As a result of their study, Pehoski et al. (1997) have contributed to our knowledge of the development of in-hand manipulation skills in young children. Although knowledge of skill development in children who are typically developing must be applied with caution to children with disabilities, information about normal development provides us with at least the basis for evaluation and treatment planning. Children with moderate and severe problems with hand skills are very unlikely to be appropriate candidates for intervention for in-hand manipulation skills, but children with mild disabilities may be easier for the therapist to identify when using these data on developmental trends and descriptions of strategies for execution of in-hand manipulation skills. Such identification has the potential to lead to intervention that can positively influence the child's performance of a variety of functional tasks that rely on these skills.
