What the research actually shows
All groups received usual physiotherapy comprising open- and closed-chain exercises, so the control was not no treatment. Retro walking was added three times weekly for six weeks. A senior physical therapist blinded to allocation recorded all outcomes. Inclusion of therapeutic ultrasound in the control could not be verified from the full-text evidence.
Why this is classified as C (54)
The grade is C with 54 points. The cited primary source was checked directly; see the Korean text and evidence table for exact arm-level results.
Counterpoint. Important limitations and alternative evidence are reported in the Korean text.
Rejudgment record. Cross-check applied — Direct source-checked evidence and prespecified axis profile
| Endpoint | P | Symptom or function itself is the target - including patient reports and performance tests |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
Stored derived and displayed grades match; this is not a current recalculation or validity check (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Primary claim | C | The grade is C with 52 points. The cited primary source was checked directly; see the Korean text and evidence table for exact arm-level results. |

What this document does and does not do
Chamgap is an information source. It reports what research has and has not confirmed; it does not tell readers what to take or buy. That decision belongs to readers and, when needed, medical or legal professionals. This verdict reflects literature available up to the search date and may change as new research appears. Nothing here is medical advice.
