Figure 5. Summary of the effects of each type of skin stimulation.

Grouped data for illusory movement amplitudes evoked by combined skin stimulation and vibration over the finger extensors, normalised to the corresponding amplitudes evoked by vibration alone. Data are grouped according to the proximity to the region of stimulated skin. Data are shown for skin stretch on the dorsal side of the MCP joint (•), skin stretch on the dorsal and ventral sides of the hand (⋄), electrical stimulation on the dorsal side of the MCP joint (▵), and electrical stimulation at the distal phalanx (▪).
