Key Points

To evaluate sleep quality and excessive daytime sleepiness in complex regional pain syndrome (CRPS) and explore their associations with pain characteristics, functional impairment, depressive symptoms, and pain coping strategies.
Conducted a pilot cross-sectional observational study using a convenience sample of 21 adults with CRPS Type I (n=17) or Type II (n=4) at a single tertiary rehabilitation center.
Assessed sleep using the Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS), pain via NRS, SF-MPQ, and PDQ, limb disability via DASH (n=10) or LEFS (n=11), and psychological factors and central sensitization via BDI-II, CSQ, and CSI.
Poor sleep quality (PSQI > 5) was present in 81.0% (17/21) of participants (mean PSQI: 10.1 ± 4.1), and ESS-defined excessive daytime sleepiness occurred in 47.6% (10/21) of participants (mean ESS: 9.6 ± 5.8).
Global PSQI scores correlated significantly with NRS pain intensity (ρ = 0.445, p = 0.0431), SF-MPQ sensory pain (ρ = 0.468, p = 0.0325), SF-MPQ affective pain (ρ = 0.461, p = 0.0354), and SF-MPQ total score (ρ = 0.504, p = 0.0199).

Implication

Observational study reveals high rates of poor sleep quality and daytime sleepiness in complex regional pain syndrome patients, indicating a strong link to sensory and affective pain severity.
