BACKGROUND The evaluation of foot posture in a clinical setting is useful to screen for potential injury, however disagreement remains as to which method has the greatest clinical utility. An inexpensive and widely available imaging system, the Microsoft Kinect™, may possess the characteristics to objectively evaluate static foot posture in a clinical(More)
The purpose of this study was to elucidate the effect of normal fluctuating [non-monophasic oral contraceptive pill (MOCP) users] and low, consistent (MOCP users) endogenous plasma estrogen levels on the strain behavior of the Achilles tendon in vivo. Twenty women (age 28.0 +/- 4.2 yr, height 1.67 +/- 0.07 m, mass 61.6 +/- 6.8 kg) who had been using the(More)
New research has changed our perception and management of common injuries. Magnetic resonance imaging and arthroscopy of the hip have shown that labral injuries, chondral injuries, rim lesions, synovitis and tears of the ligament teres are common causes of hip, groin and low-back pain. Hip arthroscopy is used both as a diagnostic and therapeutic tool; it(More)
Excessive foot pronation has been associated with injuries of the lower extremity. No research has investigated the effect of enhancing plantar sensory feedback on foot pronation. The aim of this study was to determine whether a shoe with enhanced plantar sensory feedback reduces midfoot pronation. Midfoot kinematics and electromyography of the peroneus(More)
BACKGROUND The relationship between the phases of the menstrual cycle and injury risk remains unclear. Neuromuscular function may be compromised during menstruation, which could result in reduced cyclicality of movement patterns. We hypothesize that mediolateral (varus/valgus) knee acceleration during running gait will possess increased variability during(More)
Estrogen receptors in skeletal muscle suggest a tissue-based mechanism for influencing neuromuscular control. This has important physiological implications for both eumenorrheic women with fluctuating estrogen levels and those with constant and attenuated estrogen levels, i.e., women using the monophasic oral contraceptive pill (MOCP). This study examined(More)
BACKGROUND Footwear remains a prime candidate for the prevention and rehabilitation of Achilles tendinopathy because it is thought to decrease tension in the tendon through elevation of the heel. However, evidence for this effect is equivocal. PURPOSE This study used an acoustic transmission technique to investigate the effect of running shoes on Achilles(More)
Severe hyperglycemia and insulin resistance due to antiinsulin receptor antibodies developed over a period of 3 months in a 50-yr-old insulin-requiring diabetic patient. The hyperglycemia resulted from overproduction of glucose due to excessive rates of glycogenolysis and gluconeogenesis rather than decreased glucose utilization. Treatment with(More)
This case study reports the kinematic effect of 2 different cricket shoes on a fast bowler who reports a history of posterior ankle joint impingement. The participant bowled 6 trials in 2 pairs of cricket shoes. The 3-dimensional kinematics of the joints of the front leg was quantified during stance phase of the delivery stride. Wearing the high-cut shoe(More)
