“…This type of directed sensory rehabilitation is currently being explored, such as focal repetitive muscle vibration, which is a non-invasive post-stroke therapy to reduce muscle tone [ 42 , 43 ]. Another example is wearable focal stimulation devices, such as a vibrotactile glove (VTG), which provides vibratory input to the paretic limb of chronic stroke survivors and has been shown to promote neural plasticity and reduces spasticity [ 44 , 45 ]. Other studies have used robot-assisted somatosensory training and vibrotactile biofeedback devices [ 46 , 47 ].…”

The cortical motor system can be reorganized following a stroke, with increased recruitment of the contralesional hemisphere. However, it is unknown whether a similar hemispheric shift occurs in the somatosensory system to adapt to this motor change, and whether this is related to movement impairments. This proof-of-concept study assessed somatosensory evoked potentials (SEPs), P50 and N100, in hemiparetic stroke participants and age-matched controls using high-density electroencephalograph (EEG) recordings during tactile finger stimulation. The laterality index was calculated to determine the hemispheric dominance of the SEP and re-confirmed with source localization. The study found that latencies of P50 and N100 were significantly delayed in stroke brains when stimulating the paretic hand. The amplitude of P50 in the contralateral (to stimulated hand) hemisphere was negatively correlated with the Fügl–Meyer upper extremity motor score in stroke. Bilateral cortical responses were detected in stroke, while only contralateral cortical responses were shown in controls, resulting in a significant difference in the laterality index. These results suggested that somatosensory reorganization after stroke involves increased recruitment of ipsilateral cortical regions, especially for the N100 SEP component. This reorganization delays the latency of somatosensory processing after a stroke. This research provided new insights related to the somatosensory reorganization after stroke, which could enrich future hypothesis-driven therapeutic rehabilitation strategies from a sensory or sensory-motor perspective.

“…A recent report indicated that the vibrotactile component of the haptic feedback that occurs when playing a musical instrument leads to increased quality of hand perceptions [41]. Due to central mechanisms, vibrotactile stimulation on the ngertips results in not only activating cutaneous mechanoreceptors, but it also enhances the mechanical coupling between the contacted skin, tendons, and bones, which signi cantly improves the of touch-pressure threshold, as tested by Semmes-Weinstein mono lament [42] and the capacity of active force perception as measured when participants manipulate objects [43].…”

Background: Music-supported therapy (MST), a type of biofeedback therapy with multi-sensory information input, has been proposed as an effective approach to improving motor control in people with sensorimotor deficits. However, currently, MST training is restricted to being extensively applied for patients with various levels of defects in fine motor skills and cognitive functions. Therefore, the integration of passive haptic learning (PHL) with MST has been adopted as a motor training strategy intended to enhance “motor memory” learning through the use of vibration stimuli. The current study was designed to investigate differences in the sensorimotor performance of older adults’ hands under baseline, a single session of standard MST, and PHL-based MST conditions. Methods: Thirty healthy older adults were recruited and randomized to receive either the single session of 30-minutes of PHL-based MST or 30-minutes of standard MST at the beginning of the experiment. After a one-week washout period, they switched their treatment programs and then were assessed to study the training effects of both approaches through measuring precision pinch performance, hand function, and sensory status. Results: The results of the Pinch-Holding-Up Activity test revealed a statistically significant difference in the FRpeak parameter (F = 14.37, p < 0.001, η² = 0.507) under the PHL-based MST condition compared to the baseline and standard MST conditions. In addition, significant beneficial effects were found on the results of the barognosis (F = 19.126, p < 0.001, η² = 0. 577) and roughness differentiation subtests (F = 15.036, p < 0.001, η² = 0.518) in the Manual Tactile Test for the participants in the PHL-based MST group. In addition, the participants under both the standard MST and PHL-based MST conditions exhibited better performance in the three subtests of the Purdue Pegboard Test as compared to under the baseline condition (p < 0.016). Conclusions: The findings indicated that PHL-based MST potentially improves the precision pinch performance of hands in healthy older adults. In addition, the add-on effect of vibrotactile stimulation to the MST condition provides beneficial effects on the sensory functions of the upper extremities.
