Passive hip adduction flexibility impairment measured with the modified Ober test predicts chronicity of iliotibial band syndrome: a cross-sectional pilot study (pubmed.ncbi.nlm.nih.gov)

• Modified Ober test used to measure hip adduction flexibility.
• Impaired flexibility associated with increased ITBS chronicity.
• Pilot study with cross-sectional design.

"This cross-sectional pilot study investigated whether passive hip adduction flexibility, measured with the modified Ober test, can predict the chronicity of iliotibial band syndrome (ITBS). Findings suggest that impaired flexibility may be a risk factor for persistent symptoms."
