Biofeedback Equipment, 5 Things You Need to Know
Are you thinking of getting biofeedback equipment? Here are 5 things you need to know.
- What is it measuring? Biofeedback instruments may measure different things. All biofeedback instruments are not the same. There are different modalities that can be measured including surface EMG for muscle tension, Skin Temperature, Skin Conductance, Respiration, Heart Rate, Heart Rate Variability, EEG, and CO2 (Capnometry). Some biofeedback equipment measures only one of these modalities. Others may measure up to 10 separate channels at the same time.
- Do I have a reliable signal? The feedback that the instrument provides is only as good as the quality of the signal. If the signal is not accurate it is not a good representation of the changes happening in the body. Some biofeedback equipment makes it easy to see the quality of the signal. Other instruments may hide the actual signal and only show you a game or give you sound that is supposed to be reacting to the signal.
