METHODS: Published literature was systematically searched according to PRISMA guidelines using specific key terms. Initial search identified 785 studies; however only seven met the inclusion criteria and were assessed for final review. Studies were methodologically appraised using the McMaster Critical Review Form-Quantitative Studies.
RESULTS: The review found no randomised control trial study design pertaining to the reviewed area. However, it can be seen that occupational therapy interventions for writing skills in 4-6 year old children managed to increase the targeted skills. The results were similar across samples with or without disabilities. An effective integration of occupational therapy interventions into educational curriculum was found to save both time and cost.
CONCLUSION: The long-term benefit from these interventions and the effects of these interventions on a broader spectrum of fine motor abilities need to be explored further with stronger research designs. However, the lack of studies adopting high level study designs, i.e., RCT designs means, results need to be approached with caution by occupational therapists when implementing handwriting skills intervention in practice.
