This systematized review sought to better qualify and quantify the causal relationship between trigger-point (TP) needling efficacy and the local twitch response (LTR) regarding the upper trapezius muscle.

A systematized review is defined by the Duke University Medical Center Library and Archives as an attempt to include elements of the systematic review process while stopping short of a conventional systematic review.

The limited data utilized showed, preliminarily, that an LTR from needle insertion is a relative indicator of treatment success—as determined using a Visual Analogue Scale and measuring the patients’ ranges of motion, pre-treatment and post-treatment.

This review also noted that an LTR is a probable prerequisite for identifying effective TPs and a helpful hallmark in treating patients, resulting in peak benefit. However, this procedure can cause post-treatment, needling application-area tenderness.

Novel research should consider the number of LTRs resulting in dry needling (DN) maximal benefit at a specific TP. Finally, it is noted that utilizing 0.12 mm needles inhibits muscle soreness, mitigates patient anxiety concerning needling, and enhances needling therapy efficacy—as indicated in the comparison studies.
