Résumé : |
Objective To determine the relation between the patient's actual pain, the electromyographer's perception of patient pain, and whether an electromyogram (EMG) is altered. Design Patients undergoing electromyography reported expected pain and procedure-related overall pain on a 100-mm visual analog scale (VAS). Blinded electromyographers estimated patient pain levels and indicated if they altered the study in any way because of this perception. Multivariable logistic regression was used to determine predictors of altering the EMG. Paired t tests were used to compare overall pain with expected pain and electromyographer perception of pain. Setting Tertiary referral center. Participants Referred sample of adult subjects (N=304). Interventions Not applicable. Main Outcome Measures Patient pain, electromyographer perception of patient pain, and whether an EMG was altered because of the electromyographer's perception of patient pain. Results Mean VAS scores + SD were 48+25mm for patient-expected pain (P<.001 for electromyographer perception of pain and actual overall pain. electromyographers altered their study the time because concerns about every increase on vas prespecified clinically meaningful difference increased odds altering a times confidence interval whereas patient did not have significant effect ratio="1.12;" ci .86> Conclusions Patients expect EMGs to be more painful than they are. Electromyographers overestimate patient pain and are more likely to alter their studies when they believe patients are experiencing more pain, independently of whether patients actually have more pain. Improving the communication between electromyographers and patients may prevent unnecessary alterations. |
