Brief Summary

This research aims to complement existing podiatric studies by providing information on the relationship between ligamentous hyperlaxity, a benign condition more frequently found in the pediatric population, and ankle range of motion in child basketball players aged 8-15. Furthermore, this hyperlaxity will allow us to correlate it with the most frequent type of injury experienced by the participants and assess whether future research could develop a prevention plan for this population and extrapolate it to more professional categories.

Conditions

Children Basketball Players; Ligamentous Hypermobility of the Toe

Keywords

ankle; octobalance; stargazing test; dorsiflexion; hypermobility; range of movement; dynamic balance; movement quality

Outcome Measures

Primary Outcomes (4)

• "Ankle Test" with Leg Motion® (Check Your Motion®, Albacete, Spain)

  Validated to numerically quantify ankle dorsiflexion, it provides very low levels of interobserver bias (ICC values ranged from 0.96 to 0.98)

  Baseline

• Easy Angle digital inclinometer

  It was used to obtain data on the inclination of the tibia relative to the ground, measured from the tibial tuberosity or 15 cm below it. It was also used to complete the Beighton scale in the ranges of finger, elbow, and knee hyperextension because it can function as a simple goniometer.

  Baseline

• "Lower Body Test" at Octobalance (Check Your Motion®, Albacete, Spain)

  Considered innovative for the information it provides to prevent injuries, this patented system allows us to see limb imbalances, joint restrictions such as those in the ankle, and evaluate the quality of movement during dynamic balance.

  Baseline

• Beighton Scale

  The most widely used tool for measuring generalized hypermobility in the healthcare field. Parameters used in this population have been measured using units from 0 to 9.

  Baseline

Study Arms (2)

Hypermobile group (H+)

Children playing basketball with ligamentous hyperlaxity

Non-hypermobile group (H-)

Children who play basketball and do not suffer from ligamentous hyperlaxity

Eligibility Criteria

• Age: 8 Years - 15 Years
• Sex: male
• Healthy Volunteers: Yes
• Age Groups: Child (0-17)
• Sampling Method: Non-Probability Sample

Study Population

The study population will consist of male basketball players from the Puerto de Sagunto Basketball Club. The subjects who will participate in the study will be those who volunteer and meet the established selection criteria. The sample will include basketball players from the following age categories: U12 (8-10 years), U14 (10-12 years), and U16 (13-15 years).

You may qualify if:

• Subjects within the age range specified in the study.
• Signed and fully completed parental consent form.
• Participation in basketball as a sport twice a week, not including school physical education, or a total of 3 hours per week.

You may not qualify if:

• Subjects with injuries or any musculoskeletal impairment relevant to the measurement of the parameters to be evaluated.
• Any temporary illness that prevents the participant from being in full physical condition.
• Disorders related to loss of balance due to vestibular, cognitive, or cerebellar causes.
• Performance of a warm-up outside of the established protocol.
