Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This condition is especially common among athletes, even at a youth age, due to repeated loads that can lead to tissue and/or joint damage. The compensations that occur in athletes with an FHL can negatively affect sports performance and start injuries.
Limited ankle dorsiflexion under load is another element that can affect sports performance as well as predisposing to injury. Several studies have investigated its regional interdependence but only a few have hypothesized a correlation between this limitation and FHL.
The aim of this study is to understand a possible correlation between reduced ankle DF and reduced MTF dorsiflexion during loading, so that preventive action can be taken to reduce the risk of injury.
Participants will fill in a cross-check survey to establish if there are any predisposing factors for FHL or ankle DF reduction.
The dorsiflexion lunge test (DLT) will be used to measure ankle dorsiflexion. The Jack Test will be used to measure first toe dorsiflexion under load and the Dorsiflexion Lunge Test will be used to measure ankle DF.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Participant
The participants must be teenage basketball players (12-17 years old).
The exclusion criteria are:
* have suffered in the last 3 months of lower limb musculoskeletal disorders such as pain for more than 7 days (ankle distortion outcomes, leg/foot fractures, plantar fasciopathy, metatarsalgias, etc);
* athletes who have undergone surgery on their lower limb.
Dorsiflexion lunge test
The dorsiflexion lunge test (DLT) will be used to measure ankle dorsiflexion. To perform this test, the participant stands in front of a wall holding the foot of their limb to be measured perpendicularly to it. The other foot is to be kept behind it. The participant is asked to perform a lunge (to dorsiflex the ankle and bring the knee into flexion) until the front knee touches the wall without the heel lifting off the ground. The participant steps away from the wall as much as possible as long as the knee keeps touching the wall. Measurement in centimeters is taken from the heel of the examined leg to the wall.
Jack Test
The Jack Test will be used to measure the first toe dorsiflexion under load. The examiner pulled the proximal phalanx of the hallux to dorsiflexion with his hand until the maximal amount of mobility was reached with the subject standing. The static arm of the goniometer was placed along the first metatarsal longitudinal axis while the free movable arm followed the proximal phalanx of the hallux axes.
