Passive hip adduction flexibility impairment measured with the modified Ober test predicts chronicity of iliotibial band syndrome: a cross-sectional pilot study (tandfonline.com)

• Impaired hip adduction predicts ITBS chronicity
• Modified Ober test as prognostic tool
• Pilot study with 30 participants

"A cross-sectional pilot study investigated the association between passive hip adduction flexibility (using the modified Ober test) and chronicity of iliotibial band syndrome (ITBS). Findings indicate that reduced flexibility significantly correlates with longer symptom duration, suggesting hip adduction measurement may serve as a prognostic marker for chronic ITBS."
