Repetitive Strain Injury (RSI)
Repetitive strain injury is pain that builds up in a hand, wrist, forearm, elbow or shoulder from doing the same movement many thousands of times. At Modern Physio we focus on understanding the root-cause of your problem & personalizing your treatment for lasting results.
Understanding Repetitive Strain Injury (RSI)
Repetitive strain injury is pain that builds up in a hand, wrist, forearm, elbow or shoulder from doing the same movement many thousands of times. It is the classic desk and keyboard problem, and in Jaipur it is just as often a tailor, a hairdresser, a supermarket cashier or someone spending hours a day on a phone. The pain usually starts as an ache that goes away overnight, then starts lasting into the next morning, then starts appearing during the task rather than after it. That progression is the important part, because RSI caught early responds much better than RSI ignored for a year. Rest alone is not the treatment. Prolonged rest weakens the tissue, and the pain comes back the moment you go back to work.
Common Symptoms
- Aching, throbbing or burning in the hand, wrist, forearm, elbow or shoulder
- Pain that begins after the activity and, over time, begins during it
- Stiffness or a feeling of weakness in the affected arm
- Tingling or numbness, particularly at night
- Reduced grip strength, or dropping things
- Pain that no longer settles fully overnight
- Cramping or a sense that the muscles are working much harder than the task requires
How Common Is It?
Repetitive strain problems are among the most common work-related musculoskeletal complaints, and among the most commonly worked through until they become persistent. People rarely present early, because in the early stage the pain reliably disappears overnight.
Causes & Risk Factors
- Repeating the same movement for long periods without variation, at work or at home
- Typing, mouse use and phone use held in one fixed position for hours
- A workstation set at the wrong height, so the wrist or shoulder is loaded continuously
- Repetitive manual work: tailoring, hairdressing, kitchen work, packing, checkout scanning
- Power tool use and sustained vibration
- A sudden increase in volume of the activity, rather than the activity itself
- Working through early pain rather than changing anything about how the task is done
Our Diagnosis Process
- A detailed history of the task, including how many hours, how often, and what changed before the pain started
- Locating which structure is actually painful, since RSI is a description rather than a diagnosis
- Testing grip, movement and strength, and reproducing the pain with the movement that causes it
- Screening for specific conditions that need naming separately, including carpal tunnel syndrome, tennis and golfer's elbow, De Quervain's and trigger finger
- Checking the neck, because arm pain and tingling frequently come from the cervical spine rather than from the arm
- Looking at the actual workstation or work posture, using photographs where you cannot bring the setup in
- Referral for medical assessment where there is progressive weakness, wasting, or persistent night numbness
Our Treatment Approach
- Modifying the task first, because treatment cannot outpace an unchanged daily load
- Graded loading of the affected tissue, which is what restores capacity, rather than rest, which reduces it
- Manual therapy and soft-tissue work to reduce pain enough for loading to begin
- Nerve mobility work where tingling or numbness is part of the picture
- Strengthening the shoulder blade and neck, because forearm symptoms are frequently driven from further up the chain
- Workstation and technique changes: height, keyboard and mouse position, tool grip, break structure
- Dry needling or electrophysical modalities as adjuncts where assessment indicates them, never as the whole plan
Recovery & Prevention Tips
- Vary the movement before you rest it. Micro-breaks every 30 to 45 minutes beat one long break
- Do not stop using the arm entirely: extended rest weakens the tissue and the pain returns on restarting
- Fix the workstation once, properly, rather than adjusting it slightly every few weeks
- Increase any activity gradually after a break rather than returning at full volume
- Pain that lasts more than a few days after the task, or that wakes you at night, needs assessment
- Progressive weakness, muscle wasting or constant numbness needs medical assessment, not physiotherapy alone
Evidence & Sources
RSI is caused by repeated use of a body part, staying active is advised over prolonged rest, and physiotherapy is a recognised treatment where symptoms persist.
NHS — Repetitive strain injury (RSI)Frequently Asked Questions
Is RSI a real diagnosis?
RSI is an umbrella description rather than a single diagnosis, which is why part of the assessment is finding out what is actually painful. Some cases turn out to be carpal tunnel syndrome, tennis elbow, De Quervain's or a neck-driven problem, each of which has its own treatment. Naming it correctly changes what is done about it.
Should I rest it completely?
No. Prolonged complete rest reduces the capacity of the tissue, so the pain returns as soon as you go back to the task. The plan is to reduce the aggravating load, keep the arm working within comfort, and rebuild capacity gradually.
Will a wrist splint help?
Sometimes, particularly at night for symptoms with a nerve component, and it can help settle an acute flare. It is a short-term aid rather than a treatment, because a splint that is worn continuously reduces the movement and strength you are trying to restore.
How long does it take to settle?
It depends mostly on how long the symptoms have been present and on whether the daily load can actually be changed. Weeks for a recent problem where the task can be modified; longer where it has been present for months and the work cannot change much. Anyone giving you a fixed number of sessions for this is guessing.
Do I need a scan?
Usually not. RSI is diagnosed from the history and the examination, and most scans of a painful forearm show nothing that changes the plan. Imaging is worth considering where there is progressive weakness, wasting, or a suspicion of something other than a repetitive-load problem. Dr. Surabhi Bansal is a physiotherapist, not a physician: the clinic does not prescribe medication and has no imaging on site. Where medication review, investigation or a specialist opinion is the right next step, you will be told so and referred.
