Distinguish tendon, symptom and diagnosis
Upper-limb disorders include tendon problems and other conditions, such as nerve compression. Pain or loss of movement alone cannot identify the affected structure. Not every arm or wrist complaint should be called tendinitis.
INSST clinical guidelines distinguish, among other conditions, rotator cuff disorders, epicondylitis and thumb tenosynovitis. They are intended for healthcare professionals and help connect clinical information with exposure factors and occupational history.
Reconstruct the complete task
Observe which movements are repeated, how much force they require and the posture in which they are performed. Duration, pace, grip, reach and recovery opportunities matter. The same job title may cover very different operations.
HSE notes that several factors can act together. A short task is not automatically acceptable if it requires considerable force. Observation should include normal production, peaks, tool changes and difficulties people routinely overcome.
Choose an assessment suited to the problem
Methods for repetitive tasks help identify factors and prioritise changes, but their results are not diagnoses. Check whether the procedure covers all relevant demands and represents the actual working day.
Exposure data need an understandable description: operation observed, duration, conditions and limitations. This allows a modification to be reviewed without comparing scores derived from different situations or criteria. Participation by the person doing the work can reveal effort that is hard to see externally.
Modify work and check the effect
Review workstation design, tools, supports, access to materials and activity organisation. The aim is to reduce identified demands, not merely remind people to work carefully.
Rotation provides preventive variety only if it genuinely changes the load. Moving between two operations requiring the same grip may retain the problem. After introducing an aid, check that it does not shift effort to the shoulder or require another unfavourable posture.
Address discomfort and adjust without labelling
Make it easy to report difficulties and obtain medical assessment. The prevention service needs task and exposure information; operational managers need to know the required measures, while clinical confidentiality is respected.
If adjustment or return after absence is needed, define working conditions and review implementation. Do not presume incapacity from a disease label or normalise working in pain. Individual progress and assessment of conditions are related processes with different professional functions.
Hypothetical example: an assembly operation
A team reports discomfort while holding parts and using a tool. Assessment identifies a sustained grip and difficult reach. A support is trialled and the supply position changed.
Checks include people on different shifts and record whether the new arrangement reduces effort without introducing other risks. Those experiencing discomfort receive appropriate medical guidance. Workplace improvement is not conditional on assigning a diagnosis to the entire team.
