Non-invasive Brain Stimulation for Gait Instability
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new method to improve walking stability in older adults at risk of falling. It uses transcranial direct current stimulation (tDCS), a non-invasive technique that gently stimulates the brain, to determine if it can enhance brain function related to walking and attention. Participants will receive either tDCS or a sham treatment (a fake version used as a control) to compare effects. The trial seeks individuals aged 65 and above who can walk for at least one minute but have unstable walking patterns. As an unphased trial, it offers participants the chance to contribute to innovative research that could enhance mobility and quality of life for older adults.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you cannot participate if you have recently used sedating medications or changed your medication in the past month.
What prior data suggests that this non-invasive brain stimulation is safe for older adults?
Research has shown that transcranial direct current stimulation (tDCS) is usually easy for people to handle. One study found tDCS to be safe when combined with treadmill walking exercises, with no major side effects reported. Another study combined tDCS with physical therapy for older adults and found it safe and practical, even for those who were very frail. These findings suggest that tDCS might be a safe option for addressing walking problems. While these results are promising, individual experiences may vary.12345
Why are researchers excited about this trial?
Researchers are excited about transcranial direct current stimulation (tDCS) for gait instability because it offers a non-invasive way to potentially improve mobility. Unlike other treatments that may rely on medication or physical therapy, tDCS involves delivering a mild electrical current to the brain to enhance neural activity and improve walking stability. This technique is promising because it can be administered without surgery or drugs, reducing the risk of side effects and making it a more accessible option for patients. Additionally, tDCS sessions are relatively quick and can show results in a shorter period compared to traditional therapies.
What evidence suggests that transcranial direct current stimulation (tDCS) is effective for gait instability?
This trial will evaluate the effects of transcranial direct current stimulation (tDCS) on gait instability. Research has shown that tDCS can improve walking and balance. Studies suggest that tDCS is particularly beneficial for people with Parkinson's disease, enhancing their ability to walk and maintain balance. One study found that tDCS, when combined with treadmill exercises, increased walking speed. Although the quality of the evidence is considered low, these findings indicate that tDCS could be a promising therapy for improving walking and balance skills. Participants in this trial will receive either tDCS intervention or a combination of sham and then tDCS to assess its effectiveness.56789

Are You a Good Fit for This Trial?
This trial is for adults aged 65 or older who can walk on their own and have a high variability in their walking pattern, which may increase the risk of falls. They must speak English and be able to walk continuously for at least one minute. People with severe pain affecting walking, recent serious illnesses, significant cognitive impairment, certain neurological disorders, uncontrolled heart conditions, active cancer treatment, psychiatric issues or those taking sedating medications are not eligible.Inclusion Criteria
