Tokyo, Sept. 4 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000062813) titled 'A study on whether stick-figure picture training improves physical therapy students' ability to estimate joint angles from gait videos' on Sept. 3.

Study Type: Interventional

Study Design: Basic Design - Parallel Randomization - Randomized Blinding - Open -no one is blinded Control - No treatment

Primary Sponsor: Institute - Tohoku Bunka Gakuen University

Condition: Condition - Final-year undergraduate students enrolled in a physical therapy program. Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - This pilot randomized controlled trial aims to evaluate the effects of stick-figure-based perceptual training on the accuracy of observational gait analysis (OGA) in physical therapy students. Specifically, the study examines three research questions: (1) whether stick-figure training improves accuracy of joint angle estimation compared with a control condition; (2) whether learning effects differ between vertical and non-vertical viewing conditions of stick-figure stimuli; and (3) whether training effects transfer to a clinically relevant task involving observation of actual patient gait videos. As a pilot trial, the study also seeks to inform the design of a subsequent confirmatory trial by estimating effect sizes and identifying methodological constraints. Basic objectives2 - Others

Intervention: Interventions/Control_1 - Participants in the training group performed an error-correction stick-figure training program in a single session. The program consisted of 150 trials total: 75 trials under the vertical condition and 75 trials under the non-vertical condition, with 25 trials per joint (hip, knee, ankle) in each condition. In the vertical condition, the basic axis of the stick-figure was always aligned vertically. In the non-vertical condition, the entire stick-figure was rotated by 10-20 degrees while preserving the target joint angle, displacing the basic axis from vertical. For each trial, a stick-figure stimulus was presented on a computer screen and participants estimated the joint angle. Immediately after each response, the correct answer was presented as feedback to facilitate error correction. Stick-figure stimuli were generated at predefined angles ranging from 0 to 40 degrees in 5 degree increments. Training stimuli were designed to be non-overlapping with pre- and post-test stimuli. Interventions/Control_2 - Participants in the control group received no training intervention. They were instructed to rest quietly for the same duration as the training session of the training group. No stick-figure stimuli, joint angle estimation tasks, or feedback were provided during this period. Pre- and post-test assessments were administered using the same procedures and stimuli as the training group, with an equivalent time interval between the two assessments.
