This study was designed to investigate the developmental progression in pencil and crayon grip. The subjects were 320 nondysfunctional children aged 3.0 to 6.11 years, with 20 boys and 20 girls at each 6-month age interval. On the basis of a review of the literature, developmental pencil and crayon grips were defined for the study, and the type of grips each child used to perform a drawing task and a coloring task were recorded. Many children at each age level used mature pencil grips. A developmental progression, however, was shown by the percentage change of children at each age level who used mature grips. Forty-eight percent of the youngest group used mature grips, compared with 90% of the oldest children. Two pencil grips-dynamic and lateral tripod-appear to be common in older children. Differences in the developmental progression of pencil grip were noted between boys and girls and between a drawing task and a coloring task.

The aim of this study was to investigate the relationship between motor performance, attention deficit, impulsiveness, and hyperactivity in children with attention-deficit--hyperactivity disorder (ADHD). Participants were 42 school-aged children with ADHD (36 males, 6 females; mean age 8 years 2 months, SD 1 year 2 months; range 6 years to 11 years), and 42 age- and sex-matched children without ADHD (mean age 8 years 3 months, SD 1 year 1 month; range 6 years to 11 years). Motor abilities were assessed with the Bruininks-Oseretsky Test of Motor Proficiency. Attention and impulse control were measured with the Gordon Diagnostic System, and assessment of activity level was based on two Activity Level Rating Scales that were completed by parents and teachers. Analysis by t-test revealed a significant difference between children with and without ADHD in fine and gross motor skills, impulse control, and attention. Stepwise regression indicated that attention, impulse control, and parent ratings of activity level were the three best predictors of gross motor skills for children with ADHD, accounting for 55.9% of the variance. Attention and impulse control were the two best predictors of fine motor skills, accounting for 45.7% of the variance. Attention and impulse control were consistently found to be important predictors of both fine and gross motor skills in children with ADHD. However, the fact that activity level was a predictor for gross motor proficiency but not for fine motor tasks suggests that different behavioral processes are involved in fine and gross motor performance to different extents.

The higher mean percent of time spent in fine motor activities in kindergarten classrooms suggests a developmentally appropriate increase in fine motor demands. The percent of paper and pencil activity time the children engaged in substantially increased from Head Start to kindergarten. The findings describe a difference between the two environments, informing Head Start of the fine motor demands their graduates face in kindergarten.

The development of in-hand manipulation skills of rotation involves improvement in the dimension of speed, method, and consistency. Observation of these skills in a child can add to a therapist's understanding of the child's fine motor abilities. The variability in children's performance needs to be considered in both evaluation and treatment planning.

This investigation was designed to gather descriptive data on the clinical practice patterns of occupational therapists working with infants and young children. One hundred nineteen therapists entered the study, and 118 completed the interview, yielding a response rate of 99.4%. The therapists were highly experienced, with a mean of 9.47 years working in pediatrics. The school setting was the most common type of facility in which therapists served infants and young children and accounted for 37.3% of the sample. The majority of the respondents (67.8%) were members of formally identified teams. Although 80.5% of the therapists served very young children (aged birth to 12 months), no therapists served this population exclusively. Considerable variability in models of service provision, team structures, and assessment and treatment practices were found. Additionally, there was a lack of consensus on the unique contributions of occupational therapy and diverse opinions regarding the importance of selected frames of reference. Implications of the findings on professional initiatives to enhance practice are discussed.
