Abstract: A limb movement function evaluating method and the implantation system are provided. The aforementioned system includes a limb fixing device, limb guiding device, driver, actuator, impedance detector, and movement function analyzer. The limb fixing device is used to fix the first end of the user limb. The driver is used to guide the second end of the user limb through the actuator so as to make the second end moving relatively to the first end. The impedance detector is further connected to the driver so as to measure mechanical impedance where the movement of the user limb responses to the driving point of the driver. Finally, the limb movement analyzer compares the measured mechanical impedance and the movement path of the user limb so as to form a limb movement function curve. Therefore, the medical staff can make accurate rehabilitation evaluation according to the limb movement function curve.

Abstract: A tool for predicting that a person is likely to be abnormally hydrated over a future time interval, and in some cases to alert the person or a medical professional to intervene. From a series of physiological measurements, a tissue electrical impedance spectrum curve, which comprises a phase spectrum curve in an embodiment, is determined and changes in the shape of the curve are ascertained. The measurements may be received using one or more sensors worn by the person. In some embodiments, current and historic spectrum curvature are applied to an evolutionary algorithm, such as particle-swarm optimization (PSO) or differential evolution (DE), to determine an inference regarding the persons future hydration status. In one embodiment, a statistical forecast for the next epoch immediately beyond the present one, is determined.

Abstract: There is provided herein a motion-based evaluation of reaction time that utilizes motion detection hardware of a mobile device to determine auditory and visual stimulated reaction time. In an embodiment, the subject holds a mobile computing device equipped with built-in triaxis accelerometer and gyroscope with both hands at arms length away from the face. A visual or auditory stimulus is then presented on screen via a software application that also records the response time for the individual to initiate a movement of the device. A simple reaction time test could include the movement of the device in any direction that exceeded a threshold of movement beyond what would be expected from static holding. An embodiment of a choice reaction time test would provide for specific directional movements as it related to an instructed stimulus.

Abstract: A system for assessing knee movement of an individual comprises: a goniometer with a central body portion; a first adjustable leg mounted for movement with respect to the goniometer to represent a lower leg measurement of the individual; a second adjustable leg mounted for movement with respect to the goniometer to represent an upper leg measurement of the individual; and a base board marked with indicia to measure a linear position of a heel of the individual when a knee of the individual is at maximum flexion. The distal end of the first adjustable leg and the distal end of the second adjustable leg are positioned on the base board, with the first adjustable leg and the second adjustable leg in a fixed position relative to the goniometer, to determine an angular measurement of the knee of the individual at maximum flexion by referencing indicia on the goniometer.

Abstract: In a threshold estimation apparatus, a setting unit sets an initial intensity value for each electrode. A selection unit randomly selects an electrode. A stimulation unit, via the selected electrode, stimulates a living subject at an intensity set for the electrode. A detection unit detects the presence or absence of a response evoked by the stimulation. An update unit reduces or increases the intensity associated with the selected electrode, based on the presence or absence of the response evoked by the stimulation. An estimation unit, if the thus updated intensity associated with each electrode satisfies a convergence condition, estimates a convergence value as a threshold associated with the electrode. The threshold estimation apparatus repeats these processes until thresholds associated with all electrodes are estimated. If the same electrode was consecutively selected, the time interval between a stimulation and a subsequent stimulation is adjusted.

Abstract: The invention is a system and method for measuring visual acuity. The system comprises a computer or projector adapted to project a computer generated image of an optotype on a surface, e.g. a computer display screen or a screen on a wall, and a control unit. The computer or projector is adapted to project the optotypes with a steadily changing size as a continuum of images. The testing is carried out by changing the optotype size in both directions in order to compensate for the reaction time of the patient. For example, starting with a large optotype, the size is steadily decreased until the patient signals that he can no longer read the optotype. The test then continues starting from a small optotype and steadily increasing the size until the patient signals that he can read the optotype.

Abstract: A suction drain device of a disclosed liquid collecting apparatus actively pushes and pulls blood. This achieves liquid collection at high speed even under decreased pressure depending on a physiological state of an animal. Moreover, the liquid collecting apparatus includes a first flow path and a second flow path having a given length. Accordingly, the flow path with a given length set in advance and thus a known volume allows collection of a given amount volume of blood without measuring a length and an amount of blood using a volume measuring device. Accordingly, no need of the measuring device allows reduction in size of the liquid collecting apparatus. Consequently, the liquid collecting apparatus can be installed adjacent to the animal to achieve reduction in dead volume. Moreover, blood is flown to a fourth flow path branched with a connecting terminal, and is also flown to the second flow path branched with a connecting terminal.
