Transcutaneous electrical nerve stimulation for the control of pain during rehabilitation after total knee arthroplasty: A randomized,blinded, placebo-controlled trial

This study evaluated the efficacy of transcutaneous electrical nerve stimulation (TENS) in reducing pain and hyperalgesia and increasing function after total knee arthroplasty (TKA). We hypothesized that participants using TENS during rehabilitation exercises would report significantly lower pain during range-of-motion (ROM) activity and fast walking but not at rest, would have less hyperalgesia, and would have better function than participants receiving placebo-TENS or standard care. We also hypothesized that change in ROM pain would differ based on psychological characteristics (trait anxiety, pain catastrophizing, and depression) and treatment group. This prospective, randomized study used intent-to-treat analyses in 317 participants after primary, unilateral TKA. Assessors, blinded to treatment allocation, measured pain, function (ROM and gait speed), and hyperalgesia (quantitative sensory tests) postoperatively and 6 weeks after surgery. Analgesic intake, anxiety, depression, and pain catastrophizing were also assessed. TENS participants used it 1 to 2 times per day at 42 mA (on average) and had less pain postoperatively during active knee extension (P = .019) and fast walking (P = .006) than standard care participants. TENS and placebo-TENS were not significantly different. TENS participants who scored low on anxiety and pain catastrophizing had a greater reduction in ROM pain at 6 weeks than those who scored high on these factors (P = .002 and P = .03). Both TENS and placebo-TENS participants had less postoperative mechanical hyperalgesia (P = .03–.01) than standard care participants. Supplementing pharmacologic analgesia with TENS during rehabilitation exercises reduces movement pain postoperatively, but a placebo influence exists and the effect is gone by 6 weeks. Patients with low anxiety and pain catastrophizing may benefit most from TENS.     

Clinical outcome of a headache-specific multidisciplinary treatment program and adherence to treatment recommendations in a tertiary headache center: an observational study

This study investigated the outcome of a 5-day headache-specific multidisciplinary treatment program (MTP) and the adherence to treatment recommendations in 295 prospectively recruited consecutive headache patients [210 migraine, 17 tension-type headache (TTH), 68 combination headache, including 56 medication-overuse headache (MOH)]. Headache frequency decreased from 13.4 (±8.8) to 8.8 (±8.0) days per month after 12–18 months. Forty-three percent of the participants fulfilled the primary outcome (reduction of headache frequency of ≥50%), which was less likely in patients with combination of migraine and TTH compared to migraine (OR = 3.136, p = 0.002) or TTH (OR = 1.029, n.s.). Increasing number of headache days per month (OR = 1.092, p ≤ 0.0001) and adherence to lifestyle modifications (OR = 1.269, p = 0.004) predicted primary outcome. 51 of 56 MOH patients were treated successfully. Thirty-five percent of the patients were adherent to pharmacological prophylaxis, 61% to relaxation therapy, and 72% to aerobic endurance sports. MTP is effective in headache treatment. Adherence to therapy was associated with better outcome.     

Effects of Reflexology and Progressive Muscle Relaxation on Pain,Fatigue, and Quality of Life during Chemotherapy in Gynecologic Cancer Patients

PurposeOur aim was to investigate the effect of reflexology and progressive muscle relaxation (PMR) exercises on pain, fatigue, and quality of life (QoL) of gynecologic cancer patients during chemotherapy.MethodsEighty participants were randomly assigned to one of four groups: reflexology, progressive muscle relaxation (PMR) exercises, both (reflexology + PMR), or a control group. Data were collected with a general data collection form, Brief Pain and Fatigue inventories, and Multidimensional Quality-of-Life Scale—Cancer.ResultsIn reflexology and reflexology + PMR groups, a significant decrease in pain severity and fatigue and an increase in QoL were found (p < .05). In the PMR alone group, pain severity and fatigue decreased significantly (p < .05), but there was no significant change identified in QOL (p > .05).ConclusionsReflexology and PMR exercises given to gynecologic cancer patients during chemotherapy were found to decrease pain and fatigue and increase QoL.     

A comparison of selected osteopathic treatment and relaxation for tension-type headaches

OBJECTIVE: The objective of this study was to compare the effects of osteopathic treatment and progressive muscular relaxation (PMR) exercises on patients with tension-type headache (TTH). BACKGROUND: Relaxation is generally accepted as a treatment for TTH. Osteopathy is considered by some practitioners to be useful for headache management but there is limited scientific evidence regarding the effectiveness. This study compares relaxation and relaxation plus selected osteopathic techniques in the treatment of people with TTH. DESIGN: This was a single-blind, randomized, clinical study using an experimental design. Twenty-nine patients with TTH according to the International Headache Classification Subcommittee, 2004, were recruited for this study and randomly placed in either a control or experimental group. Both groups practiced PMR exercises at home while the experimental group also received 3 osteopathic treatments. METHOD: All participants recorded headache frequency and intensity in a headache diary (HD) for 2 weeks pretreatment, and continued recording during the treatment period until reassessment for a total of 6 to 7 weeks. All tests of significance were set at P相似文献   

Clinical,psychological, and sensory characteristics associated with headache attributed to temporomandibular disorder in people with chronic myogenous temporomandibular disorder and primary headaches

BackgroundHeadache attributed to Temporomandibular Disorder (HATMD) is a secondary headache that may have features resulting in diagnostic overlap with primary headaches, namely, tension-type (TTH) or migraine. This cross-sectional study of people with both chronic myogenous TMD and primary headaches evaluated characteristics associated with HATMD.MethodsFrom a clinical trial of adults, baseline data were used from a subset with diagnoses of both TMD myalgia according to the Diagnostic Criteria for TMD (DC/TMD) and TTH or migraine according to the International Classification of Headache Disorders, 3rd edition. HATMD was classified based on the DC/TMD. Questionnaires and examinations evaluated 42 characteristics of facial pain, headache, general health, psychological distress, and experimental pain sensitivity. Univariate regression models quantified the associations of each characteristic with HATMD (present versus absent), headache type (TTH versus migraine), and their interaction in a factorial design. Multivariable lasso regression identified the most important predictors of HATMD.ResultsOf 185 participants, 114 (61.6%) had HATMD, while the numbers with TTH (n = 98, 53.0%) and migraine (n = 87, 47.0%) were similar. HATMD was more likely among migraineurs (61/87 = 70.1%) than participants with TTH (53/98 = 54.1%; odds ratio = 2.0; 95%CL = 1.1, 3.7). In univariate analyses, characteristics associated with HATMD included pain-free jaw opening and examination-evoked pain in masticatory muscles and temporomandibular joints (TMJ) as well as frequency and impact of headache, but not frequency or impact of facial pain. Lowered blood pressure but not psychological or sensory characteristics was associated with HATMD. Multiple characteristics of facial pain, headache, general health, and psychological distress differed between TTH or migraine groups. Few interactions were observed, demonstrating that most characteristics’ associations with HATMD were consistent in TTH and migraine groups. The lasso model identified headache frequency and examination-evoked muscle pain as the most important predictors of HATMD.ConclusionsHATMD is highly prevalent among patients with chronic myogenous TMD and headaches and often presents as migraine. In contrast to primary headaches, HATMD is associated with higher headache frequency and examination-evoked masticatory muscle pain, but with surprisingly few measures of facial pain, general health, and psychological distress. A better understanding of HATMD is necessary for developing targeted strategies for its management.Trial identification and registrationSOPPRANO; {"type":"clinical-trial","attrs":{"text":"NCT02437383","term_id":"NCT02437383"}}NCT02437383.

Transcutaneous Electrical Nerve Stimulation and Interferential Current Combined with Exercise for the Treatment of Knee Osteoarthritis: A Randomised Controlled Trial

Interferential current (IFC) and transcutaneous electrical nerve stimulation (TENS) are forms of electrical stimulation frequently used to treat knee osteoarthritis (OA). The relative effectiveness of these two modalities is currently unknown. The purpose of this study was to evaluate the effects of IFC and TENS, when used in conjunction with exercise, on pain and function in patients with knee OA. Forty-six subjects with radiographically confirmed OA were randomly assigned to one of three groups: TENS and standardised exercises, IFC and exercises or exercises alone. An electrical stimulator was used to apply IFC or TENS at 80 Hz for 20 minutes. All groups had a standardised exercise programme. Treatment was applied twice per week for 4 weeks. Outcomes included a 10-point pain rating scale for pain intensity and the Western Ontario and McMaster University Osteoarthritis Index (WOMAC). A two-way repeated measures ANOVA performed on the pain assessment score showed a statistically significant effect of time (p < 0.001), but not of experimental group (p = 0.813) or interaction (p = 0.067). A similar result was obtained for WOMAC score (p < 0.001, p = 0.241 and p = 0.130 for time, group and interaction effects, respectively). All treatment protocols led to significant improvements in pain and function over time. Neither IFC nor TENS displayed significant additional effects over exercise alone.     

Effects of Relaxation-Focused Nursing Program in Women with Ovarian Cancer: A Randomized Controlled Trial

BackgroundSurgical treatment is a major cause of hospitalization in ovarian cancer. In this process, physical problems, such as pain and changes in respiratory functions, and psychological problems, such as anxiety and stress, may develop.AimThis study aims to investigate the effects of the Relaxation-Focused Nursing Program on pain, anxiety, lung volume, level of knowledge, and nursing care satisfaction in ovarian cancer surgery.MethodA randomized controlled trial in which participants were randomly assigned to either the experimental (preoperative relaxation exercises and education; n = 24) or control (usual nursing care; n =22) groups. The intervention consisted of practicing four sessions of relaxation exercises and education in the hospital for two days before surgery. Data were collected using the Trait and State Anxiety Inventory, Surgical Information Form, and Perioperative Assessment Form. The results were analyzed using the Friedman and Wilcoxon tests.ResultsThe findings showed significant reductions in pain (p = .045) and anxiety scores (p < .001). The level of knowledge means scores were higher in the experimental group, but there was no significant difference between mean scores of spirometer volume and care satisfaction.ConclusionsThe program was more effective than usual nursing care in preoperative anxiety, pain, and level of knowledge. Although there was no difference between the care satisfaction scores of the patients, the reasons for care satisfaction were different in the program. Developing and implementing care that combines stress reduction interventions and preoperative education can improve the preoperative outcomes of patients.     

Effects of scapular stabilization and upper limb proprioception as an adjunct to cervical stabilization in chronic neck pain patients: A randomized controlled trial

BackgroundChronic neck pain is a prevalent health condition and a leading cause of disability worldwide. Prompt therapeutic measures are required to overcome this condition.ObjectivesTo evaluate the efficacy of incorporation of scapular stabilization and upper limb proprioceptive exercises to cervical stabilization exercises in patients with chronic neck pain (CNP).DesignA single-blinded randomized controlled design.MethodsA sample of convenience was deployed to recruit twenty-eight patients having CNP (18–45 years) and was randomized into two groups: group A (cervical stabilization exercises group) and group B (scapular stabilization and upper limb proprioceptive exercises group + cervical stabilization exercises). Pain intensity, disability, sleep quality, quality of life, scapular muscles strength and proprioception were assessed at 4 weeks follow up to determine the efficacy of the intervention.ResultsA mixed model ANOVA was used. A statistically significant (p < 0.05) group by time interaction for pain intensity (p = 0.000), scapular muscles strength of all muscles (p = 0.000) was observed. Significant group interaction for absolute error (p = 0.00), for pain (p = 0.001), disability (p = 0.04) and scapular muscle's strength (p = 0.000) was also demonstrated.ConclusionThe results indicated that scapular stabilization and upper limb proprioceptive exercises when combined with cervical stabilization exercises are more beneficial in alleviating pain and disability and improving scapular muscle strength and proprioception in patients with CNP.     

Comparison of two different techniques of electrotherapy on myofascial pain

This study was designed to compare the effects of Transcutaneus Electrical Nerve Stimulation (TENS) and Electrical Muscle Stimulation (EMS) on myofascial trigger point (MTrP) of the upper trapezius muscle. A total of 40 patients were randomly divided into three groups. All patients had active MTrP in one side of the upper trapezius muscles. Group I was treated with TENS and trapezius-stretching exercises; Group II was treated with EMS and trapezius-stretching exercises and Group III, the control group, had only trapezius-stretching exercises. Subjective pain intensity with VAS, range of motion (ROM), and pain threshold (PT) were assessed before, immediately after two week treatment and 3 months after treatment. Group I had a statistically significant reduction in VAS (P<0.01), increase in PT and ROM (p<0.05) at end of the treatment when compared with the control group. Only VAS was significantly improved (p<0.05) in the Group II patients. At the end of the third month, both groups showed highly significant improvement (p<0.01) in VAS and PT (but not ROM). There was no statistical difference in none of parameters between EMS and TENS groups in any time (p>0.05). In conclusion, TENS seem to be more effective immediately after treatment but in long term evaluation there is no significant superiority of two electrotherapy techniques on each other.     

Headache-related work disability in young men

Based on the knowledge that migraine and tension-type headache (TTH) are associated with reduced effectiveness at work and impairment of function in social roles, we studied the different influences that these primary headaches have on work in a specialized and homogeneous population. We studied 140 consecutive male patients, aged 18–35 years, attending an outpatient headache clinic at the Neurology Department of an Army General Hospital. Using International Headache Society (IHS) criteria, 60 patients were diagnosed with migraine and 80 patients with TTH. The impact of headache on work during the preceding 2 months was assessed using a selfadministered questionnaire, based on MIDAS. Two parameters of work disability were derived: the lost work days (LWD) and the days with reduced effectiveness while being at work (REWD). Of 142 LWD due to headaches, 95 (66.9%) were attributable to migraine and 47 (33.1%) to TTH (plt;0.001). Of 490 REWD, 120 (24.4%) were reported by migraineurs and 370 (75.5%) by TTH patients (p<0.001). The number of LWD in migraine was significantly higher (p<0.001) than in TTH group; the number of REWD in TTH group was significantly higher (p<0.001) than in migraine group. Pain intensity was the main factor contributing to disability at work in migraine group (plt;0.001), in contrast with TTH group in which there was no statistical difference (p>0.05) between pain intensity and duration of pain. Patients with migraine were much more likely to report actual lost workdays because of headache whereas TTH was responsible for the largest proportion of decreased work effectiveness. Assessing headache severity with an objective method (i.e. questionnaire) may improve headache care and lead to proper treatment decisions. Special attention must be given to particular populations.

Transverse oscillatory pressure in management of cervical radiculopathy: A randomised controlled study

BackgroundCervical radiculopathy is an important subgroup of neck disorders causing severe pain and disability.ObjectivesThe study assessed the effect of transverse oscillatory pressure (TOP) on pain intensity and functional disability of patients with cervical radiculopathy.MethodsTwenty-six individuals with unilateral radiating neck pain were randomly allocated into Group A (8 males and 5 females) and Group B (6 males and 7 females). Participants in the two groups received kneading massage, cryotherapy, and active isometric exercises to the posterior paraspinal muscles, trapezuis, and sternomastoid muscles. TOP was administered to Group A, whereas Group B served as control. Treatment was applied three times per week for 4 weeks, making 12 treatment sessions for each participant. Visual analogue scale and Neck Disability Index were used to assess pain intensity and neck disability, respectively, at baseline, 2 weeks, and 4 weeks. Data were analysed using repeated-measures analysis of variance.ResultsThere was a significant improvement in pain intensity and neck functional disability of patients between baseline, 2^nd week, and 4^th week of treatment sessions in Groups A and B (p < 0.05). There was a significant reduction in pain intensity in Group A (f = 7.08, p < 0.05) at the 2^nd week and 4^th week compared with Group B.ConclusionIt can be concluded that TOP reduces pain faster in patients with cervical radiculopathy.     

Comparing Diazepam Plus Fentanyl With Midazolam Plus Fentanyl in the Moderate Procedural Sedation of Anterior Shoulder Dislocations: A Randomized Clinical Trial

BackgroundThe reduction of shoulder dislocation requires adequate procedural sedation and analgesia. The mixture of midazolam and fentanyl is reported in the literature, but long-acting benzodiazepines in conjunction with fentanyl are lacking.Study ObjectiveOur aim was to compar e IV diazepam with IV midazolam in moderate procedural sedation (based on the classification of the American Society of Anesthesiologists) for the reduction of shoulder dislocation.MethodsThis was a randomized controlled clinical trial conducted from April 2019 to December 2019 in the emergency department of a university-affiliated hospital in Tehran, Iran. Participants were adult patients (aged 18–65 years) with anterior shoulder dislocation. Group A (n = 42) received diazepam 0.1 mg/kg plus fentanyl 1 μg/kg IV and group B received midazolam 0.1 mg/kg plus fentanyl 1 μg g/kg IV. Main outcomes measured were onset of muscle relaxation, time taken to reduction, total procedure time, number of the reduction attempts, patient recovery time, the occurrence of the adverse effects, amount of the pain reported by the patients using visual analog scale, and patients and physicians overall satisfaction with the procedure using a Likert scale question.ResultsEighty-one patients were included. The mean ± standard deviation time of the onset of the muscle relaxation and time taken to reduction was shorter in the diazepam plus fentanyl group (p = 0.016 and p = 0.001, respectively). Adverse effects and pain relief were not statistically different between the two groups. Patient recovery time and total procedure time was shorter in the midazolam plus fentanyl group (p = 0.008 and p = 0.02, respectively). The overall satisfaction of patients and physicians was higher in the diazepam plus fentanyl group.ConclusionsAs compared with midazolam plus fentanyl, diazepam plus fentanyl was superior in terms of the onset of the muscle relaxation, patient and physician satisfaction, and time taken to reduction.     

Randomised trial of IV metoclopramide vs IV ketorolac in treatment of acute primary headaches

IntroductionHeadache is one of the most common neurological conditions among emergency department visits (ED), although the best therapy has not been identified yet. Therefore, in the current study, we aimed to compare the pain-relieving effect of metoclopramide and ketorolac in acute primary headaches patients.MethodsThis double-blind, randomised clinical trial was conducted at Golestan Hospital, Ahvaz, Iran. This research involved all adult patients with acute primary (migraine or tension-type) headaches presented to the ED. Pain intensity was assessed with 0 to 10 verbal Numeric Rating Scales (NRS). The subjects were randomised into 10 mg intravenous (IV) metoclopramide or 30 mg IV ketorolac groups. Pain score and drug adverse reactions were compared between the two groups at baseline, 15, 30, and 60 min after baseline.Results108 patients completed this trial and were equally divided into two groups (mean age of 34 ± 8.54 years; 57.4% female). Before treatment, the mean pain score was 6.9 and 6.8 in metoclopramide and ketorolac groups, respectively (p > 0.05). Metoclopramide failed to provide more improvement in pain score at 30 min (p = 0.55) and 60 min (p = 0.15) from baseline. There were no serious adverse events in this study. Only five patients required rescue medication which four of them were in ketorolac group.ConclusionWe were unable to reject the null hypothesis that there would be no difference in pain outcomes between metoclopramide and ketorolac.     

Effect of conscious abdominal contraction on the activation of periscapular muscles in individuals with subacromial pain syndrome

BackgroundSynergism between shoulder and trunk muscles seems to be effective to increase periscapular muscle activation in asymptomatic subjects. The influence of conscious contraction of the abdominal muscles has not yet been studied in non-athlete subjects with pain. The study aimed to investigate the effect of the instruction for conscious activation of the abdominal muscles on the activity of the scapulothoracic muscles during shoulder exercises in subjects with subacromial pain syndrome.MethodThirty subjects with unilateral pain (mean age 52 ± 11 years) participated in this study. Three isometric and five dynamic exercises for the scapulothoracic muscles were assessed. The group without instruction just repeated the exercises, while the instruction group was evaluated before and after conscious abdominal training. The linear mixed model analysis was used to compare the muscle activation between groups.FindingsDifferences between groups after the conscious abdominal contraction for activation of middle and lower trapezius on the symptomatic side in the “Full can”(p = 0.03; effect size:0.92 middle trapezius); (p = 0.02; effect size:0.96 lower trapezius) and “Knee Push” (p = 0.01; effect size:0.75 lower trapezius). For asymptomatic side, the exercises “External Rotation Kneeling” (p = 0.04; effect size: 0.81 lower trapezius); (p = 0.00; effect size: 2.09 serratus anterior), “Knee Push” (p = 0.04; effect size:1.24 serratus anterior) and “Wall Slide” (p = 0.01; effect size: 1.03 serratus anterior).InterpretationConscious contraction of the abdominal muscle immediately alter the activation of the serratus anterior muscle during closed kinetic chain exercises on the asymptomatic side and increased activation of trapezius on the symptomatic side during shoulder open kinetic chain exercise.     

The Effect of Progressive Relaxation Exercise on Physiological Parameters,Pain and Anxiety Levels of Patients Undergoing Colorectal Cancer Surgery: A Randomized Controlled Study

PurposeThis study aimed to determine the effect of progressive relaxation exercises on physiological parameters, pain, anxiety, and serum cortisol levels in patients undergoing colorectal cancer surgery.DesignThis study is a randomized controlled study and has been registered at the Clinical Trial Registry Center (ID: NCT04731428).MethodsThe study was conducted on 63 patients (experimental group = 31, control group = 32), who were scheduled for elective laparoscopic-colorectal surgery in the general surgery clinic of a university hospital in Istanbul between March 2018 and May 2019 and met the inclusion criteria. The patients in the experimental group were given progressive relaxation exercises for 15 minutes preoperatively and on postoperative days 1, 2, and 3 after breathing exercise training. The routine treatments and care process of the patients in the control group were maintained. The preoperative and postoperative pain and anxiety levels of both groups were evaluated. Blood pressure, heart rate and respiratory rate, oxygen saturation, and serum cortisol levels were measured at certain time intervals before and after the relaxation exercise.FindingsThe patients in the experimental group had lower postoperative pain and anxiety levels and a lower rate of using opioid analgesic on postoperative day 0 compared to the control group. Progressive relaxation exercise had no statistically significant effect on serum cortisol or physiological parameters (P > .05).ConclusionsProgressive relaxation exercise did not affect cortisol levels and vital signs but decreased pain and anxiety, and relatively increased tissue oxygenation, appearing an effective, safe, and practicable nursing intervention.     

Classification and clinical features of headache patients: an outpatient clinic study from China

This study aimed to analyze and classify the clinical features of headache in neurological outpatients. A cross-sectional study was conducted consecutively from March to May 2010 for headache among general neurological outpatients attending the First Affiliated Hospital of Chongqing Medical University. Personal interviews were carried out and a questionnaire was used to collect medical records. Diagnosis of headache was according to the International classification of headache disorders, 2nd edition (ICHD-II). Headache patients accounted for 19.5% of the general neurology clinic outpatients. A total of 843 (50.1%) patients were defined as having primary headache, 454 (27%) secondary headache, and 386 (23%) headache not otherwise specified (headache NOS). For primary headache, 401 (23.8%) had migraine, 399 (23.7%) tension-type headache (TTH), 8 (0.5%) cluster headache and 35 (2.1%) other headache types. Overall, migraine patients suffered (1) more severe headache intensity, (2) longer than 6 years of headache history and (3) more common analgesic medications use than TTH ones (p < 0.001).TTH patients had more frequent episodes of headaches than migraine patients, and typically headache frequency exceeded 15 days/month (p < 0.001); 22.8% of primary headache patients were defined as chronic daily headache. Almost 20% of outpatient visits to the general neurology department were of headache patients, predominantly primary headache of migraine and TTH. In outpatient headaches, more attention should be given to headache intensity and duration of headache history for migraine patients, while more attention to headache frequency should be given for the TTH ones.     

Music Listening as a Postanesthesia Care Unit (PACU) Nursing Intervention for Laparoscopic Radical Prostatectomy Patients: A Randomized Comparative Clinical Trial

PurposeRandomized comparative mixed method approach with qualitative inquiry study's aim sought to determine if there was a difference in pre/post-intervention State-Trait Anxiety Inventory (STAI) scores and postanesthesia pain scores between two music listening groups of laparoscopic radical prostatectomy patients.DesignProspective randomized comparative mixed method approach with a qualitative inquiry.MethodsSample size of 77 male participants assigned by a table of random numbers to Spotify patient-preferred music selection Group I (n = 37) or minimalist hypnotic music with guided relaxation breathing (MHMGRB) instructional narrative Group II (n = 40). Outcome measures used patients’ STAI questionnaire and reported PACU admission and discharge pain scores.ResultsBoth Groups I and II had reduced pain scores at discharge as compared to admission; both groups had a significant reduction (P = .046 Group I, and Group II (P = .002), but changes for comparative groups (I and II) were not significant between the two groups (P = .53).ConclusionsStudy revealed that both patient-preferred selected music and MHMGRB can meaningfully reduce patients’ anxiety and PACU pain scores.     

Effects of Different Therapeutic Exercise Modalities on Migraine or Tension-Type Headache: A Systematic Review and Meta-Analysis with a Replicability Analysis

The primary aim of this study was to review the effect of exercise in comparison with a non-active treatment on pain intensity, frequency of headache episodes, headache duration, quality of life, medication use, and psychological symptoms, in patients with migraine or tension-type headache (TTH). A systematic search was conducted in various electronic databases to identify all relevant studies: Medline (PubMed), PEDro, EBSCO and Google Scholar. Clinical trials assessing the effects of exercise interventions in patients with primary headaches were selected. Methodological quality was evaluated using the Cochrane Risk of Bias Tool and PEDro scale and qualitative analysis was based on classifying the results into levels of evidence according to the GRADE. 19 studies (2776 participants; 85% female) were included. The meta-analysis showed statistically significant differences in pain intensity for aerobic training in patients with migraine (SMD = -0.65; 95% CI = -1.07 to -0.22, very low certainty evidence) and for strength training in patients with TTH (SMD = -0.84; 95% CI = -1.68 to- -0.01, very low certainty evidence). Statistically significant differences were also found in the medication use (SMD = -0.51; 95% CI = -0.85 to -0.17, low certainty evidence). Low transparency, replicability and high risk of bias were found. Aerobic training has a small to moderate clinical effect on pain intensity and medication use on migraine patients, with very low to low certainty of evidence. Strength training showed a moderate clinical effect with very low quality of evidence in patients with TTH. Exercise could be considered as clinically relevant for the management of patients with primary headaches, but the presence of low certainty of evidence and low transparency and replicability limited its clinical application.PerspectiveThis article presents current evidence about exercise interventions in patients with primary headaches, including migraine and tension-type headache. Existing findings are reviewed, and relevant data are provided on the effectiveness of each exercise modality, as well as its certainty of evidence and clinical applicability.     

Effect of Benson and progressive muscle relaxation techniques on sleep quality after coronary artery bypass graft: A randomized controlled trial

ObjectiveThis study aimed to investigate the effect of Benson relaxation (BR) and progressive muscle relaxation (PMR) techniques on the sleep quality of patients undergoing coronary artery bypass graft (CABG) surgery.MethodThis study was a three-arm, parallel, randomized controlled trial. 120 patients who underwent CABG surgery at two academic hospitals in an urban area of Iran were randomly allocated into three groups (40 per group): the BR, PMR, and control groups. Patients in the BR and the PMR groups performed relevant exercises twice a day for four weeks. Sleep quality was measured before and immediately after the intervention using Pittsburgh Sleep Quality Index.ResultsWithin-group comparison in the BR (t = 3.51, p = 0.001) and the PMR (t = 4.58, p < 0.001) group showed that the overall sleep quality showed a significant improvement after the intervention when compared to baseline. The between-group comparison showed that both the BR and PMR groups showed significant improvements in subjective sleep quality (F = 3.75, p = 0.02), habitual sleep efficiency (F = 4.81, p = 0.01), and overall sleep quality (F = 5.53, p = 005) when compared to the control group after the intervention. However, no statistically significant differences were identified among the three study groups in terms of sleep latency, sleep duration, sleep disturbances, sleeping medication, and daytime dysfunction after the intervention (p > 0.05).ConclusionThe study showed that a four-week program of both PMR and BR can be effective in the overall improvement of sleep quality in patients following CABG. Further research is required to replicate the findings of the present study.
