Whole-Body Vibration Approaches in Neurological Disorders

Bipedalism in humans is associated with an upright spine, however, this condition is not found in other animals with that skill. This may have favored the ability to harness the influence of the gravitational forces on the body. Furthermore, it is suggested that human feet have evolved to facilitate bipedal locomotion, losing an opposable digit that grasped branches in favor of a longitudinal arch that stiffens the foot and aids bipedal gait. Gait is a repetition of sequences of body segments to move the body forward while maintaining balance. The bipedal gait favors the contact of the feet of the individual with the floor. As a result, the mechanical vibration (MV) generated during walking, running or other activity with the feet are, normally, are added to the body. In these various situations, the forces would induce the production of MV with consequent transmission to the whole body of the individual and there is the generation of whole-body vibration (WBV) exercise naturally. However, when a person has a disability, this normal addition of the MV to body does not occur. This also happens with the sedentary or bedridden individual due to illness. In this case, there are the MV yielded in vibrating platforms. The exposure of the individual to the WBV leads to physiological responses at musculoskeletal, neurological, endocrinological, and vascular levels. Considering the state of the art of this theme and the previously cited scientific information, it is plausible to assume that WBV could be a useful tool to be used on the management of individuals with neurological conditions, such as in Parkinson’s disease, stroke, cerebral palsy, multiple sclerosis, spinal cord injuries, spinocerebellar ataxia and Duchenne muscular dystrophy, and neuropathy (diabetes- and chemotherapy-related), among others. Indeed, improvements due to the WBV have been described regarding motor, and other impairments, in patients with neurological conditions, and these approaches will be presented in this chapter
