Objectivo: Avaliar a proficiência e assimetria
manual de indivíduos com Trissomia 21 (T21) em dois testes
de destreza manual: global e fina.
Métodos: Participaram 21 indivíduos com T21 entre
os 17 e os 45 anos, sendo 13 destros, residentes na cidade do
Porto, Portugal. Para a avaliação da Destreza Manual Global
(DMG) utilizou-se o Minnesota Manual Dexterity Test (versão
de colocação) e para a Destreza Manual Fina (DMF), o
PurduePegboard.
Resultados: No teste de DMF não se verificaram
diferenças estatisticamente significativas (t(20)=1.23, p=0.233)
entre as mãos; porém, no teste de DMG a diferença entre as
mãos alcançou significado estatístico (t(20)=3.128, p=0,005),
sendo a mão não preferida (145.22±53.42 seg.) mais rápida do
que a mão preferida (156.16±59.99 seg.). O Índice de
Assimetria Manual para cada uma das tarefas foi calculado,
porém, não revelou significado estatístico (t(20)=-1.003,
p=0.328).
Conclusão: A melhor proficiência com a mão não
preferida na tarefa de DMG pode estar relacionada com
características peculiares para esta população, como as
dificuldades na motricidade seletiva, o que empobreceria o
desempenho para ambas as mãos, ou ainda com outros fatores
a serem investigados. Os dados sugerem que tarefas de DMF e
DMG desempenhadas por pessoas com T21 não são
influenciadas pela preferência manual.
Objective: To evaluate the proficiency and manual asymmetry of individuals with Trisomy 21 (T21) in two manual dexterity tests: global and fine. Methods: Participants were 21 individuals with T21 between 17 and 45 years, 13 right-handed, residents in the city of Porto, Portugal. For evaluating the overall handedness (DMG) we used the Minnesota Manual Dexterity Test (placement version) and for fine manual dexterity (DMF), the Purdue Pegboard.Results: In DMF test statistically significant differences were not observed (t (20) = 1.23, p = 0.233) between the hands, but in the DMG test the difference between hands reach statistical significance (t (20) = 3.128, p = 0.005), not being the preferred hand (145.22 sec ± 53.42) faster than the preferred hand (156.16 sec ± 59.99). The Asymmetry Index Manual for each task was conducted, however, did not reveal statistically significant (t (20) = - 1.003, p = 0.328). Conclusion: The best proficiency with the hand not preferred in DMG task may be related to peculiar characteristics to this population, such as difficulties in selective motor, which impoverish the performance for either hand, or with other factors to be investigated. The data suggest that the task performed by DMG and DMF and people with T21 are not influenced by manual preference.
