Rehabilitation of back pain in the pediatric population: a mixed studies systematic review.

BACKGROUND: A significant proportion of children and adolescents experience back pain. However, a comprehensive systematic review on the effectiveness of rehabilitation interventions is lacking. OBJECTIVES: To evaluate benefits and harms of rehabilitation interventions for non-specific low back pain (LBP) or thoracic spine pain in the pediatric population. METHODS: Seven bibliographic electronic databases were searched from inception to June 16, 2023. Moreover, reference lists of relevant studies and systematic reviews, three targeted websites, and the WHO International Clinical Trials Registry Platform were searched. Paired reviewers independently conducted screening, assessed risk of bias, and extracted data related to study characteristics, methodology, subjects, and results. Certainty of evidence was evaluated based on the GRADE approach. RESULTS: We screened 8461 citations and 307 full-text articles. Ten quantitative studies (i.e., 8 RCTs, 2 non-randomized clinical trials) and one qualitative study were included. With very low to moderate certainty evidence, in adolescents with LBP, spinal manipulation (1-2 sessions/week over 12 weeks, 1 RCT) plus exercise may be associated with a greater likelihood of experiencing clinically important pain reduction versus exercise alone; and group-based exercise over 8 weeks (2 RCTs and 1 non-randomized trial) may reduce pain intensity. The qualitative study found information provided via education/advice and compliance of treatment were related to effective treatment. No economic studies or studies examining thoracic spine pain were identified. CONCLUSIONS: Spinal manipulation and group-based exercise may be beneficial in reducing LBP intensity in adolescents. Education should be provided as part of a care program. The overall evidence is sparse. Methodologically rigorous studies are needed. TRIAL REGISTRATION: CRD42019135009 (PROSPERO).

Which patients with chronic low back pain respond favorably to multidisciplinary rehabilitation? A secondary analysis of a randomized controlled trial.

OBJECTIVES: The aim of this study was to identify prognostic variables at baseline associated with being responding favorably to multidisciplinary rehabilitation in patients with chronic low back pain (CLBP). METHODS: A responder analysis was conducted based on data from a randomized controlled trial with 26-week follow-up including 165 patients with CLBP treated at a Danish multidisciplinary rehabilitation center. Patients were dichotomized into responders and non-responders based on the outcome of a minimal clinically important difference of six points on the Oswestry Disability Index. The associations between prognostic variables and responders were analyzed using logistic regression. RESULTS: A total of 139 patients completed the study, of which 42% were classified as responders. Sex and employment status were statistically significant, with a decreased odds ratio (OR) of being a responder found for males compared to females (OR = 0.09, 95% CI = 0.02-0.48) and for being on temporary or permanent social benefits (OR = 0.28, 95% CI = 0.10-0.75) compared to being self-supporting or receiving retirement benefits. Statistically significant interaction (OR = 8.84, 95% CI = 1.11-70.12) was found between males and being on temporary or permanent social benefits. CONCLUSIONS: In patients with CLBP, female patients as well as patients who were self-supporting or receiving retirement benefits were significantly more likely than male patients or patients on temporary or permanent social benefits to be a responder to multidisciplinary rehabilitation.

Understanding social determinants of health and physical therapy outcomes in patients with low back pain: A scoping review.

BACKGROUND: Low back pain (LBP) is the number one cause of disability worldwide; however, it is not clear how social determinants of health (SDOH) impact care management and outcomes related to physical therapy (PT) services for patients with LBP. OBJECTIVE: The purposes of this scoping review are to examine and assimilate the literature on how SDOH and PT care relate to non-specific LBP outcomes and identify gaps in the literature to target for future research. METHODS: Data were extracted from eight electronic databases from January 2011 to February 2022. Reviewers independently screened all studies using the PRISMA extension for scoping review guidelines. Data related to study design, type of PT, type of non-specific LBP, patient demographics, PT intervention, SDOH, and PT outcomes were extracted from the articles. RESULTS: A total of 30,523 studies were screened, with 1961 articles undergoing full text review. Ultimately, 76 articles were identified for inclusion. Sex and age were the most frequent SDOH examined (88% and 78% respectively) followed by education level (18%). Approximately half of the studies that examined age, sex, and education level identified no effect on outcomes. The number of studies examining other factors was small and the types of outcomes evaluated were variable, which limited the ability to pool results. CONCLUSIONS: Sex and age were the most frequent SDOH examined followed by education level. Other factors were evaluated less frequently, making it difficult to draw conclusions. Study design and heterogeneity of determinants and outcomes were barriers to examining the potential impact on patients with LBP.

Disability reduction following a lumbar stabilization exercise program for low back pain: large vs. small improvement subgroup analyses of physical and psychological variables.

BACKGROUND: Little is known about why patients with low back pain (LBP) respond differently to treatment, and more specifically, to a lumbar stabilization exercise program. As a first step toward answering this question, the present study evaluates how subgroups of patients who demonstrate large and small clinical improvements differ in terms of physical and psychological changes during treatment. METHODS: Participants (n = 110) performed the exercise program (clinical sessions and home exercises) over eight weeks, with 100 retained at six-month follow-up. Physical measures (lumbar segmental instability, motor control impairments, range of motion, trunk muscle endurance and physical performance tests) were collected twice (baseline, end of treatment), while psychological measures (fear-avoidance beliefs, pain catastrophizing, psychological distress, illness perceptions, outcome expectations) were collected at four time points (baseline, mid-treatment, end of treatment, follow-up). The participants were divided into three subgroups (large, moderate and small clinical improvements) based on the change of perceived disability scores. ANOVA for repeated measure compared well-contrasted subgroups (large vs. small improvement) at different times to test for SUBGROUP × TIME interactions. RESULTS: Statistically significant interactions were observed for several physical and psychological measures. In all these interactions, the large- and small-improvement subgroups were equivalent at baseline, but the large-improvement subgroup showed more improvements over time compared to the small-improvement subgroup. For psychological measures only (fear-avoidance beliefs, pain catastrophizing, illness perceptions), between-group differences reached moderate to strong effect sizes, at the end of treatment and follow-up. CONCLUSIONS: The large-improvement subgroup showed more improvement than the small-improvement subgroup with regard to physical factors typically targeted by this specific exercise program as well as for psychological factors that are known to influence clinical outcomes.

[Research Progress in Data Acquisition and Intelligent Sensing Methods for Lumbar Electromyographic Signals].

Population aging trend is taking place in our country, and low back pain is a symptom of neuromuscular diseases of concern in the elderly. Accurately analyzing the disease of low back pain is important for both timely intervention and rehabilitation of patients. As a kind of bioelectrical signal, the acquisition and analysis of lumbar electromyography (EMG) signal is an important direction for the study of low back pain. The study reviews the acquisition of lumbar EMG by different types of sensors, introduces the signal characteristics of needle electrodes, surface electromyography electrodes and array electrodes, describes the use of signal algorithms, points out that wireless sensors and the use of deep learning algorithms are the direction of development, and puts forward prospects for its further development.

Introduction: Chronic low back pain is one of the main causes of incapacity for work in the world. It requires an interdisciplinary approach for the evolution of the patient. Until now, there is no consensus on the management of chronic low back pain, which generated the concern of this systematic review. Aim: To identify the effectiveness of physiotherapy protocols in the management of chronic low back pain. Methodology: A systematic search was carried out in the Pubmed, ScienceDirect, Scopus, Oxford, Wiley, Cochrane Library Plus, PEDro, Epistemonikos, Hinari and LILACS, Google Scholar, Teseo and PROSPERO databases, from the beginning of the databases until August, 2021. The selection criteria were defined according to the intervention and topic of the article. Results: Twenty-six studies were included in the qualitative synthesis, articles that did not meet the inclusion criteria were excluded. An effect was found in the control of pain and the reduction of disability and the main interventions are: muscular strengthening of the core and lower limbs, stretching of the lower limbs, lumbopelvic mobility and education or back school. The treatment frequency ranged from 2 to 3 times per week for 5 weeks. Conclusions: Greater effectiveness was found in pain control time and disability reduction, mainly related to core muscle strengthening and educational strategies.(AU)

Neuromuscular Control and Resistance Training for People With Chronic Low Back Pain: A Randomized Controlled Trial.

OBJECTIVE: To determine if adding lumbar neuromuscular control retraining exercises to a 12-week program of strengthening exercises had greater effect for improving disability than 12 weeks of strengthening exercises alone in people with chronic low back pain (LBP). DESIGN: Single-center, participant- and assessor-blinded, comparative effectiveness randomized controlled trial. METHODS: Sixty-nine participants (31 females; 29 males; mean age: 46.5 years) with nonspecific chronic LBP were recruited for a 12-week program involving lumbar extension neuromuscular retraining in addition to resistance exercises (intervention) or 12 weeks of resistance exercises alone (control). The primary outcome measure was the Oswestry Disability Index. Secondary outcome measures included the Numeric Rating Scale, Tampa Scale for Kinesiophobia, Pain Self-Efficacy Questionnaire, and the International Physical Activity Questionnaire. Outcomes were measured at baseline, 6 weeks, and 12 weeks. RESULTS: Forty-three participants (22 control, 21 intervention) completed all outcome measures at 6 and 12 weeks. Fourteen participants were lost to follow-up, and 12 participants discontinued due to COVID-19 restrictions. Both groups demonstrated clinically important changes in disability, pain intensity, and kinesiophobia. The difference between groups with respect to disability was imprecise and not clinically meaningful (mean difference, -4.4; 95% CI: -10.2, 1.4) at 12 weeks. Differences in secondary outcomes at 6 or 12 weeks were also small with wide confidence intervals. CONCLUSIONS: Adding lumbar neuromuscular control retraining to a series of resistance exercises offered no additional benefit over resistance exercises alone over a 12-week period.

Cognitive Functional Therapy compared with usual physiotherapy care in people with persistent low back pain: a mixed methods feasibility randomised controlled trial in the United Kingdom National Health Service.

OBJECTIVES: To determine the feasibility of completing a definitive randomised controlled trial (RCT), evaluating the clinical and cost-effectiveness of Cognitive Functional Therapy (CFT) in comparison to usual physiotherapy care (UPC), for people with persistent low back pain (LBP). DESIGN AND SETTING: A two-arm parallel feasibility RCT completed in a United Kingdom (UK) Secondary Care National Health Service (NHS) physiotherapy service. PARTICIPANTS: Sixty adult participants who reported LBP lasting for more than three months, that was not attributable to a serious (e.g. cancer) or specific (e.g. radiculopathy) underlying cause, were invited to participate. Participants were allocated at random to receive CFT or UPC. INTERVENTIONS: Cognitive Functional Therapy and Usual Physiotherapy Care for persistent LBP. MAIN OUTCOME MEASURES: The primary outcome was the feasibility of completing a definitive RCT, defined by recruitment of at least 5 participants per month, delivery of CFT per protocol and securing relevant and acceptable outcome measures. Data concerning study processes, resources, management and participant reported outcome measures were collected at baseline, 3, 6 and 12-month follow-up. RESULTS: Sixty participants (n = 30 CFT and n = 30 UPC) were recruited with 80% (n = 48), 72% (n = 43) and 53% (n = 32) retained at 3, 6 and 12-month follow-up respectively. NHS physiotherapists were trained to competence and delivered CFT with fidelity. CFT was tolerated by participants with no adverse events. Relevant and clinically important outcome data were collected at all time points (0.4%, 3%, 1% and 0.8% of data was missing from the returned outcome measure booklets at baseline and 3, 6 and 12-month follow-up respectively). The Roland-Morris disability questionnaire was considered the most suitable primary outcome measure with a proposed sample size of 540 participants for a definitive cluster RCT. CONCLUSION: It is feasible to conduct a randomised study of CFT in comparison to UPC for NHS patients. A future study should incorporate an internal pilot to address aspects of feasibility further, including participant retention strategies.

'Look up from the waiting list and see the bigger picture': a qualitative analysis of clinical specialist physiotherapist perspectives on low back pain care in Ireland.

INTRODUCTION: Healthcare systems are struggling to deliver high-quality low back pain (LBP) care. In 2012 specialist physiotherapist-led musculoskeletal (MSK) triage services were introduced in Irish hospitals to expedite patient care and alleviate pressure on elective orthopaedic/ rheumatology consultant clinics. Specialist physiotherapists have expertise to inform health service improvement and reform, but their perspectives of LBP healthcare delivery have received scant attention. OBJECTIVES: To explore specialist physiotherapists' perspectives on LBP care in Ireland, the barriers and facilitators to quality LBP care and the development of MSK interface services in primary care settings. DESIGN: Cross-sectional observational study using an anonymous electronic survey with thematic framework analysis of response data from open-ended questions. PARTICIPANTS: Thirty-four clinical specialist physiotherapists in Irish MSK triage services. RESULTS: Thematic analysis resulted in six overarching themes, grouped into two categories. One category pertained to LBP healthcare in Ireland with the following three themes: 1) Inadequate health services for patients with LBP; 2) Need for defined LBP clinical pathways; 3) Need for a multisectoral approach to spine health. Themes in the second category, pertaining to the development of community-based MSK interface services, were: 4) Concern regarding isolation from secondary care services; 5) Unrealistic expectations of MSK triage; 6) Improved communication and collaboration with primary care services. CONCLUSION: Specialist physiotherapists have concerns regarding LBP health services and persistence of a biomedical, secondary care-led approach. They advocate for investment in primary care multi-disciplinary teams, enhanced integration across primary and secondary care, development of a national clinical pathway and a multisectoral approach.

Eficacia del ejercicio de alta intensidad en personas con dolor lumbar crónico: una revisión sistemática / Efficacy of high-intensity exercise in people with chronic low back pain: A systematic review

El dolor lumbar crónico causa discapacidad e impacto socioeconómico. El ejercicio de alta intensidad muestra resultados positivos en otras enfermedades, pero no existe evidencia sobre esta patología. Se pretende determinar su eficacia en la calidad de vida relacionada con la salud, la discapacidad, la intensidad del dolor y la adherencia al tratamiento en personas con dolor lumbar crónico. Se realiza una revisión bibliográfica en Pubmed, PEDro y Scopus, incluyendo ensayos clínicos aleatorizados, guías de práctica clínica y revisiones sistemáticas en español, inglés o portugués (2012-2022). Además, se hace una búsqueda en bola de nieve. Se incorporan ocho ensayos clínicos aleatorizados (n=379). Se analizan diferentes modalidades de ejercicio de alta intensidad, que parecen mejorar la calidad de vida relacionada con la salud y reducir la discapacidad y la intensidad del dolor. Estos datos se deben tomar con cautela dada la poca cantidad de estudios y el riesgo de sesgo que presentan.(AU)

Chronic low back pain causes disability and socioeconomic impact. High-intensity exercise shows positive results in other diseases, but there is no evidence on this pathology. The aim is to determine its efficacy on health-related quality of life, disability, pain intensity and adherence to treatment in people with chronic low back pain. A literature review is conducted in Pubmed, PEDro and Scopus, including randomized clinical trials, clinical practice guidelines and systematic reviews in Spanish, English or Portuguese (2012-2022). In addition, a snowball search is performed. Eight randomized clinical trials (n=379) are incorporated. Different high-intensity exercise modalities are analyzed, which seem to improve health-related quality of life and reduce disability and pain intensity. These data should be taken with caution given the small number of studies and the risk of bias presented.(AU)

Rehabilitation of sick-listed LBP patients in occupational health with collaboration of the workplace.

The aim was to evaluate if rehabilitation procedures including occupational health (OH) and workplace participation increase return to work (RTW) rates among patients with subacute and chronic low back pain (LBP). A systematic review of randomized controlled trials was conducted using the PubMed and Cochrane databases. Main outcomes were RTW and days of sick leave. Interventions needed to be multidisciplinary including both OH and active workplace involvement in rehabilitation. Out of 1073 potentially eligible references, 8 met the inclusion criteria. Three studies had OH and 5 case managers involved in rehabilitation. Rehabilitation involving both OH and workplace improved RTW and decreased the number of sick leave days among LBP patients. Having case managers involved had no effect in RTW. In order to improve RTW, workplace visits and work ability meetings (WAMs) between OH and workplace are essential components in the rehabilitation process among patients with chronic LBP. Based on the study results, the authors suggest utilizing these co-operative interventions with workplaces in OH. High quality research investigating only the effect of WAMs in OH setting is needed in future. Int J Occup Med Environ Health. 2024;37(1):3-17.

Comparing physical therapy students' attitudes and beliefs regarding chronic low back pain and knee osteoarthritis: an international multi-institutional comparison between 2013 and 2020 academic years.

BACKGROUND: In 2013, physical therapy students demonstrated low guideline-adherent recommendations regarding chronic low back pain (CLBP) for spinal pathology, activity, and work. OBJECTIVES: To assess the differences in physical therapy students' attitudes, beliefs, and adherence to guideline recommendations regarding CLBP and knee osteoarthritis between 2013 and 2020. METHODS: In 2013 and 2020, second and fourth-year physical therapy students were recruited from 6 Belgian and 2 Dutch institutions. Attitudes and beliefs regarding CLBP and knee OA were evaluated using the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT), the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS), and a questionnaire regarding therapeutic exercise and knee osteoarthritis. A clinical vignette was used to measure guideline-adherent recommendations regarding spinal pathology, activity, and work. RESULTS: In 2013, 927 second-year and 695 fourth-year students; in 2020, 695 second-year and 489 fourth-year students; were recruited to participate in the study. Compared to 2013, students had less biomedical and stronger biopsychosocial attitudes and beliefs regarding CLBP, more guideline-adherent recommendations for activity, and more biopsychosocial beliefs regarding the benefits of exercise for patients with knee osteoarthritis in both the second and fourth year. Only fourth-year students in 2020 scored significantly better on HC-PAIRS and guideline-adherent recommendation relating to spinal pathology. No differences were found regarding work recommendations. CONCLUSIONS: Between 2013 and 2020, physical therapy students made a positive shift towards a more biopsychosocial approach to CLBP and knee osteoarthritis management. Guideline-adherent recommendations for CLBP concerning activity improved, however, concerning work and spinal pathology, it remained low.

Physical therapy for acute and sub-acute low back pain: A systematic review and expert consensus.

OBJECTIVE: To review the effectiveness of different physical therapies for acute and sub-acute low back pain supported by evidence, and create clinical recommendations and expert consensus for physiotherapists on clinical prescriptions. DATA SOURCES: A systematic search was conducted in PubMed and the Cochrane Library for studies published within the previous 15 years. REVIEW METHODS: Systematic review and meta-analysis, randomized controlled trials assessing patients with acute and sub-acute low back pain were included. Two reviewers independently screened relevant studies using the same inclusion criteria. The Physiotherapy Evidence Database and the Assessment of Multiple Systematic Reviews tool were used to grade the quality assessment of randomized controlled trials and systematic reviews, respectively. The final recommendation grades were based on the consensus discussion results of the Delphi of 22 international experts. RESULTS: Twenty-one systematic reviews and 21 randomized controlled trials were included. Spinal manipulative therapy and low-level laser therapy are recommended for acute low back pain. Core stability exercise/motor control, spinal manipulative therapy, and massage can be used to treat sub-acute low back pain. CONCLUSIONS: The consensus statements provided medical staff with appliable recommendations of physical therapy for acute and sub-acute low back pain. This consensus statement will require regular updates after 5-10 years.

A multicenter feasibility randomized controlled trial using a virtual reality application of pain neuroscience education for adults with chronic low back pain.

BACKGROUND: Chronic low back pain (CLBP) is a highly prevalent condition among adults and is correlated to high levels of pain, high disability, and lower quality of life. Pain neuroscience education (PNE) helps to explain the pain experience and can affect psychosocial factors, such as fear of movement, anxiety, socioeconomic status, work life satisfaction, etc. More recently, virtual reality (VR) programs have emerged allowing for immersive PNE experiences. OBJECTIVE: The purpose of this randomized clinical trial is to determine the feasibility of using a VR application for the delivery of immersive PNE (VR-PNE) and other activity training for patients with CLBP presenting to outpatient physical therapy (PT) clinics. METHODS: A two-arm, parallel group, randomized controlled feasibility trial of patients was conducted at 12 outpatient PT clinics from March 9, 2022, through September 9, 2022. The intervention group received PT as usual and VR-PNE while the control group received PT as usual. Between group feasibility, acceptability outcomes and other patient-reported outcomes were assessed at six weeks. RESULTS: A total of 595 individuals were evaluated for low back pain during the recruitment period. Seventy individuals were eligible and met definition for CLBP, 52 enrolled and 32 completed the trial. Participant adherence was 63.6% for VR-PNE and 63.2% for PT as usual. Participants found VR-PNE acceptable and reported satisfaction scores (0-100) of 87.37 ± 11.05 compared to 81.17 ± 23.72 in the PT as usual group. There were no significant differences between groups for the BBQ, BRS, FABQ-PA, FABQ-W, GROC, NPRS, NPQ, PCS, and PSEQ at 6 weeks. CONCLUSION: The results of the trial suggest that VR-PNE may be acceptable and feasible for patients with CLBP. Study procedures and PT delivery modifications should be considered for the next iteration of this study to improve follow-up assessment rates.

The effects of virtual reality training on postural sway and physical function performance on older women with chronic low back pain: A double-blind randomized clinical trial.

BACKGROUND: Chronic low back pain (CLBP) is known as an important debilitating health condition among older women. OBJECTIVE: This study aimed to evaluate the effects of eight-week virtual reality training (VRT) exercises on postural sway and physical function performance (PFP) among older women suffering from CLBP. METHODS: Twenty-seven older women presenting with CLBP were randomized into experimental and control groups. The experimental group was instructed to perform 30-minute VRT exercises three times a week for eight weeks. Plantar pressure variables [sway velocity (SV) and anterior-posterior (AP) and medial-lateral (ML) fluctuations of the center of pressure (CoP)], 30-second chair stand test (30CST), and timed up and go (TUG) test were recorded. RESULTS: The VRT group exhibited significant decreases in SV (p= 0.002), AP (p= 0.008), and ML (p= 0.02) fluctuations. Also, the performance of the VRT group in the 30CST and TUG tests significantly improved after the exercises (P< 0.001). CONCLUSION: According to the results, VRT and the program used in this study should be used to enhance balance and PFP in older women with CLBP who mostly prefer activities that are accessible and feasible in low-risk environments.

Comparison of trunk muscle activity during lumbar stabilization exercises on stable and unstable surfaces.

BACKGROUND: Lumbar stabilization exercises (LSE) provide dynamic trunk stability, promote muscle strength and endurance, and improve low back pain rehabilitation and performance. OBJECTIVE: To clarify the differences in trunk muscle activity during LSEs on stable and different unstable surfaces. METHODS: Fifteen healthy males performed three exercises (elbow-toe, hand-knee, and side bridge) on stable (floor) and unstable surfaces. Muscle activity of the bilateral rectus abdominis, internal oblique, external oblique, and erector spinae were recorded. Data were compared using the Friedman test. Pairwise comparisons were performed using Wilcoxon's signed rank test if significant differences were observed. RESULTS: In the elbow-toe exercise, muscle activity of the rectus abdominis and right internal oblique increased in the following order: floor, low-difficulty, and high-difficulty unstable surface. In the hand-knee exercise, muscle activity of the internal oblique on the lower-extremity elevated side, external oblique, and erector spinae on the upper-extremity elevated side were greater on unstable surface exercise performance. In the side bridge exercise, rectus abdominis muscle activity was highest on a high-difficulty unstable surface. CONCLUSION: Trunk muscle activity increased during exercise on unstable surfaces. Since the effects of unstable surfaces vary depending on muscle and exercise types, exercise difficulty and surface stability must be considered accordingly.

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.

Comparison of positional distraction with stabilisation exercises versus stabilisation exercises alone in the management of lumbar radiculopathy: A randomized controlled-trial.

OBJECTIVE: To compare the effects of positional distraction with stabilisation exercises versus stabilisation exercises alone in the management of lumbar radiculopathy. METHODS: The randomised controlled trial was conducted from July to December 2020 at the Institute of Physical Medicine and Rehabilitation, Dow University of Health Sciences, and the Neurosurgery ward of Civil Hospital, Karachi, and comprised individuals of either gender with lumbar radiculopathy pain who were randomised into positional distraction with stabilisation exercises group A and stabilisation exercise group B. The treatment duration was 3 sessions per week for 8 weeks. Intensity of pain and disability were assessed using the Visual Analogue Scale and the Roland Morris Disability Questionnaire, respectively. Data was analysed using SPSS 21. RESULTS: Of the 100 patients, 63(63%) were males and 37(37%) were females. Overall, 89(89%) were married. There were 50(50%) subjects in group A with mean age 39.42±6.36 years and 50(%) in group B with mean age 38.80±6.69 years. There was no significant difference in terms of age, gender and marital status between the groups (p>0.05). The study was completed by 96(96%) patients; 48(50%) in each of the 2 groups. Intragroup improvement post-intervention compared to baseline was significant (p<0.001) in both groups. Outcomes in group A were significantly better than in group B (p<0.05). CONCLUSIONS: Addition of positional distraction to stabilisation exercises was found to have superior effects compared to stabilisation exercise alone on pain and functional disability among patients with lumbar radiculopathy. Clinical Trial Number: NCT04427423 dated 27th April 2020.

The relationship between chronic diseases and the intensity and duration of low back pain.

BACKGROUND: Low back pain (LBP) is a worldwide problem that affects numerous people and limits their mobility. Several factors, including chronic diseases, increase the risk of developing LBP. To date, the information available about the relationship between chronic diseases and the intensity and duration of LBP is quite limited. AIM: The aim of the present study was to address the relationship between chronic diseases and both the intensity and duration of LBP. DESIGN: This is an observational cross-sectional study. SETTING: The study was conducted in the community of Saudi Arabia. POPULATION: 2181 adult participants (aged 18 years or more, mean age of 33 and standard deviation [SD] of ±11, 61% females) from Saudi Arabia with either recent or recurring LBP participated in the study. METHODS: The participants of this study were surveyed, and their demographic information was obtained. They were asked whether they had LBP during the past year, and if they had, they were asked about their LBP in terms of the pain intensity on a scale that runs from 0 to 10, where 0 indicates no pain and 10 indicates extreme pain. Further, the participants were asked how long their pain lasted (in days). They were also inquired whether they had any of the following chronic diseases: diabetes mellitus, high blood pressure, hypotension, arthritis, cardiopulmonary diseases, kidney diseases, and hypothyroidism. Logistic regression was used to analyze the relationships between both of LBP's intensity and duration, and the presence of chronic diseases, while adjusting for the potential effect of age and gender. RESULTS: A total of 2181 adults with either new onset of or recurrent LBP during the past 12 months participated in the present study. Of these, 356 (16%), who had LBP, suffered from one or more of the said chronic diseases. It was found that having one or more chronic diseases had statistically significant relationship with increased LBP's intensity (P=0.002), as well as prolonged duration (P=0.001). In particular, hypertension, arthritis, and hypothyroidism have statistically significant relationship with increased the intensity of the pain (P<0.05). Only, hypertension and arthritis have statistically significant relationship with increased the duration of pain (P≤0.001). CONCLUSIONS: The presence of chronic diseases was associated with a more intense and longer duration of LBP. CLINICAL REHABILITATION IMPACT: In view of the results of this study, we expect that those who have chronic diseases will have a longer duration of LBP and more intense pain.

The effectiveness of telerehabilitation-based exercise combined with pain neuroscience education for patients with facet joint arthrosis: A randomized controlled study.

OBJECTIVES: This study aimed to investigate the short-term effectiveness of exercise combined with PNE and exercise alone via telerehabilitation for patients with low back pain (LBP) caused by facet joint arthrosis (FJA). METHODS: This is a prospective, single-blind, randomized-controlled clinical trial. Forty-five patients with LBP caused by FJA were randomly allocated into three groups. The exercise (n = 15) and the exercise with PNE (n = 15) groups were provided interventions twice a week for six weeks via telerehabilitation. The control group (n = 15) was placed on the waiting list. The primary outcome measures were the numeric pain-rating scale (NPRS) at rest and with activity, The Oswestry disability index (ODI), the pain beliefs questionnaire (PBQ), and secondary outcome measures were short form-12v2 (SF-12v2) and the global rating of change score (GROC). RESULTS: The groups (52.00 ± 4.86, 46.7% female) were similar at baseline except for gender (p = 0.029). There was a significant group-by-time interaction for NPRS-rest (F = 4.276, p = 0.021), NPRS-activity (F = 12.327, p = 0.0001), the ODI (F = 23.122, p = 0.0001) and organic pain belief (F = 39.708, p = 0.0001). Further comparison with ANOVA showed that the exercise with PNE group showed better improvement in only organic pain belief (p = 0.0001). All groups reported improvements according to GROC, but it was higher in the intervention groups (p = 0.001). CONCLUSION: The patients who received exercise combined with PNE and exercise alone significantly improved pain intensity, disability and organic pain beliefs via telerehabilitation for patients with LBP caused by FJA compared to the control group. The PNE in addition to exercise may exhibit greater benefit in improving organic pain beliefs in short term. SIGNIFICANCE: This study highlights that combining exercise with PNE can lead to greater improvements compared to exercise alone or no intervention for FJA patients. The implementation of PNE in physiotherapy sessions has the potential to offer significant benefits. Furthermore, our results highlight the promising role of telerehabilitation as an effective method for delivering interventions to individuals with FJA.
