Study of Windlass Mechanism in the Lower Limb Using Inertial Sensors.

Aims: This study aimed to quantify the degrees of movement that occur in the lower limb using a kinematic system after taking two measurements of 45° and 60° of extension at the first metatarsophalangeal joint (1st MTPJ) and to test the validity of this sensor system using radiography.

Methodology: This was a quasi-experimental test-post-test study with a single intervention group (25 subjects). Four inertial sensors were placed on the proximal phalange of the first toe, dorsum of the foot, medial-lateral of the leg (level of tibia), and medial-lateral of the thigh (level of femur).

Fatigue in Children with Pronated Feet After Aerobic Exercises.

Background: Sports have a strong influence on current society. Foot posture has been postulated to be a risk factor for overuse injuries; however, the link between foot posture and injuries is unclear. This study aimed to determine whether children with pronated feet become more fatigued after participating in sports tests than those with normal feet.
