Safety and efficacy of vibrotactile feedback for adults with transtibial amputation: A randomized controlled cross-over trial.

Background: Pain, social integration, and walking safely with divided attention challenge people with lower-limb amputation. Tactile feedback systems aim to improve sensations and rehabilitation by facilitating prosthesis utility and embodiment. The non-invasive vibrotactile feedback device Suralis® (Saphenus Medical Technology, Vienna, Austria) aims to improve gait, postural control, and pain treatment.
