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 [...]

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) [...]

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 [...]
