The purpose of this study was to determine the effect of simultaneous lexical-semantic retrieval on parameters of gait in younger and older healthy adults. This simultaneous cognitive-linguistic loading has implications for alterations in ambulation and gait and has been related to risk for injurious falls in both normal and clinical populations with movement disorders. Two groups were compared; twenty healthy young (aged 20-40) and 20 healthy older (aged 50+) individuals, balanced for gender, with no reported history of communication, language, cognitive, physical and neurological movement disorders, participated in this study. Participants walked across a 16 foot mat while verbally retrieving members or exemplars of a given semantic category. This task of lexical semantic retrieval also has been called generative naming or verbal fluency. The GAITRite Walkway System was used to record gait measurements and generate a Functional Ambulation Profile (FAP) score. The FAP score ranges from 0 to 100; the lower the score, the higher the risks for a serious fall with performance between 95 and 100 considered within normal limits. Participants performed three trials of walks; first, a baseline of walking with no speaking; second, walking while naming types of precious stones aloud; and third, naming types of diseases aloud. FAP scores, accuracy of responses and total number of responses were recorded and were compared across the two age groups. Results showed that the younger group had higher average FAP scores across all walking and talking conditions compared to the older group. Indicating that the older group had increased difficulty performing the speaking task while maintaining a safe gait. The differences were not significant when comparing age groups, however the significant differences in FAP scores within groups was exceptional. Thus, backing up previous research indicating that a medium or difficult lexical-semantic load can adversely impact gait and increase the risk for experiencing a fall.
