Motor Skill Development of Children with HIV Infection Measured with the Peabody Developmental Motor Scales

Improved health care for pregnant women who are HIV+has minimized complications during delivery and resulted in a measurable cohort of children entering the health care system who are HIV+ with potential for motor disorders. This study was designed to determine how gross and fine motor skills were affected by HIV infection in children aged five years and younger using the Peabody Developmental Motor Scales, and to follow a subsample of these children for one and a half years to determine if their relative skill performances changed over time.

A sample of 143 children who were HIV+ was evaluated using the Peabody Developmental Motor Scales for their gross and fine motor skills. Their performance scores were compared with the Peabody normative values for age-matched healthy children. A subset of 22 children were reevaluated at six-month intervals (six months; one year;one year six months) to determine if their gross and fine motor skills would change. Raw scores and Peabody Developmental Motor Quotients (DMQ, normalized to the reference population) were calculated.

The children who were HIV+ as a group performed below the 50th percentile of the normal reference population. During the one year six month study period, the children who were HIV+improved in raw scores but did not improve in relative (DMQ) scores. The exceptions were the fine motor skill subcategories of "grasping" and "hand use," for which the children who were HIV+performed comparably with the reference population.

Clinicians working with children who are HIV+ should emphasize intervention strategies generally designed to develop all gross motor skills and the specific fine motor skills of "eye-hand coordination" and "manual dexterity."
