Invasive peripheral nerve interfaces have demonstrated the value of restored touch perceptions in the missing hand elicited by electrical stimulation after arm amputation. However, invasive interfaces may not be the preferred option for many prosthesis users. We explored the use of non-invasive mechanical stimulation, targeted transcutaneous electrical nerve stimulation (tTENS), and thermal stimulation of naturally occurring reinnervated nerve sites in the residual limb to restore multiple modalities of touch in the phantom hand. In two individuals with arm amputation, we reported tactile sensations of pressure, elicited by mechanical stimulation and tTENS, and cooling, elicited by thermal stimulation, in the phantom hand. Tactile perceptions and stimulation locations remained stable over multiple years. We observed that the activated regions of the phantom hand may by stimulation modality specific, in that tactile sensations did not always overlap when different stimulation modalities were used at the same location on the residual limb. These results may be useful in helping restore a broad range of touch feedback for prosthesis users through non-invasive stimulation approaches.
