BACKGROUND/AIMS: Posterior retroperitoneoscoic adrenalectomy has been reported as an option for adrenal tumor resection but is not commonly performed in children owing to the extreme semikneeling position advocated to flatten the lumbar lordosis in order to achieve adequate retroperitoneal space. As children have smaller lordosis angles, flattening of the lordosis and creation of optimal retroperitoneal space may be achieved with less hip flexion. We used pediatric lumbar lordosis measurements to develop a modified prone jackknife position and report our experiences with this setup for posterior retroperitoneoscopic adrenalectomy for adrenal tumors...

BACKGROUND: The act of babywearing is recognizably a task of load carriage and has gained popularity among millennial caregivers. RESEARCH QUESTION: The implications of babywearing on lower extremity joint moments of the caregiver are still unknown during prolonged transport and a direct comparison of babywearing to carrying an infant in-arms has not been previously conducted. METHODS: Eighteen females participated in this study by performing 3 conditions: a) 3 min walking unloaded (UL), b) 15 min walking while carrying a mannequin infant in-arms (IA), and c) 15 min walking while wearing a mannequin infant in an anteriorly positioned baby carrier (BC)...

The head of femoral bone is deformed in the subjects with Leg Calve Perthes disease (LCPD). This may be due to the excessive loads applied on it. There are no studies that report the hip joint contact force in subjects with LCPD. Therefore, the aim of this study was to evaluate the hip joint contact force in subjects with Perthes disease. Ten typically-developing (TD) children and 10 children with LCPD were recruited in this study. The kinematics and kinetics of the subjects were evaluated in 3D motion analysis...

BACKGROUND: Recovery of walking is a primary rehabilitation goal of most stroke survivors. Control of pelvic movements is one of the essential determinants of gait, yet surprisingly, conventional robot-assisted gait trainers constrain pelvic movements. Novel robot-assisted gait trainers, such as LOPES II, are able to support pelvic movements during gait. The aim of this cross-over study was to investigate the immediate after-effects of pelvic support (PS) or pelvic constraint (PC) gait training with LOPES II on overground walking in healthy subjects...

In team sports, non-contact ACL and MCL injuries occur during abrupt changes of direction, like turns or cutting manoeuvres. Fatigue affects dynamic neuromuscular control and increases knee injury risk. This study analysed how lower limb joints and centre-of-mass kinematics are affected throughout a high-intensity running protocol involving repeated 180°-turns. Twenty young men (18-23 years, BMI: 20.8-24.4 kg m-2 ) completed a 5-m shuttle running trial lasting 5 min at an average speed of 75% of their maximum aerobic speed...

In an analysis of NHANES 2005-2006, older, but not younger, women and men with higher levels of physical activity had higher TBS, total hip T-score, and femoral neck T-score. Even modest levels of physical activity may be a crucial component of bone health maintenance. PURPOSE: Physical activity is associated with improved bone parameters in adolescence, but it is not clear if this persists into adulthood. Further, it is unclear how low levels of physical activity as measured by accelerometer may impact bone parameters...

BACKGROUND: Wrist-worn accelerometers are increasingly used in epidemiological studies to record physical activity. The accelerometer data are usually only analyzed if the convention for compliant wear time is met (i.e. ≥ 10 h per day) but the algorithms to detect wear time have been developed based on data from hip-worn devices only and have not been tested in a free-living setting. The aim of this study was to validate the automatic wear time detection algorithms of one of the most frequently used devices in a free-living setting...

Work metabolism (WM) can be accurately estimated by oxygen consumption (VO2 ), which is commonly assessed by heart rate (HR) in field studies. However, the VO2 -HR relationship is influenced by individual capacity and activity characteristics. The purpose of this study was to evaluate three models for estimating WM compared with indirect calorimetry, during simulated work activities. The techniques were: the HR-Flex model; HR branched model, combining HR with hip-worn accelerometers (ACC); and HR + arm-leg ACC model, combining HR with wrist- and thigh-worn ACC...

Background: Exercise interventions can result in weight loss, which is associated with reductions in disease risk. It is unknown how the volume of exercise prescribed in a one-time exercise intervention impacts long-term body fatness. We compared 24-month body fat changes among postmenopausal women previously prescribed 300 versus 150 minutes/week of exercise in a year-long exercise intervention trial. Methods: The Breast Cancer and Exercise Trial in Alberta (BETA) was a two-centred randomized controlled trial in Alberta, Canada...

The purpose of this study was to investigate the immediate and sustained effects of static stretching (SS), dynamic stretching (DS) with no-load (DSNL), DS with a light load (DSLL, 0.25 kg), and DS with a heavy load (DSHL, 0.5 kg) on the hip joint range of motion (ROM). Sixteen participants (63.2 ± 7.13 years) were randomly assigned to perform SS, DSNL, DSLL, and DSHL exercises. The ROM for passive flexion and extension of the right hip joint was measured at pretest, as well as immediately after and at 60 min after completing the exercise...

INTRODUCTION: In the Emergency Department, regional anesthesia is increasingly used in elderly patients with hip fractures. An example is a Fascia Iliaca Compartment Block (FICB). Traditionally, this block is administered below the inguinal ligament. There is no Emergency Department data regarding effectivity of an alternative, more cranial approach above the inguinal ligament. The objective was to determine analgesic effects of an ultrasound-guided supra-inguinal FICB in hip fracture patients in the Emergency Department...
