Embodiment 1

[0037] figure 1 The walking evaluation system 1 in Example 1 of the present invention is shown. exist figure 1 Among them, reference numeral 40 is the foot of the person to be measured, 10 is a pedometer attached to the foot 40 of the person to be measured, and 20 is to receive data Data related to the walking of the person to be measured and perform various The personal computer PC, 35 for estimation and evaluation is a display device such as a monitor of the PC 20 . Such as figure 1 As shown, the foot 40 is preferably the instep of the foot. Please note: The term "foot" used in this manual does not only refer to feet, but also includes ankles, lower legs, etc. Only one pedometer 10 may be attached to one foot (dominant foot) of the subject, but may be attached to both feet. Such as figure 1 As shown in the internal module 11 of the pedometer 10, the pedometer 10 has a measuring device 12 for measuring data related to the walking of the subject. The PC 20 can receive t...

Embodiment 2

[0057] The pedometer 10 may further include an operation unit (operation unit) 16 for performing predetermined operations based on data Data related to walking measured by the measuring device 12 . Examples of the operating unit 16 include a device that performs an operation such as vibration, a device that performs an operation such as buzzer, a device that performs an operation such as emitting light, or a combination of these devices. When the pedometer 10 detects, for example, that the person to be measured is in a state of dragging his feet, based on the data Data related to walking measured by the measuring device 12 (the acceleration ACC measured by the acceleration sensor 13 and the inclination CLI measured by the inclination sensor 14) , can perform actions such as vibration. For the detection, functions such as the above-mentioned landing estimation unit 27 may be embedded in the pedometer 10 in advance. As a result, by attaching the pedometer 10, the subject can ea...

Embodiment 3

[0059] FIG. 6 is a block diagram showing an internal circuit 60 of a computer of the PC 20 that executes a computer program for realizing the present invention of each of the above-described embodiments. As shown in FIG. 6 , CPU 61 , ROM 62 , RAM 63 , image control unit 66 , controller 67 , input control unit 69 , and external interface (I / F) unit 71 are connected to bus 72 . In FIG. 6, the above-mentioned computer program of the present invention is recorded on a recording medium (including detachable recording medium) such as a ROM 62, a disk (disc) 68a, or a CD-ROM 68n. In the magnetic disk 68a, averages of walking states such as strides by gender, age, and age group used by the evaluation unit 30, comments corresponding to Levels, and the like can be recorded in advance. The computer program of the present invention is loaded into RAM 63 from ROM 62 via bus 72 , or from a recording medium such as magnetic disk 68 a or CD-ROM 68 n via controller 67 via bus 72 . The input c...

Abstract

To provide a compact and inexpensive gait assessment system, including a basograph, which can be readily handled by, for example, trainers, and can eliminate the necessity to select any specialized measurement space to detect foot movement during walking. A basograph (10) is equipped with a measuring instrument (12), including, for example, an acceleration sensor (13), for measuring data related to gait of a subject, and a PC (20) receives the data via a USB interface or suchlike, so that an estimating section (22) estimates the gait status of the subject based on the received data. The estimating section (22) includes at least one of the following elements for performing estimation based on predetermined-direction acceleration ACC of the subject's foot (40) at each sampling time: a push-off estimating part (23) for estimating the intensity of the subject's push-off; a tempo estimating part (24) for estimating gait tempo; an elevation estimating part (25) for estimating foot elevation; and a stride estimating part (26). An assessing section (30) assesses the gait status of the subject based on the estimation of the estimating section (22), and a presentation section (31) presents the assessment result by the assessing section (30) in a predetermined form.

Description

technical field [0001] The present invention relates to a walking evaluation system, etc., comprising: a pedometer having a measuring device for measuring data related to a subject's walking; data. Background technique [0002] The muscles used in walking are: quadriceps, etc., used for lifting the foot, etc., tibialis anterior muscle, etc., used for supporting the ground and lifting the toes, etc., and kicking and heel lifting, etc. Use the lower body triceps, etc. When these muscles weaken with aging, they become shuffled feet, creating the possibility of falling. Conventionally, in order to prevent falls of the elderly or those with walking disabilities, various instruction has been given by trainers such as physical therapists and occupational therapists in fall prevention classes for the elderly and the like. However, since the instruction method differs depending on the instructor, in order to create an accurate instruction training program, it is necessary to quant...
