For several decades, studies throughout the motor control literature have claimed synchronization of motor unit firings result from common presynaptic branches, or “common inputs” shared by the motoneurons. However, the […]
Over the last half-century, numerous attempts have been made to decompose surface EMG signals into individual motor unit firings. Unfortunately, identifying these firings amidst ambient noise and the activity of […]
Researchers at the University of Porto, Portugal are investigating the untapped potential of video “exergames” as tools for exercise and sports training. With the ever-increasing popularity of video games, strong […]
Only a few studies have investigated the changes in the spectral characteristics of the surface electromyographic (sEMG) signal that are induced by neuromuscular modifications following a stroke. Also, little has […]
The root-mean-square (RMS) envelope of the EMG signal is calculated using a moving window, with each window of data calculated according to the following equation: ,where S equals the window length […]
Background Stroke rehabilitation is a challenging, lengthy process that patients must undergo to regain motor function. Recovery effectiveness and efficiency can be increased by further understanding the neuromuscular system during […]
Electromyogram (EMG) signals have proven to be quite effective as tools for researching muscular fatigue. These EMG signals are capable of providing electrical data for an individual muscle, which allows […]
MVC normalization is a commonly used amplitude analysis technique on EMG signals. This post-processing method utilizes a maximum root mean square (RMS) value from a recording to normalize subsequent EMG […]
