 Concerning the effectiveness of training on people with chronic low back pain, the present study aimed to evaluate the effect of postural restoration institute (PRI) training on lower limb kinematics during walking in middle-aged subjects with discogenic low back pain.

 In this prospective observational quasi-experimental study, 42 people participated in three groups: people without low back pain (healthy group, n=14) and people with low back pain in two groups (intervention group, n=14; and control group, n=14). Kinematic data were recorded by 7 Qualisys cameras with a frequency of 100 Hz in the pretest and post-test. Analysis of variance with repeated measures was used in SPSS software version 23 at a significance level 0.05.

 The results showed that people with low back pain in the intervention and control groups walk with a slower velocity, lower cadence, and shorter step length than healthy individuals for both right and left limbs. However, after the PRI training, the intervention group showed a significant increase in those three variables. Furthermore, there were significant differences between the healthy group and the two groups of intervention and control in the range of motion (ROM) for the pelvis in the sagittal and frontal planes, the right hip joint in the horizontal plane, the right ankle in the frontal plane, the left hip joint in the sagittal and horizontal planes as well as the left ankle in the sagittal plane. After applying PRI, the differences between the healthy and the intervention groups regarding the pelvis ROM on the sagittal plane, the right ankle ROM on the sagittal plane, the left hip joint ROM on the frontal plane, and the left knee ROM on the sagittal plane were minimized and became insignificant.

 The present study’s findings confirmed the effectiveness of using PRI training in improving biomechanical indicators, such as the range of joint movements and increasing the velocity and step length of walking, to treat and manage the performance of people with discogenic chronic low back pain.

Chronic low back pain is one of the most common debilitating occupational diseases. It seems that the frequency of this type of back pain is increasing, especially among young military staff. The aim of this study was to evaluate the causes of chronic low back pain according to interpretation of MRI reports in military personnel of army land forces of the Islamic Republic of Iran.

In this descriptive cross-sectional study, the data of military personnel with chronic low back pain, referring to the Neurosurgery Council of Khanevadeh Hospital, Tehran in 2016 were extracted. The information included demographic and occupational characteristics of the patients, clinical findings, and MRI reports. We used chi-square and Fischer exact tests for data analysis at the significance level of 95%.

326 male military personnel with chronic low back pain were evaluated. The mean age of the subjects was 37.3 ± 0.6 years. The most common MRI finding was disc herniation which was detected in 174 cases (53.3%). low back pain was most frequent in the combat branch, which included 114 cases (34.9%). There was no statistically significant correlation between MRI findings and types of military branches (P=0.071). The highest frequency of disc herniation belonged to the patients between 20 and 29 years of age (p=0.002) and the highest frequency of degenerative changes was seen in the patients over 50 years of age (p=0.005).

The most important finding of this study was the low mean age of the patients with chronic low back pain who were in their active working years. We suggest revision of the trend of periodic examinations of military personnel, ergonomics of the work environment and military training.

Chronic back pain is one of the most common chronic pains which various methods have been proposed to manage and reduce pain, including participating in sports rehabilitation programs. Therefore, the aim of the present study was to investigate the effectiveness of specialized yoga exercises on pain, functional capacity and range of motion of women with non-specific chronic back pain.

The statistical sample was 50 women suffering from non-specific chronic low back pain in Amol city, who were selected by available sampling method and randomly assigned to two experimental groups (25 people) and control group (25 people). The tools used in this research were McGill Pain Questionnaire, 6-minute fast walking functional test and waist flexion range measurement by Kinovea software before and 48 hours after the last session of yoga exercises. The experimental group performed specialized yoga exercises for 24 sessions of 60 minutes. The research design was a pre-test-post-test with a control group, and univariate covariance analysis (ANCOA) was used to analyze the data.

The obtained results showed that this yoga training program can reduce the pain of women with chronic low back pain (p≤ 0.05) and improve functional capacity (p ≤ 0.001) and increase the range of motion of the back (p ≤ 0.001).

Due to the simultaneous use of mental and strengthening exercises, specialized yoga exercises can improve psychological factors such as fear of movement, fear of pain, and subsequently improve the range of motion of the back and improve the functional capacity of patients.

Chronic low back pain is one of the most common and costly musculoskeletaldisorders in societies and is an important clinical and socio-economic epidemic, mostly in industry andnon-industry. The aim of this study was to a systematic review of the effectiveness of exercise protocolson lumbar proprioception in patients with chronic nonspecific low back pain.

From internal and external search engines, including Scopus, Semantic Scholar,Google Scholar, Pubmed, ISC, SID, Magiran, Irandoc, and Doaj with time limit 2010 to 2021 and the keywordsexercises, proprioception, non-specific, and chronic low back pain, the present study was doneusing PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes).

Results :

Nine articles were selected based on inclusion criteria. These studies mainly focused on systematicreview effectiveness of exercise protocols on sensation and low back pain in people with non-specificchronic low back pain.

According to the research reviewed in the present study, it seems that exercise rehabilitationprotocols activate, strengthen, maintain, and increase the central region of the body, especially deepmuscles, particularly the multifidus and transverse abdomen, by retraining the pelvic lumbar region. Thediaphragm and diagonal of the abdomen and pelvic floor, which play a role in the important segmentalstability of the lumbar spine, improve the sense of depth and pain in patients with chronic nonspecificlow back pain.

Chronic Low back pain (LBP) is one of the top 10 diseases that account for the most years of life with disability worldwide.

The research method was a semi-experimental pre-test-post-test type with a control group and a 45-day follow-up period. The statistical population of this research included all women with chronic Low back pain who referred to the hospital and specialized pain clinics in Isfahan city in the summer quarter of 1401. In this research, 30 patients suffering from chronic back pain were selected by available sampling method and randomly assigned to experimental and control groups (15 patients in each group). The experimental group received 8 sessions of 90 minutes during two months of treatment based on emotional efficiency, but the control group did not receive any intervention. The questionnaires used in this research included pain anxiety, pain acceptance. The experimental group received mindfulness-based stress reduction therapy during 8 90-minute group sessions, but no intervention was performed on the control group. The data was analyzed through SPSS-23 software and with the analysis of variance test with repeated measures.

Treatment based on emotional efficiency had a significant effect in reducing pain anxiety symptoms and improving pain acceptance in the post-examination and follow-up stages.

Treatment based on emotional efficiency is suggested as an effective treatment in health centers to improve pain acceptance and reduce pain anxiety in women with chronic low  back pain.

Studies have shown that carrying and holding objects requires the coordination of lower limb and trunk muscles, and is considered as a risk factor in causing low back pain. The aim of this study was to evaluate the level of activity of selected trunk and thigh muscles in forward and backward bending with different loads in people with and without chronic low back pain (CLBP).

In a semi experimental study, 31 subjects in two groups, 15 people with CLBP and 16 healthy people participated voluntarily. Subjects performed forward and backward bending in 4 positions without applying external load with 2, 5, and 10% of body mass during 6 seconds (2 seconds standing, 2 seconds bending forward and 2 seconds back). The electrical activity of eight muscles was recorded using an EMG device.

The results showed that the external load significantly affects the level of muscle activity. Also, there was a significant difference between the two groups as level of activity was higher in CLBP group. Also, the amount of load had a significant effect on the level of activity of different muscles in the groups, as the effect of 5% body mass load on the level of activity of rectus abdominis, internal oblique and multifidus was higher in CLBP group. Also, the effect of a load of 10% body mass on the level of activity of external oblique, thoracic erector spinae, lumbar erector spinae, and biceps femoris were higher in CLBP group. In addition, the effect of a load of 10% body mass on the level of activity of the gluteus maximus was higher in the healthy group.

In order to prevent muscle fatigue and ultimately to prevent the development or spread of pain, it is recommended to strengthen the muscles that had the highest level of activity when the external load increased.

According to evidence, sports activities and vitamin D, in addition to their role in developing physical health, have a considerable impact on cognitive, behavioral and mood disorders. In the present study, the effectiveness of core stabilization exercises and vitamin D consumption on quality of life (QL) and mental health (MH) of women with chronic low back pain was investigated.

This clinical trial study was performed on women with chronic low back pain. First, 48 patients were selected by available sampling method, then randomly divided into 4 groups: control, exercise, vitamin D and combined (exercise+vitamin D). Core stabilization exercises were performed by training and combined groups for 8 weeks, and vitamin D and combined groups took vitamin D (50,000 IU) weekly. SF-36 QL and general health (GHQ) questionnaires were used to collect data. Data analysis was performed using paired t-test and  one-way analysis of variance at a significance level of P< 0.05.

Vitamin D levels were lower than normal in all subjects. The QL and MH of women with low back pain improved after exercise, vitamin D intake, and combined intervention. The combined intervention was associated with a greater increase in QL compared to the other two therapeutic interventions and the development of MH compared to vitamin D intake.

It seems that therapies using core stabilization exercises, vitamin D intake or combination intervention can help people with low back pain and low levels of vitamin D in improving QL and MH.

Background & Aim:

Low back pain refers to a pain felt in the lumbar and sacrum regions of the spine. The aim of this study was to investigate the effect of movement pattern exercises on plantar pressure variables in people with chronic low back pain during walking.

Materials & Methods:

The present study was a quasi-experimental study with a pre-test and post-test design along with a control group. The study subjects, who were selected from the clients of the health and wellness center of Mohaghegh Ardabili University, Ardabil, Iran, were randomly divided into 10 people with chronic back pain (experimental group) and 10 people with back pain (control group). The subjects of the experimental group performed movement pattern exercises for 6 weeks, but the control group did not perform any exercises during this period of 6 weeks. Plantar pressure values were recorded during pre-test and post-test by foot scan device (sampling rate: 300 Hz). Two-way analysis of variance was used for statistical analysis of data. All analysis was done at significant level of 0.05 with SPSS 22 software.

Results showed that the peak of the vertical component at the heel contact (p = 0.009) and the vertical loading rate (p = 0.013) in the experimental group during post-test was lower compared to the pre-test. Pairwise comparison showed that the peak force in the second metatarsal bone in the experimental group was lower in the post-test compared to the pre-test (p=0.018).

Objective (s):

 Chronic low back pain is one of the most common chronic diseases that influence people's health and quality of life. The first line of non-medical management of chronic low back pain is psychological interventions. The current scoping review aimed to determine psychological interventions usually are used to treat chronic low back pain.

This scoping review examined studies published in English language with related keywords including ‘chronic low back pain’, ‘cognitive behavior therapy’, ‘behavioural/behavioral therapy’, ‘mindfulness’, ‘mediation’, ‘stress reduction’, ‘biofeedback’, ‘pain education’, ‘counselling’ and ‘acceptance and commitment therapy’ in PubMed. The data were extracted and tabulated to summarize evidence. In addition, information on instruments used to measure pain were addressed.

In all 156 papers was retrieved. Of these, 21 papers fulfilled the inclusion criteria. 19 articles out of 21 articles had a control group. The findings of the study showed that cognitive behavioral therapy, behavioral therapy, mindfulness and biofeedback were used more than other types of interventions. The results of cognitive behavioral therapy, behavioral therapy and mindfulness interventions confirmed their effectiveness, but using biofeedback intervention did not show certain result in the treatment of chronic back pain. The Numerical Rating Scale (NRS) was the most widely used instrument for pain assessment.

The findings showed that psychological interventions were effective in the treatment of chronic low back pain (especially back pain with psychosomatic causes). In cases where chronic low back pain has a specific cause, psychological intervention alone is not effective and should be used in combination with clinical interventions or other non-medical interventions such as rehabilitation.

Musculoskeletal discomforts are one of the most common occupational diseases of nurses. In this regard, the present study aims to investigate the effectiveness of acceptance and commitment therapy on anxiety sensitivity and alexithymia in nurses with chronic low back pain.

This was a semi-experimental study with pretest-posttest and a control group. The statistical population included nurses suffering from chronic low back pain in Tehran in 2019. The sample included 30 nurses with low back pain selected using available sampling method. They were randomly assigned into case and control groups. Data collection tools included anxiety sensitivity and alexithymia questionnaires. Accordingly, the experimental group received eight 90-minute sessions of therapy based on acceptance and commitment, but the control group did not receive any intervention.

The results of the present study indicated that treatment based on acceptance and commitment in nurses with chronic low back pain significantly reduced anxiety sensitivity (physical, cognitive and social) and alexithymia (difficulty in identifying emotions, describing emotions, and external thinking) (P< 0.01).

Findings reveal that treatment based on acceptance and commitment has been able to reduce the psychological problems of nurses with chronic low back pain. For this purpose, it is suggested that psychologists and pain specialists hold workshops and make plans for nurses with chronic low back pain.

Non-specific chronic low back pain (LBP) is the most common problem of spinal column disorder and musculoskeletal problems. Many evidence has demonstrated that exercise and corrective exercise is a positive intervention on decrease pain; but according to the relationship between increased lumbar lordosis angle and low back pain; it seems to be very important to implement the study about pain changes and lumbar lordosis angle. Furthermore, movement control impairment is one of the most problem related with low back pain. The aim of current systematic review was to evaluate the effect of exercise on pain, lumbar lordosis angle and movement control in participants with non-specific chronic low back pain.

A data base search within the all of times was performed, using Google Scholar, PubMed, The PEDro, CINAHL, Cochrane Library, Trip Database and Web of Science systems. Studies investigating the effect of types of exercise in pain, lumbar lordosis angle and movement control in patient with LBP were included. PEDro quality scale was used for the assessment of included studies.

Eleven out of 128 relevant articles had our search entrance criterions, which were chosen for this review (score higher than 5 on the PEDro scale). There was a large difference between various studies base on their methodology, outcome measures, simple size, procedure, etc. However, results from studies have verified that exercise causes decrease pain, decrease lumbar lordosis angle and increase movement control in patient with LBP; and exercise effective on decrease pain in pregnant women, but was not effect on lumbar lordosis angle in pregnant women. Also studies that shown decreased lumbar lordosis angle after exercises, was more effectively on more decreased LBP in patient.

It is likely that exercise decrease pain, lumbar lordosis angle and increase movement control in patient with low back pain; also exercise can decrease LBP in pregnant women, especially in the last months of pregnancy.
