| Popis: | Dual recordings of single motor unit (SMU) biopotentials were made utilizing abraded skin surface and intramuscular (IM) bipolar electrode placements. Time relationships and waveform isomorphy between the recorded potentials suggest that, within limits, surface electrode recording is a useful technique for registering certain muscle action potentials when intramuscular placements are not desirable. Pen records of good resolution were obtained, to supplement oscilloscope photographs, when the physiological signal was initially recorded on magnetic tape at high speed and then played back at low speed through a standard electroencephalograph-electromyograph oscillograph. |
