MyofAPPcial: Construct validity of a novel technological aid for improving clinical reasoning in the management of myofascial pain syndrome.

BACKGROUND: Physiotherapists encounter challenges in diagnosing myofascial trigger points (MTrPs), which are crucial for managing myofascial pain but difficult due to their complex referred pain patterns. We aimed to assess if an interactive software (MyofAPPcial) can enhance the ability of physical therapists specialized in musculoskeletal disorders (as clinicians and as researchers and educators) to identify referred pain patterns associated with specific MTrPs and to explore their opinion about incorporating this technology regularly into their professional setting. METHODS: After developing the app, a descriptive cross-sectional survey study was conducted. Participants were asked about their demographic characteristics, professional experience, two knowledge tests (first without and later with MyofAPPcial support) and the 18-item mHealth app usability questionnaire. RESULTS: Fifty-nine participants completed the survey (47.5% clinicians and 62.5% researchers/educators). Groups were comparable in terms of age, gender and professional experience (p > .05). However, clinicians coursed shorter specific MPS trainings (p = .007) and handle more cases a week (p < .001). In the first knowledge test, participants in both the groups were more accurate in identifying pain maps of highly prevalent MTrPs than those with a moderate or low prevalence (p < .001), with no differences between the groups for individual items (all, p > .05) nor the total score (p > .05). In the second knowledge test, perfect scores were obtained for all items in both the groups. Finally, MyofAPPcial scored high satisfaction and app usefulness, with no difference between clinicians and researchers/educators (except greater convenience of use for researchers/educators p = .02). CONCLUSIONS: MyofAPPcial enhances physiotherapists' ability to accurately identify MTrPs, with a good acceptation among clinicians and researchers/educators.

The effect of physical therapy integrated with pharmacotherapy on tension-type headache and migraine in children and adolescents.

BACKGROUND: Tension-type headache (TTH) and migraine are prevalent neurological conditions in children and adolescents that significantly impact activity of daily living (ADL) and quality of life (QOL). Although physical therapy targeting cervical myofascial trigger points (MTrPs) on TTH and migraine has been extensively studied in adults, the efficacy in pediatric patients remains unexplored. The aim of this study is to reveal the effect of physical therapy integrated with pharmacotherapy on TTH and migraine in children and adolescents. METHODS: We conducted a prospective, observational cohort study recruiting consecutive patients aged 6 to 18 years with TTH and migraine with cervical MTrPs. They were classified into 4 types of headaches: frequent episodic TTH (FRTTH), chronic TTH (CTTH), episodic migraine (EM) and chronic migraine (CM). The once-weekly 40-minutes physical therapy session integrated with pharmacotherapy (integrated physical therapy) was continued until the treatment goals (headache days per week less than 2 days, headache impact test-6 (HIT-6) score to below of 50, and the ability to attend school daily) was achieved. Multifaceted assessments including headache frequency (headache days per week), headache intensity using the Visual Analogue Scale (VAS), pain catastrophizing score (PCS), hospital anxiety and depression scale (HADS) score, HIT-6 scores, and EuroQol 5 dimensions 5-level questionnaire (EQ-5D-5 L) scores, were conducted to evaluate the treatment effects. RESULTS: 161 patients were enrolled in this study. 106 patients (65.8%) were diagnosed with TTH: 70 (66.8%) with FETHH, 36 (34.0%) with CTTH, and 55 patients (34.2%) were diagnosed with migraine: 43 patients (78.2%) with EM, 12 patients (21.8%) with CM. We observed significant improvements in headache frequency, headache intensity, PCS, HADS score, HIT-6 scores, and EQ-5D-5 L scores before and after the treatment in all 4 types of headaches. The average number of sessions required to achieve the treatment goals was 4 times (weeks) for patients with FETTH and EM, 5.5 for those with CTTH, and 7.5 for those with chronic migraine. CONCLUSION: The integrated physical therapy on pediatric TTH and migraine patients with the cervical MTrPs was significantly effective in reducing headache symptoms and improving ADL and QOL.

Efficacy of Myofascial Release With Transcutaneous Electrical Nerve Stimulation Conductive Glove for Neck Myofascial Syndrome: A Randomized Clinical Trial Study.

OBJECTIVE: The purpose of this study was to assess the efficacy of a myofascial release (MR) protocol applied with a transcutaneous electrical nerve stimulation (TENS) conductive glove. METHODS: Eighty individuals with neck myofascial syndrome were randomly divided into 4 groups: (1) MR protocol with a TENS conductive glove (MR+TENS), (2) MR protocol without TENS (MR), (3) conventional TENS protocol (TENS), and (4) placebo TENS (control). All participants attended 6 sessions over a period of 3 weeks. The following measures were evaluated at baseline, at the third week, and at the 1-month follow-up: Pain with the visual analog scale (VAS pain), upper trapezius pressure pain threshold (PPT) with pressure algometry, cervical range of motion (ROM) with goniometry, and disability with the neck disability index (NDI). A 2-way ANOVA with repeated measurements was applied. RESULTS: Significant changes between the 3 intervention groups and the control group were noted in the VAS and the NDI scores (P < .05) with the MR+TENS group exhibiting the biggest difference. Additionally, MR significantly increased PPT compared to TENS, and even further when applied with the conductive glove (P < .05). Regarding lateral flexion ROM, MR was equally effective either alone or in combination with the glove compared to TENS (P < .05). In contrast, TENS did not appear to affect neck PPT and ROM (P > .05). Finally, no difference between the groups was detected in cervical rotation ROM (P > .05). CONCLUSION: The MR protocol appears to be more effective in dealing with pain, disability, and lateral flexion ROM than conventional TENS. A TENS conductive glove significantly improves the effects of MR, possibly due to the combined mechanical and electrical stimulation of the muscle.

Coincidence between the distribution of myofascial trigger points and the presence of blood vessels in the gastrocnemius muscle: Implications for invasive procedures.

PURPOSE: The gastrocnemius venous system presents different anatomical variants. There have been described four locations of myofascial trigger points (MTrPs) in this muscle. However, no studies have analyzed the coincidence between vessels and MTrPs present in the gastrocnemius. Therefore, the main objective was to study the anatomical variability of the venous system by ultrasound and its coincidence with the location of the MTrPs. METHODS: A total of 100 lower limbs were studied. The gastrocnemius vessels were analyzed one by one by sector (medial, central, and lateral), quantifying the number of vessels, their distribution, and the coincidence with MTrPs. RESULTS: All muscle heads showed at least one vessel per section. A large variability was observed, from one to eight vessels per muscle head, with the most frequent number being three in the gastrocnemius medialis and two in the gastrocnemius lateralis. In all cases, the location of the vessels coincided with the MTrPs. CONCLUSIONS: The proximal gastrocnemius venous pattern is very variable between subjects in number of vessels and distribution, which has made it impossible to define a "safe" approach window for invasive procedures without ultrasound guidance. The coincidence between the clinical location of MTrPs of the gastrocnemius and the presence of vessels is total.

OBJECTIVES: To explore the therapeutic effect of Fu's subcutaneous needling at myofascial trigger points (MTrPs) on pain, lumbar mobility and the quality of life in patients with lumbar disc herniation (LDH), so as to provide clinicians with new ideas and methods in treating LDH. METHODS: One hundred patients with LDH admitted to department of rehabilitation medicine of the affiliated hospital of Chengdu University of Traditional Chinese Medicine from January 2022 to January 2023 were collected as the subjects, and they were randomly divided into an observation group and a control group, 50 cases in each one. In the observation group, the spreading technique of Fu's subcutaneous needling was delivered at MTrP. In the control group, the routine acupuncture was applied to Shenshu (BL23), Weizhong (BL40) and MTrP. The treatment was given 3 times weekly, for 2 weeks in the two groups. The score of visual analogue scale (VAS) was evaluated before treatment, at the moment after the 1st treatment completion and after 2 weeks of treatment, separately, and the inclinometer was adopted to measure the range of motion (ROM) of the lumbar flexion, extension and lateral flexion. The numbers of MTrPs and their distribution were recorded before treatment and after the completion of a 2-week treatment in the two groups. Before treatment and in 4 weeks of follow-up, using SF-36 scale, the score of the quality of life was evaluated. The incidence of adverse effects was recorded. RESULTS: At the moment of the 1st treatment completion and after 2 weeks of treatment, VAS score and ROM of the lumbar region were significantly improved in comparison with those before treatment in the two groups and the improvement was superior in the observation group compared with the control group (P<0.05, P<0.01). After 2 weeks of treatment, the total number of MTrPs and the counts of MTrPs in each muscle zone were reduced when compared with those before treatment (P<0.05). In the observation group, the total number of MTrPs and numbers of MTrPs in the zones of quadratus lumborum, musculi multifidus and musculi iliocostalis lumborum decreased significantly when compared with the control group (P<0.05), while the difference was not significant in the numbers in the zone of musculi glutaeus medius between the two groups. In 4 weeks of follow-up, the scores of SF-36 scale were improved in comparison with those before treatment in each group and the result in the observation was better (P<0.05). No any adverse events occurred during treatment in the two groups. CONCLUSIONS: Fu's subcutaneous needling is effective for reducing the numbers of MTrPs and improving analgesia, ROM of the lumbar region, as well as the long-term quality of life in the patients with LDH.

Effects of Dry Needling on Active Myofascial Trigger Points and Pain Intensity in Tension-Type Headache: A Randomized Controlled Study.

Tension-type headache is the most prevalent type of headache and is commonly associated with myofascial pain syndrome and the presence of active myofascial trigger points. This randomized controlled trial aimed to assess the impact of dry needling on the total number of active trigger points, pain intensity, and perceived clinical change in tension-type headache subjects. Thirty-two subjects were randomly assigned to the control and dry needling groups. The presence of active trigger points in 15 head and neck muscles, the headache intensity, and the perceived clinical change were evaluated. A single dry needling technique was administered at each active trigger point across three sessions. Significant differences were observed in the post-treatment measures favouring the dry needling group, including reductions in the headache intensity scores (p = 0.034) and the total number of active trigger points (p = 0.039). Moreover, significant differences in the perception of clinical change were found between the control and treatment groups (p = 0.000). Dry needling demonstrated positive effects in reducing the number of active trigger points and improving the short-term headache intensity in tension-type headache patients. A single dry needling session applied in the cranio-cervical area resulted in a self-perceived improvement compared to the control subjects.

Effects of acupuncture at myofascial trigger points combined with sling exercise therapy on clinical recovery and cervical spine biomechanics in patients with cervical spondylotic radiculopathy.

OBJECTIVE: This research aimed to ascertain the effects of acupuncture at myofascial trigger points (MTrPs) in combination with sling exercise therapy (SET) on the clinical recovery and cervical spine biomechanics in patients with cervical spondylotic radiculopathy (CRS). METHODS: Eighty patients with CSR were divided into Group A and Group B. Group A was treated with acupuncture at MTrPs, and Group B was treated with acupuncture at MTrPs combined with SET. The cervical spine function, pain level, cervical spine biomechanics and the occurrence of complications were compared between the two groups before and after treatment. RESULTS: After treatment, the Japanese Orthopaedic Association scores, Clinical Assessment Scale for Cervical Spondylosis scores, cervical forward flexion angle, posterior extension angle, left lateral flexion angle, right lateral flexion angle, left lateral rotation angle, and right lateral rotation angle of the Group B were raised, and the Neck Disability index, Visual Analogue Scale scores, and Neck Pain Questionnaire scores were reduced versus those of the Group A. The difference in complication rates between the two groups was not of statistical significance. CONCLUSION: Acupuncture at MTrPs combined with SET promotes functional recovery of the cervical spine, reduces pain, and improves cervical spine biomechanics in patients with CRS.

The relationship between myofascial trigger points sensitivity, cervical postural abnormality, and clinical tension-type headache parameters.

BACKGROUND: Myofascial Trigger Points (MTrPs) play a significant role in the pathogenesis of Tension Type Headache (TTH). Abnormal cranio-cervical posture has been linked to various types of headaches. However, the correlation between MTrPs sensitivity, cervical postural alignment, and clinical measures of headache has not been extensively studied in patients with TTH. OBJECTIVES: To investigate the relationship between MTrPs sensitivity in cervical and pericranial muscles, cervical postural abnormality, and clinical headache parameters in patients with TTH. Furthermore, to investigate the effect of sex on the examined variables and their association with headache type (episodic vs chronic TTH). METHODS: A total of 72 patients with TTH of both sexes were enrolled in this study. Headache frequency and disability as clinical measures of headache, pressure pain threshold (PPT) of bilateral upper trapezius (UT) and suboccipital (SUB) muscles, cervical lordosis angle (CA), and anterior head translation (AHT) were measured. RESULTS: Pericranial MTrPs sensitivity did not demonstrate any correlation with clinical headache parameters or cervical postural abnormality. However, there was a significant correlation between the frequency of headaches and the level of disability (r = 0.32, P < 0.05). In addition, episodic TTH was more prevalent in females who exhibited greater AHT and MTrPs sensitivity of both bilateral UT and right SUB muscles than males. CONCLUSIONS: There was no correlation found between the frequency of headaches and the level of disability with measures of cervical posture alignment or MTrPs sensitivity in individuals with TTH.. Based on findings, Clinicians should consider sex differences when assessing patients with TTH.

Electrical dry needling versus a non-invasive multicomponent intervention in the treatment of myofascial trigger points in patients with chronic low back pain: A randomised clinical trial.

OBJECTIVE: To compare the effects of electrical dry needling with a non-invasive multi-component intervention in patients with chronic low back pain. DESIGN: A randomised single-blind clinical trial. SETTING: Outpatient Physiotherapy Clinic; home. PARTICIPANTS: Sixty-four patients with chronic low back pain aged 30-65 years. INTERVENTIONS: Six-week electrical dry needling on myofascial trigger points, and a non-invasive multicomponent intervention (home exercise programme, stretching and ischemic compression). MAIN MEASURES: Pain (Visual Analogue Scale), disability (Roland-Morris Disability Questionnaire and Oswestry Disability Index), kinesiophobia (Tampa Scale of Kinesiophobia), quality of life and sleep (Short Form 36-item Health Survey and Pittsburgh Sleep Quality Index), isometric endurance of trunk flexor muscles (McQuade test), lumbar mobility in flexion (finger-to-floor distance), and pressure pain threshold (algometer) were assessed at baseline, after 6 weeks, and after 2 months. RESULTS: ANOVA showed statistically significant differences in group-by-time interaction for most pain pressure thresholds of myofascial trigger points (P < 0.05), for disability (Roland-Morris Disability Questionnaire: F = 6.14, P = 0.016; and Oswestry Disability Index: F = 7.36, P = 0.009), for trunk anteflexion (F = 10.03, P = 0.002) and for habitual sleep efficacy (F = 6.65, P = 0.012), use of hypnotics (F = 4.77, P = 0.033) and total score of quality of sleep (F = 8.23, P = 0.006). CONCLUSIONS: In comparison to a non-invasive multicomponent intervention, electrical dry needling has more positive effects on disability, pain intensity, kinesiophobia, and reducing patients' sensitivity to myofascial trigger points pressure, at post-treatment and at 2 months.

Assessment of the effects of transforming growth factor beta1 (TGF-ß1)-Smad2/3 on fibrosis in rat myofascial trigger points using point shear wave elastography.

Background & Aims: Myofascial trigger points (MTrPs) are highly sensitive irritated points within a tense belt of skeletal muscle, and are the main cause of muscle pain and dysfunction. MTrPs can also cause paraesthesia and autonomic nervous dysfunction. Furthermore, long-term and chronic MTrPs can cause muscle atrophy and even disability, seriously affecting the quality of life and mental health of patients, and increasing the social and economic burden. However, to date, there have been few studies on fibrogenesis and changes in MTrPs. Therefore, this study investigated whether transforming growth factor beta1 (TGF-ß1)-Smad2/3 participates in the formation of MTrPs and how it affects fibrosis using point shear wave elastography. Methods: Forty Sprague‒Dawley rats were randomly divided into the MTrPs group and the control group. Blunt injury combined with eccentric exercise was used to establish an MTrPs model. Electromyography (EMG), haematoxylin and eosin (H&E) staining and transmission electron microscopy (TEM) were used to verify the model. The collagen volume fraction was measured by Masson staining, the protein expression of TGF-ß1 and p-Smad2/3 was measured by Western blotting (WB) and immunohistochemistry (IHC), and the shear wave velocity (SWV) was measured by point shear wave elastography. Results: EMG, H&E and TEM examination indicated that the modelling was successful. The collagen volume fraction and the protein expression of TGF-ß1 and p-Smad2/3 were higher in the MTrPs group than in the control group. The SWV of the MTrPs group was also higher than that of the control group. These differences suggest that MTrPs may exhibit fibrosis. The correlations between the collagen volume fraction and SWV and between the collagen volume fraction and TGF-ß1 were positive. Conclusion: Fibrotic conditions may be involved in the formation of MTrPs. Ultrasound point shear wave elastography and assessment of TGF-ß1 and p-Smad2/3 expression can reflect the degree of MTrPs fibrosis to some extent. Further exploration of the important role of TGF-ß1 and Smad2/3 in the pathogenesis of MTrPs will be of great significance for clinical treatment.

Comparative effects of Bowen therapy and tennis ball technique on pain and functional disability in patients with thoracic myofascial pain syndrome.

BACKGROUND: Thoracic myofascial pain syndrome is a clinical problem arising from the muscles and soft tissues of thoracic region, which include the mid and upper back area. Risk factors associated with myofascial pain syndrome are muscle overuse and repetitive strain, poor posture, trauma or injury, emotional and psychological stresses. The management of myofascial pain syndrome (MPS) typically involves a multidimensional approach that focuses on relieving pain, reducing muscle tension, and improving muscle function. Bowen therapy and tennis ball technique are also recommended for treating myofascial pain syndrome. OBJECTIVE: The objective of this study was to compare the effects of Bowen therapy and tennis ball technique on pain and functional disability in patients with thoracic myofascial pain syndrome. METHODS: It was a randomized clinical trial conducted on thirty patients. It was carried out in physiotherapy outpatient department of D.H.Q Hospital, Kasur. Non-probability convenience sampling technique was used. Data collection was done from the patients of thoracic myofascial pain syndrome by using Numeric Pain Rating Scale (NPRS) for pain and Pain Disability Questionnaire (PDQ) for functional disability. Participants were randomly allocated into two groups using computer generated random number method. Group A received Bowen therapy, and group B received tennis ball technique. Outcome measures were measured at baseline, after second week treatment session and after fourth week with three sessions in a week on alternate days. Data analysis was done by using Statistical Package for the Social Sciences (SPSS) version 26. RESULTS: There was significant difference between the mean values of NPRS and PDQ in both groups at baseline, second week and fourth week with p value < 0.05. The results indicated that both treatments were significant but Bowen therapy is more effective treatment than tennis ball technique. Within-group difference calculated with repeated-measure ANOVA indicated that there was significant difference from pre- to post-values of both groups. CONCLUSION: This study concluded that Bowen therapy produced statistically significant and clinically relavant results for all the outcome measures. TRIAL REGISTRATION: (IRCT20190717044238N7).

The immediate effects of deep transverse friction massage, high- power pain threshold ultrasound and whole body vibration on active myofascial trigger points.

BACKGROUND: The most important clinical problem in myofascial pain syndrome (MPS) is trigger points (TrPs). The aim of the present study was to investigate the comparison of immediate effect of deep transverse friction massage (DTFM), high-power pain threshold ultrasound (HPPTUS), and whole body vibration (WBV) on treatment of active myofascial trigger points (MTrPs). MATERIALS AND METHODS: sixty six men with active TrPs of upper trapezius muscle were randomly divided into three equal groups: DTFM, HPPT US, and WBV. Pain intensity based on the Visual Analogue Scale (VAS), pressure pain threshold (PPT) and active contralateral lateral flexion range of motion (CLF ROM) of the neck were evaluated before and immediately after the interventions. RESULTS: The VAS, PPT and the active CLF ROM were substantially improved after intervention in all groups (P < 0.01). When the three groups were compared regarding VAS, participants in the WBV group reported significantly more reduction in pain (P < 0.01). On comparing the interventions, there were no significant differences in PPT values (P > 0.05). The CLF ROM value in HPPTUS and WBV groups have significant increase in comparison to the DTFM group. CONCLUSION: All three interventions can improve neck pain, PPT and ROM in participants with active TrPs in upper trapezius muscle, but due to the fact that the DTFM has more pressure on therapist fingers, and the HPPTUS technique requires proper interaction with the participants, WBV can be used as one of the effective intervention on active MTrPs of upper trapezius.

Ultrastructure of Myofascial Trigger Points of Skeletal Muscles of Rats after Photobiostimulation with Low-Intensity Red Light.

The effectiveness of low-intensity red light on myofascial trigger points in skeletal muscle of mature rats was evaluated by electron microscopy and high-resolution respirometry. The revealed changes in mitochondrial ultrastructure and activity of the respiratory chain enzymes indicate the development of hypoxia in the simulation area. Under the influence of low-intensity red light on myofascial trigger points, a decrease in the number of destructively altered muscle fibers and stimulation of mitochondrial respiration were found. These findings indicate intracellular regeneration and the stimulating effect of low-intensity red light on plastic processes.

Remission of Dowager's hump by manipulative correction of spinal alignment: a case report.

Dowager's hump is described as excessive kyphotic curvature in the thoracic spine with a Cobb angle of more than 40 degrees. This case report presents a 61 years old female office clerk who experienced headaches and neck pain for 3 years that extended into her right shoulder and upper chest. She consulted her primary care physician two months before seeing the chiropractor when the neck pain worsened. A diagnosis of cervicalgia related to osteoarthritis was made based on cervical and thoracic X-ray findings. The patient received non-steroid anti-inflammatory drugs (celecoxib and etoricoxib) and stretching exercises at home. At the onset of chiropractic care, radiographs showed loss of cervical lordosis, narrowing at the C4-5, C5-C6, and C6-7 intervertebral disc space with marginal osteophytes. Based on these findings, a working diagnosis of cervicogenic headache was established. After treatment for 9 months, the patient showed improvement in symptoms and function from cervical curve radiographic change and dextro-convexity of the thoracic spine. Avoiding forward head flexion and maintaining correct posture in daily activities will be key mechanisms to prevent the reoccurrence of Dowager's hump. The improvement of symptoms following chiropractic therapy has been shown to correlate with radiographic markers of spinal realignment.

Stress increases the spontaneous release of ACh and may be involved in the generation and maintenance of myofascial trigger points in mouse.

An increase in spontaneous neurotransmission may be related to myofascial pain. Sympathetic neurons innervate most of the neuromuscular junction sand are involved in the modulation of synaptic transmission. Therefore, a direct action of stress on acetylcholine release is expected. For this reason, this study aims to evaluate the relationship between stress and spontaneous neurotransmission. Five acute stressors (immobilization, forced swimming, food and water deprivation, social isolation and ultrasound) were tested in 6 weeks adult Swiss male mice. Subsequently, these types of stress were combined to generate a model of chronic stress. The study of ACh release was evaluated before and after the application of stress by intracellular recording of spontaneous neurotransmission (mEPPs). In each one of the stressors, an increase in the frequency of mEPPs was obtained immediately after treatment, which remained elevated for 5 days and thereafter returned to control values after a week. With chronic stress, a much higher increase in the frequency of mEPPs was obtained and it was maintained for 15 days. In summary, stress, both in its acute and chronic forms, increased spontaneous neurotransmission significantly. There is a possibility that chronic stress is related with the genesis or maintenance of myofascial pain.

Instrumented assisted soft tissue mobilization vs extracorporeal shock wave therapy in treatment of myofascial pain syndrome.

BACKGROUND: Active myofascial trigger points (TrPs) often occur in the upper region of the upper trapezius (UT) muscle. These TrPs can be a significant source of neck, shoulder, and upper back pain and headaches. These TrPs and their related pain and disability can adversely affect an individual's everyday routine functioning, work-related productivity, and general quality of life. AIM: To investigate the effects of instrument assisted soft tissue mobilization (IASTM) vs extracorporeal shock wave therapy (ESWT) on the TrPs of the UT muscle. METHODS: A randomized, single-blind, comparative clinical study was conducted at the Medical Center of the Egyptian Railway Station in Cairo. Forty patients (28 females and 12 males), aged between 20-years-old and 40-years-old, with active myofascial TrPs in the UT muscle were randomly assigned to two equal groups (A and B). Group A received IASTM, while group B received ESWT. Each group was treated twice weekly for 2 weeks. Both groups received muscle energy technique for the UT muscle. Patients were evaluated twice (pre- and post-treatment) for pain intensity using the visual analogue scale and for pain pressure threshold (PPT) using a pressure algometer. RESULTS: Comparing the pre- and post-treatment mean values for all variables for group A, there were significant differences in pain intensity for TrP1 and TrP2 (P = 0.0001) and PPT for TrP1 (P = 0.0002) and TrP2 (P = 0.0001). Also, for group B, there were significant differences between the pre- and post-treatment pain intensity for TrP1 and TrP2 and PPT for TrP1 and TrP2 (P = 0.0001). There were no significant differences between the two groups in the post-treatment mean values of pain intensity for TrP1 (P = 0.9) and TrP2 (P = 0.76) and PPT for TrP1 (P = 0.09) and for TrP2 (P = 0.91). CONCLUSION: IASTM and ESWT are effective methods for improving pain and PPT in patients with UT muscle TrPs. There is no significant difference between either treatment method.

Efficacy of Dry Needling Versus Transcutaneous Electrical Nerve Stimulation in Patients With Neck Pain Due to Myofascial Trigger Points: A Randomized Controlled Trial.

Introduction Myofascial pain is defined as pain arising primarily in muscles and associated with multiple trigger points. Among the non-pharmacological methods, trigger point injection and electrotherapy are effective methods to treat myofascial pain syndrome. This study compares the effectiveness of dry needling (DN) and transcutaneous electrical nerve stimulation (TENS) in reducing cervical pain intensity and improving cervical range of motion in patients with neck pain due to myofascial trigger points. Methods Fifty patients were enrolled and randomized into two groups. Patients in group A received dry needling, and those in group B received TENS. Patients were evaluated using the Visual Analog Scale (VAS), Neck Disability Index (NDI), and Cervical Range of Motion (CROM) before the treatment and on days 14 and 28 after the treatment. The unpaired t-test was used to evaluate quantitative data, except for VAS, where the Mann-Whitney U test was used. All quantitative variables had a normal distribution with a standard deviation except for pain intensity (VAS), which deviated from the normal distribution. The significance level was set at a P-value=0.05. Results Both DN and TENS groups showed significant improvement in VAS, NDI, and CROM between days 0 and 28 (p=<0.001). The DN group showed greater improvements in pain intensity from day 0 to day 28 (p =<0.001). Between days 0 and 28, there was no discernible difference in NDI changes between the groups (p = 0.157 and p = 0.799, respectively). Mixed results were obtained for CROM, with significant improvement of cervical flexion in the dry needling group (p=<0.008) and significant improvement of cervical rotation to the painful side in the TENS group (<0.001). Conclusion Both dry needling and TENS are effective in reducing pain and improving NDI and CROM in patients with neck pain due to myofascial trigger points. However, as dry needling is more effective in pain reduction, a single session of dry needling is more beneficial and cost-effective as compared to multiple sessions of TENS.

Latent myofascial trigger points injection therapy for adult cough variant asthma: A randomized controlled trial.

Background: Cough variant asthma (CVA) is a chronic inflammatory airway disease characterized by airway hyper-responsiveness (AHR), of which cough is the only symptom. The cough is a result of the contraction of the vocal cords, diaphragm, sternocleidomastoid muscle, and other respiratory related muscles caused by the AHR. Long-term chronic coughing can lead to repetitive contraction and chronic strain of the muscles involved in the head and neck, ultimately contributing to the formation of latent myofascial trigger points (MTrPs). In turn, latent MTrPs can also irritate or compress the nerves around them, triggering cough. The date indicated that latent MTrPs can induce autonomic phenomena and are effective in allergic rhinitis. But their roles in asthma are unclear. In this article, the efficacy and safety of latent MTrPs injection therapy in CVA were investigated. Methods: This randomized controlled trial was conducted with 110 patients. Patients were assigned to the intervention or control group in a 1:1.5 ratio. Intervention group (n = 44): single injection therapy with latent MTrPs. Control group (n = 66): budesonide-formoterol plus montelukast for 8 weeks. During the 36-week follow up period, the recurrence rate at week 36, cough visual analog scale (VAS), ACT (asthma control test)-scores, ACQ5 (asthma control questionnaire)-scores, AQLQ (asthma quality of life questionnaire)-scores, proportion of using rescue medication, and adverse events were evaluated. Results: The recurrence rate at week 36 was lower in the intervention group than in the control group (36 weeks, 5.0 vs. 34.55%, p = 0.001). There were significant differences between groups in change from baseline to 36 weeks in VAS [36 weeks, 1.70 (1.49) vs. 3.18 (2.04), p < 0.001]; ACT-score [36 weeks, 21.38 (2.65) vs. 18.53 (3.00), p < 0.001]; ACQ5-score [36 weeks, 0.85 (0.55) vs. 1.52 (0.62), p < 0.001]; AQLQ-score [36w, 174.40 (18.22) vs. 151.69 (24.04), p < 0.001]; proportion of using rescue medication (36 weeks, 5.0 vs. 29.1%, p = 0.003). Fewer adverse events occurred in the two groups. Conclusion: Latent myofascial trigger points injection therapy provided long-acting, practical, short treatment duration and safety methods for CVA.
