Filter by:Carpal tunnel syndrome is the most common entrapment neuropathy and is frequently encountered in clinical practice. Although there is no standard protocol for its treatment, conservative treatment methods are preferred. In our study, we aimed to clinically compare the efficacy of high and low intensity laser treatments in patients with carpal tunnel syndrome. By using methods such as electromyography and ultrasound, we aimed to provide a more objective evaluation
This study will use electromyography to evaluate activation patterns of the vastus medialis and vastus lateralis muscles during the McMurray's knee examination test in different knee positions.
The purpose of this small-scale exploratory study is to bridge the knowledge gap between the bench testing and the design of potential future confirmative studies. Identifying and evaluating MicroEMG measurement parameters in this exploratory manner is a necessary step to evaluate its usability and design, and determine whether the microEMG system may be suitable for in-house use after further confirmative testing.
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.
Noise stimulation had an immediate effect on improving balance control. The present study aimed to clarify the immediate neuromuscular adaptation induced by noise stimulation and find the correlation between neuromuscular adaptation and functional performance.
The objective of this study is to investigate whether electromyography of the diaphragm during sleep in asthmatic children can be used to objectively monitor asthma control.
Closed kinetic chain (CKC) exercises are exercises in which body weight is carried on the distal segment. It is considered advantageous and reliable in many respects compared to open kinetic chain exercises (OKC). For the restoration of functional stability in shoulder rehabilitation, it is recommended to use CKC exercises that carry body weight from the early period. Plank exercise, which is frequently used to strengthen the core area in rehabilitation programs, is performed by transferring weight on the upper extremity. For this reason, it is thought that this exercise will provide an isometric load on the shoulder and scapula muscles. In many previous studies, it has been observed that scapular muscle activations also change with the changes in stability (support surface properties, etc.) in plank exercises and variations in a way that provides a more stable exercise environment. However, as the difficulty level of the used moving floor increased (using softer or unstable surfaces), it was seen that the increase in muscle activation levels was more in favor of the upper trapezius muscle (UT). In a study, it was observed that the UT / Middle Trapeze (MT), UT / Lower Trapezius (LT), UT / Serratus Anterior (SA) ratios were lower in the 3-point supported plank exercise performed on one hand. For this reason, it is thought that while the difficulty level of plank variations is increased in shoulder rehabilitation, body position changes will be more effective in maintaining optimal scapular muscle activation rates instead of using a moving floor. Based on this information, investigating the muscular activation levels for the scapular and shoulder girdle muscles during different variations of the plank exercise in terms of load levels in the targeted muscles will provide valuable information for the management of shoulder exercise programs and post-operative rehabilitation. It was planned to include 21 healthy physically active individuals between the ages of 18-45 in the study. Muscle activation levels during maximum voluntary isometric contraction (MVIC) of each muscle will be recorded to normalize muscle activation levels during plank variations. Muscle activation levels will be evaluated with a surface electromyography device (Noraxon, Myomotion, USA).
This research is being performed to characterize the rowing stroke in active and inactive individuals who use a manual wheelchair. The investigators will be looking at muscle activity of four shoulder muscles (upper trapezius, lower trapezius, serratus anterior, and posterior deltoid) and motion of the arms, shoulder blade, and trunk during rowing. This will be done for three rowing conditions (1: adapted rowing ergometer, 2: rowing ergometer from a chair, 3: standard seated row exercise using an elastic band [TheraBand]). The investigators are also looking at shoulder strength, range of motion, quality of life, and community participation.
This is an observational analytical study of prevalent cases and controls.
