Impact of time on quality of motor control of the paretic upper limb after stroke

They must have managed not to get any patients that had dead arm/hand motor control areas.  I still can't do reach-to-grasp, unable to open the hand, unable to reach due to spasticity.

Abstract: Study investigated the time course of recovery regarding smoothness of upper limb movements in the first 6 months after stroke. Forty-four patients with a first-ever unilateral ischemic stroke and incomplete upper limb paresis underwent a clinical and 3-dimensional kinematic assessment of the upper paretic limb in weeks 1, 2, 3, 4, 5, 8, 12, and 26 poststroke. In each measurement, an electromagnetic motion tracker acquired hand and finger trajectories during a reach-to-grasp task. Movement duration was determined, and smoothness of hand transport and grasp aperture was quantified by normalized jerk. With the use of random coefficient analysis, the effect of progress of time on smoothness of hand transport and grasp aperture was investigated. During the first 5 weeks poststroke, there was a significant contribution of progress of time to reductions in movement duration and normalized jerk of hand transport and grasp aperture. The progress of time contributed significantly to improvements in smoothness until week 8 poststroke. This improvement suggests that motor control normalizes and can be mostly explained by spontaneous neurologic recovery that occurs typically in the first weeks poststroke.
