ABSTRACT

Objective To investigate the influence of chronic pain on the sleep quality in the patients with Parkinson′s disease (PD) .Methods 232 cases of PD in the neurology department of this hospital from March 2009 to March 2013 were selected and di‐vided into the pain PD group (PPD group ,106 cases) and the non‐pain PD group (NPPD group ,126 cases) according to whether accompanying chronic pain .Contemporaneous 140 individual of healthy physical examination were selected as the control group .The Pittsburgh Sleep Quality Index Scale (PSQI) and the fatigue scale (FS‐14) were used to judge whether sleep disorders existing . Then the differences in the sleep quality and fatigue condition were compared among three groups .The related factors of sleeping disorders were also analyzed .Results The scores of PSQI and FS‐4 had statistically significant differences among 3 groups (P<0 .05) ,in which the differences in the aspects of sleep latency ,subjective sleep quality ,sleep continuity ,habitual sleep efficiency and sleep disorders also were statistically significant (P<0 .05) .The influencing factors of sleeping disorders were the Hoehn‐Yahr stage (r = -0 .79 ,P<0 .05) ,dopamine dose (r = -0 .38 ,P=0 .04) ,presence of pain (r = -0 .57 ,P<0 .05) and severity of de‐pression (r = -0 .63 ,P<0 .05) .Conclusion The PD patients accompanying pain are more susceptible to develop sleep disorders , the sleep quality accompanying pain is worse than that without accompanying pain .Therefore the early intervention should be well conducted in clinic .
