Repetitive strain injury (RSI) is pain in the hand, wrist, forearm or elbow that builds up from repeated or sustained use: typing, mouse work, phone scrolling, lifting, or gripping tools. RSI is an umbrella term. Underneath it sits a specific problem, such as De Quervain’s tenosynovitis, carpal tunnel syndrome or tennis elbow, or a more general overload of the forearm muscles. Repetitive strain injury treatment works once a clinician names that problem, changes the load on it, and builds your capacity back with graded strengthening.
Complete rest seldom solves RSI. Early-stage RSI recovers faster than pain that has lingered for months, so an ache that returns each working day deserves attention before it starts disturbing your sleep.
At Phoenix Rehab Group, our hand therapists find the structure behind your symptoms, review your work set-up and tasks, and give you a plan you can follow at your desk, workbench or kitchen. You do not need a doctor’s referral. If hand or arm pain keeps coming back with work, schedule a hand therapy assessment.
RSI at a glance
| What it is | An umbrella term for pain from repeated or sustained use of the hand, wrist, forearm or elbow |
| What it is | Work-related upper limb disorder, overuse injury, cumulative trauma disorder |
| Common in | Desk workers, students, gamers, musicians, F&B and cleaning workers, hairdressers, new parents |
| Main symptoms | Aching, burning or tightness; weakness; tingling if a nerve is involved |
| First step | Name the specific condition under the RSI label |
| First-line care | Load and set-up changes, graded strengthening, targeted treatment for the specific condition |
| First-line care | Early stage 2 to 6 weeks; established RSI 3 to 6 months or longer |
| See a doctor if | Numbness or weakness is getting worse, both hands and feet are affected, or the arm is red, hot and swollen |
What is a repetitive strain injury?
RSI describes how the pain started.
It does not name the injured tissue. Clinicians use it for a group of conditions that share a cause: a hand, wrist or forearm doing the same work, over and over, with too little recovery time. The first job in treatment is to work out which of these you have.
| Condition | Where it hurts | Typical trigger |
| De Quervain’s tenosynovitis | Thumb side of the wrist | Lifting, pinching and thumb-heavy phone use |
| Carpal tunnel syndrome | Tingling in the thumb, index and middle fingers | Forceful gripping, vibrating tools, a bent wrist |
| Tennis elbow | Outer elbow and forearm | Gripping with the wrist bent back, mouse work, lifting palm-down |
| Golfer’s elbow | Inner elbow | Gripping with the wrist bent forward |
| Trigger finger | A finger or thumb that catches or locks | Repeated hard gripping |
| Intersection syndrome | Back of the forearm above the wrist, with creaking | Rowing, gym work and repeated wrist movement |
| Wrist tendonitis | Tendons around the wrist | Repeated wrist bending under load |
| Thumb joint pain | Base of the thumb | Pinch and twist tasks |
| Cubital tunnel syndrome | Tingling in the ring and little fingers | Long periods with the elbow bent, such as holding a phone |
| Non-specific forearm pain | Diffuse aching in the forearm | Long hours of typing and mouse work |
If no single structure explains your pain, clinicians call it non-specific arm pain. The pain is real, and it responds to the same plan of load changes, set-up changes and strengthening.
RSI symptoms
The five most common RSI symptoms are:
- Aching, burning or throbbing pain in the hand, wrist, forearm or elbow.
- Tightness or stiffness, often worse in the morning or after a long appointment.
- Weakness: a reduced grip, dropping things, or tiring early during a task.
- Tingling or numbness, if a nerve is involved.
- Cramp or fatigue in the forearm muscles during the task.
Symptoms start during the task and ease with rest. Over time they linger longer, arrive sooner and begin to affect sleep.
The three stages of RSI
Clinicians often describe RSI in three stages. The stage tells you how soon to act.
| Stage | What you notice | Outlook |
| Stage 1 | Ache during the task that settles overnight; no loss of performance | Settles in 2 to 6 weeks with changes |
| Stage 2 | Pain lingers after the task, returns sooner and may disturb sleep; some loss of performance | Recovers over 6 to 12 weeks |
| Stage 3 | Pain at rest and with light tasks, broken sleep, weakness | Recovery takes 3 to 6 months or longer, with a structured program |
What causes Repetitive Strain Injuries in the Upper Limb RSI?
RSI builds when the load on a tissue outruns its ability to recover. Several factors add to the load:
- Repetition. The same movement thousands of times a day, such as mouse clicks or scanning items.
- Force. A tight grip on a mouse, pen, knife, wok or tool.
- Awkward or static posture. A wrist bent back on a laptop edge, shoulders hunched, or a hand holding one position for long periods.
- Too few breaks. Long appointments without a change of task.
- Sudden jumps in workload. A deadline, a new job, a new instrument piece or a gaming marathon.
- Vibration. Power tools and floor polishers.
- Stress and poor sleep. Both make nerves more sensitive to pain and slow recovery.
In Singapore, we see RSI in:
- CBD desk workers, and people working from home at a dining table with a laptop.
- Students during exam periods, with long hours of writing and laptop work.
- Gamers and esports players.
- Musicians, before exams and performances.
- F&B and hawker workers, from woks, ladles, knives and trays.
- Cleaners, from mops, spray bottles and wringing cloths.
- Hairdressers, from scissors and hairdryers.
- Factory and warehouse workers, from scanning, packing and assembly.
- New parents, from lifting and feeding.
- Commuters who scroll a phone with one thumb for the whole MRT ride.
How is repetitive strain injury in the hand, wrist & upper limb diagnosed?
A hand therapist or doctor diagnoses the condition behind RSI from your history and an examination. Scans are seldom needed.
- The task history. Your clinician asks about your hours, tools, set-up, recent changes in workload, sport, hobbies, sleep and stress.
- Locating the structure. Your clinician presses along the tendons, muscles and nerves to find the source of the pain.
- Tendon tests. For example, the Finkelstein test for De Quervain’s, or resisted wrist extension for tennis elbow.
- Nerve tests. Tinel’s and Phalen’s tests at the wrist, and an elbow bend test for the ulnar nerve.
- A neck screen. Neck problems can refer pain and tingling into the arm.
- Grip strength, measured and compared with the other hand.
- A task review. Photos or a short video of your workstation or work task show the positions that load the sore tissue.
A doctor arranges an ultrasound scan for tendon problems or nerve conduction studies for nerve symptoms when the picture is unclear or not improving.
Repetitive strain injury treatment in Singapore: your options
| Option | Who provides it | What the evidence shows | When it fits |
| Load management | Hand therapist | Core of treatment: reduce and spread the load while staying active | From day one |
| Workstation and task changes | Hand therapist or occupational therapist | Eases symptoms; single gadgets such as ergonomic keyboards show mixed results | From day one |
| Graded strengthening | Hand therapist | Exercise and workplace changes have the most research support | Once irritability settles |
| Splint or brace | Hand therapist | Helps specific conditions for short periods | For example, a night splint for carpal tunnel or a thumb splint for De Quervain’s |
| Manual therapy and massage | Hand therapist | Short-term relief; works as an add-on | Alongside exercise |
| Medication or injection | Doctor | Short-term relief for specific conditions | Selected cases |
| Surgery | Hand surgeon | Treats specific conditions such as carpal tunnel or trigger finger | A small minority |
Change the load, keep moving. Weeks of complete rest weaken the tissues, and pain returns once work resumes. The aim is to cut the peaks of load and keep the rest of your activity going. Spread long tasks through the day, alternate hands, switch between tasks, use two hands for heavy lifts, and choose lighter or thicker-handled tools.
Fix the set-up. Small changes to your desk, chair, laptop and phone habits reduce the load on sore tissues for eight or more hours a day. The checklist further down this page covers the essentials.
Build capacity with strength work. Stronger forearm, hand and shoulder blade muscles tolerate more typing, gripping and lifting. Research on work-related arm pain supports exercise and workplace changes more than any single gadget.
Use braces for specific conditions. A night splint helps carpal tunnel syndrome, and a thumb splint helps De Quervain’s. A wrist brace worn all day while typing can shift strain to the elbow and weaken the forearm muscles, so use braces for a set purpose and a set period.
Protect sleep during a flare. Poor sleep and high stress make nerves more sensitive to pain. A wind-down routine, a night splint where it fits, and a pain plan agreed with your doctor all help.
Medication and injections. A doctor may prescribe pain relief or inject a specific tendon or nerve tunnel. Hand therapists do not prescribe medication or give injections; we coordinate your plan with your doctor.
Hand therapy for RSI at Phoenix Rehab Group
Our hand therapy team is led by Nigel Chua, Principal Hand Occupational Therapist & Director, who has treated hand and wrist conditions since 2005. Our hand therapists are AHPC-registered occupational therapists and physiotherapists with post-graduate training in hand therapy.
At your first appointment, you can expect:
- A detailed task history. Hours, tools, phone use, sport, hobbies, sleep and stress.
- An examination that names the problem. We confirm which condition sits under your RSI, or whether it is non-specific forearm pain.
- A workstation or task review. Bring photos or a short video of your desk or work set-up, and we suggest specific changes.
- A load plan. The tasks to reduce, spread or change, and a way to keep working.
- A graded strength program, set at a level your tissues tolerate now.
- A splint only if a specific condition needs one.
At follow-up appointments, we progress your strength work, adjust your set-up and plan your return to full hours. We can provide a clinical report or a note on modified duties for your employer. Most people with established RSI need 4 to 8 appointments over 6 to 12 weeks, and early cases need fewer.
Contact us for an RSI assessment. WhatsApp us or schedule an assessment online.
Office and laptop set-up for Upper Limb & Hand Repetitive Strain Injuries
Use this checklist at the office and at home.
- Screen: top of the screen at eye level, about an arm’s length away.
- Laptop: on a riser with a separate keyboard and mouse, including when you work from the dining table.
- Keyboard: at elbow height, with your wrists straight and level while you type.
- Mouse: close to the keyboard and your body. Try keyboard shortcuts, switch hands for part of the day, or trial a vertical mouse.
- Forearms: supported by the desk or the arms of the chair, with shoulders relaxed.
- Chair and feet: hips a little higher than knees, feet flat on the floor or a footrest.
- Breaks: a 30 to 60 second movement break every 30 to 45 minutes, and a change of task each hour.
- Phone: two hands for long messages, voice typing, and a stand for video calls. Limit long one-thumb scrolling.
- Sofa and bed: keep laptop work there to short appointments.
For numbness in the thumb and fingers, see the desk tips on our carpal tunnel syndrome page. Our occupational therapists can review more complex workplace set-ups.
Hand & Upper Limb Repetitive Strain Injuries in Musicians and Gamers
Gamers and esports players. Long appointments, a tight claw grip on the mouse and fast keyboard work load the forearm tendons. Build in breaks between matches, warm up the hands before ranked play, check that the mouse fits your hand, and keep the wrist supported and straight on the keyboard.
Musicians. Practice hours often jump before exams, auditions and concerts. Increase practice in steps, split long appointments into blocks with breaks, check the set-up of your instrument and stand, and ask your teacher to review technique on the passages that hurt.
RSI recovery time
Recovery depends on the stage, the specific condition and how much you can change the load. Your therapist or doctor may give you different targets; use theirs.
| Situation | What happens | Typical timeframe |
| Stage 1 RSI | Symptoms settle with load and set-up changes | 2 to 6 weeks |
| Stage 2 RSI | Structured load changes and strength work | 6 to 12 weeks |
| Stage 3 RSI | Structured load changes and strength work | 3 to 6 months or longer |
| A specific condition under the RSI label | Structured load changes and strength work | See the condition page |
You are on track if you can work longer before symptoms start, the ache settles faster after work, and your sleep returns to normal. Contact your therapist if symptoms spread, numbness appears, or pain rises despite the changes.
RSI exercises
Start these once your clinician has checked for nerve involvement and named the condition. Exercise selection and dosages below need clinician sign-off.
Stage 1: movement breaks (from day one)
- Tendon glides. Move through a straight hand, hook fist, full fist and flat fist. 5 rounds in each movement break.
- Wrist bends and forearm turns. Bend the wrist up and down, then turn the palm up and down, within comfort. 10 of each, in each movement break.
- Shoulder rolls and chin tucks. 5 of each, in each movement break.
Stage 2: build strength (pain settling)
- Wrist holds. Press the back of the hand, then the palm, against your other hand without moving. Hold 5 to 10 seconds, 5 times each way, twice a day.
- Grip with therapy putty. 2 to 3 sets of 10.
- Wrist curls with a light weight. Palm up and palm down, lowering over 3 seconds. 3 sets of 12.
- Band rows. Pull a resistance band toward your ribs, squeezing the shoulder blades back. 3 sets of 12.
Stage 3: build endurance for your task
- Heavier forearm strength work, as your therapist progresses it.
- Task blocks. Build typing, playing or tool work in timed blocks with breaks, adding 5 to 10 minutes per block each week.
Stop or scale back if pain during an exercise goes above 3 out of 10, pain is higher the next morning, or tingling lingers after the exercise.
One habit to drop: hard, sustained stretching of sore forearm tendons. Stretching an irritated tendon under tension can flare it, so keep stretches within comfort.

RSI and your employer
- Tell your employer or HR early. Task rotation, adjusted hours and breaks do more before RSI reaches stage 3.
- Work injury reporting. If your RSI relates to your job, report it to your employer. Some work-related conditions fall under Singapore’s Work Injury Compensation Act
- Documentation. We can provide a clinical report or a modified-duties note to support changes at work.
When to see a doctor
Call 995 or go to A&E if:
- you have sudden weakness or numbness of the face, arm or leg, slurred speech or a drooping face (possible stroke)
Make an appointment with a doctor soon if:
- numbness or weakness in the hand is getting worse
- night pain keeps rising
- the arm is swollen, red and hot, or you have a fever
- both hands and both feet are numb or tingling
- neck pain spreads down the arm with tingling
- symptoms have not improved after 4 to 6 weeks of load and set-up changes
Frequently asked questions about repetitive strain injury
How long does a repetitive strain injury take to heal?
Early RSI, with an ache that settles overnight, often recovers in 2 to 6 weeks with load and set-up changes. RSI that lingers after work and disturbs sleep takes 6 to 12 weeks. Pain at rest and with light tasks can take 3 to 6 months or longer and needs a structured program. Recovery is faster once a clinician names the specific condition behind your symptoms and you start treating it.
What are the five symptoms of RSI?
The five most common RSI symptoms are aching, burning or throbbing pain; tightness or stiffness; weakness and reduced grip; tingling or numbness; and cramp or fatigue in the forearm muscles. They affect the hand, wrist, forearm or elbow, start during the task and ease with rest at first. Numbness or weakness that is getting worse needs a doctor’s review.
How do you cure repetitive strain injury?
No single treatment fits all cases, because RSI is an umbrella term. Treatment starts with naming the condition underneath, such as De Quervain’s, carpal tunnel syndrome or tennis elbow. Then you reduce and spread the load, fix your set-up, and rebuild strength in stages. Exercise and workplace changes have the most research support. Splints, injections and surgery help specific conditions, and complete rest seldom does.
What is a repetitive strain injury?
A repetitive strain injury is pain in the hand, wrist, forearm or elbow caused by repeated or sustained use, such as typing, mouse work, phone use or gripping tools. RSI is an umbrella term that covers specific conditions, including De Quervain’s tenosynovitis, carpal tunnel syndrome, tennis elbow and trigger finger, and non-specific forearm pain. Doctors also call it a work-related upper limb disorder.
Is RSI permanent?
Most people recover from RSI with the right changes and treatment. Recovery takes longer when symptoms have reached stage 3, with pain at rest and broken sleep, but people still improve with a structured program. Nerve compression left for a long time, such as severe carpal tunnel syndrome, can leave lasting numbness, so get numbness or weakness checked early.
Should I wear a wrist brace for RSI?
Wear a brace only for a specific condition and a set period, as your therapist advises. A night splint helps carpal tunnel syndrome, and a thumb splint helps De Quervain’s. A wrist brace worn all day while typing can shift strain to the elbow and weaken the forearm muscles. Load changes, set-up changes and strength work do more for most people with RSI.
Can RSI cause numbness in the fingers?
Yes. Numbness or tingling means a nerve is involved. Tingling in the thumb, index and middle fingers points to carpal tunnel syndrome, and tingling in the ring and little fingers points to cubital tunnel syndrome at the elbow. Numbness that is getting worse, or weakness in the hand, needs a doctor’s review, and a hand therapist can help find the cause.
Can I claim RSI as a work injury in Singapore?
Some work-related conditions fall under Singapore’s Work Injury Compensation Act. If your RSI relates to your job, report it to your employer and keep records of your symptoms, tasks and treatment. We can provide a clinical report to support your case. For advice on a claim, contact the Ministry of Manpower or your employer’s insurer.
Do I need a referral to see a hand therapist for RSI in Singapore?
No. You can see a hand therapist at Phoenix Rehab Group without a doctor’s referral. If your symptoms point to a nerve problem or need an injection or scan, we refer you to a doctor and share our findings. Some insurers ask for a doctor’s referral before they reimburse therapy, so check your policy first.
Contact us for an RSI assessment
If hand, wrist or arm pain keeps returning with work, a hand therapist can name the cause and build a plan that fits your job.
- WhatsApp: Message us. Your message opens with “Hi, I’d like to schedule a hand therapy assessment for repetitive strain injury.”
- Online: schedule an assessment
- Clinics: Orchard, Serangoon, Tampines, Tanjong Pagar at International Plaza and Jurong East at Vision Exchange, opening 20 October 2026.
- Referral: not required. Some insurers need one for claims, so check your policy.
- Insurance: we provide itemised invoices, and a clinical report if your insurer asks for one.
If the pain builds over a day at the desk, office syndrome covers the neck, back and wrist problems behind it. If you play an instrument, musician injuries covers hand, wrist and arm pain from playing.
Where the symptoms follow the ulnar nerve and are worse with the elbow bent for long periods, the Cubital Tunnel Recovery Program sets out the four stages and the criteria to move up.
Where are you with this right now?
1. It is settling on its own
Many hand problems settle with a well fitted splint, changes to what provokes them, and tendon gliding. A tender scar and weak grip for a few weeks after surgery are usual. If it is easing week on week, and grip is improving month on month, it is behaving as expected. You do not need us for this, and we would rather say so.
2. It has stopped improving
You hand the jar to someone else. You button the shirt one-handed. You have stopped using that hand for anything that matters and barely noticed when it started.
The hand is the part of the body where stiffness sets in fastest, because a hand that hurts gets used less within days rather than weeks. That is the gap worth measuring, and it is not measured by how you feel on the day.
The Stalled Recovery Review is three appointments over three weeks with the same therapist, because what a joint does under load cannot be read in one visit. The first finds what is limiting it. The next two measure how it responds. $690, nett, no GST, which is three appointments at $230.
3. You have had surgery, or you have a date
Recovery after an operation has a shape, and knowing which stage you are in tells you whether you are on it. See the recovery programs, or hand therapy after surgery if you are not sure which applies to you.
All of it runs on the same four stages. The Phoenix Recovery Protocol explains what each stage works on and what you have to meet to move up. No referral needed to start.
Next step
Find out which stage you are in
Pain is the first thing to leave. Movement and strength are the last things trained back, and most people stop before that part is done. One Assessment and Treatment is a single 45-minute appointment at $230, nett, no GST. Your therapist finds what is actually limiting you, treats it in the same appointment, and you leave with your current stage and a written plan.
Prefer to phone? Each of our five clinics has its own number on the clinics page. No referral needed to book.
