The aim of this study was to evaluate gait and balance outcomes in patients with essential tremor (ET)-only and tremor-dominant Parkinson's disease with or without ET (TDPD ± ET) who have undergone MRgFUS thalamotomy for treatment of their tremors, using validated, multidimensional measures.</p><p><strong>Methods: </strong>This retrospective review included all consecutive patients who underwent MRgFUS thalamotomy between June 14, 2021, and February 1, 2023. Patients who did not have a preprocedure or postprocedure gait and balance evaluation, and those lost to follow-up, were excluded. Primary outcomes were changes in the preprocedural and postprocedural Tinetti gait and balance scores and timed up and go time at the 3-month visit. Additional outcomes included changes in ambulation time, steps taken to walk 30 feet, and clinical improvement.</p><p><strong>Results: </strong>Of 92 total patients (72 ET-only, 20 TDPD ± ET), the ET-only cohort had a median follow-up of 94 days (IQR 91-113), and the TDPD ± ET cohort had a follow-up of 99.5 days (IQR 92.25-119.00). In ET-only patients, significant improvements were observed in median Tinetti balance (pre 15 [IQR 12-16] vs post 15 [IQR 13-16], P = .031) and median 30-ft ambulation time (8.11 seconds [IQR 6.74-10.77] vs 8.06 seconds [IQR 6.21-10.23], P = .009), with no change in median Tinetti gait, Tinetti total scores, timed up and go time, or steps to ambulate 30-ft. In patients with TDPD ± ET, only the median Tinetti gait improved (9.00 [IQR 6.00-11.00] vs 9.50 [IQR 7.75-12.00], P = .004).</p><p><strong>Conclusion: </strong>MRgFUS thalamotomy is associated with a low risk of gait/balance disturbances and may also improve these functions in patients with ET and TDPD ± ET.
