DS7A - Constant Current Stimulator
Stimulating Electrodes
The choice of electrodes to use with the DS7A is dependant upon the specific application and should be
determined by the clinician in charge of the procedure. A wide variety of proprietary electrodes are available
from Digitimer, ranging from small saline soaked felt pads (ideal for stimulating the ulnar nerve on the
patients wrist) through to large self-adhesive electrodes (needed to obtain the low electrode impedance
necessary when stimulating large muscles such as the quadriceps). Please contact us for further details.
Due to the possibility of generating high current densities, the use of needle electrodes is NOT
recommended.
Current densities for any electrode exceeding 2 mA/cm
2
may require the special attention of the operator.
