What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 30 participants in total. It began in 2025-05-06 with a primary completion date of 2027-05-01.

Brief 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.
