Effect of links’ center of gravity position on the performance of a four-bar linkage as an upper limb rehabilitation mechanism: A parametric study
(Springer Verlag, 2016)It has been shown that mechanisms based on closed kinematic chains, with integrated passive elements (springs) can generate motions that replicate the natural hand motion and therefore they can be potentially useful in ...
