Assessing Lateral Stability of the Hip and Pelvis

/
Adequate function of the hip abductor mechanism has been shown to be integral to ideal lower limb function and musculoskeletal health. Clinical assessment of hip abductor muscle function may include observational assessment of postural habits, muscle bulk, and of the ability to control optimal frontal plane femoropelvic alignment during a variety of single leg tasks. Strength testing using a hand held dynamometer is perhaps our most robust clinical assessment tool but should not be considered a ‘gold standard’ in the assessment of abductor muscle function. Evidence from magnetic resonance imaging (MRI), and electromyography (EMG) studies provides a deeper understanding of specific deficits that occur within the abductor synergy. The assessment of abductor function should not be based on a single test, but a battery of tests. The findings should be interpreted together rather than independently, and in the context of a thorough understanding of function of the lateral stability mechanism. Manner and comprehensiveness of abductor assessment will have important implications for management and particularly therapeutic exercise.

Gluteal Tendinopathy: A Review Of Mechanisms, Assessment and Management

/
Tendinopathy of the gluteus medius and gluteus minimus tendons is now recognized as a primary local source of lateral hip pain. The condition mostly occurs in mid-life both in athletes and in subjects who do not regularly exercise. Females are afflicted more than males. This condition interferes with sleep (side lying) and common weight-bearing tasks, which makes it a debilitating musculoskeletal condition with a significant impact. Mechanical loading drives the biological processes within a tendon and determines its structural form and load-bearing capacity. The combination of excessive compression and high tensile loads within tendons are thought to be most damaging. The available evidence suggests that joint position (particularly excessive hip adduction), together with muscle and bone elements, are key factors in gluteal tendinopathy. These factors provide a basis for a clinical reasoning process in the assessment and management of a patient presenting with localized lateral hip pain from gluteal tendinopathy. Currently, there is a lack of consensus as to which clinical examination tests provide best diagnostic utility. On the basis of the few diagnostic utility studies and the current understanding of the pathomechanics of gluteal tendinopathy, we propose that a battery of clinical tests utilizing a combination of provocative compressive and tensile loads is currently best practice in its assessment. Management of this condition commonly involves corticosteroid injection, exercise or shock wave therapy, with surgery reserved for recalcitrant cases. There is a dearth of evidence for any treatments, so the approach we recommend involves managing the load on the tendons through exercise and education on the underlying pathomechanics.
