Prediction of Functional Academic Outcomes by Fine Motor Skills in Individuals With Sickle Cell Disease.

The study did not include a demographically matched control group, so it is unclear how much of the fine motor deficit is due to sickle cell disease versus other environmental factors. Information about prior occupational therapy services was not available, so it is not known if previous interventions influenced the results. Other neurocognitive domains, such as processing speed, were not fully evaluated, making it difficult to isolate the specific impact of sickle cell disease on motor performance. Not all participants received neuroimaging, so the effect of silent strokes or other cerebrovascular events on fine motor function is unknown.

Do not assume that poor academic performance in these patients is solely due to cognitive impairment or lack of effort. The study shows that fine motor deficits are a significant independent predictor of poor math and reading scores, meaning that physical difficulties with writing and manipulating tools can block academic achievement even when intelligence is intact.
