Abstract Background The aim of the study was to assess the attentional requirements of steady state treadmill walking in human subjects using a dual task paradigm. The extent of decrement of a secondary cognitive RT task provides a measure of the attentional resources required to maintain performance of the primary locomotor task. Varying the level of difficulty of the reaction time RT task is used to verify the priority of allocation of attentional resources. Methods 1 1 healthy adult subjects were required to walk while simultaneously performing a RT task. Participants were instructed to bite a pressure transducer placed in the mouth as quickly as possible in response to an unpredictable electrical stimulation applied on the back of the
