“…The primary goal of this investigation was to provide further insight on the neural basis for the hand tactile sensory deficits often reported in the clinic for children with CP (Cooper et al, 1995; Clayton et al, 2003; Sanger and Kukke, 2007; Wingert et al, 2007; Auld et al, 2012; Robert et al, 2013). To this end, we used high-density MEG to identify the alpha-theta and beta oscillatory differences between children with CP and TD children in the somatosensory cortices following tactile stimulation of the hand.…”

“…However, the reclassification of CP now includes other characteristics such as sensation, and perception deficits that may arise from the primary insult or secondarily from restricted perception-action experiences (Rosenbaum et al, 2007). The inclusion of sensory deficits in the updated classification of CP has been supported by numerous clinical reports of proprioception, stereognosis and tactile discrimination deficits in these children (Cooper et al, 1995; Clayton et al, 2003; Sanger and Kukke, 2007; Wingert et al, 2007; Auld et al, 2012; Robert et al, 2013). …”

“…It is now well appreciated that many children with CP lack the ability to properly register and discriminate different tactile stimuli that are provided to the hand mechanoreceptors (Cooper et al, 1995; Clayton et al, 2003; Sanger and Kukke, 2007; Wingert et al, 2007; Auld et al, 2012; Robert et al, 2013). Furthermore, it has been shown that theses tactile discrimination deficits likely impact the child’s ability to properly plan and control their grip forces (Gordon and Duff, 1999; Auld et al, 2012).…”

Children with cerebral palsy have uncharacteristic somatosensory cortical oscillations after stimulation of the hand mechanoreceptors

Numerous clinical investigations have reported that children with cerebral palsy (CP) have tactile discrimination deficits that likely limit their ability to plan and manipulate objects. Despite this clinical awareness, we still have a substantial knowledge gap in our understanding of the neurological basis for these tactile discrimination deficits. Previously, we have shown that children with CP have aberrant alpha-theta (4–14 Hz) oscillations in the somatosensory cortices following tactile stimulation of the foot. In this investigation, we evaluated if these aberrant alpha-theta oscillations also extend to the hand. Magnetoencephalography was used to evaluate event-related changes in the alpha-theta and beta (18–34 Hz) somatosensory cortical oscillations in groups of children with CP and typically developing (TD) children following tactile stimulation of their hands. Our results showed that the somatosensory alpha-theta oscillations were relatively intact in the children with CP, which is in contrast to our previous results for foot tactile stimulations. We suspect that these inter-study differences may be related to the higher probability that the neural tracts serving the lower extremities are damaged in children with CP, compared to those serving the upper extremities. This inference is plausible since the participating children with CP had Manual Ability Classification System (MACS) levels between I-II. In contrast to the alpha-theta results, the children with CP did exhibit a sharp increase in beta activity during the same time period, which was not observed in TD children. This suggests that the children with CP still have deficits in the computational aspect of somatosensory processing.

“…Typical development is underpinned by an intact somatosensory system with unimpaired functioning of touch, proprioception and haptic ability (Royeen & Lane, ; Pehoski, ). Typical functional somatosensation provides a benchmark against which to compare clinical populations who are known to experience somatosensory deficits in the hands (Cooper et al , ; Clayton, ; Auld et al , ). From current literature we know that between 31 and 97% of children with cerebral palsy assessed experienced deficits in touch registration, proprioception and/or touch perception and stereognosis (Cooper et al , ; Wingert et al , ; Auld et al , ).…”

Does somatosensation change with age in children and adolescents? A systematic review

Somatosensation matures through childhood into adolescence; however, the present review found the pattern of somatosensory development varied depending on the assessment tool used and the aspect of somatosensation being measured, making it difficult to describe typical performance. There is a need for comprehensive assessment batteries to measure the somatosensation, including touch, proprioception and haptic ability, of children at risk of somatosensory impairment to aid in the development of effective interventions.

“…However, in some cases, the corticospinal tracts in the lesioned (contralateral to the affected hand) hemisphere are sustained, even with very little remaining white matter (Staudt et al, ). In addition to motor problems, tactile discrimination deficits are prevalent in individuals with CP (for a review see Clayton et al, ). In contrast to the motor system, the somatosensory representation remains in the lesioned hemisphere (i.e., contralateral to the affected hand) (Gerloff et al, ; Staudt et al, ; Wilke et al, ).…”

Cerebral palsy (CP) is characterized by difficulty in control of movement and posture due to brain damage during early development. In addition, tactile discrimination deficits are prevalent in CP. To study the function of somatosensory and motor systems in CP, we compared the reactivity of sensorimotor cortical oscillations to median nerve stimulation in 12 hemiplegic CP children vs. 12 typically developing children using magnetoencephalography. We also determined the primary cortical somatosensory and motor representation areas of the affected hand in the CP children using somatosensory-evoked magnetic fields and navigated transcranial magnetic stimulation, respectively. We hypothesized that the reactivity of the sensorimotor oscillations in alpha (10 Hz) and beta (20 Hz) bands would be altered in CP and that the beta-band reactivity would depend on the individual pattern of motor representation. Accordingly, in children with CP, suppression and rebound of both oscillations after stimulation of the contralateral hand were smaller in the lesioned than intact hemisphere. Furthermore, in two of the three children with CP having ipsilateral motor representation, the beta- but not alpha-band modulations were absent in both hemispheres after affected hand stimulation suggesting abnormal sensorimotor network interactions in these individuals. The results are consistent with widespread alterations in information processing in the sensorimotor system and complement current understanding of sensorimotor network development after early brain insults. Precise knowledge of the functional sensorimotor network organization may be useful in tailoring individual rehabilitation for people with CP.
