Transcranial Direct Current Stimulation Associated With Functional Exercise Program for Treating Fibromyalgia: A...

Area of Science:

• Neurology
• Rehabilitation Medicine
• Pain Management

Background:

• Fibromyalgia (FM) is a chronic condition characterized by widespread pain and functional impairment.
• Current treatments often involve a multimodal approach, including exercise and pharmacotherapy.
• The potential of non-invasive brain stimulation techniques like tDCS to augment exercise benefits in FM requires further investigation.

Purpose of the Study:

• To evaluate the efficacy of transcranial direct current stimulation (tDCS) when combined with functional exercise for managing fibromyalgia symptoms.
• To assess the impact of tDCS plus functional exercise on pain intensity, functional performance, psychological distress, and quality of life in FM patients.

Main Methods:

• A randomized controlled trial was conducted with 31 women diagnosed with fibromyalgia.
• Participants were assigned to either anodal tDCS or sham-tDCS group, both receiving functional exercise training over 8 weeks.
• Interventions included daily tDCS (2mA, 20min) for 5 days, followed by thrice-weekly functional exercises.

Main Results:

• Both the tDCS and sham groups demonstrated significant improvements in pain, functional performance, psychological symptoms, and quality of life.
• No statistically significant differences were observed between the tDCS and sham groups across all measured outcomes.
• The addition of tDCS did not provide additional benefits beyond those of functional exercise alone.

Conclusions:

• Transcranial direct current stimulation (tDCS) combined with functional exercise does not appear to offer superior benefits compared to functional exercise alone for fibromyalgia patients.
• Further research may be needed to explore optimal parameters or patient subgroups for tDCS efficacy in FM.
• Functional exercise remains a key component in managing fibromyalgia symptoms.
