An FSA (Flexible Spending Account) and an HSA (Health Savings Account) are tax-advantaged accounts for medical expenses but differ in key aspects. FSAs, employer-sponsored, allow employees to use pre-tax dollars for medical expenses such as prescriptions and copays, but typically feature a "use-it-or-lose-it" policy where funds must be used within the plan year. HSAs are available to those with a high-deductible health plan and offer more flexibility, allowing funds to roll over annually.

The MOVE+ is specifically designed to help relieve knee pain, whether it’s caused by arthritis, injury, or overuse. Using clinically proven red and infrared light wavelengths, the MOVE+ targets inflammation deep within the joint, improves circulation, and supports the body’s natural healing processes. Many users report reduced pain, better mobility, and less stiffness within weeks of consistent use. Whether you’re dealing with chronic discomfort or recovering from strain, the MOVE+ offers a safe, non-invasive option to support long-term knee health.

Red light therapy has been shown to significantly reduce pain and improve mobility in people with knee osteoarthritis. In a 2019 meta-analysis, they concluded that light therapy significantly reduces pain and disability in knee osteoarthritis patients when compared with placebo - even during follow-ups 1-12 weeks later.

The MOVE+ uses the same clinically validated wavelengths to target inflammation, support joint health, and provide long-lasting relief from chronic pain.

Red light therapy is non-invasive, drug-free, and considered very safe when used as directed. Most people experience no side effects at all. Unlike painkillers or invasive treatments, it works gently with your body to reduce inflammation and support healing, without causing harm or discomfort.

The MOVE+ works by delivering powerful red and near-infrared light deep into your joints and tissues, where it stimulates cellular repair, reduces inflammation, and promotes blood flow. This light energy penetrates below the skin to reach the damaged or inflamed areas, encouraging your body’s natural healing processes at a cellular level. As a result, users often experience reduced pain, improved joint mobility, and faster recovery from injury or overuse.

The MOVE+ is built on decades of clinical research into red and near-infrared light therapy. These wavelengths have been scientifically shown to reduce inflammation, relieve pain, and support tissue repair. The technology behind MOVE+ is trusted by physical therapists, athletes, and healthcare professionals worldwide.

Unlike many red light devices that use low-power LEDs or treat only the skin’s surface, the MOVE+ delivers clinically effective wavelengths using laser diodes that penetrate deeper into joints and tissues. It’s also fully portable, adjustable, and designed specifically for targeted pain relief — no bulky panels or complicated setups. You get precise, medical-grade treatment at home, with none of the hassle.
