Abstract
Symptomatic external snapping hip is a painful condition, where pain in the trochantor region and limitations of daily activity dominate clinical findings. The aetiology of symptomatic external snapping hip is elusive, but previous studies have suggested that weakness of the hip abductors and an altered walking pattern may play a role in the development of symptomatic external snapping hip.

The aims of this study were to:

1: Compare the walking pattern and muscular activity of the hip muscles between subjects with symptomatic external snapping hip and healthy subjects.

2: To investigate whether eccentric hip abduction strength is decreased in patients with external snapping
hip compared with healthy matched controls, and to examine isometric hip abduction, adduction, extension,
flexion, internal rotation, and external rotation in patients with external snapping hip and matched controls.
