Pain

Pain is common in adult life, and the extent to which pain interferes with daily activities rises with age. Little is known about the social factors associated with disabling pain. The objective was to determine the individual and neighbourhood social factors that predict pain that interferes with daily activities. ⋯ Whilst the onset of pain which disrupts daily life is influenced mainly by the characteristics of the pain and by the psychological factors, there are links with the social factors, particularly individual measures of perceived income adequacy. The onset of disabling pain is also influenced by the place where one lives. Policies to prevent disabling pain need to consider the contribution of neighbourhood deprivation and income inequalities to the extent of the problem.

When faced with the problem of pain one can attempt a solution aimed at relief (assimilation) or a solution aimed at acceptance (accommodation). Using this dual process model of adaptation to pain, this study compares acute and chronic pain patients on their approach to problem solving. Three hundred and sixty-four patients were recruited from clinical settings, 303 with chronic pain and 61 with acute pain, and completed a range of measures of both affect and pain-related behavior, including the Pain Solutions Questionnaire. ⋯ Only in the case of catastrophic thinking about pain was it found that the effects of assimilative coping were moderated by pain duration. For chronic pain patients, catastrophic thinking about pain was greater when assimilative coping was higher. These results are discussed within the context of a goal directed motivational model of adaptation to chronic pain.

Trying to control pain is a common human goal. But little is know about what happens when one loses control over pain. This paper reports an experiment with 74 healthy volunteers, half of whom were given control over a pain stimulus and subsequently lost control, and half of whom never had control over the pain. ⋯ These findings are discussed within the context of a dual process model of coping with uncontrollable adverse events [Brandtstädter J, Renner G. Tenacious goal pursuit and flexible goal adjustment: explication and age-related analysis of assimilative and accommodative strategies of coping. Psychol Aging 1990;5:58-67] and possible mechanisms for perseverance with ineffective solutions.

Chronic pain is often associated with reduced tactile acuity. A relationship exists between pain intensity, tactile acuity and cortical reorganisation. When pain resolves, tactile function improves and cortical organisation normalises. ⋯ Pain and TPD were lower after the discrimination phase [mean (95% CI) effect size for pain VAS = 27 mm (14-40 mm) and for TPD = 5.7 mm (2.9-8. ), p < 0.015 for both]. These gains were maintained at three-month follow-up. We conclude that tactile stimulation can decrease pain and increase tactile acuity when patients are required to discriminate between the type and location of tactile stimuli.
