Abstract: A method for objectively verifying the efficacy of manipulative therapy is provided. The method includes performing a first dermatomal somatosensory evoked potentials test (82) on a patient (12) to establish a baseline response of the nerve latency period. A manipulative therapy technique (88) is then performed on the patient to relieve nerve root compression. A second dermatomal somatosensory evoked potentials test (90) is then performed, to establish a post-manipulation nerve latency period.

Abstract: Repeat fixation for medical procedures is accomplished using a non-invasive locator, specifically a bite plate (26). The bite plate (26) has at least three fiducial markers (38) on it. The fiducial markers (38) may be LEDs, radiopaque markers for angiography or computerized tomography (CT) imaging or magnetic resonance markers for magnetic resonance (MR) imaging. By detecting the position of the markers (38), the position of features within the patient (14) (such as a brain tumor or other intracranial target to which radiation is to be applied) can be determined with great precision. Since the bite plate (26) has been molded to uniquely fit to the patient's teeth, it may be removed after an initial imaging of the patient (14). The bite plate (26) may then be re-attached one or more times to the teeth and the location of the features will be in a known position relative to the sensed markers.

Abstract: A method and apparatus for determining accurately, both during and after insertion, the full length position of catheters (including implanted ports (64)), tubes (30) and placement guidewires (22) within biological tissue, is disclosed including a transmitter/detector unit (2) having an alternating current (AC) radiofrequency (RF) transmitter with antenna (14), and a radio signal transmitter in the form of a continuous or segmented fine wire receiving antenna (28, 32, 74) situated along the full length of the catheter, guide wire, and implanted port assemblies (22, 30, 64). The guide wire apparatus also includes a tip antenna. These antennae are connected by a removable clip (18) to a wide band RF detector circuit, situated within the transmitter/detector unit (2). The RF transmitter/detector circuit provides a voltage output that is a function of the relative spatial proximity of the transmitting antenna. This proximity is displayed visually to the operator using a sequential linear LED array (8) whose sensitivity is controlled by a gain control knob (10).
