Women are more prone to anterior cruciate ligament (ACL) injury during cutting sports than men. The purpose of this study was to examine knee kinematic and ground reaction forces (GRF) differences between genders during cutting. Male and female athletes performed cutting trials while force platform and video data were recorded (180 Hz). Differences (p < .(More)
Accurate ability to diagnose lumbar spine clinical instability is controversial for numerous reasons, including inaccuracy and limitations in capabilities of radiographic findings, poor reliability and validity of clinical special tests, and poor correlation between spinal motion and severity of symptoms. It has been suggested that common subjective and(More)
BACKGROUND The Shoulder Pain and Disability Index (SPADI) is designed to detect changes in shoulder pain and disability after a one-week interval. With the new Medicare guideline, the SPADI may have to be employed for time frames of less than one week. PURPOSE To determine if the SPADI or its subscales could detect immediate changes in pain and function(More)
Thoracic outlet syndrome (TOS) is a frequently overlooked peripheral nerve compression or tension event that creates difficulties for the clinician regarding diagnosis and management. Investigators have categorized this condition as vascular versus neurogenic, where vascular TOS can be subcategorized as either arterial or venous and neurogenic TOS can(More)
STUDY DESIGN A 2 (group) × 2 (abdominal contraction) × 2 (reach activity) crossover mixed design with repeated measures for contraction and activity examined the effects of a loaded (4.6 kg) forward-reach activity and abdominal drawing-in maneuver (ADIM) on transversus abdominis (TrA) contraction in subjects with nonspecific low back pain (NSLBP) history(More)
BACKGROUND Decreased intervertebral disc height can result in diminished load carrying capacity of the spinal segment. Clinical means of assessing postures able to rehydrate the discs were investigated. OBJECTIVE The purposes of this study were 3-fold: (1) to determine if our test protocol using a commercially available stadiometer demonstrated findings(More)
Workers lose height during the day. Flexion-based exercises and body positions are commonly prescribed to unload the spine and prevent back pain. Lumbar extension positions have been researched and result in an increase in spine height. End-range lumbar extension postures increase spine height to a greater extent than mid-range lumbar extension postures,(More)
Chronic pelvic pain is defined as the presence of pain in the pelvic girdle region for over a 6-month period and can arise from the gynecologic, urologic, gastrointestinal, and musculoskeletal systems. As 15% of women experience pelvic pain at some time in their lives with yearly direct medical costs estimated at $2.8 billion, effective evaluation and(More)
STUDY DESIGN A descriptive cadaveric study incorporating a novel nerve root marking technique. OBJECTIVES To describe the displacement and strain of the lumbosacral nerve roots in the lateral recess during straight leg raise (SLR) without disrupting the foraminal ligaments. SUMMARY OF BACKGROUND DATA Previous studies document 2 to 8 mm of lumbosacral(More)
STUDY DESIGN An inferential cadaveric study. OBJECTIVES To compare the displacement and strain of the lumbosacral nerve roots during different conditions of straight leg raise (SLR) with intact foraminal ligaments. SUMMARY OF BACKGROUND DATA Clinicians use sensitizing movements such as dorsiflexion during neurodynamic testing, assuming that these(More)
