Motor control strategies revealed in the structure of motor variability.

چکیده
We describe an uncontrolled manifold hypothesis, which suggests a particular solution for the notorious problem of motor redundancy. A body of recent experiments supports the uncontrolled manifold hypothesis and shows its ability to discover biological strategies of the coordination of apparently redundant motor systems. The hypothesis and associated computational apparatus have great potential for application in the areas of motor rehabilitation and motor skill acquisiton.

Pain-Induced Impact on Movement: Motor Coordination Variability and Accuracy-Based Skill
Studies on pain are generally conducted for two purposes: first, to study patients with pain who have physical changes due to nerve and muscle lesions, and second, to regain the appropriate kinematic post-pain pattern. The present study aimed to investigate the effect of pain on the coordination variability pattern and throw accuracy. Participants included 30 people with a mean age of 18-25 yea...

In this study we manipulate structure of combined practice (physical along with self-modeling of positive self-review) to examine its effects on motor memory reconsolidation process and motor transfer in children. 36 female students (9-12 years old) from Maktabi elementary school of Qom trained Dart throwing. Of the 15 trials (from 1.5, 2, and 2.5 meters in blocked order), Positive self-re...

Fast and accurate transient response is the main requirement in electric machine position control. Conventional cascade control structure has sluggish response due to the limitation of inner control loop bandwidth. In this paper, in order to decrease the Permanent Magnet Synchronous Motor (PMSM) transient response time it can be used reference model using feed-forward signals. In this structure...
