Abstract:
PROBLEM TO BE SOLVED: To provide a motor function evaluation device and a motor function evaluation method, capable of comprehensively and easily evaluating a motor function of a subject.SOLUTION: A motor function evaluation device includes: a measurement base plate; a load measuring circuit 14 for measuring temporal change of a load of a subject applied to the measurement base plate; and a CPU 24 for obtaining a balance ability index of the subject from the temporal change of the load measured by the load measuring circuit 14. The CPU 24 obtains the balance ability index from a time interval between a time when the subject stands up to maximize the load applied to the load measuring circuit 14 and a time when the change of the load stabilizes.
Abstract:
The present disclosure provides a provisional tibial prosthesis system (30A) for a set of prosthetic knee joints for im-plantation in a natural knee, the provisional tibial prosthesis system including a bearing component (32A) and a bearing support (34A, 38A), the spacing (36A) of the bearing component from the bearing support is adjustable to allow for representation of a variety of different sized final tibial prostheses. In this system, only one provisional bearing component corresponding to each level of constraint is needed and shims (e.g. 36A) are used to adjust the spacing of the bearing component from the bearing support. The shims are slidably insertable between the bearing component and the bearing support in an anterior/posterior direction to allow for adjustment of the spacing of the bearing component from the bearing support. The number of provisional components needed during knee surgery is reduced and adjustment of the system only requires the knee joint to be distracted by a distance equal to the height of a particular shim.
Abstract:
The visual and/or visualization skills of a subject may be tested and/or trained using systems and methods in accordance with the present invention. Visual stimuli may be presented to a test subject. Measurements relating to the performance of the subject, such as stability information, eye movement data, physiological information, or other information, may be made both with and without visual stimuli being provided to a subject. Similar measurements may be made while the subject visualizes the visual stimuli, and the collected data may be compared to evaluate the subject's ability to visualize visual stimuli. Secondary stimuli may also be provided to subject as part of this process, or mental activities may be required by subject as well.
Abstract:
The present invention presents a shoe or insole fitting navigation system including a set of foot sole pressure measuring sensors for measuring foot sole pressure distributions; a set of TV cameras for taking foot images; a processor; and a monitor screen. The present system acquires right and left foot sole pressure data, acquires right and left foot images, computes a foot sole gravity center position of each foot, computes an outer dimension of each foot, and determines bias in gravity center balance of each foot accurately based on the foot sole gravity center position of each foot and the outer dimension of each foot. In addition, the present system determines an abnormal foot symptom of each foot, and selects a shoe or insole of each foot based on the determined bias in gravity center balance and the determined foot symptom.
Abstract:
PROBLEM TO BE SOLVED: To effectively use an element group even in a case where a detecting zone is limited to a specific zone to improve the detection accuracy of a user.SOLUTION: In a first human detection sensor 28, a part of detection elements 314 constitutes effective detection elements 314A through 314D that are capable of detecting infrared through a monitoring window 304B, while the others constitute non-effective detection elements 314E through 314P that are incapable of detecting infrared. Accordingly, a reflection mirror 320 is arranged at a position facing the optical axis of the non-effective detection elements 314E through 314P so that the optical axis is deflected to pass through the monitoring window 304B. The arrangement of the reflection mirror 320 causes the optical axis of the non-effective detection elements 314E through 314P to be deflected by the reflection mirror 320 so as to pass through the monitoring window 304B, enabling the non-effective detection elements to be used as effective detection elements so that the detection zone F1 of the original effective detection elements 314A through 314D is interpolated.
