“…The finding that gait belt transfers exceed the NIOSH-recommended safe limit for compressive force is consistent with prior reports (Garg et al, 1991a, 1991b; Marras et al, 1999). In addition, some studies have reported associations between body anthropometry and the geometry of lumbar spine and paraspinal muscles (Gungor et al, 2015a, 2015b; Tang, 2013; Tang et al, 2016; Tang et al, manuscript submitted for publication); however, the relationships between anthropometric characteristics and risk of low back pain remain unclear (Frymoyer, 1992; Manchikanti, 2000; Rubin, 2007; Sesek et al, 2014), and must be addressed in future investigations.…”

Nursing personnel, particularly caregivers who frequently perform manual patient transfer tasks, are at risk for work-related musculoskeletal disorders (WMSDs). The purpose of this study was to perform biomechanical evaluations of bed-to-wheelchair transfer using two low-cost assistive devices: walking belt and gait belt. Twenty-eight college students, serving as caregivers, transferred 14 students, serving as patients. "Caregiver" spinal loading and strength requirements at major joints were measured using a 3D Static Strength Prediction Model. "Caregiver"-perceived stresses were assessed using the Borg CR-10 Scale. "Patient" safety and comfort ratings were determined using Likert-type scales. The findings indicated that transferring "patients" using walking belts with a pulling technique produced significantly lower biomechanical stress than using gait belts. "Patients" also felt more comfortable and safer during walking belt transfers. It is recommended that health care facilities should consider use of walking belts in place of gait belts to transfer partially weight-bearing patients.

“…segments. Because the intervertebral space morphology dictates that artificial intervertebral space designs cannot be designed to be directly rectangular [11], this study also found that the intervertebral gap height median height in the L5/S1 and L4/5 segments compared to the right and left sides of the spine Large in the middle and small on the left and right side need to be designed to have a large middle height of the vertebral space and a small height of the vertebral space on both sides, which can improve the biomechanics of the spine.…”

Background: Based on CT images of the thoracolumbar intervertebral foramen and its surrounding parameters, and analyzing the intervertebral foramen morphology and the correlation between the measured parameters, to provide an anatomical basis for clinical minimally invasive transvertebral surgery. Materials and methods: Ten fresh adult cadaveric specimens (32-50 years old) with bilateral (T1-S1) spinal segments were selected for a total of 20 sides, a total of 340 intervertebral foramen, were measured with vernier calipers in the Department of Anatomy, Inner Mongolia Medical University. The intervertebral foramen height, the minimum sagittal diameter of the foramen, the width of the spinal ganglion, the sagittal diameter of the spinal ganglion and the sagittal diameter of the intervertebral foramen were measured. This study was reviewed and approved by the local Ethics Committee. Results: The results of the minimum sagittal diameter of the T9-10~L5/S1 intervertebral foramen were 6.

Mathematical modeling of individual parameters of the sum of the sizes intervertebral discs of the lumbar spine in juvenile males and males of the first mature age in norm

In nowadays, an important area in medicine is the early preclinical identification of the parameters deviations from the norm, where mathematical modeling can help, which should be used to calculate individual linear parameters of internal structures based on external parameters of the body. The aim of the study was to calculate the individual total linear measures of the lumbar intervertebral discs in juniors and men of the first adulthood (17-28 years) in norm. The total size of the each intervertebral discs were calculated a sum of the anterior-posterior diameter, frontal diameter and vertical sizes of each lumbar intervertebral discs, which were measured by MRI. The next step was to calculate the relative proportional nonlinear somato-disc rates (based on body weight and body length) for each individual examined. Mathematical processing of the measured parameters and the relative values of the somato-disc relationships was carried out by the statistical data processing program “STATISTICA 6.1” using parametric methods. The correct distribution of the variational series indicators, mean values and their standard errors were evaluated. Based on relative values the mathematical model was created to obtain individual values of the TS of the lumbar intervertebral discs. Subsequently, we compared the measured total discs sizes of the anterior-posterior, frontal diameters and vertical sizes of the lumbar intervertebral discs with a mathematically calculated value for each lumbar intervertebral discs. The significant difference between the mathematically calculated and measured values of the total intervertebral discs’ sizes of the didn’t exceed 10%. Determination of the standard linear dimensions of the intervertebral discs of the lumbar spine using CT and MRI and comparison with theoretically calculated indices will make it possible to diagnose early manifestations of the lumbar intervertebral discs pathology.
