The effects of central post-stroke pain on quality of life and depression in patients with stroke

[Purpose] The aim of this study was to assess the effects of central poststroke pain on quality of life, functionality, and depression in stroke. [Subjects and Methods] Twenty-four patients with stroke having central poststroke pain (a mean age of 60.6±8.5 years; 14 males, 10 females; Group I) and 24 similar age-and gender-matched patients with stroke without central poststroke pain (Group II) were enrolled. Characteristics of pain were recorded in patients with stroke having central poststroke pain. The Visual Analogue Scale and Leeds Assessment of Neuropathic Symptoms and Signs pain scale were used to evaluate pain. The Functional Independence Measure was used to assess functionality, the 36-Item Short-Form Health Survey was used to assess quality of life (QoL), and the Beck Depression Inventory was used to assess depression. [Results] There were no significant differences in Functional Independence Measure and Beck Depression Inventory. Some of the 36-Item Short-Form Health Survey domains (physical role limitations, pain, and physical scores) in Group II were significantly higher than those in Group I. Additionally, we found that a unit increase in Leeds Assessment of Neuropathic Symptoms and Signs score led to 0.679 decrease in physical score and 0.387 decrease in mental score. [Conclusion] The physical component of the 36-Item Short-Form Health Survey is negatively affected in patient with central poststroke pain, but the mood and mental components of the scale unaffected.
