To examine the association between pain and functional capacity levels. ⋯ There is an inverse association of tender points count with the chair stand and distance walked in the 6-minute walk tests, and a positive association of algometer score with the chair stand, distance walked in the 6-minute walk and back scratch tests, yet, weight status seems to play a role in these associations.

To address how health professionals may inadvertently contribute to the stigmatization of patients with chronic pain. ⋯ Greater awareness by health professionals of their own potential, often inadvertent, contribution to the stigmatization of their patients with chronic pain may serve as a basis for an expanded model of clinical engagement.

Case Reports
Self-mutilation in patients after nerve injury may not be due to deafferentation pain: a case report.
Animals with transected nerves may develop self-mutilating behavior (autotomy) directed at the denervated body part. Autotomy is often thought to be a response to deafferentation pain produced by pathological changes in the dorsal horn, and self-mutilation after dorsal rhizotomy has consequently been used as an outcome measure for the investigation of chronic pain in animal models. A less recognized hypothesis suggests that autotomy is simply an animal's efforts to remove the useless part. We report a case of self-mutilation of the thumb and fingers in a patient with loss of all sensory modalities in the arm after brachial plexus avulsion. ⋯ Asking the patient about the reasons for his self-mutilation provides insights into the cause of autotomy which cannot be established from animal studies. We suggest that autotomy may not be a result of chronic pain, and discuss the human experience and alternative underlying pathological processes.
