Overview of results from qualitative analysis of video recorded Timed Up-and-Go dual task test performances and the verification protocol developed through interpretation of these results.

Mobility-	A) Observations of Deviant Performance		B) Verification Protocol (Based on A)
Sequence	Mobility	Verbal	Normal Performance	Deviant Performance
Initiation and rising up from the chair	Starts during the instructions Rises and stands still/ and asks: Shall I start at once?	Asks: Shall I start with the animals?/Shall I say it out loud?
