Discriminating spatiotemporal movement strategies during spine flexion-extension in healthy individuals
2019, Spine JournalCitation Excerpt :First, the current findings suggest that thoracic-lumbar CRP measures have the capability to differentiate distinct spatiotemporal sequencing strategies during spine flexion-extension. This expands on the utility of CRP as a measure to examine the coordination between absolute segment rotations of the thorax and pelvis [33,34], or relative rotations between the lumbar spine and lower limb joints [13,14,35]. Second, the results from the current work agree with previous studies that have investigated the spatiotemporal sequencing of spine motion.
Using relative phase analyses and vector coding to quantify Pelvis-Thorax coordination during lifting—A methodological investigation
2018, Journal of Electromyography and KinesiologyCitation Excerpt :Continuous relative phase (CRP) and vector coding (VC) are examples of techniques used to study spatiotemporal patterns in time-evolving systems and are thus hypothetically suited to quantify the pattern of relative rotations between the thorax and pelvis segments (i.e., lumbar spine coordination) during repetitive lifting. Indeed, relative phase analyses have been used extensively to study the effects of personal characteristics (Commissaris et al., 2002; Hu and Ning, 2015a, 2015b; McGorry and Hsiang, 1999; van Dieën et al., 1996) and task parameter manipulations (Burgess-Limerick, 1995; Scholz, 1993a, 1993b; Scholz and McMillan, 1995) on lifting technique, and as a means to describe and classify lifting techniques (Burgess-Limerick et al., 1993). To date, there have been no known attempts to use coupling angles (VC) to quantify spinal coordination during lifting, though similar/equivalent quantities (e.g., lumbopelvic ratios) have been used to describe how segments/joints contribute to trunk postures during dynamic activities (Vazirian et al., 2016).
Difference between male and female workers lifting the same relative load when palletizing boxes
2017, Applied ErgonomicsCitation Excerpt :They found that hip-knee coordination was more in phase (synchronized) in females during a squat lift, the hip extension lagging more behind knee extension in males. This was interesting, as females are generally weaker than males, and papers investigating hip-knee coordination have found that as the load weight increases, lumbar spine motion lags further behind the lower extremity joint motion (Davis and Troup, 1965; Scholz, 1993a; 1993b; Scholz and McMillan, 1995; Burgess-Limerick et al., 1995). Three studies adjusted the weight of the load to the subjects' true individual lifting capacity (Albert et al. (2008) = 20% relative load; Sadler et al. (2011) = 0% and 10% of maximum isometric back strength (MISB); Sheppard et al. (2016) = 10%, 20% and 30% MISB), and their results concluded that there were no significant sex effects in the lifting technique (kinematics of lifting).
A numerical tool to simulate the kinematics of the ingress movement in variably-dimensioned vehicles for elderly and/or persons with prosthesis
2015, International Journal of Industrial ErgonomicsCitation Excerpt :The methods based on knowledge suppose: To identify the constraints and the natural laws, physical and physiological, reducing the number of theoretical degrees of freedom of the human system (FITT's law (Van Galen and Shomaker, 1992; Van Galen and de Jong, 1995)), stability constraint (Kelso et al., 1987; Scholz, 1993a,b), invariance of the relative sequencing (Van Ingen Schenau et al., 1995), and the biomechanical constraints (Van Ingen Scheneau, 1990; Van Ingen Scheneau et al., 1992, 1995), To identify the control laws guiding the choice of a trajectory instead of another (movement programming (Pearson, 1993), assumption of the point of balance (Feldman and Levin, 1995, Van Galen and de Jong, 1995), satisfactory solution (Stein et al., 1988), optimization according to a criterion (Hsiang and Ayoub, 1994)).
Sex differences in lifting strategies during a repetitive palletizing task
2014, Applied ErgonomicsCitation Excerpt :Several papers investigated the coordination between lower extremity joints and the back and found that as the load weight increased, the lumbar spine motion was lagging further behind the lower extremity joint motion. In other words, the knee extension proceeded sooner than the back extension as the load lifted was increased; or the lumbar spine extension was delayed with heavier loads (Davis and Troup (1965); Scholz, 1993a, 1993b; Scholz and McMillan, 1995; Burgess-Limerick et al., 1995). Interjoint coordination appears to vary between sexes as well.
