Apparatus and methods for performing spinal disc lesioning procedures while monitoring the temperature near the spinal nerve roots. A needle containing a thermocouple and an injection bore may be placed between the disc and a nerve root. Temperature near the nerve root may be monitored during the lesioning procedure and if raised to a point where damage to the nerve could occur, the procedure may be stopped before damage is done. Coolant may be injected through the injection bore to lower the temperature near the nerve root. Additional dual purpose needles may be placed on the disc adjacent the opposite nerve root or in the spinal canal at the level of the disc for additional control. A hollow, flexible tip electrode needle may be used to repair and lesion the disc tissue. Prior to lesioning, the electrode may be stimulated to assess motor nerve response and avoid motor nerve damage.

The invention relates to a combined type bionic quadruped robot controller, which is in a structure similar to a vertebrate nervous system, wherein the controller is divided into a decision layer, a planning layer and an execution layer which respectively correspond to a higher nervous center, a lower nervous center and a motor nerve of an animal. The decision layer for realizing that the robot senses the working environment and generates corresponding motion decision instructions consists of an ARM9 (advanced RISC (reduced instruction-set computer) machine 9) and an environmental information acquisition system, and a real-time operating system is embedded in the ARM9. The core of the planning layer is a walking pattern generator, and is used for planning and solving the motion parameters of each joint according to the decision instructions from the upper layer. The execution layer for controlling the current, the position and the speed of a driving motor in three closed loops consists of a motor controller using a digital signal processor as the core. Data can be effectively transmitted among the three layers in real time through a dual-port RAM (random-access memory) and a CAN (controller area network) bus network. The combined type bionic quadruped robot controller disclosed by the invention has the characteristics of high reliability, high flexibility, extension easiness and maintenance easiness, and has a broad application prospect in the technical field of bionic legged robots.

A method of monitoring relative nerve health and the presence of neuropraxia is described. The methods utilize the integration of a waveform function of an elicited or monitored nerve response to provide an indication of the strength of a detected signal from a nerve and thus the relative health and integrity of the nerve. In some embodiments motor nerve stimulation innervates muscle and an EMG waveform is obtained in response thereto. The integration under the waveform is expressed and an indexed value indicating a percentage of a certain threshold value. Methods set forth provide a more reliable status of a nerve in real-time and allow action to be taken to reduce neuropraxia or prevent permanent nerve damage.
