“…the object is placed or passively moved in the hand) for object identification, and various manipulation strategies have been described in typical populations. These include use of grip to give a general impression of the object and more complex patterns of manipulation to refine analysis of the object 21 . Given that children with congenital hemiplegia have difficulties with grasp and manipulation, deficits identified in stereognosis in our study may also reflect motor impairment and explain why stereognosis was more important to bimanual performance than M2PD.…”

“…A number of children could not accurately complete the stereognosis task on their unimpaired upper limb. The ability to recognize familiar objects by touch develops earlier 21 and may explain why the majority of children with congenital hemiplegia in our study could accurately identify three familiar objects. Accuracy of recognition of more complex or unfamiliar shapes develops over time, and could explain the large number of children with congenital hemiplegia and our typically developing children (who were generally younger) who were unable to accurately identify the six paired objects.…”

AIM This study explores the relationship between unimanual capacity and bimanual performance for children with congenital hemiplegia aged 5 to 16 years. It also examines the relationship between impairments and unimanual capacity and bimanual performance.METHOD Participants in this cross-sectional study attended a screening assessment before participating in a large, randomized trial. They comprised 70 children with congenital hemiplegia (39 males, 31 females; mean age 10y 6mo, SD 3y); 18 were classified in the Manual Ability Classification System level I, 51 in level II, and one in level III. Eighteen were in Gross Motor Function Classification System, level I and 52 in level II. Sixty-five participants had spasticity and five had dystonia and spasticity. Fifteen typically developing children (7 males, 8 females; mean age 8y 8mo, SD 2y 7mo), matched to study participants for age and sex, were recruited as a comparison group for measures of sensation, grip strength, and movement efficiency. Outcome measures for unimanual capacity were the Melbourne Assessment of Unilateral Upper Limb Function (MUUL), and the Jebsen-Taylor Hand Function Test (JTHFT). The Assisting Hand Assessment (AHA) evaluated bimanual performance. Upper limb impairments were measured using assessments of stereognosis, moving two-point discrimination, spasticity, and grip strength. RESULTSThere was a strong relationship between unimanual capacity (MUUL) and bimanual performance (AHA; r=0.83). Linear regression indicated MUUL and stereognosis accounted for 75% of the variance in AHA logit scores. Sensory measures were moderately correlated with unimanual capacity and bimanual performance. Age, sex, and grip strength did not significantly influence bimanual performance. There was no difference between children with right-and left-sided hemiplegia for motor performance.

“…This was confirmed in a study that reported that typically developing school-age children performing a shape identification task showed equal success when using haptic perception (active in-hand manipulation) or pure tactile perception (the object was moved by an examiner in the hand of the child), but poorer performance when the object was merely pressed against the palm of the child's hand (Cronin, 1977). As this indicates that movement of the object across the skin surface is the key to shape identification (Cermak, 2006), reduction or variability in this information should be avoided by removing the need for in-hand manipulation when testing children who cannot move the object themselves.…”

This review evaluates the clinimetric properties of tactile assessments for children with cerebral palsy. Assessment of registration was reported using Semmes Weinstein Monofilaments (SWMs) or exteroception. Assessment of two-point discrimination was reported using the Disk-Criminator R or paperclip methods; Single point localization and double simultaneous were reported from the Neurosensory Motor Developmental Assessment (NSMDA); graphaesthesia was reported from the Sensory Integration and Praxis Test (SIPT); and stereognosis was assessed using Manual Form Perception from the SIPT and the Klingels method (Klingels, K. et al. (2010). Upper limb motor and sensory impairments in children with hemiplegic cerebral palsy. Can they be measured reliably? Disability and Rehabilitation, 32(5), 409-416) and the Cooper method (Cooper, J., Majnemer, A., Rosenblatt, B., & Birnbaum, R. (1995). The determination of sensory deficits in children with hemiplegic cerebral palsy. Journal of Child Neurology, 10,[300][301][302][303][304][305][306][307][308][309]. The SIPT and NSMDA demonstrated stronger content validity. Inter-rater reliability was excellent for SIPT (ICC = 0.99) and exteroception (k = 0.88). Test-retest reliability was excellent for exteroception (k = 0.89) and stereognosis (ICC = 0.86; 100%), moderate for SIPT (r = 0.69-0.74) and poor for SWM (k = 0.22). Together these assessments measure tactile registration and spatial perception. Temporal and textural tests are to be developed for comprehensive tactile examination.

“…In‐hand manipulation can be significantly compromised for children with neurological and musculoskeletal deficits due to CP (Eliasson et al ., ). Movement of an object across the skin by an examiner has been found to achieve success equivalent to a child performing the exploration themselves (Cermak, ). Recent studies have recommended removing the need for in‐hand manipulation when testing children who cannot move the object themselves (Auld et al .).…”
