Effects of different treatments on pain, functional disability, position sense and range of motion in elite bodybuilders with chronic low back pain.

Back pain is one of the major global challenges and is one of the most prevalent musculoskeletal disorders occurring in 80% of people at least once in their lifetime. Therefore, the need to find appropriate treatment methods for this issue is very important. The objective is to examine the short-term and acute effects of a treatment session with dry needling, massage therapy, stretching exercises and Kinesio tape on pain, functional disability, position sense and range of motion in elite bodybuilders with non-specific chronic low back pain. The sample of this quasi-experimental study consisted of 48 bodybuilders with non-specific chronic low back pain (all male, mean age = 25.96 ± 2.18 years; mean weight = 74.45 ± 4.51 kg; mean height = 173.88 ± 3.74 cm; mean BMI = 24.60 ± 0.74 kg/m2) who randomly were placed in 4 dry needling, massage therapy, stretching exercises and Kinesio tape groups. The duration of each intervention was 30 min. The dependent variables in this study included the massage range of motion, position sense tests and visual pain scale that were taken separately from each subject in pretest, posttest (acute effect) and follow-up test (72 h after posttest; short-term effect). The results of a 4 (groups) × 3 (time) the mixed ANOVAs showed that pain in the short-term phase was significantly lower in the dry needling group than in the stretching and massage groups (P < 0.05). Also in the acute effect phase, the flexion range of motion was significantly lower in the dry needling group than in the massage group (P < 0.05). Furthermore, the two groups of stretching and massage exercises showed significantly greater range of motion (P < 0.05). Other comparisons were not significant (P > 0.05). The findings of the study showed that both massage and stretching treatment have higher acute effects, while dry needling treatment was more effective in follow up. On the other hand, these findings show that these treatment methods can have immediate and lasting positive effects in improving the performance in elite bodybuilders with non-specific chronic low back pain.

Effects of transcutaneous electrical nerve stimulation on pain, function, and descending inhibition in people with non-specific chronic low-back pain: a study protocol for a randomized crossover trial.

BACKGROUND: Low back pain (LBP) is a significant public health problem, is very prevalent, and is often characterized by the persistence of symptoms. Transcutaneous electrical nerve stimulation (TENS) may benefit people with chronic LBP because it can activate descending inhibitory pathways and inhibit central excitability. However, previous studies that have investigated the effects of TENS on pain in people with LBP have failed to use proper intensities of current, and the timing of the assessment of pain was not performed during the peak of the analgesic response or functional activities. Therefore, the present study aims to assess the effects of TENS on measures of pain, function, and descending inhibition using the maximal tolerable intensity of TENS in participants with LBP. METHODS/DESIGN: This study will be a randomized crossover trial. The participants for this study will be recruited from various places, including the University of Hartford, physical therapy clinics, and local businesses in the Hartford area, as well as online websites geared towards clinical trial recruitment. A total of 34 participants will receive all three treatments: active TENS, placebo TENS, and no treatment control. The treatment order will be randomized using a website-based randomization tool. For active TENS, a modulating frequency of 2-125 Hz will be applied with a variable pulse duration and maximal tolerable intensity for 30 min. The TENS will be left on for post-treatment testing to assess the effects during its maximally effective period for a total of 50 to 60 min. Furthermore, the intensity may be turned down if muscle twitching is present to ensure blinding of the evaluator. For placebo TENS, the unit will deliver current for 45 s, ramping to 0 in the last 15 s. The primary outcome will be pain intensity at rest and with movement, determined using the numerical pain rating scale. The secondary outcomes will be pressure pain threshold, heat pain threshold, temporal summation of pain, conditioned pain modulation, sit-to-stand test, and repeated trunk flexion. The assessments will be performed immediately before and after treatment. Statistical analysis of the data obtained will consider a significance level of p < 0.05. DISCUSSION: This study will provide evidence concerning the effects and mechanisms of TENS treatment in participants with chronic non-specific low back pain. The outcomes, including pain, function, and descending inhibition, will help us gain a greater understanding of how TENS can be used for these participants.

Treating Lateral Epicondylopathy With Dry Needling and Exercise: A Case Series.

CONTEXT: Lateral epicondylopathy (LE) is a common overuse injury affecting elbow, wrist, and hand function. It is characterized by weakness and pain in the muscles and tendons of the forearm responsible for the extension of your wrist and fingers. Trigger point dry needling is a technique reported to be beneficial in managing pain and dysfunction after LE diagnosis. LE is also commonly treated with conservative treatment, such as joint and soft tissue mobilization, self-care home programs, and anti-inflammatory use. We explored a different dry needling approach consisting of in situ dry needling with electric stimulation combined with targeted therapeutic exercise to treat LE in 3 cases. CASE PRESENTATION: Three patients were referred for dry needling once a week for 6 weeks and home-based exercise therapy for LE. They were clinically evaluated using grip strength, a visual analog scale to assess pain, and Patient-Rated Tennis Elbow Evaluation Test scores. These were measured at 4 time points (weeks 0, 2, 4, and 6). MANAGEMENT AND OUTCOMES: The dry needling intervention incorporated 8 locations in the upper-extremity with 2 electric stimulation channels. The patients had reduced pain as measured by a visual analog scale, increased function as measured by the Patient-Rated Tennis Elbow Evaluation Test, and increased grip strength over 6 weeks. CONCLUSIONS: This case series illustrates the use of dry needling and a home exercise program to provide a favorable outcome in a patient with LE. Patients had an 80% to 100% reduction in pain and similar improvements in function that were significantly beyond the minimum clinically important difference. This dry needling approach is a safe and effective treatment of LE in the short term.

Amyotrophic Lateral Sclerosis and Pain: A Narrative Review from Pain Assessment to Therapy.

Amyotrophic lateral sclerosis (ALS) is the most frequent neurodegenerative disease of the motor system that affects upper and lower motor neurons, leading to progressive muscle weakness, spasticity, atrophy, and respiratory failure, with a life expectancy of 2-5 years after symptom onset. In addition to motor symptoms, patients with ALS have a multitude of nonmotor symptoms; in fact, it is currently considered a multisystem disease. The purpose of our narrative review is to evaluate the different types of pain, the correlation between pain and the disease's stages, the pain assessment tools in ALS patients, and the available therapies focusing above all on the benefits of cannabis use. Pain is an underestimated and undertreated symptom that, in the last few years, has received more attention from research because it has a strong impact on the quality of life of these patients. The prevalence of pain is between 15% and 85% of ALS patients, and the studies on the type and intensity of pain are controversial. The absence of pain assessment tools validated in the ALS population and the dissimilar study designs influence the knowledge of ALS pain and consequently the pharmacological therapy. Several studies suggest that ALS is associated with changes in the endocannabinoid system, and the use of cannabis could slow the disease progression due to its neuroprotective action and act on pain, spasticity, cramps, sialorrhea, and depression. Our research has shown high patients' satisfaction with the use of cannabis for the treatment of spasticity and related pain. However, especially due to the ethical problems and the lack of interest of pharmaceutical companies, further studies are needed to ensure the most appropriate care for ALS patients.

Chloroprocaine 3% Gel as a Novel Ocular Topical Anesthetic: Results from a Multicenter, Randomized Clinical Trial in Patients Undergoing Cataract Surgery.

Purpose: To compare the efficacy and safety of a novel ophthalmic anesthetic, chloroprocaine 3% gel to tetracaine 0.5% eye drops in patients undergoing cataract surgery with phacoemulsification. Methods: This was a prospective, randomized, multicenter, active-controlled, masked-observer, parallel group competitive equivalence study. The study comprised 338 patients having routine cataract extraction by clear corneal phacoemulsification, randomized to receive 3 drops of chloroprocaine gel (n = 166) or tetracaine eye drops (n = 172) before surgery. The primary objective of the study was to assess the equivalence of chloroprocaine gel to tetracaine eye drops as proportion of patients with successful ocular surface anesthesia, without any supplementation just before intraocular lens implantation. Safety measurements were pain, irritation, burning, stinging, photophobia, and foreign body sensation, graded by the patient and objective ocular signs. Results: Equivalence was demonstrated, with a somewhat higher success rate of chloroprocaine gel: 152/166 (92.0%) chloroprocaine versus 153/172 (90.5%) tetracaine patients achieved ocular surface anesthesia with no supplementation. Difference in proportions was 1.5% confidence interval [95% CI: (-3.6 to 6.6)] and 90% CI fell within (-10 to 10). Mean onset of anesthesia was 1.35 ± 0.87 min for chloroprocaine and 1.57 ± 1.85 for tetracaine (P = 0.083). Mean duration of anesthesia was 21.57 ± 12.26 min for chloroprocaine and 22.04 ± 12.58 for tetracaine (P = 0.574). No treatment emergent adverse events related to chloroprocaine were reported and no relevant findings related to local tolerance or vital signs were observed in both arms. Conclusions: Results obtained from the present cataract study demonstrated that chloroprocaine 3% ophthalmic gel is safe and effective, representing a valid alternative in ocular topical anesthesia.

The Effect of Reiki on Pain, Functional Status, and Holistic Well-Being in Patients With Knee Osteoarthritis: A Randomized Controlled Trial.

Knee osteoarthritis (OA) is a chronic degenerative joint disease that causes pain and adversely affects functional status and holistic well-being. This randomized controlled trial investigated the effect of Reiki on pain, functional status, and holistic well-being in patients with knee OA. The sample consisted of 42 patients. The control group received standardized treatment only, whereas the intervention group received face-to-face Reiki (nine positions; 39 minutes) and distance Reiki on two consecutive days in addition to standardized treatment. The Reiki group had lower pain scores than the control group as measured by the Visual Analog Scale (p < .001) and the Western Ontario and McMaster Universities Arthritis Index pain score (p < .001). Those participating in the Reiki group had improved holistic well-being scores specifically for the subscales of Sadness, Perception of Sadness, Spiritual Disruption, Cognitive Awareness, and General mood. Reiki is a safe, noninvasive, and cost-effective alternative treatment technique that has the potential to reduce symptoms of pain and improve holistic well-being in patients with knee OA.

Effect of Warm and Cold Acupressure Applied to the LI4 Acupressure Point on Childbirth Comfort During Labor: A Randomized Controlled Trial.

Context: Labor pain is considered one of the most well-known types of severe pain. For this reason, non-pharmacological methods employed for managing labor pain are necessary to help pregnant women cope with labor pain and increase their childbirth comfort. Objectives: The aim of this study was to determine the effect of cold and warm acupressure applied to the LI4 acupressure point on childbirth comfort in primiparous women during labor. Design: This study was designed as a randomized controlled experimental trial. Setting: The study was conducted between August 2020 and March 2021 at 2 hospitals in northern Turkey offering similar maternity services. Participants: The sample consisted of 129 healthy pregnant women: 44 in the warm acupressure group, 44 in the cold acupressure group and 41 in the control group. Intervention: Participants were randomly assigned to one of the three groups. The researcher applied cold or warm acupressure pouches, respectively, on the women in the 2 experimental groups on the LI4 acupressure point for 10 minutes during the active and transition phases of labor. The application was suspended for 1 hour, and then repeated 3 more times. No acupressure was administered in the control group. Outcome Measures: The Personal Information Form (PIF), Labor Monitoring Form (LMF), Visual Analog Scale (VAS) and Childbirth Comfort Questionnaire (CCQ) were used to gather study data. Results: There was a statistically significant difference between both the intergroup and intra-group pain scores in the experimental and control groups (P < .05) and childbirth comfort scores in the experimental and control groups in terms of groups and timing (P < .05). Conclusion: In this study, both warm and cold acupressure were found to alleviate labor pain. The warm acupressure, in particular, had a more positive effect on childbirth comfort. Thus, warm and cold acupressure can be recommended to relieve labor pain and increase childbirth comfort.

COMPARISON THE EFFICACY OF DRY NEEDLING AND ISCHEMIC COMPRESSION METHODS IN MIYOFASCIAL PAIN SYNDROME: A RANDOMIZED TRIAL.

Myofascial pain syndrome (MPS) is the most common in the musculoskeletal disease. Dry needling techniques and ischemic compression are the most common applications. We aimed to compare the efficacy of dry needling and ischemic compression methods on pain, cervical range of motion and disability in myofascial pain syndrome. This is a randomized, controlled study. 98 patients with MPS were randomly assigned into three groups. Group1 received dry needling (n=33), group 2 (n=33) received ischemic compression and group 3 (n=32) received combined with dry needling and ischemic compression inventions. Additionally, all patients were given neck exercise programs including isotonic, isometric, and stretching. The severity of the pain was measured by visual analog scale (VAS). The pressure pain threshold (PPT) and cervical range of motion (ROM) were also recorded. Disability was assessed by the Neck Pain Disability Scale. All assessments were performed before the treatment and one month and three months after the treatment. There were statistically significant improvements in VAS, PPT, cervical ROM, and disability scores after one and three months in all groups compared to pre-treatment results (p<0.05). After three months of follow-up, statistically significant differences were observed in all parameters between the groups (p<0.05) except cervical ROM (p>0.05). Myofascial pain syndrome in patients with ischemic compression and dry needling effective treatment methods are shown separately in our study to be more effective when used together.

Efficacy of aquatic vs land-based therapy for pain management in women with fibromyalgia: a randomised controlled trial.

OBJECTIVE: To determine the efficacy of two physiotherapeutic interventions - aquatic therapy (AT) and land-based therapy (LBT) - for reducing pain in women with fibromyalgia. DESIGN: Single-blind, randomised controlled, equivalence trial. SETTING: Fibromyalgia, Chronic Fatigue Syndrome and Multiple Chemical Sensitivity Association in A Coruña, Spain. PARTICIPANTS: Forty women with fibromyalgia were assigned at random in a 1:1 manner to two groups: AT (n = 20) and LBT (n = 20). INTERVENTIONS: Two therapeutic exercise programmes, with 60-min sessions, were undertaken three times per week for 12 weeks. Sessions were carried out in groups by a trained physiotherapist. OUTCOME: The primary outcome was pain intensity (visual analogue scale). The secondary outcomes were pressure pain threshold (algometer), quality of life (Revised Fibromyalgia Impact Questionnaire), sleep quality (Pittsburgh Sleep Quality Index), fatigue (Multidimensional Fatigue Inventory) and physical ability (6-Minute Walk Test). Patients were evaluated at baseline, 12 weeks (post-treatment) and 18 weeks (follow-up). The statistical analysis was per-protocol. P < 0.05 was considered to indicate significance. Effect size was calculated. RESULTS: The mean age was 50 [standard deviation (SD) 9] years, with median body mass index of 27 [interquartile range (IQR) 25-30] kg/m2 and median symptom duration of 11 (IQR 6-15) years. No differences were observed between the groups post-treatment, but differences in favour of AT were found in pain intensity [2.7 (IQR 1.5-4.9) vs 5.5 (IQR 3.3-7.6); p= 0.023; large effect, Cohen's d= 0.8; 95% confidence interval (CI) 0.1-1.5] and sleep quality [12.0 (IQR 7.3-15.3) vs 15.0 (IQR 13.0-17.0); p= 0.030; large effect, Cohen's d= 0.8; 95% CI 0.1-1.5] at follow-up. CONCLUSIONS: The results suggest that AT is better than LBT for reducing pain intensity and improving sleep quality after 6 weeks of follow-up. AT may be a good treatment option for women with fibromyalgia. CLINICAL TRIALS REGISTRATION NUMBER: ClinicalTrials.gov NCT02695875 CONTRIBUTION OF THE PAPER.

Treatment of Women With Primary Dysmenorrhea With Manual Therapy and Electrotherapy Techniques: A Systematic Review and Meta-Analysis.

OBJECTIVE: The objective of this study was to evaluate the efficacy of electrotherapy and manual therapy for the treatment of women with primary dysmenorrhea. METHODS: Systematic searches were conducted in Scopus, Web of Science, PubMed, CINAHL, and MEDLINE. The articles must have been published in the last 10 years, had a sample exclusively of women with primary dysmenorrhea, had a randomized controlled trial design, and used interventions that included some form of manual therapy and/or electrotherapy techniques. Two reviewers independently screened articles for eligibility and extracted data. Difference in mean differences and their 95% CIs were calculated as the between-group difference in means divided by the pooled standard deviation. The I2 statistic was used to determine the degree of heterogeneity. RESULTS: Twelve selected studies evaluated interventions, with 5 evaluating electrotherapy techniques and 7 evaluating manual therapy techniques. All studies analyzed identified improvements in pain intensity and meta-analysis confirmed their strong effect. CONCLUSIONS: Manual therapy and electrotherapy are effective for the treatment of women with primary dysmenorrhea. Transcutaneous electrical nerve stimulation combined with thermotherapy and effleurage massage stands out for its effects on the intensity and duration of pain with the application of a few sessions and their long-term effects. IMPACT: Manual therapy techniques and electrotherapy methods reduce the pain intensity of women with primary dysmenorrhea. Quality of life and degree of anxiety improved significantly with manual therapy interventions. Transcutaneous electrical nerve stimulation combined with thermotherapy and effleurage massage are the interventions with which positive effects were achieved with fewer sessions.

Pain screening in youth with sickle cell disease: A quality improvement study.

BACKGROUND: Youth with sickle cell disease (SCD) face several challenges as they age, including increased pain frequency, duration, and interference. The purpose of this study was to (i) determine the feasibility of routine pain screening; (ii) identify and describe various clinical pain presentations; and (iii) understand preferences/resources related to engaging in integrative health and medicine (IHM) modalities within an outpatient pediatric SCD clinic. METHODS: During routine outpatient visits, patients aged 8-18 completed measures of pain frequency, duration, and chronic pain risk (Pediatric Pain Screening Tool [PPST]). Participants screening positive for (i) persistent or chronic pain or (ii) medium or high risk for persistent symptoms and disability on the PPST were asked to complete measures of pain interference, pain catastrophizing, and interest in/resources for engaging in IHM modalities. RESULTS: Between March 2022 and May 2023, 104/141 (73.8%) patients who attended at least one outpatient visit were screened. Of these 104 (mean age 12.46, 53.8% female, 63.5% HbSS), 34 (32.7%) reported persistent or chronic pain, and 48 (46.2%) reported medium or high risk for persistent symptoms and disability. Patients completing subsequent pain screening measures reported a mean pain interference T-score of 53.2 ± 8.8 and a mean pain catastrophizing total score of 24.3 ± 10.2. Patients expressed highest interest in music (55.6%) and art therapy (51.9%) and preferred in-person (81.5%) over virtual programming (22.2%). CONCLUSIONS: Comprehensive pain screening is feasible within pediatric SCD care. Classifying patients by PPST risk may provide a means of triaging patients to appropriate services to address pain-related psychosocial factors.

Is adding dry needling to a standard care protocol beneficial in patients with chronic neck pain? A randomized placebo-controlled trial.

PURPOSE: To evaluate the short-term effects of adding a dry needling therapy to a standard care protocol based on education, exercise and electrotherapy, compared to a sham procedure and to a standard care protocol in isolation in patients with chronic neck pain. MATERIAL AND METHODS: A randomized placebo-controlled trial was performed. The participants in the dry needling group received a standard care protocol based on patient education, therapeutic exercise and electrotherapy, as well as two sessions of dry needling in the upper trapezius, levator scapulae, and/or sternocleidomastoid muscles. The participants in the sham dry needling group received the same standard care protocol and two sessions of sham dry needling. The participants in the control group received the same standard care protocol. The outcomes measured were pain intensity, pressure pain threshold, neck disability, range of movement, activation of deep cervical flexor muscles, kinesiophobia, pain catastrophizing, anxiety, and depression. RESULTS: No significant group by time interactions were found for any of the outcome variables except for lower cervical spine range of movement (F = 3.79; p = 0.030). CONCLUSION: The addition of two sessions of dry needling in the superficial neck muscles to a standard protocol did not yield superior results compared to either the standard care alone or the standard care plus sham dry needling in patients with chronic neck pain in any outcome except for cervical range of movement.

Effectiveness of Bach Nien Kien Health Supplement in the Treatment of Patients With Symptomatic Knee Osteoarthritis.

BACKGROUND/AIM: Knee osteoarthritis (KOA) is the most common disease in adults. We conducted a clinical study to evaluate the efficacy and safety of Bach Nien Kien (BNK) in supportive therapy for patients with symptomatic KOA. PATIENTS AND METHODS: An open interventional study was performed on 60 patients aged 38 to 70 with the diagnosis of symptomatic KOA. The patients were assigned to a study group (SG) with 30 subjects and a control group (CG) with 30 subjects using a matching method. The patients in SG were treated with electroacupuncture, glucosamine supplement, and BNK, while the patients in CG received the same treatment without BNK. RESULTS: At the end of the 30-day treatment (d30), the SG had a reduction in VAS score compared to a pre-treatment level of 3.03±0.96 points, which was more than the CG of 2.5±0.90 points. The excellent result in the SG was 10%, and the CG had no excellent result. The good result in the SG was 56.7%, and the CG group was only 26.7%. The moderate and poor results in the CG were high, 63.3%, and 10%, respectively; in the SG, only 26.7% and 6.7%. The difference in overall treatment results between the SG and CG was statistically significant (p<0.05). During the 30-day treatment period in both groups, no patient reported any undesirable effects. CONCLUSION: Bach Nien Kien health supplement is effective and safe for controlling KOA symptoms and improving joint motion and quality of life for patients with symptomatic KOA.

The effect of physical interventions on pain control after orthodontic treatment: A systematic review and network meta-analysis.

OBJECTIVE: Pain is a frequent adverse reaction during orthodontic treatment, which can significantly reduce treatment compliance and compromise the expected treatment effect. Physical interventions have been used to alleviate pain after orthodontic treatment, but their effectiveness is controversial. This study used a network meta-analysis to assess the efficacy of various physical interventions typically used in managing pain after orthodontic treatment, with a view to provide evidence-based recommendations for representative interventions for orthodontic pain relief during peak pain intensity. METHODS: A systematic search of six electronic databases, from their respective inception dates, was conducted to identify relevant literature on the efficacy of various typical physical interventions for managing pain after orthodontic treatment. Literature screening was performed according to the Cochrane System Evaluator's Manual. Stata 16.0 was used to assess heterogeneity, inconsistency, publication bias, and sensitivity to generate an evidence network diagram and conduct a network meta-analysis. RESULTS: In total, 771 articles were reviewed to collect literature on interventions, including low-level laser therapy (LLLT), vibration, acupuncture, and chewing. Of these, 28 studies using a visual analog scale (VAS) as an outcome indicator were included. The results showed that LLLT, vibration, acupuncture, and chewing effectively relieved the pain symptoms in patients after orthodontic treatment. At 24 h post-treatment, LLLT (surface under the cumulative ranking curve [SUCRA] = 80.8) and vibration (SUCRA = 71.1) were the most effective interventions. After 48 h of treatment, acupuncture (SUCRA = 89.6) showed a definite advantage as the best intervention. CONCLUSION: LLLT, vibration, acupuncture, and chewing can alleviate pain associated with orthodontic treatment. Among these interventions, acupuncture was found to be the most effective at 48 h after orthodontic treatment. In addition, acupuncture demonstrated long-lasting and stable pain-relieving effects. However, further studies are needed to determine the most suitable equipment-specific parameters for acupuncture in relieving pain associated with orthodontic treatment.

A randomized controlled study on acupuncture for peri-operative pain after open radical prostatectomy.

OBJECTIVES: To evaluate the advantages of adding acupuncture to standard postoperative pain management for open radical prostatectomy (RP). MATERIALS AND METHODS: A randomized controlled trial (1:1:1) comparing routine postoperative analgesic care (control [CON]) vs the addition of press tack needle acupuncture (ACU) or press tack placebo acupressure (SHAM) for pain management after open RP was performed. A total of 126 patients were enrolled between February 2020 and April 2021. After open RP, the CON group received standard postoperative analgesia, the ACU group received long-term acupuncture with press tacks at specific points (P-6, Shenmen and SP-6) along with standard analgesia, and the SHAM group received placebo press tacks at the same acupuncture points alongside standard analgesia. The primary endpoint was postoperative pain measured on a numeric rating scale, the NRS-11, calculated as the area under the curve. The cumulative use of routine postoperative analgesics, time to first defaecation, and quality of life were analysed using the Kruskal-Wallis rank sum test, Fisher's exact test, and Pearson's chi-squared test. RESULTS: The ACU group reported significantly less postoperative pain compared to the SHAM (P = 0.007) and CON groups (P = 0.02). There were no significant difference in median (interquartile range) cumulative pain medication usage, time to first defaecation (CON: 37 [33, 44] h; SHAM: 37 [33, 42] h; ACU: 37 [33, 41] h; P > 0.9), or health status at discharge (EuroQol five-dimension, five-level general health assessment questionnaire: CON: 70 [65-83]; SHAM: 70 [60-80]; ACU: 70 [50-80]). CONCLUSION: Incorporating acupuncture into postoperative pain management can improve patient postoperative outcomes.

Ozone and Laser Effects on Dentin Hypersensitivity Treatment: A Randomized Clinical Study.

INTRODUCTION: The aim of this study was to evaluate and compare the clinical efficacy of diode laser and ozone gas in the treatment of dentin hypersensitivity (DHS). METHODS: One hundred thirty-two teeth from 44 patients with moderate DHS were randomized into 3 groups according to a split-mouth design. In the diode laser group, the operator irradiated the superficial dentin exposed with an 808-nm wavelength and incremental power from 0.2 to 0.6 W with a 20-second interval. In the ozone gas group, the operator applied a high dose of ozone (32 g/m3) for 30 seconds using a silicon cup. In the placebo group, no therapy was applied. The dentin sensitivity level was evaluated upon enrollment (T0), immediately after treatment (T1), 3 months post-treatment (T2), and 6 months post-treatment (T3) with a cold air blast challenge and tactile stimuli. The pain severity was quantified according to the visual analogue scale. The Wilcoxon signed rank test was used to scrutinize potential statistical disparities among the treatments. Statistical significance was predetermined at P < .05. RESULTS: A significant decrease of DHS was observed in the ozone gas group and the `diode laser group immediately after treatment and after 3 and 6 months of the therapy. After 6 months from the therapy, the sensitivity values in the teeth treated with ozone gas remained statistically lower than those treated with diode lasers (P < .05). CONCLUSIONS: A laser diode and ozone gas are both efficient as dentin sensitivity treatment. Ozone maintains an invariable effectiveness after 6 months.

Role of wet-cupping therapy in physiological and mental pains in patients with migraine: A quasi-clinical trial.

BACKGROUND: There is growing evidence of the potential benefits of wet-cupping therapy in reducing physiological pain severity in migraine; however, the role of this therapy on mental pain is unclear in this process. Therefore, this study aimed to examine the effectiveness of wet-cupping therapy on physiological and mental pains in patients with migraine. In this study, 72 migraine patients were treated with wet-cupping therapy and followed up after 1 month. METHODS: The severity of physiological and mental pain was measured before therapy, 10 minutes and 1 month following therapy. RESULTS: The study showed that patients in the wet-cupping therapy had a significantly lower mean value of physiological (0.42 vs 3.39; P < .001) and mental pain (1.60 vs 3.06; P < .001) compared to the patients in the control group, respectively. The mean value of the physiological was significantly decreased from 6.97 (baseline) to 0.73 (10 minutes) and 0.63 (1 month; P < .001) in the wet-cupping therapy patients, and the mean value of mental pain from 3.76 (baseline) to 0.71 (10 minutes) and 1.71 (1 month; P < .001). The mean values of physiological and mental pains were significantly reduced (from 7.80-3.39; P < .001) and (from 3.48-3.06; P = .0044), respectively. The level of physiological pain severity was significantly decreased with a decreasing level of mental pain severity at the posttest within the control (r = 0.5471; P = .0002) and the wet-cupping therapy (r = 0.3814; P .0412). CONCLUSION: This study showed that the physiological pain was controlled by the mental pain in the wet-cupping therapy.

The effectiveness of low-level laser therapy and low-intensity pulsed ultrasound in reducing pain induced by orthodontic separation: a randomized controlled trial.

BACKGROUND: The low-level laser therapy (LLLT) and low-intensity pulsed ultrasound (LIPUS) have been recently applied to control pain during orthodontic treatment. OBJECTIVE: To evaluate and compare the effectiveness of LLLT and LIPUS in reducing pain induced by orthodontic separation. STUDY DESIGN: A single-blinded randomized controlled trial. METHODS: One hundred and fifty patients were randomly assigned into three groups; LLLT group, LIPUS group, and control group. After 5 min from the separators' placement, the first dose of the laser or the ultrasound was applied, the second dose was applied after 24 h, and the third dose was applied after 48 h on both maxillary and mandibular first molars. The exposure of laser was for 20 s at each point (maxillary and mandibular first molars), with an 810-nm aluminum-gallium-arsenide (AlGaAs) diode laser on continuous mode. The output power set at 150 mW, the energy density of 4 J/cm2, and a laser spot diameter of 7 mm were applied. Whereas the frequency of ultrasonic toothbrush was 1.6 MHz; and average output intensity was 0.2 W/cm2. The application was for 20 min (5 min on each first molar). The control group received the separators without another intervention. A Visual Analog Scale (VAS 100 mm) was used to assess pain intensity at several time intervals during the first four days after the separators' placement. RESULTS: A total of 145 patients were assessed. There was a significant difference in pain perception among the three groups after 5 min (P = .002). The maximum pain level was reached after 24 h. However, the laser group and the ultrasound group showed a statistically significant decrease in pain scores compared to the control group at all the assessment time points (P < .001). Whereas there was no difference between the laser group and the ultrasound group in reducing the pain scores (P > .05). CONCLUSIONS: The LLLT and the LIPUS effectively reduce the separation pain when applied in multiple doses without differences between them. TRIAL REGISTRATION: This trial was registered with the German Clinical Trials Register (DRKS). ( https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID= DRKS00029991).

Effectiveness of myofascial release for adults with chronic neck pain: a meta-analysis.

BACKGROUND: Every second human will experience a phase of neck pain in their lifetime and a high rate of chronicity exists. Because of the complexity and multiple influencing factors, chronic pain conditions are associated with a long treatment and diagnostic process. This leads to a prolonged healing process and high costs. OBJECTIVE: To evaluate the effect of myofascial release on the variables of pain and range of motion in patients with chronic neck pain. METHOD: Selection criteria were set to create a search algorithm for a systematic search in the databases: PubMed, Google Scholar, EBM Reviews, Medline, CINAHL, PEDro, and Science Direct. The risk of bias and the methodological quality was analyzed with the PEDro scale. RESULT: Ten randomized controlled trials, with 549 participants met the eligibility criteria. The methodological quality was ranked from good to excellent. The myofascial release showed a significant difference in pain (p =  0.03), rotation to the right (p =  0.05), and lateral flexion to the right (p =  0.04), compared to other treatment methods. No significant effect was found for improvements in pressure pain threshold. CONCLUSION: Modest effects are observed in pain reduction, suggesting potential benefits of myofascial release in managing chronic neck pain. Further research with standardized protocols and direct comparisons to established therapies is crucial for a comprehensive understanding of myofascial release efficacy. CONTRIBUTION OF THE PAPER: What does the meta-analysis add to the current literature.

A randomized controlled trial investigating the impact of a single flash cupping session on patients with chronic lower back pain using multichannel surface electromyographic assessment.

BACKGROUND: Chronic lower back pain (CLBP) is one of the most common disorders worldwide. Flash cupping has the ability to relieve CLBP; nevertheless, its impact on CLBP and the likely mechanism of action have not been studied. OBJECTIVE: The goal of this study was to assess the impact of a single, brief cupping session on CLBP and low back muscle activity using multichannel surface electromyography (sEMG). METHODS: In this randomized controlled trial, 24 patients with CLBP were enrolled and randomly assigned to the control group (treated by acupuncture) and cupping group (treated by acupuncture and flash cupping). Acupuncture was applied on the shen shu (BL23), dachang shu (BL25), and wei zhong (BL40) acupoints in both the groups. A brief cupping treatment was applied to the shen shu (BL23), qihai shu (BL24), dachang shu (BL25), guanyuan shu (BL26), and xiaochang shu (BL27) acupoints on both sides of the lower back in the cupping group. The numeric rating scale (NRS) was used to assess therapy efficacy for lower back pain (LBP) before and after treatment. Surface EMG data collected during symmetrical trunk flexion-extension movements were utilized to measure lower back muscle activity and the effectiveness of LBP therapy. RESULTS: There was no statistically significant difference (P= 0.63) in pain intensity between the two groups before and after treatment. There was a statistically significant difference (P= 0.04) between the control group and the cupping group in the sEMG topographic map parameter CoGx-To-Midline. CONCLUSION: This study established a connection between the action mechanism of flash cupping and enhanced horizontal synchronization of lower back muscular activity.
