Whole‐Body Vibration Without Visual Feedback on Postural Steadiness in Unilateral <i>Trans</i>‐Femoral Traumatic Amputees: A Randomized Controlled Trial

Abstract

BACKGROUND: Unilateral traumatic trans-femoral amputees exhibit a higher incidence of falling and become physically asymmetrical because the side that was amputated has different feelings and less muscle. OBJECTIVES: To explore the impact of Whole-body vibration Without Visual Feedback (VFDWBV) on postural steadiness in unilateral traumatic trans- femoral amputees. METHODS: A double-blinded randomized controlled study of technology and information was conducted at a modern university. A total of 108 individuals, 40-55 years who had experienced a traumatic amputation of one leg above the knee were divided into three groups: group A received whole body vibration (WBV) with their eyes opened, group B received (VFDWBV), and group C received conservative treatment only. The stability of the prosthetic leg, stability limit, and sway index (m-CTSIB) were assessed at the beginning and after 12 weeks. Sessions occurred three times each week. RESULTS: Significant statistical differences were seen in the stability of prosthetic legs, the limit of stability, and (m-CTSIB) between groups A and B, considering the treatment interaction (F = 24.8, p = 0.001). Additionally, the group receiving VFDWBV showed a more significant improvement in postural steadiness than those receiving WBV and the control group. CONCLUSION: Utilizing VFDWBV at a frequency of 30 HZ can significantly enhance the stability of posture in individuals with unilateral traumatic trans-femoral amputations. TRIAL REGISTRATION: The study was registered with the Clinical Trials.gov (NCT06284733).
