Abstract:
A combination electronic communication and medical diagnostic apparatus includes a first component for transmitting or receiving a remote communication signal and a second component for generating vibration to be used in a medical diagnosis. The apparatus functions as a beeper/pager or cellular phone, as well as a medical diagnostic tool to detect and/or monitor neuropathy.
Abstract:
An automated process of making a medical test implement, such as a LEAP Testing Implement, includes the steps of providing a handle element, providing a deformable test element, and mechanically mating the deformable test element to the handle element so that at least a portion of the deformable test element extends from the handle element. The deformable test element deforms when a predetermined load is applied thereto.
Abstract:
A non-invasive quantitative somatosensory method is provided for evaluating erectile dysfunctions and involves the applications to the glans penis of different temperatures in increments of about 1null C. until the patient can correctly identify which temperature starting at an ambient temperature was warmer for at least two consecutive times. The method of this invention provides a relatively simple procedure to assess a patient's neurological response to therapies. Incremental decreases in temperature can also be used to assess a patients's neurological response. The method of this invention can also be supplemented, if desired, by determination of the spatial perception threshold and/or the application of pressure, i.e., the sensitivity to touch determination to provide a two-point determination.
Abstract:
A method and apparatus for implementing a training regimen which addresses motor control problems accompanied by sensory degradation. Accordingly, the training regimen is applicable to motor control disorders associated with a variety of different causes, including traumatic injury, disease, aging and gradual “occupational” type injury. For example, in an individual suffering from repetitive strain injury (RSI), the disabling motor control problems are often accompanied by sensory problems. These sensory problems appear to be caused over time by harmful attended rapid repetitive movements resulting in undesirable changes in the somatosensory, proprioceptive and/or kinesthetic ability of the affected regions of the individual. The present invention hypothesizes that repetitive delivery of simultaneous or nearly simultaneous afferent sensory inputs, under attended conditions of high cognitive drive, results in a learning-induced integration of the representation of the individuality of otherwise differentiable parts of the subjects thereby degrading the sensory feedback loop necessary for normal motor control. What started out as a degradation of the sensory feedback capability, essential for proper motor control, eventually manifests over time as a motor control problem. Thus, motor control problems which are accompanied by sensory degradation can be alleviated by a regimen of remedial re-differentiating sensory training of the affected regions of the individual. Accordingly, the training regimen differentially stimulates two locations within the afflicted portion of the individual. Feedback from the individual indicates the degree of difficulty the individual has in sensing differentially between the two locations. The stimulation is then adapted to the individual based on the feedback. Adaptation includes increasing the distance between the two locations and/or changing the spectral or temporal characteristics of the stimuli.
Abstract:
An apparatus and method to objectively measure sensory discrimination thresholds at a test site in the upper aero digestive tract of a patient. A time and pressure controlled puff of air is delivered to the input of a Y-shaped tube; one output branch of the Y-shaped tube delivers the puff of air to the patient and the other output branch delivers the puff of air to a pressure transducer, for measurement and display of the pressure.
Abstract:
The present invention describes computer-implemented methods and apparatus for treating motor control and somatosensory perception deficits. The motor control and somatosensory perception deficits may have their genesis in a wide variety of issues ranging from injury, disease, or a gradual degradation of motor control over time due to repetitive strain, for example. By administering a computer-implemented training regime directed to improve sensory feedback and motor control, abnormal motor control and somatosensory perception may be substantially improved. The computer-implemented training regime includes somatosensory perception and motor control exercises which may be flexibly administered. Several training apparatus are described for implementing the somatosensory perception and motor control exercises. The training apparatus described herein are capable of driving improvements in temporal, spatial and intensity resolution of somatosensory feedback. In addition, the apparatus allow the training to be monitored and adapted on a quantitative basis as treatment proceeds. Advantageously, this provides a more accurate and effective training tool for treating motor control deficits. Further, the computer-implemented methods and apparatus allow treatment to be administered in the convenience of the person's own home and on a daily basis.

Abstract:
The working quality of the human brain is measured with this method and apparatus by determining the highest frequency at which a subject can discriminate between synchronous and asynchronous pairs of two simultaneously presented periodic non-verbal stimuli: the higher this frequency (synchronism threshold) is the faster the brain of the subject can process information using the sensory function tested. The periodic stimuli provided to the subject and preceded by appropriate mask stimuli may be pairs of visual, tactile, electrocutaneous, and/or auditory stimuli within the same sense modality, or intermodal between two different senses. The apparatus generates the stimuli and indicates the nominal frequencies of the stimuli and threshold. The frequency threshold is determined by means of an adaptive staircase procedure in which the frequency is decreased after wrong responses and increased after correct responses.
Abstract:
A diagnostic device and method for determining the presence of a Tinel sign in a patient by providing a calibrated striking unit for use at a selected point along a regenerating nerve and said results of the striking being analyzed with respect to that of a healthy nerve.
