A system and method allows diagnosis of a patient for physiological abnormality such as a neurological deficiency. An involuntary reflex cough event is induced within the patient that activates the nucleus ambiguus and medial motor cell column of the patient and stimulates involuntary cough activated paraspinal muscles in the pelvis of the patient. An electromyogram (EMG) is obtained from the involuntary cough activated paraspinal muscles while inducing involuntary reflex cough and determining its duration. The intra-abdominal pressure (IAP) is determined and the IAP is correlated with the EMG duration of the involuntary cough event within a processing device to diagnose a physiological abnormality such as a neurological deficiency within the patient.

A passive back extensor device for treatment of trigger-point back pain has a base substrate having upper and lower generally planar surfaces. A plurality of protuberances are integral with the base substrate and project from the upper generally planar surface and are arranged in substantially evenly spaced relation and define a pair of spaced rows so as to collectively define an elongate space between the rows. Each of the protuberances is of generally pyramid configuration having a rounded end oriented for passive manual pressure engagement with the paraspinal muscles along an individual's back on each side of the spine and with the elongate space receiving the bony protuberances of the spine. Each of the protuberances is arranged with one of its corners located adjacent a side edge or an end edge of the base substrate so that the planar surfaces and base is oriented in angular relation with the side and end edges of the base substrate.

Devices, kits, and methods for stabilizing the spine and replacing spinous processes removed during spine surgery are provided. The device has a suitable configuration to attach to both spine surgery hardware and to the paraspinal muscles and fascia. The device contains a muscle attachment portion, one or more connectors, and one or more cross connectors. Each cross connector contains a pair of connection portions configured to attach to hardware that is implanted in the spine, such as screw heads or rods. The muscle attachment portion contains a plurality of openings for the attachment of the paraspinal muscles and fascia. Following spine surgery, a surgeon attaches the device to the hardware implanted in the surgical site, and sutures the paraspinal muscles to the openings. Thus the device provides a direct attachment to the paraspinal musculature and fascia, and thereby stabilizes the spine.

A system permits diagnosis of a patient for a physiological abnormality while protecting their airway. An esophageal airway protection device comprises an elongate device body having a distal end for insertion into the stomach through the esophagus and a proximal end. The device includes a main lumen extending the length of the device and an inflatable esophageal cuff carried by the device body mid-esophagus. Emesis and/or reflux is blocked from passing out of the stomach past the esophageal cuff positioned mid-esophagus when it is inflated to protect a patient's airway during an involuntary cough event. At least one electromyogram (EMG) pad is configured to obtain an EMG from an involuntary cough activated paraspinal muscles. A processing device is configured to receive the EMG and process the EMG to determine a physiological abnormality.

For the purpose of realizing of a method of minimally-invasive therapy for spinal canal stenosis, it is intended to provide a therapeutic device capable of stationing an interspinous process spacer without the need of large skin incision or ligamentous tissue incision and also without the need of detaching of the paraspinal muscle from the spine. There is provided an interspinous process spacer comprising conoid screw region (2) to be screwed into a processus spinosus interspace; spacer region (3) disposed in the longitudinal direction of the screw region (2); head region (4) capable of free interlocking with a tool arbitrarily; and through-hole (5) passing through the axial centers of screw region (2), spacer region (3) and head region (4). The processus spinosus interspace can be smoothly enlarged by screwing of the screw region (2) into the processus spinosus interspace. The spacer region (3) is pinched upon passing of the screw region (2) through the processus spinosus interspace to thereby attain enlarging and fixing of adjacent processus spinosus interspaces. The interspinous process spacer can be guided to an interspinous position by inserting a guide member in the through-hole (5) provided along the axial centers of screw region (2) and spacer region (3) and carrying out penetration into the body along the guide member.

A system for dynamically adjusting treatment angle under tension to accommodate variations in spinal morphology during spinal decompression therapy is provided. It provides a tensioning device including a patient-positioning means, a tension-producing actuator, a positioning device, a patient interface device, a control system and a display. The control system with feedback on the resultant tension vector applied to patient spine operationally configured to allow for adjustment of either tension producing actuator position, patient position, or both while applying tension to the patient spine during non-therapeutic tension levels. The control system automatically adjusts tension producing actuator work levels such that the resultant tension vector magnitude remains ideally constant during adjustment of resultant tension vector angle, reducing the risk of eliciting paraspinal muscle contraction due to changes in resultant tension vector magnitude.

The invention relates to a human body vertebral column implanting appliance, in particular to an artificial vertebral plate, which comprises a vertebral plate body. The artificial vertebral plate is characterized in that the vertebral plate body is an arc-shaped netty vertebral plate, side wings are arranged on two sides of the arc-shaped netty vertebral plate, screw holes are arranged on the side wings, netty bumps are arranged on the back side of the arc-shaped netty vertebral plate, and meshes are arranged on the arc-shaped netty vertebral plate and the netty bumps. The invention is used for reconstruction by the aid of the artificial vertebral plate after laminectomy in posterior spinal surgery for a human body, coloboma of a vertebral plate is repaired, the human body vertebral plate is imitated, spinal cord compression caused by swelling of posterior tissues of the spinal cord of the human body after the surgery is prevented, completeness of a vertebral canal is kept, the vertebral column of the human body is stabilized, and the spinal cord is protected. During usage, the artificial vertebral plate is fixed on a transverse process or a vertebral pedicle of the vertebral column of the human body by screws via the screw holes on the side wings on the two sides, and paraspinal muscle, supraspinal ligament and the like are sewn on the meshes of the netty bumps. The vertebral plate body is the arc-shaped netty structure, so that the volume of the vertebral canal is guaranteed; and the netty structures of the arc-shaped netty vertebral plate and the netty bumps bring convenience for growth of tissues on two sides so as to realize tissue connection.
