Abstract
BACKGROUND: The Lancet Series of Low Back Pain (LBP) highlighted the lack of LBP data from low- and middle-income countries (LMICs). The study aimed to describe (1) what LBP care is currently delivered in LMICs, and (2) how that care is delivered. METHODS: An online mixed-methods study. A Consortium for LBP in LMICs (n=65) was developed with an expert panel of leading LBP researchers (>2 publications on LBP) and multidisciplinary clinicians and patient partners with five years of clinical/lived LBP experience in LMICs. Quantitative data were analyzed using descriptive statistics. Two researchers independently analyzed qualitative data using deductive and inductive coding and developed a thematic framework. FINDINGS: Forty-seven (85%) of 55 invited panel members representing 32 LMICs completed the survey (38% women; 62% men). The panel included clinicians (34%), researchers (28%), educators (6%), and patient partners (4%). Pharmacotherapies and electrophysiological agents were the most used LBP treatments. The Thematic Framework comprised of eight themes: (1) Self-management is ubiquitous; (2) Medicines are the cornerstone; (3) Traditional therapies have a place; (4) Society plays an important role; (5) Imaging use is very common; (6) Reliance on passive approaches; (7) Social determinants influence LBP care pathway; and (8) Health systems are ill-prepared to address LBP burden. INTERPRETATION: LBP care in LMICs did not consistently align with the best available evidence. Findings will help research prioritization in LMICs and guide global LBP clinical guidelines. FUNDING: The lead author's Fellowship was supported by the International Association for the Study of Pain.

Abstract
BACKGROUND The burden of neurological conditions in north Africa and the Middle East is increasing. We aimed to assess the changes in the burden of neurological conditions in this super-region to aid with future decision making. METHODS In this analysis of the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 data, we examined temporal trends of disability-adjusted life-years (DALYs; deaths and disabilities combined), deaths, incident cases, and prevalent cases of 14 major neurological conditions and eight subtypes in 21 countries in the north Africa and the Middle East super-region. Additionally, we assessed neurological DALYs due to 22 potentially modifiable risk factors, within four levels of classification, during the period 1990-2019. We used a Bayesian modelling estimation approach, and generated 95% uncertainty intervals (UIs) for final estimates on the basis of the 2·5th and 97·5th percentiles of 1000 draws from the posterior distribution. FINDINGS In 2019, there were 441·1 thousand (95% UI 347·2-598·4) deaths and 17·6 million (12·5-24·7) neurological DALYs in north Africa and the Middle East. The leading causes of neurological DALYs were stroke, migraine, and Alzheimer's disease and other dementias (hereafter dementias). In north Africa and the Middle East in 2019, 85·8% (82·6-89·1) of stroke and 39·9% (26·4-54·7) of dementia age-standardised DALYs were attributable to modifiable risk factors. North Africa and the Middle East had the highest age-standardised DALY rates per 100 000 population due to dementia (387·0 [172·0-848·5]), Parkinson's disease (84·4 [74·7-103·2]), and migraine (601·4 [107·0-1371·8]) among the global super-regions. Between 1990 and 2019, there was a decrease in the age-standardised DALY rates related to meningitis (-75·8% [-81·1 to -69·5]), tetanus (-88·2% [-93·9 to -76·1]), stroke (-32·0% [-39·1 to -23·3]), intracerebral haemorrhage (-51·7% [-58·2 to -43·8]), idiopathic epilepsy (-26·2% [-43·6 to -1·1]), and subarachnoid haemorrhage (-62·8% [-71·6 to -41·0]), but for all other neurological conditions there was no change. During 1990-2019, the number of DALYs due to dementias, Parkinson's disease, multiple sclerosis, ischaemic stroke, and headache disorder (ie, migraine and tension-type headache) more than doubled in the super-region, and the burden of years lived with disability (YLDs), incidence, and prevalence of multiple sclerosis, motor neuron disease, Parkinson's disease, and ischaemic stroke increased both in age-standardised rate and count. During this period, the absolute burden of YLDs due to head and spinal injuries almost doubled. INTERPRETATION The increasing burden of neurological conditions in north Africa and the Middle East accompanies the increasing ageing population. Stroke and dementia are the primary causes of neurological disability and death, primarily attributable to common modifiable risk factors. Synergistic, systematic, lifetime, and multi-sectoral interventions aimed at preventing or mitigating the burden are needed. FUNDING Bill & Melinda Gates Foundation.

Abstract
BACKGROUND Neck pain is a highly prevalent condition that leads to considerable pain, disability, and economic cost. We present the most current estimates of neck pain prevalence and years lived with disability (YLDs) from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) by age, sex, and location, with forecasted prevalence to 2050. METHODS Systematic reviews identified population-representative surveys used to estimate the prevalence of and YLDs from neck pain in 204 countries and territories, spanning from 1990 to 2020, with additional data from opportunistic review. Medical claims data from Taiwan (province of China) were also included. Input data were pooled using DisMod-MR 2.1, a Bayesian meta-regression tool. Prevalence was forecast to 2050 using a mixed-effects model using Socio-demographic Index as a predictor and multiplying by projected population estimates. We present 95% UIs for every metric based on the 2·5th and 97·5th percentiles of 100 draws of the posterior distribution. FINDINGS Globally, in 2020, neck pain affected 203 million (95% uncertainty interval [UI] 163-253) people. The global age-standardised prevalence rate of neck pain was estimated to be 2450 (1960-3040) per 100 000 population and global age-standardised YLD rate was estimated to be 244 (165-346) per 100 000. The age-standardised prevalence rate remained stable between 1990 and 2020 (percentage change 0·2% [-1·3 to 1·7]). Globally, females had a higher age-standardised prevalence rate (2890 [2330-3620] per 100 000) than males (2000 [1600-2480] per 100 000), with the prevalence peaking between 45 years and 74 years in male and female sexes. By 2050, the estimated global number of neck pain cases is projected to be 269 million (219-322), with an increase of 32·5% (23·9-42·3) from 2020 to 2050. Decomposition analysis of the projections showed population growth was the primary contributing factor, followed by population ageing. INTERPRETATION Although age-standardised rates of neck pain have remained stable over the past three decades, by 2050 the projected case numbers are expected to rise. With the highest prevalence in older adults (higher in females than males), a larger effect expected in low-income and middle-income countries, and a rapidly ageing global population, neck pain continues to pose a challenge in terms of disability burden worldwide. For future planning, it is essential we improve our mechanistic understanding of the different causes and risk factors for neck pain and prioritise the consistent collection of global neck pain data and increase the number of countries with data on neck pain.

Abstract
To underscore the importance of evaluating the entrapment of the posterior femoral cutaneous nerve (PFCN) in patients exhibiting symptoms in the posterior thigh region. A 42-year-old male dentist, initially diagnosed with a semitendinosus muscle tear and persistent pain and tingling in the posterior thigh, sought treatment at our outpatient clinic. Despite unsuccessful physiotherapy, a comprehensive evaluation revealed an unusual entrapment of the PFCN between the sacrotuberous ligament and the semitendinosus muscle stump. The patient was subjected to a series of specialized therapeutic interventions, including soft tissue release, kinesiology taping, and lifestyle modifications. The patient's symptoms, including pain and tingling, were completely resolved, enabling him to sit on a stool for extended periods without discomfort. This case presentation emphasizes the need for physical therapists to consider the possibility of PFCN entrapment in patients experiencing pain and tingling in the posterior thigh. These symptoms can be easily mistaken for conditions such as sciatica or a hamstring muscle tear.

Abstract
Background Diabetic peripheral neuropathy (DPN) is one of the most common complications of diabetes mellitus (DM). DPN is the primary risk factor for diabetic foot ulcers that can cause amputation. Although several observational studies have investigated the morphological and biomechanical characteristics of peripheral nerves in DPN, interventional studies regarding the effectiveness of neurodynamic techniques (NDT) in DPN patients are confined to a handful. The effects of NDT on neuropathy severity, nerve conduction parameters, quality of life (QoL), and mechanosensitivity have not been explored yet in this population. Materials and Methods Forty type 2 DPN (T2DPN) patients, diagnosed based on an electrodiagnosis study, will be recruited into two groups. The experimental group will receive the tibial nerve's real proximal and distal slider techniques in addition to DPN standard treatment as a basic treatment, and the control group will receive the tibial nerve's sham proximal and distal slider techniques along with the basic treatment for eight sessions twice a week. Baseline and post-intervention assessments will be based on the Michigan diabetic neuropathy score (MDNS) (primary outcome), tibial nerve conduction parameters, neuropathy-specific quality of life (Neuro QoL) questionnaire, and straight leg raising range of motion (SLR ROM) (secondary outcomes). Results This study is expected to last approximately seven months, depending on recruitment. The results of the study will be published in a peer-reviewed journal. Conclusions The present study will evaluate the efficacy of NDT on the primary and secondary outcome measurements in DPN patients.

Abstract
BACKGROUND Dual-task conditions, which involve performing two tasks simultaneously, may exacerbate pain and further impair daily functioning in individuals with low back pain (LBP). Understanding the effects of dual-task conditions on postural control in patients with LBP is crucial for the development of effective rehabilitation programs. Our objective was to investigate the impact of dual-task conditions on postural control in individuals with LBP compared to those without LBP. METHODS We conducted a comprehensive search of Medline via PubMed, Scopus, the Cochrane Central Register of Controlled Trials, Web of Science, and EMBASE databases, with no language restrictions, from inception to January 1, 2023. The primary outcome measures of the study were velocity, area, amplitude, phase plane portrait, and path/sway length of the center of pressure (CoP). Standardized mean difference (SMD) effect sizes were calculated, and the quality of the studies was assessed using the Newcastle-Ottawa Scale (NOS). RESULTS From 196 studies, five involving 242 adults (≥ 18 years) met the inclusion criteria. Three studies were rated as high quality, while two were deemed moderate. In the included studies, 140 participants had non-specific LBP, while 102 participants did not report any symptoms, with mean ages of 36.68 (± 14.21) and 36.35 (± 15.39) years, respectively. Three studies had both genders, one exclusively included females, and one did not specify gender. Meta-analyses of primary outcomes revealed no significant differences in postural control between patients with LBP and pain-free controls during both easy and difficult postural tasks and cognitive load for velocity (easy: SMD - 0.09, 95% CI - 0.91 to 0.74; difficult: SMD 0.12, 95% CI - 0.67 to 0.91), area (easy: SMD 0.82, 95% CI - 2.99 to 4.62; difficult: SMD 0.14, 95% CI - 2.62 to 2.89), phase plane (easy: SMD - 0.59, 95% CI - 1.19 to 0.02; difficult: SMD - 0.18, 95% CI - 0.77 to 0.42), path/sway length (easy: SMD - 0.18, 95% CI - 0.77 to 0.42; difficult: SMD - 0.14, 95% CI - 0.84 to 0.55), and amplitude (easy: SMD 0.89, 95% CI - 1.62 to 3.39; difficult: SMD 1.31, 95% CI - 1.48 to 4.10). CONCLUSIONS The current evidence suggests that there are no significant differences in postural control parameters during dual-task conditions between individuals with non-specific LBP and pain-free subjects. However, due to the limited number of available studies, significant publication bias, and considerable statistical heterogeneity, definitive conclusions cannot be drawn. Therefore, further research comprising high-quality studies with larger sample sizes is necessary to obtain conclusive results. Trial registration PROSPERO CRD42022359263.

Abstract
BACKGROUND Rotator cuff tear (RCT) is one of the main causes of shoulder pain and dysfunction. Rotator cuff repair (RCR) is a common surgical procedure for the management of RCTs. Presence of myofascial trigger points (MTrP) as a result of surgical procedure can aggravate postoperative shoulder pain. The purpose of this protocol is to describe a randomized controlled trial design to evaluate the effect of implementing 4 sessions of myofascial trigger point dry needling (MTrP-DN) within a multimodal rehabilitation protocol following RCR surgery. METHODS Forty-six participants aged 40-75 will be recruited having postoperative shoulder pain after RCR and meeting the inclusion criteria. Participants will be randomly divided into 2 groups: One group will undergo MTrP-DN, manual therapy, exercise therapy and electrotherapy and the other will receive sham dry needling (S-DN), manual therapy, exercise therapy and electrotherapy. This protocol will cover 4 weeks of intervention. The primary outcome measure will be the Numeric Pain Rating Scale (NPRS) for pain. Secondary outcome measures will be Shoulder Pain and Disability Index (SPDI), range of motion (ROM), strength and adverse events. DISCUSSION This is the first study to investigate the use of 4 sessions of MTrP-DN in combination with a multimodal rehabilitation protocol for postoperative shoulder pain, restriction, weakness and dysfunction following RCR. The results of this study may help to determine the effect of MTrP-DN on various outcomes after RCR surgery. TRIAL REGISTRATION This trial was registered at the ( https://www.irct.ir ), (IRCT20211005052677N1) on 19/2/2022.

Abstract
BACKGROUND This study aimed to investigate the relationships of lumbar spine-hip discoordination during sit-to-stand (STD) and stand-to-sit (SIT) with pain and functional disability in chronic nonspecific low back pain (CNLBP) patients. METHODS A cross-sectional observational study was conducted in a biomechanics laboratory of the physical therapy department located at the School of Rehabilitation Sciences, Iran University of Medical Sciences (Tehran-Iran). A total of 16 CNLBP patients (men 9, female 7) aged 18-40 years (mean 31.48) were selected according to our eligibility criteria. Furthermore, ten reflective markers were placed on the spinous processes of T12 and S2, posterior and anterior superior iliac spines, greater trochanters, and lateral epicondyles. The patients were instructed to perform STD and SIT tasks at a preferred speed without using their hands. Relative phase angle was used as an indicator of coordination and was identified as the inverse tangent of angular displacement/angular velocity. Moreover, the relative phase angle between the lumbar spine and right and left hip joints was measured by subtracting the phase angle of the hip joint from the lumbar spine joint. The ratios of the total movements of the lumbar spine to the total movements of the right and left hip joints were also calculated in the sagittal plane. Finally, Pearson correlation coefficients (r) were utilized to assess the association between variables. RESULTS The results of this study indicated that kinematic parameters of the pain had statistically significant direct relationships with functional disability in CNLBP participants during STD and SIT with r values ranging from 0.57 (Pvalue = 0.021) to 0.85 (Pvalue<0.001) and 0.54 (Pvalue=0.053) to 0.82 (Pvalue<0.001), respectively. CONCLUSION Out of the results of this study, it could be stated that pain and functional disability play a major role in lumber spine-hip discoordination, and it altered the movement ratio in CNLBP patients during STD and SIT. In clinical practice, clinicians should improve lumber spine-hip discoordination in patients with CNLBP since there is a linear relationship between kinematic parameters of the pain and functional disability in patients with CNLBP.

Abstract
BACKGROUND Recurrent low back pain (RLBP) affects different structures in the lumbar spine. Exercise therapy is highly recommended as one of the first-line treatments. One crucial variable introduced to enhance RLBP is the external focus. The present study aimed to investigate the effects of external focus training on pain, the thickness of transverse abdominis (TrA), internal oblique (IO), external oblique (EO), and lumbar multifidus (LM) muscles, kinesiophobia, fear-avoidance beliefs, and disability of people with RLBP. METHODS This randomized-controlled trial consisted of 38 RLBP patients. Patients were randomly divided into two groups the treatment group (n=19) that received external focus training in addition to motor control training and the control group (n=19) that received motor control training alone. The primary outcome was pain intensity, and secondary outcomes were the thickness of TrA, IO, EO, LM muscles, kinesiophobia, fear-avoidance beliefs, and disability that were measured at the baseline and after 16 sessions of interventions. The interventions were performed three sessions weekly. RESULTS Reduction in pain intensity was more significant in the intervention group than in the control group (P<0.001, Cohen's d=-1.47). The thickness of TrA muscle in the contraction condition of the intervention group was significantly more on the left side (P<0.001, Cohen's d=1.05) than on the right side (P=0.03, Cohen's d=0.44). Other outcomes showed no significant differences. However, the Cohen's d effect size for the left IO (Cohen's d=0.57) and TKS (Cohen's d=-0.53) were moderate. CONCLUSION In RLBP patients, external focus and motor control training could effectively reduce the pain. Although this intervention could increase the thickness of the TrA muscle of RLBP, it has no significant effect on the thickness of IO, EO, and LM muscles. In addition, the obtained results indicated that this intervention has no significant effect on kinesiophobia, fear-avoidance beliefs, and disability..

Abstract
OBJECTIVE To evaluate the effectiveness of motor control training (MCT) compared with other physical therapist-led interventions, minimal/no intervention or surgery in patients with symptomatic lumbar disc herniation (LDH). DESIGN Systematic review and meta-analysis. DATA SOURCES Eight databases and the ClinicalTrials.gov were searched from inception to April 2021. ELIGIBILITY CRITERIA We included clinical trial studies with concurrent comparison groups which examined the effectiveness of MCT in patients with symptomatic LDH. Primary outcomes were pain intensity and functional status which were expressed as mean difference (MD) and standardised mean difference (SMD), respectively. RESULTS We screened 6695 articles, of which 16 clinical trials (861 participants) were eligible. Fourteen studies were judged to have high risk of bias and two studies had some risk of bias. In patients who did not undergo surgery, MCT resulted in clinically meaningful pain reduction compared with other physical therapist-led interventions (ie, transcutaneous electrical nerve stimulation (TENS)) at short-term (MD -28.85, -40.04 to -17.66, n=69, studies=2). However, the robustness of the finding was poor. For functional status, a large and statistically significant treatment effect was found in favour of MCT compared with traditional/classic general exercises at long-term (SMD -0.83 to -1.35 to -0.31, n=63, studies=1) and other physical therapist-led interventions (ie, TENS) at short-term (SMD -1.43 to -2.41 to -0.46, n=69, studies=2). No studies compared MCT with surgery. In patients who had undergone surgery, large SMDs were seen. In favour of MCT compared with traditional/classic general exercises (SMD -0.95 to -1.32 to -0.58, n=124, studies=3), other physical therapist-led interventions (ie, conventional treatments; SMD -2.30 to -2.96 to -1.64, n=60, studies=1), and minimal intervention (SMD -1.34 to -1.87 to -0.81, n=68, studies=2) for functional improvement at short-term. The overall certainty of evidence was very low to low. CONCLUSION At short-term, MCT improved pain and function compared with TENS in patients with symptomatic LDH who did not have surgery. MCT improved function compared with traditional/classic general exercises at long-term in patients who had undergone surgery. However, the results should be interpreted with caution because of the high risk of bias in the majority of studies. PROSPERO REGISTRATION NUMBER CRD42016038166.

Abstract
Objective Spinopelvic alignment is increasingly considered as an essential factor for maintaining an energy-efficient posture in individuals with normal or pathological status. Although several previous studies have shown that changes in the sagittal spinopelvic alignment may occur in patients undergoing total hip arthroplasty (THA), no review of this area has been completed so far. Thus, the objective of this scoping review was to summarize the evidence investigating changes in spinopelvic alignment and low back pain (LBP) following THA. Data sources We adhered to the established methodology for scoping reviews. Four electronic databases were systematically searched from inception-December 31, 2021. Study selection We selected prospective or retrospective observational or intervention studies that included patients with THA. Data extraction Data extraction and levels of evidence were independently performed using standardized checklists. Data synthesis A total of 45 papers were included in this scoping review, involving 5185 participants with THA. Pelvic tilt was the most common parameter measured in the eligible studies (n = 26). The results were not consistent across all studies; however, it was demonstrated that the distribution of pelvic tilt following THA had a range of 25° posterior to 20° anterior. Moreover, decreased sacral slope and lower pelvic incidence were associated with increased risk of dislocation in patients with THA. Lumbar spine scoliosis did not change significantly after THA in patients with bilateral hip osteoarthritis (5.50°(1.16°) vs. 3.73°(1.16°); P-value = 0.29). Finally, one study indicated that LBP improvement was not correlated with postoperative changes in spinopelvic alignment parameters. Several methodological issues were addressed in this study, including no sample size calculation and no type-I error adjustment for outcome multiplicity. Conclusions Changes in spinopelvic alignment may occur after THA and may improve with time. Patients with a THA dislocation usually show abnormal spinopelvic alignment compared to patients without a THA dislocation. LBP usually improves markedly over time following THA.

Abstract
OBJECTIVE To compare muscle strength and flexibility among a subgroup of women with extension-related chronic nonspecific low back pain (CNLBP) with healthy controls. METHODS In this case-control study, 32 subjects with and without extension-related CNLBP were tested (n = 16 in each group). Gluteal, abdominal, paravertebral, and hamstring strength, along with hip flexor flexibility and hamstring flexibility were compared between groups. Data were analyzed using the Mann-Whitney test (p < .007). RESULTS The CNLBP subgroup displayed significantly lower strength of all muscles analyzed (p < .007), with the exception of gluteus medius. The flexibility of the hip flexors and hamstrings were not significantly reduced among the women with CNLBP (p > .007). DISCUSSION The present study showed that alterations in muscle strength, but not flexibility, partly consistent with those previously hypothesized but not objectively reported, were present among a subgroup of women with extension-related CNLBP. These results may have implications for the selection of therapeutic exercises among this subgroup of people with CNLBP.

Abstract
Aim: To examine the reliability of rehabilitative ultrasound imaging performed to measure the thickness of the transverse abdominis, internal oblique, external oblique, and lumbar multifidus muscles in females with recurrent low back pain. Material and methods: A sample of 15 women was recruited. Two independent examiners recorded the thickness of their deep abdominal and spinal muscles by rehabilitative ultrasound imaging. Imaging scans of the transverse abdominis, internal oblique, and external oblique muscles were performed in the supine position and in the midaxillary line, between the lower edge of the ribcage and the iliac crest. Imaging of the lumbar multifidus was done in the prone position and at the level of the L5/S1 zygapophyseal joints. Imaging scans were performed bilaterally in rest and contraction, three times by the first examiner (at baseline, after two hours, and one week later) and once by the second examiner. Results: Good to excellent within-session intra-rater (ICC = 0.76, 0.97), good to excellent between-session intra-rater reliability (ICC = 0.73, 0.93), and good to excellent inter-rater reliability (ICC = 0.73, 0.98) were obtained. Conclusions: The results showed that rehabilitative ultrasound imaging can be used as an excellent reliable instrument by one or two examiners to measure the thickness of the transverse abdominis, internal oblique, external oblique and lumbar multifidus muscles in females with recurrent low back pain.

Abstract
OBJECTIVE Dry needling is a treatment technique used by clinicians to relieve symptoms in patients with tension-type headache (TTH), cervicogenic headache (CGH), or migraine. This systematic review's main objective was to assess the effectiveness of dry needling on headache pain intensity and related disability in patients with TTH, CGH, or migraine. METHODS Medline/PubMed, Scopus, Embase, PEDro, Web of Science, Ovid, Allied and Complementary Medicine Database/EBSCO, Cochrane Central Register of Controlled Clinical Trials, Google Scholar, and trial registries were searched until April 1, 2020, along with reference lists of eligible studies and related reviews. Randomized clinical trials or observational studies that compared the effectiveness of dry needling with any other interventions were eligible for inclusion. Three reviewers independently selected studies, extracted data, and assessed risk of bias. Random-effects meta-analyses were performed to produce pooled-effect estimates (Morris dppc2) and their respective CIs. RESULTS Of 2715 identified studies, 11 randomized clinical trials were eligible for qualitative synthesis and 9 for meta-analysis. Only 4 trials were of high quality. Very low-quality evidence suggested that dry needling is not statistically better than other interventions for improving headache pain intensity in the short term in patients with TTH (SMD -1.27, 95% CI = -3.56 to 1.03, n = 230), CGH (SMD -0.41, 95% CI = -4.69 to 3.87, n = 104), or mixed headache (TTH and migraine; SMD 0.03; 95% CI = -0.42 to 0.48, n = 90). Dry needling provided significantly greater improvement in related disability in the short term in patients with TTH (SMD -2.28, 95% CI = -2.66 to -1.91, n = 160) and CGH (SMD -0.72, 95% CI = -1.09 to -0.34, n = 144). The synthesis of results showed that dry needling could significantly improve headache frequency, health-related quality of life, trigger point tenderness, and cervical range of motion in TTH and CGH. CONCLUSIONS Dry needling produces similar effects to other interventions for short-term headache pain relief, whereas dry needling seems to be better than other therapies for improvement in related disability in the short term. IMPACT Although further high-methodological quality studies are warranted to provide a more robust conclusion, our systematic review suggested that for every 1 or 2 patients with TTH treated by dry needling, 1 patient will likely show decreased headache intensity (number needed to treat [NNT] = 2; large effect) and improved related disability (NNT = 1; very large effect). In CGH, for every 3 or 4 patients treated by dry needling, 1 patient will likely exhibit decreased headache intensity (NNT = 4; small effect) and improved related disability (NNT = 3; medium effect).

Abstract
BACKGROUND This systematic review aimed to investigate the effectiveness of proprioceptive neuromuscular facilitation (PNF) training on back pain intensity and functional disability in people with low back pain (LBP). METHODS Totally, five electronic databases, including PubMed/Medline (NLM), Scopus, Google Scholar, PEDro, and Cochrane Central Register of Controlled Clinical Trials were searched up to October 31, 2018. Clinical trials with a concurrent comparison group (s) that compared the effectiveness of PNF training with any other physical therapy intervention were selected. Publication language was restricted to English language articles. Methodologic quality was assessed using the PEDro scale. The measures of continuous variables were summarized as Hedges's g. RESULTS In total, 20 eligible trials were identified with 965 LBP patients. A large effect size (standardized mean difference [SMD]=-2.14, 95% confidence interval [CI]=3.23 to -1.05) and significant effect were observed favoring the use of PNF training to alleviate back pain intensity in patients with LBP. Moreover, large effect size and the significant result were also determined for the effect of PNF training on functional disability improvement (SMD=-2.68, 95% CI=-3.36 to -2.00) in population with LBP. A qualitative synthesis of results indicated that PNF training can significantly improve sagittal spine ROM. Statistical heterogeneity analysis showed that there was considerable statistical heterogeneity among the selected trials for the primary outcomes (I2 ≥ 86.6%). CONCLUSION There is a low quality of evidence and weak strength of recommendation that PNF training has positive effects on back pain and disability in LBP people. Further high-quality randomized clinical trials regarding long-term effects of PNF training versus validated control intervention in a clinical setting is recommendable.

Abstract
Background Headache is the most common neurological symptoms worldwide, as over 90% of people have noted at least one headache during their lifetime. Tension-type headaches, cervicogenic headaches, and migraines are common types of headache which can have a significant impact on social, physical, and occupational functioning. Therapeutic management of headaches mainly includes physical therapy and pharmacological interventions. Dry needling is a relatively new therapeutic approach that uses a thin filiform needle without injectate to penetrate the skin and stimulate underlying tissues for the management of neuromusculoskeletal pain and movement impairments. The main objective of this systematic review and meta-analysis is to evaluate the effectiveness of dry needling in comparison to other interventions on pain and disability in patients with tension-type headache, cervicogenic headache, and migraine. Methods/design We will focus on clinical trials with concurrent control group(s) and comparative observational studies assessing the effect of dry needling in patients with tension-type headache, cervicogenic headache, and migraine. Electronic databases from relevant fields of research (PubMed/ Medline, Scopus, Embase®, PEDro, Web of Science, Ovid, AMED, CENTRAL, and Google Scholar) will be searched from inception to June 2019 using defined search terms. No restrictions for language of publication or geographic location will be applied. Moreover, grey literature, citation tracking, and reference lists scanning of the selected studies will be searched manually. Primary outcomes of this study are pain intensity and disability, and secondary outcomes are cervical spine ROM, frequency of headaches, health-related quality of life, and TrPs tenderness. Studies will be selected by three independent reviewers based on prespecified eligibility criteria. Three reviewers will independently extract data in each eligible study using a pre-piloted Microsoft Excel data extraction form. The assessment of risk of bias will be implemented using the Cochrane Back and Neck Review Group 13-item criteria and NOS. Direct meta-analysis will be performed using a fixed or random effects model to estimate effect size such as standardized mean difference (Morris’s dppc) and 95% confidence intervals. Statistical heterogeneity will also be evaluated using the I2 statistic and the χ2 test. All meta-analyses will be performed using Stata V.11 and V.14 softwares. The overall quality of the evidence for the primary outcomes will be assessed using GRADE. Discussion All analyses in this study will be based on the previous published papers. Therefore, ethical approval and patient consent are not required. The findings of this study will provide important information on the value of dry needling for the management of tension-type headache, cervicogenic headache, and migraine. Trial registration PROSPERO registration number: CRD42019124125.

Abstract
Low back pain is a major health issue affecting the lumbopelvic muscles. Morphological changes in hip muscles, such as alterations in the muscle cross-sectional area and muscle volume, may occur in patients with low back pain. This systematic review was conducted to investigate whether patients with low back pain have macroscopic changes in their hip muscle morphology compared with asymptomatic, healthy individuals, based on current evidence. The electronic databases of PubMed/Medline, Ovid, Scopus, Embase® , and Google Scholar were searched from the inception to August 31, 2018. We only included full texts of original studies regarding macroscopic morphological alterations, including atrophy and fat infiltration, in hip muscles of patients with low back pain compared with asymptomatic controls. The quality of the included studies was determined using an assessment tool based on the Newcastle-Ottawa Scale. The scale was modified for the purposes of this study. Sixteen comparative observational studies were found eligible to be included in this review. Eleven were classified as high quality and four as moderate quality. The morphological changes in the psoas major, gluteus maximus, gluteus medius, gluteus minimus, and piriformis muscles were assessed in the primary studies. All selected studies were considered B level of evidence studies. The strength of conclusions for the psoas major, gluteal, and piriformis muscles was moderate. The results revealed that there is substantial controversy about the morphological changes in hip muscles in patients with low back pain; however, the majority of high-quality studies concluded that atrophy of hip muscles is evident in patients with low back pain. The psoas major muscle was the most commonly investigated hip muscle for morphological changes. Major methodological limitations of the included studies were identified and discussed. The present systematic review does not include a formal meta-analysis because of very significant differences in the primary studies in terms of study populations and methodologies. Finally, in clinical practice, it is recommended that physical therapists develop exercise programs to improve hip muscle function in patients with low back pain.

Abstract
OBJECTIVE This study aimed to evaluate the effect of high and low frequency of whole body vibration (WBV) on repositioning error in 3 different angles of lumbar flexion in patients with chronic low back pain. METHODS Twenty-four participants with chronic low back pain, aged between 20 and 35 years, were included in this randomized crossover trial study. Participants were randomly assigned into 2 groups as follows: (1) low frequency/high frequency, and (2) high frequency/low frequency. Participants received high-frequency (50 Hz) and low-frequency (30 Hz) WBV in a semi-squat position for 5 minutes in 2 sessions, with 2 weeks of rest. Before and after the WBV, lumbar repositioning error in 30% and 60% of lumbar full flexion and neutral position with eyes closed when standing was evaluated using an electrogoniometer. RESULTS The repositioning error was decreased in neutral, 30%, and 60% of lumbar flexion after the low-frequency and high-frequency WBV. Post hoc testing revealed that the effect of angle was not significant in repositioning error changes between high-frequency and low-frequency WBV (P > .05). However, the effect of low-frequency WBV on the repositioning error was significantly higher compared with high-frequency WBV (P < .05). CONCLUSION Low-frequency WBV might induce more improvement in the accuracy of lumbopelvic repositioning compared with high-frequency WBV with the method of WBV used in this study.

Abstract
Objective: To investigate the reliability and validity of an iPhone® application (iHandy® Level) for measuring active lumbar flexion-extension range of motion (ROM) in chronic nonspecific low back pain (CNLBP) patients. Methods: Fifteen CNLBP patients were recruited. The participants stood in a relaxed position and the T12-L1 and S1-S2 spinal levels were identified through palpation and were marked on the skin. Two blinded examiners used a gravity-based inclinometer and the application in order to measure ROM. The instruments were lined up appropriately and the participants were asked to perform maximum lumbar flexion following by maximum extension. First, each examiner placed the instruments over the T12-L1 level and then over the S1-S2 level during the movements. In order to calculate flexion-extension ROM, the measurement which was obtained from T12-L1 was subtracted from S1-S2. Intraclass correlation coefficient (ICC) models (3, k) and (2, k) were used in order to determine the intrarater and inter-rater reliability, respectively. The Spearman's correlation coefficients (rs ) and Bland-Altman plots were used in order to examine the validity. Results: Fair-to-excellent intrarater (ICC = 0.39-0.89) and moderate-to-good inter-rater reliability (ICC = 0.55-0.77) were observed using the inclinometer. Moreover, poor-to-good intrarater (ICC = 0.30-70) and inter-rater (ICC = 0.13-0.70) reliability were found with the application. The Spearman's correlation coefficients demonstrated low-to-moderate associations between the measures of the two instruments (rs ≥ 0.22). The Bland-Altman plots indicated that there was a significant difference between the instruments for measuring flexion ROM. The difference was not significant for measuring extension ROM. Conclusion: The iHandy® Level application does not have sufficient validity for measuring active lumbar flexion ROM in CNLBP patients.

Abstract
We study the role of partial autocorrelations in the reparameterization and parsimonious modeling of a covariance matrix. The work is motivated by and tries to mimic the phenomenal success of the partial autocorrelations function (PACF) in model formulation, removing the positive-definiteness constraint on the autocorrelation function of a stationary time series and in reparameterizing the stationarity-invertibility domain of ARMA models. It turns out that once an order is fixed among the variables of a general random vector, then the above properties continue to hold and follows from establishing a one-to-one correspondence between a correlation matrix and its associated matrix of partial autocorrelations. Connections between the latter and the parameters of the modified Cholesky decomposition of a covariance matrix are discussed. Graphical tools similar to partial correlograms for model formulation and various priors based on the partial autocorrelations are proposed. We develop frequentist/Bayesian procedures for modelling correlation matrices, illustrate them using a real dataset, and explore their properties via simulations.

Abstract
We develop a new class of models, dynamic conditionally linear mixed models, for longitudinal data by decomposing the within-subject covariance matrix using a special Cholesky decomposition. Here 'dynamic' means using past responses as covariates and 'conditional linearity' means that parameters entering the model linearly may be random, but nonlinear parameters are nonrandom. This setup offers several advantages and is surprisingly similar to models obtained from the first-order linearization method applied to nonlinear mixed models. First, it allows for flexible and computationally tractable models that include a wide array of covariance structures; these structures may depend on covariates and hence may differ across subjects. This class of models includes, e.g., all standard linear mixed models, antedependence models, and Vonesh-Carter models. Second, it guarantees the fitted marginal covariance matrix of the data is positive definite. We develop methods for Bayesian inference and motivate the usefulness of these models using a series of longitudinal depression studies for which the features of these new models are well suited.
