“…One way to reduce sensory feedback is by means of limb immobilization. In this regard, immobilization of the upper limb in patients with focal hand dystonia resulted in changes of the cortical map toward a more normal topography (Lissek et al, 2009;Roll et al, 2012). Immobilization of specific body parts was also applied together with motor training (Candia et al, 2005;Zeuner et al, 2005).…”

Traditional definitions of focal dystonia point to its motor component, mainly affecting planning and execution of voluntary movements. However, focal dystonia is tightly linked also to sensory dysfunction. Accurate motor control requires an optimal processing of afferent inputs from different sensory systems, in particular visual and somatosensory (e.g., touch and proprioception). Several experimental studies indicate that sensory-motor integration - the process through which sensory information is used to plan, execute, and monitor movements - is impaired in focal dystonia. The neural degenerations associated with these alterations affect not only the basal ganglia-thalamic-frontal cortex loop, but also the parietal cortex and cerebellum. The present review outlines the experimental studies describing impaired sensory-motor integration in focal dystonia, establishes their relationship with changes in specific neural mechanisms, and provides new insight towards the implementation of novel intervention protocols. Based on the reviewed state-of-the-art evidence, the theoretical framework summarized in the present article will not only result in a better understanding of the pathophysiology of dystonia, but it will also lead to the development of new rehabilitation strategies.

“…Observations of cortical activity in individuals following limb immobilisation (Avanzino et al,26 2013; Bassolino, Bove, Jacono, Fadiga, & Pozzo, 2012;Roll et al, 2012) and transient deafferentation of the upper limb (Tinazzi et al, 1997) have found that plastic changes emerge rapidly within both motor and sensory cortices. Of interest was the finding that these neuroplastic changes did not occur in those patients who received supplementary proprioceptive stimulation through the duration of their immobilisation (Avanzino et al, 2013;Roll et al, 2012).…”

“…Of interest was the finding that these neuroplastic changes did not occur in those patients who received supplementary proprioceptive stimulation through the duration of their immobilisation (Avanzino et al, 2013;Roll et al, 2012). The importance of proprioceptive input on functional performance is illustrated by a study by Bassolino et al (2012) who demonstrated that a period of just 10 hours of immobilisation resulted in altered performance of a simple motor task.…”

“…reported an improvement in standing balance after vibration of the triceps tendon10 ) . Moreover, Roll et al reported that the stimulation of illusory movements prevented the cortical disruption normally caused by immobilization in healthy people and that the illusion of motion evoked by vibrating the tendon of a limb could likely prove to be an effective prophylactic treatment following surgery and cast immobilization with conservative therapy11 ) .…”

Brain Activity Associated with the Illusion of Motion Evoked by Different Vibration Stimulation Devices: An fNIRS Study

[Purpose] A number of different stimulation devices are used in basic and clinical research studies, and their frequencies of use vary. However, whether or not they are equally effective has not been investigated. The purpose of the present study was to investigate neural activity in the brain during the illusion of motion evoked by stimulating the tendons of the wrist extensor muscles using various vibration devices. [Subjects] Twelve right-handed university students with no history of nervous system disorder or orthopedic disease participated in the study. [Methods] The wrist extensor tendon was stimulated using 3 different devices: 1) a vibration stimulation device (SL-0105 LP; Asahi Seisakusho Co., Ltd., Saitama, Japan), frequency 80 Hz; 2) a handy massager (YCM-20; Yamazen Corporation, Osaka, Japan), frequency 70 Hz; and 3) a handy massager (Thrive MD-01; Thrive Co., Ltd., Osaka, Japan), frequency 91.7 Hz. Brain activity was recorded during stimulation by using functional near-infrared spectroscopy. [Results] Increased neural activity was observed in both the premotor cortices and the parietal region in both hemispheres in all 3 cases. The level and localization of neural activity was comparable for all 3 stimulation devices used. [Conclusion] This suggests that subjects experience the illusion of motion while the tendon is being stimulated using any vibration device.
