Filter by:The aim of this study is to investigate the possible effects that a motor limitation at the peripheral level might have on the ability to visually discriminate others' actions. Previous literature has shown that specific motor skills (motor expertise) facilitate the visual discrimination of domain-specific actions, and that these motor experts' superior abilities might be mediated by areas not only responsible for the visual recognition of movements (as it happens in non-expert subjects) but also involved in motor planning. Similarly, impairment in the motor system due to neurological damage modulates not only the ability to perform movements but also the ability to discriminate and predict the temporal course of observed actions. Based on these findings, it has been hypothesized that the motor representations of gait, despite being a hyper-learned motor pattern, might be subjected to modification as a result of an impairment of walking caused by a peripheral functional limitation in the lower limbs as the one characterizing orthopaedic patients who underwent a surgical operation for total knee arthroprosthesis. In this protocol, patients are thus required to perform visual discrimination tasks based on the observation of movements performed with either the upper or lower limbs, and their performance is expected to correlated with their functional impairments in movement execution. These results would indicate that the (in)ability to perform a movement might have an impact on its representation at the central level and on internal motion simulation capabilities, which also influence the ability to visual discriminate others' actions through action-perception transfer: this would suggest that rehabilitation in orthopaedic patients should take into account (and restore) such a central impairment in motor representations.
The aim of the study is to investigate the capacity of post-stroke individual (study group) to modulate their EMG muscle activation pattern (MAP) compared to healthy individuals (control group), and to correlate these capacities with their motor impairments. Twenty post-stroke individuals and 12 healthy individuals will participate in this study. each participant will carry out hand-reaching movements in multiple directions, monitored by an EMG device. The modulation of the EMG signal will be compared between groups in terms of EMG-MAP and in terms of muscle-synergies. Additionally the MAPs and synergies of the study group will be correlated with their Fugl-Meyer (FM) assessment scores. Analysis of the muscle synergies underlying the EMG signal will be carried out by the Non-negative Matrix Factorization (NMF) algorithm.
The combination of motor disabilities, chronic pain, cognitive disabilities limiting the possibilities of communications and repeated potentially painful rehabilitation, exposes patients with motor disabilities to a high risk of induced pain in the specialized establishments. Induced pain is difficult to detect and is therefore little assessed and treated. Currently, little is known about the prevalence and conditions of occurrence of such induced pain as the clinical characteristics of patients (children, adults, severity of disability), the types of care and the nature of the institutional admission (medical or medico-social). Secondary objectives are to identify risk factors related to the induced pain and patient characteristics, as well as to create an easy-to-use weekly continuous pain assessment tool in a routine clinical set-up. All daily life procedures or treatment carried out in children and adults with motor disability are collected for 5 days and 1 night. Collected data are clinical and demographic characteristics of patients, the intensity of the pain assessed by the care professional (FLACC-r) or the patient himself (VAS). Clinically, the uncomfortable and painful procedures and risk factors for pain identified by this study will help the development of targeted preventive measures within institutions. Meanwhile, the study should sensitize Breton teams involved with regards to the induced pain, leading them to observe the behavior of patients, to admit any pain related to an act of daily life, and to ask for the medical profession to anticipate the painful experience.
