Pelvic Parameters in Males With and Without Ankle Instability

2026年5月14日更新者：Ahmed Korany Abdallah Ahmed

Pelvic Parameters in Male Athletes With and Without Chronic Ankle Instability: A Cross Sectional Study

This study aims to investigate the relationship between pelvic alignment and ankle stability in male athletes with and without a history of ankle sprain.

Chronic ankle instability is a common condition that may affect not only the ankle joint but also the alignment and function of other body segments, including the pelvis. Understanding this relationship may help improve injury prevention and rehabilitation strategies.

Participants will undergo clinical assessments, functional tests, and radiographic evaluation of pelvic parameters to compare findings between injured and non-injured groups.

The objective of this study is to determine whether differences in pelvic sagittal parameters are associated with ankle instability in male athletes.

詳細な説明

This cross-sectional case-control study aims to investigate the relationship between chronic ankle instability and pelvic sagittal alignment in male athletes. Chronic ankle instability may lead to alterations in lower limb biomechanics, postural control, and proximal body alignment, including pelvic positioning.

Participants will be divided into two groups: athletes with chronic ankle instability and healthy athletes without a history of ankle instability. All participants will undergo clinical evaluation, functional assessment, and radiographic measurement of pelvic sagittal parameters.

Clinical assessment will include evaluation of ankle instability severity, pain intensity, and dynamic balance performance using validated assessment tools. Pelvic alignment parameters will be assessed radiographically to identify potential biomechanical differences between groups.

The findings of this study may contribute to a better understanding of the relationship between chronic ankle instability and proximal biomechanical adaptations, which may improve rehabilitation and injury prevention strategies in athletes.

調査対象母集団

The study will include male competitive football players aged 18 to 35 years. Cases will be defined as players with chronic ankle instability following a history of lateral ankle sprain, while controls will be healthy players without a history of ankle sprain or chronic ankle instability. Participants will be recruited from sports clubs and physiotherapy outpatient departments.

説明

Inclusion Criteria:

Male football players aged between 18 and 35 years (Herzog et al., 2019; Jiang et al., 2022).
A documented history of lateral ankle sprain (LAS) for at least 12 months before the study, with the initial injury resulting in a minimum of one day of weight-bearing restriction.
Self-reported episodes of ankle "giving way" occurring at least twice within the 6-12 months preceding enrollment.
The most recent injury must have occurred more than 3 months before study enrollment.
A perceived sense of the injured ankle being chronically weaker and/or less functional than the contralateral side before the first LAS episode.
A Cumberland Ankle Instability Tool (CAIT) score of less than 24 indicates chronic ankle instability.
For group B: participants with no previous history of ankle sprain.

Exclusion Criteria:

Bilateral LAS (Tahoon et al., 2022).
Previous injury, fracture, or surgical intervention involving the spine, pelvis, or lower extremity.
History of low back pain requiring medical or surgical intervention.
Engagement in supervised or unsupervised ankle rehabilitation within one month before the study.
Any LAS occurring within three months before participation.
Leg length discrepancy exceeding 0.5 cm.

Group A: Male athletes with a history of ankle sprain and chronic ankle instability. Group A Male Athletes With Chronic Ankle Instability Male competitive football players aged 18 to 35 years with a history of unilateral lateral ankle sprain and symptoms consistent with chronic ankle instability. Participants in this group will report recurrent episodes of ankle "giving way," perceived ankle weakness and/or reduced ankle function, and a Cumberland Ankle Instability Tool (CAIT) score of less than 24. The most recent ankle sprain must have occurred more than 3 months before enrollment.
Group B: Male athletes without a history of ankle sprain or chronic ankle instability. Group B Healthy Male Athletes Male competitive football players aged 18 to 35 years with no previous history of lateral ankle sprain, chronic ankle instability, or lower limb musculoskeletal injury within the previous 12 months. Participants in this group will be matched to the chronic ankle instability group according to age, playing level, and training exposure.
