(1) The fine details of the motor organization of the forelimb, face, and tongue representation of the baboon (Papio h. anubis) primary motor cortex were studied in four adult animals, using intracortical microstimulation (ICMS). (2) A total of 293 electrode penetrations were made. ICMS was delivered to 10,052 sites, and of these, 6,186 sites were verified(More)
BACKGROUND There is growing evidence of the involvement of executive control in the maintenance of balance in old age. We examined whether healthy older adults who completed five sessions of nonmotor cognitive dual-task training would show significant improvements on measures of dual-task standing balance and mobility, compared with an untrained control(More)
Sensori-motor development and performance of daily living skills (DLS) remain little explored in children with autism spectrum disorders (ASD). The objective of this study was to determine the impact of sensori-motor skills on the performance of DLS in preschool children with ASD. Thirty-five children, 3-4 years of age, were recruited and assessed with a(More)
OBJECTIVES To determine whether tango dancing is as effective as mindfulness meditation in reducing symptoms of psychological stress, anxiety and depression, and in promoting well-being. DESIGN This study employed analysis of covariance (ANCOVA) and multiple regression analysis. PARTICIPANTS Ninety-seven people with self-declared depression were(More)
This study investigated how the dancer's level of expertise and the type of auditory guidance provided influence the kinematic profile of the lower limbs during traditional dance performance. Ten experts in traditional Greek dance (age: 25±3.29 years, five males and five females) and eleven novice participants (age: 26.45±3.88 years, six males and five(More)
When adults reach to grasp stationary targets, movement kinematics (endpoint trajectories, interjoint coordination) are highly stereotyped and stable. The emergence of an optimal coordination for reaching involves mastering the redundant number of degrees of freedom while the body grows. Reaching has been well studied in healthy children under the age of 3(More)
This study investigated the modulation of prelanding muscle activity with normal or perturbed vision under conditions where jump height was known or unknown. Lower leg electromyography (EMG) was monitored while subjects jumped from a constant (0.45 m) or variable (0.35-0.55 m) heights when vision was unaltered or perturbed by a strobe light, blackened(More)
A motor performance which involves multijoint coordination and belongs to the natural repertoire of motor behavior has been studied. Displacements have been related to EMG in the lower limb when taking off and landing from a jump down (45 cm) onto two surfaces of differing compliance in two populations of teenage girls: skilled and unskilled. To evaluate(More)
Prelanding EMG responses in elbow flexors and extensors were assessed during landing from jump-downs (0.6, 0.8, and 1.0 m) in normal blindfolded cats and labyrinthectomized cats with and without vision occluded. Jump-down conditions determined the strategy of response elicited in the normal cat. When the height could be anticipated by the blindfolded(More)
Forces and displacements at the elbow joint have been related to EMG responses of flexor and extensor muscles during landing from jump downs at heights of 1.2 m to 0.6 m in five cats. Prelanding EMG activity consisted of two prelanding extensor bursts. Onset of both bursts was constant across all jump heights with reference to landing and not to take-off,(More)
