Description
DESCRIPTION
The DS5 Isolated Bipolar Constant Current Stimulator allows computer control of stimulus amplitude and timing parameters and has a maximum constant current output of ±50mA. It was originally designed to speed up and enhance human peripheral nerve diagnostics by facilitating semi-automated nerve excitability tests. However, it also has roles in wider aspects of clinical neurophysiology research, including psychological, vestibular system and nociceptive testing. More recently pairs of DS5’s have been used in research investigating the new technique of temporal interference stimulation (TIS), which may offer a non-invasive, but targeted alternative to deep brain stimulation and other therapies. The DS5 Isolated Bipolar Constant Current Stimulator is a CE marked medical device under the European Medical Device Regulation.
The DS5 is controlled by an analogue voltage input or “command” signal which it translates into an isolated constant current stimulus (up to ±50mA), precisely replicating the shape of the input waveform. As a result the DS5 should be of interest to anyone wishing to control surface electrical stimulation protocols via software/hardware combinations capable of producing a suitable command voltage waveform e.g semi-automated pain research or sensory threshold testing. The DS5 has also been employed for galvanic vestibular stimulation (GVS), transcranial AC stimulation (tACS) and temporal interference stimulation (tIS) protocols.
The DS5 was developed in collaboration with Prof. Hugh Bostock (UCL, London) for use with QtracW, a nerve excitability stimulus control, acquisition and data analysis software package, also available from Digitimer. This software semi-automates tests of nerve, muscle or cortical excitability using threshold tracking methods.
