Afferent sensory information is important for maintaining postural stability. However, limb amputation permanently removes afferent sensory information from the amputated limb. This study provided vibratory feedback from force sensors under the prosthetic foot to transtibial prosthesis users. The results indicate that the device may not improve all measures of postural stability and that certain postural control mechanisms respond more positively than others.
