Whole-Body Vibration Without Visual Feedback on Postural Steadiness in Unilateral Trans-Femoral Traumatic Amputees: A Randomized Controlled Trial.

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).
