Coupling phenomena during asynchronous submaximal two-hand, multi-finger force production tasks in humans.

We studied asynchronous two-hand multi-finger force production at submaximal levels. Subjects produced constant levels of force with one hand (F(REF)), and started ramp force production with the other hand (F(RAMP)) 3 s later. The zero-maximal force-zero ...

Enhancement of use-dependent plasticity by D-amphetamine.

In healthy individuals, motor training can elicit use-dependent plasticity. Here the authors studied six subjects in whom training alone failed to elicit this effect. Administration of a single dose of 10 mg of D-amphetamine preceding training led to ...

Association of orofacial with laryngeal and respiratory motor output during speech.

Speech motor coordination most likely involves synaptic coupling among neural systems that innervate orofacial, laryngeal, and respiratory muscles. The nature and strength of coupling of the orofacial with the respiratory and laryngeal systems was ...

Coordination and control of forces during multifingered grasping in Parkinsons disease.

In this study, we focused on how subjects with Parkinsons disease (PD) grasp and lift with five-digits of the hand. This task provided the opportunity to simultaneously examine (a) the coordination of multiple segments (i.e., digits), (b) the sequencing ...

Correlation between tests of attention and performance on grooved and Purdue pegboards in normal subjects.

This study investigated the relation between tests of manual dexterity and attentional functions with 49 normal, right-handed medical students (26 women, 23 men, ages 19-30 years) who were assessed with a Purdue Pegboard Test, Grooved Pegboard Test, and ...

Physical activity, motor ability, and school readiness of 6-yr.-old children.

The aim of this investigation was to study the relationships between physical activity, motor ability, and school readiness in 6-yr.-old children. In total, 294 healthy children from Tartu were studied (161 boys and 133 girls). The physical activity of ...

Coordination between breathing and mental grouping of pianistic finger movements.

6 pianists (age 22 to 43 years) performed a simple finger exercise at a spontaneously chosen most comfortable tempo on a Yamaha-Disklavier piano. Five versions of the exercise, notated in quarter notes, were presented with different types of meters: (1) ...

Concurrent validity of the scale for screening of developmental delay.

This study establishes the concurrent validity of the Screening Scale of Developmental Delay II (SSDD-II) with the Bayley Scale of Infant Development II (BSID-II). Three hundred and seventy-nine children referred by pediatricians at the Clinic of ...

Development of force control and timing in a finger-tapping sequence with an attenuated-force tap.

We conducted an experiment to examine age-related differences in the control of force and timing in a finger-tapping sequence with an attenuated-force tap. Participants between 7 and 20 years old tapped on a load cell with feedback on practice trials. ...
