Peroneal Tendon Muscle Testing Technique

     I hope my new video on peroneal tendon muscle testing is helpful. There can be big differences in the treatment of peroneus longus and peroneus brevis tendonitis conditions. Also, MRIs tend to imply that some peroneal tendons are torn, when they are not. I have had MRI reports say that one of the tendons is completely torn only to find out it is very strong on testing.
    Treatment of tendonitis has both general rules and specific rules for that tendon. The General rules are covered by the BRISS principles summarized in the link below. 

     Treatment of tendonitis also has specific rules based on the function of the tendon. What does the peroneus brevis do where it can become over worked and strain? The peroneus brevis stabilized the lateral ankle, rear foot and mid foot. Lateral instability or just lateral overload of the foot due to the biomechanics of the foot or an activity can stress it causing strain.
     The peroneus longus does the same lateral ankle and rear foot protection, but is a crucial tendon in arch support. Therefore, arch collapse problems and cuboid problems can cause the peroneus longus to strain. 
     The peroneal tendons can also hurt as they protect a sore joint (either arthritic or functional jamming). It is important to remember that any tendonitis may be the superficial presentation of a deeper problem. See the post below on the “Tip of the Iceberg” where the Achilles’ tendonitis is used as the example. 
I have had many cases where the initial diagnosis of peroneal tendonitis was eventually changed to subtalar joint problems. The peroneals were only protecting the joint and their inflammation was due to overwork protecting the joint. 

Next week I will discuss peroneal taping and the week after peroneal strengthening. I hope this helps someone.
