Summary

Transcranial electrical stimulation (tCES) is a non-invasive and safe treatment, which uses a low direct current or alternating current to change the excitability of the cerebral cortex. The tCES has been applied in clinical trials related to rehabilitation research in recent years, and the safety and effectiveness have also been established. However, the existing tCES products effect on the whole brain networks and lack special waveforms. The investigators developed a wearable high-definition tCES (HD-tCES) with special waveforms. This novel stimulation system will result in more precise and focal stimulation of selected brain regions with special waveforms to display better neuromodulation performance. In this study, the investigators will preliminarily examine the effects and safety of the HD-tCES in patients with fibromyalgia. The investigators expect that the HD-tCES will relief pain, improve sleep quality, emotion, and general health of the patients.

Conditions

  • Fibromyalgia

Interventions

DEVICE

HD-tCES

The high definition transcranial electrical stimulation was applied using a 1\*4 ring electrode configuration. The electrode will be applied at the left M1 or contralateral to pain side. The anodal electrode was placed on the C3/C4, and the remaining 4 cathodal electrodes were placed in a radius of approximately 7.5 cm from anode (Cz, F3, T7, and P3 on the left hemisphere or Cz, F4, T8, and P4 on the right hemisphere). HD-tCES will be applied for 20 minutes at an intensity of 1.0 mA direct current stimulation and a specific-added waveform each time, 5 times a week, lasting for 2 weeks.

DEVICE

Sham HD-tCES

The high definition transcranial electrical stimulation was applied using a 1\*4 ring electrode configuration. The electrode will be applied at the left M1 or contralateral to pain side. The anodal electrode was placed on the C3/C4, and the remaining 4 cathodal electrodes were placed in a radius of approximately 7.5 cm from anode (Cz, F3, T7, and P3 on the left hemisphere or Cz, F4, T8, and P4 on the right hemisphere). Sham HD-tCES will consist of a 5-second ramp up to 1.0 mA direct current stimulation and a specific-added waveform followed immediately by a 5-second ramp down, no current in the middle 19 minutes 40 seconds, and a ramp-up and ramp-down period during the last 10 seconds.
