"When development along any line is restricted, delayed, or distorted, other lines of development are adversely affected as well.” (1)
Restricted experiences and mobility during early childhood can have a diffuse and lasting influence. Long term physical restrictions during infancy or early childhood can significantly alter and disrupt the entire subsequent course of emotional or psychological development in the involved child (2).
Such deprivation of physical and social contingencies can lead to secondary developmental problems, including limiting motivation to explore the environment. This motivation effect is termed learned helplessness, a condition in which the child gives up trying to control his or her own world because of motor disability and diminished expectations of caregivers (3). Butler (1998) also found that children whose mobility is limited during early childhood develop a pattern of apathetic behaviors—specifically a lack of curiosity and initiative. In essence, being deprived of the experience of self-initiated mobility may keep these children dependent.
Sound empirical evidence demonstrates that children with disabilities using mobility devices became less dependent on controlling their environment using verbal commands, more interested in the environment and peer interaction (4). By providing a means for self-initiated mobility we are fostering a sense of independence and curiosity. The longer a child is without self-initiated mobility the more profoundly cognitive, social, language and motor skills will be delayed. In other words, if we provide mobility to a young child we may prevent the range of deficits that come with the lack of mobility experience noted above. But if we are considering a 2-year-old that has not had self-initiated mobility we will see a greater array of challenges and difficulties since their lack of control and independence may have led to apathy. Based on this alone, we understand that a trial of the device should start as early as 12 months of age.
Since the evidence supports that children are less dependent when provided with self-initiated mobility, what are the pre-requisite skills for a young child to trial the Explorer Mini? We know that this device was designed for children who have limited, or no mobility and the device has incorporated the postural support required not only for safety, but to promote freedom of movement, trunk and head control and hands coming to midline. Since the Explorer Mini is the only device of its kind, we don’t have the data to provide specific pre-requisites for use. But we do know what happens with extended periods of immobility for these children. Allowing infants as young as 12 months to trial the Explorer Mini may prevent the learned helplessness and loss of curiosity that can occur with children who have been immobile. Be proactive in providing every opportunity for an infant to achieve self-initiated mobility and contact us here for a trial.
