Abstract Background: Haglund's syndrome is a common painful musculoskeletal condition in adults and increases health prob-lem, causing functional disability in large populations. Aim of Study: The aim of this cross-sectional correlational study was to investigate relationship between pain and ankle mobility in Haglund syndrome. Subjects and Methods: Fourteen subjects with Haglund syndrome were included in this study. Their mean ± SD of age, weight, height, and BMI were 46.29±10.00 years, 68.43±10.66Kg, 170 .64±9.23cm, 23 .36±1.49kg/m2 respective-ly. They were referred by orthopedic surgeons with a diagnosis of Haglund's syndrome. All subjects were assessed for ankle dorsiflexion and plan-tar flexion range of motion using digital goniometer. In addi-tion, subjects in the study were assessed for pain intensity using the Visual Analog Scale (Vas). Correlation between variables in the study group was performed using Pearson's correlation coefficient. Results: There was negative moderate significant correla-tion between pain and ankle dorsi flexion (r=-0.532, pl).05), while positive moderate non significant correlation with ankle planter flexion. Conclusion: Haglund syndrome has a negative effect on ankle dorsiflexion but doesn't affect plantar flexion. Patients with Haglund syndrome experience more affection in pain.
