How can I quantify muscle tightness? I'm mostly interested in forarm muscles.
I could ask a physical therapist to assess muscle tightness by touching the muscle. What are other solutions? The more objective and reproducible the measurement, the better.
Examples of use cases:
Use case 1: I want to study the impact of treatment X on muscle tightness. I would like to measure the muscle tightness before and after treatment X is applied.
Use case 2: I want to study the correlation between forarm muscles tightness and tendinopathy (epicondylopathy).
