“…Recent technological advances would provide the possibility to examine motor planning and execution while manipulating everyday objects in naturalistic situations (Allievi, Arichi, Gordon, & Burdet, 2014; Campolo, Laschi, Keller, & Guglielmelli, 2007; Campolo et al, 2012; Cecchi, Serio, Del Maestro, Laschi, & Dario, 2010). For example, Campolo, Laschi, Keller, and Guglielmelli (2007) developed instrumented toys (e.g., a ball, babies rattle, toy blocks) that were equipped with kinematic (via triaxial accelerometer, triaxial magnetometer, and triaxial gyroscope) and fingertip force sensors (Quantum Tunneling Composites) capable of accurately and quantitatively measuring manual function and motor development during a block rotation and fitting task in normally developing toddlers between 12 and 36 months of age.…”

This experiment examined how multiple planning constraints affect grasp posture planning in 6-to 10-year-old children (n ϭ 16 in each group) by manipulating the intended object end-orientation (left end-down, right end-down) and initial precision demands (standard, initial precision) of a bar transport task. Results indicated that grasp posture planning was strongly influenced by multiple planning constraints. During the standard condition the sensitivity toward comfortable final hand postures (end-state comfort) was similar for all age groups in right end-down trials, and corresponded to values reported in adult populations. In contrast, there was an age-related increase in end-state comfort compliance during left end-down trials. During the initial precision condition end-state comfort was similar across all groups for left end-down trials. However, end-state comfort compliance was significantly lower for the 6-year-old children than in all other age groups for right end-down trials. In sum, the ability of children to plan their goal-related movements is influenced by the presence of task-related constraints that increase the overall cognitive demands of the task. The demands associated with selecting the appropriate grasp posture during the most cognitive demanding condition required more cognitive resources than 6-to 10-year-old children possess. Removing the conflict between the goal-directed and habitual systems reduces some of these costs, with data indicating that the ability to integrate multiple planning constraints first emerges at 7 years of age, and improves over the developmental spectrum.

“…With this in mind, another direction consists of instrumenting toys with sensors, enabling assessment as well as a game-like interface, similar to rehabilitation robots (though without the capability to move a child’s limbs). Early studies summarized in Table 1 have created such “intelligent toys” from familiar toys equipped with light-weight sensors ( 28 – 31 ), that encourage play through goal-orientated activity with regular positive feedback ( 29 , 32 – 35 ). In general, these studies have demonstrated only the feasibility of intelligent toys to derive quantitative movement measures in healthy young infants.…”

“…An instrumented sorting block toy was shown to be sufficiently sensitive to demonstrate differences in performance related to motor planning and task difficulty ( 31 ). This concept has also been extended further for babies by integrating intelligent toys into a baby gym, providing an engaging and involving enriched environment for an ecological assessment of reaching patterns and grasping forces in infants aged between 4 and 9 months ( 32 , 34 , 35 ). Longitudinal trials have demonstrated that this system is capable of providing quantitative measures of power grip maturation patterns in healthy infant subjects, and has the potential to be employed to objectively assess hand function in this naturally uncooperative population ( 34 , 36 ).…”

Technology-Aided Assessment of Sensorimotor Function in Early Infancy

There is a pressing need for new techniques capable of providing accurate information about sensorimotor function during the first 2 years of childhood. Here, we review current clinical methods and challenges for assessing motor function in early infancy, and discuss the potential benefits of applying technology-assisted methods. We also describe how the use of these tools with neuroimaging, and in particular functional magnetic resonance imaging (fMRI), can shed new light on the intra-cerebral processes underlying neurodevelopmental impairment. This knowledge is of particular relevance in the early infant brain, which has an increased capacity for compensatory neural plasticity. Such tools could bring a wealth of knowledge about the underlying pathophysiological processes of diseases such as cerebral palsy; act as biomarkers to monitor the effects of possible therapeutic interventions; and provide clinicians with much needed early diagnostic information.

“…For the past near-decade, the greater part of infant neuromotor sensing technology research has focused on detecting and analyzing patterns of movement, measuring, and modeling the same phenomena as the GMA. 16 , 17 , 18 , 19 , 20 , 21 , 22 The CareToy EU Project that produced an “intelligent baby gym” for home use with infants at risk for neurodevelopmental disorders is the most extensive example of this line of research and development. 18 , 19 , 23 , 24 …”
