Introduction: Pain in the lumbar spine (L) is a very serious health problem. The appearance of pain in the area of the back muscles with palpable small, sensitive points may indicate the presence of myofascial trigger points. There are many techniques used in the therapy of trigger points, including ischemic compression, which gives a therapeutic effect in the form of biomechanical normalization of muscle tissue restoring the normal functional state of a given muscle. Aim of the study: The aim of the study was to assessment of the influence of intermittent ischemic compression of latent trigger points on changes on the range of motion of the L spine and on myoelectric changes in the back extensor muscle. Material and Methods: The study included 32 students who were subjected to a single technique of intermittent ischemic compression according to Chaitow. The participants of the study performed the Thomayer test before and after the therapy to assess the range of spine mobility. The myoelectric changes in the back extensor muscle were assessed using NORAXON's EMG before and after the treatments following a protocol specifically developed for this purpose. The statistical analysis of the data was calculated using the Statistica 13 program. Results: One-time ischemic intermittent compression of the back extensor muscle statistically significantly increased the range of spine motion. The mean value of the tension of the back extensor muscle at rest after the therapy was reduced, showing statistically significant changes. The myoelectric changes in the back extensor muscle during flexion were not statistically significant Conclusions: The results showed the effectiveness of the ischemic intermittent compression technique in increasing the range of spine mobility after the treatment on the back extensor muscle. Intermittent ischemic compression leads to a decrease in the resting tension of the back extensor muscle, without affecting any significant changes during the flexion movement.

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.

Background: Myofascial trigger points (MTP) are palpable painful nodules in a shortened area of a given muscle. The ischemic compression technique (IC), which consists of pressing the painful nodule until the elimination of tension or pain, has been shown to be an alternative for the treatment of MTP. The objective of this study was to analyze the influence of the IC technique on the level of pain to the palpation and electrical activity of the right upper trapezius (RUT) muscle during the elevation of the shoulder girdle and abduction of the shoulder in subjects with MTP. Methods: The sample consisted of ten subjects with mean age of 25.9 ± 2.68 years, who performed scapula elevation and right shoulder abduction up to 180º before and after the IC technique on the RUT muscle. The pain level was measured before and after the application of the IC technique and the myoelectric activity during the movements. Data analysis and processing were performed using the BIOMEC-SAS software and were presented in percentage values of the maximum voluntary isometric contraction (%MVIC). Statistical analysis were performed using the Wilcoxon test (α<0.05). Results: There was a significant increase in the mean% of activation (p=0.007) and in the peak %MVIC (p=0.005) of the myoelectric activity of the RUT muscle during the elevation movement of the right scapula. There was also a significant difference in the reduction of the level of pain referred to palpation (p=0.004). There were no differences during abduction movements. The calculation of the effect size showed that the IC technique had great influence on the results found in this study. Conclusion: The IC technique is an important resource for pain modulation and alteration of the myoelectric activity in MTP patients and can be used by physiotherapists when indicated.

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).

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.

  Introduction and Aim: The decrease in lumbar spine mobility and hamstring tightness can be caused due to the lack of regular exercise and awkward postures exposed at the workplace due to an individual's occupation. It can be expressed due to the awkward posture during dental practice as well and this can be controlled by doing regular exercises.The aim of the present study is to analyze the association of lumbar spine mobility and hamstring tightness in dental practitioners.   Materials and Methods: The study is conducted in a Private dental college and hospital for the dental practitioners who work for more than 4 hours in a day.  The hamstring tightness is measured using the goniometer and lumbar spine flexibility is measured using an inch tape. The measurements are tabulated and analyzed statistically for the correlation of lumbar spine flexibility with hamstring tightness using the SPSS tool.   Results: The collected data are analyzed statistically using correlation coefficient and the findings concluded that they have a low positive correlation. The mean value of lumbar flexion range is 19.37 cm and mean value of the hamstring tightness is 27.8°, the correlation coefficient r is 0.473. Majority of female participants have increased hamstring tightness with a maximum range of 30° and around 11% of male participants have a restriction range of 25°. Similarly, around 8% of female participants have a lumbar flexion range of around 21cm, However, there is no significant difference between the gender in both the variables with p value equals 0.35 and 0.53 (p > 0.05) respectively.    Conclusion: From the obtained results it can be concluded that there is a low positive correlation between hamstring tightness and the lumbar flexion range.  The findings suggest that the dental practitioners are prone to hamstring tightness which in turn can induce reduced lumbar spine mobility and impacts stress on the lumbar spine leading to low back pain.

Abstract Introduction Therapeutic dry needling (DN) is effective in reducing the discomfort of chronic somatosensory tinnitus in patients with myofascial trigger points (MTP)s. Objective To evaluate the efficacy of DN in chronic somatosensory tinnitus discomfort in patients with MTP. Methods Placebo-controlled paired trial that included 16 patients with a diagnosis of somatosensory chronic tinnitus and with the presence of at least one active or latent MTP. Treatment was performed in two phases: (1) four sessions (one session per week for four consecutive weeks) of placebo DN and (2) four sessions of therapeutic DN with a gap (washout) of 15 days between these phases. Results The Tinnitus Handicap Inventory (THI) variable and its emotional domain had a statistically significant reduction in therapeutic DN when compared with placebo DN (p = 0.024 and p = 0.011, respectively).The tinnitus visual analogic scale (VAS) signaled a reduction in tinnitus discomfort when compared with moments before and after therapeutic DN (p < 0.05). Conclusion The therapeutic DN technique for MTP in patients with chronic tinnitus of somatosensory origin proved effective in reducing symptom discomfort, as measured by the THI (total score) and its emotional domain when compared with placebo DN.

Aims To investigate the effect of microsystem acupuncture on painful temporomandibular disorders (TMD). Methods We retrospectively analysed 887 treatments in 407 TMD-patients (mean age 45±1.5 years), who received microsystem acupuncture (mouth, scalp or fingers) with a focus on oral acupuncture. All patients systematically underwent palpation of specific muscular tender points and their pain rating was assessed on a four-point Likert scale (no pain to strong pain) before and after treatment. In 42 cases, the pain intensity was determined using a visual analogue scale (0–100 mm). As the data were normally distributed, analysis was performed with unpaired t-tests. Results The pterygoid muscles were most painful to palpation, with the lateral pterygoid rated moderate to strong by 76% of patients and the medial pterygoid by 48% of patients. The palpation of microsystem acupuncture points revealed the strongest sensitivity (moderate or strong pain) of the oral retromolar points at the upper jaw (83%). After treatment, the pain intensity of all tender points had significantly decreased (P<0.001). The proportion of moderate to strong pain ratings was below 3% at most tender points. Overall pain intensity of the subjects (n=42) before treatment was 55.5±19.7 mm on the VAS scale and was significantly reduced to 29.6±20.9 mm (P<0.001) post-treatment. Conclusions This analysis suggests microsystem acupuncture could reduce the pain intensity of TMD in the short term. Considering the increased local muscular tenderness, further investigations regarding the key role of myofascial trigger points in the occurrence of TMDs are warranted and could lead to new comprehensive treatment strategies.

BACKGROUND: Prone hip extension (PHE) has been investigated to strengthen the hip joint and back extensor muscles. However, it has not been compared with various PHE exercises in individuals with iliopsoas shortness. OBJECTIVE: This study compared pelvic compensation and hip and back extensor muscle activities in individuals with iliopsoas shortness during prone hip extension (PHE) using the abdominal drawing-in maneuver alone (PHEA) and after iliopsoas stretching (PHEAS). METHODS: Twenty-five individuals with iliopsoas shortness were included in the study. Electromyography was used to investigate bilateral erector spinae (ES) and ipsilateral gluteus maximus (GM), biceps femoris (BF), and semitendinosus (ST) muscles during PHE, PHEA, and PHEAS. Pelvic anterior tilting and rotation angles were measured during each PHE exercise via electromagnetic motion tracking. A modified Thomas test was used to examine the hip extension angle before and after iliopsoas stretching. One-way repeated-measures analysis of variance was used to investigate differences in pelvic anterior tilting and rotation angle and in hip and back extensor muscle activities among PHE, PHEA, and PHEAS. The level of statistical significance was set at α= 0.01. RESULTS: GM muscle activity was significantly greater with PHEAS, compared to PHE and PHEA (p< 0.01). Bilateral ES and ipsilateral BF and ST muscle activities were significantly reduced with PHEAS, compared to PHE and PHEA (p< 0.01). Anterior pelvic tilting and rotation angles were significantly reduced with PHEAS, compared to PHE and PHEA (p< 0.01). CONCLUSIONS: PHEAS is recommended to selectively strengthen GM muscles with minimal BF and ST muscle activities and pelvic compensation in individuals with iliopsoas shortness. The abdominal drawing-in maneuver (ADIM) after iliopsoas stretching is more efficient than ADIM alone during PHE, especially in individuals with iliopsoas shortness.

Objective. To analyse the effect of the manual ischemic compression (IC) on the upper limb motor performance (MP) in patients with LTrPs. Materials and Methods. A quasiexperimental study was performed in twenty subjects allocated to either patients group with LTrPs (PG, n=10) or healthy group with no symptoms (HG, n=10). Subjective pain and linear MP (movement time and Fitts’ Law) were assessed before and after a linear tapping task. Data were analysed with mixed factorial ANOVA for intergroup linear motor performance differences and dependent t-student test for intragroup pain differences. Results. PG had a linear MP lower than the HG before treatment (p < 0.05). After IC, the PG showed a significant decrease of pain (4.07 ± 1.91 p < 0.001). Furthermore, the movement time (15.70 ± 2.05 p < 0.001) and the Fitts’ Law coefficient (0.80 ± 0.53 p < 0.001) were significantly reduced. However, one IC session did not allow the PG to get the same MP than the HG (p < 0.05). Conclusion. The results suggest the IC effectiveness on pain and MP impairment in subjects with LTrPs. However, the MP of these patients is only partially improved after the IC application.
