“…Furthermore, Kojima et al (34) showed that TS can modulate corticospinal excitability and that its effects also depend on stimulation patterns. Finally, Tanaka et al (35) reported the findings similar to our present results: TS applied to the first and second digits did not have an effect on the MEP amplitude in the FDI and ADM. It seems reasonable to suggest that TMS timing with respect to TS onset and its latency are important for MEP change to occur.…”

Tactile Imagery (TI) remains a fairly understudied phenomenon despite an increased attention to this topic in recent years. Here we investigated the effects of TI on corticospinal excitability by measuring motor evoked potentials (MEPs) induced by single-pulse transcranial magnetic stimulation (TMS). The effects of TI were compared with those of tactile stimulation (TS) and kinesthetic motor imagery (kMI). Twenty two participants were asked to perform three tasks in random order: imagine finger tapping (kMI); perceive vibration sensations on the middle finger (TS); and mentally reproduce these tactile sensations (TI). We found no statistically significant difference in MEP amplitudes between baseline and TS condition, whereas both TI and kMI facilitated corticospinal excitability. MEP amplitudes during TI were significantly lower compared to MEP amplitudes during kMI condition. This finding confirms the differential effects of TI and kMI on corticospinal excitability, which has practical implications for the development of imagery-based brain-computer interfaces (BCIs), particularly the ones intended to improve neurorehabilitation by evoking plastic changes in sensorimotor circuitry.

“…52 Another study has found that AOT and MI simultaneously trigger somatosensory stimulation, which can induce stronger excitability of the motor cortex than either AOT or MI alone. 53 Parkkonen et al pointed out the importance of sensorimotor integration for patients who had a stroke with good motor recovery. 54 However, many post-stroke upper limb rehabilitation methods still focus on motor function injury and recovery.…”

IntroductionThis study protocol aims to explore the effectiveness and neural mechanism of the integration of action observation therapy (AOT) and sensory observation therapy (SOT) for post-stroke patients on upper limb sensorimotor function.Methods and analysisThis is a single-centre, single-blind, randomised controlled trial. A total of 69 patients with upper extremity hemiparesis after stroke will be recruited and randomly divided into an AOT group, a combined action observation and somatosensory stimulation therapy (AOT+SST) group, and a combined AOT and SOT (AOT+SOT) group in a 1:1:1 ratio. Each group will receive 30 min of daily treatment, five times weekly for 4 weeks. The primary clinical outcome will be the Fugl-Meyer Assessment for Upper Extremity. Secondary clinical outcomes will include the Box and Blocks Test, modified Barthel Index and sensory assessment. All clinical assessments and resting-state functional MRI and diffusion tensor imaging data will be obtained at pre-intervention (T1), post-intervention (T2) and 8 weeks of follow-up (T3).Ethics and disseminationThe trial was approved by the Ethics Committee of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Chinese Traditional Medicine (Grant No. 2020-178). The results will be submitted to a peer-review journal or at a conference.Trial registration numberChiCTR2000040568

“…Mikula et al reported that the tactile stimulation of the left index finger before the right-hand movement could better determine the spatial position of the left finger and that the movement of the right hand towards the left index finger was dealt with more accurately when the left finger was invisible (22). In addition, it was reported that the tactile stimulation could increase the primary motor cortex excitability during mental imagery (18). However, the duration and frequency of tactile stimulation seem to be important parameters on the efficacy of tactile stimulation.…”

Effect of Tactile Stimulation on Hand Mental Rotation Among Young Healthy Adults: A Randomized Controlled Trial

et al. 2020

View full text Add to dashboard Cite

Background: In the hand mental rotation task, images and line drawings of hand at different angles are shown to the subjects, and they are asked to choose which hand (left or right) it is. Tactile stimulation is an appropriate technique to improve sensory and motor functions. Objectives: The present study aimed to investigate the impact of tactile stimulation on the hand mental rotation task. Methods: To meet the study objectives, 91 right-handed university students were selected to participate in this study. They were randomly divided into control (n = 41) and tactile stimulation (n = 50) groups. Participants were asked to perform a hand mental rotation task before and after tactile stimulation. The task required participants to judge the laterality (left or right) of hands as quickly and accurately as possible. The tactile stimulation was applied to the right index fingertip (16 Hz for 30 min). Results: In the tactile stimulation group, all angles for both right-and left-hand participants were analyzed, demonstrating significant decreases in the reaction time (P = 0.004) after tactile stimulation (mean: 1,908.24 ± 375.42 to 1,721.21 ± 428.99 milliseconds). In this group, the response accuracy rate increased considerably (P < 0.001) after tactile stimulation (mean: 78.43% ± 16.58 to 84.38% ± 18.15). In the control group, no significant differences were found between the measured parameters before and after sham stimulation. Conclusions:The current study demonstrated that tactile stimulation could improve hand mental rotation in healthy young adults, probably due to increased brain excitability and plasticity.
