To identify if lower extremity malalignments were associated with increased propensity of a history of anterior cruciate ligament (ACL) ruptures in males and females using a case control design. Twenty subjects (10 males, 10 females) had a history of ACL injury and twenty (10 males, 10 females) had no history of ACL injury. Subjects were assessed for navicular drop, quadriceps angle, pelvic til...

BACKGROUND Lower extremity stiffness is thought to be an important factor in musculoskeletal performance. However, too little or too much stiffness is believed to increase the risk of musculoskeletal injury. PURPOSE To provide a current update of the lower extremity stiffness literature as it pertains to both performance and injury. SUMMARY It appears that increased stiffness is beneficial ...

BACKGROUND Neuromuscular alterations are common following lower extremity joint injury and often lead to decreased function and disability. These neuromuscular alterations manifest in inhibition or abnormal facilitation of the uninjured musculature surrounding an injured joint. Unfortunately, these neural alterations are poorly understood, which may affect clinical recognition and treatment of ...

BACKGROUND Females with history of anterior cruciate ligament (ACL) injury and subsequent ligament reconstruction are at high risk for future ACL injury. Fatigue may influence the increased risk of future injury in females by altering lower extremity biomechanics and postural control. HYPOTHESIS Fatigue will promote lower extremity biomechanics and postural control deficits associated with AC...

Unilateral musculoskeletal below-knee injuries occur with great frequency. Patients who cannot bear weight on an injured limb usually mobilize themselves with standard crutches. When the patient also has an upper limb injury, however, mobilization might be impossible, and can result in a lengthy in-patient stay. A randomized control trial was conducted on 80 patients to share our experience wit...
