BACKGROUND: The World Health Organization states that low back pain is the leading cause for disability worldwide. Patients with chronic low back pain (CLBP) show important decreases in lumbar strength and can now be assessed by using the new isokinetic dynamometer BioniX Sim3 Pro which offers very detailed measurements. OBJECTIVE: To compare lumbar flexion and extension strength values, as well as extension-flexion ratio (EFR) based on isokinetic velocity and gender, for patients with CLBP on the BioniX Sim3 Pro. METHODS: A retrospective analysis was performed on data from 20 men and 22 women with CLBP. Maximum torque in flexion and extension was measured isometrically and isokinetically. Statistical analysis was performed on these parameters. RESULTS: EFR shows a downward trend with increasing speed of measurement (isometric to isokinetic 30∘/s and isokinetic 30∘/s to isokinetic 90∘/s, respectively): in men from 1.21 to 1.04 (p< 0.001) and from 1.04 to 0.93 (p= 0.207). In women, EFR decreased from 1.41 to 1.13 (p< 0.001) and from 1.13 to 1.00 (p= 0.144). CONCLUSIONS: Patients with CLBP have a decreased strength in lumbar extension and flexion compared to the age-corrected normal values of Bionix Sim3 Pro. With increasing speed of testing protocol, a decrease in EFR is observed in this population.

Abstract Background: MSK health is imperative for the active participation of an individual in society and MSK related disorders more direly affects a person's quality of life compared other non-communicable disease while it also negatively effects the health system and economy of a country. The current manuscript analyzed and describes the disease burden of MSK disorders in the EMRO region.Methods: This was a cross-sectional descriptive-analytical study conducted based on data published by the Global Burden of Disease Database for MSK disorders up to 2017. The study target comprised population from all countries of the EMRO region of World Health Organization. The present study considered, MSK disorders such as (rheumatoid arthritis), (osteoarthritis), (Low back pain), (neck pain), (gout) and (other Musculoskeletal disorders. The DALY index was used to measure total disease burden.Results: MSK disorders in the world and in the EMRO region was ranked 5th (4% of total disease burden) and 7th (5% of total disease burden) among all diseases in 2017, respectively. Women over 30 years of age in the EMRO region had the highest risk of MSK disorders compared to other regions and in addition, the DALY lost in EMRO region due to MSK disorders was higher in women of all age categories than men. According to the results of this study, Low back pain, Other musculoskeletal disorders and Neck pain had the highest prevalence and burden of disease in the EMRO region and the world. Bahrain, Iran, and Morocco had the highest incidence of MSK DALY score in the EMRO region, and Somalia, Djibouti, and Afghanistan had the lowest incidence of MSK disorders and DALY score, respectively.Conclusion: With the increase in geriatric population and obesity especially in developing countries, consequently, more people tend to suffer from MSK disorders and it is predicted that this spike will continue in the coming decades. Taking in to account the high prevalence and burden of MSK disorders, forces government and health-policy makers to focus more on preventive cares and rehabilitation.

Objective The purpose of the study was to examine the effectiveness of a novel supported dynamic lumbar extension with the abdominal drawing-in maneuver (ADIM) technique on stature change, deep abdominal muscle activity, trunk muscle fatigue, and pain intensity during prolonged sitting in chronic low back pain (CLBP) participants. Background Prolonged sitting can cause trunk muscle fatigue from continuous contraction of deep trunk muscles in seated postures. Deficiency of activity of deep muscles can reduce muscular support of the spine, causing stress on spinal structures, which could result in pain. Method Thirty participants with CLBP were randomly allocated: (a) control—sitting without exercise, and (b) intervention—supported dynamic lumbar extension with the ADIM technique. Results Compared to the intervention condition, the control condition demonstrated significantly greater deterioration in stature change, increased levels of deep trunk muscle fatigue, and an increase in pain during prolonged sitting. Conclusion The supported dynamic lumbar extension with the ADIM technique appears to provide a protective effect on detrimental stature change and deep trunk muscle fatigue. In addition, it prevented an increase in pain intensity during prolonged sitting in people with CLBP. Application Sedentary behavior harms health, particularly affecting the lower back. Clinicians can use the intervention to induce dynamic lumbar movement, and this exercise can maintain deep trunk muscle activity during prolonged sitting, thereby helping to prevent low back pain (LBP) problems.

Objective. Loss of disc height is commonly associated with chronic low back pain (CLBP). Isolated lumbar extension (ILEX) exercise for the lumbar extensors is recommended to treat CLBP and is suggested such exercise might promote disc healing and regeneration. This study examined a 12-week ILEX intervention on indirect determination of disc height and shrinkage through seated stadiometry, strength, pain, and disability. Design. A quasi-experimental wait-list controlled design was used. Nine participants underwent pretesting (T1), a 12-week control period, retesting (T2), a 12-week intervention period, and finally posttesting (T3). Seated stadiometry, ILEX strength, pain, and disability were measured at each time point. Results. No significant repeated-measures effects for any seated stadiometry variables occurred. Significant improvement across the intervention period (T2 to T3) was found for strength ( P <0.0001; effect size [ES] = 2.42). Change in pain was not significant for repeated effects ( P = 0.064); however, ES for the intervention period (T2 to T3) was moderate (ES = −0.77). Change in disability was significant between time point T1 and T3 ( P = 0.037) and ES for the intervention period (T2 to T3) was large (ES = −0.92). Pain and disability achieved minimal clinically important changes. Conclusions. This is apparently the first study to examine disc change in vivo after exercise in CLBP. Results of the present study, though supporting ILEX resistance training to improve strength, pain, and disability, did not find any effect on spinal height.

Icf Model

Background and PurposeThe World Health Organization's Classification of Functioning, Disability and Health (WHO-ICF) model was developed to describe, classify, and measure function in health care practice and research. Recently, this model has been promoted as a successor to the Nagi model by some authors in the physical therapy literature. However, conceptual work in demonstrating use of the WHO-ICF model in physical therapist management of individual patients remains sparse. The purpose of this case report series is to demonstrate the application of the WHO-ICF model in clinical reasoning and physical therapist management of acute and chronic low back pain.Case DescriptionTwo patients, 1 with acute low back pain and 1 with chronic low back pain, were treated pragmatically using the WHO-ICF model and other applicable models of clinical reasoning.InterventionManual therapy, exercise, and education interventions were directed toward relevant body structure and function impairments, activity limitations, and contextual factors based on their hypothesized contribution to functioning and disability.OutcomeBoth patients demonstrated clinically significant improvements in measures of pain, disability, and psychosocial factors after 3 weeks and 10 weeks of intervention, respectively.DiscussionThe WHO-ICF model appears to provide an effective framework for physical therapists to better understand each person's experience with his or her disablement and assists in prioritizing treatment selection. The explicit acknowledgment of personal and environmental factors aids in addressing potential barriers. The WHO-ICF model integrates well with other models of practice such as Sackett's principles of evidence-based practice, the rehabilitation cycle, and Edwards and colleagues’ clinical reasoning model. Future research should examine outcomes associated with the use of the WHO-ICF model using adequately designed clinical trials.

Aim: To determine the significant difference in lumbar multifidus activity within the patient with unilateral chronic low back pain and its association with lumbar range of motion. Study design: Analytical cross-sectional study Study setting and duration: Former institute of Dow University of Health Sciences, Karachi, Pakistan (Institute of Physical Medicine and Rehabilitation) which has become Sindh Institute of Physical Medicine and Rehabilitation and study duration was March 2020 to December 2020. Methodology: About 128 patients with unilateral chronic low back pain were assessed for the lumbar multifidus activity based on the percentage of maximum voluntary contraction through surface electromyography. Lumbar flexion and extension range of motion was measured through Modified-Modified Schober’s test. All the data were analyzed through the Statistical Package of Social Sciences 21. Nonparametric tests were employed. The level of significance was 0.05. Results: The lumbar multifidus activity was significantly increased (p<0.001) on the painful side than the non-painful side. However, there was a significant negative correlation (rh=- 0.551, -0.703; p<0.001) of only painful side lumbar multifidus activity with flexion and extension range of motion. Conclusion: Activity of painful side lumbar multifidus increases in unilateral chronic low back pain. Furthermore, it increases with a decrease in lumbar flexion and extension range of motion.
