Patient FAQs

What is laser therapy?
Laser therapy is the use of specific wavelengths of light to treat conditions in the body. Our MLS laser was specifically designed with particular wavelengths to treat pain and inflammation.
What does MLS stand for?

Multi-wave Locked System. Our patent laser device uses 808nm and 905 nm wavelengths at the same time in a locked delivery system. The wavelengths fire at the same time to promote better healing and faster results.

What is “Cold Laser”?
When laser therapy was first introduced, it was nicknamed “cold laser” to distinguish it from other lasers that cut or burn the skin like those used in surgery. Laser therapy is a medical treatment that uses specific wavelengths of near infrared (NIR) light to promote tissue healing, relieve pain, and reduce inflammation and swelling. The lasers aren’t actually cold, they simply don’t generate perceptible heat. Cold laser generally referred to older lasers that are typically Class III devices. MLS is a highly more advanced Class IV robotic laser device that doesn’t generate perceptible heat.
How does it work?
The two wavelengths our laser emits safely penetrate through the skin and are absorbed by tissues and cells in the body. The energy is used by mitochondria (organelle in the cell) to create cellular energy called ATP. The laser also brings blood flow to the treatment area, which brings with it oxygen and nutrients.
How long does a treatment take?
Average treatment time is approximately 10 minutes with the laser. Depending on your condition, you may have a shorter or longer time under the laser to achieve the optimal treatment application.
How many treatments will I need?
Based on your condition, your doctor will be able to recommend proper treatments. Common treatments are either 6 visits (acute condition) or 10 visits (chronic condition). Laser therapy is cumulative and builds on previous sessions, much like taking an antibiotic. Most patients experience a gradual improvement in their pain and inflammation as the laser treatment plan progresses. Therefore, it’s important that you complete the entire course of treatments recommended by your doctor. If you discontinue the treatment prior to completing the entire course of care, your symptoms are likely to reoccur.
What can I expect during treatments?
MLS M8 Laser Therapy treatments are painless, and most patients don’t feel any sensation during treatment. The laser needs to shine directly on your skin so wear lose, comfortable clothing that you can adjust if needed. The office will also be able to provide disposable gowns or shorts if necessary. Most patients will be seated or lying down for their treatment. We will do our best to ensure your comfort throughout the entire treatment. Our staff is specifically trained to ensure optimal patient outcomes and comfort.
What can I expect after treatments?
We recommend patients go about their lives like normal after laser therapy. However, since the laser decreases pain, don’t jump into too much activity too fast that your body isn’t ready for. Also, avoid icing the area for at least 8 hours after the completion of your visit. If you have a scheduled Physical Therapy, Chiropractor, Occupational Therapy, etc. visit, we recommend you keep your scheduled care with them as well. If you have any questions, please ask us!
Are there side effects?
Like any medical intervention, laser therapy has potential possible side effects, and each person may respond differently. However, there are currently no known side effects with MLS Laser Therapy.
What is MLS M8 Robotic Laser Therapy FDA- cleared for?
MLS M8 robotic laser therapy is FDA cleared for the relief of pain, inflammation, and swelling.
Is MLS covered by my insurance?
No, MLS Laser Therapy is not covered by insurance. We take flexible spending (for example HSA & FSA).

I developed pain in my tibia after training for a half marathon, likely a shin splint or stress response. I was trying to do the usual remedies for this situation but I still had pain and I work in a hospital on my feet all day. Dr. Sigman advised me to try Ortho Lazer to reduce pain more efficiently and quickly. After 2 treatments I was able to bear weight without pain and the day after my 5th treatment I stood in the operating room working for 12 hours straight without sitting and my shin didn’t hurt at all!!! I would recommend this treatment for anyone with my condition, or anyone suffering from a painful orthopedic condition because it truly worked wonders for me!!

Middle aged Ladies and Gentleman who LOVE to stay active with sports and exercise while grinding through the agony of those bumps, bruises and aches, just because you don’t want your spouse to know it “may be time to hang em’ up” or the fear of making an appointment to see the doctor.....this post is for you!OrthoLazer may just be the modern fountain of youth! I was battling reoccurring swelling/pain in one knee. It would show up every 4-6wks like clockwork and take a solid 2 weeks to go away. 2 weeks of constant aspirin, ice, rest. My love for sports would always put me right back into the same cycle I’m sure many 40 year olds face all too often. I heard about OrthoLazer from a friend who had some great success with knee pain he was dealing with too. I made the appointment the next day. The process could not have been any simpler! Staff was amazing as they walk you through a brief 6-8min consult, take you into a room where you’re zapped with a laser (10min’ish) that you can’t even tell is on, and in 20min you are back on your way. I couldn’t squat down due to the swelling in my knee and after the 2nd treatment (48hrs- I went back to back days) I had full range of motion. I completed 6 total treatments and was back pitching after the 4th treatment. This was back in Aug and here I am in Feb after playing summer baseball, fall soccer and some basketball during the winter, completely pain free and most importantly free from that vicious cycle that I had come accustomed to.BEST bang for your buck in terms of non invasive medical treatment options in my opinion. Stop putting up with the pain and try cold laser- IT WORKS!!!

It works! I've known Dr. Sigman for many years and admire his efforts to offer non opioid alternatives to treating chronic pain. Whether post surgery, arthritis or other reasons to treat your pain....give Ortho Lazer a try. I have arthritis in my hip and it definitely effects my quality of life. Not quite ready to do hip replacement. After 10 sessions, my pain is virtually gone. The staff at Ortho Lazer is friendly, helpful and professional. Keep up the good work, and thank you!

I've had great results from my treatment at Ortho Laser.I was having hip pain that made it painful to walk and sleep at night.The first thing I noticed was less inflamation in my body.In the past I would have to get steriod injections when I had a lot of inflamation.After just a few laser treatments my hip was feeling so much better !Since I also have back problems, I asked to have my back added to my treatment plan.It didn't take long before I was finally pain free and in less time than anticipated.I'm so glad that I gave this a try.It's so nice to finally be able to do things without being in pain, as well as sleeping at night.I highly recommend Ortho Laser.It works and the staff is incredible !

If you’re not sure about Ortho Laser I encourage you to try it. The treatment is really quick, completely painless and very effective. There is one down side- it isn’t covered by insurance. However, I would note that what I achieved in three sessions would have taken much longer with conventional Physical Therapy. Overall, I saved money, time and returned to my life much sooner with the help of this treatment.

My experience with the Ortho Lazer has been great. I have severe knee problems and so far so good. I have recommended this treatment to my coworkers. I think this type of treatment should be covered by insurance because it helps heal your Ortho problems without opioids. Would highly recommend trying this because you have nothing to lose and everything to gain.

I went to Ortho Lazer for an inflamed rotator cuff. Before my first treatment I could not lift my arm above my shoulder height. It was very weak and painful. I scheduled six treatments but my shoulder was much better after just three. I completed the six treatments in two weeks and my shoulder was completely pain free. It was amazing! I still need to work on building up strength but I can’t wait to try the laser on other aches and pains. I’m trying it next for my plantar fasciitis. I would definitely recommend this treatment to anyone with pain or an injury.

Amazing results with just 4 treatments. I did not experience any pain at all and actually felt great relief after my first visit!

I had constant pain in my right knee. I was skeptical at first of Dr. Sigmans recommendation of Ortholaser therapy. But, Dr Sigman had performed surgery on my left knee and it feels great. So I gave the Lasertherapy a try. I wanted to try to avoid surgery in the right knee. I had 10 sessions of laser therapy.My knee feels great! I can sleep on my side and I no longer have constant pain upon moving! Dr. Sigman and staff are so well versed and knowledgeable.I trust their judgment profusely! I am thrilled!

I like to let anybody who's interested or heard of Ortho Lazer it's a wonderful treatment I highly recommend it they've done wonders for my shoulder it's improving I am so thankful I'm grateful for this piece of technology thank you thank you thank you

Wonderful location, amazing staff as expected being operated by Dr. Sigman. I was a bit apprehensive as to how the treatment itself would work, not knowing truly HOW it works and having had such extensive knee surgery in March, but I trust Dr. Sigman with my life and I am not disappointed with the results after 10 sessions. My knee feels so much better. Thank you to everyone. I would absolutely return in the future if the need arose.~ Melissa S.

The results I got from the cold laser were nothing short of miraculous. By my 4th appointment, I felt close to 100 percent, and improved from there after every visit. I'm back at the gym working as I was before the injury, and couldn't be more pleased.

The decrease in the level of pain in my hip is amazing and I’m only 2/3 of the way through my treatments! I no longer suffer with constant discomfort and pain from arthritis in that joint. The best part is that I can lie on my left side again so I am sleeping much better!

I sprained my ankle on October 23rd. I started Laser treatments at Ortho Lazer the next day. After the third treatment, my swelling has diminished. It's a week later and I am 80% pain free! Cold Laser Therapy is amazing!
