Abstract

PROBLEM TO BE SOLVED: To provide a method for determining a recover step of a patient with cerebrovascular disorder even when a doctor, physical therapist, and occupational therapist are absent.SOLUTION: Motion of a healthy person is observed by a Microsoft Kinect (R), and at the time, a feature point of the healthy person is determined based on an observation image. A three-dimensional coordinate of the feature point is determined by the Microsoft Kinect, and the coordinate is compared with a three-dimensional coordinate of a patient with cerebrovascular disorder, for statistical processing of a coincidence rate. Therefore, even when a doctor, physical therapist, and occupational therapist are absent, determination of a function recover step of the patient with cerebrovascular disorder is possible.

Description

The present invention relates to a method for determining the recovery stage of a cerebrovascular disorder person by image analysis by a doctor, a physical therapist, or an occupational therapist.

There is no method for determining the recovery stage of patients with cerebrovascular disorders using Microsoft Kinect (registered trademark).

The problem to be solved is a proposal of a method for determining the recovery stage of a cerebrovascular disorder person by using observation information of Microsoft Kinect (registered trademark) even in the absence of a doctor, a physical therapist, or an occupational therapist.

Observe the behavior of healthy individuals with Microsoft Kinect (registered trademark). At that time, the feature point of the healthy person is determined from the observed image. The three-dimensional coordinates of the feature points are determined by Microsoft Kinect (registered trademark), and compared with the three-dimensional coordinates of the cerebrovascular disorder person, the matching rate is statistically processed. This makes it possible to determine the stage of functional recovery for persons with cerebrovascular disorders even in the absence of a doctor, physical therapist, or occupational therapist.

The recovery stage of people with cerebrovascular disorders can be determined with a system of about tens of thousands of yen that combines Microsoft Kinect (registered trademark), computer, and monitor. This enables functional recovery assessment in areas where doctors, physical therapists, and occupational therapists are lacking. For example, Japan's rural areas and overseas rehabilitation developed countries.

It is a principle figure which determines the recovery stage of a cerebrovascular disorder person. This is a process for determining the recovery stage of persons with cerebrovascular disorders.

It consists of Microsoft Kinect (registered trademark), computer and monitor.

FIG. 1 is a principle diagram for determining the recovery stage of a cerebrovascular disorder person. As shown in the figure, when the movement of the healthy person presented on the monitor is the same as that of a person with cerebrovascular disorder, measure the 3D coordinates in real time using Microsoft Kinect (registered trademark) and compare the feature points Thus, the direction of approaching the healthy person is taught by voice and screen display, and the person with cerebrovascular disorder strives to approach the movement of the healthy person as much as possible. The recovery stage is determined by preparing a plurality of teaching operations.
The multiple actions to determine the recovery stage are the 12 items used in the Brunnstrom test and Satoshi Ueda 12-step hemiplegia grade overall judgment, which are used as an index for doctors, physical therapists, and occupational therapists to determine the recovery stage of cerebrovascular disorders. Using the evaluation operation, the recovery stage is determined by the completeness of each operation.
The evaluation operations for the 12 items are as follows.
(1) In the supine position, extend the affected hand to the waist on the opposite side.
(2) Take the tip of the affected hand from the waist on the healthy side to the ear on the affected side (3) Place the hand behind the waist (4) Extend the elbow and raise the upper limb forward horizontally (5) Elbow 90 ° Forearm pronation in flexion position (6) Elbow 90 ° forearm pronation movement in flexion position (7) Raise the elbow and raise the upper limb horizontally (8) Extend the elbow and move the upper limb forward (9) Forearm pronation in elbow extension position (10) Forearm pronation in elbow extension position (11) Raise hand from shoulder to head as soon as possible (12) Move arm as soon as possible Raise horizontally
* (2) to (12) are all performed in a sitting position.
The determination process of the cerebrovascular disorder person based on the completeness of each operation is shown in FIG.

In order to determine the recovery stage of patients with cerebrovascular disorders in the medical field, advanced techniques of rehabilitation professionals such as doctors, physical therapists, and occupational therapists are necessary. The technology for determining the recovery stage of patients with cerebrovascular disorders based on the observation information of Microsoft Kinect (registered trademark) has high potential in areas where there is a lack of rehabilitation professionals. Also, by using observation information of Microsoft Kinect (registered trademark), highly reproducible evaluation becomes possible, which is useful for improving medical quality and efficiency.
