“…Further, the axes of rotation of the thumb's joints were modeled in separated revolute joints as depicted by Hollister et al (1995). To reduce the complexity, the carpal bones were treated as one rigid body as in other models described in the literature (Lee et al 2015b;Mirakhorlo et al 2018;Ma'touq et al 2019). The wrist joint has two rotational axes according to Kobayashi et al (1997), which implies flexion/extension and ab/adduction.…”

“…To our knowledge, no previously described musculoskeletal model of the hand and wrist has been implemented for muscledriven, forward-dynamics simulations of both coordinated kinematic and kinetic functional tasks. Recently, several musculoskeletal models that include all the digits and major muscles of the hand have been developed [13][14][15][16][17]. However, few of these models are open-source and most are either not intended for or have not yet been shown to be usable for the full range of biomechanical tasks we describe here.…”

Objective: The purpose of this work was to develop an open-source musculoskeletal model of the hand and wrist and to evaluate its performance during simulations of functional tasks. Methods: The musculoskeletal model was developed by adapting and expanding upon existing musculoskeletal models. An optimal control theory framework that combines forward-dynamics simulations with a simulated-annealing optimization was used to simulate maximum grip and pinch force. Active and passive hand opening were simulated to evaluate coordinated kinematic hand movements. Results: The model's maximum grip force production matched experimental measures of grip force, force distribution amongst the digits, and displayed sensitivity to wrist flexion. Simulated lateral pinch strength fell within variability of in vivo palmar pinch strength data. Additionally, predicted activation for 7 of 8 muscles fell within variability of EMG data during palmar pinch. The active and passive hand opening simulations predicted reasonable activations and demonstrated passive motion mimicking tenodesis, respectively. Conclusion: This work advances simulation capabilities of hand and wrist models and provides a foundation for future work to build upon. Significance: This is the first open-source musculoskeletal model of the hand and wrist to be implemented during both functional kinetic and kinematic tasks. We provide a novel simulation framework to predict maximal grip and pinch force which can be used to evaluate how potential surgical and rehabilitation interventions influence these functional outcomes while requiring minimal experimental data.

“…Therefore, when the moment arms of the proposed model fit experimental data, the resulting muscle activities and joint reaction forces of the hand should also correspond to reality. Furthermore, the above-mentioned models of Holzbaur et al [2], Lee et al [9], Mirakhorlo et al [10], and Ma'touq et al [11] were validated comparing muscle moment arms. However, as stated in the literature [12,13], there are many more ways to confirm the validity of a musculoskeletal model.…”

Regarding the prevention of injuries and rehabilitation of the human hand, musculoskeletal simulations using an inverse dynamics approach allow for insights of the muscle recruitment and thus acting forces on the hand. Currently, several hand models from various research groups are in use, which are mainly validated by the comparison of numerical and anatomical moment arms. In contrast to this validation and model-building technique by cadaver studies, the aim of the present study is to further validate a recently published hand model [1] by analyzing numerically calculated muscle activities in comparison to experimentally measured electromyographical signals of the muscles. Therefore, the electromyographical signals of 10 hand muscles of five test subjects performing seven different hand movements were measured. The kinematics of these tasks were used as input for the hand model, and the numerical muscle activities were computed. To analyze the relationship between simulated and measured activities, the time difference of the muscle on- and off-set points were calculated, which resulted in a mean on- and off-set time difference of 0.58 s between the experimental data and the model. The largest differences were detected for movements that mainly addressed the wrist. One major issue comparing simulated and measured muscle activities of the hand is cross-talk. Nevertheless, the results show that the hand model fits the experiment quite accurately despite some limitations and is a further step towards patient-specific modelling of the upper extremity.
