Avoiding repetitive strain injury

Avoidance does not require holding one supposedly perfect posture all day. Muscles and tendons generally cope better when position, force and activity change regularly.

Repetitive strain injury is a broad term for pain or irritation associated with repeated movement, sustained posture, forceful gripping, vibration or too little recovery. Symptoms may include aching, burning, stiffness, tingling, weakness or reduced grip. The pattern can involve the hand, wrist, forearm, elbow, shoulder or neck.

A task is not automatically harmful because it is repeated. Risk rises when several demands combine, such as high force, awkward reach and long uninterrupted periods, especially after a sudden increase in workload.

Bring frequently used items within easy reach, support the forearms when practical, keep wrists near a neutral position and use a light grip. Adjust the chair, work surface and screen to suit your body and task rather than forcing your body around fixed equipment.

Alternate demanding work with lighter activity, take brief movement breaks before discomfort builds and increase a new task gradually. For tools, choose a handle size that permits a relaxed grip and keep cutting edges or mechanisms in working order so less force is needed. Outside work, sleep, general activity and progressive strengthening can support recovery capacity.

Arrange a clinical assessment if symptoms persist despite changing the task, repeatedly return, disturb sleep or affect grip and hand control. Seek prompt care for new marked weakness, spreading numbness, a cold or discoloured hand, severe swelling, or pain after a significant injury.

A clinician can examine the pattern and check for a more specific problem affecting a tendon, muscle, joint or nerve. Early adjustments may prevent a mild irritation from becoming harder to manage.

Ask which movements or loads appear to provoke your symptoms, whether sensation and strength are normal, and how to modify work while staying active. You can also ask whether a workplace assessment, exercise plan or temporary change in duties would fit your situation.
