摘要： A wearable gait detection device, a walking ability improvement system and a wearable gait detection system detect manifestation in a brain based on the wearer's gait and preventive measures. A load measurement part measures a load of a sole of the wearer's feet, a foot movement detection part at the shoes detects acceleration and/or angular velocity during feet movement, a centroid position calculation part calculates a centroid position of the feet based on changes in measured load, a movement locus calculation part calculates a movement locus of the feet based on acceleration and/or angular velocity detected by the foot movement detection part, a manifestation recognition part recognizes manifestation in the brain according to a specificity of centroid fluctuation of the feet based on the calculated centroid position and movement locus of the feet, and a sensory output part feeds back a sensation to the wearer based on a recognition result.

摘要： Provided is a walking aid device capable of easily offering walking training by aiding the oscillation of the user's pelvis. The walking aid device comprises a drive part which supports each of at least two or more locations of the user's lumbar region, and applies external force independently to each of the supported locations; a gait recognition unit which recognizes the user's gait; and a control unit which sets the user's ideal walking motion pattern based on a recognition result of the gait recognition unit, and controls the external force applied by the drive part to each of the locations of the lumbar region so that the user's pelvis position within the lumbar region will oscillate to match the walking motion pattern.

摘要： A gait disorder support apparatus and gait disorder support method capable of detecting an onset sign of a gait disorder associated with motor symptoms in advance and performing motion assist are proposed. The onset sign of the gait disorder associated with the motor symptoms of a wearer is detected based on the correlation between a gait cycle and a reduction ratio of the gait cycle as compared to immediately preceding gait; and when the onset sign of the gait disorder is detected, a drive unit is controlled so that the drive unit applies assist power to a knee joint of the wearer; and on the other hand, when the onset sign of the gait disorder is not detected, the drive unit is controlled so that driving torque by the drive unit does not hinder the wearer's gait motion.

摘要： Proposed are a functional improvement evaluation apparatus and a nerve cell culture apparatus of model animals capable of performing feedback control, even to mammalian model animals, based on biosignals in the same manner has humans based on a relatively simple configuration. The present invention comprises a biosignal detection unit which is mounted on a central side above an intended in vivo site of a mammalian model animal and/or a peripheral side below an intended in vivo site of a mammalian model animal, and detects a biosignal resulting from a biological activity of the model animal, a control unit which causes a driving source to generate power according to an intent of the model animal based on the biosignal detected by the biosignal detection unit, and a motion transmission mechanism which is connected to a holding part for holding a foot of each leg of the model animal, and transmits the power of the driving source to the holding part so that the holding part swings at a same or approximate trajectory as a natural walking motion pattern of the model animal, and the control unit controls the power of the driving source based on a swing state of the holding part connected to the motion transmission mechanism.

摘要： A biopotential can be measured with high accuracy without the electrodes coming into direct contact with the skin and without being affected by any motion artifact. The present invention comprises a first lead which detects a biopotential containing noise components, a second lead which is electrically isolated from the first lead and detects noise components, and a differential amplifier circuit which is input with a first signal output from the first lead and a second signal output from the second lead, and which amplifies and outputs a difference between the first signal and the second signal, wherein a value of an input impedance on the second signal side of the differential amplifier circuit is set so that the noise components detected from the second lead will have a frequency that is higher than a frequency spectrum of the biopotential.
