compared with healthy subjects, was related to a decrease in the majority of spatio-temporal and joint kinematic parameters. Moreover, the results showed that oriented gait tasks were controlled by the same parameters in hemiparetic patients and healthy subjects, but in different proportions. In contrast, the turning task was controlled by different, specific parameters. Organizational differences between hemiparetic patients and healthy subjects were also highlighted, namely a lack of stability, slowing during the turn and deviation from the trajectory by the patients. These results suggest that hemiparetic patients use a strategy which is a compromise between stability, trajectory and performance for the optimal achievement of navigational tasks, such as these involved in the TUG. The implications of this work for the clinical management of hemiparetic patients are explained

Texto completo da fontePhysical abilities are directly related to healthy aging. Thus, it is essential to be able to estimate them quickly and simply during clinical routines. In this thesis, we focused on the sit-to-stand transition that is already used in geriatrics and that constitutes a movement in everyday life that becomes more complex for people whose physical capacities decrease. The quantification of this movement was proposed using a magneto-inertial measurement unit fixed on the chest. This sensor is small and inexpensive, adapted for ambulatory measurements.First, it was necessary to validate the measurements of the kinematic and the kinetic energy using the inertial unit during the sit-to-stand. This validation was realized on a panel of young and healthy subjects compared to a V icon motion captur using cameras.The second objective was to compare different populations through the quantification of the sit-to-stand. In addition of the healthy young subjects, a group of healthy elderly subjects was included in to study the age effect. A group of frail elderly subjects was also included to investigate the effect of frailty. We proposed the implementation of two composite scores based on the measured parameters. The first is an aging score and the second is a frailty score. Each score was constructed using a principal component analysis. The performance of each score is better than that of any parameter considered independently

Texto completo da fonteIntroduction: Parkinson's disease (PD) is a chronic neurodegenerative disorder that predominantly impairs motor function and affects millions of people worldwide. Rigidity is one of the main symptoms of PD and is present in around 89% of patients. This rigidity makes it difficult to move limbs, affecting the quality of life of these people. The assessment of rigidity is of great importance in clinical practice to monitor the rehabilitation process. Traditional methods for assessing rigidity, such as the Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) have limitations, leading to the exploration of novel approaches. However, there are still no standardised quantitative measures for this assessment. Therefore, there is great interest in implementing new methods that can adequately quantify this disorder. Methods that use Electromyography (EMG) and joint amplitude sensors are very promising. Objective: Therefore, the general objective of this research is to propose and evaluate a method for the quantitative assessment of wrist rigidity in patients with PD, using inertial sensors and EMG. Methods: Initially, a literature review was conducted to identify the most suitable and consistent sensors for this purpose. Based on this review, an experimental protocol was developed that incorporates a variety of movements, including active, slow passive, and fast passive stretches, to capture different aspects of rigidity. The protocol also includes participant interaction with the RehaBEElitation, a serious game that aims to provide an engaging and accessible approach to assessing rigidity. For the study, 15 people with PD were evaluated, in the ON and OFF states of the medication and 15 healthy people, matched in sex and age. Results and Discussion: The main findings highlight speed as a crucial determinant in the manifestation of rigidity in individuals with PD. It was observed that fast passive movements were the most effective in causing and highlighting rigidity, while slow passive movements showed less significant results. Furthermore, phase 4 of RehaBEElitation emerged as a highlight, proving to be crucial for identifying and evaluating rigidity. Features estimated from signals of accelerometers and gyroscopes were particularly notable, demonstrating strong correlation with MDS-UPDRS assessment, and offering valuable insights into the movement dynamics. On the other hand, EMG proved to be more effective, in detecting rigidity, when movements were ordered, highlighting the importance of muscular coordination in assessing rigidity when using this method. These findings highlight the complexity of rigidity in PD and the need for multifaceted and sensitive approaches to its assessment and understanding. Conclusion: In conclusion, this study successfully developed and implemented a new method to quantify wrist rigidity in individuals with PD. The results demonstrated strong correlations between sensor data and clinical assessments, indicating the effectiveness of the developed method in accurately quantifying wrist rigidity in different disease states. These findings underscore the potential of the proposed approach to improve the clinical management of PD, offering valuable insights into motor symptoms and paving the way for personalized interventions tailored to address rigidity and improve quality of life for PD patients

Texto completo da fonteAbstract : Introduction: Children with developmental coordination disorder (DCD) have difficulties learning motor tasks, especially for the ones requiring motor coordination. Numerous neuroimaging studies demonstrated a decrease in neuronal activity in the cerebellum, what might be responsible for motor learning difficulties in children with DCD. Increasing neuronal activity in the cerebellum might be an interesting avenue to improve learning and motor coordination. Anodal transcranial direct current stimulation (a-tDCS) has been shown to increase neuronal activity of the stimulated region, and to improve motor learning in healthy adults or patients with neurological disorders. To our knowledge, no study has assessed the tDCS effectiveness on motor learning for children with DCD. Objective: The present study evaluates the effect of cerebellar a-tDCS application on the motor learning and upper limb coordination of children with DCD. Methods: A pre-post experimental study with an equivalent control group was performed. Nineteen children aged 10-17 years were randomized in one of the two groups (active or placebo stimulation). During three sessions, participants received an anodal stimulation (2mA or placebo) on the cerebellum. The stimulation was carried out for 20 minutes while children simultaneously performed the Serial Reaction Time Task (SRTT), used to document motor learning through response speed and error rate. The motor coordination of the upper limb was evaluated by the finger-nose test (FNT) before and after each tDCS session. Results: The cerebellar a-tDCS could not significantly improve motor learning but a clinical reduction on error rate for the active group versus placebo group (p=0.072). The tDCS application did not show significantly improvement on speed and motor coordination between two groups. Conclusion: The a-tDCS could potentially improve motor learning by decreasing the error rate of children with DCD. However, more researches are needed to explore if the tDCS could be an interesting therapeutic tool to improve the effectiveness of motor learning interventions for children with DCD.

Texto completo da fonteThe emergence of Musculo-Squelettal Disorders (MSD) in the industry is a real blight, having major socioeconomic consequences in France. In order to reduce work painfulness and MSD risks, some industries are committing to modifying workstations by assisting operators with robotic devices. Following this MSD prevention policy, PSA Peugeot Citroen aims to use cobots or exoskeletons as assistive devices to improve workers conditions. However, implementing this type of robot in factories requires quantifying their ergonomic benefit. In this context, the objective of this thesis is to develop a method to assess collaborative robot that are intended to be used in PSA Peugeot Citroen factories. In this framework, the right mono-arm ABLE exoskeleton, designed by the CEA-LIST has been used. With a biomechanical analysis of an industrial manipulation task, we have been able to assess the benefit of the exoskeleton in terms of physical load reduction. We also proposed in this work to assess neuromuscular mechanisms underlying the industrial task performed in interaction with the exoskeleton. On the basis of the human motor control theory and using an inverse optimisation method, objectives functions such as jerk, joint torque or energy that characterize the human manipulation task in terms of efforts, kinematics and execution time, have been identified. This improved understanding of human upper limb movements then allowed reviewing the exoskeleton design in order to propose an optimal command strategy adapted to the execution of industrial tasks
