This video from the supplier of Flexibar describes an exercise that claims some improvements in tennis elbow pain from a Flexibar eccentric exercise. There are also references.
Some TW replies have had positive comments about the Flexibar for TE treatment. Also, eccentric exercise treatment is a research area with some current interest for chronic tendon injuries such as Achilles Tendon injuries.
Any thoughts on how eccentric exercise treatment might work for TE with the Flexibar? Effectiveness? Have you found other research from neutral sources on the subject?
