RSI

What Is Repetitive
Strain Injury?

Repetitive Strain Injury (RSI) is an umbrella term for a group of musculoskeletal disorders caused by repetitive movement, sustained posture, forceful exertion, or prolonged activity. It is also referred to medically as Work-Related Upper Limb Disorder (WRULD) when it affects the upper body.

RSI is not a single diagnosis. It covers a range of specific conditions including carpal tunnel syndrome, tenosynovitis, tendonitis (also spelled tendinitis in some sources), De Quervain's syndrome, epicondylitis (tennis elbow and golfer's elbow), rotator cuff disorders, and diffuse non-specific pain in the hands, arms, shoulders, neck, or back.

RSI is one of the most common forms of occupational ill-health in the UK. HSE statistics report approximately 470,000 workers in Great Britain each year suffering from musculoskeletal disorders caused or made worse by their work. Office-based RSI (particularly from DSE use) is the most common category Arinite sees in practice, but manual handling roles, production work, and healthcare are also significantly affected.

SYMPTOMS

RSI Symptoms
and Stages

RSI typically develops in three stages. Identifying the condition early is critical because late-stage RSI can become chronic and irreversible.

1

Early Stage: Reversible

Symptoms include aching, fatigue, or discomfort during work that resolves with rest overnight or at weekends. The worker can usually continue normal activities. At this stage, modifying the workstation, adjusting work patterns, and introducing breaks usually resolves symptoms. Most early-stage RSI is completely reversible if acted on promptly.

2

Progressive Stage: Requires Treatment

Symptoms persist after rest, may be present through the night, and begin to interfere with non-work activities. Pain may be sharp, burning, or associated with tingling and numbness (particularly in carpal tunnel syndrome). Weakness and reduced grip strength may appear. At this stage, medical treatment and workplace intervention together are required. Recovery is usually achievable but takes longer.

3

Chronic Stage: Potentially Irreversible

Symptoms are continuous, severe, and disabling. The worker may be unable to perform normal work or normal daily activities. Structural changes to tendons, nerves, or joints may have occurred. Full recovery becomes uncertain; many chronic RSI sufferers have ongoing symptoms for the rest of their working life.

LEGAL FRAMEWORK

The Legal Framework
for RSI Prevention

RSI is not covered by a single piece of UK legislation. Employers' duties to prevent and manage RSI arise from the general health and safety framework:

1

Health and Safety at Work Act 1974, Section 2

General duty to ensure the health, safety, and welfare at work of all employees. RSI prevention falls within this general duty.

2

Management of Health and Safety at Work Regulations 1999

Require employers to assess the risks to employees from their work and implement appropriate controls. RSI risk must be identified and addressed in the general risk assessment.

3

Health and Safety (Display Screen Equipment) Regulations 1992 (the DSE Regulations)

Require specific assessment and control of risks from display screen equipment work, which is the single largest source of office-based RSI.

4

Manual Handling Operations Regulations 1992

Where RSI arises from manual handling, the manual handling regulations also apply.

5

Provision and Use of Work Equipment Regulations 1998 (PUWER)

Require equipment to be suitable for the purpose and safe for use, including ergonomic considerations.

6

RIDDOR 2013

Carpal tunnel syndrome, tendonitis, and cramp of the hand or forearm are reportable occupational diseases under RIDDOR when a doctor diagnoses the condition and it is linked to specific occupational exposure.

Employers who fail to assess and control RSI risks face both regulatory enforcement under HSE powers and civil claims from affected employees. Civil RSI claims can result in significant damages, particularly where employers ignored early symptoms.

RISK FACTORS

Workplace Causes and
Risk Factors

RSI arises from the combination of task, equipment, and individual factors. The most common workplace risk factors are:

1

Repetition

Performing the same movement many times per hour over extended periods. Typing, mouse use, data entry, assembly work, production line work, and scanning are common repetitive tasks.

2

Force

The amount of physical effort required. Heavy keyboard striking, gripping tools, squeezing triggers, or sustained pinch grips all contribute to RSI risk.

3

Awkward postures

Positions that place joints away from their neutral range. Bent wrists, elevated shoulders, head tilted forward, or legs crossed under a desk all increase strain.

4

Static postures

Holding any position for prolonged periods without movement, even if the position is itself acceptable. Extended sitting and standing are both risk factors.

5

Vibration

Hand-arm vibration syndrome from power tools is a distinct RSI category. Whole-body vibration (from vehicles) also contributes to back and neck symptoms.

6

Environmental factors

Cold working temperatures, poor lighting, glare, time pressure, and low job control all increase risk.

7

Individual factors

Age, previous injury, pregnancy, and non-work activities (for example, sports or hobbies involving similar repetitive motions) can all affect susceptibility. Employers cannot control these directly but must take them into account in risk assessment.

Most RSI is multifactorial. A single cause is rare; combinations of the factors above produce the condition.

EMPLOYER DUTIES

Employer Duties for
RSI Prevention

Under the combined framework above, employers must:

1

Assess the risk of RSI arising from work activities. The assessment should be specific to the tasks performed and the individuals performing them. A generic DSE assessment is often the starting point but is not a complete RSI assessment.

2

Implement controls to reduce identified risks. Controls should follow the hierarchy: eliminate the hazardous activity where possible (process redesign, mechanical assistance), substitute with lower-risk alternatives, engineer controls (ergonomic equipment, workstation adjustment), administrative controls (task rotation, breaks, training), and personal equipment only as a last resort.

3

Provide information, training, and instruction to employees about RSI risks, recognition of early symptoms, and the controls in place.

4

Monitor for symptoms and respond promptly to reports. Early intervention is the single most effective prevention measure. A culture where employees feel able to report discomfort without stigma is critical.

5

Refer employees to occupational health where symptoms develop. Occupational health assessment confirms the diagnosis, guides treatment, and informs workplace adjustments.

6

Make reasonable adjustments for affected employees under the Equality Act 2010 where RSI progresses to a disability.

7

Report notifiable RSI diagnoses to the HSE under RIDDOR (carpal tunnel syndrome, tendonitis, cramp of the hand or forearm where work-related).

8

Review arrangements when tasks, equipment, or individuals change.

PREVENTION

How to Prevent RSI
in the Workplace

Effective RSI prevention combines workstation design, work pattern management, and worker awareness.

1

Ergonomic Workstation Setup

For office workers, a properly configured workstation is the foundation. Chair height, desk height, screen position, keyboard position, mouse position, and lighting should all be optimised for the individual. A one-size-fits-all setup does not prevent RSI. Arinite's DSE assessment service covers this in detail.

2

Regular Breaks and Microbreaks

The HSE recommends short frequent breaks rather than infrequent long breaks. Five-to-ten minutes away from repetitive work every hour is more effective than a single long break mid-shift. Microbreaks (10-30 seconds of different movement every 20-30 minutes) further reduce static loading.

3

Task Variation and Rotation

Where the same worker performs the same task all day, RSI risk is high regardless of individual technique. Varying tasks, rotating between different activities, and combining sedentary with standing or walking work substantially reduces risk.

4

Early Reporting and Response

The single most effective control is a culture where employees report discomfort early and employers respond promptly. Early intervention usually resolves RSI completely; late intervention often does not.

5

Training and Awareness

Workers who understand RSI, recognise early symptoms, and know how to adjust their workstation are significantly less likely to develop chronic conditions. DSE training and general ergonomic awareness are worthwhile investments.

6

Equipment Selection

Ergonomic keyboards, vertical mice, sit-stand desks, document holders, and monitor arms can reduce RSI risk but are not substitutes for good posture and work pattern management. Equipment changes should be based on individual assessment, not blanket provision.

BY SECTOR

RSI by
Workplace Type

RSI risk and appropriate controls vary by the nature of the work.

1

Office RSI

The most common context Arinite sees. Risks include DSE work (typing, mouse use, screen viewing), prolonged sitting, awkward postures at laptops or in home working setups, and cumulative exposure over long careers. Controls are primarily ergonomic workstation setup, break management, and early symptom response. DSE assessments are the statutory foundation.

2

Manual Handling and Production RSI

Repeated lifting, carrying, gripping, or twisting in production, warehousing, or distribution. Controls include mechanical assistance, task rotation, ergonomic redesign of workstations and processes, and manual handling training. TILE assessment (Task, Individual, Load, Environment) guides the analysis.

3

Healthcare RSI

Patient handling, equipment use, and repetitive clinical tasks. Healthcare has one of the highest RSI incidence rates of any UK sector. Hoists, slide sheets, adjustable beds, and comprehensive manual handling training are the foundation.

4

Laboratory and Technical RSI

Pipetting, microscope work, fine assembly, and repetitive sample handling. Task rotation, microbreaks, and ergonomic equipment (particularly for pipetting) reduce risk.
