In what situation might in be better to position the electrodes on the upper arm and the thighs rather than lower on the arms and legs?

Positioning electrodes on the upper arm and thighs may be preferable in situations where larger muscle groups are being targeted, such as during strength training or rehabilitation exercises. This placement can enhance the detection of electrical activity in these muscles, leading to more accurate readings. Additionally, it may help reduce interference from motion artifacts that can occur when electrodes are placed lower on the limbs. Finally, this positioning can also facilitate comfort and ease of movement during certain activities.
