Correlation of Motor Function and Stereognosis Impairment in Upper Limb Cerebral Palsy

Stability of stereognosis after pediatric repetitive transcranial magnetic stimulation and constraint-induced movement therapy clinical trial

“…Scores are reported as the number of objects correctly identified without the use of vision. 20 Methodology used for testing is described in Supplemental Materials.…”

“…11 Significant inverse correlations between sensibility deficits and motor function exist in children with spastic hemiplegia and considerably influence unimanual hand control. 12, 13 These deficits are often not readily apparent and children will not self-identify differences in sensation due to the congenital nature of pediatric stroke.…”

Affected and Contralateral Hand Strength and Dexterity Measures in Children With Hemiplegic Cerebral Palsy

“…7,8 The child was shown and asked to name 12 objects: a wooden block, key, pencil, penny, marble, string, button, safety pin, bead, glove, spoon, and paperclip. The child placed his or her hand inside a tabletop tent and the test administrator placed an object in the tent in random order without the child seeing it.…”

“…Most commonly in spastic hemiplegia, the resting posture includes elbow flexion, forearm pronation, wrist ulnar deviation and flexion, and thumb adduction and flexion and is caused by muscle imbalance and weakness, resulting in deficits in precision grasp, pinch, and dexterity. The severity of motor impairment has been shown to correlate with sensory deficits 7 ; the greater the sensory deficit, the more likely there will be some neglect and disuse, 8 putting additional demands on the contralateral hand in activity.…”

Stump sensibility in children with upper limb reduction deficiency

“…Different modalities of sensibility exist; for instance, threshold of touch, 2-point discrimination, kinaesthesia and stereognosis are used to measure sensibility. Stereognosis plays an important role in the hand function of children with cerebral palsy (11,12). Impairments in stereognosis are correlated with motor function impairments (11).…”
