Needle-Electromyography Findings of Trigger Points in Neck-Shoulder Area Before and After Injection Treatment

Active myofascial trigger points (MTrPs) in masticatory muscles are associated with a reduced range of motion and muscle weakness within the stomatognathic system. However, it is hard to identify the most effective treatment technique for disorders associated with MTrPs. The objective of this study was to analyze the acute effect of the compression technique (CT) on active maximal mouth opening (MMO) and electromyographic activity of the masseter (MM) and temporalis anterior (TA) muscles in subjects with active myofascial trigger points in the MM muscles. The study group comprised 26 women (mean age 22 ± 2) with bilateral active myofascial trigger points (MTrPs) in the MM. The control group comprised 26 healthy women (mean age 22 ± 1) without the presence of MTrPs in the MM. Masticatory muscle activity was recorded in two conditions (during resting mandibular position and maximum voluntary clenching) before and after the application of the CT to the MTrPs in MM. After the CT application, a significant decrease in resting activity (3.09 μV vs. 2.37 μV, p = 0.006) and a significant increase in clenching activity (110.20 μV vs. 139.06 μV, p = 0.014) within the MM muscles were observed in the study group, which was not observed within TA muscles. Controls showed significantly higher active MMO values compared to the study group before CT (50.42 mm vs. 46.31 mm, p = 0.024). The differences between the study group after CT and controls, as well as among the study group before and after CT did not reach the assumed level of significance in terms of active MMO. The compression technique appears to be effective in the improvement of the active maximal mouth opening and gives significant acute effects on bioelectric masticatory muscle activity. Therefore, CT seems to be effective in MTrPs rehabilitation within the stomatognathic system.

✓ This paper presents a complete method for performing trigeminal thermorhizotomy, guided by neurophysiological data, to relieve tic douloureux. The method involves the use of trigeminal evoked potentials (TEPs) produced by stimulation of the supraorbital, infraorbital, and mental nerves and recorded from electrodes at both the scalp and the trigeminal nerve. To perform the thermorhizotomy, a cannula is modified to produce a concentric bipolar electrode that is suitable for both recording and lesion making. The operating procedure is divided into five steps: Step 1, recording of baseline scalp TEPs from the derivation of the cervical vertex to C-7 to ensure that all stimulating electrodes are correctly placed; Step 2, recording of TEPs from the trigeminal electrode after stimulation of the peripheral nerve trunks to ascertain the electrode's position relative to the root bundles; Step 3, fine positioning of the trigeminal electrode by recording the root activity evoked by stimulation of cutaneous trigger points or of the most painful areas; Step 4, assessing the position of the trigeminal electrode relative to the motor root by stimulating the nerve via the electrode and observing the masseter motor responses; and Step 5, recording scalp TEPs immediately before and after each thermolesion. Thermolesions are made until the scalp-recorded wave W2 decreases its amplitude by 20% to 50% of the original value or until it is delayed by 0.30 msec. This procedure has the potential to enable extremely precise monitoring of the position of the trigeminal electrode relative to the activated fibers and provides very effective monitoring of the extent of the lesion. The authors have performed this procedure with very satisfactory results in 30 patients with trigeminal neuralgia in the second branch.

The purpose of this study is to evaluate the effectiveness of radial shock waves in myofascial upper trapezius syndrome following the global treatment scheme of key trigger points. Materials and methods 26 patients treated with rESWT (Radial shock wave therapy) after a global postural and myofascial assessment of the patient and the identification of the key trigger points. At the end of the treatment each subject was re-evaluated through the Numerical Rating Scale - NRS and through the examination with Electronic Baropodometer. In this study, we compared the values of NRS and the values of postural biometrics before and after 2 sessions of rESWT, and a statistically significant difference (P <0.05) in all measurements emerged in the values measured with NRS. In the static percentage load, a statistically significant reduction in the percentage load differences (right / left) (P <0.05) was observed in all three evaluation moments (T0, T1, T2). The percentage and statistically significant improvement (P <0.05) were recorded at time T2 in the surface of the ellipse. Greater control of balance and greater awareness of the base of support was found in the calculation of the sway path, in particular with closed eyes. Based on this experience, the use of radial shock waves in pathologies related to myofascial pain with postural implications would be desirable.

Abstract Background: The myofascial trigger points (MTPs) may be associated with in shoulder dysfunction.Objective: To evaluate the immediate effect of ischemic compression therapy (ICT) and to verify the effect of the evaluation protocol on MTPs, pain, mobility and strength of shoulder.Methods: 15 individuals were assessed for the amount of MTPs, pressure pain threshold (PPT), range of motion (ROM), isometric strength of shoulder muscles and pain in performing these tests. The evaluations took place 48 hours before the ICT, immediately before, and after the ICT.Results: There was a reduction in the total amount of MTPs (p<0.01; Cliff’s d=0.24-0.35) and an increase in the PPT in the middle deltoid muscle (p=0.03) in the comparisons pre and post treatment, while there was no difference in ROMs and strength measures (p>0.05). The pain was less during the sagittal elevation ROM (p<0.01; d=0.80) and internal rotation (p=0.05; d=0.57), and during the performance of strength in arm elevation and external rotation (p=0.01; d=0.72 and d=0.68). There was generally no difference in the variables assessed between baseline and pre-treatment (p>0.06).Conclusion: The ICT immediately reduced the amount of MTPs and pain during mobility and strength. The evaluation protocol did not influence the studied variables.Trial registration: ReBEC (RBR-3DDG2K).

Eyes Open

The aims of this paper was to determine the effect of self-myofascial release (SMFR) on postural stability and to analyze if it can influence migraine condition. Twenty-five subjects (age 49.7± 12.5) affected by migraine were enrolled. Assessments included a stabilometric analysis in order to evaluate balance and plantar support, with eyes open (OE) and closed (CE); cervical ROM measurement; evaluation of upper limb strength through handgrip. All the analysis were carried out before and after the administration of a single SMFR protocol, using medium density small balls laid in the three most painful trigger points in migraine patients: trapezius, sternocleidomastoids and suboccipital muscles. Performing a T test for paired samples, there was a significant increase in two ranges of the stabilometric analysis: ellipse surface, both with open and closed eyes (p value EO = 0.05; p value EC = 0.04) and length of the sway path, but just with closed eyes (p value = 0.05). SMFR might have a positive impact on postural stability in subjects with migraine. Further investigation should be conducted to confirm the hypothesis.

Nodular Appearance

AbstractA myofascial trigger point (MTrP) is a hyperirritable area of a skeletal muscle, of nodular appearance on palpation and located in a taut band. One of the techniques for the treatment of MTrP is dry needling (DN). The aim of the present work was to determine whether treatment with DN is effective in terms of pain relief and improvement of muscle weakness. For this purpose, differences in the Visual Analog Scale (VAS) and the Brzycki Test were observed before and after treatment of an active MTrP of the rectus femoris. In total, 5 patients received the treatment, of which 80% showed an improvement in pain and an increase in submaximal strength. Although it is not possible to establish a causal relationship, the results appear consistent with our hypothesis that DN is able to generally improve the symptoms of pain and weakness that appeared in patients.
