How long is long enough?

Thirty seconds, two minutes, three minutes: the research notes contain all of these. They come from different tools, body areas, populations, and teaching methods. They are not interchangeable prescriptions.

Different protocols ask different questions

An umbrella review describes substantial variation in rolling duration, pressure, speed, and frequency. That variation limits the case for one universal dose. We retain a source’s context when a guide includes timing.

A method rule is not an established optimum

Block Therapy describes a minimum three-minute hold as part of its own method. That establishes what the provider teaches; it does not establish that three minutes is necessary or appropriate for every person or body area.

Use comfort as a reason to adjust

A guide’s suggested duration is never a reason to persist through pain. Reduce pressure, change the setup, or stop. Record what you actually did if you want to discuss the response with a clinician.
