“…This was evidenced in the CP youth having lower percentages of postural muscle bursting activity in the posterior muscles. While there were no differences observed in the tibialis anterior and quadriceps between CP and TD groups, this may be a result of leaning forward to counteract the movement of the platform and allow the inertia of the body to return the center of mass to a stable position [20]. Previous research has also established youth with CP to have poorly organized muscle activation [11,32].…”

Higher frequency platform movements proved more difficult for youth with CP, however, like TD youth, they shifted from reactive to anticipatory mechanisms when the platform frequency remained constant by taking advantage of knowledge of platform movement. When given control over perturbation onset, further evidence of anticipatory mechanisms was observed following the transition to a new oscillation frequency.

“…Specifically, changes in movement perception may be indicative of the recalibration of our predictive internal models, which associate our motor commands with their expected perceptual consequences. Data from several groups suggest that internal models are not yet fully developed in school-aged children 38–40 , especially for complex tasks requiring balance 41 , such as walking. More specifically, the association between an action and its sensory consequences may not be recalibrated as flexibly in children as in adults 42 .…”

Learning new movements through an error-based process called motor adaptation is thought to involve multiple mechanisms which are still largely not understood. Previous studies have shown that young children adapt movement more slowly than adults, perhaps supporting the involvement of distinct neural circuits that come online at different stages of development. Recent studies in adults have shown that in addition to recalibrating a movement, motor adaptation also leads to changes in the perception of that movement. However, we do not yet understand the relationship between the processes that underlie motor and perceptual recalibration. Here we studied motor and perceptual recalibration with split-belt walking adaptation in adults and children aged 6–8 years. Consistent with previous work, we found that this group of children adapted their walking patterns more slowly than adults, though individual children ranged from slow to adult-like in their adaptation rates. Perceptual recalibration was also reduced in the same group of children compared to adults, with individual children ranging from having no recalibration to having adult–like recalibration. In sum, faster motor adaptation and the ability to recalibrate movement perception both come online within a similar age-range, raising the possibility that the same sensorimotor mechanisms underlie these processes.

“…Essentially, adolescents may have a diminished ability to detect errors in their selected motor actions because their interpretation of the sensory feedback is less precise and delayed 8,9,13–16 . Alternatively, other investigations have hypothesized that the motor control differences may not be related to the quality of the sensory feedback, but rather adolescents are less experienced at properly weighting all of the available sensory feedback during a movement ( i.e .., muscle spindle, joint position, visual tracking) 10–12 . While both of these hypotheses are plausible, limited efforts have been made to determine if there is a connection between the somatosensory cortical processing and the motor actions seen in adolescents.…”

Adolescents demonstrate increasing mastery of motor actions with age. One prevailing hypothesis is that maturation of the somatosensory system during adolescence contributes to the improved motor control. However, limited efforts have been made to determine if somatosensory cortical processing is different in adolescents during movement. In this study, we used magnetoencephalographic brain imaging to begin addressing this knowledge gap by applying an electrical stimulation to the tibial nerve as adolescents (Age = 14.8 ± 2.5 yrs.) and adults (Age = 36.8 ± 5.0 yrs.) produced an isometric ankle plantarflexion force, or sat with no motor activity. Our results showed strong somatosensory cortical oscillations for both conditions in the alpha-beta (8–30 Hz) and gamma (38–80 Hz) ranges that occurred immediately after the stimulation (0–125 ms), and a beta (18–26 Hz) oscillatory response shortly thereafter (300–400 ms). Compared with the passive condition, all of these frequency specific cortical oscillations were attenuated while producing the ankle force. The attenuation of the alpha-beta response was greater in adolescents, while the adults had a greater attenuation of the beta response. These results imply that altered attenuation of the somatosensory cortical oscillations might be central to the under-developed somatosensory processing and motor performance characteristics in adolescents.
