Background: Pain is a common and distressing symptom of Parkinson's disease (PD). The relation of pain, its predictors, and its impact on quality of life (QoL) in PD has not been studied in Indian PD patients.
Objective: To assess the predictors of pain and investigate its impact on QoL among Indian PD patients.
Methodology: We conducted a cross-sectional study on 100 PD patients. The cases were diagnosed according to the UK brain bank criteria. Unified PD Rating Scale (UPDRS) parts III, V, and VI were employed to assess the severity of the disease. King's Parkinson Disease Pain Scale (KPPS) and PD questionnaire-8 (PDQ-8) were used to evaluate pain and QoL, respectively.
Results: Prevalence of different pain types in patients with PD was 70%, mainly including musculoskeletal (53%), fluctuation-related (35%), and nocturnal pain (27%). Subjects with pain developed PD symptoms at a younger age and had a longer duration of the disease. A positive correlation was found between KPPS scores and UPDRS parts III and V, while a negative correlation was observed with UPDRS part VI. Pain in PD subjects had a significant impact on the QoL.
Conclusions: Most of the PD patients suffered some form of pain with significant correlations with motor disability and poor QoL. Predictors of pain severity among PD patients included a longer disease duration, younger age of disease onset, and a higher levodopa equivalent daily dose (LEDD).
