A Qualisys motion system capture with seven cameras and a Kistler force plate were used to record kinematics and kinetics variables of walking. The forces applied on knee, hip and L5-S1 joint contact forces (JCF) were calculated by using Open-SIM software. SPSS software was used to analyze data at an alpha set point of 0.05.Result: The propulsive and second peaks of ground reaction forces applied on sound leg were significantly higher than prosthetic leg (p<0.05). Although the forces applied on hip, knee and L5-S1 joint in the sound leg were higher compared to prosthetic leg, the interaction between side and joint factor was not significant (p>0.05).Conclusion: The results of this study showed that the meaningful JCF applied on the sound leg were more than that of prosthetic leg. Insignificant increases in JCF on the sound leg during life can create cumulative forces on knee and low-back and endanger these joints at the risk of knee OA and chronic low-back pain. Balanced forces applied on sound and prosthetic leg is important, if this is the case, so indicating using a proper usage of socket pin and prosthetic feet which may have beneficial impact on sound side loads.

One of the realities of movement which is important about humans is moving their hands to keep balance and reduce energy consumption while they are walking. Methods: In this context, the role of elbow joint and the limitation that the joint exerts in terms of movement on the forearm and arm as self-impact joint constraint is undeniable. This paper deals with modeling and control of humanoid robot’s hand as double-pendulum will consider mentioned constraint while normal walking and also in throwing darts. Results: The presence of the self-impact joint constraint contributed to about a 26% saving in power consumption of robot motors within an impact range of 0.6346 to 0.6896 during normal human walking.  Since this control has a high power, 10 to 30% of the uncertainty was added to the length and mass parameters. As was observed, this controller routed the desired curves in the least possible time. Conclusion: As mentioned earlier, consideration of this constraint in elbow joint of the humanoid robot will help in approaching the reality of system in comparison with past models previously designed. As constraint causes addition of severe nonlinear terms to dynamic system equation, the control of systems with this type of constraint faces a great deal of complexity. For adaptive-neural controller to control of the system of humanoid robot’s hand will be used. Also, to display the ability of control system, the uncertainty of length and mass for this system will be considered. The existence of self-impact joint constraint will cause saving in consumption power of robot engines within the impact range.

One of the common ways to reduce fatigue is passive recovering or using massage and cryotherapy after exercise. The present study aimed to compare the effects of massage and cryotherapy on muscles fatigue and isokinetic parameters.Methods:This study was conducted on54 healthy athletes aged 20-30 years who were randomly divided into three groups: cooling (ice therapy), massage, and control (resting). Each of the volunteers was evaluated in two sessions. The first session was to familiarize the participants with isokinetic contraction. The second session started with a brief warm up subsequently, using Biodex Isokinetic System Average Peak Torque (APTQ), Average Power (AP), and Total Work (TW) were measured. Then, the fatigue protocol was applied. Afterwards, interventions were performed for 15 minutes. After the intervention, isokinetic parameters were evaluated again. Also, perceived fatigue and Fatigue Index (FI) were recorded before and after the intervention.Results:APTQ, AP, and TW significantlyincreased in massage and cryotherapy groupsafter the intervention, while perceived fatigue and FI decreased significantly in both conditions (P<0.05). In the control group, however, no significant differences were observed in APTQ, AP, and TW before and after the intervention (P>0.05), but perceived fatigue and FI decreased significantly (P<0.05). Moreover, isokinetic variables (APTQ, AP, and TW) were higher in the massage group compared to cryotherapy and control groups (P<0.05), but such a difference was not observed between the massage and cryotherapy groups (P>0.05).Conclusion: Massage and cryotherapy could increase isokinetic parameters and decrease FI and perceived fatigue. Therefore, massage and cryotherapy have been more effective than rest as a strategy to return to normal state and no significant difference was observed between these two groups.

Lumbar pain during pregnancy can reduce the quality of life and using the pregnancy belts can improve it. Today, the most common design pattern of belts is in the form of an adjustable one-piece panel at the pelvic girdle and did not support the lumbar region. But the new pregnancy belt supports the lumbar and pelvic girdle simultaneously. The purpose of this study is evaluation of the quality of life of pregnant women with lumbar pain using the new pregnancy belt compared to the current belt.  Methods:  The total of 48 pregnant women with pregnancy-related lumbar pain participated in this randomized control trial study and were divided into three groups (current belt, new belt, and control group). All groups completed a demographic questionnaire and quality of life questionnaire (SF36) at the beginning of the study and after three weeks of follow-up. Results: All eight health concepts of the (SF36) questionnaire increased in both belt user groups but decreased in the control group after three weeks of follow-up. On physical health and mental health scales, there was a significant difference in the new belt group compared to the current belt group. Although there was no significant difference in the 2 variables (p=1.00, p=0.15, respectively). Conclusion: The new pregnancy belt can have a greater impact on enhancing the quality of life of pregnant women than the current belt.

The impairment of auditory processing results in communication, social and emotional problems in the life. Accordingly, in this study, communication abilities and speech perception in noise in CKD patients are analyzed to identify the disorders more rapidly. Methods: In this cross-sectional/comparative study, 30 CKD patients and 29 normal adults aged 20-55 years with normal peripheral hearing were randomly selected and the consonant-vowel (CV) test was performed with 5 signal-to-noise ratios (SNR) and silence, and speech, spatial and qualities of hearing scale questionnaire (SSQ) was applied to them with three subscales. The scores of the two groups were compared with the Mann-Whitney U test. Results: In both groups, the increase in noise led to a decrease in the consonant-vowel recognition scores. However, the normal group outperformed the patients at all levels. Patients in three subscales of the SSQ obtained a lower score than the normal group, but this difference was not statistically significant. Conclusions: The chronic renal failure reduces speech perception abilities in noise, and this finding indicates the auditory neurological involvement in CKD. Although the self-assessment by patients did not reveal any speech processing disability, for the early diagnose of hearing disability and mitigation of the consequences of hearing disability, it is recommended to periodically and regularly control the central hearing of patients and take proper rehabilitation measures if a disability is diagnosed.

However, ...  Read More Background: It has been recommended to use push-up for strengthening the scapular stabilizers and to use unstable surfaces for increasing the neuromuscular system involvement. However, the effect of this instability on the electromyography activity of the periscapular muscles during push-up in individuals with Scapular dyskinesis is not clear. Thus, the present study aimed to determine the effect of unstable surfaces on the electromyography activity of trapezius and Serratus anterior muscles in individuals with scapular dyskinesis during push-up. Methods: A systematic search was conducted in Web of Science, PubMed, and Scopus databases without time limit for start date until September 25, 2021. Using the search strategy, 5,249 articles were identified using the three main keyword categories, including Scapular dyskinesis, electromyography, and push-up. After reviewing the full text of the articles, four studies were included in the final review. Data extraction and methodological quality evaluation were conducted. For meta-analysis, the SMD and the 95% CI were obtained using CMA Software, Ver.3. P-value smaller than 0.05 was considered statistically significant. Results: According to the results, the use of unstable surfaces in individuals with scapular dyskinesis caused an increase in the activity of the upper trapezius (P= 0.011; SMD= 0.807 [95%CI 0.188, 1.427]) and a reduction in the activity of the Serratus anterior (P= 0.000; SMD= -0.665 [95%CI -1.023, -0.307]). However, it did not significantly affect the electromyography activity of the Lower trapezius (P= 0.176). Conclusion: Unstable surfaces should be used with higher caution in individuals with scapular dyskinesis because these people have an imbalance of the upper trapezius muscle compared to the serratus anterior muscle and incorrect use of unstable surfaces can cause exacerbation of muscle imbalance in these individuals.

This study aimed to investigate the effect of the Prevent Injury and Enhance Performance (PEP) program on knee valgus and knee flexion angles and Landing Error Scoring System (LESS) test scores in young male soccer players with poor landing mechanics. Methods: The present study was quasi-experimental. 47 soccer players with poor landing mechanics were purposefully recruited and they were randomly assigned to the intervention group (n=23 players, age= 12.69±0.70 years, height= 1.53±0.06 m, weight= 49.91±6.76 kg) and control group (n=24 players, age= 12.55±0.64 years, height= 1.51±0.08 m, weight= 51.25±7.73 kg). Knee Valgus angle, Knee flexion angle and LESS test scores were measured at the baseline and the end of the study. The intervention group used the PEP program as a warm-up for 8 weeks while the control group performed its routine warm-up during this time. ANCOVA and paired-sample t-test were used to evaluate changes. Results: The results obtained in the intervention group showed there was a significant reduction in knee valgus angle (p=0.001) and there were significant enhancements in knee flexion angle (p=0.003) and LESS test scores (p=0.001) but there were no significant differences in the control group in knee valgus and knee flexion angles (p>0.05) except for LESS test scores (p=0.001). Moreover, the outcome showed significant differences between groups in knee valgus angle (p=0.001), knee flexion angle (p=0.025) and LESS test scores (p=0.001). Conclusion: This study demonstrated that PEP program was effective in reducing dynamic knee valgus angles, increasing knee flexion angles and improving LESS test scores in young soccer players. Thus, it seems that this program can reduce the risk of ACL injuries in young male soccer players.

This study aimed to provide a Persian adaptation of the Pre-schoolers’ Conversational Skills scale a long with preliminary data on conversational skills in children with/out language disorders. Method: This study was designed to adapt an English research instrument into Persian version. The research team administered forward translation, synthesis of translations, backward translations, expert committee review, pretesting and cognitive interviewing, test of pre-final version, and submission and appraisal of all written reports to adapt the scale. The participants were four translators, a statistician, a linguist, a speech therapist, the research team, eleven language professionals, 10 mothers in cognitive interviewing and 114 mothers in pretesting final version of the adapted version. A test-retest approach was applied to evaluate the scale’s reliability. Results: There were not any complicated word or phrase during translations. The expert panel kept all items in the adapted version by adding examples to two items. The participants reported the Persian version items as clear and simple. The CVR and S-CVI were 1 and above 0.9 sequentially. The Cronbach’s alpha was equal to 0.9. The cut-off points of scale to categorize children were at or below 2.5, between 2.5 and 4.8, and at or above 4.8.   Conclusion: The adapted version of the Pre-schoolers’ Conversational Skills scale has excellent validity and highly reliable. It is easy, and quick tool to be administered in clinical settings. According to this scale, children can be categorized as “no or infrequent pragmatic skills”; “pragmatic skills are emerging” & “well-developed pragmatic skills”.

As parents of hearing-impaired children (HIC) experience high levels of stress and depression, this study sought to examine the effect of early intervention on the general health of parents of HIC.Method: A comparative cross-sectional study was conducted with parents of moderate to severe HIC who received either early or late intervention. The General Health Questionnaire (GHQ-28), which measures the four subscales of physical symptoms, anxiety, social dysfunction, and depression, was administered to both groups of parents. The independent t-test, an analysis of variance, and the tukey test were employed to compare general health and its subscales between the two groups.Results: A significant difference (Pv = 0.042) was found between the overall general health scores of parents (fathers and mothers) of HIC with early interventions and parents of HIC with late interventions, particularly on the social dysfunction subscale (Pv = 0.003). Mothers of children with late interventions exhibited greater disturbance on the GHQ’s social dysfunction subscale than did other  parents (Pv = <0.05).Conclusion: Early intervention enhances the general health of HIC’s parents, particularly in the social dysfunction subscale. The late intervention has a greater impact on the general health and social function of HIC mothers than on the  general health of other parents.

Some of these negative effects (such as child’s behavioral issues) could be eliminated by teaching mothers –as the main caregivers- to have proper skills. The present study investigated the effectiveness of teaching communication skills to the mothers of children with CP in reducing the children’s behavioral problems. Methods: Forty-two mothers who had 4-10-year-old children with CP, they were able to read and write, age between 20 and 40, and their children’s mobility score was at or below 3 in Gross Motor Function Classification System were recruited by convenient sampling. In this semi-experimental study, mothers completed the Rutter Children's Behavioral Questionnaire Children’s behavioral problems before and after the training. The experimental group received nine 90-minute training sessions on how to communicate with their children, the control group did not have any intervention regarding children’s behavioral problems.  Data were analyzed by Multivariate analysis of covariance (MANCOVA). Results: Comparing the two groups’ mean scores in five Rutter’s sub-tests showed significant differences (Aggression & hyperactivity, Social incompatibility, Anti-social behaviors, Anxiety & Depression, and General Behavioral problems) before the training indicated differences between groups (p =0.001). After training, the experimental group showed a significant reduction in five subtests of Rutter’s (p = 0.001). Conclusion: The present study indicated strengthening mothers with proper communication skills may change their interactions with their children with CP, and reduce the occurrence of a child’s behavioral problems. Therefore, rehabilitation team can consider the communication skills training program along with other therapeutic plans to intervene for children with CP.

Schedule for Oral-Motor Assessment – Persian (SOMA-P) has become one of the best methods for the assessment of swallowing disorders in the pediatric population. In this study, we evaluated the sensitivity, specificity, and consistency of SOMA-P by fluoroscopic barium swallows study. Methods: This is a descriptive-analytical study. SOMA-P was assessed on 52 children with swallowing problems. The children were 6 to 48 months and had been referred for a fluoroscopic barium swallow. We analyzed sensitivity; specificity, positive predictive value, and negative predictive value of SOMA-P, with the fluoroscopic barium swallow as the gold standard. For the evaluation of the correlations among variables, Cronbach's coefficient alpha was calculated. Results: In this study 6 parts of SOMA-P had 0-25% sensitivity, 90-97% specificity, 0-66% positive predictive value, 84-87% negative predictive value, 78-86% compatibility percent and 0.06-0.17 kappa value. Internal consistency was 0.93 using Cronbach's coefficient alpha. Conclusion: The results of this study suggest that SOMA-P is valid for the evaluating of swallowing disorders.  It can use as a screening test and as a complementary method to fluoroscopic barium swallow.

This study was conducted with the aim of the effect of priority and delay of the prone positioning and chest physiotherapy (CPT) in patients with covid-19. Methods: A randomized clinical trial was conducted on 26 patients with covid-19. Patients were randomly divided into two groups: The priority of the prone positioning over CPT (7 men and 6 women, with an average age of 67.46±5.91) and the priority of CPT over the prone positioning (8 men and 5 women, with an average age of 68.38±5.85). Respiratory outcomes including SpO2, PaO2, FiO2, FEV1, FVC, measured by the pulse oximetry, ABG, and spirometry, respectively, and FEV1/FVC, and SpO2/FiO2 ratios were assessed before and after the intervention. Results: The demographic characteristics of the patients and the respiratory outcomes at baseline between the two groups were not significantly different (P> 0.05). In each group, a significant difference was observed between the respiratory outcomes before and after the intervention (P< 0.05). But after the intervention, there was no significant difference between the two groups in respiratory outcomes (P> 0.05). Conclusion: Both the priority of the prone positioning over CPT and the priority of CPT over the prone positioning could improve each respiratory outcome. However, it was not observed that the priority or delay of the prone positioning and CPT can affect the improvement of respiratory outcomes in covid-19 patients.

One of the most important disorders that may occur in these patients and cause an increase in the disease burden is secondary complications. This study aimed to investigate the level of knowledge, attitude, and practice of patients with SCI on secondary complications.  Method: The current cross-sectional study assessed the knowledge, attitude, and practice (KAP) of patients with spinal cord injury about secondary complications. Patients with SCI were identified through the hospital information system. Data were collected through a questionnaire that included demographic and clinical information and a three-part questionnaire including knowledge, attitude, and practice. Results: one hundred eighty patients participated in the present study. The findings showed moderate level of knowledge, attitude, and practice with the mean respectively 84.12, 13.62, and 21.5 in patients with SCI. Conclusion: The level of knowledge, attitude, and practice of the patients trough potential complications of spinal cord injury, were moderate. There is a significant relationship between knowledge, attitude, and practice with education. Also, there is a significant relationship between knowledge and sex. There was no significant relationship between age with knowledge and practice, but there was a reverse relationship between age and attitude.

More than half of the children with CP experience various upper extremity problems with varying severity. Considering the importance of knowing the ability of children under 4 years old the aim of this study was to determine prepare Persian version mini-Manual Ability Classification System (mini-MACS) and evaluating its validity and reliability.Methods In a methodological study, after translation procedures, the face validity, content validity, test–retest reliability and interrater reliability of the Persian version of mini-MACS were evaluated. In total, 100 parents of children with cerebral palsy, 12 occupational therapists and a researcher participated in the evaluation of the scale’s reliability. Fifty six boys and 44 girls with cerebral palsy with an average age of 33.21 (SD=11.37) month participated in the study.Results The overall results indicated that the words and sentences used in mini-MACS were simple, clear, understandable, relevant and necessary. The ICC for test–retest reliability for parents, occupational therapists and researchers were 0.955, 0.979 and 0.943, respectively. The interrater reliability coefficient between parents and occupational therapists was 0.939, between parents and researcher was 0.954, and between occupational therapists and researcher was 0.922.Conclusion:The Persian version of mini-MACS seems to be valid and reliable. This system could be used to evaluate children with cerebral palsy.

The commonest feature of this disease is muscle weakness and impaired sensation in the extremities. However, various presentations can be observed in heterogeneous diseases included in this disease group, such as infection and ulcer in the foot. Case presentation: Here, in this case report study, we report an 18-year-old lady who was referred to us with a non-healing ulcer on the plantar surface of her right foot and was diagnosed with CMTD, based on the history of sensory and motor symptoms and the results of electromyography. Her ulcer healed successfully after five sessions of extracorporeal shock wave therapy (ESWT). Conclusion: Besides the significance of paying attention to patient’s symptoms for diagnosis of CMTD, this case presented the efficacy of ESWT on wound healing of a non-healing ulcer in the setting of CMTD. Further studies are required for verifying this treatment as the standard of care in such patients.

Methods: Twenty-five 25- to 54-year-old elite wheelchair basketball players with shoulder pain were randomly assigned to an exercise (n=13) or control (n=12) groups. The 8-week exercise program included strengthing exercises for serratus anterior, scapular retractor, and shoulder external rotator muscles and stretching exercises for upper trapezius, pectoralis major and minor muscles, and posterior glenohumeral capsule and underlying soft tissues. Shoulder pain intensity was measured using the wheelchair user's shoulder pain index and basketball performance using wheelchairs’ basketball skill tests. Shoulder internal and external rotation ROM, scapular upward rotation, maximal isometric muscle strength of middle and lower trapezius muscles, and pectoralis minor muscle length were also measured at baseline and after the 8-week exercise intervention. Results: Participants of exercise group experienced a lower level of shoulder pain (p=0.001) and a higher level of sport performance in all tests (p<0.05) compared with control group. In addition, shoulder internal and external rotation ROM (p>0.001) and external rotators muscle strength (p<0.001) and middle and lower trapezius muscle strength (p=0.003 and p=0.004, respectively) were improved significantly in the exercise group than control group. Scapular upward rotation (p<0.001) and pectoralis minor length(p<0.001) were also increased significantly in the exercise group than control group (p<0.05). Conclusions: An eight-week exercise program that targeted scapular stabilizers and rotator cuff muscles can improve glenohumeral internal rotation, pectoralis minor length, and lower Trapezius muscle strength, therefore can be a viable option for shoulder pain relief and enhancing sport performance in wheelchair basketball players.

This study aimed to investigate the effect of early retirement from sports injuries on the physical condition, quality of life and health, self-esteem, and body-esteem of active and inactive Iranian elite athletes. Methods: This cross sectional study was conducted on fourty elite retired Iranian athletes, mainly ski, wrestling, and mountaineering, with an average age of 66. 62±4.65 years, height 166. 70 ±3.66cm, weight 66. 15± 4. 88 kg . participated were divided into two active groups (n = 20) and inactive (n = 20) based on the current type of sports activity. The Nordic, SF-36, Rosenberg, and Mendelson questionnaires were used to determine musculoskeletal pain, quality of life, self-esteem, and Body Image. Results: The results in the active and inactive groups showed that the participants in the active group reported a higher score in terms of quality of life compared to the inactive group (P = 0.001). Also, in body image (P = 0.001) and self-esteem (P = 0.001), the active group reported more points than the inactive group, which was statistically significant. Conclusion: According to the study's results, it is suggested that sports health and psychology experts pay more attention to the post-exercise period of elites and recommend that elite sports retirees continue light sports activities as much after doing professional sports.

Methods: In this cross-sectional study, 15 healthy individuals walked with their self-selected speed in level ground with zero slope and two inclined surfaces constructed according to real environments with +8 (uphill) and -8 (downhill) slopes along 8 m. Measured variables included angles of sagittal plane of ankle, knee, and hip joints in different phases of gait through a three-dimensional motion capture system. Results: Significant differences were seen in uphill walking compared to level-ground walking with their increase in ankle, hip, and knee angles in initial contact, maximum ankle dorsiflexion and plantarflexion, maximum knee flexion in stance phase, and maximum knee extension in swing phase, and also with their reduction in maximum angle of knee flexion in swing along with maximum extension of hip joint (P<0.05). In downhill walking compared to level ground, significant differences were observed for increase of ankle and knee angles at initial contact, maximum ankle dorsiflexion and plantarflexion, maximum knee flexion in stance and swing phases, maximum knee extension in swing, and also decrease of hip extension maximum angle. No significant difference was observed in hip joint angle at initial contact between level and downhill surfaces (P>0.05). Conclusion: Walking on inclined surfaces clearly affects flexion and extension angles of lower limb joints in different phases of gait, requiring greater movement of joints. These changes are more obvious in uphill than downhill, particularly at initial contact.
