The correlation between Motor Unit Potentials (MUP) duration, assessed by EMG in the deltoideus and the biceps brachii, and upper extremity functional test of PUL 2.0 in three DMD patients from baseline up to 12 months after systemic–intraosseous administration of the DT-DEC01 therapy. The correlation analysis between MUP duration and PUL 2.0 test confirmed: A a strong and significant correlation between the increase in MUP duration recorded in the deltoideus muscle and the improved functional outcomes assessed by the PUL test (correlation coefficient r = 0.977, P = 0.023), B a strong correlation between the increase in MUP duration recorded in the biceps brachii muscle and the improved functional outcomes assessed by the PUL test (correlation coefficient r = 0.882; P = 0.118) up to the 12 months after DT-DEC01 therapy administration. The Pearson correlation coefficient was used to assess the correlation. Square points indicate correlation of PUL 2.0 outcomes and MUP duration in (A) deltoideus muscle and in (B) biceps brachii. Linear regression is presented with solid line for (A) deltoideus muscle correlation (Y = 0.2045 × X + 80.10) and for (B) biceps brachii correlation (Y = 0.1379 × X + 87.82) and with 95% confidence interval indicated by dotted line.
