This BIOPAC Basic Script computes statistical measures of heart rate variability in user-specified time intervals. The statistics computed are described in Application Note 129. Specifically they are the RMSSD, SDSD, and pNN50. Output from the script is a spreadsheet containing these statistics and the time intervals over which they are computed.
Script download includes script file and a modified version of the ECG Lead II sample data file.
The fEMG Electromyography Smart Amplifier is designed specifically for recording facial EMG signals and electrical activity from other small muscle groups. Use with AcqKnowledge™ software to analyze facial expressions and startle paradigms. BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level […]
Recent Exercise Physiology studies feature BIOPAC’s MP Research series of Data Collection recorders and AcqKnowledge software. These studies promote healthy living and observe muscle response to normal physiological motions during exercise! Trampoline Workouts for Seniors? As we get older, our joints ache and muscles stiffen—but scientists are finding new ways to not only help us […]
