It is dealt with detection of the walking path, the one leg walking detection system, and the one leg walking

摘要

PPROBLEM TO BE SOLVED: To precisely detect only the potential waveform of one-leg walking movement. PSOLUTION: This one-leg walking detection system is provided with a walking passage 14, a probe 11 and a potential sensor 12. The walking passage 14 is provided with a first walking passage 14A for making a patient P walk with one of the legs being the object to be detected and a second walking passage 14B for making the patient P walk with the other leg being not the object to be detected, side by side. Differentiated charging characteristics are provided for the first and second walking passages 14A and 14B so that a human body potential by dissociative charging occurring when the bottom surface of the leg being the object to be detected contacts or is separated from the surface of the first walking passage 14A may be more than that occurring when the bottom surface of the leg being not the object to be detected contacts or is separated from the surface of the second walking passage. The probe 11 senses the potential change of the human body caused by separation charge occurring when the patient P walks on the walking passage 14. The potential sensor 12 obtains the waveform signal of the potential change from a signal sensed by the probe 11. PCOPYRIGHT: (C)2004,JPO&NCIPI
