Abstract Objectives The aim of this experiment was to detect pressure pain threshold (PPT) differences on intra-oral palpation of the lateral pterygoid muscle (LPM) between subjects diagnosed with temporomandibular disorders (TMD) and controls. Methods Thirty-one consecutive female TMD patients and 31 age and gender matched controls underwent palpation of the LPM using an algometer made with a queue-tip connected to a digital scale, and PPT was measured. Results Mean PPTs of the right and left LPM of the controls were respectively 191g (49KPa) and 200g (51KPa), and mean PPTs of the right and left LPM of TMD patients were respectively 245g (62KPa) and 256g (63KPa). ANOVA between the four PPT measurements showed significant difference only between the PPT readings of the right LPM of the controls and the left LPM of the patients (p<0.05). Conclusions The findings of this study suggest that PPT measured by means of the described algometer is not decreased in TMD patients as compared to control subjects.

Introduction: Given the intimate connection of the temporomandibular joint in the cervical region and its functions of chewing, speech and swallowing, patients with temporomandibular disorders (TMD) have most painful condition in stomathognatic muscles. Objective: Check for differences in pressure pain threshold of the masseter (MS), temporalis (TM), upper trapezius (UT) and sternocleidomastoid (SCM) muscles in different types of TMD. Method: Participated in the research 97 subjects, classified according to “The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD)”: myofascial pain (TMD IA), myofascial pain with limited opening (TMD IB), disc displacement with reduction (TMD IIA), disc displacement without reduction and with limited opening (TMD IIB), disc displacement without reduction and without limited opening (TMD IIC). For measurement of the pressure pain threshold (PPT) was used the pressure algometry program (Kratos) of the TM, MS, UT and SCM muscles. For statistical analysis was used the Graphpad Instat program with the Kruskal-Wallis test. Results: The sample consisted of 67 women and 30 men with an average age of 22.09 ± 5.45 years. Of these subjects, 40 were classified as “with TMD”, 57 as “without TMD”, 34 as “TMD IA”, 16 as “TMD IB”, 14 as “TMD IIA” and nobody as “TMD IIB” and “TMD IIC”. The MS, TM and UT muscles showed decreased threshold in myogenic groups of TMD with relation to the group without TMD. Only the masseter muscle showed statistical significance when compared to the myogenic groups with each other, demonstrating that the IB group has lower PPT. Individuals with TMD IB showed lower PPT of MS, TM and UT muscles when compared to TMD IIA. Conclusion: There is a significant difference comparing the PTT of MS, TM and UT muscles of myofascial pain subgroup to the subgroup without TMD. There were differences between the groups myogenic in PPT of MS. TMD IB showed lower threshold in TMD IB group than in TMD IIA group. Controversially, it was not observed when comparing the SCM muscle and disc displacement subgroup with the subgroup without TMD.

Background: In patients with neuromuscular disorder, only little data of myalgia frequency and characterization exists. To date, only a weak correlation between pain intensity and pressure pain threshold has been found, and it remains enigmatic whether high pain intensity levels are equivalent to high pain sensitivity levels in neuromuscular disorders. Methods: 30 sequential patients with suspected neuromuscular disorder and myalgia were analyzed with regard to myalgia characteristics and clinical findings, including symptoms of depression and anxiety and pain- threshold. Results: A neuromuscular disorder was diagnosed in 14/30 patients. Muscular pain fasciculation syndrome (MPFS) without evidence for myopathy or myositis was diagnosed in 10/30 patients and 6/30 patients were diagnosed with pure myalgia without evidence for a neuromuscular disorder (e.g., myopathy, myositis, MPFS, polymyalgia rheumatica). Highest median pain scores were found in patients with pure myalgia and polymyalgia rheumatica. Pressure pain threshold measurement showed a significant difference between patients and controls in the biceps brachii muscle. Conclusion: Only a weak correlation between pain intensity and pressure pain threshold has been suggested, which is concordant with our results. The hypothesis that high pain intensity levels are equivalent to high pain sensitivity levels was not demonstrated.

ABSTRACT Objective:  To assess lateral differences between ossification events and stages of bone development in the hands and wrists utilizing Fishman's skeletal maturation indicators (SMIs). Materials and Methods:  The skeletal ages of 125 subjects, aged 8 to 20 years, were determined with left and right hand-wrist radiographs using Fishman's SMI assessment. Each subject was also given the Edinburgh Handedness Questionnaire to assess handedness. The skeletal ages of both hand-wrist radiographs were analyzed against each other, handedness, chronologic age, and gender. Results:  There were no significant differences overall in right and left SMI scores (P  =  .70); 79% of all patients showed no difference in right and left SMI scores, regardless of handedness, gender, or age. However, when patients were categorized based on clinical levels of SMI score for the right hand-wrist, there was a significant difference (P  =  .01) between the SMI 1-3 group and the SMI 11 group. Subjects in the SMI 1-3 group were more likely to show a left &gt; right SMI score, while subjects in the SMI 11 group were likely to show a right &gt; left SMI score. Conclusion:  Although no significant overall lateral differences in SMI scores were noted, it may be advisable to obtain a left hand-wrist radiograph and/or additional diagnostic information to estimate completion of growth in young surgical patients.

Background/aims:To test whether patients with Parkinson’s disease (PD) have an altered sensory perception in response to painful and nonpainful stimuli and if the PD medications can influence the responses.Methods:PD patients (12) and healthy subjects (12) were recruited. Sensory perception was examined in forearms, low back, and hands by light brush, pinprick, cold pressure test (CPT), and pressure algometry.Results:A significant difference was found in PD patients in response to brush (p<0.05) and pinprick (p<0.001). Lower back and forearms were found to be more sensitive. Tolerance time in CPT was shorter in PD patients (p=0.016). Pressure pain threshold (PPT) before (p=0.011) and after (p=0.050) the CPT showed a higher sensitivity in the patients regardless of the site. No association was found between the sensory perception and the medications.Conclusion:PD patients demonstrated an altered perception to touch and pain stimuli with a general increased in pain intensity and independent of the PD medications.

Abstract Introduction. Pathological muscle tone can cause changes in the facial skeleton, including tension headaches, tinnitus, temporomandibular joint dysfunctions. The complexity of pathologies and their spectrum may also indicate changes beyond the facial skeleton. The aim of the study was to determine the possible correlation between the pressure pain threshold of the trapezius muscle and the bioelectrical tension on the masticatory muscles. Aim. The aim of the study was to determine the possible correlation between the pressure pain threshold of the trapezius muscle and the bioelectric tension on the masticatory muscles. Material and methods. The number of 36 women applied for the study. They were all examined using an algometer within a trapezius muscle to determine the pressure pain threshold. The electromyographic study was carried out in accordance with the SENIAM guidelines. The resting activity of selected masticatory muscles (temporal and masseter) was recorded for 10 sec. The study involved an 8-channel BioEMG IIITM surface electromyography apparatus with BioPak Measurement System (BioResearch Associates, Inc. Milwaukee, WI, USA). Statistical analysis was carried out using the r-Pearson test. The level of significance was set at 5%. Results. After comparing the bioelectric tension of the masticatory muscles and the pressure pain threshold, left-sided correlation was observed (p<0.05). Both in the right-hand and general comparison, the results did not reach the required level of statistical significance (p>0.05). Conclusions. The pressure pain threshold seems to be linked to the bioelectrical muscle tone of the masticatory muscles. To confirm this observation, further research into a larger and more diverse group of participants is recommended.

The purpose of the present study was to investigate the changes in plantar foot force distribution (i.e., the percentage of force and force distribution under the rearfoot and forefoot) and plantar pressure pain sensitivity maps in professional futsal players after long-term low-dye taping (LDT). The subjects (n = 25) were male futsal players (age 23.03 ± 1.15 years). During the experiment, a nonelastic tape was applied on the plantar foot surface according to the standards of LDP. The experimental protocol consisted of a 3-day cycle during which the plantar foot force distribution (FFD) and plantar pressure pain threshold (PPT) were measured: (1) before the tape was applied, (2) 24 h after application, and (3) 72 h after application. The results revealed a significant decrease in the force distribution under the rearfoot (p ≤ 0.001) and forefoot (p ≤ 0.001) on the right and left sides. Moreover, the results showed an increase in the plantar pressure pain threshold in all regions of the foot (p ≤ 0.001). The results of this study suggest that plantar fascial taping can be an effective method for normalizing the force distribution on the foot and reducing the plantar pain threshold. The findings provide useful information regarding the prevention of and physical therapy of lower extremity injuries in soccer and futsal.

The aim of this study is to describe the short-term effects of manual lymph drainage (MLD) isolated in supraclavicular area in healthy subjects. A 4-week cross-sectional, double-blinded randomized clinical trial was conducted. Participants: 24 healthy participants between 18 and 30 years old were recruited from Universidad Europea de Madrid from December 2018 to September 2019. A total of four groups were studied: control, placebo, Vodder, and Godoy. The order of the interventions was randomized. Resting Heart Rate and Oxygen Saturation, blood pressure, pressure pain threshold of trapezius muscle, respiratory rate, range of active cervical movements were measured before and after every intervention. All the participants fulfilled four different interventions with a one-week-wash-out period. No statistically significant differences were found between groups in descriptive data; neither in saturation of oxygen, diastolic blood pressure and cervical range of motion. Significant differences were found in favor of Vodder (p = 0.026) in heart rate diminution and in cardiac-rate-reduction. A significant difference in respiratory rate diminution is found in favor of the Godoy group in comparison with the control group (p = 0.020). A significant difference is found in favor of the Godoy group in systolic blood pressure decrease (p = 0.015) even in pressure pain threshold (p < 0.05). MLD decreases systolic blood pressure in healthy participants. However, it does not produce any changes in other physiologic outcomes maintaining physiologic values, which may suggest the safety of the technique in patients suffering from other pathologies.

OBJECTIVE: To evaluate the number of tender points, pressure pain threshold and presence of fibromyalgia among women with or without dyspareunia.METHODS: The present cross-sectional study included 40 patients with dyspareunia and 30 healthy controls. The participants were asked if they had engaged in sexual intercourse during the previous four weeks, and dyspareunia was rated from 0 to 3 based on the Marinoff Dyspareunia Scale. A pressure algometer (dolorimeter) was used to measure the pressure pain threshold. Fibromyalgia was diagnosed based on the 1990 American College of Rheumatology criteria. The depression status of the participants was assessed using the Beck Depression Inventory.RESULTS: No statistically significant difference was found with regard to age, body mass index, habits (alcohol use and smoking), educational status and occupational status between the two groups. Total myalgic score, total control score and tender point mean pain threshold were significantly lower in the group with dyspareunia. The number of tender points was significantly higher in patients with dyspareunia. The mean Beck Depression Inventory score was 14.7 ±8.4 in the dyspareunia group compared with 11.2 ±7.1 in the control group. Five (12.5%) of the patients with dyspareunia were diagnosed with fibromyalgia, whereas no patients in the control group were diagnosed with fibromyalgia. There was no significant difference between the two groups with regard to the presence of fibromyalgia.CONCLUSION: The finding of lower pressure pain thresholds and a higher number of tender points among patients with dyspareunia suggests that these patients may have increased generalized pain thresholds. Additional studies involving a larger number of patients are required to investigate the presence of central mechanisms in the pathogenesis of dyspareunia.

AbstractBackground and purposeThe psychophysiological responses to and modulation of pressure pain stimulation are relatively new areas of investigation. The aims of the present study were to characterize subjective and cardiovascular (CV) responses to pressure pain stimulation, and to examine the relationship between CV responding and pain pressure pain sensitivity.MethodsThirty-nine pain-free, normotensive women were included in the study and tested during the follicular phase of their menstrual cycles. Pain threshold and tolerance were recorded at the right masseter muscle and the sternum, and visual analogue scales (VAS) were used to rate both pain intensity (the sensory dimension) and discomfort (the affective dimension). Mean arterial pressure (MAP), heart rate (HR), and facial and digital skin blood flux (SBF) were registered continuously.ResultsThe pain threshold and tolerance were significantly higher at the sternum compared with the masseter, but the level of affective distress was higher at the masseter tolerance point. No associations emerged between pressure pain threshold and tolerance stimulation levels, and the corresponding VAS ratings. Pressure pain stimulation of the masseter induced significant increases in MAP, HR, and a decrease in digital SBF. During sternum pressure stimulation a significant change in HR and digital SBF was observed. There were no significant correlations between CV responding and pressure pain sensitivity.ConclusionHealthy women seem to display higher pressure pain sensitivity at the masseter region relative to the sternum. Pressure pain stimulation was associated with significant changes in MAP, HR, and SBF, but was not modulated by CV responses. The validity of these findings is strengthened by our control for menstrual cycle events, weekend-related changes in physiology, and CV changes during pain stimulation.ImplicationsThis study extends previous reports of SBF sensitivity to electrocutaneous pain into the field of pressure stimulation. Moreover, this study suggests that the often demonstrated association between high BP and low pain sensitivity may not apply to pressure pain specifically. Alternatively, this finding adds to the literature of gender differences in the relationship between CV responding and acute pain sensitivity in general.
