- Browse by Product or Use Case: Use filters or categories to explore studies linked to each technology (e.g. CES, MET, HBOT, red light, cryotherapy).
- Track the Evidence Quality: We reference the evidence pyramid (RCTs, meta-analyses, open-label studies, case reports) so you can assess the strength of each source at a glance.
- Download Full Studies: Where available, we provide links to full-text publications or summaries on platforms like PubMed, ResearchGate, or journals.
- Use in Clinical or Commercial Settings: This library supports B2B partners, helping you build confidence in the tools you use with clients or patients.
- Stay Updated: As new research emerges, we continually update this archive to reflect the latest findings.
Evidence Level
Evidence Level refers to the type of study design. Different types of studies provide different strengths of evidence.
Quality Rating
Quality Rating reflects how much confidence we can place in the evidence level overall.
- High: Synthesises multiple studies or uses strong, controlled methods.
- Moderate: Provides useful findings but with some design limitations.
- Low: Offers early signals or context, but carries higher risk of bias.
Together, the Level tells you what type of study it is, and the Quality Rating helps you understand how reliable it is likely to be.
Evidence Levels and Quality Ratings
High Quality
- Systematic Review / Meta-analysis – Synthesises multiple RCTs or high-quality trials with consistent results.
- Randomised Controlled Trial (RCT) – Prospective, randomised comparison of interventions.
Moderate Quality
- Controlled Trial (Nonrandomised) – Prospective controlled design without randomisation.
Low Quality
- Prospective Observational / Open-label – No randomisation; may lack control group.
- Case Series / Case Report – Descriptive reports of small numbers of cases.
- Mechanistic / Imaging (no clinical endpoint) – Physiology or neuroimaging studies; not designed to show clinical effect.
- Narrative Review / Editorial – Expert summary without systematic methodology.
- Methodological Review – Discusses methods/statistics rather than outcomes.
- Thesis / Dissertation (non–peer reviewed) – Academic theses; variable quality; not peer reviewed in journals.
Important Notes
- We only include studies that reflect the exact device or methodology used in our protocols. (e.g. Alpha-Stim research does not generalise to all CES devices.)
- Inclusion of a study does not imply product claims — it exists to inform, not market.
- Where products are NHS-used, NICE-referenced, or CE/FDA-cleared, we include those regulatory notes separately.
