Sensory electrical stimulation for suppression of postural tremor in patients with essential tremor

Abstract: Abstract. Essential tremor is an involuntary trembling of body limbs in people without tremor-related disease. In previous study, suppression of tremor by sensory electrical stimulation was confirmed on the index finger. This study investigates the effect of sensory stimulation on multiple segments and joints of the upper limb. It denotes the observation regarding the effect's continuity after halting the stimulation. 18 patients with essential tremor (8 men and 10 women) participated in this study. The task, … Show more

“…It is well-established that thalamic deep brain stimulation (Kalia et al, 2013) as well as stimulation of the dorsal column of the spinal cord (Fuentes et al, 2009) can desynchronize the neural activity causing several PD symptoms including tremor. Continuous surface stimulation of muscles at levels below motor threshold is also effective for tremor suppression, and may even last for several minutes after stimulation has been stopped (Heo et al, 2015). It can be hypothesized that our randomly timed stimulation may have evoked similar tremor suppression pathways as in Heo et al (2015), although it is likely that such pathways are better stimulated with continuous rather than random stimulation.…”

It can be hypothesized that our randomly timed stimulation may have evoked similar tremor suppression pathways as in Heo et al (2015), although it is likely that such pathways are better stimulated with continuous rather than random stimulation. The effectiveness of appropriately-timed stimulation in our study demonstrates that Ia inhibitory pathways can be recruited for the purpose of tremor suppression.…”

“…Non-invasive wearable devices that stimulate or exert forces on the affected limb are an appealing alternative 23,24 . Examples of these devices span robotic exoskeletons 25,26 , functional electrical stimulation systems 27 , or devices that aim at recruiting afferent pathways [28][29][30] . Although many of them showed clear improvements during standard clinical tasks in convenience samples of patients, none of them -to the best of our knowledgehas gone beyond laboratory trials.…”
