Filter by:Adolescent Idiopathic Scoliosis (AIS) is a complex three-dimensional spinal deformity with onset in adolescents between the ages of 10 and 18 years, characterized by coronal curvature, sagittal imbalance and horizontal rotation of the spine. The incidence of AIS is 1-4% globally, with more females than males, and it is a common, frequent and difficult-to-treat disease that seriously jeopardizes the physical and mental health of adolescents. Previous studies have found significant changes in the morphologic structure and physiologic characteristics of the paraspinal muscles in patients with AIS, including muscle fiber distribution, muscle contraction and relaxation capacity, the convex side of the AIS curve exhibits a higher level of electromyographic activity, and asymmetric changes in the paraspinal muscles are highly correlated with progression of scoliosis. The current single-electrode sEMG technique extracts limited muscle activity signals and is susceptible to interference from random noise. Compared with the single-electrode sEMG technique, HD-sEMG can provide rich spatiotemporal information on paraspinal muscle activity, so it is necessary to use a wide and closely spaced electrode array for signal acquisition to obtain more accurate and detailed characteristics of paraspinal muscle activity. In summary, this study used high-density surface electromyography to collect muscle parameters of the paraspinal muscles on the concave and convex sides of AIS patients and compared them with those of healthy people to comprehensively summarize the characteristics of their paraspinal muscles, so as to provide scientific basis for the subsequent development of precise treatment plans and improvement of clinical efficacy.
The goal of this observational study is to analyze the differences in muscle activation of six muscles of the lower leg (soleus, gastrocnemius medialis, gastrocnemius lateralis, tibialis anterior, peroneus longus, peroneus brevis) in seven possible configurations of a specific instability device, the Blackboard (BB), as well as on the floor, among healthy active subjects. The main questions it aims to answer are: 1. Which configuration of the BB produces the highest activation for each studied muscle? 2. Which muscle is the most activated in each configuration of the BB? 3. What is the muscle activation pattern obtained in each configuration of the BB? A single group of participants will be analyzed. Both the studied leg and the order of configurations of the instability device and ground condition will be randomly assigned. Participants will first undergo a 2-minute continuous walking warm-up, followed by a performance of a maximum voluntary isometric contraction (MVIC) for each muscle, during which the maximum activation produced will be recorded. Each participant will be allowed a 30-second familiarization period on the most unstable configuration of the BB. Three repetitions of 20 seconds will be recorded on both the ground and each configuration, with a 30-second rest between repetitions. The central 10 seconds of each trial will be used for subsequent analysis. The mean of the three repetitions for each muscle will be calculated and subsequently processed and normalized by the maximum activation value during the MIVC. Finally, a statistical analysis of the differences in muscle activation in each configuration will be conducted with the intention of addressing the mentioned questions.
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 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.
The investigators aimed to divide the healthy individuals aged between 18-45 years, included in our study, into three groups as bilateral, unilateral-right and unilateral-left Auricular Vagus Nerve Stimulation (VNS). The investigators planned to examine the effects of vagal nerve stimulation applied to each group with superficial EMG and EEG measurements before and after. Auricular vagus nerve stimulation has effects on cerebral activity. Therefore, this effect will be evaluated with EEG. In addition, whether there is a secondary peripheral effect will be examined by EMG method. Changes to be detected in EEG and EMG in healthy individuals may give an idea about the use of auricular vagus nerve stimulation in patients. In this study, healthy individuals between the ages of 18-45, who do not have any chronic diseases and who do not have to use any medication regularly will be included in all three groups. Due to the superficial EMG measurement method the investigators used, those who have orthopedic problems in the upper extremity (shoulder, elbow, wrist and fingers) or have a history of surgical operation in the upper extremity, however, any systemic disease such as diabetes, gout, chronic kidney failure, rheumatoid arthritis, thyroid diseases individuals will be excluded from the study in all three groups.
A cross-sectional descriptive study, in which the surface electromyographic activity of five shoulder muscles was compared in two populations: older adults and adults. The evaluation of the electromyographic data offers a suitable foundation to understand aging process. This supports that surface electromyography provide information about the aged shoulder muscles. Loss of functionality is suffered by a high percentage of older adults, which greatly limits their physical activity. In this sense, this paper presents findings that might be related with possible therapeutic approaches in subsequent studies.
Purpose: Assessing nociception and sedation in mechanically ventilated patients in the ICU is challenging, with few reliable methods available for continuous monitoring. Measurable cardiovascular and neurophysiological variables, such as blood pressure, heart rate, frontal EEG, and frontal EMG, might provide a medium for sedation and nociception monitoring. The hypothesis of this explorative study is that the aforementioned variables correlate with the level of sedation, as described by the Richmond Agitation-Sedation score (RASS). Methods: Thirty adult postoperative ICU patients on mechanical ventilation and receiving intravenous sedation, excluding patients with primary neurological disorders, head injury, or need for continuous neuromuscular blockage. Continuous measurements of bispectral index (BIS), EMG power (EMG), EMG-derived Responsiveness Index (RI), averaged blood pressure variability (ARV), and Surgical Pleth Index (SPI) were tested against repeated RASS measurements, and separately against responsiveness to painful stimuli at varying RASS levels.
Evaluation of myorelaxant effect of cannabis cream.compared to placebo cream in topical skin application in patients with TMD
The main objective of this research is to demonstrate that the use of insoles of different hardness in motorcycle riders may cause variations in the electromyographic activity of the lower limb muscles during the race. This study is a cross-over quasi-experimental study. Nine motorcycle riders were recruited. Electromyographic activity of the lower limb muscles is recorded under different insole types.
Chronic pelvic pain (CPP) is a common presenting complaint affecting approximately 15-40 % of women aged 18-50 in western countries and 5-43% of women in most developing countries. It is debilitating and has a large socio- economic impact, with a 45%reduction in work productivity, and a 15% increase in absence from work in women with the condition. Botulinum neurotoxin type A (BoNTA) has been suggested to improve pain in muscle spasm, its role in CPP secondary to pelvic floor spasm has gained increasing interest. However, clinicians do not have a diagnosis tool to evaluate the CPP and the BoNTA treatment results. Design and develop an efficient and simple tool for the diagnosis and detection of pelvic floor muscle (PFM) dysfunction based on superficial electromyography (EMG) and perform 25 EMG registrations sessions in healthy patients and 25 EMG sessions in patients diagnoses with PFM that will be treated with BoNTA to and study the EMG signal before and after BoNTA administration.
