How to use EMGscripts for Fatigue Analysis

November 4th, 2014|Categories: Blogs, Support|

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 for the use of a spectral fatigue index to describe [...]

EMG monitored Wii-based Movement Therapy for Stroke Rehabilitation

November 4th, 2014|Categories: Blogs, Research Videos|

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 post-stroke recovery. This involves monitoring electromyographic (EMG) signals during rehabilitation, [...]

Amplitude Analysis: Root-mean-square EMG Envelope

November 4th, 2014|Categories: Blogs, Support|

Overview: 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 (points) and f(s) equals the data within the [...]

Amplitude Analysis: Normalization of EMG to Maximum Voluntary Contraction (MVC)

November 3rd, 2014|Categories: Blogs, Support|

Overview: 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 data series. The output is displayed as a percentage [...]
