What this trial studies

This observational study aims to assess the effects of Haglund syndrome on ankle range of motion (ROM) and postural stability. It will involve fifty participants, including twenty-five patients diagnosed with symptomatic Haglund syndrome and twenty-five healthy volunteers matched for age, sex, and body mass index. The study will utilize the Biodex balance system to evaluate postural stability and an Electrogoniometer to measure ankle plantarflexion and dorsiflexion ROM. Participants will be aged between 25 and 56 years with a BMI of 18.5 to 24.9.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 25-56 with a diagnosis of Haglund syndrome and a BMI between 18.5 and 24.9.

Not a fit: Patients with other musculoskeletal disorders or cognitive and visual impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of the relationship between Haglund syndrome and ankle mobility, potentially leading to improved management strategies for affected patients.

How similar studies have performed: While there may be limited studies specifically on Haglund syndrome, similar assessments of ankle mobility and stability have shown promising results in related conditions.
