Osteoarthritis (OA) of the hands is a common and often debilitating condition. It causes joint pain, stiffness, reduced grip strength and difficulty performing everyday tasks such as opening jars, typing or buttoning clothes. While traditional management often relies on pain medication, splints and exercises, many patients are seeking non-drug, non-invasive solutions.
Low-level laser therapy (LLLT), also known as photobiomodulation (PBM), has emerged as a promising option. By delivering gentle pulses of red and near-infrared light into affected joints, PBM reduces inflammation, improves circulation and supports tissue repair — easing pain and improving dexterity.
How laser therapy helps osteoarthritis
At the cellular level, PBM targets the mitochondria, the “powerhouses” of cells. Light absorption increases ATP (cellular energy), regulates oxidative stress and modulates inflammation. This biological cascade:
-
Reduces pain signalling by calming overactive nerve pathways
-
Lowers joint inflammation through anti-inflammatory cytokine effects
-
Promotes tissue repair by supporting cartilage metabolism and joint fluid balance
-
Improves hand mobility by easing stiffness and enhancing joint function
Clinical evidence for hand osteoarthritis
Research supports the use of PBM for osteoarthritis of the hands.
-
Randomised controlled trial: A double-blind, placebo-controlled study investigated the effects of LLLT on patients with hand osteoarthritis. The results showed significant improvements in pain, stiffness and overall hand function compared to placebo.
-
Systematic reviews: Broader reviews of PBM in osteoarthritis confirm consistent pain reduction and improved function, particularly in small joints such as the hands.
These findings suggest that regular use of LLLT can be an effective adjunct therapy for people struggling with daily hand pain and loss of dexterity.
Key benefits for patients
-
Targeted pain relief: Direct application to the hands calms joint inflammation at its source.
-
Reduced stiffness: Easier morning movement and greater comfort throughout the day.
-
Improved dexterity: Better grip, strength and fine motor function for daily tasks.
-
Non-drug therapy: An alternative to painkillers and anti-inflammatory medications.
-
Safe and non-invasive: Minimal risks when used within recommended parameters.
Treatment approach
-
Frequency: Regular sessions (several times per week) are most effective in the first month, followed by maintenance use.
-
Wavelengths: Red light (630–680 nm) and near-infrared (800–850 nm) penetrate tissues to reach small joints.
-
Devices: The Pulsed Low-Level Laser Therapy unit is designed for at-home or clinic use, delivering safe and effective PBM protocols specifically suited for joint pain and osteoarthritis.
Safety considerations
LLLT for hand osteoarthritis is generally safe, with no reported major side effects in clinical trials. Precautions include:
-
Avoiding use over active skin infections
-
Consulting a healthcare professional before starting if pregnant or managing complex conditions
-
Ensuring correct use of certified medical-grade devices
Brighter Days for Hand Osteoarthritis
Laser therapy through photobiomodulation offers new hope for people living with hand osteoarthritis. By targeting pain, reducing stiffness and improving dexterity, it allows patients to reclaim everyday function without relying solely on medications.
For those seeking practical solutions, the Pulsed Low-Level Laser Therapy device provides an accessible, evidence-backed way to support joint health and hand mobility.
