NCT03965663

Brief Summary

The aim of the study is to investigate the influence of a vibro-tactile device on trans-tibial amputees in terms of gait, pain and perception of the prosthesis.

Outcome Measures

Primary Outcomes (1)

  • Trinity Amputation and Prosthesis Experience Scales-Revised (TAPES-R)

    The Trinity Amputation and Prosthesis Experience Scales-Revised (TAPES-R) is a multidimensional instrument designed to examine the psychosocial processes involved in adjusting to amputation and a prosthesis. TAPES consists of 9 subscales, with possible scores depending on the single subscale. The range is from 0-12 to 0-25 (depending on the number of items and answer possibilities).

Secondary Outcomes (6)

  • Fall Efficacy Scale International Version (FES-I)

  • Pain Visual analoge scale (VAS)

  • Number of falls within the last two months

Study Arms (2)

Trans-tibial Amputees

EXPERIMENTAL

Unilateral Trans-tibial Amputees that use vibro-tactile feedback for six months in daily living

Device: Vibro-tactile Feedback

Trans-tibial Amputees with TSR

EXPERIMENTAL

Unilateral Trans-tibial Amputees that use vibro-tactile feedback for six months in daily living. The subjects underwent a functional nerv-transfer surgery prior to participation, where the proximal part of the sural nerv was to the distal part of the saphenous nerv.

Device: Vibro-tactile Feedback

Interventions

The device measures the force between the prosthetic food and the ground. With this signals, vibratators are triggered. The vibrators are housed by the prosthetic socket and stimulate the stump.
