Kinesiology tape · Forearm
How to tape a forearm with pre-cut kinesiology tape, for forearm extensor strain, RSI from keyboard and mouse work, climber’s forearm pump, De Quervain’s tenosynovitis and the forearm side of tennis and golfer’s elbow. Also sold as KT tape, K tape, kinesio tape and sports tape.
To tape a forearm you need one long strip and one short one. Straighten the arm and bend the wrist down so the back of the forearm is on stretch. Anchor the long strip on the back of the hand just past the wrist with no stretch and run it up the back of the forearm to the outside of the elbow at 25% stretch. Cut a second strip in half and lay the 12cm piece across the tender spot at 50 to 75% stretch. Wear it 5 to 7 days.
Yes, in ordinary use. Kinesiology tape is the product category. KT Tape is one American brand of it, and the name stuck as a generic term in the UK, alongside K tape, kinesio tape, sports tape and muscle tape. They all describe the same thing: elastic tape worn on the skin to support muscles and joints without restricting movement.
The forearm carries the load of every grip you make, which makes it the most overused area in modern desk and climbing life. Pain here shows up in three groups: racket-sport players, desk workers with RSI or De Quervain’s, and climbers with pump and pulley strains. This page covers six of the most common forearm conditions, with the taping pattern for each.
Position: Straighten the arm and bend the wrist down (fingers towards the floor) so the back of the forearm is on stretch. For golfer’s elbow, bend the wrist up instead and tape the inside.

Every strip is a pre-cut 5cm × 25cm I-strip from the dispenser box, 20 to a roll. Need a Y-strip? Cut one in 10 seconds. Anchors always go on with no stretch, and the tape comes off best in the shower, rolled back slowly along the hair. Basics for any area: how to apply kinesiology tape.



Three rolls if you are treating tennis elbow, one if it is an occasional niggle. A forearm application takes one and a half pre-cut strips, so a roll of 20 covers about thirteen applications. Tennis elbow takes three months as a rule and most people re-tape twice a week rather than wearing one application out, so three rolls for £14.97 delivered free is the realistic buy. A single roll is £4.99.

Pain on the outer point of the elbow that radiates down the back of the forearm, worse on gripping, lifting a kettle, or backhand strokes. The common extensor tendon at the lateral epicondyle is irritated. Despite the name, only 5% of cases come from actual tennis; most are from work-related gripping, mouse use and DIY.
Tape pattern: Strip 1 anchors at the back of the wrist, runs up the back of the forearm to just past the elbow at 25% stretch (apply with wrist bent forward to lengthen the extensors). Strip 2 horizontal decompression strip across the painful lateral epicondyle at 75% stretch.
Full Tennis Elbow Guide →Pain on the inner point of the elbow that radiates down the front of the forearm, worse on gripping, lifting palm-up, or pulling movements. Mirror image of tennis elbow but on the flexor tendons. Common in golfers (the trail-arm), throwers, climbers and weightlifters doing lots of chin-ups or deadlifts.
Tape pattern: Strip 1 anchors at the front of the wrist, runs up the front of the forearm to just past the inner elbow at 25% stretch (apply with wrist bent back to lengthen the flexors). Strip 2 horizontal decompression strip across the painful medial epicondyle at 75% stretch.
Full Golfer’s Elbow Guide →Sharp pain on the thumb-side of the wrist that worsens on lifting, gripping or moving the thumb sideways. Classic positive Finkelstein’s test: tuck thumb into fist, bend wrist toward little finger, sharp pain at the thumb tendons. Common in new parents (lifting babies), texters, gamers, and racket-sport players.
Tape pattern: Y-strip with base on the back of the thumb, two tails running over the thumb tendons and across the back of the wrist toward the elbow at 50% stretch (apply with wrist bent toward little finger). Lifts skin off the irritated tendon sheath.
Diffuse aching across the back of the forearm after a long session of typing, mousing, painting or racket sport. The wrist extensors (extensor digitorum, ECRB, ECRL) become tight, sore and weak from sustained gripping. Often a precursor to tennis elbow if not addressed.
Tape pattern: Long I-strip from the back of the wrist up the centre of the back of the forearm to just past the elbow at 25% stretch. A second strip parallel can be added either side for full coverage in heavy-use cases.
Generalised aching, tightness, burning or tingling through the forearm, wrist or hand from sustained keyboard, mouse, phone or controller use. Often combines extensor irritation, nerve sensitivity, and tight forearm muscles. Worse at the end of a working day and on weekends with long gaming sessions.
Tape pattern: Combination: a long I-strip up the back of the forearm at 25% stretch for extensor off-load, plus a horizontal wrist strip at 50% stretch. The bigger fix is workstation setup and micro-breaks.
Carpal Tunnel Guide →Burning, swollen, painful forearm pump that builds during a climbing session and lingers into the next day. The deep finger flexors (FDP and FDS) and brachioradialis get worked relentlessly on every grip. Chronic loading can lead to pulley strains, medial epicondyle pain and flexor tendinopathy.
Tape pattern: Long I-strip up the front of the forearm from wrist to inner elbow at 25% stretch for flexor off-load. Add a horizontal compression strip just below the elbow at 75% stretch to support the common flexor origin. Combine with hangboard load management.

Shop 10 Plain ColoursShop Talisman DesignsIt helps the symptom while the desk setup fixes the cause. RSI in the forearm is the extensor muscles being held at low tension for hours at a time, and a strip running up the back of the forearm at 25% stretch gives them something to work against and reminds you when the wrist has dropped. The tape is thin enough to wear under a watch strap and a shirt cuff all day. It will not outrun a bad workstation: a vertical mouse, a monitor at eye level and a break every half hour do the actual work.
Along the flexors, on the palm side, not across them. Climber’s pump is the flexor compartment swelling under repeated hard grip, so turn the palm up, bend the wrist back, anchor a strip at the base of the palm and run it up the middle of the inner forearm at 25% stretch. Keep the tension light: the aim is to decompress the compartment rather than to strap it, and anything tight makes pump worse. For a finger pulley injury, tape the finger itself with the H-tape method instead.
The forearm is a dense bundle of muscles and tendons that all converge at the wrist and elbow, which is why overuse so often lands at those two ends. Three mechanisms make tape effective. First, off-load along the muscle: a longitudinal strip with stretch shares pulling force away from the irritated tendon attachment at the elbow. Second, decompression at the tender point: a horizontal strip with higher stretch lifts skin off the inflamed epicondyle or tendon sheath. Third, proprioceptive cueing: the tape reminds you to grip less tightly and to move from the shoulder rather than the wrist, both critical for tennis elbow and RSI.
For De Quervain’s specifically, the decompression Y over the thumb tendons can be transformative within a few days. For chronic tennis or golfer’s elbow, tape is an adjunct to the heavy slow resistance work that actually rebuilds the tendon, not a standalone fix.
Yes. The tape is water resistant, so a shower will not lift it. Pat it dry with a towel rather than rubbing. It is not waterproof, so repeated swimming will shorten the wear. Hand washing catches the wrist end of the strip, so start it above the wrist crease where you can.
5 to 7 days, through showers, sweat and typing. Hairy forearms are the usual reason a strip lifts early, so trim the tape line with scissors first. Rub the tape for 20 seconds after applying to warm the adhesive, round the corners of every strip, and keep the anchors off the wrist crease, which folds every time you type.
Yes. Tape under the counterforce strap works well. Tape handles the soft-tissue off-load; the strap takes load away from the painful tendon attachment.
Yes. The tape is thin enough to fit under a watch or sleeve and doesn’t restrict wrist movement.
With tape, eccentric loading and load management, most cases settle in 3–6 months. Without these, can drag on for 1–2 years. The condition is self-limiting eventually, but rehab dramatically shortens it.
No, they are different conditions. De Quervain’s is tendon irritation on the thumb side of the wrist (worse on thumb movement and gripping). Carpal tunnel is median nerve compression in the wrist (numbness in thumb, index, middle finger, especially at night).
Yes, no issue. Many desk workers and racket-sport players need bilateral taping. Use two strips per arm for full extensor/flexor coverage.
