Flexibility is usually the first thing people associate with stretching, so it's worth looking at what general research actually says — and being honest about where the evidence is strong and where it's more limited.
What the Evidence Generally Shows
Mayo Clinic notes that stretching can help improve flexibility and, as a result, the range of motion of your joints. Assisted stretching applies that same underlying principle, with a practitioner helping you reach an effective stretch position more reliably than doing it alone.
Why Consistency Matters More Than Intensity
Flexibility gains generally aren't permanent from a single session. Mayo Clinic points out that stretching benefits require consistency — roughly two to three times a week — to maintain over time. A single, intense session is far less valuable than a regular habit.
What Assisted Stretching Doesn't Guarantee
It's worth being direct about the limits here: stretching, assisted or otherwise, has not been shown to reliably prevent injuries or reduce post-exercise soreness, and general research on how flexibility gains translate into specific outcomes like athletic performance is still mixed. Assisted stretching can help you move more comfortably and access a fuller range of motion — it isn't a guarantee of fewer injuries, a lower golf handicap, or more distance off the tee.
The evidence supports stretching as a way to build and maintain flexibility over time. It doesn't support broader claims about injury prevention or performance that go beyond that.
