The embodiment of the invention discloses a testing device. The testing device comprises a cable, a connecting assembly and a stimulating assembly which are connected in sequence. Wherein the connecting assembly is provided with a limiting groove for limiting and fixing the implantable electrode, a plurality of conductive elastic sheets in conductive connection with the cable are arranged in the limiting groove, and the conductive elastic sheets are used for being detachably and electrically connected with a wire of the implantable electrode, so that the implanted implantable electrode is tested. The stimulation assembly is provided with a conductive probe electrically connected with the cable, and can apply a test electric signal to the nervous tissue to carry out a stimulation reaction test, thereby assisting in accurately confirming the position of the target spot. According to the testing device, the electrode testing function and the nerve stimulation testing function are integrated into a single device, the structure is compact, operation is visual, and the accuracy, smoothness and convenience of an operation are remarkably improved.

The present device aims to create ideal conditions for performing human profiling, assessment and testing processes, in a controlled, simple, accurate, inclusive and distraction-free manner. In order to achieve this aim, the device offers a minimalist, dedicated interface, having a simplified physical keypad that can have various formats depending on the application. During the performance of the test, built-in or peripheral cameras and sensors can collect additional information relating to the attentional, cognitive, physiological and emotional state of the user. This data is processed by the device in order to generate information that can be combined with the other results to produce an even more in-depth assessment of the subject being tested. The entire assessment process can take place in online mode, allowing immediate synchronization with a server, or in offline mode, allowing subsequent synchronization with a server or the downloading of the data directly to a computer. In both cases, an administrative dashboard accessible via the device or via the web can be used to download or create new tests, update the existing tests, register users, view the results and manage the entire assessment process. Finally, the possibility of presenting the test stimuli by means of virtual reality goggles further increases the potential uses and versatility of the equipment.

The present invention provides improved methods for positioning of an implantable lead in a patient with an integrated EMG and stimulation clinician programmer. The integrated clinician programmer is coupled to the implantable lead, wherein the implantable lead comprises at least four electrodes, and to at least one EMG sensing electrode minimally invasively positioned on a skin surface or within the patient. The method comprises delivering a test stimulation at a stimulation amplitude level from the integrated clinician programmer to a nerve tissue of the patient with a principal electrode of the implantable lead. Test stimulations are delivered at a same stimulation amplitude level for a same period of time sequentially to each of the four electrodes of the implantable lead. A stimulation-induced EMG motor response is recorded with the integrated clinician programmer for each test stimulation on each electrode of the implantable lead via the at least one pair of EMG sensing electrodes so as to facilitate initial positioning of the implantable lead at a target stimulation region.
