Patients and methods: Fifty-five subjects suffering from chronic neck pain participated in this randomized controlled study. They were randomly assigned to three groups; the DNF group, which was treated by traditional physical therapy (i.e., physical therapy agents, stretching, and isometric exercises), combined with DNF, and scapulothoracic exercises; the McKenzie group, treated by traditional physical therapy, combined with McKenzie exercises; and finally, a control group, treated by traditional physical therapy. Before and after 6 weeks of treatment, they were assessed for neck pain severity, cervical range of motion (ROM), and functional disability using a visual analog scale (VAS), a gravity-reference goniometer, and the Copenhagen neck functional disability scale (CNFDS), respectively. Results: Compared to baseline, all groups showed a significant decrease in neck pain severity and disability (p <0.05), and there was a significant increase in neck flexion/extension, lateral right flexion/left flexion, and right/left rotation ROMs (p<0.05). The improvement of the McKenzie group was significantly higher than the DNF group, and control group. Moreover, the improvement of the DNF group was significantly higher than the control group (p<0.05). Conclusions: The McKenzie exercises were better than DNF combined with scapulothoracic exercises to treat neck pain, functional disability, and mobility.

OBJECTIVE: To estimate the prevalence of LBP among academic teaching staff at King Abdulaziz University, as well as to identify its socio-demographic and work-related risk factors. METHODS: A cross-sectional study design was used to estimate the prevalence of LBP and the risk factors in 123 academic teaching staff members at King Abdulaziz University. Data on LBP history and disability using Oswestry Disability Index (ODI), work-related and socio-demographic characteristics of study participants were collected using a semi-structured questionnaire. The prevalence of low back pain data was analyzed using frequency and percentage descriptive statistics, and Chi-square was used to identify group differences. RESULTS: A total of 123 academic teaching staff with a mean age of 37.5 years old of whom 79 (64.2%) were females and 44 (35.8%) were males completed a self-administrative questionnaire. Using a self-rating scale, approximately a quarter of academic teaching staff had moderate disability 25.2%; 4.9% had a severe disability; only one subject 0.8% was crippled. There has been a significant relationship between the number of years of experience and the extent of low back disability (P < 0.05). The Chi-square test revealed 56.3% of takes part with 11–15 years of experience have moderate disability relative to those with 0–5 years of experience (11.1%). There was a trend towards significance among academic teaching staff for the effect of the faculty stream on low back disability (P = 0.077, Chi-square test revealed teaching staff in the medical stream had the highest percentage of participates with minimal disability (78.7%) whereas in the scientific stream had the lowest percentage of minimal disability (52%). CONCLUSION: The findings of this study have shown that there is a major problem of low back pain among academic staff at King Abdulaziz University and that the situation in other higher education institutions in Saudi Arabia is changing.

Objective: This study investigated the effect of exercise training and postural correction on disabilities of the arm, shoulder, and hand (DASH), hand grip and key pinch strength among smartphone users. Methods: One hundred university students were randomly divided into two groups; the experimental group participated in a 12-week programme of exercise training and postural corrections. The control group were instructed to follow their usual routine for smartphone utilization. Measurements of DASH scores, hand grip strength, and key pinch grip strength were conducted before and after 12 weeks for both groups. Results: There were no significant differences between the start values of both groups for DASH scores, hand grip strength, and key pinch strength (p > 0.05). However, there was a significant improvement in all outcomes measured in the experimental group (p < 0.05), with significant changes in the outcomes of the control group. Conclusion: Postural correction combined with a selected exercise training programme improved the hand grip, key pinch grip strength, and upper extremity disability and symptoms associated with smartphone use among university students.

Increasing anthropometric measures bring considerable spinal loads during sports practice, which inversely affects the adaptation abilities of the spinal structures; this in turn influences the spinal curvatures. The study was conducted to explore the relationship between anthropometric measures and sagittal spinal curvatures in handball players. Method. The total of 83 male handball players were divided into 2 groups, depending on their body height: group 1 (age, 23.62 ± 2.07 years) consisted of 40 handball players with height above average, group 2 (age, 24.63 ± 2.58 years) consisted of 43 handball players with height below average. The thoracic and lumbar curvatures and trunk height were measured with the Formetric III 4D spine and posture analysis system. Results. The thoracic kyphosis of group 1 was significantly higher than that of group 2 (p = 0.038), without a significant difference in lumbar lordosis (p = 0.312), and significant difference in the coefficient of compensation between thoracic kyphosis and lumbar lordosis (p = 0.026). Group 1 showed strong positive correlation between body height and kyphotic angle (r = 0.897), and moderate positive correlation with lordosis angle (r = 0.496). In group 2, there was weak positive correlation with kyphotic angle (r = 0.381), and weak negative correlation with lumbar lordosis angle (r =-0.355). Conclusions. Increasing body height of handball players is associated with bigger kyphotic and lordotic angles. Owing to frequent sagittal asymmetric overloading of the spine during handball training, exercises that help maintain good posture and correct the thoracic kyphosis are required, especially for taller players.

Office work is a sedentary role, which requires sitting for long durations, having a negative effect on spinal posture. Therefore, low back pain risk factors in office workers are different from other populations. The aim of this study was to examine the effect of lumbosacral joint angle on the lumbar mobility, functional disability, pain intensity and overall health in office workers with chronic low back pain. Methods A total of 116 male office workers with chronic low back pain (aged between 30–59 years) participated in this cross-sectional study. The lumbosacral radiography was used to divide the participants into two groups, according to the value of their lumbosacral joint angle: group A (lumbosacral joint angle <20°, n=61) and group B (lumbosacral joint angle group >20°, n=55). The lumbar mobility, functional disability, pain intensity and overall health issues of participants were measured. Results The functional disability and pain intensity of individuals in group A were significantly higher than group B (P<0.05). There was a significant decrease in the lumbar flexion and extension range of motion and activities of daily living of those in group A compared to group B (P<0.05). There was a significant increase in emotional health problems and impaired social activity of individuals in group A compared to group B (P<0.05). There were fair positive correlations between lumbosacral joint angle values and functional disability, pain intensity and social activity in office workers in group B (r=0.292, 0.036, 0.333 respectively). Conclusions A decreased lumbosacral joint angle increases functional disability and pain intensity, decreasing lumbar mobility and level of functionality. Furthermore, it reduces emotional health and social activity in participants with low back pain. Therefore, measuring the lumbosacral joint angle of patients with chronic low back pain during treatment may be useful to decrease their pain intensity and improve their functional disability and quality of life.

So, the aims of the study were to evaluate the strength of trunk muscles of soccer players suffering from osteitis pubis, and to compare the agonist/antagonist ratio of trunk muscles in osteitis pubis athletes with that of healthy athletes. MATERIALS AND METHODS: Twenty-five soccer male athletes with osteitis pubis, and 25 healthy soccer athletes. Peak torque/body weight (PT/BW) was recorded from trunk muscles during isokinetic concentric and eccentric contraction modes at a speed of 120 • /s for healthy and osteitis pubis soccer players. RESULTS: There was a significant decrease in concentric contraction of back muscles in osteitis pubis group (p = 0.01). A significant decrease in eccentric contraction of abdominal muscles was also recorded in osteitis pubis group (p = 0.008). Concentric abdominal/back muscles ratio was significantly higher in osteitis pubis group (p = 0.016), with no significant difference in eccentric abdominal/back muscles ratio between both groups (p > 0.05). CONCLUSION: Osteitis pubis group displayed concentric weakness of back muscle and eccentric weakness of abdominal muscles that lead to disturbance of the normal concentric abdominal/back ratio.

There is some recent evidence that temporal specificity is important for optimizing training for muscular performance. This study was to examine the long-term effects of static stretching performed at different times of day on hamstring torque and flexibility. Methods. The total of 60 trained male subjects with tight hamstring were selected and randomly divided into 3 equal groups. Group A received static stretch in the morning (07:00-9:00), group B in the afternoon (13:00-16:00), and group C in the evening (18:00-20:00). The hamstring isokinetic concentric and eccentric peak torque and knee extension range of motion were assessed before and after 6 weeks of static stretching (3 repetitions of 30 s, 5 times/week). Results. A statistically significant increase was observed in hamstring concentric and eccentric torque, and flexibility after static stretching at different times of day (p < 0.05). The concentric and eccentric torque post-training values were significantly higher than the pre-training values (p < 0.05). The hamstring flexibility post-training values of groups B and C were significantly higher than for group A (p < 0.05). The torque and flexibility change scores of groups B and C were significantly higher than for group A (p < 0.05), without any significant difference between groups B and C (p > 0.05). Conclusions. Afternoon and evening static stretching is more effective than morning stretching in improving the hamstring concentric and eccentric torque and flexibility. Therefore, static stretching is a time-dependent task and should be scheduled by clinicians, coaches, and athletes in the afternoon or evening.

Multiple stimulation parameters affect the force response of muscle, creating a large number of possible ES parameter protocols. Within the available literature no optimal setting has been identified. So the purpose of the study was to compare the efficacy of different ES protocols on the isometric peak torque of quadriceps femoris muscle and level of discomfort in patients with stroke. Materials and Methods: Forty male patients having hemiparesis post stroke were recruited for the study from the neurological outpatient clinics of Cairo University hospitals. Patients were randomly assigned into two equal groups. Group (A) received the frequency modulation protocol of ES while group (B) received the Pulse duration modulation protocol of ES. Isometric peak torque (IPT) was evaluated before and after treatment, also the level of discomfort was measured immediately post treatment by Visual Analogue Scale. Results: There was a significant difference between both groups post-treatment in IPT and level of discomfort as (P=0.0001). The percentage of improvement in the IPT post treatment was 47.2% for group (A) while for group (B) was 26.27%. Conclusion: Electrical stimulation protocol that used variable frequency is an effective stimulation strategy in improving muscle performance than traditional approaches that used constant frequency with variable pulse duration. While the pulse duration modulation protocol produced greater muscle comfort.

OBJECTIVE: The purpose of this study was to evaluate the effect of carrying a backpack on neck angles and ground reaction forces (GRFs) in children. METHODS: 3-D motion analysis system, with a force plate, was used to examine the effect of carrying backpack on neck angles and GRFs of thirty children with mean age (10.06 ± 1.31 years), mean weight (34.56 ± 6.9 kg), and mean height (138.63 ± 9.82 cm). The unloaded posture was compared with posture when carrying a backpack. The static test was used to assess the three angles of the neck, and the dynamic test was used to assess the GRFs. RESULTS: There were no significant differences in the craniohorizontal angle and shoulder sagittal posture between carrying backpack and without backpack (p = 0.153 and 0.272) respectively. There was a significant decrease in the craniovertebral angle in carrying backpack than without backpack (p = 0.032). There was a significant increase in GRFs values in carrying backpack than without backpack (p < 0.032). CONCLUSION: Carrying backpack with a load 7.5% of the child's body weight alters the head posture and GRFs values.

So, it is important to consider the patency of all the leg joints for stability during gait. Objective: To examine the effect of unilateral chronic ankle instability on kinematics and kinetics of trunk and lower extremity joints during shod walking. Materials and Methods: 3-D motion analysis system was used to record the gait kinematics and kinetics of trunk and hip joint of fifty subjects during shod walking (25 chronic ankle instability (CAI), and 25 healthy control group matched with CAI group in age, gender, and activity). Kinematic and kinetics pattern differences were established at 90%, zero%, 10% and 30% of gait cycle in the sagittal and frontal planes. Statistical analysis: Analysis of variance (ANOVA) was used to investigate the effect of unilateral chronic ankle instability on kinematics and kinetics of trunk and the lower extremity joints. The level of significant was set at 0.05 for all statistical tests. Results: Chronic ankle instability subjects were significantly (P< 0.05) more inverted in the frontal plane compared with controls in the entire studied parts of gait cycle. Subtalar joint motions are controlled by invertors moment compared with evertors moment in the controls. In addition to significant increase of ankle joint plantar flexion (P < 0.05), there was significant increase in ipsilateral hip joint adduction and lateral trunk lean towards the affected side. These proximal adaptations are significantly correlated to ankle adaptation in the same plane. Conclusion: Chronic ankle instability leads to kinematic and kinetic changes of trunk and hip caused by mechanical changes of ankle joint that should be considered during establishment of rehabilitation programs for persons suffering from chronic ankle instability.

Chronic ankle instability group consisted of 20 subjects their age average (21.4±5.55) years, height average (177.85 ± 4.96) cm and weight average (81.25 ± 6.87) kg, they were referred from orthopedic specialist. The control group consisted of 20 normal subjects, their age average (24.65 ± 4.61) years, height average (178.7 ± 3.76) cm and weight average (80.4 ± 12.43) kg. Participants walked on a treadmill at two speeds 5 km/h (comfortable walking) and 6.5 km/h (fast walking) for three min with resting period of twenty minutes between each test. Before testing there was 3 min warm up at 1.5 km/h, and after each test there was 3 min recovery at 1.5 km/h. The oxygen consumption and energy expenditure at the two speeds are measured by using ZAN 100 flow handy П medical device with a PC-connected to open spirometry system. Results revealed that there was a significant increase in oxygen consumption and energy expenditure of the two groups as walking speed increased from 5 to 6.5 km/h. There was no significant difference in oxygen consumption and energy expenditure between both groups at walking speed 5 km/h. However, the oxygen consumption and energy expenditure of chronic ankle instability group was significantly higher than control group at walking speed 6.5 km/h. So, chronic ankle instability increased the walking energy cost especially during fast walking.
