Treatment of recurrent tendinitis by isokinetic eccentric exercise. Croisier J-L, Forthomme B, Foidart-Dessalle M, Godon B, Crielaard J-M. Isokinetics and Exercise Science. 2001;9:133-141. 

Diagnosis:  9 Achilles, 10 patellar, and 15 lateral epicondyllar

Outcome:  15/34 patients had complete relief of symptoms, 10/34 had marked decrease in symptoms, 5/34 had moderate decrease in symptoms, and 4/34 had no change in symptoms.

When Assessed:  After 20 to 30 sessions, which should be ~7-10 weeks. Follow up for return to sporting activities was “after 3 months of practice”.

Subjects:  34 patients, 9 Achilles, 10 patellar and 15 epicondyllar. No blinding and no control group.

Protocol:  Isokinetic eccentric exercise 3x per week, 1-5 sets of 10-30 reps, increasing speed and intensity over time. 20-30 sessions. Comanaged with ice, TENS, ultrasound, massage and stretching.

Other Activity:  “Subjects were instructed to avoid provoking pain or discomfort in the course of activities between training sessions.”

Chad’s Comments:   Reported they generally noted a significant decrease in pain by the 10th session. Did exercises just 3x per week to good effect. Found roughly the same effectiveness regardless of tendinitis type.

Thanks for reading my blog. If you have any questions or comments (even hostile ones) please don’t hesitate to ask/share. If you’re reading one of my older blogs, perhaps unrelated to neck or back pain, and it helps you, please remember Spinal Flow Yoga for you or someone you know in the future.

Hello! Thanks for checking out Spinal Flow Yoga®!

This is one of my older “legacy” blogs from my prior physical therapy site. If the information you find here seems only moderately related, or a bit technical for yoga, it’s because I wrote it with a different, but still overlapping, audience in mind. However, I think each blog does showcase my thought processes and research base, both of which very much influenced what evolved into Spinal Flow Yoga®.

Further, given that spine pain has long been a favorite topic of mine, much of the content within these older blogs will be directly relevant to Spinal Flow® even if at times I criticized yoga. In fact, that’s why I created Spinal Flow Yoga®, to correct what were, and still are, many physical problems in modern yoga sequences. Time permitting, I may revisit some of my favorites blogs add some content relating them to newer Spinal Flow® concepts that aim to cure neck and back pain as well as improve overall health and fitness from the comfort of your own home without the need for equipment. Hopefully that will make more sense out of why this blog is here. And if you have neck or back pain, you're in luck. Before you needed a gym to utilize my methods, but I've been working hard, gearing it towards home training, and efficiency and effectiveness have been remarkable. Hit the button to learn more about SC5 and SF5, my 5-minute flows, both of which I'm very proud of.
