Dynamics of effortful touch and interlimb coordination.
In biological movement systems, the level of muscular-articular links is responsible for assembling highly reliable, stable, and reproducible coordination patterns involving very many joints and muscles. Research shows that the important perceptual capabilities of this level arise from the bulk sensitivity of muscles and tendons, so-called effortful or dynamic touch, to the quantities of rotati...
متن کاملStability of gait and interlimb coordination in older adults.
Most falls in older adults occur when walking, specifically following a trip. This study investigated the short- and longer term responses of young (n = 24, 27.6 ± 4.5 yr) and older adults (n = 18, 69.1 ± 4.2 yr) to a trip during gait at comfortable speed and the role of interlimb coordination in recovery from tripping. Subjects walked on a self-paced treadmill when forward movement of their do...
متن کاملEffect of type of attentioal instruction and increasing frequency on relative phase stability of coordination bimanual movements
Thepurpose of present research was to answer to this question that how attentionalinstructions and increasing frequency of movement impress on relative phasestability in coordination bimanual movements? Participants (N=14) practiced inphase and anti phase under internal and external attention and increasingfrequency. In acquisition phase apply external v. internal attention and aftereach trial ...
متن کاملEmergence and stability of interlimb coordination patterns in children with developmental coordination disorder.
The purpose of this study was to investigate the emergence and stability of coordination patterns in children with developmental coordination disorder (DCD) when performing a rhythmic interlimb coordination task on rigid (floor) and elastic (mini-trampoline) surfaces. Twelve typically developing (TD) children and 12 children with DCD were required to clap while jumping under different condition...
متن کاملBreaking the reflectional symmetry of interlimb coordination dynamics.
Interlimb rhythmic coordination is reflectionally symmetric when the left and right limb segments are identical in uncoupled frequencies and spatial orientation. In the present studies (4 experiments, with a total of 31 participants), when reflectional symmetry was broken through differences in timing (frequency), the resulting stable states were related by reflection and were identical for pai...
