A head mounted display includes a head suspension apparatus and a display coupled thereto. In a stationary state, the display is maintained in a desired position relative to the head suspension apparatus. Further, in a release state, the display is always freely movable both vertically and horizontally relative to the head suspension apparatus. In addition, the display may also always be freely rotatable about an axis of the display as well as vertically and horizontally. The coupling of the dis...

The early care of low-back pain using a series of stretching exercises that include knee to chest stretching, straight leg rising stretching, sitting toe touches and lumbar flexion stretching aid the gradual healing of low-back pain without the need for medical treatment. With such stretching, sufficient ability to bend the body in flexion is achieved. Further, the strengthening of the lumbar muscles with graded weight lifting continues a path to recovery and control over what would otherwise be...

A method for controlling the spread of HIV/AIDS and other infectious diseases. Individuals desirous of reducing the risks of infection and preventing the spread of such diseases voluntarily participate in a testing program whereby regular periodic screening tests are performed to indicate the infection status of each such individual for any of several infectious diseases. The infection status information is coded for each individual and is stored in a confidential database. An individual can acc...

Methods and devices are provided for detecting the presence of edema in a mammalian host. In the subject methods, a cross-sectional dimension of at least one limbic extremity, preferably a lower limbic extremity such as an ankle or foot, is measured to obtain a measured value. The measured value is then compared to a control value and any difference is identified. The difference is then related to the presence of edema in the patient. The subject methods find use in the diagnosis and management ...

Percutaneous implants fabricated from a core or substrate of a low modulus metal coated with blue to black zirconium oxide or zirconium nitride. The coating provides enhanced thrombogenicity, biocompatibility, blood compatibility, corrosion-resistance, friction and microfretting resistance, durability, and electrical insulation, where applicable. The coatings may be applied to low modulus metallic substrates by physical or chemical vapor deposition as well as other ion-beam assisted methods. Pre...

Methods and apparatus are disclosed for treating motion sickness. In a preferred embodiment a method of the invention comprises operating eyewear having shutter lenses to open said shutter lenses at a selected operating frequency ranging from within about 3 Hz to about 50 Hz. The shutter lenses are opened for a short duration at the selected operating frequency wherein the duration is selected to prevent retinal slip. The shutter lenses may be operated at a relatively slow frequency of about 4 H...

Methods are provided for intramuscular needle diagnosis and treatment of muscle pain that is believed to be the result of sympathetically mediated spindle spasm. Two simultaneous needle EMG needle recordings are used to establish the presence of and magnitude of the "trigger points" in painful muscle. The abnormal muscle activity so identified can then be treated by blocking the sympathetic activation muscle blocker or other agent that would have the same effect of inhibiting the abnormal muscle...

Articles of equipment such as swabs and surgical instruments are provided with a machine readable information source such as a bar code, and are monitored during surger by means of a system which comprises a bar code scanner (19) and a computer (3) on which information read by the scanner can be stored. The system may include scales (9) for weighing the equipment so that body fluid absorbed by absorbent articles such as swabs can be determined.

Disclosed is a prosthetic bulking device for implantation below the mucosa to treat gastroesophageal reflux disease. The bulking device comprises a flexible body which may have one or more attachment surfaces to allow tissue ingrowth from the adjacent tissue. The bulking device cooperates with residual lower esophageal sphincter (LES) function to increase LES closing pressure.

The invention concerns a method and an arrangement for determining the position of a marker in an organic cavity, in particular for establishing local passage speeds within the framework of the medical diagnosis of the stomach-bowel tract. The object of the invention is to provide a solution which ensures position-determining accuracy of greater than 1 cm in all three co-ordinate directions and permits position-determining times of 10 seconds and less in each case. According to the invention, th...
