OBJECTIVE To determine the extent to which select lower extremity alignment characteristics of the pelvis, hip, knee, and foot are related to the Q angle. DESIGN Descriptive cohort study design. SETTING Applied Neuromechanics Research Laboratory. PARTICIPANTS Two hundred eighteen participants (102 males, 116 females). ASSESSMENT OF RISK FACTORS Eight clinical measures of static alignmen...

Children with crouch gait frequently walk with improved knee extension during the terminal swing and stance phases following hamstrings lengthening surgery; however, the mechanisms responsible for these improvements are unclear. This study tested the hypothesis that surgical lengthening enables the hamstrings of persons with cerebral palsy to operate at longer muscle-tendon lengths or lengthen ...

The iliotibialis lateralis pars postacetabularis (ILPO) is the largest muscle in the hindlimb of the guinea fowl and is thought to play an important role during the stance phase of running, both absorbing and producing work. Using sonomicrometry and electromyography, we examined whether the ILPO experiences differential strain between proximal, central and distal portions of the posterior fasci...

Purpose: Changes in lower extremity alignment in individuals with abnormality of this segments are unclear. The present study aimed to compare lower extremity alignment in subjects with genu valgum and genu varum deformities and healthy subjects  in order to understand the lower extremity alignment changes in this group.  Methods: This was a causal-comparative study. The sample comprised 120 m...

Peripheral nerve injuries of the lower extremity (LE) are frequently encountered in orthopaedic practice. They can be traumatic or iatrogenic. Proper and timely diagnosis and treatment are the keys to optimizing outcomes. This paper reviews and discusses the basic anatomy and physiology of nerve injury and the current literature on the incidence, pathogenesis, diagnosis, management and outcomes...
