Red Light Therapy for Hand Pain: What the Research Shows, Cause by Cause

Red light therapy for hand pain has its clearest support in rheumatoid arthritis of the hands, where a Cochrane review of 5 trials with 222 people found less pain and 27.5 minutes less morning stiffness in the short term. Small studies add early signals for finger joints, the thumb base and hand tendons. Below: the evidence cause by cause, trial settings, splints and exercise, warning signs, and how to set up a panel for both hands.

Key takeaways

• A Cochrane review of 5 trials with 222 people, mostly treated on the hands, found rheumatoid arthritis pain 1.1 points lower on a 10-point scale with laser light than with placebo in the short term. Brosseau, 2005
• In 23 people with finger joint osteoarthritis, 850 and 940 nm LED light twice a week for 4 weeks was followed by pain falling 38.17 points from 72.78 on a 100-point scale, in a study without a control group. Kim, 2024
• In 12 women with hand tendon pain not helped by anti-inflammatory tablets, 850 and 592 nm LED light twice a week for 4 weeks was followed by pain 1.88 points lower on a 10-point scale at week 8. Choi, 2023
• In a triple-blinded trial of 43 people with arthritis at the base of the thumb, a high-intensity clinic laser lowered pain more than placebo at the end of treatment and at 12 weeks. Cantero-Téllez, 2020

Does red light therapy for hand pain work?

For several common causes, the research points to short-term relief of pain and stiffness, with the strongest evidence in rheumatoid arthritis. How much it helps depends on the cause, so start by knowing which problem you have.

Hand joints and tendons sit close to the skin, within easy reach of red and near-infrared light. Most trials used clinic lasers on the skin; a few used LED probes.

Cause	Typical signs	Closest light evidence	Where to aim
Finger joint osteoarthritis	Aching, stiff fingertip or middle joints, bony bumps	LED study, 23 people, no control group	Palms, then backs
Thumb base arthritis	Pain where the thumb meets the wrist, worse when gripping	Placebo-controlled trial, 43 people, clinic laser	Thumb side and base of the thumb
Rheumatoid arthritis	Swollen, stiff joints in both hands, long morning stiffness	Cochrane review, 5 trials, 222 people	Both hands, palms then backs
Tendon pain (tenosynovitis)	Pain and stiffness along the tendons of the palm and fingers	LED study, 12 women, no control group	Palm open towards the light
De Quervain's	Pain on the thumb side of the wrist	Laser trial, 28 people (30 wrists)	Thumb side of the wrist
Trigger finger	A finger that catches or locks, tender palm at its base	Case reports and a trial under way	Palm side at the base of the finger
Carpal tunnel syndrome	Tingling or numbness in the thumb and first fingers, worse at night	Cochrane review, 22 trials, 1,153 people	Palm side of the wrist

Each cause has its own guide: red light therapy for trigger finger, red light therapy for carpal tunnel and red light therapy for wrist pain, which covers de Quervain's. Our hands and feet guide also covers cold hands and Raynaud's.

Can red light therapy for hand arthritis ease stiff finger joints?

The closest evidence is a small LED study in finger joint osteoarthritis, where pain about halved over 4 weeks. It had no control group, so it is an early signal.

In the study, 23 adults with hand osteoarthritis had a high-density LED probe at 850 and 940 nm on their five most painful finger joints. Kim, 2024 Sessions lasted 18 minutes, twice a week for 4 weeks.

Pain started at 72.78 on a 100-point scale. It was 38.17 points lower at week 4 and 41.22 points lower at week 6, with no side effects.

Ring size and range of motion did not change, so the benefit was comfort, not smaller joints. Those are the fingertip and middle joints where bony Heberden's and Bouchard's nodes form. Arthritis Foundation, 2021 See our arthritis guide for other joints.

Can red light help arthritis at the base of the thumb?

The closest evidence is a placebo-controlled trial in which a high-intensity clinic laser lowered thumb base pain more than placebo. That was a clinic laser, not a panel, so the pattern carries over rather than the dose.

The trial included 43 people with an average age of 71 and early thumb base arthritis. Cantero-Téllez, 2020 Pain fell more with the laser at the end of treatment and again at 12 weeks.

"Pain is the first and most common symptom of thumb arthritis." Mayo Clinic Women are 2 to 3 times more likely to develop it, and it is most common after 50. AAOS

Standard care comes first: a splint during activities or overnight, ice for 5 to 15 minutes several times a day, anti-inflammatory medicine, and sometimes an injection or surgery. Light can sit alongside that plan. Turn the hand on its side so the thumb side and the base of the thumb face the panel.

Does red light help rheumatoid arthritis in both hands?

Yes, in the short term: the Cochrane review found less pain, shorter morning stiffness and better finger bending with laser light than with placebo. Light sits alongside the medicine a rheumatologist prescribes, never in its place.

The trials treated people 2 to 3 times a week for about 4 weeks, mostly on the hands. Brosseau, 2005

• Pain: 1.1 points lower on a 10-point scale.
• Morning stiffness: 27.5 minutes shorter.
• Flexibility: fingertip to palm distance 1.3 cm better.

The authors concluded that light "could be considered for short-term treatment for relief of pain and morning stiffness". A 2024 review of 22 studies found better grip strength and less morning stiffness with laser light. Salajegheh, 2024

Rheumatoid arthritis is "almost always symmetrical", so treat both hands together. Arthritis Foundation, 2022 During a flare, with hot, swollen joints, call your specialist before using light. Our joint pain guide covers other joints.

Can red light help tendon pain in the hand when anti-inflammatories have not worked?

A small LED study suggests it may: in 12 women whose hand tendon pain had not eased with anti-inflammatory tablets, pain and stiffness fell over 8 weeks. There was no control group, so treat it as an early signal.

The women had tenosynovitis confirmed by a rheumatologist. Choi, 2023 They had 850 nm near-infrared with 592 nm amber LED light for 20 minutes, twice a week for 4 weeks.

• Pain: 7.00 out of 10 at the start, 1.33 points lower at week 4 and 1.88 lower at week 8.
• Stiffness: 1.25 points lower at week 8.
• Safety: no side effects.

Relief kept improving for four weeks after the last session.

For de Quervain's, on the thumb side of the wrist, a placebo-controlled laser trial in 28 people (30 wrists) found better grip and pinch strength. Sharma, 2002

Is it carpal tunnel rather than arthritis, and where do you aim?

Carpal tunnel is a nerve problem at the palm side of the wrist, so the light goes there rather than on the finger joints. A Cochrane review of 22 trials with 1,153 people found pain 1.47 points lower than placebo in the short term, with very low certainty.

The same review found grip strength 2.58 kg better in the short term. Rankin, 2017 Keep any night splint, and give a routine up to five weeks before judging it.

Carpal tunnel brings numbness, tingling and "sometimes electric shock-like pain", often worse at night, while arthritis brings morning stiffness, swelling and an aching joint. Arthritis Foundation, 2022 People can have both, so get a diagnosis, and see a GP first for numbness that does not go away.

What settings did the hand pain trials use?

Most used near-infrared light, often with a visible wavelength, about twice a week or more for about 4 weeks. The LED studies ran 18 to 20 minutes per session.

Study	Problem	Light	Minutes	Sessions per week	Weeks
Choi, 2023	Hand tendon pain	850 + 592 nm LED	20	2	4, follow-up to week 8
Kim, 2024	Finger joint osteoarthritis	850 + 940 nm LED probe	18	2	4
Brosseau, 2005	Rheumatoid arthritis, mostly hands	Various lasers	Varied	2 to 3	About 4
Sharma, 2002	De Quervain's	Laser, 2 to 4 J/cm² per area	Not stated	Not stated	Up to 10 sessions

The laser therapy association WALT suggests 4 J for a finger joint, daily for 2 weeks or every other day for 3 to 4 weeks. WALT, 2010 Laser joules per point do not convert into a panel session. What carries over is the pattern: near-infrared, small joints, regular sessions for several weeks, alongside splints, exercise or medicine.

Do red light gloves work, or is a panel better for hands?

The hand studies used clinic lasers and LED probes held on or near the skin, not gloves or panels. Whatever the format, look for stated wavelengths, a stated output and a schedule you can keep.

Gloves wrap around the hand and let you move about. A panel lights both hands at a set distance, turned to reach the palms, backs or thumb side, and also reaches wrists, elbows and knees.

Can you combine red light with splints, hand exercises, heat or ice?

Yes, as separate steps: keep your splint as advised, use light first, then do your exercises while the hand feels easier. Keep ice, heat and light as separate sessions.

• Splints: the NHS advises a thumb splint "especially at night". NHS, thumb pain A night splint leaves the day free for sessions. Never remove a splint, cast or brace to use light.
• Exercise: NICE names "therapeutic exercise and weight management" as the core treatments for osteoarthritis. NICE, 2022
• Heat and cold: both are listed options for hand osteoarthritis. Arthritis Foundation, 2021 Avoid heat packs and hot baths for the first 2 to 3 days after an injury. NHS, finger pain
• Heating pads: never use a heating pad and the panel on the same skin at the same time.

After a steroid injection, ask the clinician who gave it before using light. After hand surgery, wait until the wound has fully closed and your surgeon agrees, and ask the surgeon first if you have metal implants.

Which hand symptoms need a doctor before trying light?

Get urgent help after an injury with a snap or grinding noise, a changed shape or colour, lost feeling, or a hand you cannot use. A hot, red, swollen joint with a high temperature also needs urgent care.

• Urgent: severe pain, or feeling faint or sick after an injury. NHS, thumb pain
• Emergency: a finger that suddenly will not move, or a red, swollen finger that hurts to straighten, especially after a cut or bite.
• See a GP: tingling or numbness, diabetes, or pain that "has not improved after treating it at home for 2 weeks". NHS, finger pain
• Inflammatory arthritis: morning stiffness lasting more than 30 minutes, or swelling in several joints, should be assessed.

Our precautions rule the panel out during pregnancy, breastfeeding or preparing for pregnancy, when de Quervain's and carpal tunnel are common. They also rule out epilepsy or seizures triggered by light, a thyroid condition or thyroid medication, broken skin on the area, sunburn on the body in the past 2 weeks, Fitzpatrick skin types V or VI, and use while asleep.

Ibuprofen and naproxen, common hand pain medicines, appear on lists of medicines that can make skin more sensitive to light. Our precautions rule out photosensitising medication, so if you take any medicine, check with your pharmacist or doctor before using the device.

How do you use a Kivorla panel for hand pain?

Set the panel at table height, put the goggles on, close your eyes, and rest your forearms in front of it with both hands about 6 inches away. Run 10 to 15 minutes on the palms, then the backs, two to five times a week.

The 9-Spectrum Red Light Therapy Panel carries 480, 590, 630, 660, 670, 810, 830, 850 and 1060 nm, each dimmable from 1 to 100%. Its 850 nm channel matches the near-infrared in both hand LED studies. The mask is for the face only.

• Mounting: hang it on a door or wall with the included door hook, pulley, hanging cables and screws, or stand it upright on the floor. Its 640 by 230 mm face lights both hands side by side.
• Skin: clean and bare, rings off, hands off the panel.
• Finger joints and rheumatoid arthritis: palms first, then backs, both hands.
• Thumb base: hand on its side, thumb side towards the light.
• Tendon pain or trigger finger: palm open, base of the fingers facing the panel.
• Channels: 810, 830 and 850 nm high; 670 nm on; 630 and 660 nm lower or optional; 1060 nm optional; 480 and 590 nm at their lowest or off.
• Timer: set 10 to 15 minutes; if no time is set, the panel stops at 5 minutes. The surface stays at or below 40°C.
• Warmth: warm is fine, hot means stop. Numb fingertips may not sense warmth, so keep sessions short and check the skin afterwards.
• Log: pain out of 10, minutes of morning stiffness, and one task that hurts, such as opening a jar.

To stay closer to the small doses in the trials, turn each wavelength down from 100%, set a shorter timer (it starts at 1 minute), or step back to 12 inches. Leave at least 6 hours between 30-minute sessions, and judge it after three to four weeks, or up to five for carpal tunnel.
