The invention relates to a device for assessing the haemodynamic response generated by the spinal column in response to a suprasensory stimulus applied to a peripheral nerve (median or posterior tibial) using functional near-infrared spectroscopy (fNIRS). The device comprises three main components: an electrical stimulator, an optical recording unit and a signal control and processing module. The device allows changes in local haemodynamic parameters in response to the neural activation of the spinal cord by means of electrical stimulation of a peripheral nerve to be assessed in a non-invasive, comfortable, harmless, portable and low-cost manner in the home. The invention also comprises a corresponding method for using the device and monitoring bone marrow function.
