TECNALIA tests a surface electrical stimulation system used to analyse patient's sensitivity to a stimulus in the lower back and/or leg area

The EQST system facilitates the sensory testing of large areas of the body using multi-field electrodes and semi-automatic analysis

On November 4, the clinical trials for validating the Electrical Quantitative Sensory Testing (EQST) system for Failed Back Surgery Syndrome started in the Multidisciplinary Pain Management Unit at the Ramón y Cajal University Hospital (Madrid). Neuropathic pain is assessed in those patients with lower back and/or lower limb pain, who have undergone lumbar surgery, and who are candidates for treatment by means of spinal cord electrical stimulation therapy.

The differential value lies in carrying out a quantified and multi-dimensional sensory analysis thanks to multi-field electrodes and their ability to stimulate different nerve fibres in a selective manner. Over the next few months the clinical trial will continue and the EQST system will be analysed on up to 30 patients.

Said trial will be carried out in accordance with the protocol approved by the Ethics Committee for Research into Medicinal Products (CEIm) of the Ramón y Cajal University Hospital and the Spanish Agency for Medicines and Medical Devices (AEMPS).
