چکیده انگلیسی


• Tonic muscle pain either increases or decreases muscle sympathetic nerve activity.
• These response patterns are consistent across subjects and over time.
• Do differences in anxiety or attitudes to pain account for the different patterns?
• STAI, PVAQ, PASS and PCS questionnaires were administered.
• None of the psychological assessments could explain the different response patterns.

We have recently shown that intramuscular infusion of hypertonic saline, causing pain lasting ~ 60 min, increases muscle sympathetic nerve activity (MSNA) in one group of subjects, yet decreases it in another. Across subjects these divergent sympathetic responses to long-lasting muscle pain are consistent over time and cannot be foreseen on the basis of baseline MSNA, blood pressure, heart rate or sex. We predicted that differences in anxiety or attitudes to pain may account for these differences. Psychometric measures were assessed prior to the induction of pain using the State and Trait Anxiety Inventory (STAI), Pain Vigilance and Awareness Questionnaire (PVAQ), Pain Anxiety Symptoms Scale (PASS) and Pain Catastrophising Scale (PCS); PCS was also administered after the experiment. MSNA was recorded from the common peroneal nerve, before and during a 45-minute intramuscular infusion of hypertonic saline solution into the tibialis anterior muscle of 66 awake human subjects. Forty-one subjects showed an increase in mean burst amplitude of MSNA (172.8 ± 10.6%) while 25 showed a decrease (69.9 ± 3.8%). None of the measured psychological parameters showed significant differences between the increasing and the decreasing groups. We conclude that inter-individual anxiety or pain attitudes do not determine whether MSNA increases or decreases during long-lasting experimental muscle pain in healthy human subjects.
