Scraping therapy eased insomnia scores, but safety went unrecorded

Insomnia is a common chronic condition affecting an increasing number of people, and plenty of them look beyond conventional sleep medicine for relief. Holographic scraping, a therapy drawn from traditional Chinese medicine, is already widely used in people with insomnia, yet its efficacy has been genuinely controversial. Until now, nobody had systematically pooled the trial evidence to see whether it works or whether it is safe. A therapy in wide use deserves the same scrutiny as any other treatment, which is the gap this review set out to close.

Two researchers searched eight databases, spanning major international sources and Chinese-language databases, from their establishment up to June 2024, looking for randomised controlled trials of holographic scraping in people with insomnia. Twenty-two trials involving 1816 participants met the criteria and were included. The risk of bias in each trial was judged with the Cochrane Risk of Bias Assessment Tool 2.0, the results were pooled statistically, and the overall certainty of the evidence was rated using the GRADE system.

Holographic scraping came out ahead on the Athens Insomnia Scale and on anxiety and depression rating scales, and the pooled total effective rate favoured the therapy. When combined with health education or usual care, it may also reduce scores on the Pittsburgh Sleep Quality Index, a standard measure of sleep quality. However, when combined with medication or auricular acupressure, its effect on that same sleep quality index remained controversial. Crucially, only 2 of the included studies reported adverse effects, so the review could not establish whether the therapy is safe.

This is the first systematic pooling of the trial evidence on holographic scraping for insomnia, and it lands in a familiar place for traditional therapies: encouraging symptom scores, patchy findings on the harder outcome of measured sleep quality, and near-silence on safety. The authors themselves flag that the sleep quality picture depends on what the therapy is combined with. The open questions are clear: whether better trials confirm the effect, and whether side effects are genuinely rare or simply unreported.

If you have heard of scraping therapies and wondered whether the evidence backs them for sleep, the honest answer is that it is suggestive but unfinished. Symptom scales moved in the right direction across 22 trials, which is more than many alternative therapies can show. At the same time, the effect on sleep quality itself was inconsistent, and the safety record is close to blank. This is a reason to treat holographic scraping as an actively studied but unproven option, not an established one.
