title: Long-term sick-leavers with fibromyalgia: Comparing their multidisciplinarily assessed characteristics with those of others with chronic pain conditions and depression.
abstract: OBJECTIVE
  The aim was to gain knowledge of fibromyalgia (FM) patients on long-term sick leave and with particular difficulties in resuming work, and to compare them with patients with myalgia, back or joint diagnoses, and depression.
  
  
  METHODS
  Patients were identified by and referred from social insurance offices and were multidisciplinarily examined by three board-certified specialists in psychiatry, orthopedic surgery and rehabilitation medicine. Ninety-two women were diagnosed with FM only. Three female comparison groups were chosen: depression, back/joint diagnoses, and myalgia.
  
  
  CONCLUSIONS
  Ceaseless pain was reported by 73% of FM patients, 54% of back/joint diagnoses patients, 43% of myalgia patients, and 35% of depression patients. The distribution of pain (>50%) in FM patients was to almost all regions of the body, and in depression patients to the lower dorsal neck, upper shoulders and lumbosacral back but not in the anterior body. Reduced sleep was more evident in FM patients. FM patients did not meet more criteria for personality disorder than patients with the other somatic pain conditions. The most common dimension of "personality traits" of somatic pain conditions was the "obsessive compulsive" but at a level clearly below that indicating a personality disorder. More FM patients experienced disabilities, the most common being in the mobility and domestic-life areas.
