Altering Electromyography Studies: Importance of the Electromyographer's Perception of Patient Pain / Zachary N. London in Archives of Physical Medicine and Rehabilitation, 2014/1 (2014)  

[article]  inArchives of Physical Medicine and Rehabilitation > 2014/1 (2014) . - pp. 39-42 Titre : Altering Electromyography Studies: Importance of the Electromyographer's Perception of Patient Pain Type de document : Article Auteurs : Zachary N. London ; Rebecca Hazan ; James F. Burke ; [et al.] Article en page(s) : pp. 39-42 Langues : Anglais (eng) Descripteurs : HE Vinci Douleur ; Electromyographie ; Pain ; Rééducation et réadaptation Mots-clés : Electromyography 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.

Comparison of the Effects of Vapocoolant Spray and Topical Anesthetic Cream on Pain During Needle Electromyography in the Medial Gastrocnemius / Young-Eun Moon in Archives of Physical Medicine and Rehabilitation, 2013/5 (2013)  

[article]  inArchives of Physical Medicine and Rehabilitation > 2013/5 (2013) . - pp. 919-924 Titre : Comparison of the Effects of Vapocoolant Spray and Topical Anesthetic Cream on Pain During Needle Electromyography in the Medial Gastrocnemius Type de document : Article Auteurs : Young-Eun Moon ; Sang-Hyun Kim ; Won-Hyeok Choi Article en page(s) : pp. 919-924 Langues : Anglais (eng) Descripteurs : HE Vinci Electromyographie ; Perception de la douleur ; Rééducation et réadaptation Mots-clés : Anesthetics  Local  Anesthésiques locaux  Electromyography  Pain Perception Résumé : Objective To compare the effects of a vapocoolant spray and an eutectic mixture of local anesthetics (EMLA) cream in reducing pain during needle electromyography examination. Design Randomized controlled trial. Setting Physical medicine and rehabilitation department of a university hospital. Participants Adults who underwent needle electromyography (N=99) were randomized to 1 of 2 experimental groups or the control group. Two patients dropped out during the study. Interventions In the experimental groups, vapocoolant spray or EMLA cream were applied before needle electromyography. In the control group, needle electromyography was performed without pretreatment. Main Outcome Measures Intensity of pain associated with needle electromyography was assessed using a 100-mm visual analog scale (VAS). Patient satisfaction and preference for repeated use were measured using a 5-point Likert scale. Results VAS score for pain intensity was significantly lower in the spray group (31.9; 95% confidence interval [CI], 22.0–41.7) compared with the control group (52.9; 95% CI, 45.9–60.0; P=.002), whereas there was no significant difference between the EMLA cream group (42.4; 95% CI, 34.2–50.7) and the control group. Patient satisfaction and preference for repeated use were higher in the spray group than the EMLA group. Conclusions Vapocoolant spray was more effective than EMLA cream in reducing pain during needle electromyography.

[article]  inArchives of Physical Medicine and Rehabilitation > 2014/8 (2014) . - p. 1521-1526 Titre : Diagnostic Accuracy of the Electromyography Parameters Associated With Anterior Knee Pain in the Diagnosis of Patellofemoral Pain Syndrome Type de document : Article Auteurs : Deisi Ferrari ; Heloyse Uliam Kuriki ; Cristiano Rocha Silva Article en page(s) : p. 1521-1526 Langues : Anglais (eng) Descripteurs : HE Vinci Electromyographie ; Rééducation et réadaptation ; Sensibilité et spécificité Mots-clés : Patellofemoral Pain Syndrome  Syndrome fémoro patellaire  Electromyography  Sensitivity and Specificity Résumé : Objective To assess the diagnostic accuracy of the surface electromyography (sEMG) parameters associated with referred anterior knee pain in diagnosing patellofemoral pain syndrome (PFPS). Design Sensitivity and specificity analysis. Setting Physical rehabilitation center and laboratory of biomechanics and motor control. Participants Pain-free subjects (n=29) and participants with PFPS (n=22) selected by convenience. Interventions Not applicable. Main Outcome Measure The diagnostic accuracy was calculated for sEMG parameters’ reliability, precision, and ability to differentiate participants with and without PFPS. The selected sEMG parameter associated with anterior knee pain was considered as an index test and was compared with the reference standard for the diagnosis of PFPS. Intraclass correlation coefficient, SEM, independent t tests, sensitivity, specificity, negative and positive likelihood ratios, and negative and positive predictive values were used for the statistical analysis. Results The medium-frequency band (B2) parameter was reliable (intraclass correlation coefficient=.80–.90), precise (SEM=2.71–3.87 normalized unit), and able to differentiate participants with and without PFPS (P<.05 the association of b2 with anterior knee pain showed positive diagnostic accuracy values .87 sensitivity .70 negative likelihood ratio .33 predictive value .72 and .86> Conclusions The results provide evidence to support the use of EMG signals (B2 – frequency band of 45–96Hz) of the vastus lateralis and vastus medialis muscles with referred anterior knee pain in the diagnosis of PFPS.

Incremental Ability of Needle Electromyography to Detect Radiculopathy in Patients With Radiating Low Back Pain Using Different Diagnostic Criteria / Henry Tong in Archives of Physical Medicine and Rehabilitation, 2012/6 (2012)  

[article]  inArchives of Physical Medicine and Rehabilitation > 2012/6 (2012) . - pp. 990-992 Titre : Incremental Ability of Needle Electromyography to Detect Radiculopathy in Patients With Radiating Low Back Pain Using Different Diagnostic Criteria Type de document : Article Auteurs : Henry Tong Article en page(s) : pp. 990-992 Langues : Anglais (eng) Descripteurs : HE Vinci Electromyographie ; Rééducation et réadaptation ; Sciatique Mots-clés : Electromyography  Radiculopathy  Sciatica  Radiculopathie Résumé : Objective To determine the incremental ability of different needle electromyography diagnostic criteria to detect lumbar radiculopathy. Design Blinded cross-sectional study. Setting University hospital. Participants Subjects aged 55 to 80 years with radiating low back pain (n=48; mean age + SD, 67.9+7.3y) and who were asymptomatic (n=30; mean age + SD, 65.4+8y). Interventions Electrodiagnostic evaluation by a blinded electromyographer. A monopolar needle was used to evaluate 5 leg muscles and the lumbar paraspinal muscles. Main Outcome Measures Presence or absence of radiculopathy using different electrodiagnostic criteria. Results When only positive sharp waves or fibrillations were considered, and at least 2 muscles innervated by the same root level and different peripheral nerves were counted as abnormal, 27.1% (13/48) of participants had positive results for radiculopathy. When at least 30% motor unit action potential changes in the limb muscles were also considered, participants with positive results increased to 45.8% (22/48), which was significant when compared with the first criterion (P=.002). When the mini-paraspinal mapping (MiniPM) test as well as at least a 30% motor unit cutoff was used, participants with positive results increased to 50% (24/48), which was significant when compared with the first criterion (P=.001). Conclusions In addition to the presence of positive sharp waves or fibrillations, considering greater than or equal to 30% motor unit action unit potential changes as well as the MiniPM score maintains good specificity and improves the ability of the needle electromyography study to detect lumbar radiculopathy in subjects with radiating low back pain.

Optimal Normalization Tests for Muscle Activation of the Levator Scapulae, Pectoralis Minor, and Rhomboid Major: An Electromyography Study Using Maximum Voluntary Isometric Contractions / Birgit Castelein in Archives of Physical Medicine and Rehabilitation, 2015/10 (2015)  

[article]  inArchives of Physical Medicine and Rehabilitation > 2015/10 (2015) . - pp. 1820–1827 Titre : Optimal Normalization Tests for Muscle Activation of the Levator Scapulae, Pectoralis Minor, and Rhomboid Major: An Electromyography Study Using Maximum Voluntary Isometric Contractions Type de document : Article Auteurs : Birgit Castelein ; Barbara Cagnie ; Thierry Parlevliet Article en page(s) : pp. 1820–1827 Langues : Anglais (eng) Descripteurs : HE Vinci Electromyographie ; Epaule ; Rééducation et réadaptation Mots-clés : Electromyography  Shoulder Résumé : Objective To identify maximum voluntary isometric contraction (MVIC) test positions for the deeper-lying scapulothoracic muscles (ie, levator scapulae, pectoralis minor, rhomboid major), and to provide a standard set of a limited number of test positions that generate an MVIC in all scapulothoracic muscles. Design Cross-sectional study. Setting Physical and rehabilitation medicine department. Participants Healthy subjects (N=21). Interventions Not applicable. Main Outcome Measures Mean peak electromyographic activity from levator scapulae, pectoralis minor, and rhomboid major (investigated with fine-wire electromyography) and from upper trapezius, middle trapezius, lower trapezius, and serratus anterior (investigated with surface electromyography) during the performance of 12 different MVICs. Results The results indicated that various test positions generated similar high mean electromyographic activity and that no single test generated maximum activity for a specific muscle in all subjects. The results of this study support using a series of test positions for normalization procedures rather than a single exercise to increase the likelihood of recruiting the highest activity in the scapulothoracic muscles. Conclusions A standard set of 5 test positions was identified as being sufficient for generating an MVIC of all scapulothoracic muscles: seated T, seated U 135°, prone T–thumbs up, prone V–thumbs up, and supine V–thumbs up. A standard set of test positions for normalization of scapulothoracic electromyographic data that also incorporates the levator scapulae, pectoralis minor, and rhomboid major muscles is 1 step toward a more comprehensive understanding of normal and abnormal muscle function of these muscles and will help to standardize the presentation of scapulothoracic electromyographic muscle activity.
