TLDR
The analysis established the relationship between the attenuation rates of the movement artifact and the sEMG signal as a function of the filter band pass, and a Butterworth filter with a corner frequency of 20 Hz and a slope of 12 dB/oct is recommended for general use.About:

Jian Wu,Lu Sun,Roozbeh Jafari +2 more
TL;DR: A wearable system for recognizing ASL in real time is proposed, fusing information from an inertial sensor and sEMG sensors, and an information gain-based feature selection scheme is used to select the best subset of features from a broad range of well-established features.

Roller-massager application to the hamstrings increases sit-and-reach range of motion within five to ten seconds without performance impairments.
TL;DR: The use of the roller-massager had no significant effect on muscle strength, and can provide statistically significant increases in ROM, particularly when used for a longer duration.

Inter-electrode spacing of surface EMG sensors: reduction of crosstalk contamination during voluntary contractions.
TL;DR: Crosstalk contamination and inter-electrode spacing should be a serious concern in gait studies when the sEMG signal is collected with single differential sensors because it can distort the target muscle signal and mislead the interpretation of its activation timing and force magnitude.

Investigation into the origin of the noise of surface electrodes.
TL;DR: It was found that the noise mainly originates in the electrolyte-skin interface and that it is highly dependent on the electrode gel used and the skin properties of the test subject, as well as the contribution of EMG signals to the total noise level.
