Tactile hypersensitivity is a common sequela of traumatic hand injury. Vibration is used clinically to reduce this hypersensitivity. The purpose of this study was to determine if vibration has an effect on tactile threshold and if so to determine the duration of that effect. ⋯ No significant change in mean tactile threshold was found in the control group. The results indicate that vibration does increase tactile threshold in "normal" hands and the effect lasts for at least 10 minutes. The application of this information to the clinical setting is discussed.
