 Transformative results that speak for themselves


"In the beginning, the first week or two, of using light therapy, I had an incredible breakthrough. I was like normal, absolutely normal. I had balance issues, real issues, but after(using the) SYMBYX I actually had a few days, a week, without any symptoms. Really everything was gone!

And I used to have problems with “offs” too. When I was 'On' everything was pretty good, when I was 'Off' suddenly nothing worked at all. I froze and I couldn't move at all. I was at the point of thinking about how much longer I can work and had considered quitting. And I could (quit) because I had reached retirement age and I could retire easily, but I didn't want that and now it's not an issue, not an issue at all!"

Dr Julie Christiansen has experience in research, including at Boston University and the Max Planck Institute. She has been using the PDCare laser since August 2022. Light therapy has helped her to continue her incredible work in neurolinguistics, helping rehabilitate individuals living with Parkinson's.


"After I received the Parkinson’s diagnosis in December 2020, I suffered from severe depression and slept very poorly. I introduced myself to three university clinics and three neurologists. Everyone told me to take medication. Besides NeuroEpo, which I started in December 2022, I’m still not taking any medication. After I’d done my own research on the Iinternet, I came across the PDCare Laser by SYMBYX and ordered it. A few weeks later I noticed the first improvements in my symptoms which I believe are attributable to the PDCare Laser. My mood is now very good again. My sleep has improved as well as my sense of smell. My left hand is more flexible and the muscle tension improved. All these symptoms were impacting my everyday life.

I hope that the PDCare Laser spreads quickly so that as many people as possible can experience the benefits of this therapy which has no side effects!

My symptoms are barely regressing since I first got diagnosed with PD in 2020. I now use the DuoCare 904, which reduces the treatment time of the PD protocol from 20 to 7 minutes. I bought this so I can treat the painful areas on my foot more flexibly, which start cramping after walking for 1 KM. On holiday I take my lighter PDCare with me. Many, many thanks to the SYMBYX Team for the ongoing and loving support".


As I am always open to new therapies, I wanted to try the PD Care Laser. After the initial consultation with SYMBYX, I knew that it would take some time before any noticeable changes would occur. The laser handling is simple, and the treatment can be performed without much knowledge. During the last few weeks, I have observed improved mobility & increased energy levels. It is definitely worth trying PD Care light therapy to find out how it can improve your personal well-being” says Stephanie, pictured.

Despite being instructed by my consultant not to google about PD - I did! And I came across the SYMBYX website. The message seemed positive, and I decided to order a PDCare. The SYMBYX laser seemed to be a good example of how technology could impact on Parkinson's symptoms. It was therefore not a difficult decision.

I noticed a change in symptoms about 6- 8 weeks after starting laser. There was a noticeable improvement with my resting tremor, possibly a 30-40% reduction. There was also a slight improvement in my sense of smell, although this can come and go. My speaking voice has also improved. Prior to using the laser I struggled, at times, to articulate things clearly....there was a “pregnant pause” before I could say what I wanted to. I have not allowed Parkinson's to impact negatively on my life.

Resting tremor is the symptom that irritates me most. I am hopeful that continuous use of the laser will further reduce the tremor – hopefully to zero, but if not then to a level where it’s more easily managed.

Approach new technology with an open mind. It's only by embracing new thinking that change takes place. However, it is important to accept that Parkinson’s is life changing and that there needs to be a discipline in the overall management of the symptoms. I believe that the SYMBYX laser should be part of a holistic Parkinson's protocol..


Jorge:“I had no energy, always felt tired. I also had dizziness, rigidity and balance issues when walking. I read some studies about photobiomodulation (or light therapy) and its effect on Parkinson’s disease. Everything made sense and I had nothing to lose trying this treatment, but many things to be hopeful for. Within a few weeks I started to notice change in symptoms. I noticed I had more energy and motivation; the dizziness and balance issues were also gradually disappearing."

Michèle:“He was so scared of falling, but now (after starting with SYMBYX) he walks fast and confidently. I can hardly keep up with him when we go hiking together! His general rigidity has subsided. I love seeing his beautiful smile every morning, and how happy, motivated and energised he feels. I believe hope is a very powerful motivator, especially when you’re dealing with an illness that is said to have no cure but a negative progression. Light therapy using the PDCare and SYMBYX Neuro (helmet) has given us a reason to be hopeful and dare to think of the future in a positive way. I was so afraid when my husband received his Parkinson’s diagnosis. He’s such a wonderful man and my best friend. I love him so much and can’t stand the idea of seeing him suffer and deteriorate. With PDCare and the results, we are achieving, there’s more and more reasons to replace fear with hope; we trust in science and in the wonderful people behind SYMBYX.”


After being diagnosed with Parkinson's over three years ago, I was determined to do whatever I could to keep my activity level where it was in the past for as long as I could. I continued with yoga classes, walking, and learned special exercise routines formulated for PD patients. When a friend told me about the light therapy treatments in Australia, I decided to check into it and am so glad I did. Within days of my first use, I noticed that constipation issues were improving markedly and have remained so over the three months I have used the SYMBYX PDCare. Gradually, I also noticed improvement in my energy level and the fine motor skills in my hands and fingers. I could type easier and faster and my longhand writing improved significantly. I also noticed improvement in smell and can taste food better - always a good thing!

I thought I would likely need to increase my medication dosage the next time I went to the neurologist - but since using the light therapy, I do not feel I need a higher dosage and have also noticed that I do not have any 'off times' between my medication doses. I feel optimistic and encouraged with my improvements, and the SYMBYX (light therapy) has contributed to that feeling!


"Even though I'm reasonably fit and play tennis three times a week or so, I have always had a lot of body niggles - including a tennis elbow that was often quite painful, especially after a long match. I have noticed a huge improvement in all these “niggles” after using the PhysioCare laser.

It’s so easy to use. I usually apply it for a couple of minutes around my elbow, or on my neck and shoulder area - wherever I feel a bit of inflammation. I find that I am totally pain free these days. It's fantastic"


In 2021 a friend, who had known of my enthusiasm for laser therapy, noticed an online report on the hand-held, battery driven SYMBYX laser. I immediately placed an order. After a month or two of using the laser therapy, the pain and discomfort in my back had reduced; the dull pain in my gut had become less of a concern; and I seem to suffer much less from the tremors in my arms and legs that are the bane of many people with PD.

The laser therapy is now an important component in the comprehensive list of things I do to contain my Parkinson's, and which also includes neuro-physiotherapy, strength training, voice therapy, stationary bike exercises, walking, and the course of tablets recommended by my neurologist. As a result, I am confident my Parkinson's Disease will be less restrictive on my lifestyle – and I feel I am better placed to get on with enjoying my life.

Everyone I spoke with from SYMBYX, including the Clinical Support Team provides excellent customer service, and took the time to answer all of my questions..


 "I bought the PDCare Laser because it had the advantage of being portable so I could use it anywhere, including at home. The feeling I had with the orthostatic tremor was sheer panic, like I was going to pass out. After using the PDCare it all went ! It was like a miracle to me. I am a very great fan of the device and the overall effects on people with Parkinson's. In my case, the tremor is virtually gone".

My fibromyalgia aches and pains have really improved, says Donna

"I have been using PhysioCare for over 2 months for my Fibromyalgia. I have noticed an improvement in the aching tenderness in my neck, shoulders and elbows. I use my SYMBYX light therapy device every day or so in the morning. After only a couple of weeks of using it I noticed that my aching/pain had really improved - my flare-ups are now less often. I really like how the PhysioCare is drug free. My rheumatologist and GP prescribed medication which I am reluctant to take as a lifelong treatment option. I had a recent Fibromyalgia flare up in my hip and noticed after using my PhysioCare an immediate improvement. It just didn’t feel as painful. Overall infrared light therapy has helped me manage my fibromyalgia symptoms much better than before”

Straight away his mood and sleep improved and he stopped getting nightmares, says Lucie from coastal NSW, Australia

"Before starting light therapy with SYMBYX, the main thing for (my partner) Paul was the off periods in Parkinson's. They were getting longer and his mood was getting worse.

Paul is a really active and energetic person and a sailor, so having to spendincreasing amounts of his time each day to deal with off periods was making him depressed. He felt like he couldn’t see a future. That’s where we were.This really concerned us because we thought things were just going to keep getting worse and worse, because doctors told us that’s what happens, that over time the effectiveness of the medication unfortunately wanes.

In February this year we started down the path of investigating Deep Brain Surgery at the same time as looking around for therapies that might supplement his meds and enhance their effectiveness. A friend saw an article about light therapy in The Australian newspaper which told how treating the gut microbiome was providing relief for some people with Parkinson’s.

After the first session with SYMBYX, Paul got an amazing result - immediate relief from constipation. After subsequent sessions (using the PDCare Laser at home) I would describe the results as astounding. Straight away his mood and sleep improved and he stopped getting nightmares. When he gets nightmares they are accompanied by involuntary movements/thrashing about. These went straight away. This was good for him and me - as I sleep with him!

He used to wake several times each night and be unable able to get back to sleep. Now he typically sleeps from 10PM - 6AM.When Paul was a having a bad day and loads of bad broken sleeps he wasn’t up for socializing or doing other things he used to enjoy and this affected both of us. That he is having far less bad days/nights now means we have rediscovered our social life and that works for both of us. It’s also true to say I am also sleeping better because he is no longer thrashing around so it’s a win-win as a couple.

Having many more better days means we can do all the things we love – sailing, boating, spending time with our family and friends like everyone else does. Before light therapy Paul was having half an hour off time every three hours. This is no longer the case. In fact, he recently forgot to take his meds at 3.30 PM and again at 6.30 PM and at 8 PM we were sitting down playing cards when he realised. We couldn’t believe it! He usually is just waiting for the next pill.

What would I say about light therapy to others? Grab light therapy with both hands. It’s a no brainer. What we like is that it’s not invasive. There are no chemicals involved so you’re not adding to an already long list of meds. It’s not hazardous and there aren’t any big hoops you have to jump through. For us the results were immediate. That’s the absolute truth! We didn’t need to wait 3 months. This might not be the case with everyone but there’s no downside in trying light therapy so give it a go!”

Light therapy improved the apathy and initiative of my husband with Parkinson's

"It's been 5-weeks since Rob, my husband, started using SYMBYX's PDCare. We've found it very easy and non-invasive, particularly during the Covid-19 lockdown. It's now part of our morning routine. I have noticed a significant turn-around in Rob’s general apathy from prior to starting the treatment. He can now do what is asked of him much more easily. He uses more initiative around the house, and has gone back to listening to his favourite music. His voice is stronger and he is sturdier on his feet when he exercises.Rob is now walking without right foot drop, with increased pace and more upright. Since treatment began, he is also more inclined to say 'Yes' rather than 'No' when asked a question or to participate. He is generally more animated and makes more attempt to challenge himself like trying small jogs during our daily walks. He dresses and shaves more easily. Rob is even initiating conversation again, especially when talking on the phone and is more willing to complete simple tasks such as sending emails and keeping his calendar current."

I have more energy since starting infrared light therapy for my Parkinson's, says Anna from England

"I believe it (light therapy using the PDCare) has had a very positive impact on me and my symptoms over the last few months. I have felt more energetic and less tired, very clear-headed and I believe I'm moving better than before. I'm definitely running faster.

I also definitely have less stiffness in my right arm and fingers. It seems to further enhance the impact of my PD medication."

Grace with Fibromyalgia, shares the PDCare Laser with her husband who uses light therapy for his Parkinson's

My husband and I have both been using the PDCare for a few weeks now. Me for my Fibromyalgia (which I have had for 16 years) and Harvey for his Parkinson's which was diagnosed 5 months ago. We have noticed a difference. My fibromyalgia has subsided. I also use on my arthritic joints, ankles, wrists, thumbs and lower degenerative back.

Harvey's hand shakes are less and he seems to be a lot more alert! He has also mentioned that his sense of smell has improved.

The PDCare is easy to use. We are excited to see how our body responds in coming months. Here's to a wonderful product!"


"I am a retired GP (Doctor of General Medicine) and have had PD for about four years. I have been using the PDLaser according to the SYMBYX protocol for 12 weeks and have improved in many ways.

I am sleeping better and stopped dribbling on the pillow at night. Also getting up to the toilet less often, if at all. My walking has improved, and balance, and sense of smell seem better. I still have a tremor at times but my voice is stronger. I am continuing my usual medication. My Neurologist says if it works to continue using the (PDCare) Laser. I attend PD warriors each week with some friends and do exercises at a gym 3 times a week also.

"PD device has been amazing in helping me with my Parkinson’s, I have still the trembling, but not anything like the whole body shaking which meant having to have a walker or stick close at hand. Thank you so very much, it’s been a life saver."

"I have found that my sleep time has increased from an average of 4 hours per night to six hours and of late I have slept 8 hours, I have also noticed that my constipation seems to be lessening. This has started after almost 8 weeks of use…"

“I definitely feel that I move more freely since I have been using the SYMBYX Biome. Also, I feel that my gut is acting a little more gently. I am very happy with it. My husband is borrowing it to use on his arthritic hands and he has also noticed an improvement.”

"I feel with steady use I’m seeing some improvements in tremor more in control. Noticing it when I do crosswords and other puzzles; my printing much more legible. Also balancing that I do during workouts; I’m holding balance on one leg and they can be held a few seconds longer."

"I have had significant improvement in my walking. My gait is much smoother making walking enjoyable again. First time in 11 years." Brodie

“I have used the laser for 3 months and have noticed a big improvement in flexibility and posture. I can think more clearly and can play scrabble again instead of being very slow to have a turn. l look forward to having my fibromyalgia symptoms disappear or improve too.” Wendy

“After six weeks the tremor that remained with Madopar medication has disappeared. My walking has greatly improved - faster and more fluid. My energy level has returned to close to normal - my morning “slump” has gone. My sense of smell has improved.” 


"Have noticed and improvement in balance and movement and my wife says the hands are steadier. "

"After using the PD laser for 9 weeks I have seen noticeable improvements especially with stiffness in hands and legs early morning and late at night. The 'dips' in symptoms between medications is less pronounced. I seem to feel more energetic.”
