A common extensor tendinopathy can be managed effectively by adhering to the following advice and exercise routine.
Modifying aggravating activities. If there are some particularly stressful tasks such as DIY or racket sports which seem to be aggravating your symptoms, then the common extensor tendon may need 4-6 weeks of relative rest.
Ergonomic adjustments. If the condition has been triggered by repetitive computer work, changes to your overall sitting position to ensure a neutral elbow and wrist position as well as some specialist keyboard and mouse equipment can significantly reduce the stresses placed on the common extensor tendon:
Appropriate DSE set up
Exercises. Regular exercises to strengthen the wrist extensor muscles and tendon in the forearm and stretch the flexor muscles:
3×15 repetitions 3-4x per week
5×30 second holds, 2x per day
These are suggested exercises only. If you are at all concerned about whether these exercises are suitable for you or if you experience any pain while doing them, please seek appropriate clinical advice from your GP or Physiotherapist.
Corticosteroid injection therapy. Evidence suggests that if possible, corticosteroid injections are best avoided as the steroid may weaken the tendon in the longer term. However, injections may be discussed with individuals who continue to suffer disabling pain (preventing work and leisure activities) and have failed physiotherapy management.
