Investigation of actigraphy in diagnosis for non-organic insomnia

Objective To evaluate the effects of actigraphy in diagnosis for non-organic insomnia.Methods Actigraphy was employed to evaluate the sleep effects for 34 cases of non-organic insomnia and 20 controlling cases,while Pittsburgh Sleep Quality Index(PSQI) was used to assess sleep qualities for these subjects during the latest month.Results In contrast to the controlling group,the non-organic insomnia group demonstrated significant prolongation of actual sleep time(AST),sleep latency(AS),mean wake bout time(MWBT)(P0.01)and decrease of sleep efficiency(SE) and mean length immobility(MLI)(P0.01),whilst mean activity score(MAS)and fragmentation index(FI) were obviously improved(P0.05).All PSQI for the non-organic insomnia group were more than 7,reaching 16.88±4.56;but for the controlling group,the PSQI were not up to 7,only with the scores of(4.53)±1.69,which showed significant difference(P0.01).Conclusion Actigraphy is an effective accessory way for the diagnosis of non-organic insomnia.
