pubmed-article:19362880 | pubmed:abstractText | Noxious digital nerve stimulation leads to transient suppression of the electromyographic activity in isometrically contracted hand muscles, known as the "cutaneous silent period" (CSP). To date, neurotransmitters potentially involved in mediating this electromyographic (EMG) suppression remain unknown. Anecdotal observation lead to the hypothesis that antihistaminic medication may counteract nociceptive EMG suppression, as CSPs in one male subject who was accustomed to CSP recordings were temporarily lost following ingestion of an antihistaminic drug for acute rhinitis. A second otherwise healthy male subject, who was on long-term cetirizine for allergic rhinitis, presented without clearly defined CSPs when volunteering for normal values. | lld:pubmed |
