Electromyography (EMG) is the analytical study of electrical activity produced by skeletal muscles. EMG is an example of modern human computer interaction which can be used in the field of medicines and engineering. Through this paper we are going to discuss about different types of EMG-Surface EMG(SEMG)/surface scanning EMG and intramuscular/ indwelling (needle and fine-wire) EMG, the electric...

The electrocardiography (ECG) artifact in surface electromyography (sEMG) is a major source of noise influencing the analyses. Moreover, in many cases the sEMG signal is the only available signal, making this removal more complicated. We compare the performance of two recently described single channel blind source separation methods with the commonly used template subtraction method on both sim...

Currently, trans-radial amputees can only perform a few simple movements with prosthetic hands. This is mainly due to low control capabilities and the long training time that is required to learn controlling them with surface electromyography (sEMG). This is in contrast with recent advances in mechatronics, thanks to which mechanical hands have multiple degrees of freedom and in some cases forc...

OBJECTIVE To assess the effect of core strengthening exercises on Cobb angle and muscle activity in male college students with functional scoliosis. METHODS Static and dynamic back muscle activity were evaluated via surface electromyography (sEMG). A core exercise protocol comprising 18 exercises was performed three times/week for 10 weeks. Patients were randomly allocated to either a home- o...

The purpose of the present study was to evaluate the effects of a trunk exercise program on the gait and muscle activity in stroke patients. The participants of this pilot study included six hemiplegic stroke patients. The outcomes were surface electromyography (sEMG) and spatiotemporal gait parameters. In analysis of sEMG, no statistically difference was found between preand post-training of M...

A recent study has proved that unilateral deep brain stimulation (DBS) of the subthalamic nucleus has bilateral effects. However, it is still unclear whether unilateral ventral intermediate thalamic nucleus (Vim) DBS exerts exclusively contralateral or bilateral effects on tremor. Previous studies demonstrated a clinically irrelevant improvement on the nontarget side after thalamic stimulator i...

[Purpose] The purpose of this study was to examine the immediate effects of strength training and neuromuscular joint facilitation (NJF) distal resistance training on muscle strength and proprioception. [Subjects] The subjects were 15 young healthy people (29.3±4.1 y, 166.8±7.1 cm, 62.4 ± 11.6 ky). [Methods] Two isometric contraction techniques were applied on the elbow joint: elbow joint flexi...

INTRODUCTION Proper ergonomic positioning in the workplace is crucial in preventing musculoskeletal disorders (MSD) resulting from prolonged muscular fatigue. Specifically in microlaryngoscopy, surgeons often disregard proper ergonomic positioning in favor of dexterity and range of motion during surgery, leading to increased muscle fatigue through neck strain and compressive forces [1]. Similar...

OBJECTIVES To answer the clinical research question: in patients with myofascial pain, are there any differences in the surface electromyography (sEMG) activity of muscles of the painful and nonpainful sides that can be detected by commercially available devices? METHODS The study sample (N = 39; 64% F, mean age 35.7 ± 15 years) consisted of patients seeking for temporomandibular disorders Te...

The classification of imbalanced datasets, especially in medicine, is a major problem data mining. Such evident analyzing normal and abnormal subjects about knee from collected during walking. In this work, surface electromyography (sEMG) were walking the lower limb 22 individuals (11 with 11 without abnormality). Subjects abnormality take longer to complete task than healthy subjects. Therefor...
