Conclusions: The results suggest that auditory input is not neutral in motor skills and the complex interaction between them is generated in the earlier stages of childhood development.
Objective: The assessment of gait performance in pre-lingual deaf children with cochlear implant (CI).
Methods: Gait velocity (GV), using a 10-meter test, was measured by means of three inertial sensors in 10 pre-lingual cochlear implant users (CIU) (10–16 years old) in three sensory conditions: (1) cochlear implant turned on with environmental noise (EN), (2) cochlear implant turned on with EN and with cognitive dual task (DT), and (3) CI turned off (CI-OFF). GV with EN and DT was assessed in a normal hearing control group (CG) (n = 14). Mann-Whitney and Wilcoxon Signed ranked test were used for significance validation.
Results: (1) GV in CG was lower in DT than with EN (p= 0.019). (2) GV was faster in CG with EN compared with the three conditions in CIU (EN, p= 0.006; DT, p= 0.0001; CI-OFF, p= 0.03). (3) CIU had slower GV walking with EN (p=0.037) and with DT (p=0.022). (4) Dividing the CIU sample by age, the acoustic information generates a slower gait for those implanted after 3 years old.
