Hao MZ, et al. – This study aimed to test the hypothesis that cutaneous afferents could also influence the transmission of tremor signals, hence, inhibit tremor in patients with Parkinsonian tremor Parkinson’s disease (PD). The authors provided direct evidence that in the upper extremity of patients with PD, tremor could be inhibited to a large extent with evoked cutaneous reflexes via surface stimulation of the dorsal hand skin area innervated by the superficial radial nerve.
