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.
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.

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.
Time frame: 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.
