BACKGROUND: Children with chronic kidney disease are frequently born small for gestational age (SGA) and prone to disproportionately short stature. It is unclear how SGA affects growth after kidney transplantation (KTx). METHODS: Linear growth (height, sitting height, and leg length) was prospectively investigated in a cohort of 322 pediatric KTx recipients, with a mean follow-up of 4.9 years. Sitting height index (ratio of sitting height to total body height) was used to assess body proportions...

We aimed to measure thoracic dimensions and volume in relation to growth and verify the influence of scoliosis on thoracic growth. A reference group of 294 healthy volunteers was compared with a group of 557 patients with idiopathic scoliosis ranging in age from 3 to 25 years. The optical ORTEN system for trunk surface data acquisition was used to calculate thoracic volume, perimeter, anterior-posterior and transversal diameters, T1-T12 length, and sternal length. There was no significant difference in thoracic dimensions and volume between scoliosis and reference groups in either girls or boys...

To prevent back and shoulder injuries to nursing personnel, sit-to-stand lifts are used to transfer partial-weight-bearing patients with upper extremity strength. However, the weight-bearing capacity and upper extremity strength required of patients have not been defined. The objectives of this study were to determine: (a) the percentage of body weight borne by the patient when lifted to different heights in the lift and (b) whether a patient needs upper extremity strength. Nineteen healthy normal-weight volunteers (ages 19-39) were transferred from a hospital bed to a wheelchair using (a) a gait belt and (b) a sit-to-stand lift...

Individuals with sensorimotor pathology e.g., stroke have difficulty executing the common task of rising from sitting and initiating gait (sit-to-walk: STW). Thus, in clinical rehabilitation separation of sit-to-stand and gait initiation - termed sit-to-stand-and-walk (STSW) - is usual. However, a standardized STSW protocol with a clearly defined analytical approach suitable for pathological assessment has yet to be defined. Hence, a goal-orientated protocol is defined that is suitable for healthy and compromised individuals by requiring the rising phase to be initiated from 120% knee height with a wide base of support independent of lead limb...

OBJECTIVES: The purpose of this study was to correlate sitting height measured by stadiometry with lumbar spine height (LSH) modifications measured by musculoskeletal ultrasonography (MSU). METHODS: Eighteen healthy young adults were recruited for this study (mean age: 21.5 ± 1.5 years). All subjects were tested in the following sequence: (1) lying supine for 10 minutes, (2) sitting under loaded (9.5 kg) and unloaded conditions for 5 minutes each, (3) lying supine for 15 minutes with passive lumbar extension, and (4) sitting unloaded for 5 minutes...

BACKGROUND: Thoracolumbar kyphosis (TLK) is common in infants with achondroplasia. Our goals were to examine the natural history of TLK and identify factors associated with persistent TLK. METHODS: We reviewed records of patients with achondroplasia seen by a board-certified orthopaedic surgeon at a tertiary care medical center between 1997 and 2013. Inclusion criteria were minimum 2-year follow-up and radiographs taken at time of presentation, within 6 months of walking age, and within 6 months of the first anniversary of walking age...

To date, there has been no study done investigating the relationship between the components of height and blood pressure (BP) in rural South African children. Therefore, the aim of this study was to investigate the relationship between height, sitting height (SH), leg length (LL), and SH-to-height ratio (SH/H) with BP in Ellisras rural children. All children underwent anthropometric and BP measurements using standard procedure. Linear regression was used to assess the relationship between height, SH, LL, SH/H, and BP...

Familial dysautonomia is an inherited autonomic disorder with afferent baroreflex failure. We questioned why despite low blood pressure standing, surprisingly few familial dysautonomia patients complain of symptomatic hypotension or have syncope. Using transcranial Doppler ultrasonography of the middle cerebral artery, we measured flow velocity (mean, peak systolic, and diastolic), area under the curve, pulsatility index, and height of the dictrotic notch in 25 patients with familial dysautonomia and 15 controls...

Our sense of vision reliably directs and guides our everyday actions, such as reaching and walking. This ability is especially fascinating because the optical images of natural scenes that project into our eyes are insufficient to adequately form a perceptual space. It has been proposed that the brain makes up for this inadequacy by using its intrinsic spatial knowledge. However, it is unclear what constitutes intrinsic spatial knowledge and how it is acquired. We investigated this question and showed evidence of an ecological basis, which uses the statistical spatial relationship between the observer and the terrestrial environment, namely, the ground surface...

BACKGROUND: Office workers spend a large proportion of their working hours sitting. This may contribute to an increased risk of chronic disease and premature mortality. While there is growing interest in workplace interventions targeting prolonged sitting, few qualitative studies have explored workers' perceptions of reducing occupational sitting outside of an intervention context. This study explored barriers to reducing office workplace sitting, and the feasibility and acceptability of strategies targeting prolonged sitting in this context...

Deformation of the medial longitudinal arch under body weight loading is often assessed using the Arch Height Index Measurement System. This system assesses change in arch height between sitting and standing, estimated to be 10% and 50% of body weight, respectively. However, body weight forces during ambulation exceed these loads, therefore limiting our understanding of arch deformation under ambulatory load ranges. Thus, the study aims were (1) to assess if sitting and standing arch height differed from that seen under 10% and 50% body weight using a force target-matching procedure, and (2) to quantify the assumed linearity of arch stiffness, measured statically, throughout an ambulatory load range...
