Prediction Model for Minimizing the Risk of Median Nerve Puncture

Ultrasound and Anthropometric Prediction Model for Minimizing the Risk of Median Nerve Puncture With Dry Needling Approach Into the Pronator Teres Muscle

The main aim of this study was to correlate anthropometric measures of the forearm in healthy subjects with the ultrasound pronator teres depth to determine the needle length in order to avoid injury of the median nerve during pronator teres dry needle approach. A cross-sectional study, was carried out in order to perform a predictive model for the median nerve depth into the pronator teres muscle using a decision tree analysis algorithm.
