Estimation of finger muscle tendon tensions and pulley forces during specific sport-climbing grip techniques

An introductory study of common grasps used by adults during performance of activities of daily living

“…Different types of grasp are often used 22 *3) Blinded Manuscript (without author details) 2 for simulation in biomechanical research to perform studies conducted for very different 23 purposes [6][7][8][9][10][11] : to understand the role of the different anatomical elements, to deepen the 24 knowledge about the effects of pathologies and the surgical procedures used to treat them, 25 and to help in the design of prostheses and biomedical implants. However, the importance of 26 the different types of grasp with respect to the ability to perform activities of daily living 27 (ADL) should be considered in order to obtain useful conclusions from all these simulations.…”

Towards a Realistic and Self-Contained Biomechanical Model of the Hand

“…These too are quantitative analyses performed on dynamic models. Recent models do not differ much from the ones developed before 2000 (Fok & Chou, 2010;Kamper et al, 2006;Kurita et al, 2009;Lee et al, 2008aLee et al, , 2008bQiu et al, 2009;Roloff et al, 2006;Sancho-Bru et al, 2001, 2003a, 2003b, 2008Valero-Cuevas, 2000;Valero-Cuevas et al, 2000, 2005Vigouroux et al, 2006Vigouroux et al, , 2008Wu et al, 2010). All models present a similar configuration.…”

“…By the year 2000, few threedimensional models had been developed (Biryukova & Yourovskaya, 1994;Casolo & Lorenzi, 1994;Chao et al, 1976;Chao & An, 1978;Esteki & Mansour, 1997;Mansour et al, 1994;ValeroCuevas et al, 1998), and none of them modelled the complete hand. Since 2000, many three-dimensional biomechanical models can be found in literature, having been developed for very different purposes (Fok & Chou, 2010;Kamper et al, 2006;Kurita et al, 2009;Lee et al, 2008aLee et al, , 2008bQiu et al, 2009;Roloff et al, 2006;Sancho-Bru et al, 2001, 2003a, 2003b, 2008Valero-Cuevas, 2000;Valero-Cuevas et al, 2000, 2005Vigouroux et al, 2006Vigouroux et al, , 2008Wu et al, 2010): to understand the role of the different anatomical elements, to understand the causes and effects of pathologies, to simulate neuromuscular abnormalities, to plan rehabilitation, to simulate tendon transfer and joint replacement surgeries, to analyse the energetics of human movement and athletic performance, to design prosthetics and biomedical implants, to design functional electric stimulation controllers, to name a few. These models, however, do not differ much from the ones developed before 2000, and many limitations are still evident.…”

Effect of hip flexibility on optimal stalder performances on high bar

“…Since the purpose was to compare optimum stalders for different hip flexibilities, the arbitrary value of 100 Nm was not a limit of our study. However for other purposes ─ performance optimization and analysis of mechanical work (Silder et al, 2008) or muscular force estimation for actual performances (Vigouroux et al, 2006) ─, a subject-specific model would be important. The passive torque model could be improved by considering both hip flexion and abduction using an isokinetic dynamometer and electromyography.…”
