Measurement of Foot Orthotics Based on Foot Molding Using Impression Material and Effect Verification Through Gait Analysis

UMIN ID: UMIN000054596

Registered date:08/06/2024

Basic Information

• Recruitment status: Pending
• Health condition(s) or Problem(s) studied: foot disorders
• Date of first enrollment: 2024/07/01
• Target sample size: 20
• Countries of recruitment: Japan
• Study type: Interventional

Intervention(s)

In this study, the factors and levels considered to influence proprioception through orthotic design are as follows: 1) molding procedure (from the front, from the back), 2) years of experience (less than 3 years, 10 years or more), 3) midfoot compression (light, strong), 4) presence of rearfoot post (yes, no), 5) shell material (soft, hard), and 6) rearfoot control (neutral, valgus). Using these factors, an experimental design employing an orthogonal array will be conducted with one participant to identify the factors with significant main effects and interaction effects. After selecting the factors, a single-subject design using the AB method will be carried out with a small number of cases to scientifically evaluate the effects of these factors.
Non-orthotic condition
