Abstract

The objective of the present study was to determine the effectiveness of a three-week Whole-Body Vibration (WBV) training on the vascular blood flow of the lower limbs in children with myelomeningocele. The secondary goal was to evaluate the effect of WBV on the ROM of lower limb joints in this population. A total of 30 children with MMC (7–16 years old) were enrolled in the study. Children were randomly allocated to two groups of equal numbers, using an envelope code. The experimental group underwent a 3-week WBV training, while the control group received a 3-week conventional physiotherapy (PT) program. The examination consisted of two parts: (1) Doppler USG examination of the lower limb vascular blood flow; (2) evaluation of ROM. The results obtained revealed three main findings. First, WBV training effectively improved blood flow by increasing flow velocities in all tested arteries, while the impact of the PT program was limited to a single parameter. Second, WBV training effectively improved vascular resistance in arteries of the lower legs, while the PT program did not achieve any significant differences. Third, both types of treatment intervention significantly improved ROM in all joints of the lower limbs in MMC participants.

Highlights

Spina bifida (SB) is a congenital spinal column malformation, caused by the incomplete closure of the neural tube during embryonic development [1]
Our findings showed that Whole-Body Vibration (WBV)-PT significantly improved both vascular properties in individuals with MMC and the range of movement (ROM) of lower limb joints, the effectiveness of WBV alone has not been determined [7]
The analysis of variance showed homogeneity between experimental and control groups. The participants in both groups did not differ in terms of the subject characteristics

Summary

Introduction

Spina bifida (SB) is a congenital spinal column malformation, caused by the incomplete closure of the neural tube during embryonic development [1]. Depending on the degree of severity of the spinal cord malformation, there are three types of malformations: (1) Spina bifida occulta (SBO); (2) meningocele (MC); and (3) myelomeningocele (MMC) [2]. MMC is the most severe form of spinal cord malformation. This occurs when the spinal cord is pushed through the opening in the spine resulting in partial or complete paralysis of the parts of the body below the spinal opening. If part of the spinal cord below the MMC is intact and has innervation, the result is a spastic type of motor paralysis
