Every week, patients ask me the same question: “What should I actually buy?” There’s no shortage of answers online — compression gloves, splints, gadgets that promise relief in a headline. But not everything that’s popular has been tested. So I went back to the research — the 2019 guideline from the American College of Rheumatology and the Arthritis Foundation, along with the clinical trials behind it.
Hand exercises and therapy putty Strong evidence
Let’s start with the one that surprises people: exercise. Not just “stay active,” but specific, structured hand exercises — and something as simple as therapy putty, a soft, stretchy dough you squeeze to build hand strength. A review of hand exercise studies in rheumatoid arthritis found real improvements in grip strength, without making pain or disease worse. In the UK this grew into a full program called SARAH, now recommended in national guidelines.
Paraffin wax heat therapy Moderate evidence
You dip your hands in warm, melted wax, let it set, then peel it off. It sounds almost too simple, but randomized trials found it measurably reduced pain and improved grip and pinch strength — especially over several weeks, and especially paired with exercise. I tell my patients: a solid, low-cost addition. Not a replacement for exercise; a good partner to it.
Thumb splints Mixed evidence
Here’s where I want to be honest with you, because this one surprised even me. The most rigorous trial we have — 349 people in OTTER II — found that adding a thumb splint on top of a good exercise program didn’t add extra benefit. A splint can still help you get through a flare. Just don’t expect it to replace the exercises above. Backup, not the main plan.
Compression gloves Weaker than expected
The largest trial, A-GLOVES, tested real compression gloves against a placebo glove in over a hundred people. After twelve weeks, both groups improved about the same. Interestingly, people in both groups still said the gloves helped — and pointed to the warmth, not the compression, as the reason. If you already love your gloves, keep wearing them. Just know you’re paying for comfort, not a proven mechanism.
The daily-living toolkit
Not everything that helps has been through a randomized trial, and that’s okay. The guidelines recommend something simpler, called joint protection: look at what’s actually hard for you, and get a tool that removes that specific barrier. Jar openers, built-up utensils, ergonomic pens, button hooks, key turners. One practical tip: look for the Arthritis Foundation’s “Ease of Use” seal — it means the product was tested by people with arthritis, not just popular on a shopping site.
