Clinicians frequently assess and intervene on postural alignment. However, research demonstrating the effects of exercise interventions in moving postural alignment toward an evidence-based standard is lacking. Part of the difficulty in establishing such evidence has been a lack of theory-motivated conceptions of what "good" posture is. In other words, the prevailing understanding of postural alignment is based on the negation of what has been observed to associate with bad outcomes. This study will build upon preliminary findings from our laboratory that define good postural alignment on theoretical grounds. The investigators will measure motion capture and muscle activation patterns during simple postural alignment tasks before and after 1) a corrective exercise intervention, or 2) a control intervention based designed to inhibit superficial muscle tension. The corrective exercise intervention is designed to counteract the natural patterns in which the human skeleton tends to collapse from a standing position under the influence of gravity. The control intervention consists of passive, partner-assisted stretching. Regardless of initial assignment, all participants will crossover (i.e. switch interventions) and repeat the study procedures after a 1-week washout period. Behavioral indicators of movement and nervous system coordination will be used to quantify alignment before and after exercise, as well as the consistency of those alignment patterns with theoretically-defined standards. The knowledge gained from this study will contribute to evidence-based definitions of healthy postural alignment and help identify effective interventions by which clinicians can promote good posture.
The facial palsy is a frequent disease with a lot of etiologies. It has variable severities with sometimes heavy functional repercussions and different recovery potentials. The proposed treatments are based on surgery, physiotherapy and botulinum toxin injections. However, when recovery is incomplete, acceptance is more difficult, with an impacted quality of life. Thanks to Motion Capture and Electromyography, a quantification of the facial mimicry is now possible with a great precision. In addition with the quantification of the facial mimicry, eye-tracking, wich is widely used in the marketing field, but it also finds medical applications including head and neck lesions and facial palsy in particular, will be used to evaluate the visio of the patients on their pathology in function of the movement quantification measured with MoCap and Electromyography. The aim of this research is to measure in a combined way the action potentials by sEMG and the amplitudes of displacement of the markers in motion capture, for movements determined in a population of patients presenting a facial pathology, in order to compare them with reference values obtained in healthy subjects. In a second step, the aim will be to study if there is a link between the way the patient looks at his pathology and the results of his management (treatment, rehabilitation) which will be quantitatively evaluated thanks to MoCap and sEMG.
Evaluation of the efficacy of the occlusal appliance with active cannabidiol (CBD) molecules in TMD patients
Disc herniation is a common cause of low back pain and leg pain. Electromyography is the only test that can objectively examine nerve damage caused by a lumbar disc herniation. This study aimed to compare the MRI findings of disc herniation and the aspects of electromyography.
The objective of this study is to assess the impact of different positions of the glenohumeral joint on the maximum muscle contraction of different shoulder muscles. The muscles do not contract with the same intensity depending on the position of the arm in relation to the trunk. With the determination of this optimal position to activate the shoulder muscles as much as possible, we will be able to strengthen the patients during their revalidation.
