“…where With the model assumptions, only the gravity of the arm and hand is taken into the minimization. And a natural human arm posture is considered to be the result of minimizing the index of the muscular effort among all the possibilities [25,28,29]. Therefore, the muscle-effort-minimization problem is formulated as minimization (3) with the total sum of squared muscle activations, where…”

“…Demircan et al [27] showed the practicality of a biology measure that encodes information about the musculoskeletal system of human arms. In [28,29], a natural human arm posture is considered to be the result of minimizing an index of muscular effort. However, Lamperti et al [28] adopted a simplified 7-DoF arm model to estimate muscle efforts, which may contribute to a degraded estimation accuracy.…”

“…Since the motion is generated off-line, it is not capable to adapt to change in an environment, and additional equipment is required to capture a healthy individual's motion. Some theories suggest that the human Central Nervous System (CNS) plans movements based on the principle of minimizing specific costs, such as minimizing motion jerk in task space [12]- [14], angular jerk [15], squared variation of joint torque [16], [17] and muscle effort [18], [19]. How to choose the specific costs is not obvious, and it is indeed a very debated topic in literature [20].…”
