Why sessions start at 90 minutes.
The most useful study ever run on session length is a randomized dose-response trial published in the Annals of Family Medicine. Researchers took 228 people with chronic neck pain and assigned them to five weeks of massage at different lengths and frequencies, then measured who actually got better.
The result was blunt. Thirty-minute sessions accomplished nothing measurable, even at two or three visits a week; statistically, they matched the wait list. Sixty-minute sessions were a different story: people receiving them three times a week were roughly five times more likely to achieve meaningful improvement in function than untreated controls, and nearly three times more likely to see meaningful pain relief.
Just as telling was the shape of the results. More delivered more. Sixty minutes beat thirty, three visits a week beat two, and two beat one. Every step up in time and frequency the trial tested produced better outcomes.
That is the research behind Kinetic's recommendation that sessions begin at 90 minutes. The recommendation takes the fully tested hour of focused treatment and wraps it in what a thorough visit actually requires: movement assessment before, re-checking after, and work at a pace tissue tolerates. To be straight about the limits, no trial has timed a 90-minute session; what the evidence proves is the direction, and the direction is that thorough, consistent work wins.
And when a shorter session makes clinical sense for an established client between full visits, Kinetic accommodates it. The recommendation exists because thoroughness is what the evidence rewards, not because flexibility is forbidden. The full approach lives here.
