Exploration of the Effectiveness of Vibrational Intervention in Improving Insomnia Symptoms

Study Purpose The purpose of this clinical trial is to investigate whether low-intensity frontal vibration can improve sleep performance in individuals with chronic insomnia. Additionally, the study aims to explore its potential effects on memory enhancement.

The primary objectives of the study are to address the following questions:

* Does low-intensity frontal vibration improve sleep performance in patients with chronic insomnia? * Does low-intensity frontal vibration enhance memory performance in patients with chronic insomnia?

Researchers will compare the effects of low-intensity frontal vibration with a sham stimulation (in which participants hear only noise associated with the vibration process) to determine whether the active intervention can effectively improve symptoms of chronic insomnia.

Participant Involvement

Participants in the study will:

* Record daily sleep diaries via a mobile application for a total of 9 weeks * Receive daily intervention during a 4-week intervention phase as scheduled by the study * Complete weekly self-reported sleep questionnaires through the app * Undergo memory performance assessments at the beginning and end of the study
