A small controlled study compared benzodiazepine treatment, cupping, and a wait list. Shared imaging changes did not establish identical mechanisms or therapeutic equivalence.
Sixty-seven patients with primary insomnia were randomized for four weeks. Both active groups had lower sleep-quality questionnaire scores than the wait-list group, without a significant difference between the active treatments.
The investigators reported shared changes in hippocampal functional connectivity associated with symptom improvement. A gray-matter difference was reported for the cupping group.
A correlation between connectivity and a questionnaire does not prove that the network change caused relief. Nor does a nonsignificant treatment difference demonstrate formal equivalence. A wait list does not control all expectations or attention effects.
The small sample and short follow-up limit durability and safety conclusions. The study did not establish identical receptor actions or benzodiazepine-like potency for cupping. Its contribution is a treatment-associated imaging observation, not a diagnostic scan for medication response or proof that either approach restores every aspect of sleep.
