Validez y fiabilidad del cuestionario Hand10 en niños con parálisis cerebral unilateral

The Hand10 questionnaire is used to assess upper extremity functions through 10 daily activity items and is designed for clarity with visual content that enhances comprehension. This study aimed to determine the validity, test-retest reliability, and internal consistency of the Hand10 in children with unilateral cerebral palsy (uCP).

The Hand10 was tested for validity and internal consistency with 63 children with uCP and their families, aged 6 to 15 years. Additionally, 43 children and their families were re-interviewed two weeks later to determine test-retest reliability. Concurrent validity was examined by correlating scores on Hand10 and ABILHAND-Kids.

The Hand10 was strongly correlated with ABILHAND-Kids-Total score (p < 0.001, r = 0.766). The Hand10 showed excellent test-retest reliability (ICC = 0.96, 95%CI: 0.92-0.97) and high internal consistency for the total score (α = 0.92). For all items, item-total correlations were adequate (corrected item-total correlations, 0.62-0.80). The Hand10 score showed a statistically significant difference between the Manual Ability Classification System levels (p < 0.001).

The Hand10 demonstrates excellent reliability and strong validity in assessing manual dexterity during daily activities in children with uCP.
