Use of Subtle Vibration to Improve Walking Ability by Lower Limb Amputees

NCT00985881 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 17

Last updated 2018-06-29

No results posted yet for this study

Summary

The purpose of this study is to determine if subthreshold vibration, when applied to the residual limb of a lower limb amputee through their prosthetic socket, can sufficiently enhance peripheral sensation to result in an improved ability to balance and walk.

Conditions

  • Amputation
  • Diabetes Complications

Interventions

DEVICE

Custom prosthetic socket with mechanical vibrators (stochastic resonance)

Application of mechanically-induced sub-threshold vibration applied to the amputee's residual limb using a custom prosthetic limb system

DEVICE

Conventional prosthetic socket (current clinical practice)

No sub-threshold vibration applied to residual limb. Amputee wears conventional prosthetic socket.
