System Overview Test Modality Descriptions Introduction Electromyography (EMG) This section provides an overview of the test categories performed by VIASYS neurodiagnostic instruments. Electromyography is the recording and analysis of the insertional, spontaneous an involuntary electrical activity generated by single or group muscle action. The recorded waveforms are called motor unit action potentials (MUAPs).
Neurodiagnostic Instruments Service Manual Evoked Potentials (EP) An evoked potential (EP) is an electrical response of the nervous system to a sensory stimulation. EP’s are used to check the condition of nerve pathways. A healthy nervous system uses electrical energy to carry messages smoothly along nerve cells to the brain. An EP test will measure the brains’s electrical response to the signals sent by the nerves.
System Overview Visual Evoked Potential Principles of Signal Averaging A Visual Evoked Potential (VEP) is used to check the neuro pathways from the eyes to the occipital area in the brain. Visual evoked potentials are used to diagnose visual losses due to optic nerve damage, especially from multiple sclerosis. They are also useful to diagnose “hysterical blindness,” in which loss of vision is not due to any nerve damage.
Neurodiagnostic Instruments Service Manual This noise appears as a spike in the waveform with a frequency the same as the monitor sync frequency. Environmental Noise The sensitive amplifiers can pick up all kinds of electromagnetic radiation through the electrode leads or power lines.
System Overview Neurodiagnostic Instrument - Generic Block Diagram Electrical Stimulator Pattern Reversal Visual Stimulator STIM Stimulus Pulse Generator Auditory Stimulator Electrodes to Patient Input Select Switches CAL Amp Signal Conditioning LFF, HFF, NCH, SNS Amp Signal Conditioning LFF, HFF, NCH, SNS SIGNAL A/B SELECT ADJUST MARK Printer Analog to Digital Converter (Digitizer) Generic NCS/EMG/EP System The diagram above represents a generic NCS/EMG/EP system.
Neurodiagnostic Instruments Service Manual Signal Conditioning Stimulators The energy of each type of evoked response lies within a well-defined band of frequencies. The signal conditioning block reduces frequencies outside of this window of interest in an effort to “clean up” the waveform before averaging takes place. The signal condition block also adjusts the signal amplitude for optimum results.
System Overview Auditory Stimulator Analog-to-Digital Converter The Auditory Stimulator provides a click or a tone stimulus. The system user controls the stimulus rate, duration, intensity level and polarity. The three types of click polarity are: The Analog-to-Digital Converter changes the incoming analog signal to a series of digital values that represent the data. This device runs continuously during data acquisition, sending a constant stream of digital values to system memory.

Troubleshooting Symptoms and Solutions This section describes some specific troubleshooting techniques to try for several symptom categories. Noise/Artifact Problems Noisy waveforms are the most common type of problem with neurodiagnostic systems, as the amplifiers are very sensitive, and able to pick up minute amounts of noise from a variety of sources. Evoked potential tests and sensory nerve conduction tests are most affected by noise problems.
Neurodiagnostic Instruments Service Manual Troubleshooting Noise: Environmental Checklist Items to check Detail 12. If in an office environment, are there any appliances in the room with the system? Yes: ___ No: ___ Toasters, microwaves, computers, lamps, coffee machines, etc. 13. Unplug any non-critical care equipment in the O.R. Heat lamps, microscope, electric bed, warmers, etc. 14. Move the system to a different room away from the existing location.
Troubleshooting Troubleshooting Noise: Equipment Checklist Items to check Detail 1. Check the live signal (View Input mode). If noise is locked in place on the waveform or seemingly triggered from one place on the waveform screen, change the stimulator rate to an odd number to avoid time-locking the sweep to 50/60Hz noise. Adjust the stim rate until the signal rolls on the screen. This will be averaged out over time. Use an odd number, such as 10.3 or 11.1 stimuli/sec. for an ABR; 4.7 or 5.1 for a VEP.
Neurodiagnostic Instruments Service Manual Other Data-Related Problems No patient data displayed After you have verified that the system power is OFF, disconnect and reconnect the cabling from the amplifier to the console base. Disconnect and reconnect all cabling to the console base and the processor. Run the USB/FireWire Diagnostics to verify the amplifier/stimulator modules are recognized and functioning correctly.
Troubleshooting Filter Tests . The Endeavor CR and Viking amplifier systems use a combination of digital (software) and hardware filters. Normally, the USB/FireWire diagnostics will detect amplifier problems. If, however, you experience a wave shape-related problem that is ambiguous in nature, you may want to verify that all hardware filters are working properly. LFF=0.
Neurodiagnostic Instruments Service Manual Computer Problems Slow operation (VikingQuest) Base Unit blows fuses If you replace printers and install a new printer driver on the system, the waveform data displayed on the screen may become very slow. The QMUP test displays a slow-moving flat dashed data line. To resolve this issue, you have to uninstall the printer driver, reinstall the printer driver, then reload the Master Software, in that order.
Troubleshooting Printer Problems Common printer problems include: • Your printer generates nonsense printouts • Your printer will not print a screen copy. • Your printer is continuously feeding paper. These conditions usually indicate that the wrong printer type is selected in the Printer Setup of the Master Settings. 5. Close the options window and check the printer spool for any screen copies.
Neurodiagnostic Instruments Service Manual Electrical Stimulator Problems Testing Electrical Stimulator Specifications Is the VikingQuest or VikingSelect control panel Stimulator LED blinking to indicate a STIM ON condition? If so, is the Stim Probe connected to the probe jack? If you suspect an electrical stimulator is not performing to specification, you may check the stimulator output using a 4 Kohm load and oscilloscope.
