It may sound like something out of “Star Trek,” but the latest technology to treat patients with essential tremor is a true technological advance that Swedish helped research and now offers. ExAblate Neuro is a non-surgical technique that uses ultrasound to treat essential tremor, a neurological disorder that causes rhythmic shaking, most commonly in the hands, but also in the arms and legs.

On November 14th, 2013 the FDA gave its approval for an implanted brain stimulator to treat patients with medically refractory epilepsy. Epilepsy is one of the most common neurological disorders affecting nearly 1 in 100 Americans. This device has been under investigation for 10 years at the Swedish Neuroscience Institute (SNI) Epilepsy Center.

As principal investigator for the trial, I led  a team including Dr. Michael Doherty, Dr. Lisa Caylor and Dr. Alan Haltiner, along with the research department at Swedish to investigate the safety and effectiveness of the device through pivotal trials. The results showed that the responsive neurostimulator system (RNS) made by NeuroPace was indeed effective in treating patients with drug resistant seizures.

Why is this so significant? This device represents the first new non-medication treatment for seizures proven to be effective since 1997, and gives new hope to patients whose lives have been put on hold due to seizures. ...

Tremor is a normal physiologic reaction to anxiety or stress, but it is not normal to have a tremor when performing typical daily activities.


People who develop a tremor while eating, drinking, writing or doing other common activities may have a movement disorder called Essential Tremor. This is actually the most common movement disorder, and can affect up to 4% of people over age 40. People who have this disorder can take medications to help minimize the tremor, but they don't often reduce the tremor by more than about half. Deep brain stimulation (DBS) is an excellent treatment option for people with severe tremor, and can nearly eliminate the tremor in many patients. Many patients aren't sure when their tremor is severe enough to warrant surgery, and much of our conversation in the office is to help answer this question.

There is no one answer that is right for everyone, but for me it has to do with how well someone is actually doing in their daily life:


The Patient Rating score is based on responses given during the CAHPS Patient Experience Survey.Responses are measured on a 10 - point scale, with 10 being the best score. These scores are then translated to a 5 - point scale in order to display results in a 5 - star rating.Comments are also gathered from the same survey and displayed in their entirety with the exception of any language that may be considered slander, libel or contain private health information, which will be removed prior to publishing the comments.

4.4 out of 5 (54 Ratings, 13 Comments)


Provider and his office are great. All connections with Swedish Medical Center clerical and admin were needlessly complex, repetitious, and disorganized, tending to negate the positive impression of the actual medical treatment. Communication of appointment place and time were especially poor.

I am a retired physician, so I know what to expect, and the provider greatly exceeded my expections.

Second time for surgery with Dr. Gwynne we are expecting a similar successful outcome.

The doctor listened to me describe symptoms for a few minutes, announced he thought I had a terminal disease (ALS), would refer me to another specialist, then left, I've yet to hear anything from the new specialist, and referral states phone call messages have not yet been returned.

I don't think all my MRIs were read [...]. No symptoms were asked ? [...] No interest in discovery. HE IS PROBABLY VERY GOOD IN OTHER AREAS.

[...] I am having pain from a implant and I saw the Dr about it. I know it needs to be removed, but I was afraid because it was my safety blanket. The provider, for my sake told me that if I ever wanted to have it put back in it was okay to try again... He and I both know it the device will not work, but to show care and understanding of my fears; as a patient is amazing.... I have never been treated so kindly. He also knew that my ocular pain is from [...] after I explained my symptom.. for years I have told doctors this. He is the only one that caught on and referred me to a doctor to do a block. The provider is amazing and very knowledgeable; he should be recognized by Swedish

The majority of time was spent with his assistant; I think he's a PA. I would not recommend this MD because of the difficulty getting through to the office, lack of appointment times and surgery schedule.

He and his PA are awesome, very caring and concerned. Listen to what and had to saw and made a plan of action.

My wife and I were very comfortable with Dr. Gwynn. He was very easy to talk with and very informative. We appreciated the time spent with him. He did not make us feel like he was in any hurry. My appointment with Dr. Gwynn was the most satisfying experience I have had in a long time.

Recommend De. Gwinn for sure.

Since I wanted to discuss alternatives to surgery, I felt I was dismissed & given instructions to follow-up with another provider - who NEVER called, nor did Dr. Gwinn's office after multiple calls from me over 2 1/2 weeks - I'm still waiting.

I really appreciate Dr. Gwinn's kind help to us, listening, addressing our concerns, and showing thorough compassion.

Excellent doctor!
