This work describes a hybrid adaptive filtering technique, designed to optimize the removal of the electrocardiogram (ECG) from surface electromyography (sEMG) recordings. Using the adaptive noise cancellation technique (ANC), we minimize the error gradient based on combined Time-Frequency filtering enhancements. The validation on artificially prepared signals with a real data basis shows bette...

Physical rehabilitation typically conjures up images of an adult in physical therapy to recover from an accident or injury. Children are also the unfortunate victims of strokes, head injuries, and developmental disorders. In this case study, a child with a rare genetic disorder is helped to learn to stand using a modification of surface electromyography, quantitative surface electromyography (Q...

Background: recent studies have used ultrasonography with the purpose of measuring muscle cuts. Aim: to characterize the motor control and the morphology of the masseter muscle in normal individuals, verifying the compatibility between surface electromyography and ultrasonography. Method: five adult individuals, with no alterations of the stomatognathic system. The adopted assessment procedures...

Needle and surface electromyography are 2 distinct modalities. They are both electro-physiological techniques aimed at the investigation of neuromuscular dysfunction. The clinical utilization of each technique is insuffi ciently known to the nonspecialist or to the typical patient. The present article aims at presenting a succint description of each modality and the differences between the two ...

[Purpose] This study was to compare the shoulder and trunk muscle activity according to the various resistance condition during knee push-up-plus. [Subjects and Methods] Twenty healthy adults participated in this study (9 males and 11 females). The subjects performed dominant-leg-extended knee push-up-plus apply to resistance in the direction of abduction, adduction, extension and the flexion. ...
