Duchenne muscular dystrophy
AIM To investigate tactile perception and manual dexterity, with or without visual feedback, in males with Duchenne muscular dystrophy (DMD). METHOD Forty males with DMD (mean age 9y 8mo, SD 2y 3mo; range 5–14y), recruited from ~ o Paulo, with disease the teaching hospital of the School of Medicine of the University of Sa severity graded as ‘1’ to ‘6’ on the Vignos Scale and ‘1’ on Brooke’s Scale, and 49 healthy males (mean age 8y 2mo; range 5–11y; SD 1y 11mo), recruited from a local education center, participated in the study. We assessed tactile perception using two-point discrimination and stereognosis tests, and manual dexterity using the Pick-Up test with the eyes either open or closed. Analysis of variance was used to compare groups; a p value of less than 0.05 was considered statistically significant. RESULTS Males with DMD exhibited no impairment in tactile perception, as measured by the two-point discrimination test and the number of objects correctly named in the stereognosis test. Manipulation during stereognosis was statistically slower with both hands (p
