Purpose: To compare functioning and environmental aspects before and during physical distancing (DPD) and to determine which social, physical, behavioral and functioning aspects of DPD are correlated. Methods: Sixteen parents of children/adolescents with Down syndrome (11.38 ± 3.00 years) were surveyed before and DPD. Paired t-tests were used to compare functioning and environmental aspects before and DPD and chi-square tests were used to test associations. Results: There were increases in the frequency (p < 0.001) and involvement (p = 0.01) in home participation and on the impact, noticed by the parents, of the possibility of child to participate in daily activities (p = 0.036), as well as a reduction in social supports perceived by caregivers (p = 0.049). An association was found between the child's socio-emotional difficulties symptoms and practice of physical activity (p = 0.043) and with parents' satisfaction with the level of child's home participation (p = 0.042). Conclusion: Functioning can be affected in either positive or negative ways.

During infant development, objects and their functions are learned by means of active exploration. Factors that may influence exploration include reaching and grasping ability, object properties and the presence of developmental disorders. We assessed the development of exploratory actions in 16 typically-developing (TD) infants and 9 infants with Down syndrome (DS) after reaching onset. Infants with DS reached for and explored objects less frequently than TD infants, especially small objects. Over time, the amount of reaches increased in both groups, with no changes in the amount of exploration in the DS group. Pre-grasping actions were different across objects, but less efficient in generating action-relevant information in the DS group. These infants also performed fewer behaviors requiring complex motor skills. The results suggest that perceptual-motor abilities determine different exploratory behaviors in TD and DS infants. The reduced amount and complexity of exploratory actions may impact developmental outcome in DS. (Contains 1 table and 2 figures.)

Reaching and grasping skills have been described to emerge from a dynamic interaction between intrinsic and extrinsic factors. The purpose of the present study was to investigate the interaction between such an intrinsic factor, Down syndrome, and extrinsic factors, such as different object properties. Seven infants with Down syndrome and seven infants with typical development were assessed at the ages of 4, 5 and 6 months. The findings showed that object size influenced the kinematics of reaching for the infants with Down syndrome and the grasping frequency for the typical infants. The object rigidity was shown to have a major influence on grasping frequency. (Contains 1 table and 1 figure.)

Reaching and grasping skills have been described to emerge from a dynamic interaction between intrinsic and extrinsic factors. The aims of the study were to investigate the effect of such intrinsic factors as age and Down syndrome on the development of reaching and grasping skills and on overall gross motor skill, and to test the influence of the overall level of gross motor skill on the development of reaching and grasping. Seven infants with Down syndrome (DS) and seven infants with typical development were assessed at the ages of 4, 5 and 6 months. The following variables were analyzed: straightness index, mean velocity, movement units and deceleration time (for reaching movements), grasping frequency and AIMS scores. Intrinsic factors such as age and DS were found to influence the development of reaching, grasping, and of the overall level of gross motor skill. The overall level of gross motor skill was observed to influence grasping. (Contains 4 figures.)
