Objective:

To compare the short-term effects of sliding cupping therapy and narrowband ultraviolet B (NBUVB) phototherapy on plaque psoriasis.

Approach:
    Key Findings:
    • Mean PASI scores decreased by 62% in the cupping group and 67% in the NBUVB group by week 8.
    • 69% of cupping patients and 79% of NBUVB patients achieved at least a 30% improvement in PASI scores.
    • Both treatments showed comparable improvements in PASI scores, body surface area involvement, Physician’s Global Assessment scores, and itch severity.
    • Adverse events were mild and infrequent, with no serious adverse events reported.
    Interpretation:

    Sliding cupping therapy may provide similar short-term benefits for plaque psoriasis as NBUVB, but the mechanisms remain unclear and should be interpreted cautiously.

    Limitations:
    • The trial was small and conducted at a single center.
    • Short-term follow-up limited the assessment of long-term effects.
    • Baseline disease severity was relatively modest and the population was predominantly Chinese.
    • The study was not fully blinded and cupping is operator-dependent.
    Conclusion:

    Sliding cupping and NBUVB were associated with similar short-term clinical outcomes, but further larger and longer-term studies are needed to clarify the role of cupping therapy in psoriasis treatment.
