Repetitive strain injury (RSI) is an umbrella term for pain and dysfunction caused by repetitive movements, awkward postures or sustained static positions — most commonly affecting the arms, wrists, hands, neck and shoulders. It is extremely common, particularly in desk workers and manual workers, and responds well to physiotherapy, ergonomic adjustment and, for persistent cases, targeted manual therapy.
See therapies that may helpRSI covers a range of conditions including tendinopathy, tenosynovitis, carpal tunnel syndrome, tennis elbow (lateral epicondylalgia) and golfer's elbow (medial epicondylalgia). What these conditions share is a causative relationship with repetitive or sustained loading of muscles, tendons and nerves beyond their capacity to recover.
RSI is strongly associated with computer use, keyboard and mouse work, assembly line work, and any occupation or activity requiring repetitive fine motor movements or sustained awkward postures. It has become significantly more prevalent as desk-based work has increased.
Early-stage RSI typically involves symptoms only during the activity and resolves with rest. Later-stage RSI may cause persistent symptoms regardless of activity and can significantly affect daily life and work capacity.
RSI symptoms typically include:
RSI responds well to early intervention. The longer it is left untreated, the more entrenched the symptoms become.
Do not wait to seek help for RSI — early intervention produces significantly better outcomes than allowing symptoms to become established. A physiotherapist or sports therapist is usually the most appropriate first contact. If symptoms involve significant neurological features (numbness, weakness), GP assessment to rule out nerve compression is advisable.
Addressing ergonomics and working practices alongside treatment is essential — physical therapy alone will not prevent recurrence if the underlying causes are not modified.

Most RSI resolves well with appropriate treatment and activity modification, particularly when caught early. Longstanding, severe RSI may leave some residual symptoms, but significant improvement is achievable in the vast majority of cases. The key is not to leave it untreated.
In most cases yes, but with modifications. Complete rest is rarely recommended — graded activity and ergonomic adjustment are more effective than stopping altogether. A physiotherapist can help you identify safe working modifications and a graduated return-to-activity plan.
Carpal tunnel syndrome (CTS) is a specific form of nerve entrapment at the wrist, involving compression of the median nerve, causing pain, tingling and numbness in the thumb, index and middle fingers. RSI is a broader term covering multiple conditions. CTS can be a component of RSI but has specific diagnostic features and, in some cases, specific treatments including splinting or surgery.
Stretching can be helpful as part of a comprehensive RSI management plan, but is not sufficient on its own and can be counterproductive if done incorrectly or when tissues are acutely irritated. A physiotherapist can advise on appropriate stretching and strengthening exercises specific to your presentation.
This varies considerably depending on the specific condition, its severity and duration, and how comprehensively the contributing factors are addressed. Mild RSI caught early may resolve within weeks. More established RSI may take 3–6 months of consistent treatment and activity modification to resolve fully.
