The invention concerns a prosthesis wherein the contact surfaces of the femoral part (i), the insert (3) and the knee joint are defined by the combination of two curves, a spiral-type curve in the saggital plane following an undulating curve (sinusoidal) in the frontal plane. The latter comprises two concave lateral parts and a central dome-shaped convex part, the three parts being connected without any angulation, protuberance, or flat parts or bends and providing continuous medio-lateral contact on the three zones, from complete extension to complete bending, and a concave-convex nesting in the central zone.

A two-dimensional (2D) chemical shift correlated MR spectroscopic (COSY) sequence integrated into a new volume localization technique (90°-180°-90°) for whole body MR Spectroscopy. Using the product operator formalism, a theoretical calculation of the volume localization as well as the coherence transfer efficiencies in 2D MRS is presented. A combination of different MRI transmit/receive rf coils is used. The cross peak intensities excited by the proposed 2D sequence are asymmetric with respect to the diagonal peaks. Localized COSY spectra of cerebral frontal and occipital gray/white matter regions in fifteen healthy controls are presented.

The present invention provides systems, apparatus and methods for treating nerve disorders in the brain. An electrode is introduced into a patient's sinus cavity and an electrical impulse is applied to the electrode to modulate one or more target nerves in the brain to treat the disorder. In preferred embodiments, the electrode is positioned within a sinus cavity adjacent to or near the frontal cortex of the brain and the electrical signal is sufficient to modulate, stimulate and/or inhibit nerves within the frontal cortex. The electrode may be movable between a collapsed or compact configuration for introduction into the sinus cavity and an expanded configuration for contacting tissue within the sinus cavity to deliver the electrical impulse through the tissue to the target nerves in the brain.

An objective of the present invention is to provide a safe and effective vaccine therapy for Alzheimer's disease. A minus strand RNA viral vector carrying amyloid gene was constructed, and administered intranasally to 24- to 25-months-old APP transgenic mice. The level of serum anti-A 42 antibody was determined and showed to be markedly higher than the control. The results of histological investigation showed that the administration of a vector of the present invention markedly reduced senile plaques in all of the frontal lobe, parietal lobe, and hippocampus. The brain A level was also markedly reduced. Furthermore, the administration of a vector of the present invention did not result in lymphocyte infiltration in the central nervous system.

A method and apparatus are disclosed that automatically interject brain activations into video imaging activities or other activities of daily living. During a video game, for example, an interrupt causes a pause in the game and a commencement of an activity involving but not limited to bilateral portions of the body, the peripheral vision of the game-player, and a visual pursuit-type and saccadic-type action on the video screen. Alternatively, the brain activation can be merged into the content of the video game so as to be generally indistinguishable to the user. Automatic feedback from the system encourages more frequent brain activations when performance is determined to be diminished and less frequent brain activations when performance is determined to be enhanced. The combination of events in the activity is believed to engage the frontal lobes of the brain as well as other brain structures and stimulate brain health.

In a method for determining the pelvic inlet plane of the pelvic bone, which is defined by the following three points of the pelvic bone:

point A: spina iliaca anterior superior left

point B: spina iliaca anterior superior right

point C: symphysis pubis,

by non-invasive determination of the position of one of the two points A or B and point C, in order to also be able to carry out this determination whenever point A or point B is not accessible, it is proposed that the position of the following points of the pelvic bone be additionally determined non-invasively:

point D: spina iliaca posterior superior left

point E: spina iliaca posterior superior right,

and that the position of the pelvic inlet plane be calculated from the position of the non-invasively determined points A or B, C, D and E.

The present invention relates to an automatic cardiopulmonary resuscitation (CPR) device which, even in the middle of performing cardiopulmonary resuscitation, can measure an electrocardiogram and oxygen saturation, can measure an electroencephalogram so as to detect in real time a brain activity indicative of the degree of blood circulation in the brain, has a defibrillation function, can use a brain activity index as a CPR signal indicating the degree of cardiopulmonary resuscitation, and can remotely monitor biometric signals at a pre-hospital stage. The present invention provides a cardiopulmonary resuscitation device comprising: an electroencephalogram detection unit for detecting an electroencephalogram signal from the frontal lobe; and a calculation processing unit for detecting a brain activity index, which is used as a CPR signal indicating the degree of cardiopulmonary resuscitation, from the electroencephalogram signal received from the electroencephalogram detection unit, wherein the calculation processing unit derives, as the brain activity index, one or more of the burst suppression ratio (BSR), the beta ratio, and the SynchFastSlow (relative synchrony of fast and slow wave, SFS). The calculation processing unit eliminates noise from the electroencephalogram signal received from the electroencephalogram detection unit, and derives the beta ratio from the electroencephalogram signal, from which noise has been eliminated, using the following formula: Beta Ratio = log[spectral power (30-47 Hz)/spectral power (11-20 Hz)] (where, spectral power (30-47 Hz) denotes the spectral power in the 30-47 Hz band of the electroencephalogram, and spectral power (11-20 Hz) denotes the spectral power in the 11-20 Hz band of the electroencephalogram).

A mental impairment detection system and non-invasive method of detecting mental impairment of a user are provided. A test (e.g., an inhibitory reflex test or a sustained attention test) is administered to the user, brain activity in a frontal lobe of the user is non-invasively detected while the test is administered to the user, and a level of mental impairment of the user is determined based on the brain activity detected in the frontal lobe of the user.

A method of commanding and controlling a mobile apparatus (wheelchair) based on the assimilation of visual parameter and brain activity data includes validating a desired position of gaze (the iris) in the environment using the physiological brain characteristics of the potentials mentioned in P300 and SSVEP. These supply a control unit and are used to assess the user's state of mental fatigue using an algorithm based on the theory of evidence. A unit detecting the user's emotional state is also implemented using the alpha and beta waves from the parietal, central and frontal region of the cerebral cortex and the user's heart rhythm. The assimilation between these two units makes it possible to define a mode of operation in real time: manual, semi-autonomous or autonomous, which corresponds to the user's emotional or fatigue states as well as the characterization of the environment (safe path, detection of obstacles, locked situation).

Provided is a health diagnosis apparatus and method in which brain waves are sequentially measured from the frontal lobe of a human body that is to be diagnosed when the eyes are in an eyes-open and eyes-closed state, the measured brain waves are fast Fourier transformed to then be accumulated, and then the health conditions of the respective portions of the human body can be determined according to the patterns with respective frequencies. The health condition diagnosis method includes measuring brain waves; performing a fast-Fourier-transform on the measured brain waves; classifying the frequency-based brain wave data into opened and closed eye state brain waves to thus accumulate the classified result; finding a specific frequency and a pattern thereof which repeats from the accumulated brain wave data; correspondingly connecting the frequency and the respective portions of the human body based on the specific frequency pattern; and determining the health condition of the human body. The frequency-based health condition determination is based on clinic test results.

This invention is a validation process for ipsative assessments. Respondents are connected to an Electroencephalograph (EEG) and some or all of the ipsative assessment questions are asked again while connected to the EEG. The EEG measuring frontal lobe responses in terms of gamma waves is compared with the assessment questions. Positive responses provide one frontal lobe response in terms of gamma waves, negative or false answers provide a different gamma response and neutral questions provide a neutral gamma response. Reading the responses then tells whether the respondent initially responded with integrity, if so the assessment is validated.
