Conservative Treatments of Carpal Tunnel Syndrome: A Systematic Review and Network Meta-analysis.

Carpal tunnel syndrome causes pain and numbness in the hand from nerve compression at the wrist, and clinicians have long debated which non-surgical treatment works best when surgery isn't the immediate choice. This review pooled 49 randomized trials covering eleven different conservative treatments, including manual therapy, steroid injections, platelet-rich plasma injections, shockwave therapy, and low-level laser therapy, comparing them all at once through a network meta-analysis so treatments could be ranked even when they hadn't been tested head-to-head in the same trial. Manual therapy ranked highest for easing pain in both the short and medium term, with dextrose 5% in water injections and platelet-rich plasma close behind. Shockwave therapy and low-level laser therapy also showed benefit compared with control groups.

The findings are interesting because they suggest hands-on treatment may hold its own against injection-based approaches, but the analysis relies on indirect comparisons across many small trials, and the authors themselves note that longer-term outcomes and cost-effectiveness still need dedicated study.

If you're dealing with carpal tunnel syndrome, the tingling and numbness in your hand and fingers that comes from pressure on a nerve at the wrist, you may be weighing which non-surgical treatment might help before considering anything more invasive. This study looked at evidence from 49 clinical trials testing eleven different conservative treatments, including manual therapy, injections like steroids or platelet-rich plasma, shockwave therapy, and low-level laser therapy, to see how they compared for relieving pain. Manual therapy came out ranked as the most effective option for pain relief in both the short and medium term, with a sugar-water injection called dextrose 5% and platelet-rich plasma injections following closely.

Shockwave therapy and low-level laser therapy also showed benefit compared with doing nothing. What's encouraging is that a hands-on approach performed at least as well as more invasive injection treatments in this analysis. That said, this comes from combining many separate, generally small trials rather than one large head-to-head comparison, and the researchers note that we still don't know how these treatments compare over the long run or how their costs stack up against each other.

This network meta-analysis pooled 49 randomized controlled trials (n=3323) evaluating 11 conservative treatments for carpal tunnel syndrome, using surface under the cumulative ranking curve (SUCRA) values to rank relative efficacy for pain outcomes since many treatments were never compared directly. Manual therapy ranked highest for pain relief at both short-term (SUCRA 87.6%) and medium-term (SUCRA 99.3%) follow-up, with dextrose 5% in water and platelet-rich plasma injections ranking closely behind, though exact SUCRA values for these were not reported in the abstract. Against control, low-level laser therapy showed a standardized mean difference of -1.45 (95% CI, -2.16 to -0.74) and extracorporeal shock wave therapy showed -1.03 (95% CI, -1.86 to -0.20), both statistically significant.

Because SUCRA rankings derive from indirect network comparisons rather than consistent head-to-head trials, clinicians should treat the manual therapy ranking as an indication of relative probability of being the top-performing option within this specific evidence network, not a certainty of superiority in direct comparison. The authors themselves flag that long-term efficacy and cost-effectiveness remain unassessed, and the review does not report on risk of bias or heterogeneity across the 49 included trials, which limits how confidently these rankings can be generalized to practice.
