The ability to detect a tactile stimulus during movement is markedly decreased (e.g., tactile gating), yet it is unknown whether the stimulus influences motor output. In the present study, participants moved a mechanical slider as quickly and as accurately as possible to a target. Participants received low-level electrical stimulation on the index finger of the reaching limb at various offsets relative to movement initiation. Participants reported whether they perceived the tactile cue. It was hypothesized that the detection of the stimulus would be reduced and the stimulus would influence motor output. First, a typical time course and magnitude of sensory gating was found, supporting previous observations (e.g., Chapman & Beauchamp, 2006). Second, no influence of the stimulation on motor output was observed. It was concluded that the detection of tactile cues during a goal-directed reaching task is attenuated and this stimulation does not influence motor output
