	abstract = {Reaching movements are often used to study the effectiveness of 
		motor control processes with respect to the final position of 
		arm and hand. Empirical evidence shows that different targets 
		can be grasped with similar final position accuracy. However, 
		movements that achieve similar accuracy at their final position 
		may nevertheless be controlled differently. In particular, 
		control strategies may differ in the control of the abundant 
		degrees of freedom with respect to the task-specific costs. The 
		objective of the present study was to investigate whether the 
		applied control strategy was influenced by the shape of the 
		target to be grasped. It was investigated whether mechanical 
		constraints, imposed on final hand orientation or final hand 
		position by the shape of the targets, affected the synergistic 
		coordination of the kinematic degrees of freedom of the arm. 
		Subjects were asked to grasp either a cylindrical or a spherical 
		target, which imposed different constraints on final hand 
		orientation and position. Besides temporal movement aspects, 
		variability of the joint angles of the arm, as well as 
		variability of hand orientation and hand position was analyzed 
		over the whole time course of movement execution, using the 
		uncontrolled manifold method. Overall movement duration differed 
		between cylindrical and spherical target condition, due to 
		differences in deceleration duration. Reaching movements towards 
		the cylindrical target, which was more constraint in final hand 
		orientation and position, took longer than movements towards the 
		spherical target. Analysis further revealed that the degrees of 
		freedom of the arm were synergistically coordinated to stabilize 
		both hand orientation and hand position, when grasping either 
		the spherical or the cylindrical target. This suggests that the 
		applied control strategy in natural reaching movements can 
		simultaneously account for multiple task constraints. The 
		analysis further revealed that stabilization of hand orientation 
		was stronger when reaching towards a cylindrical target, which 
		imposed more constraints on final hand orientation. In contrast, 
		hand position was more strongly stabilized in the spherical 
		target shape condition, where stronger constraints on final hand 
		position were applied. This suggests that different target 
		shapes do influence the control strategy of reaching movements 
		even though variability at movement end was not affected.},
