If you wake up shaking out a numb hand, or tingling in your thumb and first two fingers creeps in by mid-afternoon, your keyboard and mouse deserve a hard look. Not because they're broken, but because they're flat: a flat keyboard bends your wrists out and back, and a flat mouse holds your forearm palm-down for hours.
The shape of a device isn't magic, and the research is more mixed than the marketing. So before the picks, here's what the studies show, where the evidence is strong and where it's thin.
I narrowed these from the 53 keyboards and 49 mice I've scored to the split, tented and vertical designs the evidence supports: five keyboards, five mice.
What the research says about carpal tunnel, keyboards and mice
Carpal tunnel syndrome is pressure on the median nerve where it runs through a narrow channel at the wrist, and that pressure rises when the wrist bends away from straight. In a classic study, people with carpal tunnel syndrome averaged 32 mmHg with the wrist straight, against 2.5 in people without it, and 110 with the wrist bent back.1 Even in healthy volunteers, about 33 degrees of wrist extension, or about 15 degrees of sideways bend toward the little finger, pushed carpal tunnel pressure over a common risk threshold in a quarter of them.2
32 vs 2.5mmHg of carpal tunnel pressure with the wrist straight, with and without carpal tunnel syndrome.1 110 mmHgwith the wrist bent back, in the same patients.1 Keyboards: the stronger case
A split keyboard fixes the sideways bend. In a study of 90 experienced office workers, split keyboards set up correctly cut average ulnar deviation from about 12 degrees to within 5 of neutral.3 A meta-analysis of six studies found adjustable tented keyboards had a large effect on forearm rotation and the sideways bend, and fixed splits on the sideways bend, but no design fixed all three wrist positions.4 Tenting doesn't stop the wrist bending back;3,4 the slope does, and keyboards flat to slightly tilted away from you gave the least wrist extension.5 Whether that eases symptoms is less certain: in a six-month trial of 80 computer users with arm and hand disorders, two alternative keyboards showed an improving trend in pain against a placebo keyboard, without consistent change in clinical findings.6
Mice: helpful, but not the way the box says
A vertical mouse turns your forearm toward a handshake: in a controlled comparison, it cut forearm rotation from 42 to 28 degrees and lowered wrist extensor effort,7 and in a field study, office workers who switched to a mouse that held the forearm closer to neutral reported less neck, shoulder, forearm, wrist and hand pain.8 But in 21 people with carpal tunnel syndrome, neither a vertical mouse nor ergonomic mouse pads lowered carpal tunnel pressure: the vertical mouse cut the sideways bend but bent the wrist back the most, which the authors suggest may have cancelled the gain.9 Dragging matters too: in healthy volunteers, pressure while dragging ran about 12 mmHg higher than with the hand resting on the mouse.10 And a Cochrane review found too little high-quality evidence to call any ergonomic device a treatment for carpal tunnel syndrome.11
What this means for you
A vertical mouse is a real upgrade for your forearm, as long as you keep your wrist from bending back, and the shape isn't a treatment. That's why the adjustable 
Unimouse tops the mice here: you can set the angle where your wrist stays level.
The keyboards
Best keyboard
Cloud Nine C989M
DEAS 7.7 out of 10
Two halves that separate up to 6 inches; a built-in 7-degree tent; full size with a number pad; Kailh Box mechanical switches; molded palm rests.
If the outer edge of your hand goes numb by mid-afternoon, start here. Pull the halves apart until your wrists stop bending out, and the built-in tent takes a little of the roll out of your forearms. Keep the back flat, and rest the heels of your hands on the palm rests only between bursts.
Good: halves that separate up to 6 inches; a gentle built-in tent; a number pad; palm rests. Less good: the tent is fixed at 7 degrees; a large footprint; a learning period for the split.

Kinesis Advantage360
DEAS 7.6 out of 10
Contoured key wells in two separate halves, 15.25 to 21.25 inches apart (wired); three tent settings; a wireless Pro version. 3-year warranty.
Contoured key wells bring the keys to your fingers, the halves separate to shoulder width, and three tent settings ease the forearm roll. For someone with diagnosed carpal tunnel syndrome who types all day, it's the design I reach for. Kinesis is winding down the older 
Advantage2, so this is the one to buy.
Good: contoured key wells; fully separate halves; three tent settings; a 3-year warranty. Less good: the lowest price score of the five; a real learning period.

Best plug-and-play split
Perixx PERIBOARD-835
DEAS 7.4 out of 10
One-piece split with a built-in palm rest; low-profile Kailh mechanical switches, brown and tactile; wired, 2.4 GHz or Bluetooth; legs tilt it to -4 or -7 degrees. 1-year warranty.
The fixed split puts your wrists close to straight out of the box, the legs tilt it away from you, and the palm rest is built in. It does one job well and asks almost nothing of you.
Good: negative tilt built in; quiet tactile mechanical switches; a built-in palm rest; tied for the best reliability score from user reviews here. Less good: the split is fixed, with no tent; a 1-year warranty.

Easiest keyboard to switch to
Logitech ERGO K860
DEAS 7.3 out of 10
Curved one-piece split; full size with a number pad; front legs tilt it to -4 or -7 degrees; pillowed palm rest; pairs with up to 3 devices. 1-year warranty.
The curve is gentle enough that your typing speed barely dips, and the legs tilt it away from you so your wrists don't bend back. If you've never used an ergonomic keyboard, start here.
Good: a familiar layout; negative tilt; a pillowed palm rest; tied for the best reliability score from user reviews here. Less good: one piece, so you can't widen the split; membrane keys; a 1-year warranty.

Best for broad shoulders or one-sided pain
Kinesis Freestyle2
DEAS 7.1 out of 10
Two fully separate halves on a 9-inch cable, or 20 inches as an option; lies flat; quiet, low-force membrane keys; tent and palm-support kits sold separately. 2-year warranty.
If your shoulders are broad, or one wrist hurts far more than the other, the halves come fully apart, so each hand can sit where its own forearm points. It lies flat out of the box, which keeps your wrists from tipping back; add the tent kit if your forearms roll palm-down.
Good: fully separate halves; lies flat; quiet, low-force keys; a 2-year warranty. Less good: the tent and palm supports cost extra; membrane keys; too few user reviews yet for a reliability score.

The mice
Best mouse
Contour Unimouse
DEAS 8.0 out of 10
Tilt adjusts from 35 to 70 degrees; adjustable thumb support; right- and left-handed versions; wireless.
The only mouse here that lets you set the angle yourself, from 35 to 70 degrees. For carpal tunnel that matters: in a study of people with carpal tunnel syndrome, a fixed vertical mouse bent the wrist back the most. Set this one as steep as you can while your wrist still lies level.
Good: an angle you set yourself; an adjustable thumb support; right and left versions; the top score of any mouse we've rated. Less good: Contour publishes no hand-size range; it takes a few days to find your angle.

Best value mouse
Logitech Lift
DEAS 7.7 out of 10
57-degree angle; for small to medium hands; right- and left-handed versions; one AA battery, rated for about 24 months.
The 57-degree angle takes your forearm out of full palm-down, and it's sized for smaller hands, so you aren't stretching for the buttons. Keep your wrist level on the desk rather than cocked up.
Good: sized for small to medium hands; the best reliability score of these five; right and left versions. Less good: a fixed angle; too small for large hands; a 1-year warranty in the US.

Logitech MX Vertical
DEAS 7.4 out of 10
57-degree angle; for medium to large hands; right-handed only.
The same 57-degree angle as the Lift in a bigger body, so a larger hand can rest on it without clawing or pinching to grip.
Good: a 57-degree angle; sized for bigger hands; a good reliability score from user reviews. Less good: right-handed only; too big for small hands; a 1-year warranty in the US.

DEAS 7.1 out of 10
Handshake grip; for medium to large hands; right- and left-handed versions, wired as linked; a small right-handed size for hands under about 7 inches. 2-year warranty.
Evoluent's long-running vertical mouse holds your hand in a handshake grip, in right- and left-handed versions. Move it from your elbow and shoulder rather than flicking the wrist.
Good: a handshake grip; right and left versions; a small size for smaller hands; a 2-year warranty. Less good: Evoluent publishes no angle; the left-handed version is wired only.

Best trackball
Logitech MX Ergo S
DEAS 7.0 out of 10
Thumb-operated trackball; the base tilts to 0 or 20 degrees; right-handed; for medium to large hands; quiet clicks; USB-C charging; Logi Bolt receiver.
When a vertical mouse doesn't suit you, or the dragging is what hurts, a trackball keeps your arm and wrist still while your thumb moves the ball. It won't change your forearm angle as much as a vertical mouse does, but the 20-degree tilt helps.
Good: your arm and wrist stay put; a 20-degree tilt option; quiet clicks; USB-C charging. Less good: your thumb does the work, so not for thumb pain; right-handed only; a 1-year warranty in the US.

How to set them up to protect the median nerve
- 1
Lower the keyboard. Elbows about level with it and by your sides, shoulders relaxed.12 If the desk pushes your shoulders up, it is too high.
- 2
Tilt it flat or slightly away from you. Fold the back feet away; flat to slightly negative gave the least wrist extension.5
- 3
Set the split, then the tent. Widen the halves until your wrists run straight out from your forearms, then add just enough tent that your palms face slightly inward.
- 4
Set a vertical mouse as steep as your wrist allows. Keep the wrist level on the desk, not cocked up.9
- 5
Keep the mouse beside the keyboard. Reaching out for it bends the wrist and loads the shoulder.13
- 6
Rest the heel of your palm, only in pauses. Not your wrist, and not while you type.14
The test
If you can draw a straight line from your forearm across the back of your hand, your equipment is doing its job.
Is it carpal tunnel? What your wrist is telling you
Tingling thumb, index and middle fingers
Feels like
Numbness or tingling in those three fingers, often worst at night or first thing in the morning: the median nerve pattern.
What helps
A straight wrist, with a split, palm-supported keyboard and a vertical mouse. See a clinician if night numbness continues.
Tingling along the little-finger side
Feels like
Tingling or aching along the little-finger edge, often from leaning the wrist on a hard edge.
What helps
A split to stop the sideways bend, and a soft palm rest so the wrist edge isn't pressing on a hard surface.
Soreness without numbness
Feels like
Tired, sore wrists and forearms, but no pins and needles.
What helps
Less force and fewer movements: light-touch keys and a trackball like the 
MX Ergo S.
Clinical note
Numbness that won't go away at night, a weak grip, or wasting at the base of the thumb are reasons to see a doctor, not to shop. The right equipment supports recovery; it doesn't replace a diagnosis.
Common questions
Which keyboard and mouse design is best for carpal tunnel?
For the keyboard: a split, so your wrists stop bending out, kept flat or tilted slightly away from you so they don't bend back, with a tent if your forearms roll. For the mouse: a vertical one you can keep level, ideally with an adjustable angle. Those are the features that move the wrist toward straight, where carpal tunnel pressure is lowest.1,2
Will a vertical mouse cure my carpal tunnel?
No, and be wary of anything that says so. In people with carpal tunnel syndrome, a vertical mouse didn't lower carpal tunnel pressure, partly because their wrists bent back more,9 and a Cochrane review found too little evidence to call any ergonomic device a treatment.11 A vertical mouse is worth having for your forearm and comfort; symptoms that persist need a clinician.
Split keyboard or vertical mouse: which first?
Start with the device you use most. If you type far more than you mouse, start with the keyboard: the posture evidence for splits is the stronger of the two.3,4 If symptoms flare when you mouse, start there. Most people end up fixing both.
Should my wrist rest on the pad while I type?
No. OSHA's guidance is that your hands should move freely above the rest while you type, and that when you do rest, the pad should meet the heel of your palm, not your wrist.14 Planting the wrist and typing from it bends it back.
How long until a new keyboard or mouse stops feeling awkward?
In my experience, one to three weeks; the bigger the change, like contoured key wells, the longer. In a learning-curve study, typists quickly regained the speed they lost on a split and a contoured keyboard.15 Give it a full week before you judge it.
What other keyboards and mice are worth a look?
Keyboards: the Kinesis Advantage2 (7.7) while it's still sold, the 
Kinesis mWave (7.7), the 
R-Go Split (7.4). Mice: the left-handed 
Logitech Lift (7.7) and 
R-Go HE (7.5), and the 
Logitech Trackman Marble (7.0), a trackball you roll with your fingers. Every one is in the keyboard and mouse rankings.
What is the DEAS score?
The Desk Ergonomics Assessment Score, Desk Doctor's product rating out of 10. Every product is scored on eleven dimensions in three layers: clinical performance, product quality and value. For keyboards and mice, the category-specific part is how well the shape keeps your wrist neutral: straight for a keyboard, closer to a handshake for a mouse. How we score.
