What do you mean by "muscle tone density"? It is not a scientific term, at least not in English.

Check shearwave elastography,

Also check miotonometer.

Yes, the effects of flexibility exercises on the facia can be measured but it is very hard and to observe differences the exercises must last very long. Myo-elastography is not the best way to assess the fascia tensile stress modulus. Moreover the deep fascia is a very thin layer of tissue which is very hard to target with ultrasounds.

Recently it has been demonstrated that flexibility exercises may target mainly the fascia profundis. Stecco C, Pirri C, Fede C, Yucesoy CA, De Caro R, Stecco A. Fascial or Muscle Stretching? A Narrative Review. Applied Sciences. 2021; 11(1):307. https://doi.org/10.3390/app11010307.

For example we could observe but during quadriceps stretch in the main street structure was the fascia lata. You may find explanations about that in an article we wrote recently: What mechanical and proprioceptive structures are involved in quadriceps stretching? Why is it important for patella travel?

We could also demonstrate that the participants stretch tolerance depended mostly on the fascia profundis taut surfaces. Stretch tolerance and elastic passive reaction of the quadriceps femoris seem to depend more on the fascia profundis taut surfaces than on the underlying stretched muscle

The simplest way to assess elastic characteristics of the fascia is to conduct extensibility test and to measure elastic modulus. This must be done on a structure where the target of a stretch is clearly identified.
