Mediracer Ltd was founded in 2002 to develop Point of Care products in the field of clinical neurophysiology for patient examinations adapted to the needs of primary health care. The target was to develop reliable and cost-effective products for examination of the most common neurophysiological disorders on primary health care level, requiring only a short training for the operators.

Carpal tunnel syndrome (CTS), being the most common nerve entrapment in the upper limb with the incidence of over 3% in the population, was chosen as an application of the first device by Veijo Lesonen, a doctor in clinical neurophysiology and the inventor of the product idea.
