Faculty Opinions recommendation of Is There an Association Between Lumbosacral Radiculopathy and Painful Gluteal Trigger Points?: A Cross-sectional Study.

Introduction: The obesity on the myofascial pain syndrome (MPS) was reduced the pain thresholds, leads todecreasing of physical functioning and quality of life. The obese group was more sensitive to pain due to the proinflammatorycondition. This study aimed to examined the relationship between the Body Mass Index (BMI)and the pain threshold in MPS patients.Methods and Materials: This study was a cross-sectional study, conducted in an outpatient clinic of MedicalRehabilitation Department of Dr. Cipto Mangunkusumo Hospital, Jakarta. The subjects recruited consecutively.The pain intensity was assessed subjectively by the Visual Analogue Scale (VAS) score from 0 to 10. Thenumber of the trigger points (TP) were examined palpation manually. The pain threshold was evaluated by thealgometer (Kg) on the upper trapezius muscles.Results: The study has recruited 30 patients, aged 40,5 (20-54). The BMI was 24.97 ± 3.39 Kg/M2. The VASscore was 6 (5-8). The number of the TP was 5.83 ± 1.74. The pain threshold was 2.48 ± 0.52 Kg/ cm2. Most ofthe subjects have overweight (20%) and obesity (47%). There was no correlation between the BMI with the painintensity (r=-0.076, p=0.689), with the number of trigger points (r=0.256, p=0.171) and with the pain threshold(r=0.189, p=0.316).Conclusions: Therefore the BMI was not related to the pain intensity, the number of trigger points as wellas with the threshold of pain in the MPS patients. However, the number of the TP tends to increase, and thethreshold of pain has the tendency to reduced in the obese subjects.Keywords: Obesity; Myofascial Pain Syndrome; VAS; Pain Threshold

Abstract Objective Trigger points (TrPs) are hypersensitive spots within taut bands of skeletal muscles that elicit referred pain and motor changes. Among the variety of techniques used for treating TrPs, dry needling is one of the most commonly applied interventions. The question of eliciting local twitch responses (LTRs) during TrP dry needling is unclear. Our main aim was to investigate the evolution of the electromyographic (EMG) peak activity of each LTR elicited during dry needling into latent TrPs of the gastrocnemius medialis muscle. Methods Twenty asymptomatic subjects with latent TrPs in the gastrocnemius medialis muscle participated in this cross-sectional study. Changes in EMG signal amplitude (root mean square [RMS]) with superficial EMG were assessed five minutes before, during, and five minutes after dry needling. The peak RMS score of each LTR was calculated (every 0.5 sec). Results Analysis of variance revealed a significant effect (F = 29.069, P <0.001) showing a significant decrease of RMS peak amplitude after each subsequent LTR. Differences were significant (P <0.001) during the first three LTRs, and stable until the end of the procedure. No changes (P =0.958) were found for mean RMS data at rest before (mean = 65.2 mv, 95% confidence interval [CI] = 47.3–83.1) and after (61.0 mv, 95% CI = 42.3–79.7) dry needling. Conclusions We found that, in a series of LTRs elicited during the application of dry needling over latent TrPs in the medial gastrocnemius muscle, the RMS peak amplitude of each subsequent LTR decreased as compared with the initial RMS peak amplitude of previous LTRs. No changes in superficial EMG activity at rest were observed after dry needling of latent TrPs of the gastrocnemius medialis muscle.
