Objectives

Narrative objectives1

This study aims to clarify the following within the research period, using the healthy walking database provided for research, targeting healthy people and stroke hemiplegia.

1) Develop an index (GDI: Gait_Degree_Index) that can relatively evaluate the angle of "hip joint", "knee joint", "foot joint" and "lower leg" at the characteristic point of each walking cycle.

2) Verify the reliability and validity of GDI among healthy people.

3) Verify the reliability and validity of GDI in stroke.

4) Build a system that can easily measure and calculate GDI in clinical practice.

Using GDI, quantitatively evaluate the walking pattern of hemiplegic people and establish a way to objectively detect walking abnormalities. This makes it easier to grasp the problems of the subject, makes it possible to plan an accurate and individualized treatment plan, and it is possible to contribute to the improvement of the subject's walking.

Interventions/Control_1

VICON's three-dimensional motion analysis system was used for measurement. The measurement time is expected to take about 2 hours. In addition, in order to easily calculate GDI clinically, we plan to use "Open cap" developed by Stanford University (https://www.opencap.ai). By using this, you can easily measure the joint angle and walking speed in the clinical field without using a large-scale device, and it will be possible to calculate GDI. However, since the accuracy of the Open cap has not been verified, three-dimensional motion analysis and Open cap are measured at the same time, and the walking speed and joint angle are extracted respectively to verify the accuracy of the Open cap.

Key inclusion criteria

(1) GDI calculation

Utilize all the data for 298 people held by the Walking Database Research Subcommittee of the Biomechanistry Society. The calculation basis is that the amount of information for 298 people is sufficient as the number of samples in which the extracted data can be normally distributed.

(2) Three-dimensional motion analysis and Open cap measurement at Hokkaido University of Science

We believe that the number of people in three-dimensional motion analysis and Open cap measurement in healthy and stroke hemiplegia is about N=5 respectively. This is intended to verify whether the measurement data in the Open cap is different from the data in the three-dimensional motion analysis device, and we believe that it is sufficient for accuracy verification. The research subjects will be publicly recruited, and they will be posted on the website as an information disclosure document to Sapporo Aso Neurosurgery Hospital.

(3) Open cap measurement at Sapporo Aso Neurosurgery Hospital

I think that about N = 5 is also reasonable for measurement at Sapporo Aso Neurosurgery Hospital. As for the N number, the purpose is to verify whether it is possible to measure easily in clinical practice, and since the accuracy verification of the Open cap is carried out in advance by three-dimensional motion analysis and Open cap measurement at Hokkaido University of Science, the N number is reasonable. I'm thinking. The research subjects will be publicly recruited, and they will be posted on the website as an information disclosure document to Sapporo Aso Neurosurgery Hospital.
