Rheumatoid arthritis (RA) is an autoimmune condition in which the immune system mistakenly attacks the lining of the joints, causing inflammation, pain, stiffness, and over time, potential joint damage. For most people living with RA, the backbone of treatment is medication — disease-modifying antirheumatic drugs (DMARDs) and biologics that work to slow or halt that immune-driven process.
But medication is rarely the whole story. Between appointments, during flares, or simply on days when joints feel particularly uncooperative, many people find that physical tools — joint supports, splints, and transcutaneous electrical nerve stimulation (TENS) devices — offer a meaningful layer of comfort. Understanding what these tools can and cannot do helps you use them wisely, and helps you have a more informed conversation with your rheumatologist, physical therapist, or occupational therapist.
Why Non-Drug Approaches Matter in RA
RA management has come a long way, and today's medications are far more effective at controlling disease activity than those available a generation ago. Even so, many people with RA experience breakthrough pain, morning stiffness, or fatigue that medication alone doesn't fully address. Others have concerns about side effects or want to minimize medication doses where possible.
Non-drug strategies fit into this space. They don't change the underlying immune process, but they can help manage symptoms, protect vulnerable joints during activity, and support function — your ability to button a shirt, open a jar, or walk to the mailbox. That kind of functional support has real quality-of-life value.
Non-drug tools work best as complements to a well-managed medication plan, not substitutes for it. If your RA is poorly controlled, speak with your rheumatologist before relying on supports or TENS to mask pain that signals active disease.
Joint Supports and Splints: Stability When You Need It
Supports and splints are among the oldest and most widely recommended non-drug aids in RA care. Occupational therapists — specialists who focus on helping people perform daily activities — frequently prescribe or recommend them. There are several types, each suited to different situations.
Resting Splints
These are typically worn at night or during rest periods. They hold a joint — most often the wrist or hand — in a neutral, comfortable position. The goal is to reduce the strain on inflamed joint structures while you sleep, when you might otherwise curl your wrists in ways that worsen morning stiffness. Some research suggests that wearing resting hand splints can reduce pain and improve comfort, particularly during flares.
Working Splints and Functional Supports
Unlike resting splints, working splints are designed to be worn during activity. A wrist working splint, for example, stabilizes the joint while still allowing enough movement for everyday tasks. Knee sleeves and ankle supports serve a similar purpose for the lower body — providing gentle compression and proprioceptive feedback (a sense of where your joint is in space) that can make movement feel more controlled and less painful.
Compression gloves are a popular option for hand and finger symptoms. They apply mild, even pressure across the small joints of the hand. While the evidence on exactly how much they reduce pain is mixed, many people report that they ease morning stiffness and swelling, and wearing them is generally low-risk. Some people find warmth alone is part of the benefit.
Foot Orthotics and Shoe Inserts
RA frequently affects the small joints of the feet, making walking uncomfortable. Custom or over-the-counter orthotics can redistribute pressure away from inflamed areas, cushion painful spots, and improve gait mechanics. A podiatrist or physical therapist can assess whether inserts might help and whether a custom fit is worth pursuing for your situation.
Important Caveats About Supports
Splints and supports are not one-size-fits-all. A poorly fitted splint can increase discomfort, restrict circulation, or even alter the mechanics of adjacent joints in unhelpful ways. Equally important: wearing a support too often can lead to muscle weakness around the joint over time, which is the opposite of what you want. An occupational therapist can help you find the right fit, the right type, and a wearing schedule that protects rather than weakens the joint.
TENS Therapy: Using Gentle Electrical Current for Pain Relief
Transcutaneous electrical nerve stimulation — TENS — delivers small, low-voltage electrical pulses through electrodes placed on the skin near a painful area. It sounds more intimidating than it is; most people describe the sensation as a mild tingling or buzzing.
There are two main theories for why TENS may relieve pain. The first, sometimes called the gate control theory, proposes that the electrical signals compete with pain signals traveling along the same nerve pathways, essentially crowding them out before they reach the brain. The second involves the idea that electrical stimulation may encourage the release of the body's own natural pain-modulating chemicals, such as endorphins.
What the Evidence Says
Research on TENS for RA is generally encouraging, though the picture is nuanced. Studies suggest that TENS can reduce pain and, in some cases, ease hand grip difficulties — outcomes that matter a great deal to people whose hands are affected by RA. Effects tend to be modest and temporary rather than dramatic or long-lasting, which means TENS works best as part of a broader pain management approach rather than as a standalone solution.
It's also worth noting that most studies on TENS in RA have been relatively small or short in duration, so researchers continue to refine their understanding of which settings, electrode placements, and treatment schedules work best for whom. Your physical therapist or pain specialist can help tailor a TENS protocol to your specific pattern of symptoms.
Types of TENS Units
Conventional TENS units deliver high-frequency, low-intensity stimulation and are typically used for shorter sessions throughout the day. Acupuncture-like TENS uses lower frequency and higher intensity, and some people find it produces a deeper, longer-lasting effect. Portable, consumer-grade TENS devices are widely available without a prescription, but starting with guidance from a clinician — at least for your first sessions — helps ensure you're placing the electrodes correctly and using settings that are likely to help rather than irritate.
Who Should Be Cautious With TENS
TENS is generally considered safe for most people with RA, but it is not appropriate for everyone. People with pacemakers or other implanted electronic devices should avoid TENS, as the electrical signals can interfere with device function. TENS should not be used over areas of broken skin, rashes, or active infection, or directly over the front of the neck, eyes, or across the chest. Pregnant individuals should check with their provider before using TENS. Always read the device instructions and, when in doubt, ask your care team.
Putting It All Together: A Complementary Toolkit
The most effective RA care tends to be multimodal — combining disease-modifying treatment with physical and occupational therapy, activity modifications, and targeted symptom-relief strategies like supports and TENS. Here's a practical way to think about integrating these tools:
- During a flare: A resting splint can protect an inflamed wrist overnight. TENS may help take the edge off acute pain. Rest the affected joint, but try to keep other parts of your body gently moving to avoid stiffness.
- For daily activities: A working wrist splint or compression gloves may make tasks easier and less painful. Orthotics can help if foot pain is limiting your ability to stay active.
- For ongoing pain management: Regular TENS sessions, as directed by a physical therapist, can be scheduled around your routine. Track whether and how much they help so you can report back to your care team.
- For joint protection long-term: Ask an occupational therapist about joint protection techniques — strategies for doing everyday tasks in ways that minimize stress on vulnerable joints. Supports are most effective when used alongside these habits, not instead of them.
The Role of Your Care Team
RA care is most effective when it's coordinated. Your rheumatologist manages disease activity and medications. A physical therapist can address strength, movement, and TENS therapy. An occupational therapist specializes in hand function, splinting, and adapting daily activities. Together, they can help you find a combination of approaches that fits your life, your disease pattern, and your goals.
If you're interested in trying a support or TENS device and haven't already discussed it with your team, bring it up at your next appointment. Describe which joints bother you most, at what times of day, and during which activities. That detail helps your clinicians make specific, useful recommendations rather than generic ones.
A Realistic Perspective
Supports and TENS will not stop RA in its tracks — that's the job of medication and the immune system. What they can do is help you function better on difficult days, protect joints during vulnerable moments, and give you a sense of agency over your symptoms. For many people with RA, that sense of control, small as it might seem, is genuinely meaningful.
Living well with a chronic condition involves layering many small strategies on top of each other. Supports and TENS are two reliable tools in that toolkit — best used thoughtfully, fitted correctly, and embedded in a plan your care team knows about and supports.
