Researcher Utilizes Digitimer’s DS8R High Frequency Stimulator

Research Spotlight - Matija Milosevic, PhD.

Dr. Mitija Milosevic utilized various neuroscience equipment including the Digitimer DS8R to study the effects of electrical stimulation on spinal cord elasticity.

The Miami Project to Cure Paralysis was founded in 1985 to gain knowledge and and to develop therapeutic strategies for spinal cord injury and traumatic brain injury.  This prominent institution is considered one of the premier research programs conducting cutting-edge discovery, translational and clinical investigations. Over 175 researchers are developing new treatments for traumatic spinal cord and brain injury, peripheral nerve injury and neurodegenerative disorders including Parkinson’s disease, Multiple Sclerosis, ALS, and Alzheimer’s disease. This includes Dr. Matija Milosevic who is is the Director of Neuromotor Rehabilitation for The Miami Project to Cure Paralysis and an Assistant Professor in the Departments of Neurological Surgery and Biomedical Engineering at the University of Miami. Dr. Milosevic, along with the other researchers, is dedicated to improving the quality of life and, ultimately, finding a cure for paralysis. 

Dr. Milosevic’s lab, specifically, is devoted to developing neuromodulation technologies and therapies for improving the human motor function through an interdisciplinary approach combining engineering methods and neuroscience techniques. Most days are filled with constant research activity with various spinal cord injury participants eager to help in any way they can to achieve Dr. Milosevic's goals. To this end and among other cutting edge neuroscience equipment that Dr. Milosevic’s team utilizes the Digitimer DS8R biphasic charged balanced high frequency electrical stimulator (pictured below) to get a deeper understanding of how electrical impulses can improve spinal cord elasticity and improve mobility.

Since 2016, the Digitimer DS8R has been and continues to be the go-to electrical stimulator used by top researchers to study its effects on the human body. It features a high compliance voltage and can be triggered by a standard TTL compatible input, contact closure foot/hand switch or front panel “single-shot” button. The DS8R can deliver monophasic or biphasic pulses of up to 2ms duration, with an output range of 0-1000mA in 100µA steps (from 400V).

The DS8R is unique among Digitimer’s other triggered pulse stimulators in that it incorporates features that allow external “on the fly” control of stimulus pulse parameters, either via its USB connection and our software GUI/API via third party control software programs. Furthermore, with the connection to the Digitimer D188 Remote Electrode Selector the DS8R can be connected to up to eight different electrode sites which, then, enhances and elevates the research potential of electrical stimulation. With the D188 and a well thought out controlling software program multiple electrode sites can be stimulated at various times with various stimulation parameters. 

Dr. Milosevic’s lab uses both the DS8R and D188.
