“…Literature has well established that periods of augmented sensory input introduced with vibration markedly increase the excitability of neural circuits that control the motor output to the stimulated muscle [9][10][11]18,[22][23][24]. The increased MEP size found in the current study is consistent with such reports and in addition demonstrated expansion of the cortical representation area associated with the vibrated ECRL muscle.…”

“…Furthermore, we found that vibration-induced cortical modulation was sustained up to 5 min beyond the 15 min stimulation period. Arguably, we did not examine whether the changes could have been due to alterations in spinal excitability alone, although many others have provided convincing evidence that vibration applied as in the current study results in modulations at the cortical level [9][10]18,20]. For example, Kossev and colleagues showed that MEP facilitation induced by muscle vibration was evident after TMS but not transcranial electrical stimulation (TES) [9].…”

“…Kossev et al [9] reported an almost twofold increase in MEP amplitude in response to TMS applied immediately after briefduration, low-amplitude vibration of the extensor carpi radialis longus (ECRL) muscle at a frequency of 80 Hz. Others have confirmed that the excitability of corticospinal projections to the target muscle increases during vibration but also have indicated that the excitability to other nearby muscles is suppressed [10][11].…”

Abstract-This study explored the effect of vibration of the forearm extensors on motor cortical excitability and the influence of stimulus duration. Sixteen healthy volunteers between 23 and 42 years old participated in one or two studies. We applied 15 or 30 min of 100 Hz, 0.5 mm-amplitude vibration to the extensor carpi radialis longus (ECRL) muscle. Cortical excitability was measured as the magnitude of the motorevoked potentials (MEPs), and the size of the representation area associated with ECRL and flexor carpi ulnaris muscles was determined with the use of transcranial magnetic stimulation. A 33% increase in MEP size and enlarged area of cortical excitability was detected 5 min after 15 min of vibration in the ECRL only. No changes were associated with 30 min of vibration in either muscle. These findings indicate that the facilitatory effects of vibration in healthy subjects depend on stimulus duration and provide impetus for testing the extent to which shortduration vibration augments corticospinal excitability to improve muscle function in people with central motor disorders.

“…Some of these increases are considered due to increased excitability of spinal mechanisms (Claus et al 1988a;. In addition, recent studies comparing the effect of afferent input on responses to TMS have suggested that peripheral electrical and vibration stimulation influence the excitability of cortical mechanisms (Kossev et al 1999;Rosenkranz and Rothwell 2003). Although we cannot exclude spinal contributions to these results, our data on SICI, ICF, and MRCP are compatible with additional action on the MI.…”

Maruyama A. Whole-hand water flow stimulation increases motor cortical excitability: a study of transcranial magnetic stimulation and movement-related cortical potentials. J Neurophysiol 113: 822-833, 2015. First published November 5, 2014 doi:10.1152/jn.00161.2014.-Previous studies examining the influence of afferent stimulation on corticospinal excitability have demonstrated that the intensity of afferent stimulation and the nature of the afferents targeted (cutaneous/proprioceptive) determine the effects. In this study, we assessed the effects of whole-hand water immersion (WI) and water flow stimulation (WF) on corticospinal excitability and intracortical circuits by measuring motor evoked potential (MEP) recruitment curves and conditioned MEP amplitudes. We further investigated whether whole-hand WF modulated movement-related cortical activity. Ten healthy subjects participated in three experiments, comprising the immersion of participants' right hands with (whole-hand WF) or without (whole-hand WI) water flow, and no immersion (control). We evaluated MEP recruitment curves produced by a single transcranial magnetic stimulation (TMS) pulse at increasing stimulus intensities, short-interval intracortical inhibition (SICI), and intracortical facilitation (ICF) using the paired TMS technique before and after 15 min of intervention. Movement-related cortical potentials (MRCPs) were evaluated to examine primary motor cortex, supplementary motor area, and somatosensory cortex excitability upon movement before and after whole-hand WF. After wholehand WF, the slope of the MEP recruitment curve significantly increased, whereas SICI decreased and ICF increased in the contralateral motor cortex. The amplitude of the Bereitschaftspotential, negative slope, and motor potential of MRCPs significantly increased after whole-hand WF. We demonstrated that whole-hand WF increased corticospinal excitability, decreased SICI, and increased ICF, although whole-hand WI did not change corticospinal excitability and intracortical circuits. Whole-hand WF modulated movement-related cortical activity, increasing motor cortex activation for the planning and execution of voluntary movements.whole-hand water flow stimulation; primary motor cortex; corticospinal excitability; intracortical circuit; movement-related cortical potentials

Abstract:Background. Impaired motor control of the upper extremity after stroke may be related to lost sensory, motor, and integrative functions of the brain. Artificial activation of sensory afferents might improve control of movement by adding excitatory drive to sensorimotor control structures. The authors evaluated the effect of wrist tendon vibration (TV) on paretic upper-arm stability during point-to-point planar movements. Methods. TV (70 Hz) was applied to the forearm wrist musculature of 10 hemiparetic stroke patients as they made center-out planar arm movements. End-point stability, muscle activity, and grip pressure were compared as patients stabilized at the target NOT THE PUBLISHED VERSION; this is the author's final, peer-reviewed manuscript.

Results. Prior to vibration, hand position fluctuated as participants attempted to maintain the hand at the target after movement termination. TV improved arm stability, as evidenced by decreased magnitude of hand tangential velocity at the target. Improved stability was accompanied by a decrease in muscle activity throughout the arm as well as a mean decrease in grip pressure. Conclusions. These results suggest that vibratory stimulation of the distal wrist musculature enhances stability of the proximal arm and can be studied further as a mode for improving end-point stability during reaching in hemiparetic patients.
