EFFECTIVENESS OF DRY NEEDLING ON THE LUMBAR PARASPINAL MUSCLE IN PATIENTS WITH MECHANICAL BACK PAIN: A RANDOMIZED CONTROLLED TRIAL

Abstract 
 Objective: The aim of this study was to compare the effect of dry needling and sustained pressure in the lumbar paraspinal trigger points in terms of pain threshold and muscle length.
 Methodology: 50 patients were randomly allocated in experimental and control group having lumbar paraspinal muscle trigger points. Experimental and control groups received dry needling and sustained pressure along with stretching and strengthening exercises. Patients were assessed at 1st pre and 4th post session using Oswestry disability index, paraspinal muscle length, visual analogue scale and pain pressure threshold using algometer.
 Results: Pain pressure threshold and visual analogue scale showed significant results whereas Oswestry disability index and paraspinal muscle length showed no significant results (P>0.01). Analysis within the group showed significant difference from pre to post intervention level (P<0.01) in terms of pain pressure threshold, paraspinal muscle length, Oswestry disability index and visual analogue scale in experimental and control group.
 Conclusion: Pain was improved using dry needling. However, no significant improvement was seen in patient’s disability and lumbar paraspinal muscle length.
 Key words: Dry needling, Oswestry disability index, Paraspinal muscle, Trigger points, Visual analogue scale.

Effects of Dry Needling on Pain in Patients with Knee Osteoarthritis: A Preliminary Study.

Background:Osteoarthritis is one of the most common rheumatological diseases and is also considered as one of the causes of myofascial trigger points (MtrPs). Dry needling (DN) is one of the methods used for the treatment of the MtrPs. The aim of the current study was to investigate the effects of DN on pain in participants with knee osteoarthritis (KOA).Materials and Methods:In this before and after preliminary clinical trial study, patients with mild to moderate KOA were enrolled. In one session, after determining the location of trigger points in quadriceps and gastrocnemius muscles, the patients underwent DN. The pain was evaluated at baseline, by passing 4 days and 1 month from the intervention using the Visual Analog Scale (VAS).Results:Sixteen patients with a mean age of 56.5 (4.53) years old have completed the study and follow-up period. According to the ANOVA analysis, VAS values indicated a significant decrease in pain score at the 4th and 1 month after the intervention compared to baseline (P < 0.001). There was no significant difference between VAS at the 4th day of intervention and also 1 month later of intervention (P = 0.087).Conclusion:The application of one session DN can lead to improvement in pain intensity in participants with mild to moderate KOA.

Effects of Dry Needling on Connectivity of Corticospinal Tract, Spasticity, and Function of Upper Extremity in People with Stroke: Study Protocol for a Randomized Controlled Trial

Spasticity is a common motor disorder in adult stroke patients. Injury to the corticospinal tract (CST) is associated with spasticity. Dry needling (DN) has positive impacts on spasticity reduction and improvement in the range of motion (ROM) in stroke patients. This study aims to investigate the effectiveness of DN on the connectivity of the CST and the level of spasticity in adult stroke patients. This double-blind randomized controlled trial will enroll and randomly assign stroke patients to either the experimental group, for receiving three sessions of DN for the spastic wrist flexors, or the control group, for sham needling. The primary outcome measures will be diffusion tensor imaging and the Modified Modified Ashworth Scale score to assess CST connectivity and wrist flexor spasticity, respectively. The Box and Block Test and standard goniometry are the secondary outcome measures to assess hand dexterity and active and passive wrist ROM, respectively. Measurements will be taken both before and after the intervention. The results of this study will provide important evidence of the effects of DN on CST connectivity, spasticity, and arm function in adult stroke patients. This trial is registered in the Iranian Registry of Clinical Trials (IRCT) (https://www.irct.ir; IRCT20191208045649N1).

Effects of dry needling in gluteus medius muscle in individuals with chronic ankle instability: a randomized single-blinded controlled clinical trial

IntroductionBackground: Lateral ankle sprain (LAS) is the most common musculoskeletal injuries in sport and general population. The goal of the present study was to observe the effectiveness of dry needling (DN) in gluteus medius muscle in patients with chronic ankle instability (CAI).Material and methodsA two-arm (1:1), single-blinded (participants), randomized clinical trial was performed in 40 subjects with chronic ankle instability and were divided in two groups: intervention group who received one session of dry needling in the most hyperalgesic gluteus medius myofascial trigger point (MTrP), (n = 20) and control group (n = 20). Dynamic balance, pain intensity, pain pressure threshold (PPT) and ankle dorsiflexion range of motion (ROM) were assessed at baseline, post-intervention and a 1-week follow up.ResultsThe experimental group reported significant differences with respect to the control group for the anterior and medial dynamic balance (p = .001), PPT -ATL (p = .002) and ankle dorsiflexion ROM (p = .001).ConclusionsThe findings of the present study suggested that the DN in the most hyperalgesic MTrP of the Gmed muscle may increase the anterior and medial dynamic balance, ankle ROM and PPT-ATL at short-term in individuals with CAI. Pain intensity benefits were reported in both groups. Future studies should consider DN as a possible intervention in conjunction with a physical therapy program for individuals with CAI.

Effects of dry needling on function, hypertonia and quality of life in chronic stroke: a randomized clinical trial.

Persons with stroke commonly have impairments associated with a reduction in functionality. Motor impairments are the most prevalent, causing an impact on activities of daily life. The aim of this study was to evaluate the effect of a session of dry needling (DN) applied to the upper extremity muscles on the sensorimotor function, hypertonia, and quality of life of persons with chronic stroke. A randomized, sham-controlled clinical trial was performed. Participants were randomly assigned into an intervention group that received a single session DN in the biceps brachii, brachialis, flexor digitorum superficialis and profundus, extensor digitorum, adductor pollicis and triceps brachii muscles, or into a control group that received the same treatment but with a sham DN intervention. Treatment outcomes included the Fugl-Meyer Assessment Scale for the upper extremity, the Modified Modified Ashworth Scale, and the EuroQol-5D questionnaire. Measurements were carried out before, immediately after, and 14 days after intervention. Twenty-three persons participated in the study. Significant differences between groups were observed after the intervention in the total wrist-hand motor score (p = 0.023) and sensorimotor score (p = 0.022), for hypertonia in the elbow extensors both after treatment (p = 0.002) and at follow-up (p = 0.018), and in quality of life at follow-up (p = 0.030). A single session of DN improved total wrist-hand motor function and total sensorimotor function in persons with chronic stroke immediately after treatment, as well as quality of life 2 weeks after treatment.

Effects of dry needling plus exercise therapy on post-stroke spasticity and motor function: A case report

Background and purposeThe use of dry needling (DN) with other treatments may be more beneficial in managing post-stroke spasticity. We report the effects of DN plus exercise therapy (ET) on wrist flexor spasticity. Patient presentationThe patient was a 45-year-old man with an 8-year history of stroke. The outcome measures included the Modified Modified Ashworth Scale (MMAS), Hmax/Mmax ratio, H-reflex latency, Action Research Arm Test (ARAT), Fugl-Meyer Assessment (FMA), and range of motion (ROM) which were assessed before (T1), after (T2), and after 3-week follow-up (T3). ConclusionThe MMAS was improved at T2 from “3” to “2”. The Hmax/Mmax decreased from 0.77 to 0.53 at T3. The H-reflex latency increased from 15.4 ms to 18.5 ms at T3. The wrist active and passive ROM increased ∼30° and ∼20° at T2, respectively.A 4-session DN plus ET may improve spasticity and ROM. No meaningful improvement was observed in function.

Acute and Short-Term Effects of Dry Needling in Patients with Chronic Nonspecific Low Back Pain and Hamstring Tightness: A Pilot Study.

Background Chronic nonspecific low back pain (LBP) is one of the common health issues. Hamstring tightness contributes to the development of LBP. This study aimed to investigate the acute and short-term effects of deep dry needling (DN) in patients with chronic nonspecific LBP and hamstring muscle tightness. Methods A single-group pretest-posttest clinical study design was followed. The outcome measures were the visual analog scale (VAS), passive knee extension (PKE) test, finger-floor distance (FFD) test, and functional rating index (FRI). Patients underwent one session of deep DN of three points on both hamstring muscles, each point for one minute. Patients were assessed before (T0), immediately after (T1), and one week after DN (T2). The FRI was assessed at T0 and T2. Results Ten women with a mean age of 21.1 years (SD = 1.6) participated in the study. Significant large effect sizes in VAS pain reduction (d = 1.25) and PKE hamstring tightness were obtained (hamstring: right, d = 0.82; left, d = 0.88) at T2. Medium effect sizes were obtained for FFD (d = 0.45) and FRI (d = 0.72) at T2. Conclusion A single session of deep DN improved pain and function and increased hamstring flexibility. This pilot study supports the use of DN in patients with LBP and hamstring tightness; however, future research with a rigorous study design of randomized controlled trial is required to confirm the findings. This trial is registered with IRCT20180511039612N1.

Comparing Between the Effects of Dry Needling and Shock Wave in the Treatment of Trapezius Myofascial Pain

Introduction: Musculoskeletal disorders are important causes of pain. Trigger points are one of the common reasons for myofascial pain. This study aimed to compare a single session of dry needling versus a single session of shock wave therapy on the level of pain and Range of Motion (ROM) in the people with Myofascial Pain Syndrome (MPS) of the upper trapezius muscle. Materials and Methods: Sixteen men with active trigger points of upper trapezius muscle were voluntarily attended in this study. They were randomly assigned into two groups. The patients were under a single session treatment of either dry needling or shock wave therapy. Level of pain (by Visual Analog Scale [VAS]) and active ROM of neck lateral flexion (by goniometer) were evaluated once before the treatment and immediately after the intervention. Results: The VAS scores and the neck ROMs were substantially improved at both groups of study immediately after the treatment (P&lt;0.012). However, there were no significant differences between the two groups of interventions in terms of the VAS and ROM scores (P&gt;0.05). Conclusion: Both dry needling and shock wave therapy can improve neck pain and ROM in patients with active trigger points in the upper trapezius muscle.

Immediate Effect of Dry Needling at Myofascial Trigger Point on Hand Spasticity in Chronic Post-stroke Patients: A Multicenter Randomized Controlled Trial

Background: Hand spasticity after stroke influences the rehabilitation of hand function. Immediate and effective relief of spasticity potentially creates conditions for later rehabilitation training, which has far-reaching significance in the smooth transition of patients to the recovery period.Objective: To evaluate the immediate effect of dry needling (DN) at myofascial trigger point on hand spasticity in stroke patients.Methods: This was a prospective, evaluator blind, multicenter, randomized controlled study. A total of 210 participants were randomly divided into DN group (DN, N = 70), sham dry needling group (SDN, N = 70), and control group (N = 70). Participants in the DN group were treated with DN at myofascial trigger point five times (30 min each time) every week for 4 weeks. Subjects in the SDN group were manipulated the same way as in the DN group, except that the acupuncture site was located in the area adjacent to the myofascial trigger point, which constituted a SDN. Routine rehabilitation treatment was performed for participants in the two groups and in the control group. The primary evaluation index was the immediate effect of hand spasticity relief. Secondary evaluation indicators included the cumulative effect of hand spasticity relief from baseline to week 4, and the changes in flexion angles of the wrist, thumb, and fingers 2–5 in the rest position before, immediately after, and 4 weeks after intervention.Results: The immediate effective rate of spasticity relief (thumb, fingers 2–5, and wrist) of patients with different degrees of spasticity in the DN group was higher than that in the control and SDN groups (thumb, χ2 = 55.833, P < 0.001; fingers 2–5, χ2 = 68.096, P < 0.001; wrist, χ2 = 49.180, P < 0.001) (P < 0.05). The effective rate of spasticity relief from baseline to 4 weeks in the DN group exceeded that in the control group and SDN groups (thumb, χ2 = 8.806, P = 0.012; fingers 2–5, χ2 = 8.087, P = 0.018; and wrist, χ2 = 8.653, P = 0.013) (P < 0.05). No difference in immediate and cumulative effect was found between the control group and SDN group. The change of joints flexion angles in resting position before and after each treatment in the DN group was higher than that in the control and SDN groups (P < 0.05), but it was not significantly different between the control group and SDN group. At 4 weeks, although the change in the DN group was higher than that in the control group and SDN group, this difference was not statistically significant (P > 0.05).Conclusion: Dry needling can relieve varying degrees of hand spasticity instantly in post-stroke.Trial Registration: www.chictr.org.cn, ChiCTR1900022379.

The effectiveness of dry needling on hamstring flexibility: A systematic review

Background: Hamstring injuries are a common problem for athletes, and hamstring tightness has been found to be a contributing factor to these injuries. Dry needling is a growing trend that poses the possibility of increasing flexibility through several mechanisms; however, there is currently no review on all of the studies done concerning the effectiveness of dry needling for improving hamstring flexibility. Purpose: The purpose of this systematic review was to evaluate the effectiveness of dry needling on hamstring flexibility in people with hamstring tightness. Methods: Search terms included dry needling or intramuscular stimulation, flexibility or range of motion or ROM, and hamstring. The databases searched were PubMed, MEDLINE, SPORTDiscus, and Cumulative Index to Nursing and Allied Health Literature (CINAHL.) Results: Ten articles were found from the initial search, and three remained after the removal of duplicates and screening the articles for abstracts and full text. Patients consisted of relatively young individuals with hamstring tightness. All studies used a stretching group for the comparison while interventions consisted of dry needling alone or dry needling with a stretching program. No studies showed a significant difference between dry needling and the control; however, all studies found that flexibility increased from baseline measurements following a dry needling treatment. Discussion: The results indicate that while dry needling may not be a better option than stretching, it could be used as a means for improving hamstring flexibility. Possible factors for the effectiveness of dry needling include increased blood flow and oxygen saturation to the muscle as well as the release of myofascial trigger points. Conclusion: Dry needling was not found to be significantly better than stretching, but poses a possibility as another method for improving hamstring flexibility. KEY WORDS: Hamstrings, Athletes, Flexibility, Tightness, Dry Needling, Stretching.

Effects of Dry Needling on Spinal Reciprocal Inhibition

<h3>Research Objectives</h3> Spinal reciprocal inhibition is an important spinal mechanism of motor control. It is often impaired in persons after stroke, negatively impacting locomotion; at the same time, it changes in response to therapeutic interventions (e.g., FES). An increasing number of physical therapists worldwide have been administering trigger point deep dry needling (DDN) to treat post-stroke spasticity. Yet, currently, effects of DDN on spinal somatosensory processing are not well understood. Thus, to understand neurophysiological mechanisms of DDN, we are investigating the effects of DDN on spinal pathways in persons with and without stroke. <h3>Design</h3> Before and 0, 90 minutes, and 72 hours after DDN of the medial gastrocnemius (MG) at myofascial trigger points, reciprocal inhibition of the soleus, MG and lateral gastrocnemius (LG) was examined while the participant stood and maintained his/her standing posture and triceps muscle activity. Passive ankle range of motion (ROM) was also measured before and after DDN. <h3>Setting</h3> University. <h3>Participants</h3> 11 adults 22-57 years old (median 37.5) without known neurological conditions. <h3>Interventions</h3> Trigger point dry needling to medial gastrocnemius <h3>Main Outcome Measures</h3> Reciprocal inhibition of ongoing muscle activity elicited by common peroneal nerve (CPN) stimulation. ROM. <h3>Results</h3> In the MG and LG, there was no systematic changes in the amount of inhibition across participants or measurement times. Soleus inhibition elicited by suprathreshold CPN stimulation was increased significantly at 0 minute and 72 hours post DDN (p>0.05). Ankle dorsiflexion ROM was increased by 4 deg at 0 minutes and 72 hours post DDN. <h3>Conclusions</h3> DDN alters soleus inhibition, which may partially explain increased ankle ROM post DDN. In order to understand how DDN affects reciprocal inhibition in the stroke-impaired CNS, studies of individuals after stroke are currently underway. <h3>Author(s) Disclosures</h3> The authors have no conflicts of interest to declare.

Effects of Dry Needling in Teres Major Muscle in Elite Handball Athletes. A Randomised Controlled Trial.

Objective: To determine the effects of dry needling (DN) in active myofascial trigger points in the teres major muscle compared to an untreated control group in pain during throwing actions, shoulder range of motion (ROM), strength, and extensibility of the tissues in professional handball (HB) athletes. Methods: A randomised, single-blinded, controlled clinical trial was designed. Thirty HB athletes with shoulder pain were randomly assigned to the DN group (n = 15) or control group (n = 15). The DN group received a single session of ultrasound-guided DN technique in the teres major muscle. The control group received no intervention. Pain intensity during throwing actions (Numeric Pain Rating Score), shoulder ROM (inclinometer), isometric strength (hand-held dynamometer), and extensibility (inclinometer) were measured before and after treatment. Results: DN group showed statistically significant improvements with large effect sizes for pain intensity (p < 0.001; E.S: 1.3), internal rotation ROM (p < 0.001; E.S: 3.0) and extensibility (p < 0.001; E.S: 2.9) compared to the control group. No statistically significant differences were found for isometric strength (p > 0.05). Conclusion: A single session of DN in the teres major muscle was effective for improving pain intensity during throwing actions, internal rotation ROM and extensibility in HB athletes with shoulder pain.

Effects of dry needling on gait and muscle tone in Parkinson's disease: a randomized clinical trial.

Alterations in gait and muscular rigidity are common and disabling in persons with Parkinson's disease (PD). The aim of this study was to determine whether a single dry needling (DN) session can promote changes in gait and muscle tone in the lower extremities as well as in the evolution of the disease in persons with PD. A randomized double-blind clinical trial was designed. Participants were randomly assigned to an intervention group (IG) that received a session of DN over the semitendinosus, medial gastrocnemius, soleus and rectus femoris muscles, or to a control group (CG) that received a session of sham DN in the same muscles. The effects of DN were assessed using the timed up and go test (TUG), 10 meter walk test (10MWT), 6 minute walk test (6MWT) and myotonometry before, immediately after, and 7 days after the intervention. Thirty-three participants were analyzed aged 69.9 ± 7.2 years (mean ± SD; 39% female). There were no significant differences between the IG and CG for any outcomes. Significant differences were observed when comparing the Pre and Follow-up values in the IG for functional mobility of gait in the TUG (p = 0.049), gait speed in the 10MWT (p = 0.041) and muscle tone in the lower extremities by myotonometry (frequency (p = 0.027) and stiffness (p = 0.013)). By comparison, there were no significant within-group differences in the CG. A single session of DN had no measurable benefit compared to a single session of sham DN. Within-group changes in the IG suggested improvements in functional mobility of gait and gait speed, as well as changes in the muscle tone in the lower extremities of PD patients, which could be worthy of further exploration by future research.

Effect of dry needling on lumbar muscle stiffness in patients with low back pain: A double blind, randomized controlled trial using shear wave elastography

ABSTRACT Background Dry needling treatment focuses on restoring normal muscle function in patients with musculoskeletal pain; however, little research has investigated this assertion. Shear wave elastography (SWE) allows quantification of individual muscle function by estimating both resting and contracted muscle stiffness. Objective To compare the effects of dry needling to sham dry needling on lumbar muscle stiffness in individuals with low back pain (LBP) using SWE. Methods Sixty participants with LBP were randomly allocated to receive one session of dry needling or sham dry needling treatment to the lumbar multifidus and erector spinae muscles on the most painful side and spinal level. Stiffness (shear modulus) of the lumbar multifidus and erector spinae muscles was assessed using SWE at rest and during submaximal contraction before treatment, immediately after treatment, and 1 week later. Treatment effects were estimated using linear mixed models. Results After 1 week, resting erector spinae muscle stiffness was lower in individuals who received dry needling than those that received sham dry needling. All other between-groups differences in muscle stiffness were similar, but non-significant. Conclusion Dry needling appears to reduce resting erector spinae muscle following treatment of patients with LBP. Therefore, providers should consider the use of dry needling when patients exhibit aberrant stiffness of the lumbar muscles.

Dry Needling and Management of Trigger Points with Low Back Pain: An Evidence to Practice Review

Low back pain is a common health concern. The development of myofascial trigger points due to low back pain can cause debilitating pain and loss of functional movement in patients. Dry needling is a minimally invasive procedure that has shown to be useful in the treatment of myofascial trigger points when used with other forms of treatment. However, the literature surrounding dry needling and myofascial trigger points in patients with low back pain is lacking. The guiding systematic review and meta-analysis sought to analyze the effectiveness of dry needling for patients with low back pain. The review utilized eight databases for randomized controlled trials and selected 11 of 784 articles for analysis based on inclusion and exclusion criteria. A 6-subgroup meta-analysis was conducted on these studies, and 6 of the 11 studies were found to have high risk of bias. The included studies used both pain measurements and functional measurements including the visual analogue scale (VAS), Oswestry Disability Index (ODI), and the Roland-Morris Disability Questionnaire (RDQ). The studies did not include objective functional measurements. Overall researchers found a clinically meaningful decrease in outcome scores in the short-term, but there were no significant differences in pain or functional outcomes through long-term follow-up. This seems to correlate with the current literature on dry needling and its inflammatory effects on the body, suggesting that dry needling alone does not provide any long-term effect on myofascial trigger points in patients with low back pain. Dry needling should be combined with other treatments and high-quality rehabilitation to provide longer-lasting results and better treatment outcomes for patients with low back pain.

Effects of dry needling of the obliquus capitis inferior on sensorimotor control and cervical mobility in people with neck pain: A double-blind, randomized sham-controlled trial

BackgroundImpairments of sensorimotor control relating to head and eye movement control and postural stability are often present in people with neck pain. The upper cervical spine and particularly the obliquus capitis inferior (OCI) play an important proprioceptive role; and its impairment may alter cervical sensorimotor control. Dry needling (DN) is a valid technique to target the OCI. ObjectivesTo investigate if a single DN session of the OCI muscle improves head and eye movement control-related outcomes, postural stability, and cervical mobility in people with neck pain. MethodsForty people with neck pain were randomly assigned to receive a single session of DN or sham needling of the OCI. Cervical joint position error (JPE), cervical movement sense, standing balance and oculomotor control were examined at baseline, immediately post-intervention, and at one-week follow-up. Active cervical rotation range of motion and the flexion rotation test were used to examine the global and upper cervical rotation mobility, respectively. ResultsLinear mixed-models revealed that the DN group showed a decrease of JPE immediately post-intervention compared to the sham group (mean difference [MD]= -0.93°; 95% confidence interval [CI]: -1.85, -0.02) which was maintained at one-week follow-up (MD= -1.64°; 95%CI: -2.85, -0.43). No effects on standing balance or cervical movement sense were observed in both groups. Upper cervical mobility showed an increase immediately after DN compared to the sham group (MD= 5.14°; 95%CI: 0.77, 9.75) which remained stable at one-week follow-up (MD= 6.98°; 95%CI: 1.31, 12.40). Both group showed an immediate increase in global cervical mobility (MD= -0.14°; 95%CI: -5.29, 4.89). ConclusionThe results from the current study suggest that a single session of DN of the OCI reduces JPE deficits and increases upper cervical mobility in patients with neck pain. Future trials should examine if the addition of this technique to sensorimotor control training add further benefits in the management of neck pain.

Effects of dry needling on mechanical and contractile properties of the upper trapezius with latent myofascial trigger points: A randomized controlled trial

BackgroundLatent trigger point (LTrP) can cause motor dysfunction and disturb normal patterns of motor recruitment. ObjectiveTo analyze the effects of DN in the upper trapezius (UT) LTrP on pain and the mechanical and contractile properties of the muscle. DesignA randomized, double-blinded, parallel-group-trial. MethodsFifty healthy volunteers with LTrPs in the UT were randomly divided into a DN-group (n = 26) and a Sham-DN-group (n = 24) and received one session of DN or placebo treatment. Mechanical and contractile properties of the muscle and pressure pain perception (PPP) were evaluated before treatment and in a 30min, 24 h and 72 h follow-up after treatment. ResultsIn the mechanical properties, the DN-group showed lower values than the Sham-DN-group for dynamic stiffness at 72 h (p = 0.04). The DN-group showed lower values for dynamic stiffness at 72 h from baseline (278.74 ± 38.40 to 261.54 ± 33.64 N/m; p = 0.01) and for tone at 72 h from 30min (16.62 ± 1.27 to 15.88 ± 1.31 Hz; p = 0.01). In the contractile properties, the DN-group showed higher values for maximal radial displacement (Dm) of the muscle belly at 72 h from baseline (5.38 ± 1.67 to 6.13 ± 1.70 mm; p = 0.04), higher values for contraction time at 30min (28.53 ± 8.80 s; p = 0.03) and lower ones at 72 h (24.74 ± 4.36 s; p = 0.04) from baseline (26.97 ± 6.63 s). The DN-group showed a decrease of PPP from baseline to 72 h after treatment (5.16 ± 1.33 to 4.02 ± 0.97 mm; p < 0.01). ConclusionThe application of DN in healthy volunteers over LTrPs in the UT decreased dynamic stiffness, tone and contraction time and increased Dm at 72 h after treatment. Additionally, the PPP showed a decrease at 72 h after needling. ClinicalTrials.govNCT04466813

Comparison of the effectiveness of dry needling with dry cupping at upper trapezius muscle in patients with myofascial trigger points.

Background: Trigger points are palpable nodules or irritable spots present in the skeletal muscles, painful upon pressure. This study is concerned with the pain in the upper Trapezius muscle due to the formation of myofascial trigger points and to make a comparison of the effectiveness of dry needling with dry cupping for treating upper trapezius myofascial trigger points.&#x0D; Methodology: Myofascial trigger points were diagnosed in 30 individuals in the upper trapezius. Subjects were randomized into Group-A (n=15) and Group-B (n=15) using the coin toss method. Patients were evaluated at baseline and after the termination of intervention using the Numeric Pain Rating Scale (NPRS), Neck Disability Index (NDI) and cervical joint range of motions (ROM). Patients from both groups received three sessions of treatment on alternate days in one week.&#x0D; Results: Patients with both interventions resulted in significant improvement of NPRS (p=0.001), NDI (p=0.001), and cervical ranges of motion (p=0.001). However, between groups comparison of outcome measure showed no significant difference in NPRS (p=0.990), NDI (p=0.359), cervical flexion (p=0.457), cervical extension (p=0.382), right cervical lateral flexion (p=0.250), left cervical lateral flexion (p=0.792), right cervical rotation (p=0.336), and left cervical rotation (p=0.242) of motion.&#x0D; Conclusion: The pre-and post-intervention results have concluded that both treatment methods effectively treat myofascial trigger points. There was no significant difference between the two groups for numeric pain rating scale, neck disability index scoring and cervical range of motions.

Effectiveness of Dry Needling in Bothersome Chronic Tinnitus in Patients with Myofascial Trigger Points.

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.
