Study Details

Brief summary:

Chronic pain is one of the main factors influencing workers' retention at work. Considering that the prevalence of suffering from chronic pain increases with age, older workers are most likely to be absent from work because of their pain.

Transcranial direct current stimulation (tDCS) is a treatment option to reduce chronic pain.

This study aims to document the effect of tDCS on pain and work retention in older workers and to compare the traditional tDCS protocol (5 sessions) with an enhanced protocol (11 sessions).
