Quick Summary
If repeated tasks at work or home are leaving your hands, wrists, forearms or elbows aching, tingling or weak, you may be experiencing repetitive strain injury (RSI). Research suggests that staying gently active and following a structured physiotherapy programme of hands-on treatment, targeted exercise and ergonomic advice helps many patients reduce their pain and return to their usual activities. Our HCPC-registered physiotherapists will assess your individual pattern of symptoms and design a plan around your work and your goals.
What Is RSI (Repetitive Strain Injury)?
Repetitive strain injury (RSI) is an umbrella term for pain affecting the muscles, tendons and nerves of the upper limb — the shoulders, elbows, forearms, wrists and hands — arising from repetitive movement, sustained postures and overuse. It is also known as work-related upper limb disorder, non-specific arm pain or occupational overuse syndrome.
Clinicians commonly divide RSI into two categories. Type 1 RSI describes cases where symptoms fit a recognised, specific diagnosis — for example tennis elbow, De Quervain's tenosynovitis or tenosynovitis — often with identifiable features such as swelling. Type 2 RSI, also called diffuse or non-specific arm pain, describes pain that does not fit a defined diagnosis and lacks objective measurable signs.
Work-related musculoskeletal disorders are one of the most common causes of work-related ill health in Great Britain. The Health and Safety Executive estimates that around 511,000 workers were affected in 2024/25, with upper limb and neck disorders accounting for approximately 41% of cases — a rise linked partly to prolonged screen-based and hybrid working. Research also suggests that in persistent upper-limb pain, the nervous system itself can become more sensitive, which is why treatment addresses more than the sore tissue alone (Plinsinga et al., Journal of Orthopaedic & Sports Physical Therapy, 2015).
Do You Experience These Symptoms?
✓ Pain, aching or tenderness in your hand, wrist, forearm, elbow or shoulder, which may feel like burning or throbbing
✓ Stiffness, especially after periods of repetitive activity
✓ Tingling, pins and needles or numbness in the affected area
✓ Weakness, clumsiness or reduced grip strength
✓ Cramp in the muscles of the forearm or hand
✓ Symptoms that at first appear only during the repetitive task, but over time become more constant
✓ Sometimes swelling in the affected area, which can persist for several months
These symptoms can be treated.
The sooner you begin, the better your chances of a smoother recovery.
What Causes RSI?
• Repetitive and prolonged movements
Carrying out the same actions repeatedly for long periods — typing, using a mouse, assembly-line work, hairdressing or playing an instrument — is the most common driver of RSI.
Without adequate rest breaks, the tissues have little chance to recover between bouts of loading.
• Sustained or awkward postures
Holding the neck, shoulders or wrists in a fixed or awkward position, such as at a poorly set-up workstation, sustains low-grade muscle load and strains soft tissues.
Poor posture when sitting or standing at work is a recognised contributor.
• Forceful exertions and vibration
Gripping forcefully, lifting or using hand-held power tools that vibrate increases the mechanical demand on tendons and nerves.
Regular use of vibrating equipment is a well-documented occupational risk factor.
• Cold environments and inadequate recovery
Working in cold conditions and having insufficient rest breaks both increase risk.
Cold muscles do not extend properly, and fatigue accumulates when recovery time is inadequate.
• Psychosocial and workplace factors
Time pressure, high job demands, low job control and stress are associated with the onset and persistence of work-related arm pain.
This reflects the biopsychosocial nature of the condition, which is why we look at the whole picture — not just the sore area.
How We Treat RSI at J&J Therapy
Hands-On Manual Therapy
Hands-on soft-tissue and joint mobilisation techniques to help reduce pain and restore comfortable movement in the wrist, forearm, elbow and shoulder — always combined with exercise, education and practical activity advice.
Shockwave Therapy*
Swiss Storz Medical MASTERPULS
may complement your manual therapy and exercise programme when your physiotherapist identifies a specific tendinopathy component — such as tennis elbow or De Quervain's tenosynovitis — during assessment. Evidence for diffuse RSI itself is limited, so shockwave is never a first-line treatment for this condition.
Non-invasive, evidence-based where indicated.
Targeted Exercise Programme
An individualised programme of progressive strengthening and graded loading for the forearm, wrist and shoulder, with nerve gliding exercises where appropriate — alongside ergonomic and workstation advice, activity pacing and self-management strategies so you can stay active while your symptoms settle.
When to Seek Urgent Medical Help
While most symptoms are not serious, urgent medical attention is required if you experience any of the following:
Sudden or progressive weakness, wasting or significant loss of function in your arm or hand
Spreading redness, heat and swelling with fever or feeling generally unwell (possible infection)
Arm pain with chest tightness, breathlessness or pain spreading to the jaw — call 999 (possible heart problem)
Numbness or tingling in both arms, or with problems walking, balancing, or controlling your bladder or bowel
FAQs About RSI
How long does RSI take to get better?
Recovery varies. Many repetitive strain injuries settle within three to six months with appropriate activity modification and treatment, but research shows a substantial proportion of people still have symptoms at six months — so early recognition, staying active and addressing work factors give you the best chance of a good outcome.
Should I rest my arm completely?
Generally no. Brief relative rest of a day or two can help settle a flare, but prolonged rest tends to make the area weaker and stiffer. The NHS advises against resting the affected area for more than a few days, and research suggests advice to remain active leads to better recovery at six months than advice to rest.
Will I need a scan or tests?
Usually not. RSI — particularly the diffuse form — is generally diagnosed from your history and examination. Our physiotherapists will assess your symptoms, your movement and your work tasks, and investigations are reserved for cases where a specific diagnosis or red flag is suspected.
Can shockwave therapy treat my RSI?
Not as a first-line treatment. Evidence for shockwave in diffuse RSI is limited. However, if your assessment indicates that a specific tendinopathy — such as tennis elbow or De Quervain's tenosynovitis — is contributing to your symptoms, shockwave may be considered as a complementary option when your physiotherapist judges it may help, alongside your manual therapy and exercise programme.
Is RSI treatment covered by my private health insurance?
J&J Therapy accepts Bupa and AXA insurance. We recommend checking the terms of your individual policy, and our team can help guide you through the process.
