Manual therapy is recognized in clinical guidelines, but primarily as a short-term adjunct within multimodal care — not as a standalone treatment with durable long-term benefits. Multiple umbrella reviews and systematic reviews show that MT's effects tend to diminish over time, losing statistical significance by 13–52 weeks. Methodological concerns — including difficulty with blinding, inadequate controls, and short follow-up periods — may also inflate apparent effectiveness. The claim's assertion of "long-term treatment benefits" is not supported by the weight of current evidence.
