Effect of Transcranial Direct Current Stimulation with Balance Training in a Middle-Aged Population: Randomized...

Area of Science:

• Neuroscience
• Gerontology
• Physical Therapy

Background:

• Balance impairment begins in middle age, increasing fall risk in older adults.
• Early intervention is crucial to address balance deficits and prevent falls.
• Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique.

Purpose of the Study:

• To evaluate the effects of tDCS combined with balance training (BT) on static and dynamic balance in middle-aged individuals.
• To assess the safety and satisfaction of participants undergoing the combined intervention.
• To determine if tDCS can enhance balance improvements beyond BT alone.

Main Methods:

• 28 middle-aged participants were randomized into active tDCS + BT or sham tDCS + BT groups.
• Intervention was administered thrice weekly for 6 weeks.
• Balance was assessed using sway rate (eyes open/closed) and functional reach test; safety and satisfaction were surveyed.

Main Results:

• The active tDCS group demonstrated significantly greater improvements in static and dynamic balance compared to the sham group.
• The combined intervention was found to be safe.
• 80% of participants reported satisfaction with the tDCS + BT program.

Conclusions:

• tDCS combined with BT is an effective strategy for improving balance in middle-aged adults.
• This approach may help mitigate age-related balance decline and reduce fall risk.
• The intervention is safe and well-tolerated, suggesting its potential for clinical application.
