چکیده

P ain is a very frequent condition in worldwide population. In low-and middle-income countries the prevalence of any type of chronic pain is 33% in adult population, 56% in elderly population, and 35% in workers 1. Considering chronic widespread pain, we have observed estimates around 10% to 15%, with higher prevalence in women and in those with more than 40 years 2. Pain is one of the main causes of absence at work and it affects productivity and burden of disease. In a recent report by the Global Burden of Disease Study 2013, among 188 countries, leading causes of years lived with disability (YLD) were low back pain and major depressive disorder among the top ten causes of YLDs in every country.

Working memory has been evaluated by different instruments, revealing heterogeneity through studies. Executive dys-function is an umbrella, with many sides and with very heterogeneous evaluation and results 5,6. Other factors are correlated to possible cognitive impairment in pain sufferers, one of them is physical inactivity. We know that physical exercise is good for a better cognitive maintenance 7 ; and a systematic review with 1,159 older adults has showed that subjects with chronic pain have had a significantly lower level of physical activity compared with 576 elders without chronic pain 8. We can observe through studies that a huge amount of different methods has been used to evaluate cognitive performance, sometimes studies have utilized validated instruments, some of them have used self-report measures, and others neuropsychological instruments. Most of these instruments have not been validated for pain patients 9. Thickness …
