About this study
Official title: Recurrent Neural Networks for Windlass Mechanism Subphase Recognition and Anthropometric Angles Monitoring
This study measures the medial longitudinal arch angle and the metatarsophalangeal angle during the gait cycle in 35 healthy participants using speed cameras and reflective markers placed on anthropometric points.
Read the detailed description
The medial longitudinal arch angle comprises the calcaneus, navicular tuberosity, and the head of the 1st metatarsal, while the metatarsophalangeal angle comprises the head of the 1st metatarsal and the proximal interphalangeal joint of the toe. These measurements provide valuable information on the stress of the plantar fascia.

What is being measured
The primary outcome is the main question the study is designed to answer.
Metatarsophalangeal Joint Angle
This angle comprises the supplementary angle formed by the first metatarsal head, posterior calcaneus, and proximal interphalangeal. The angle is measured using a marker-based motion capture system with blue markers placed on these points and recorded with cameras operating at 60 frames per second. A centroid-based landmark detection algorithm determines the centroid coordinates and applies trigonometric functions to each frame to calculate the angle in degrees with a precision of two decimal places.
Measured: Baseline
Medial Longitudinal Arch Angle
This angle is defined by the anthropometric landmarks of the calcaneus, the navicular tuberosity, and the head of the first metatarsal. The angle is measured using a marker-based motion capture system with blue markers placed on these points and recorded with cameras operating at 60 frames per second. A centroid-based landmark detection algorithm determines the centroid coordinates and applies trigonometric functions to each frame to calculate the angle in degrees with a precision of two decimal places.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study measures the medial longitudinal arch angle and the metatarsophalangeal angle during the gait cycle in 35 healthy participants using speed cameras and reflective markers placed on anthropometric points.
Detailed description
The medial longitudinal arch angle comprises the calcaneus, navicular tuberosity, and the head of the 1st metatarsal, while the metatarsophalangeal angle comprises the head of the 1st metatarsal and the proximal interphalangeal joint of the toe. These measurements provide valuable information on the stress of the plantar fascia.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Mexico. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Metatarsophalangeal Joint Angle (time frame: Baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
