The importance of function of the central core of the body for stabilisation and force generation in all sports activities is being increasingly recognised. 'Core stability' is seen as being pivotal for efficient biomechanical function to maximise force generation and minimise joint loads in all types of activities ranging from running to throwing. However,(More)
Proper on-the-field management of an athlete with a suspected spinal injury has long been a topic of discussion among certified athletic trainers and other allied healthcare professionals. Because each group has its expertise in a particular area, the question of correct technique or appropriate procedure has been the subject of much debate. Recognizing a(More)
Knee extension is always performed with coordinated contractions of multiple quadriceps muscle components; however, how the load is shared among them under normal and pathological conditions is unclear. We hypothesized that: the absolute moment generated by each quadriceps component increases with the total knee extension moment; the relative contribution(More)
There is little information available regarding management of apraxic gait. We present a 61-year-old man with a five-year history of right-sided cerebrovascular accident, apraxic gait, difficulty in walking, and frequent falls. A CT head scan revealed moderate cerebral atrophy, a small lacunar infarction. The patient was unable to initiate walking, was bed(More)
Patellofemoral pain is a common knee disorder with a multi-factorial etiology related to abnormal patellar tracking. Our hypothesis was that the pattern of three-dimensional rotation and translation of the patella induced by selective activation of individual quadriceps components would differ between subjects with patellofemoral pain and healthy subjects.(More)
BACKGROUND Compared to standing posture, sitting decreases lumbar lordosis, increases low back muscle activity, disc pressure, and pressure on the ischium, which are associated with occupational LBP. A sitting device that reduces spinal load and low back muscle activities may help increase sitting comfort and reduce LBP risk. The objective of this study is(More)
The goal of this study was to use an offaxis robotic elliptical trainer to improve off-axis neuromuscular control in people with knee injuries. Thirteen individuals with knee injuries participated in the study. Among them, 8 individuals participated in 18 sessions of pivoting offaxis intensity-adjustable neuromuscular control training (POINT) (3(More)
Analysis of shoulder dysfunction in throwing and overhead athletes can no longer be restricted to evaluation of the glenohumeral joint alone. The isolated shoulder is incapable of generating the force necessary to hurl a baseball at velocities of 90-100 miles per hour or serve a tennis ball in excess of 120 miles per hour. The purpose of this paper is to(More)

The idea that beliefs may be stake-sensitive is explored. This is the idea that the strength with which a single, persistent belief is held may vary and depend upon what the believer takes to be at stake. The stakes in question are tied to the truth of the belief—not, as in Pascal's wager and other cases, to the belief's presence. Categorical beliefs and(More)
Dear Fellowship Applicant, Thank you for your interest in our Spine and Sports Fellowship at the Rehabilitation Institute of Chicago and Northwestern Feinberg School of Medicine. July 2015 will mark the start of the 23rd year of this program. The fellowship is twelve months in duration and includes clinical, teaching, and research experiences. The(More)
