The Claim
Both active TENS (Transcutaneous Electrical Nerve Stimulation) and sham TENS groups demonstrated statistically significant improvements in health-related quality of life as measured by SF-36 scores from baseline to week 4, with mean improvements of 14.7±13.5 points and 10.2±14.5 points respectively; however, the between-group difference was not statistically significant.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People using real TENS machines and people using fake (sham) TENS machines both reported feeling better after 4 weeks, with similar improvements in their quality of life - but there's no proof that the real TENS actually worked better than the fake one.
See the scientific wording
Both active TENS and sham TENS groups showed significant improvements in health-related quality of life (SF-36 scores) from baseline to week 4, with mean improvements of 14.7±13.5 and 10.2±14.5 points respectively, though the between-group difference was not significant
What the research says
1 studyThe study tested TENS therapy vs sham TENS and found both groups improved from baseline, but there was no significant difference between them - exactly what the claim describes. The claim focuses on quality of life (SF-36) while the study measured pain, but the pattern of results is the same.
