A randomized trial of CES integrated with music on sleep improvement.

BACKGROUND

Insomnia population have a number of negative daytime consequences and experience fatigue and irritability. CES or Music has been reported as a self-help tool to improve insomnia with few data support. Thus, a systematic randomized controlled trial study is needed to establish the efficacy of CES integrated with music for insomnia as an alternative strategy.

METHODS

Study is based on a quasi-random process. All participants have been divided into three such as control group with treatment-as-usual (TAU) alone, CES plus double beat added to TAU, CES plus Pink noise added to TAU. Sleep onset latency (SoL), Total sleep time (TST), Proportion of deep sleep and Sleep quality have been analyzed.

RESULTS

A significant effect of CES plus music on improvement of SL and quality of life (QoL) has been found, but no effect on TST and proportion of deep sleep. Age group from 20 to 29 years shows better adaptability and recoverability to the intervention.

CONCLUSIONS

Our study shows a significant effect of CES plus music on perceived sleep improvement and quality of life with safety. Future studies should explore that whether CES plus music could be applied as an adjuvant or preventive strategy to standard treatment for persons with insomnia or subtypes.
