A system for treating pain consisting of an "add-on" module integrated within the implantable pulse generator (IPG) component of IPG spinal cord stimulators, or, alternatively, integrated within the radiofrequency (RF) transmitter component of RF spinal cord stimulators. The system automatically and continuously monitors, measures, and classifies multiple patient physiological parameters without human intervention. The system also classifies qualitative perceptive changes felt by the patient. On the basis of this input vector information, the system automatically and continuously generates the most appropriate stimulation programs to improve, alleviate, or eliminate the patient's pain without human intervention. The system automatically and continuously adapts itself to both quantitative physiological changes within the patient and qualitative perceptive changes felt by the patient.

A system is provided for stimulating and measuring performance of nerves which utilizes a novel system of electrodes. A large moistened absorbent pad-type electrode is used to provide one electrical contact with the body. A small moistened absorbent pad-type electrode in a handheld pencil-like configuration is used to provide a second, more targeted electrical contact with the body. By placing the large electrode along or near the spine, the pencil-like electrode may be used to excite and measure nerves on opposite sides of the body. In this manner, the electrical contact made by the large electrode is a constant during the measurement, both as to distance from the tested nerve site, and as to electrical conduction to the body. This arrangement provides more reliable and repeatable measurements. It also avoids patient discomfort associated with needle-like probes, tape-on probes, and other probes which involve discomfort. In another aspect of the invention, a galvanic skin response measurement system is incorporated into the nerve performance measurement system and is used to determine threshold nerve sensing events, rather than relying upon oral input from the patient. In this way, actual events are detected which do not rely for their accuracy upon the truthfulness of the patient. In another aspect of the present invention, the 2000 Hz signal used to stimulate the type A-Beta nerves is amplitude modulated with an adjustable sine wave signal in the range of about 5 Hz to about 700 Hz in order to obtain increased patient sensitivity to the combined signal.

A method and apparatus include a therapeutic or developmental apparel that includes hardware and/or software for stimulating a muscle. Such apparel may comprise, for instance, of: a glove, a uniform, a shoe, a sock, a vest, a sleeve, a shirt, a hat, a helmet, a brace, a suspender, eye wear, a pad, jewelry, a watch and pants. A muscle of a user may be stimulated by the garment as the user moves, such as a when a golfer practices her swing. Combining such muscle stimulation with the act of practicing the movement of the swing has a synergistic effect of training the muscle as it builds strength. Similarly, a partial paralytic may regain strength in their hand by wearing a vest or other garment configured to transcutaneously deliver a stimulating signal. Where desired, the garment may include at least one electrode configured to deliver a stimulating signal to the wearer. In another or the same embodiment, wired electrodes may extend from the garment or an adjacent signal generator to the wearer. This configuration may allow other, targeted muscles to be concurrently stimulated while the user wears the garment.

A method and apparatus generate resonant sequences having pulses optimally spaced and configured to realize uniform contractions in a musculature. Namely, each subsequent pulse maintains tension within sarcomeres of the musculature as the resonant sequence propagates inwardly to progressively stimulate the entirety of the musculature. Variation in the width, spacing, polarity and/or amplitude of the pulses comprising the resonant sequence further overcomes accommodation and nutritional depletion while minimizing discomfort.
