“…11,16,17,25,30 In particular, the biarticular muscles are thought to transfer energy from the proximal to distal joints during jumping and from distal to proximal during landing. 11,17,25,32 The pattern of muscle power production observed in this study tends to support this assertion as the biarticular muscles studied tended to produce positive and negative power simultaneously at their respective joints (Fig. 5).…”

“…A number of researchers have sought to understand the function of the biarticular muscles by employing the combination of inverse dynamics and optimization techniques. 10,24,32 The majority of this study is based on finding the inverse dynamics solution using traditional techniques and then performing sensitivities on the effect of the biarticular muscles on the optimization solution. This approach is limited by the fact that the inverse dynamics method of finding the inter-segmental moments neglects the role of the biarticular muscles as seen earlier.…”

“…The clinical aim of the study was to use this new technique to explore the postulated role of the biarticular muscles in transferring energy between segments. In particular, a number of groups have reported that the biarticular muscles act to transfer energy between segments during jumping and landing, 11,17,25,32 thus vertical jumping was considered to represent an appropriate model to explore biarticular muscle function.…”

Traditional inverse dynamics approaches to calculating the inter-segmental moments are limited in their ability to accurately reflect the function of the biarticular muscles. In particular they are based on the assumption that the net inter-segmental moment is zero and that total joint moments are independent of muscular activity. Traditional approaches to calculating muscular forces from the inter-segmental moments are based on a consideration of joint moments which do not encapsulate the potential moment asymmetry between segments. In addition, traditional approaches may artificially constrain the activity of the biarticular muscles. In this study, an optimization approach to the simultaneous inverse determination of inter-segmental moments and muscle forces (the 1-step method) based on a consideration of segmental rotations was employed to study vertical jumping and contrasted with the more traditional 2-step approach of determining inter-segmental moments from an inverse dynamics analysis then muscle forces using optimization techniques. The 1-step method resulted in significantly greater activation of both the monoarticular and biarticular musculature which was then translated into significantly greater joint contact forces, muscle powers, and inter-segmental moments. The results of this study suggest that traditional conceptions of inter-segmental moments do not completely encapsulate the function of the biarticular muscles and that joint function can be better understood by recognizing the asymmetry in inter-segmental moments.

“…They supposed that the biarticular muscles contributed to energy transfer (Jacobs et al 1996;Voronov 2004) and to direction of external force (Doorenbosch et al 1996;Fukashiro et al 2005). However, since we cannot intentionally control each muscle, only we can observe is its role in the context of whole body synergy.…”

“…Following observation in biomechanics, we assume that biarticular muscles mainly contributes to transfer force/ power whereas monoarticular ones contribute to generate power (Voronov 2004). Therefore, we do not actively control the biarticular muscles during movement, that is, the valves for the muscles are closed during experiment after initial supply.…”

Pneumatic-driven jumping robot with anthropomorphic muscular skeleton structure

et al. 2009

Human muscular skeleton structure plays an important role for adaptive locomotion. Understanding of its mechanism is expected to be used for realizing adaptive locomotion of a humanoid robot as well. In this paper, a jumping robot driven by pneumatic artificial muscles is designed to duplicate human leg structure and function. It has three joints and nine muscles, three of them are biarticular muscles. For controlling such a redundant robot, we take biomechanical findings into account: biarticular muscles mainly contribute to joint coordination whereas monoarticular muscles contribute to provide power. Through experiments, we find (1) the biarticular muscles realize coordinated movement of joints when knee and/or hip is extended, (2) the extension of the ankle does not lead to coordinated movement, and (3) we can superpose extension of the knee with that of the hip without losing the joint coordination. The obtained knowledge can be used not only for robots, but may also contribute to understanding of adaptive human mechanism.
