“…There are several musculoskeletal shoulder models in the literature (Karlsson and Peterson 1992;van der Helm 1994avan der Helm , 1994bGarner and Pandy 2001;Holzbaur et al 2005;Damsgaard et al 2006;Quental et al 2012), developed for solving the musculo -tendon force coordination problem. However, some models present inconsistencies with in vivo measured data.…”

“…Therefore, the goal of this paper was to present an analysis of the solution space of the musculo -tendon force coordination problem to determine the cause of DLTa's underestimated activity. The analysis was done using a shoulder model (28-fibre model) topologically almost identical to the VHP model from the literature (Garner and Pandy 2001;Quental et al 2012). The model used in this paper was built using a different data-set collected from MRI scans but has the same number of bony landmarks and muscle fibres as the VHP model.…”

“…Dysfunctions limit concerned individuals in their daily activities. As such, a number of musculoskeletal models have been developed to improve our understanding of its physiology: the Delft shoulder and elbow model (DSEM) (van der Helm 1994a(van der Helm , 1994bNikooyan et al 2010), the Swedish model (Högfors et al 1987(Högfors et al , 1991Karlsson and Peterson 1992;Makhsous et al 1999), the Visible Human Project (VHP) model Pandy 1999, 2001;Quental et al 2012), the shoulder model of the AnyBody modelling software (Damsgaard et al 2006), the Stanford model available in opensim (Holzbaur et al 2005;Webb 2011) and the Newcastle model (Charlton and Johnson 2006). There are a number of other models that have been reviewed in the literature (Yang et al 2010;Prinold et al 2013).…”

Modelling the shoulder's musculature is challenging given its mechanical and geometric complexity. The use of the ideal fibre model to represent a muscle's line of action cannot always faithfully represent the mechanical effect of each muscle, leading to considerable differences between model-estimated and in vivo measured muscle activity. While the musculotendon force coordination problem has been extensively analysed in terms of the cost function, only few works have investigated the existence and sensitivity of solutions to fibre topology. The goal of this paper is to present an analysis of the solution set using the concepts of torque-feasible space (TFS) and wrench-feasible space (WFS) from cable-driven robotics. A shoulder model is presented and a simple musculo -tendon force coordination problem is defined. The ideal fibre model for representing muscles is reviewed and the TFS and WFS are defined, leading to the necessary and sufficient conditions for the existence of a solution. The shoulder model's TFS is analysed to explain the lack of anterior deltoid (DLTa) activity. Based on the analysis, a modification of the model's muscle fibre geometry is proposed. The performance with and without the modification is assessed by solving the musculo -tendon force coordination problem for quasi-static abduction in the scapular plane. After the proposed modification, the DLTa reaches 20% of activation.

“…2;2017 finger joints have one degree of freedom and the finger-to-palm joints each have two degrees of freedom. The further reduction of the system dimensionality, due to joint constraints, without introducing natural bio-mechanical structures is considered briefly later in the section on joints (Quental et al, 2012;Kapandji, 1979).…”

A basic 22-segment model of the upper extremity is formulated that can allow computational testing of hypotheses about the control and coordination of the upper extremity by the central nervous system. The formulation allows for further analytical, anatomical, physiological, and bio-mechanical expansion and improvement of the model. It allows for inclusion of all passive structures: ligaments, membranes, soft tissues, and cartilages. The formulation is based on the state space formulation of the Newton-Euler method applied to multi-body systems. Extensive use is made of three-segment rigid body modules, constraints, reduction of dimensionality, projection, and matrices of large dimensions.An example, gliding motion of a rigid body on a circular surface (as in wiping a dish with a pre-specified force of contact) shows the application of some of the concepts and feasibility of the developed routines. The control is based on analogous strategies in living systems where co-activation of agonist-antagonist muscular systems and precise reference inputs implement the desirable trajectories of motion and where an integral feedback of the force implements the desired forces of contact.
