Pain reporting in older adults: the influence of cognitive impairment - results from the Cambridge City >75 Cohort study.
Evidence suggests that while disabling back pain (BP), and rheumatic diseases associated with pain, continues to increase with age, the prevalence of non-disabling BP reaches a plateau, or even decreases, in the oldest old. This study aimed to determine whether this age-related pattern of non-disabling BP is a function of increasing cognitive impairment. ⋯ Prevalence of non-disabling back pain decreases in the oldest old.Some have proposed that this may be a function of cognitive impairment in older age, and an increasing inability to adequately report pain.Our findings do not support this hypothesis.

Compelling evidence points at both impaired proprioception and disturbed force control in patients with chronic complex regional pain syndrome (CRPS). Because force modulation at least partly relies on proprioception, we evaluated if impaired sense of force production contributes to disturbances of force control in patients with CRPS. ⋯ CRPS patients, in particular those with abnormal postures, showed impaired voluntary force control and an impaired sense of force production. This suggests that therapeutic strategies aimed at restoration of proprioceptive impairments, possibly using online visual feedback, may promote the recovery of motor function in CRPS.

Low back pain (LBP), obesity, and depression are highly prevalent health conditions. We assessed the relative impact of body weight and depression on different types of LBP in a representative population sample. ⋯ BMI and depression are modifiable risk indicators for chronic disabling LBP.

The difficulty in identifying the onset of low back pain (LBP) limits the capacity to determine the incidence of LBP at the population level and, further, to identify risk factors. In the literature, incidence cohorts have been built with patients initially considered LBP-free for 6-12 months prior to their selection. This 'clearance period' might not be sufficient to exclude recurrent patients having experienced previous LBP episodes and might result in a misclassification bias. ⋯ Screening the medical history of LBP patients can provide more accurate incidence estimates by limiting the over-ascertainment of first-time LBP patients. A 4- to 7-year clearance period should be considered.

Relationship between sleep, pain, and disability in patients with spinal pathology.
To characterize sleep and its relationship with disability and pain in patients with spine pathology. ⋯ Despite its being intuitive that sleep disorders will be present in patients with spinal disorders, it was surprising that sleep quality was an independent predictor of disability along with pain. Furthermore, sleep quality is more closely correlated to disability than leg pain, which is the current focus of medical interventions.
