What You Should Be Able to Explain After Reading
- Recognize a common extensor tendinopathy pattern while keeping the diagnosis provisional.
- Screen cervical, neural, intra-articular and systemic alternatives.
- Build a progressive loading plan tied to grip and work demands.
- Use repeatable outcome measures and clear referral thresholds.
Clinical framework and anatomy
- Lateral elbow tendinopathy commonly involves the common wrist-extensor origin, particularly extensor carpi radialis brevis. Symptoms do not prove a specific microscopic lesion, and persistent pain should not automatically be described as inflammation.
- Pain is often reproduced by gripping, lifting with the forearm pronated or resisted wrist extension. Symptoms may fluctuate with cumulative load and recovery.
History, examination and outcomes
- Ask about onset, recent increases in gripping or tool/racquet use, recovery, pain at rest, sleep, neck symptoms, paresthesia and the tasks most limited.
- Assess local tenderness, resisted wrist extension, grip strength and relevant cervical, shoulder, elbow and neurological findings. Provocation tests support a pattern but no single test confirms the diagnosis.
- Track PRTEE or QuickDASH, pain-free grip where feasible and a patient-specific task such as lifting a kettle or using a tool.
Differentials and safety
- Consider radial tunnel/posterior interosseous nerve disorders, cervical radiculopathy, radiocapitellar pathology, referred shoulder pain and inflammatory conditions when the pattern is atypical.
- Prompt medical review is appropriate after significant trauma, with deformity, a hot swollen joint or fever, progressive neurological deficit, unexplained mass or severe unremitting pain.
Management and dosage
- Explain the likely load-related pattern and agree temporary modification of the most provocative volume or grip force while maintaining tolerable daily activity.
- Begin with tolerable wrist-extensor isometrics or slow isotonic resistance, then progress to concentric/eccentric or heavier resistance as capacity improves. A pragmatic starting option is 2–3 sets of 8–15 controlled repetitions on 2–3 days per week, adjusted to irritability and response rather than treated as a universal protocol.
- Progress resistance, repetitions, grip demand and task specificity one variable at a time. Manual therapy may provide short-term symptom modulation for some people but should support, not replace, active rehabilitation.
Reassessment, precautions and common errors
- Review symptoms during exercise and over the following 24 hours; reduce dose if a flare is substantial or sustained. Reassess PRTEE/QuickDASH, grip and the chosen task every 2–4 weeks.
- Avoid diagnosing from one positive Cozen, Mill or Maudsley test, prolonged immobilization, repeated painful testing or promises that eccentric exercise is uniquely superior. Reconsider the diagnosis if function worsens or progress stalls.
Clinical pearl and summary
- The useful endpoint is restored capacity for meaningful gripping and lifting, not a pain-free provocative test in isolation. Match loading to irritability, document progression criteria and escalate atypical presentations.
