Numerous studies using sEMG to recorded diaphragm activity was performed in a various methodology. For example, in one of the study to record the activity of the diaphragm, the electrodes were placed in the seventh or eighth intercostal space on the right side of the body at the midclavicular line. In other studies, the diaphragm electrodes were placed in the lowest intercostal spaces on the right side of the body, at the mid-clavicular line. Which method is correct, more sensitive and more precise? Are there any possible other methods of electrodes placements in diaphragm sEMG?
We use one of the technique proposed by Shin J OH. ; electrodes in the 7-8th intercostal space; other methods can also be used acc to experience.
Dear colleague,
I think that you can not make an electromyographic recording of the diaphragm with surface electrodes, because before you got this muscle, you got the intercostal muscles, which interfere the electrical signal of the first one. To achieve record of the electrical activity of diaphragm muscle you must use needle electromyography.
Dr. Nor
I agree with the method described in Sin J Oh textbook.
But you can use small subcutaneous monopolar needles instead of adesive electrodes to reduce impedence . The needle recording with emg needle ditecly fom diaphragm mey be armful
