Apparatus for actuating a skeletal muscle of a patient is provided. The apparatus typically includes a plurality of electrodes, which are adapted to be placed in a vicinity of a motor nerve that innervates the skeletal muscle. A control unit, is preferably adapted to drive a current between two or more of the plurality of electrodes, and to configure the current such that a first subset of axons in the nerve is excited by the current and such that a second subset of axons in the nerve is not excited by the current.

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 present invention relates to methods and apparatuses for the detection of neural or muscular activity, analysis of the signals and the subsequent stimulating of neural or muscular tissue based thereon. According to a first aspect of the invention an apparatus for producing a muscular action is provided, comprising a combined sensing and stimulation electrode device comprising at least one neurosense electrode means capable of sensing a nerve signal from a peripheral nerve and at least one stimulation electrode means capable of stimulating a peripheral motor nerve fiber, means for receiving and processing the sensed neurosignals to identify a signal indicative of a specific action, especially a component of the gait performed by the patient and for producing a control signal in response thereto, and means for operating the at least one stimulation electrode means in response to the control signal to produce a stimulation of a peripheral motor nerve fiber.

Apparatus and method for making and using devices that generate optical signals, and optionally also electrical signals in combination with one or more such optical signals, to stimulate (i.e., trigger) and/or simulate a sensory-nerve signal in nerve and/or brain tissue of a living animal (e.g., a human), for example to treat nerve damage in the peripheral nervous system (PNS) or the central nervous system (CNS) and provide sensations to stimulate and/or simulate “sensory” signals in nerves and/or brain tissue of a living animal (e.g., a human) to treat other sensory deficiencies (e.g., touch, feel, balance, visual, taste, or olfactory) and provide sensations related to those sensory deficiencies, and/or to stimulate (i.e., trigger) and/or simulate a motor-nerve signal in nerve and/or brain tissue of a living animal (e.g., a human), for example to control a muscle or a robotic prosthesis.

A method for cryogenically treating a target tissue comprises providing a cryogenic device having one or more tissue penetrating needle probes, and advancing the one or more tissue penetrating needle probes through skin disposed above the target tissue into the target tissue. The target tissue comprises a motor nerve. The method also includes cooling the target tissue with the one or more tissue penetrating needle probes, and temporarily disrupting signal conduction from the motor nerve thereby preventing contraction of a muscle operably coupled to the motor nerve. This reduces or eliminates hyperdynamic wrinkles of a patient's face.

Neural bridge devices for providing ionic communication across damaged or separated portions of a neuron, or between a neuron and an electronic device, are disclosed. The neural bridge devices can include an ionically conductive polymer that may functionally replace the biological conduction of action potentials along an axon, to restore sensory or motor nerve function, and may enhance neuronal healing.

A surgical method for gastrocnemius muscle reduction is provided. The method may search for a motor nerve associated with a gastrocnemius muscle of a patient, inserts a probe by penetrating an epidermis around the motor nerve and locates a tip of the probe in the motor nerve, stimulates the motor nerve through supply of an electric signal to the probe, thereby shutting down the motor nerve.

The invention relates to the technical field of the computer and discloses a method and a system for monitoring a motion action condition. The method comprises the steps of: outputting a reference signal at a preset frequency; acquiring a trigger signal trigged by the action of the user according to the frequency of the reference signal in real time; respectively comparing the frequency of each trigger signal with that of the reference signal; and determining the action response condition of the user according to the frequency compared result of the trigger signal and the reference signal. The system comprises a reference signal output unit, a trigger unit acquiring unit, a frequency discriminating unit, an analyzing unit and the like. According to the method and the system, the frequency of the trigger signal corresponding to each action is compared with the frequency of the reference signal, the action response condition of the user, which is judged according to the frequency compared result, conforms to the reality better, and conforms to a principle of the motor nerve coordination theory better.

This invention relates a kind of contact intelligent alternate device based on move body's action which concludes: item loop, angular transducer, signal transfer module, digit signal processor. The detection method of the invention bases on the move body wearing item loop and makes the angular transducer installed in the item loop shape changed by the move body's movement and then judges the movement location of the move body; the deformation variable of angular transducer is transferred to the analog variable through the signal transfer module and then outputs to the digit signal processor and the digit signal processor transfers the analog variable to the digit variable by using the inner AD transfer module of it and then analyses the multiple angular transducer according to the fusion algorithm then judges the location of the present move body. It resolves the problem that the measurement for the move body is not precise enough by using the non-contact transducer. This invention offers a kind of simple, convenience, high measurement precision interactive device for the high vertebra injury and motor nerve disease patient and other demand occasions.
