Lumbar disc herniation is the most common specific cause of chronic low back pain and exercise therapy is one of the goals of its management. The aim of this study was to investigate the effect of core stability exercises on activation of abdominal muscles and flexibility of lumbar in men with disc herniation.

The subjects of this clinical trial study were 20 young and middle-aged men with lumbar disc herniation referred to physiotherapy in rasht in first half of year 1399 who were randomly divided into two groups of core stability exercises (n=10) and control (n=10). The electrical activity of the internal oblique, external oblique, and rectus abdominis muscles was measured by electromyography and abdominal muscle strength by straight leg raising test and flexibility by sit and reach test. Training protocol of intervention group included 8 weeks of core stability exercise, while the control group was only followed up. Statistical analysis was performed using paired t test an analysis of covariance test with SPSS software.

Activation of 3 muscles and strength and flexibility after 8 week of exercise had a significant improvement(p<0/05)but changes were not significant in control group. However, analysis of covariance showed a difference between two groups in activation of all three muscles and flexibility(p<0/05)But no significant difference was observed in muscle strength.

Our findings showed, people with disc herniation experience greater activation, strength, and flexibility in trunk muscles after core stability exercise thus can be considered in rehabilitation.

Low Back Pain (LBP) is one of the most common skeletal disorders, with an incidence possibility of up to 80% during one's life. Before planning a rehabilitation program, an accurate evaluation seems to be necessary in people with LBP. With regard to the kinetic chain of human body, any problem or dysfunction in any part of the chain can cause abnormal function in other parts. Abnormal hip kinematics and impaired hip muscle performance have been associated with LBP. So, the purpose of the current study was to compare electric activity ratio of gluteal muscles to tensor fascia lata in males with and without non-specific chronic LBP.
A total of 15 healthy males and 15 males with non-specific chronic LBP participated in the present semi-experimental study. Electromyography signals were obtained from the gluteus medius, superior gluteus maximus, and TFL muscles at 1000 Hz frequency as participants performed some selected exercises and the gluteal-to-TFL muscle activation indices were calculated. Repeated measures analysis of variance and independent t-test were run for data analysis.
The results of the present study demonstrated that, compared with the low back pain group, in launch, squat, hip abduction, clam in side lying, lateral step down, hip extension with extend knee, hip extension with flexed knee, one-side bridge, two-side bridge, and cutting maneuver with elastic resistance, gluteal muscles were significantly more active in healthy group (P The result of the present study shows that the electromyography activity index differs between the gluteal muscles and the tensor fascia lata in people with non-specific chronic LBP and healthy people. In order to plan rehabilitation exercise, the clam in side lying, cutting maneuver with resistance elastic, unilateral, and bilateral bridge exercises can be suggested to people with LBP, with the exception of lunch and squat exercises.

Patients with low back pain like other chronic diseases, may experience psychological symptoms in addition to physical symptoms which leads to the exacerbation of the condition of these patients and reduce their quality of life. Due to lack of clinical studies in this field, this study was conducted to investigate the relationship between pain and severity of depression and anxiety in patients with nonspecific chronic low back pain.
This analytic- descriptive study was performed on 250 patients with nonspecific low back pain referring to the orthopedic clinic in Shahrekord selected by convenience sampling. Demographic questionnaire, visual analogue scale of pain, Beck Depression Inventory and Beck Anxiety Inventory were used to collect the patient’s information, pain severity, anxiety and depression. Stata software 14 was used for data analysis.
Mean ± SD of pain in women was 4.6±1.21 and higher than in men (4.1±1.25). Pain severity showed a significant difference between the groups of patients with different levels of anxiety and depression (P Patients with nonspecific chronic low back pain experience higher level of pain with increasing severity of depression and anxiety. It is necessary in treatment of patients with nonspecific low back pain to pay attention to their psychological dimensions in addition to treating physical problems to reduce pain, and take action to relieve for the modulation of anxiety, depression and quality of life in these patients.

Musculoskeletal pain in mothers of children with Cerebral Palsy (CP) is significantly higher than that in mothers of typically normal children. The purpose of the present study was to evaluate the effect of eight weeks core stabilization exercises on trunk flexor and extensor musculature endurance as well as quality of life in mothers of children with CP.
In the current quasi experimental study, 30 mothers of children with CP who had low back pain, aged 6 to 18 years, were selected in Isfahan based on targeted and convenience sampling methods according to the criteria of the study. Next, they were randomly divided into two groups of experimental and control, each containing 15 mothers. The experimental group performed core stabilization exercises for 8 weeks, three days a week, each session lasting 20 minutes, while the control group did not do any regular exercise. Quality of life and trunk flexor and extensor musculature endurance were respectively measured using SF-36 questionnaire and trunk flexor and trunk extensor endurance tests prior to and after the eight weeks of exercise program.
Finding revealed significantl improvement in the quality of life (p=0.001), trunk flexor (p=0.002), and extensor musculature endurance (p=0.040) after implementing the core stabilization exercises intervention.
Based on the results, core stabilization exercise program can improve quality of life and trunk flexor and extensor musculature endurance in mothers of children with CP. Therefore, considering the importance of the health of mothers with CP children, their low levels of quality of life, and positive effect of core stability exercises on the quality of life and trunk muscle endurance, this exercise is recommended for mothers of children with Physical disability who have chronic low back pain.

Conservative treatment of patients with non-specific chronic low back pain (NCLBP); especially as exercise-based interventions, is a main part of rehabilitation program for such patients. This review study was designed to investigate the influences of exercise-based therapeutic intervention on patients with NCLBPin Persian studies. ISC, Magiran, IrMedex, SID, and MedLib were selected as searching motor engines by using keywords including NCLBP, exercise-based therapy, Therapeutic exercise, Exercise therapy, and Corrective exercise training. Studies which used patients with acute or specific low back pain as subjects were excluded from the review process.From 35 articlesfound, ten articlesincluded in ourstudy. They mainly concentrated on the effects of core stabilizing exercises and Pilates training on pain intensity, disability, function, balance, lumbar flexor and extensor muscles’ endurance, and electrical activity of abdominal and spinal muscles in individuals with NCLBP. Positive effect of core stabilizing exercises and Pilates training method on above-mentioned variables is confirmed in theliterature. Exercise-based therapeutic interventions; especially as core stabilizing exercises or Pilates training can lead to reducing pain and improving function in patients with NCLBP; although designing and implementing clinical trials studies is essential due to relative poor quality of present articles to achieve more valid results.

Regarding to high prevalence of low back pain (LBP) in athletes and its effect on their athletic function, an accurate evaluation before planning the rehabilitation program seems necessary in athletes with LBP. It should be considered that human movements are like as a kinetic chain. It means that any problems in every parts of this chain can cause dysfunction in the other parts of the chain. Not taking attention to the relationships between different parts of this chain may result in suboptimal rehabilitation. Therefore, focusing treatment on the entire parts of the kinetic chain besides the injured part, may prevent recurrenceof the dysfunction. Since in the kinetic chain hip muscles act as a link between lower extremities and trunk, the purpose of the present study was to evaluate and compare muscles strength of hip joint in female athletes with and without non-specific chronic LBP. Fifteen healthy female athletes and 15 female athletes with non-specific chronic LBP participated in this study. Their age was between 18-30 years. Hip extension, abduction and external rotation strength in all participants were measured. A hand-held dynamometer (HHD) was used to measure muscle strength. Since fixing HHD by examiner’s hand is fraught with error, it is fixed by a stable frame. The maximum strength value of hip extension and abduction in female athletes with LBP were significantly lower than these measures in healthy group (P < 0.05). No significant differences were seen in the maximum value of hip external rotation strength between two groups (P > 0.05). The results of the present study show that hip extension and abduction strength in female athletes with LBP were lower than these measures in healthy group. Therefore, hip strength measurements besides the examination of the spinal column seem to be necessary in evaluation and rehabilitation of the patients with LBP.

low back pain (LBP) is one of the most common and crucial health problems, which is difficult to treat and manage, causing an enormous economic burden on individuals, families, communities and governments. Walking as a usual and basic daily activity in order to have an independent life, is necessary. However, it seems that musculoskeletal sufferers like NCLBP patients spend more energy than normal individuals during walking. So, the purpose of this research is to evaluate energy consumption of patients with non-specific chronic low back pain during walking, compared with normal individuals this is a cross- sectional, case- control study, in which 2 groups of 16 (normal and patients) individuals participated in spring of 2013. Energy consumption was assessed during walking, based on the Physiological Cost Index (PCI), as a clinical tool. Difference between the mean values of walking speed and PCI was measured using two sample t-test amongst the participants. heart rate (HR) of normal individuals is significantly different from HR of those with NCLBP during resting and walking (P-value<0. 05). The mean value of walking speed of normal subjects was 76. 05 ± 5. 7 m/min compared to 69. 17 ± 7. 83 m/min in NCLBP patients (p-value = 0. 006). The PCI, measuring the difference between walking HR and resting HR in different walking speeds, was also significantly different between the two groups (0. 298 ± 0. 06 in normal individuals and 0. 388 ± 0. 098 in NCLBP patients). the results of this study showed that energy consumption of patients with NCLBP is more than that of the normal individuals due to insufficiency of heart muscular activity as a result of inactivity, or due to decrease in walking speed.

Comparison of global and local abdominal muscles thickness in chronic non- specific low back pain patients with healthy controls in position of hook-lying over variant stability surface utilizing diagnostic ultrasonography Methods and Materials: 20 chronic non-specific low back pain male patients compared with a convenient sample of age and gender matched healthy controls in a semi-experimental study. Thickness of abdominal muscles was measured in end of inspiration and expiration phases by B-mode linear ultrasound transducer in three different hook-lying positions over: 1- stable surface، 2- foam roller under spine and finally 3- foam roller under spine and one foot. Data were analyzed utilizing SPSS. In healthy controls internal oblique and transverse abdomens muscles in expiration phase revealed significant differences between three positions. P< 0. 001 In patients internal oblique and transverse abdomens muscles only revealed significant differences between position one and two. P< 0. 005 In low back pain subjects internal oblique and transverse abdomens muscles were unable to activate in more difficult position over unstable surface due to chronic pain process such as functional deficiency and decrease number of muscle spindle and muscle fiber atrophy.

Low back pain may cause clinical symptoms such as: reflex inhibition and atrophy of multifidus muscles، lumbar paraspinal muscles atrophy، dysfunction and disability. The atrophy of multifidus muscles could be a main cause of recurring back pain.. Therefore، present study compared the effect of stability and McKenzie exercises on pain، disability and multifidus size in women with chronic non-specific low back pain. 60 non-athletic women with chronic non-specific low back pain allocated in this research. They randomly and equally divided in to two experimental groups، 30 subjects (Mean ± SD age، 33. 37 ± 7. 92 year) in stabilization exercise group and 30 participants (Mean ± SD age، 37. 00 ± 9. 97 year) in McKenzie exercises group. Both groups performed exercise training for 6 weeks. The level of pain، disability، and the cross sectional area of lumbar multifidus muscle was respectively measured by visual analog scale (VAS)، Ostwestry disability index and Ultrasonography imaging. These data were collected just before intervention، after 6 weeks of exercise intervention، and also at the end of 4 weeks follow-up period. Independent sample t-test was used to analyze the data and P < 0. 05 was considered for statistical significance. Both exercises protocols may decrease pain and disability than before exercises (P < 0. 0001). The stabilization exercises may result in significant increase in L5 multifidus muscle’s size (P < 0. 0001)، while no significant change in multifidus size was observed after McKenzie exercises (P > 0. 05). Stabilization and McKenzie exercises may improve pain and disability in patients with chronic non-specific low back pain، while stabilization exercise results in size improvement of lumbar multifidus muscles at L5 level. Therefore stabilization exercises may be more effective to prevent recurrent chronic low back pain.

The purpose of this study is to compare the abdominal muscles thickness change at alteration in seated stability between healthy and non–specific chronic low back pain male subjects. In this case–control study, twenty non–specific chronic low back pain male patients whom had refered to physiotherapy clinics of university of Social Welfare and Rehabilitation Sciences and twenty healthy men were selected conveniently and simply. The thickness of Transverse Abdominis, Internal Oblique, External Oblique and Rectus Abdominis muscles of right side were measured with B mode ultrasonography (7. 5 MHz linear head) in supine lying (Position 1), relaxed sitting on a chair (Position 2), relaxed sitting on a gym ball (Position 3) and sitting on a gym ball lifting the left foot off the floor (Position 4). Measurement were taken at the end of both inspiration and expiration. Data were analyzied by Paired T and Independent T tests. Transverse Abdominis and Internal Oblique at all of position and Rectus Abdominis only at position 4 were thicker at the end of expiration in both healthy and patient groups (P<0.001). At the both status of inspiration and expirtion, there were significant differences in both groups in thickness change of Transvers Abdominis, Internal Oblique and Rectus Abdominis muscles between position 3 in comparison with position 2,position 4 with position 2 and position 4 with position 3 (P<0.001). Also there were significan differences in thickness change of External Oblique muscle between position 4 with position 2 and position 4 with position 3 in both groups (P<0.001). There were smaller increase in thickness of Transvers Abdominis in patients than healthy group (P<0.001) and smaller increase in thickness of Rectus Abdominis in healthy men than patient group (P=0.01). Abdominal muscles respond to postural changes and these muscles are automatically targeted by decreasing the seated stability. In non–specific chronic low back pain patients, activity of Transvers Abdominis was decreased and activity of Rectus Abdominis was increased.
