Prospective, Randomized, Double-Blinded, Sham-Controlled Pilot Study of Intraneural Facilitation as a Treatment for Carpal Tunnel Syndrome.
Nancy A Baker, Diep Vuong, Mark Bussell and 3 others
PMID 35756982WHAT IT FOUND
Intraneural facilitation did not outperform sham exercises for carpal tunnel syndrome.
Both groups improved similarly over 3 months. The study was too small to confirm any benefit, so this technique is not yet supported as a superior treatment.
Key findings
01There was no significant difference in patient-reported outcomes between the intraneural facilitation group and the control group.
02Both the treatment and control groups showed improvement in clinical symptoms for up to 3 months.

What it does not show
The study included only 10 participants, making it underpowered to detect real differences. Participants had mild to moderate symptoms, excluding those with severe carpal tunnel syndrome who might respond differently. The sham intervention involved active exercises, which may have provided genuine therapeutic benefit, masking any additional effect of the specific manual holds. The follow-up period was short, potentially missing longer-term effects.

The easy way to misread this
Do not interpret the large effect size reported for pain scores at 1 week as proof of efficacy. This finding was derived from a very small sample and was not statistically significant when compared to the control group, which also improved.
