processEMG_ACC

Scripts for signal processing electromyography (EMG) or acceleration sensor data (ACC)

Pre-requisites:

• Input data in .txt/.dat or .acq (Biopac) files
• If used for convolution or block design analysis, signal must be synchronized with start block (signal before experiment start must be removed)

Basic Features:

• Calculates RMS of raw EMG signal or acceleration sensor data
• Extraction of mean RMS signal per block (user specifies blocks of data with regular length)
• Output to data sheets for statistical analysis
• Output plots of signal

Special Purpose Features:

• Convolution with hemodynamic response functions (HRF) to use signals as regressor in GLM analysis of fMRI data
• Grip detection for gripping hand movements measured with acceleration sensor
