![]() These results indicate that injections given before electrodiagnostic testing alter results and may affect patient management. To cite but one example of many, an EMG or NCS is irrelevant as a first order diagnostic test for limb pain resulting from immediate antecedent trauma or acute. Our study results showed a statistical difference between testing done before and after steroid injection. Both differences were statistically significant (paired t test). Mean (SD) difference between preinjection and postinjection DML was 0.187 (0.45) ms, and mean difference between preinjection and postinjection PSL was 0.319 (0.48) ms. After injection, mean (SD) DML was 4.82 (0.7) ms, and mean (SD) PSL was 4.69 (0.66) ms. Before injection, mean (SD) distal motor latency (DML) was 5.01 (0.9) ms, and mean (SD) peak sensory latency (PSL) was 5.01 (0.88) ms. All data from the electrodiagnostic studies were entered into a database and used for comparison. ![]() Repeat studies were performed 4 to 6 weeks after injection. Twenty-seven patients underwent testing before and after injection. ![]() One hundred forty-five patients with suspected CTS were targeted for this study. We conducted a study to determine the change in nerve conduction testing after steroid injection in patients with carpal tunnel syndrome (CTS).
