What Is FlexBeam?
The FlexBeam is a wearable, portable red light therapy device manufactured by Recharge Health, a company founded in 2018 and headquartered in Norway. Unlike large red light therapy panels that require you to stand in front of them, the FlexBeam red light therapy device wraps around your body using velcro straps, allowing targeted treatment of specific problem areas.
What sets the FlexBeam apart from many consumer devices I've evaluated is its clinical-grade power output. Many cheap red light devices on the market simply don't deliver enough energy to penetrate tissue effectively. The FlexBeam delivers 110 mW/cm², which is within the therapeutic range supported by research.
Key FlexBeam Facts:
- • Developed by Dr. Zulia Frost using NASA-derived technology
- • Used by 35,000+ customers in 100+ countries
- • Trusted by elite athletes including tennis champion Casper Ruud
- • 4.7/5 rating on Trustpilot with 450+ reviews
The FlexBeam's flexible design allows it to wrap around various body parts
The Science Behind Red Light Therapy
As a healthcare professional, I don't recommend any therapy without understanding the research behind it. Photobiomodulation (PBM)—the scientific term for red light therapy—has been studied extensively over the past 50 years, and the evidence is compelling.
How Photobiomodulation Works
According to a comprehensive review published in the journal AIMS Biophysics, photobiomodulation works by stimulating cytochrome c oxidase in the mitochondria, which increases ATP (cellular energy) production. This triggers a cascade of beneficial effects including reduced inflammation, improved circulation, and accelerated tissue repair (Hamblin, 2017).
What the Research Shows:
- A 2023 review in the European Journal of Physical and Rehabilitation Medicine found PBM effective for musculoskeletal pain control (PMC9980499)
- Meta-analysis showed PBM can reduce pain intensity in knee osteoarthritis patients (PMC10531845)
- Clinical trials demonstrate significant improvements in fibromyalgia pain severity (PMC12326686)
Optimal Wavelengths:
Research has identified specific wavelengths as most effective for therapeutic applications:
Red Light (600-670nm)
Penetrates 2-3cm. Best for superficial tissue, skin health, and surface inflammation.
Near-Infrared (800-850nm)
Penetrates up to 10cm. Best for deep tissue, joints, muscles, and bone.
From the Research:
"Photobiomodulation therapy applied in the form of low-intensity LASER and LED has been shown to reduce inflammation and swelling, promote healing, and reduce pain for an array of musculoskeletal conditions."
— European Journal of Physical and Rehabilitation Medicine, 2023

Why I Recommend FlexBeam to My Clients
In my clinic, I see clients struggling with chronic pain every day. While manual therapy is incredibly effective, the benefits can fade between sessions. That's why I'm always looking for evidence-based tools that clients can use at home to maintain and extend their progress.
Who I Recommend FlexBeam For:
- Chronic pain sufferers: Clients with persistent back, knee, or neck pain who need daily therapy between clinic visits
- Athletes and active individuals: Anyone looking to speed recovery after training and reduce muscle soreness
- Post-surgical patients: Those recovering from joint surgery who want to support the healing process
- Desk workers: Clients with repetitive strain and tension from prolonged sitting
The FlexBeam can be used on multiple body areas including back, shoulders, and joints
My Clinical Perspective:
What I appreciate about the FlexBeam is that it bridges the gap between professional treatment and home care. The power output is strong enough to be therapeutic (not just a gimmick), and the targeted design means clients can address specific problem areas. I see it as a complement to—not a replacement for—professional therapy.
FlexBeam for Back Pain
Lower back pain is the most common complaint I see in my practice. Research supports the use of photobiomodulation for chronic low back pain—one study found that laser photobiomodulation was more effective than ultrasound therapy for patients with chronic nonspecific low back pain (Lasers Med Sci, 2019).
Why I Recommend FlexBeam for Back Pain:
- Deep penetration: The 800-850nm NIR wavelengths reach deep lumbar muscles and tissues (up to 10cm)
- Flexible design: Wraps across the lower back to cover the entire lumbar region
- Consistent dosing: 10-minute preset programs deliver a reliable therapeutic dose
- Hands-free: Clients can use it while relaxing, reading, or watching TV
Recommended Protocol:
Position FlexBeam horizontally across the lower back using the body strap. Use Program 2 (medium intensity) once daily for 10 minutes. Best results typically seen with consistent use over 2-4 weeks.
For more information, see my comprehensive guide on red light therapy for back pain.
FlexBeam for Knee Pain
Knee osteoarthritis affects millions of people, and the research on photobiomodulation for this condition is particularly strong. A systematic review found that PBM can reduce pain intensity and may improve disability in knee osteoarthritis patients (PMC10531845). Another landmark meta-analysis of 88 trials concluded that low-level laser therapy was effective for knee osteoarthritis (Brosseau et al., 2000).
Why FlexBeam Excels for Knee Treatment:
- Wrap-around design: The flexible 3-pod configuration conforms perfectly to the knee joint
- Joint penetration: NIR light reaches the joint capsule, synovium, and cartilage
- Anti-inflammatory effect: Research shows PBM reduces inflammatory markers like PGE2
- Secure fit: Velcro straps keep the device in place during treatment
I often recommend FlexBeam to clients with knee osteoarthritis, meniscus issues, or post-surgical knee pain as a complement to their rehabilitation program.

From the Research:
"Low level light therapy for osteoarthritis and rheumatoid arthritis showed pain attenuation of up to 90% in some studies, along with increased cellular rejuvenation and blood flow."

FlexBeam for Neck Pain
Cervical pain and stiffness are increasingly common in our screen-dominated world. Research has demonstrated the efficacy of low-level laser therapy for cervical osteoarthritis (Ozdemir et al., 2001), and the principles apply to the broader category of neck pain.
FlexBeam can be positioned across the posterior neck and upper trapezius
Using FlexBeam for Neck Pain:
The FlexBeam's flexible design allows it to drape across the posterior neck and upper shoulders—a common area of tension for desk workers and those with forward head posture.
- Placement: Position across posterior neck and upper trapezius
- Program: Start with Program 1 (gentlest) for the neck area
- Frequency: Daily use, particularly after long periods of computer work
Important:
Do not use FlexBeam directly on the front of the throat or over the thyroid gland. Always position it on the back of the neck only.
