Introduction: Most people with multiple sclerosis are diagnosed with bilateral strength asymmetry in the lower limbs. Strength asymmetry increases muscle metabolic cost, muscle fatigability, postural instability, gait disturbance, imbalance, and risk of falling, and negatively affects the quality of life in PwMS. So far, the effects of rehabilitation exercises on reducing the asymmetric index in this population has not been studied convincingly. The purpose of this study was to investigate the effect of suspension exercise on bilateral isometric strength asymmetry of knee muscles in patients with multiple sclerosis. Materials & methods: In this randomized controlled trial, twenty-seven female patients were purposively selected as the statistical sample and randomly divided into the control (n = 13, age: 34.72 ± 5.01 years) and exercise (n = 14, age: 37.62 ± 4.58 years) groups. The control group received routine care while the exercise group received the suspension exercise protocol. Isometric muscle strength and bilateral asymmetry were measured at baseline and after 8 weeks. The Biodex isokinetic dynamometer was used to measure the maximal voluntary isometric contraction of the flexor and extensor muscles of the knee. The analysis of covariance was used to analyze the data. Results: The isometric strength of the knee extensor muscles in the weak leg at the angle of 20° and in both legs at the angle of 70° in the exercise group improved significantly. Furthermore, the strength of the knee flexor muscles in the exercise group was increased. The amount of bilateral strength asymmetry in the knee flexor and extensor muscles at the angle of 70° significantly decreased in the exercise group. Discussions & conclusions: These data suggest that suspension training is a practical approach to manage bilateral asymmetry in knee flexor and extensor muscle strength in patients with an EDSS of less than four. © 2024

Background: Parkinson's disease (PD) is one of the most common diseases of the central nervous system, primarily affecting the elderly. Its symptoms include tremors, slow movement, muscle stiffness (rigidity), and postural instability. This study aimed to investigate the effect of eight weeks of rebound therapy on balance and quality of life in people with PD. Methods: This was a quasi-experimental research study with pre-test and post-test. Among patients with PD, 24 individuals with severity levels 2 to 3 according to the Unified Parkinson Disease Rating Scale (UPDRS) were selected using convenience and judgmental sampling and randomly divided into two groups: a rebound therapy group (n=12) and a control group (n=12). The Parkinson's Disease Quality of Life Questionnaire (PDQL) was used to evaluate quality of life levels. The Single Leg Stance (SLS) and Y-Balance Test (YBT-LQ) were used to evaluate static and dynamic balance, respectively. Theintervention group performed eight week exercises (two one-hour weekly sessions Data were analyzed using repeated measures ANOVA at a significance level of 0.05. Results: The post-test quality of life scores in the rebound therapy group significantly higher than the pre-test scores, indicating an increase in quality of life (QoL) for patients (P≤0.05). Additionally, patients' static and dynamic balance in the rebound therapy group significantly improved from the pre-test to the post-test (P≤0.05). Conclusion: The results indicate that eight weeks of rebound therapy can effectively improve balance and quality of life in patients with PD. Therefore rebound therapy can be recommended as a complementary rehabilitation method in medical centers to enhance the health of PD patients. © 2024 The Authors. Published by JRSR.

Objectives The ability to safely walk up and down the stairs is an essential factor in older adults’ independence and quality of life. This study aims to investigate the effect of combined exercises on stair negotiation performance of older men. Methods & Materials In this randomized controlled clinical trial, 30 older men with at least 60 years of age living in Isfahan, Iran, in 2021 were selected who had functional independence, mental health, the ability to perform daily activities without using an assistive device, and without a history of falling. They assigned randomly to two parallel groups of intervention and control groups. Participants in the intervention group completed 12 weeks of combined exercise. The center of pressure (COP) parameters were measured by a force plate, and the time of stair ascending and descending was recorded by the Qualisys motion analysis system. The stair negotiation performance was evaluated by the timed up and down stairs (TUDS) test and the stair self-efficacy (SSE) scale. Data were analyzed by mixed ANOVA in SPSS software, version 24. The significance level was set at 0.05. Results The combined exercise program was effective in reducing the COP parameters during stairs ascending and descending (P<0.05). Stance time and time of ascending and descending decreased after the exercise (P≤0.034). The results of TUDS test (P≤0.002) and SSE scale (P≤0.048) showed improved performance in the intervention group compared to the control group. Conclusion The combined exercise program, by focusing on the factors such range of motion, strength, power, and balance, is effective in improving the stair negotiation performance of older men. Due to the prevalence of stair use in daily activities and its potential risk for older adults, this combined exercise program is recommended for older men. © (2023), (Negah Institute for Scientific Communication).

Background: Chronic ankle instability (CAI) is a common injury among athletes. Research has reported reduced dorsiflexion range of motion, impairment of proprioception, and decreased muscle strength of the ankle in people with CAI. The aim of this research was to examine the effects of 8-week core stability training on stable and unstable surfaces on ankle muscular strength, proprioception, and dorsiflexion range of motion (ROM) in athletes with CAI. Methods: Thirty-six athletes with CAI (age 22.42 ± 2.76 years; height 169.11 ± 3.52 cm; weight 68.46 ± 2.75 kg) participated in this study. They were divided into three groups: unstable-surface group (UG) (n = 12), stable-surface group (SG) (n = 12), and control group (CG) (n = 12). The UG and SG performed the core stability exercise protocol for 8 weeks, 3 sessions per week. The CG received their usual care and daily activities. Outcomes were measured pre-sessions and post-sessions. Results: The peak torque showed significant increases in the UG and SG compared with the CG during plantar flexion, dorsiflexion, inversion, and eversion (P < 0.05). There were also significant increases in UG compared with SG (P < 0.05). The proprioception showed significant decreases in UG compared with SG and CG (P < 0.05). The dorsiflexion ROM showed significant increases in UG and SG compared with CG. There were also significant increases in UG compared with SG (P < 0.05). Conclusions: It seems that core stability exercises on trampoline surface helps improve the measured parameters in athletes with ankle instability. Therefore, this type of training is recommended as a therapeutic option for Individuals with CAI. © 2023 Elsevier Ltd

Background and Aim: The aim of the study was to investigate the effect of selected exercises course on the scores of the Functional Movement Screening (FMS) test among the special unit staff of the Isfahan police force. Methods: The present study is quasi-experimental and prospective. The statistical sample of this research included 20 officers of the police special staff (NOPO) who were equally divided into two the experimental group (n = 10) and the control group (n = 10). Demographic characteristics of the special police force staff included mean age: 32.9 ± 2.68 years old, height: 176.80 ± 5.44 cm, and weight: 78.40 ± 8.84 kg. First, the subjects 'functional screening test scores were recorded, then they exercised for 8 weeks (3 sessions per week), and each session was allocated to one hour of selected exercises. Later, the subjects' functional screening test scores were recorded again. Due to the non-normality of the data, a non-parametric Wilcoxon test was used and the data were analyzed by SPSS software. Results: Eight weeks of selected exercises affected the FMS test score on four tests stepping over the obstacle (P = 0.008), launch (P = 0.009), stability push-ups (P = 0.046), and rotational stability (P = 0.015). However, it had no effect on four tests shoulder motion (P = 1.000), deep squat (P = 0.317), and active leg raising (P = 0.83), and the significance level in the present study was 0.05. Conclusion: The findings show that the selected exercises on the special police force staff are weak in the shoulder and squat movement pattern, and active leg raising, but have a positive impact on the pattern of stepping over the obstacle, launch, stability push-up, and rotational stability. Therefore, the functional movement screening test, as a method of injury prevention, are effective for the special police force staff. © 2022 Baqiyatallah University of Medical Sciences.

Background: Neuropathy control and management is an objective in therapeutic exercises prescribed for patients with Type 2 diabetic peripheral neuropathy. We examined the effects of 12-week integrated exercise (IE) on glycemic control and peripheral sensation criteria in patients with diabetic neuropathy. Methods: This study was carried out in 2019-2020 in Janan diabetic society of Najaf Abad in Iran. Based on MNSI scores, we assigned 40 patients into two equal paired random groups (control vs. IE). Pre and posttests were administered before and after three months of intervention. Results: Repeated measures ANOVA showed no significant interaction effect between the FBS of the groups (P = 0.26) but significant interaction effects were observed between the levels of 2 hrs pp G, 4 pm G, HbA1c, Diapason, Monofilament, and Thermofeel in favor of the IE group (P < 0.05). Conclusions: At the beginning of IE, we used massage and foam roller to release pain and improve blood circulation as well as sensation in the neuropathic areas. This may have helped the patients perform the aerobic and resistance exercises more easily. Therefore, better glycemic control and peripheral sensation were achieved. Verification of the long-term effects of this training strategy requires further study.

Purpose: Firefighters require a high level of functional fitness to operate safely, effectively, and efficiently. The authors studied the distribution of functional movement screen (FMS) scores in firefighters and examined whether an 8-week corrective exercise program based on National Academy of Sport Medicine guidelines could improve them. Methods: All 524 active firefighters of a city completed the baseline FMS testing. Those who obtained a score of 14 or less, a sign of movement dysfunction, and volunteered to continue their participation were randomly assigned to either an experimental (n = 51) or a control (n = 45) group. Both groups participated in an 8-week training program. The control group used their own usual training routine, but the experimental group used the specific protocol designed for the study. Results: The FMS scores of 43% of the population were less than 14. Repeated-measures analysis of variance revealed a significant interaction between FMS scores of the groups (F1,94 = 165, P < .001). The experimental group showed a 69% improvement from pretest (10.6) to posttest (17.8), whereas the control group showed only a 3% improvement from pretest (11.8) to posttest (12.1). Conclusions: Preceding studies have shown that FMS scores less than 14 increase the injury risk. The findings showed that using our proposed training protocol, low FMS scores could be improved to 14 and higher. Considering the high injury rate of firefighters, the authors suggest administering FMS periodically and to use a training protocol such as ours, to increase functional fitness and reduce injury risk. © 2020 Human Kinetics, Inc.

Introduction: Parkinson's disease (PD) is a chronic, progressive disorder that mainly affects the central nervous system and, consequently, the patient's functional status. This study aimed to compare the effect of 8-week rebound therapy-based exercise program and weight-supported exercises on the range of motion, proprioception, and the quality of life in patients with PD. Methods: Twenty patients were randomly divided into two equal groups of weight-bearing exercises and rebound exercise with no significant differences in age, weight, and height. The variables of the range of motion, proprioception, and the quality of life were assessed in pre- and posttest. Data were analyzed using repeated measure ANOVA and t-test at a significant level of P < 0.05. Results: All of the variables in the two groups were significantly improved after 8 weeks of exercise, whereas the improvement rate in the rebound therapy group was more than the weight-bearing exercises group in range of motion (134.60 ± 13.22 vs. 118.38 ± 12.48), proprioception (7.60 ± 3.22 vs. 10.38 ± 2.48), and the quality of life (147.60 ± 13.22 vs. 118.38 ± 12.48) of the patients (P < 0.001 for all variables). Conclusions: Given that both rebound and weight-supported exercises are effective on improving the range of motion, proprioception, and the quality of life of people with PD, it is recommended that the benefits of these exercises to be used in physical rehabilitation programs. However, rebound therapy exercises have had a greater effect on people with PD, and it seems better to use these exercises more than others. © 2019 International Journal of Preventive Medicine.

Background: To resolve the impairments associated with spinal cord injury (SCI), such as decreased balance, patients have been recommended to undergo various therapeutic strategies, including the use of different physical exercise methods. The aim of this study was to evaluate the efficiency of using rebound therapy (exercise on a trampoline) on SCI individuals' static stability. Methods: Sixteen people with SCI (American Spinal Cord Association classification: A = 6, B = 6, C = 2, and D = 2) were randomly assigned to an experimental (rebound exercise) group or a control group. The rebound therapy exercise program, lasting 12 weeks, was performed by means of a modified trampoline. During the said period, the experimental group received rebound therapy exercise for 10 to 30 minutes 3 sessions a week. Standing stability parameters (ie, excursion, velocity, and path length of the center of pressure in mediolateral and anteroposterior plane) were assessed before and after the exercise intervention by Kistler force plate (50 × 60 cm). Data were analyzed by repeated measures analysis of variance. Results: Significant interactions were observed for all 6 dependent variables except excursion of the center of pressure in mediolateral and the path length of center of pressure in anteroposterior plane (P < .01). This means that the control group had no progress, whereas the experimental group made a significant improvement in terms of static stability. Conclusion: The results of this study confirmed that rebound therapy could reinforce the static stability of individuals with SCI during motionless standing. It suggests that rebound exercise is a useful sports rehabilitation method for patients with SCI and other wheelchair-bound individuals. © 2019 Human Kinetics, Inc.

Background: Biomechanical factors are the main mechanism of load applied on the anterior cruciate ligament (ACL). The aim of this study was to evaluate the effect of eight weeks of core stability training on the lower extremity joints moment during a single leg drop landing task. Material and methods: Thirty basketball athletes were randomly assigned into training and control groups. The training group performed core stability training for 8 weeks, but the control group did not perform these exercises. Lower extremity kinetics and kinematics variables during a single leg drop landing test were collected by a motion analysis system and a force plate in a pre-and post-test. Data were analyzed using a mixed repeated measure ANOVA test (p ≤ 0.05). Results: The results showed there was a significant reduction in the moment of flexion, adduction and rotation of the hip and the moment of the knee and subtalar joint in the training group (p < 0.05), while there was no significant reduction in the ankle moment (p > 0.05). Conclusions: Core stability training that was used in this study can reduce the forces exerted on the lower extremity joints during single leg drop landing. So, this study provides evidence that core stability training reduces lower extremity joints moment and may reduce the risk of ACL injury in athletes. © 2019, Gdansk University of Physical Education and Sport.

Background and Aim: Patellofemoral pain syndrome (PFPS) is an orthopedic disorder of the knee joint which results in pain and impairment of performance. The purpose of this study was to investigate the effect of combined exercise (hip abductor and external rotators strengthening + balance) on pain and performance in the patients with PFPS. Materials and Methods: In this semi experimental study, 20 men with PFPS were selected by purposeful sampling and then randomly assigned to two groups, i.e. experimental (n=10) and control (n=10) groups. The experimental group performed a training program which consisted of hip abductor and external rotators strengthening and balance exercises, 3 sessions per week for eighth weeks. Pain and physical performance in the patients were assessed by Visual Analogue Scale (VAS) and WOMAC respectively, before and after exercise. Repeated measures ANOVA was used to analyze the data. P ≤0.05 was considered significant. Results: The results indicated that the changes and interactions of the two variables of pain (F=14/2 and p=0/001) and physical performance (F=60/2 and p=0/001) were significant in the experimental group (P < 0.05) after exercise. The results also showed that the experimental group, had reduced pain and showed a significant improvement in the physical performance (p<0/05), compared to the control group. Conclusion: Considering the effectiveness of training in the improvement of performance and reduction of pain, this training protocol can be useful in the physical rehabilitation of PFPs. © 2017, Kurdistan University of Medical Sciences.

BACKGROUND: Subjects with Spinal Cord Injury (SCI) should use various assistive devices to stand and walk. Unfortunately they suffer from slow walking speed, high energy consumption, and too much force applied on upper limb while walking. The aim of this study was to determine the gap between the gait performance of SCI and normal subjects to conclude how the performance of SCI can be improved. METHOD: Three groups of SCI walked with orthosis, SCI walked without orthosis, and normal subjects were recruited in this study. The normal subjects also walked with the same orthoses as SCI subjects. Some parameters such as ranges of motion of hip, knee and spatiotemporal gait parameters were evaluated by use of Qualysis motion analysis system. The difference between the gait parameters of three groups were evaluated by use of two sample t test. RESULTS: The mean values of hip joint range of motion of normal subjects while walking with and without orthosis were 48.3 ± 2.5 and 18.5 ± 8.8 degrees, respectively (p-value = 0.00). There was a significant difference between walking speed of normal subjects with and without orthosis. The walking speed of SCI subject with and without orthosis differed significantly. CONCLUSION: Although use of orthosis enable SCI subjects to stand and walk, but has some restrictions. As use of orthosis decreased the abilities of normal subjects it can be concluded that more attention should be done on design of orthosis and style of walking. © 2017-IOS Press and the authors.

Background and Aim: Mothers of children with cerebral palsy have a significantly higher prevalence rate of musculoskeletal pain than the mothers of normal children. The purpose of this study was to evaluate the effect of eight weeks of core stability exercises on pain and functional disability in the mothers of children with cerebral palsy. Materials and Methods: In this semi experimental study which was done in Isfahan, 30 mothers of children with cerebral palsy (age of children between 6 and 18 years), who had chronic non-specific low back pain were selected by convenience sampling method. They were randomly divided into experimental and control groups. Each group included 15 subjects. Experimental group performed core stabilization exercises for 8 weeks. The level of pain and functional disability were measured by visual analogue scale (VAS) and Oswestry Disability Index (ODI) questionnaire respectively before and after eight weeks of exercise program. Data were analyzed by repeated measure ANOVA (P = 0. 05). Results: Our findings showed significant effect of core stabilization exercises on the pain (P=0.001) and functional disability (P=0.001). Conclusion: Based on current results, core stabilization exercise program reduces pain and improves functional disability in mothers of children with cerebral palsy. Considering the positive effect of these exercises on pain and functional disability, this program could be recommended for people with similar problems. © 2016, Kurdistan University of Medical Sciences.

Aims: According to the role of exercise on the rate of occupational burnout, the purpose of this research was to compare occupational burnout among athletic and non-athletic military personnel in a military training center in order to evaluate the role of exercise on occupational burnout. Methods: In this descriptive - comparative research, 250 staff from an army training center in the Isfahan province, were selected as an available sample. In order to determine the level of occupational burnout and the rate of physical activity, the Jackson Maslach and Beck questionnaires were used. In the end, data were collected, and were analyzed using t-test as well as Pearson correlation and SPSS 17 software. Results: The most important finding in this study was that all the three dimensions of occupational burnout including emotional exhaustion, depersonalization and decreased personal achievements were lower in athletic military staff compared to the non-athletic staff. Conclusion: As a conclusion, findings reveal that sport and physical activities can increase human being capacity to cope with psychological pressures in the workplace. © 2015, Bagiatallah University of Medical Science.

Background & objectives: Enhanced muscle strength is seen when resistance exercise is combined with the consumption of nutritional supplements. Although there is a limited number of studies available about the efficacy of gamma oryzanol supplementation with resistance exercise in humans, but its usage as a nutritional supplement for strength is common in athletes. The aim of this study was to determine the effects of gamma oryzanol supplementation during 9-week resistance training on muscular strength and anthropometric measurements of young healthy males. Methods: In this double-blind clinical trial, changes of anthropometric measurements and muscular strength were studied after chronic resistance exercise and gamma oryzanol supplementation in 30 healthy volunteers (16 in supplement and 14 in placebo). Each day, gamma oryzanol supplement (600 mg) and placebo (the same amount of lactose) were consumed after training. The participants exercised with 80 per cent 1-Repetition Maximum (1-RM), for one hour and four days/week. Anthropometric measurements and subjects' 1-RM for muscular strength were determined at the commencement and end of the 9-week study. Results: There was no significant difference between the baseline characteristics and target variables at baseline between the two groups. After gamma oryzanol supplementation, there was no significant difference in the means of anthropometric and skin fold measurements between the supplement and placebo groups. However, there were significant differences between the supplement and placebo groups for 1-RM of bench press and leg curl, which showed that gamma oryzanol improved muscle strength following resistance training. Interpretation & conclusions: Our findings indicated that 600 mg/day gamma oryzanol supplementation during the 9-week resistance training did not change anthropometric and body measurements, but it increased muscular strength in young healthy males. Further, studies need to be done in trained athletes, women, and in patients who suffer from muscular fatigue.

Background: Determination of biological age is a crucial challenge in gerontology. We studied the profile of variations in physical fitness factors in three groups of active, moderately active, and inactive Iranian women. Finally, a formula was produced to estimate biological age of women based on their physical fitness measures. Methods: This ex-post facto research was conducted in 2010. After signing informed consent forms, 107 women from Isfahan (Iran) were selected by purposeful stratified sampling. The subjects aged 18- 65 years old and were categorized into age groups of 18-20, 21-25, 26-30, 31-35, 36-40, 41-45, 46-50, 51-55, 56-60, and 61-65 years old. From about 50 women who were asked to participate in each age group, at least 10 volunteers were evaluated. Physical fitness tests included vertical jump, modified pull-ups, sit and reach, Illinois agility test, 30-meter run, 20-meter shuttle run, sit-ups, and medicine ball throw. Statistical analyses were performed using SPSS16. Findings: Discriminant analysis revealed that 64% of physical fitness level was explained by physical activity level (P ≤ 0.01). Multiple regression analysis showed that chronological age had an inverse relationship with physical fitness factors. However, the rate of physical fitness reduction of subjects depended on their sporting activity level, i.e. higher sporting activity was associated with lower rate of physical fitness reduction. Conclusion: Similar to reports from developed countries, this study indicated that physical activity had positive effects on biological age. However, our subjects had lower levels of physical fitness. This study also provided a good opportunity to produce an equation to estimate biological age of Iranian women. Our findings are alarming, especially when considering aerobic fitness. This study could be more reliable, if the same data were collected from other provinces of the country.

Background: The aim of present research is to compare the effects of exercise therapy and physiotherapy that are two common treatments for pain and disability in patients with chronic low back pain. Methods: In this research 30 patients with chronic low back pain (history of low back pain for at least 3 months) were selected. Patients allocated in two treatment groups: exercise therapy (n = 17) and physiotherapy (n = 13). Disability was evaluated using oswestry low back pain disability questionnaire (ODQ) and pain intensity was evaluated with the visual analog scale (VAS).Two groups underwent treatment for 6 weeks. Post-test was performed at the end of treatment period. Following collection of primary information and determination of different variable, covariance test with the variety factor (pre-test) in the level of α < 0.05 was used to analyze the data. Findings: Research findings did not show statistical significant difference in pain (P > 0.05) but the difference in functional disability between two groups was significant (P < 0.03). Conclusion: Our results indicate that exercise therapy is better than physiotherapy for disability improvement in patients with low back pain. Finally, this study recommends that exercise therapy can be an effective modality to management patients with chronic low back pain.
