What the trial was testing
The trial enrolled 27 patients with parkinson's disease. The study was sponsored by InSightec and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
Researchers followed patients through treatment and into recovery, tracking the outcomes that mattered most for the disease being studied.
What the results showed
Focused ultrasound reduced medication-resistant Parkinson's tremors by 62%.
JAMA neurology · 2017 · NCT01772693
These findings — that hand tremors improved by nearly two-thirds in patients who got the real ultrasound treatment — were published in the JAMA neurology and represent the headline result of the study.
Researchers tracked outcomes across 27 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with parkinson's disease, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
This treatment uses MRI-guided ultrasound to target a specific brain area without surgery. It is FDA-approved for essential tremor and Parkinson's tremor. If your tremors aren't controlled by medication, ask your neurologist whether you're a candidate for this procedure.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Exploring the Possible Beneficial Impact of Non-invasive and Invasive Neuromodulation on Freezing of Gait in Parkinson's Disease During Different Ambulatory Complexities: An Electrophysiological and fMRI Study
Freezing of gait (FOG) stands out as a devastating symptom of Parkinson's disease (PD), where patients may become momentarily glued to the ground, rendering them incapable of walking efficiently. The pathogenesis of FOG remains uncertain but is likely attributed to functional perturbations in superficial cortical and deep locomotion regions. FOG tends to manifest more prominently during complex walking, such as turning, than during simple straight forward walking, and the reasons for this phenomenon remain unclear. Unfortunately, effective methods for overcoming this ambulatory issue has yet to be identified, and quantifying paroxysmal gait spells proves challenging with clinical rating alone; thus, a scientific tool is warranted. In this 3-year proposal, the investigators plan to address these challenges comprehensively.
Exoskeleton-Assisted Mobility in Aging and in Parkinson's Disease
This study will evaluate whether a wearable robotic exoskeleton can improve mobility, balance, and walking in healthy older adults and in individuals living with Parkinson's disease, populations at high risk of falls and mobility limitations. Participants will attend two laboratory sessions. The first session includes clinical assessments, fitting and familiarization with the exoskeleton, and interviews to explore user perceptions. The second session involves performing functional mobility tasks (e.g., walking, standing, turning) with and without the exoskeleton and under different assistance levels, while movement is measured using wearable sensors. The study will assess the immediate effects of the exoskeleton on mobility, compare assistance levels, identify which participants benefit most, and explore user experience and acceptability. Findings will help inform the development and implementation of assistive technologies to support mobility in healthy aging and in individuals with Parkinson's disease.
