The human motor system is mechanically complex and need to be described by using a large number of degrees of freedom. The controlled operation of such a system requires a reduction of mechanical redundancy. The coordination and synergies among the muscles and joints can be used for the reduction. In this paper, synergy is discussed through the analysis and comparison ...

The directions of endpoint forces in the horizontal plane exerted by individual muscles of the feline hindlimb were predicted using a musculoskeletal simulation and investigated by electrical stimulation of muscles in decerebrate cats. The vectorial directions were consistent with commonly accepted muscle attachments. Both approaches supported the hypothesis that distal muscles may play an important role in directing the force ...

The human motor system is mechanically complex and need to be described by using a large number of degrees of freedom. The controlled operation of such a system requires a reduction of mechanical redundancy. The coordination and synergies among the muscles and joints can be used for the reduction. In this paper, synergy is discussed through the analysis and comparison of human upper-limb pointing movements. All movements were recorded by a Vicon 3D motion analysis system. The synergy in the pointing movement of upper-limb was found among the different joint angles. A function method is used to describe the pointing performance. The different joint angles can be fitted by the same function curve. The pointing movement performance can be determined by the fitting parameter vector and the start and end states. Based on this result, a typical motion pattern can be described by a smaller set of variables.

The objective of the present study was to investigate whether changes in type I collagen molecules have a direct impact on the biomechanical integrity of the collagen network and bone. In this study, demineralized and non-treated bone specimens were incubated at room temperature, and the collagen denaturing temperatures: 65/spl deg/C and 180/spl deg/C, respectively. Tensile tests and fracture toughness tests were devised and performed to assess the mechanical integrity of the collagen network. The correlations of heat-induced denaturation of the collagen network with the biomechanical properties of the collagen network and bone were investigated. The results of this study indicate that heat induced collagen denaturation has a greater impact on the stiffness and strength than the toughness of the collagen network. It consequently leads to significant changes in the strength and toughness of bone. The results of this study suggests that stiffness and strength of the collagen network are more related to bone toughness and strength.

A new car seat design, which allows the back part of the seat (BPS) to lower down while a protruded cushion supports the lumbar spine, was quantitatively tested to determine its effectiveness in reducing whole-body vibration (WBV) in automobile drivers. Results on 12 drivers show that, by reducing contact between the seat and the ischial tuberosities (TTs), the new seating design reduced both contact pressure and amplitude of harmful vibrations transmitted through the body. Significant reduction of WBV, in terms of RMS and VDV, was found as large as 30% by this seating design (P < 0.05), especially at lumbar spine region. This reduction in WBV allows more sustained driving than permitted by conventional seating devices, by around 2 hours daily, before reaching harmful WBV levels. The new seating design also promotes improved posture by restoring normal spinal curvature. Such seating devices, implemented in cars, buses, large trucks, and other high-vibration vehicles, may effectively reduce the risk of musculoskeletal disorders among long term drivers.
A study on combined manual materials handling tasks performed on floors under three frequency levels was conducted. Eight male subjects participated in the study. The maximum acceptable weight of handling, including lifting, carrying for 3 m, lowering, and walking 3 m back at either 1, 2, or 3 per minute was determined. The subject then performed the same tasks for 10 minutes. The VO2, heart rate, and rating of perceived exertion for whole body strain were measured. The results showed that the effects of frequency on the maximum acceptable weights of handling, heart rate, and Vo2 were statistically significant (p<0.01). As the frequency level decreased from 3 to 1 per minute, the maximum acceptable weights of handling increased from 7.21 to 9.10 kg. The VO2, on the other hand, decreased from 713.2 to 462.5 ml per minute. The heart rate decreased from 103.8 to 93.0 beat per minute. The effects of frequency on RPE was, however, not significant. The implication of this study was that frequency should be regarded as one of the major job factors in designing MMH tasks as it affected both physiological responses of the subjects. High frequency resulted in both higher physiological measures for the subjects under our experimental conditions. This is consistent with the findings in the literature.
The Musculoskeletal Temporally Activated Novel Gene (Mustang) was identified by suppressive subtractive hybridization comparing bone fracture callus to intact bone. Mustang's peak in expression (50-fold over intact levels) was localized temporally to early time points during the Bone Fracture Repair (BFR) process that correspond to proliferation of chondrocyte progenitor cells and chondrogenesis at the fracture site. Further, this small protein contains a nuclear localization sequence and spatially localized to proliferating chondrocytes within the adult rat knee joint. These data suggests that Mustang may act as a transcriptional co-activator or co-repressor. The elucidation of Mustang's expression during the proliferation and differentiation of chondrocytes in vitro could help shed light on Mustang's function. To this end, Mustang was over expressed by stable transfection and silenced via RNAi in the RCJ 5.18 chondrocytic cell line. The over expression of Mustang up to six-fold in the RCJ cells showed no significant effect on either cell growth or matrix production. However, reduction of Mustang expression by 52-66% resulted in both a significant decrease in proliferation rate as well as diminished matrix production. This suggests that Mustang is necessary for chondrocyte proliferation as well as differentiation and possibly functions as a regulator of chondrogenesis.
Modelling is necessary to understand and evaluate the musculoskeletal system of the human body. Most of the developed models used anthropometrical and geometrical parameters of the bones and muscles from the literature. The aim of the present work was to study the sensitivity of anthropometrical (segment mass) and geometrical (physiologic cross-sectional area of the muscle) parameters on musculoskeletal model of the lower limbs for simulation of the gait. An inverse dynamic analysis was performed to activate the joints and muscles. Then a direct dynamic analysis was carried out with active joints and muscles. The influences of these parameters on the kinematics and kinetics simulation results were reported. The obtained results show an influence of these parameters on the simulation results (maximal relative error varying from 2 to 75 %). These results suggest subject specific parameters to be considered.
Damping characteristics of the musculoskeletal system were investigated during rapid voluntary wrist flexion movements. Oscillations about the final position were induced by coupling the wrist to a load which had the characteristics of negative viscosity. The greater the negative viscosity of the load, the greater the observed co-contraction of wrist flexor and extensor muscles. While wrist stiffness increased in parallel with the increased co-contraction, wrist viscosity varied in a more complex manner that appeared to depend on both velocity of oscillation and reflex force produced by muscle stretch.
