Cognitive Vs Multisensory Intervention

Better Essays

This study examines the effectiveness of cognitive versus multisensory interventions in improving handwriting legibility of children in the first and second grade who were referred for school-based occupational therapy. Two findings would impact school based occupational therapists’ practice, and these findings well reflect the development theory and the motor learning theory.

The first finding indicates that first-graders improved in handwriting performance whether they did or did not receive any intervention. This finding suggests that the regular classroom instruction was as effective as direct individual intervention, and the benefit of direct intervention may relate more to the extra practice received. Thus, direct OT intervention may …show more content…

Although more research is needed to confirm or refute the finding that the fist-graders improved their legibility with or without intervention, this study provides the evidence that direct occupational therapy intervention may not be necessary while students are still receiving instruction and learning how to print. Additional practice may be all that is required to support development of legible handwriting for these students. On the contrast, the second-grade students with handwriting difficulties require intervention to improve legibility, and the cognitive approach show greater promise versus sensory approach. I can share these evidences to teachers who attends the handwriting training session and the results can affect the incoming referrals that are requesting OT intervention. Furthermore, I can share the details of cognitive intervention as outlined by this study and collaborate with teachers to improve their knowledge and skills in helping students with handwriting …show more content…

ANOVA of change scores indicated that there was no significant difference between the first-grade and the second-grade students across the groups (F [2, 66] = 2.69, not significant; h2 = .08). All first-grade students obtained a higher legibility score at posttest than at pretest, including control group participants.
2. For the second grade students, there was a large effect size between the change scores for the cognitive versus the multisensory intervention group (d = 1.09) and the control group (d = .92). The large effect size detects a clinical change.
3. All second-grade students in the cognitive intervention group obtained higher legibility scores at posttest, whereas 4 out of 9 students in the multisensory group and 3 out of 10 students in the control group had lower legibility scores at posttest.

Comment:
This study used a large effect size in their sample size calculation. They calculated the required total sample size for an analysis of variance (ANOVA) with an alpha value of 0.05 and power at 80% to be 66, or 22 participants in each group. The actual sample size for this study is 72, or 24 participants per
