title: The relationship of pain and health-related quality of life in Korean patients with Parkinson's disease.
abstract: BACKGROUND
  Parkinson's disease (PD) is a chronic progressive neurodegenerative disorder. Increasing attention has been focused on the pain and health-related quality of life (HrQOL) in patients with PD. Objective - To evaluate the relationship between pain and the HrQOL in patients with PD.
  
  
  METHODS
  Eighty-two patients with PD were included and classified into two groups according to the presence of pain. The Hoehn and Yahr scale, the Unified Parkinson's Disease Rating Scale (UPDRS), the Modified Somatic Perception Questionnaire (MSPQ), the Zung Depression Inventory--Self-rating Depression Scale (SDS), the Visual Analogue Scale and the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) were administered. The factors influencing the pain, HrQOL and parkinsonian manifestations were evaluated.
  
  
  RESULTS
  The PD with pain group had higher UPDRS part III scores, lower SF-36 scores, higher SDS scores and higher MSPQ scores than the PD without pain group. The presence of pain, high Hoehn and Yahr stage, advanced age and somatic perception were the factors that had a negative effect on the physical component of the HrQOL. Depression and somatic perception were the most important predictive factors for the mental component of the HrQOL. Depression and poor parkinsonian motor abilities were the leading factors contributing to pain.
  
  
  CONCLUSIONS
  Pain and depression were major detrimental factors affecting the physical and mental aspects of the HrQOL respectively. Therefore, the treatment of pain and depression can be important to improve the HrQOL.
