Assessment of strength, flexibility, and running mechanics in men with iliotibial band syndrome.

Study Design: Cross-sectional laboratory study.

Objectives: To assess differences in hip strength, iliotibial band length, and hip and knee mechanics during running between male runners with iliotibial band syndrome (ITBS) and healthy controls.

Background: Flexibility, strength, and running mechanics are commonly assessed in patients with ITBS.

Do thigh circumference and mass changes alter knee biomechanics during walking?

Obese adults walk with different biomechanics compared to healthy weight adults. Previous studies have focused on knee biomechanics because they are associated with development and progression of osteoarthritis. Changes in thigh mass and circumference that occur as body weight increases may influence gait.

Test-retest reliability of knee biomechanics during stop jump landings.

Studies that seek to determine the effects of an intervention on knee biomechanics during landing from a jump implicitly assume that the variables of interest are reliable both within and between data collection sessions. Currently, such reliability data are not available for a stop jump. Standard three-dimensional motion analysis was used to determine sagittal and frontal plane peak angles and moments and peak vertical ground reaction force within and between sessions for a stop jump.
