  • Determination of the Human Spine Curve Based on Laser Triangulation Primož Poredoš1*,Dušan Čelan2, Janez Možina1 and Matija Jezeršek1
    Poredoš et al. BMC Medical Imaging (2015) 15:2 DOI 10.1186/s12880-015-0044-5 RESEARCH ARTICLE Open Access Determination of the human spine curve based on laser triangulation Primož Poredoš1*,Dušan Čelan2, Janez Možina1 and Matija Jezeršek1 Abstract Background: The main objective of the present method was to automatically obtain a spatial curve of the thoracic and lumbar spine based on a 3D shape measurement of a human torso with developed scoliosis. Manual determination of the spine curve, which was based on palpation of the thoracic and lumbar spinous processes, was found to be an appropriate way to validate the method. Therefore a new, noninvasive, optical 3D method for human torso evaluation in medical practice is introduced. Methods: Twenty-four patients with confirmed clinical diagnosis of scoliosis were scanned using a specially developed 3D laser profilometer. The measuring principle of the system is based on laser triangulation with one- laser-plane illumination. The measurement took approximately 10 seconds at 700 mm of the longitudinal translation along the back. The single point measurement accuracy was 0.1 mm. Computer analysis of the measured surface returned two 3D curves. The first curve was determined by manual marking (manual curve), and the second was determined by detecting surface curvature extremes (automatic curve). The manual and automatic curve comparison was given as the root mean square deviation (RMSD) for each patient. The intra-operator study involved assessing 20 successive measurements of the same person, and the inter-operator study involved assessing measurements from 8 operators. Results: The results obtained for the 24 patients showed that the typical RMSD between the manual and automatic curve was 5.0 mm in the frontal plane and 1.0 mm in the sagittal plane, which is a good result compared with palpatory accuracy (9.8 mm).

To examine the effects of experimentally induced pain and fear of pain on trunk coordination and erector spinae EMG activity during gait. Design. In 12 healthy subjects, hypertonic saline (acute pain) and isotonic saline (fear of pain) were injected into erector spinae muscle, and unpredictable electric shocks (fear of impending pain) were presented during treadmill walking at different velocities, while trunk kinematics and EMG were recorded. Background. Chronic low back pain patients often have disturbed trunk coordination and enhanced erector spinae EMG while walking, which may either be due to the pain itself or to fear of pain, as is suggested by studies on both low back pain patients and healthy subjects. Methods. The effects of the aforementioned pain-related manipulations on trunk coordination and EMG were examined. Results. Trunk kinematics was not affected by the manipulations. Induced pain led to an increase in EMG variability and induced fear of pain to a decrease in mean EMG amplitude during double stance.

  • Factors That May Influence the Postural Health of Schoolchildren (K-12)
    WORK A Journal of Prevention, Assessment &. Rehabilitation ELSEVIER Work 9 (1997) 45-55 Factors that may influence the postural health of schoolchildren (K-12) Betsey Yeats 15 Hillsdale Road, Arlington, MA 02174, USA Received 20 June 1996; revised; accepted 11 Febuary 1997 Abstract Ergonomic seating and proper positioning during the performance of activities is a major focus in the adult workplace. This focus, however, is typically ignored in classrooms where our youngest workers spend the majority of their time. A review of the literature was done to determine the effects of school furniture design on the postural health of schoolchildren (K-12). The review indicated that the adjustability of school furniture is an important design feature if children are to have equal educational opportunity, increased comfort, and decreased incidences of musculoskeletal symptoms. The effectiveness of ergonomic school furniture on schoolchildren has been demon­ strated in only one study reviewed in this paper. The other studies are reviewed in an effort to identify: (1) the variation of anthropometric measures of children; (2) the performance of activities exposing children to various postures; and (3) the physical design features of school furniture as three factors which influence the postural health of schoolchildren. © 1997 Elsevier Science Ireland Ltd.

To test TSA success, most prior research compares patients with TSA to healthy controls. However, the shoulder anthropometry, motion, and musculature of individuals varies widely across the population making it important to assess TSA performance in individuals.

Box 1346 Ann Arbor, Ml 48106-1346 ABSTRACT Muscles of the human trunk are arranged in layers and attach either to the vertebral column or to the pelvis and thorax. Present understanding suggests the deeper muscles, attached to the vertebral column, stabilise the spine, whereas the more superficial muscles, attached to the thorax and pelvis, produce and control trunk movement. If so, the control of these two groups may differ, with deeper muscles working synergistically and those more superficially located acting antagonistically to one another. To this end the role that reflex connections between the different muscles may play in mediating either synergistic or antagonistic roles was investigated. Muscle afferent activity was evoked via a series of mechanical taps applied to individual muscle/tendon complexes of three abdominal and two paraspinal muscles by means of a mechanical tapping device.

Breglia June 2006 This thesis entitled GENERATION OF A 3-D PARAMETRIC SOLID MODEL OF THE HUMAN SPINE USING ANTHROPOMORPHIC PARAMETERS by DOUGLAS P. BREGLIA has been approved for the Department of Mechanical Engineering and the Russ College of Engineering and Technology by Bhavin Mehta Associate Professor of Mechanical Engineering R. Dennis Irwin Dean, Russ College of Engineering and Technology Abstract BREGLIA, DOUGLAS P., M.S., June 2006. Mechanical Engineering GENERATION OF A 3-D PARAMETRIC SOLID MODEL OF THE HUMAN SPINE USING ANTHROPOMORPHIC PARAMETERS (98 pp.) Director of Thesis: Bhavin Mehta It has been shown that there is a correlation between stature and the dimensions of the vertebra in humans [1]. The objective of this thesis is to create a computer model of the vertebra that is personalized based on external metrics. To accomplish this, a parametrically linked solid model of the vertebrae is linked to the height, sex, and ethnicity of an individual. Vertebral morphologies presented in the literature are used to create geometric primitives of each bone. Relationships from forensic science are used to relate an individual’s stature to the heights of each of the vertebrae. Also, relationships between the vertebral height and the other dimensions of the vertebra are derived. These together can be used to create a model of each vertebra that is modified according to external human parameters.
