PURPOSE The purpose of this study was to establish normative values for active lumbar movement in children five, seven, nine, and 11 years of age. METHODS End range active flexion, extension, and right- and left-side bending and rotation of the lumbar spine were measured for 225 normally developing children (116 girls, 109 boys) using the Back Range of Motion (BROM II) device. Means were dete...

The link between static and dynamic landing lumbar postures, when gymnasts are exposed to large ground reaction forces, has not been established. This investigation aimed to (a) determine if a relationship exists between sagittal static and dynamic landing lumbar spine angles at peak ground reaction force (GRF) and (b) quantify how close to end-range postures the gymnasts were at landing peak G...

BACKGROUND Rehabilitation of elderly patients with sit-to-stand (STS) dysfunction includes retraining coordinated movement among participating body segments. Although trunk position is considered important, spinal movement has not been measured. OBJECTIVE The aim of this study was to describe the sagittal thoracolumbar kinematics and hip-lumbar interaction during the STS task in elderly peopl...

OBJECTIVE The relationship between OA and osteoporosis has exhibited contradictory features over the past four decades. The aim of this study was to determine using separate analysis of the radiographic features of OA whether various radiographic features of OA were associated differently with BMD in the Korean elderly. METHODS Data were derived from the Dong-gu cohort; 2354 subjects were enr...

BACKGROUND Kidney dysfunction and albuminuria may be associated with BMD. However, little evidence has been reported on relationships between BMD and eGFR and albuminuria. METHODS A total of 8,992 subjects aged 50 years or older participated in a survey conducted. Participants had their lumbar spine and femoral neck BMD measured by a Lunar Prodigy bone densitometer (GE, Madison, WI). Kidney f...

RATIONALE Currently available approaches to osteoporosis treatment include application of antiresorptive and anabolic agents influencing bone tissue metabolism. The aim of the study was to present bone mineral density (BMD) changes of lumbar spine in osteoporotic patient treated with bisphosphonates such as ibandronic acid and pamidronic acid, and beta-hydroxy-beta-methylbutyrate (HMB). PATIE...

AIM Laboratory training models are essential for developing and refining treatment skills before the clinical application of surgical and invasive procedures. A simple simulation model is needed for young trainees to learn how to handle instruments, and to perform safe lumbar transforaminal epidural injections. Our aim is to present a model of a fresh cadaveric sheep lumbar spine that simulates...

As the nature of many materials handling tasks have begun to change from lifting to pushing and pulling, it is important that one understands the biomechanical nature of the risk to which the lumbar spine is exposed. Most previous assessments of push-pull tasks have employed models that may not be sensitive enough to consider the effects of the antagonistic cocontraction occurring during comple...

STUDY DESIGN Retrospective case-control study. PURPOSE To determine whether kissing spine is a risk factor for recurrence of sciatica after lumbar posterior decompression using a spinous process floating approach. OVERVIEW OF LITERATURE Kissing spine is defined by apposition and sclerotic change of the facing spinous processes as shown in X-ray images, and is often accompanied by marked dis...
