Examining the Effects of Theta Burst TMS on Brain Connectivity and Balance Ability in Older Adults With Balance Problems

Treating Balance Impairment of the Elderly With TMS-induced Brain Connectivity

Enrollment

30 participants

Start Date

Study Type

INTERVENTIONAL

Conditions

Aging

Summary

The goal of this study is to learn if manipulating the brain using magnets works to treat balance impairment, a major cause of falls, in older adults with balance problems. The technique to manipulate the brain using magnets is known as transcranial magnetic stimulation or TMS. The main questions this study aims to answer are: * How does TMS change communication between brain areas? * Does TMS improve balance ability in older adults with balance problems? Researchers will compare the TMS group to a placebo group to see if manipulating the brain using magnets works to treat balance impairment. Participants will: * Receive TMS or placebo stimulation for 4 weeks. * Visit the laboratory for checkups and tests 3 times.

Interventions

DEVICETranscranial Magnetic Stimulation

TMS (in the form of theta burst stimulations) will be delivered over Supplementary Motor Area while the subject is seated in the Treatment group. TMS is capable to induce neuroplastic facilitatory changes in the brain that last beyond the duration of stimulation. TMS will be delivered once daily, 5 days per week, for 4 weeks.

DEVICETranscranial Magnetic Stimulation Sham

Sham TMS will be delivered in the sham group using a sham coil once daily, 5 days per week, for 4 weeks.
