Abstract
ObjectiveTo research the effects of progressive time phase selective light (PTPSL)therapy on shift work disorder patients.
Methods24 shift work disorder patients were randomly divided into PTPSL group and control group. Both groups received treatment for 12 days including 6 days during the night shift time and 6 days during the day shift time continuously.The clinical effects were evaluated by Karolinska Sleepiness Scale(KSS), Leeds sleep evaluation questionnaire (LSEQ) and core body temperature rhythm.
Results(1) During the night shift time, PTPSL group patients were better in score LSEQ and KSS(discerned for 39.80±2.89, 6.59±0.48) than control group’s(discerned for 36.86±3.88, 6.98±2.03); temperature curve peak phase in PTPSL group moved backward greater than that of control group((8.35±0.82)h vs (7.45±1.05)h); and the difference was statistical significance(P<0.05). During the day shift time, PTPSL group patients were better in score LSEQ and KSS(discerned for 45.57±2.77, 6.33±0.48) than control group’s(discerned for 40.35±4.19, 6.82±1.03), temperature curve peak phase in PTPSL group moved forward greater than that of control group((7.37±0.94)h vs (6.31±1.37)h), and the difference was statistical significance(P<0.05).
ConclusionPTPSL can adjust shift sleep disorder patients’ mussily sleep rhythm system in order, and make the inner rhythm system and external schedules tend to be consistent, and provides a new treatment choice for shift sleep disorders.
