Studies that seek to determine the effects of an intervention on knee biomechanics during landing from a jump implicitly assume that the variables of interest are reliable both within and between data collection sessions. Currently, such reliability data are not available for a stop jump. Standard three-dimensional motion analysis was used to determine(More)
Of 61 consecutive patients undergoing laparoscopic cholecystectomy, 4 (6.25%) developed abdominal wall haematomas. This complication of laparoscopic cholecystectomy may occur more commonly than existing literature suggests, and manifests in the post-operative period (days 2 to 6) by visible bruising, excessive pain or an asymptomatic drop in haematocrit. It(More)
BACKGROUND Medical decision making is based on patient autonomy and informed consent, which is an integral part of medical ethics, risk management and clinical governance. Consent to treatment has been extensively discussed, but the viewpoint of patients is not well represented. A new consent form was introduced by the Department of Health in 2001. AIMS(More)
BACKGROUND Biofeedback has been used in rehabilitation settings for gait retraining. PURPOSE The purpose of this review was to summarize and synthesize the findings of studies involving real-time kinematic, temporospatial, and kinetic biofeedback. The goal was to provide a general overview of the effectiveness of these forms of biofeedback in treating(More)
During time-zone travel, the endogenous melatonin rhythm is often out of phase with the new local time cues. Since endogenous melatonin could act as an endogenous zeitgeber, when its secretory rhythm is out of phase it may hinder adaptation by natural zeitgebers. It is possible that by temporarily suppressing the production of melatonin, by beta-blockers(More)
STUDY DESIGN Randomized controlled trial. OBJECTIVES To determine the effects of instruction to improve frontal plane knee biomechanics during a jump-landing task. BACKGROUND Technique training is a common component of knee injury-prevention programs. In developing programs that minimize time commitment and increase the likelihood of adoption by target(More)
STUDY DESIGN Preassessment and postassessment of treatment intervention. OBJECTIVE To determine the changes in pain and disability secondary to shoe lift intervention for subjects with chronic low back pain (LBP) who have a limb length inequality (LLI). BACKGROUND Previous reports have suggested that LLI may be a cause of LBP Most prior studies of lift(More)
Study Design Controlled laboratory study, within-session design. Background Gait retraining has been proposed as an effective intervention to reduce impact loading in runners at risk of stress fractures. Interventions that can be easily implemented in the clinic are needed. Objective To assess the immediate effects of sound-intensity feedback related to(More)
BACKGROUND Only a small amount of evidence exists linking hip abductor weakness to dynamic knee valgus during static and dynamic activities. The associations of hip extensor strength and hip kinematics during the landing of a single leg hop are not known. Purpose: To determine if relationships exist between hip extensor and abductor strength and hip(More)
