Stress vs Strain

Post by ritalafaive »

Hi. I listened to a podcast where Bernie mentioned a study by Dr Kao (sp?)... where the results were stressing the tissues about 3% and holding for time was the optimized situation for healing. I may have gotten some of the facts wrong which is why I am interested in getting a link/copy of the study. Any chance that is still available?

Have a great day,
Rita

Hi Rita

A 2015 study * was done to answer the question of how much stretch and for how long is optimal to reduce pain, increase range of motion and improve physiologic function of joints. Myofascial release (MFR) is a physical therapy using long-held, static stretches. It was employed to stress joints and was shown to reduce inflammation and improve healing response to injury.

The researchers found that a strain (elongation) of 3% held for 5 minutes is ideal. Stresses above that level, which created a strain of 9% or 12% (that is a lot!), can cause problems, but a stress resulting in only a 3% strain can accelerate healing. The longer the stress is applied the better. The lengths of time varied from 1 to 5 minutes. This, in our Yin Yoga context, means less effort and longer holds are better. The researchers concluded, “Longer duration of MFR resulted in rapid decreases in wound size.”

* Thanh V. Cao et al., “Duration and Magnitude of Myofascial Release in 3- Dimensional Bioengineered Tendons: Effects on Wound Healing,” The Journal of the American Osteopathic Association 115.2 (2015): 72–82.

Cheers, Bernie

The effects of stress on our lives are devastating. I haven't read anything about this study, but it seems to be an interesting one. Too much cortisol in our lives is not good. I also went through enormous stress during the pandemic. I lost my job, I often argued with my wife. That lasted a few weeks until we both decided to take control of the situation. And we started looking for solutions online to find a therapist. We looked over this article https://www.lamag.com/sponsored/best-online-therapy/ and found some recommendations. We registered on the Talk Space platform, and the very next day, we talked to a specialist. Since then, our lives have improved.
