The visual analogue scale (VAS) and ordered categorical scales, i.e. numeric rating scales (NRS), are commonly used in the assessment of pain. However, these scales are bounded by fixed endpoints and thus the range of measurement is limited. The disparity in repeated assessments of perceived pain intensity with the VAS, NRS, and electrical stimulation applied as a matching stimulus was studied ...

OBJECTIVE This study compared changes in bodily pain, health-related quality of life (HRQoL), and psychological symptoms during an 8-week mindfulness-based stress reduction (MBSR) program among groups of participants with different chronic pain conditions. METHODS From 1997-2003, a longitudinal investigation of chronic pain patients (n=133) was nested within a larger prospective cohort study ...

Meyers, Millis, and Volkert [Meyers, J. E., Millis, S. R., & Volkert, K. (2002). A validity index for the MMPI-2. Archives of Clinical Neuropsychology, 17, 157-169] developed a method to detect malingering in chronic pain patients using seven scales from the Minnesota Multiphasic Inventory-2 (MMPI-2). This method may be impractical because two of the scales (Obvious minus Subtle and Dissimulati...

How chronic pain affects brain functions remains unclear. As a potential indicator, brain complexity estimated by entropy-based methods may be helpful for revealing the underlying neurophysiological mechanism of chronic pain. In this study, complexity features with multiple time scales and spectral features were extracted from resting-state magnetoencephalographic signals of 156 female particip...

BACKGROUND Neck dissection surgery is often followed by chronic head and neck pain. To date optimal treatment of this type of pain is lacking. Botulinum toxin type A (BTX-A) has been shown to be effective in the treatment of myofascial pain syndrome and headache. In a pilot study, we wanted to test the effectiveness of BTX-A for the treatment of chronic neck pain after neck dissection. METHOD...
