Abstract
The aim of this investigation was to examine the correlation between unimanual and bimanual capacities as well as the perceived bimanual performance among children diagnosed with unilateral cerebral palsy (CP), aged between 6 and 12 years. A total of 34 children, consisting of 15 girls and 19 boys with a mean age of 9.47±1.62 years, participated. The Box and Block Test to quantify the unimanual capacity of both hands and the placing and turning tests, which are subtests of the Minnesota Manual Dexterity Test (MMDT), to evaluate unimanual and bimanual capacities, respectively, were used. Parents evaluated perceived bimanual performance through the Children's Hand-Use Experience Questionnaire (CHEQ) and ABILHAND-Kids. The capacity of the affected hand was found to be significantly correlated with the CHEQ subscales at a low to moderate level (R2 = 15-35%) and with ABILHAND-Kids at a low level (R2 = 16-17%). Bimanual capacity demonstrated a significant correlation ranging from low to moderate with the CHEQ subscales (R2 = 15-33%), and exhibited a weak correlation with ABILHAND-Kids (R2 = 13%). It was observed that the capacity of the contralateral hand, as measured by the MMDT placing test, exhibited a low level of significant correlation with the CHEQ subscale feeling bothered. The results indicated that the affected hand capacity and bimanual capacity had a low to moderate relationship with perceived bimanual performance. Furthermore, the predictability of perceived bimanual performance by the affected hand capacity and bimanual capacity was low.
