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.

The aim ofthis study was to determine the effectiveness of the limited dynamic wrist splinton the symptoms, function, and strength of women with CTS. In this controlledtrial study, the subjects wore a splint of a new design called the “limited dynamicwrist splint”, which allowed the wrist motion in the range (between 15-degreeflexion and 15-degree extension) that exerts minimum pressure on the mediannerve and prevents extra pressure on the nerve by limiting the range of motionsout of the allowed range.Methods: In this study, 24 women diagnosed with mild to moderate CTS wereinitially evaluated on the basis of the Boston questionnaire, the dexterity testof the Purdue pegboard, grip and pinch strength, distal sensory latency, andsensory nerve conduction velocity. The subjects were randomly divided intotwo groups, control and treatment. Both groups received routine rehabilitationtreatment for six weeks. The treatment group received the limited dynamic wristsplint for about six to eight hours a day. After six weeks, the initial examinationswere repeated. The SPSS-16, independent t, and paired t-tests were used for dataanalysis.Results: All the variables in the treatment and the control groups showedimprovement. The function test of the Boston questionnaire, the Purduepegboard test, and the pinch strength were significantly improved in thetreatment group. The “severity of the symptoms” test of the Boston questionnaireand the pinch strength in the control group showed a statistically significantdifference (P < 0.05). In a comparison of the two groups, the function test of theBoston questionnaire showed a significant difference.Conclusion: This study showed that the use of the limited dynamic wrist splintfor about six weeks for six to eight hours a day could have a significant effect onthe function, dexterity, and the pinch strength of patients with CTS. Not onlycan the patients receive treatment by this method, but they can also performtheir daily activities to some extent.

Although some studies have been performed on the effect of scoliosis on the respiratory system, there are still some ambiguities at issue and some results are contradictory. The aim of the present systematic review study was to help clarify the effect of scoliosis on the respiratory system and the factors affecting respiration. Methods: An electronic search was done in databases including PubMed, Web of Science, Ebsco, and Science Direct. The quality of papers was assessed using Black and Down instrument. The following keywords were used in search engines; adolescent idiopathic scoliosis, respiratory function, respiratory problem, respiratory system, ventilatory function, ventilatory problem, ventilatory system, chest wall motion, respiratory muscle, and exercise capacity. Papers in English language, subjects being over the age of 10 and suffering from adolescent idiopathic scoliosis, and no other abnormalities were among the inclusion criteria, while suffering any underlying disease was an exclusion criterion. Results: Based on the keywords used, 76 papers were found; based on the inclusion and exclusion criteria, 7 papers were approved. Five papers had dealt with pulmonary and respiratory factors, two investigating respiratory muscles, 2 examined exercise capacity, and 2 tested the chest wall motions. The score of reporting, external validity, internal validity bias, internal validity - confounding (selection bias), and power varied within 5-7, 0-2, 2-4, 0-3, and 2-5, respectively. Conclusion: Based on studies carried out so far, scoliosis affects respiratory function including respiratory volumes, chest wall motions, strength of respiratory muscles, respiratory patterns, and respiratory function during exercise. Although some studies show contradictory results, relying on the results of the majority of studies, it can be stated that these effects had been mentioned as negative effects on the mentioned factors. The reasons stated for the results include mechanical insufficiency and muscular disorders, which arise from developmental and systemic disorders associated with scoliosis itself. The relationships between respiratory volumes, strength of respiratory muscles, and chest wall motions are still unclear. Since only limited studies have been performed in this regard, these results still warrant further investigation.

The mainaim of rehabilitation is to increase the participation of stroke patients in differentareas of life. The current study purposed to review the factors influencing theparticipation of Iranian stroke patients in life areas.Methods: Databases including ISI-Web of Knowledge, PubMed, Google Scholar,and Scopus were searched using keywords such as occupational therapy,participation, activities of daily living (ADL), instrumental activities of dailyliving (IADLs), work, play, leisure, education, social participation, sleep, andrest in combination with Iranian stroke patients and CVA. The quality of thestudies was evaluated using the PEDro scale. All papers reviewed in this studyconcerned factors influencing the participation of Iranian stroke patients andwere published from 2000-2020.Results: In total, 178 articles were identified as eligible for an Iranian strokestudy. Of these, 104 articles were discarded, and an additional 38 were removedbecause of repetition and duplication. After careful evaluation of the papers, 34were selected for final analysis. Most of the included studies concerned the ADLarea of participation (N=32), and the lowest number of articles were in the areasof play (N=1), sleep/rest (N=2), and health management (N=3).Conclusion: In Iran, researchers have not paid enough attention to theparticipation of stroke patients in areas of life. Most studies focus mainly onpatient’s performance components, such as sensory and motor skills.

However, it is not clear whether the improvement in jump height is due to the enhancement of joint power or due to other mechanisms such as neural adaptations.Methods: To investigate this dichotomy, we tested the acute neuromechanical changes following a preloaded exercise protocol (3 sets of 5 consecutive CMJs with a weighed vest equal to 15% of the body mass of the participant) that successfully increased the subsequent jump height. On average, jump height increased 1.52 cm (5.4%) after this exercise as compared to CMJs prior to the exercise protocol.Results: A significant decrease in the time from the start of the movement to take off (pre-take off duration) was observed. This decrease was exclusively caused by exercising with a weighted vest, since such a change was not observed in the control sessions in which participants exercised without the weighted vest. Our data showed that jumpers leave the ground with some degrees of knee flexion and upon exercising with weighted vest this amount of flexion increased and hence an increase in the jump height. However, no significant changes in peak values of lower limb joint angle, velocity, moment and power were observed.Conclusion: It is suggested that for designing weighted vest exercise protocols with the aim of increasing jump height, the idea of modifying the timing of the movement should be considered as a cause of the enhancement. This novel idea adds another mechanism for increasing the jump height following weighted vest exercise, along with the general belief of muscle potentiation..

The aim of this study was to investigate the firing pattern of the main muscles involved in sit-to-stand (STD) and stand-to-sit (STS) tasks in two prevalent LBP subgroups based on movement system impairment (MSI) classification. Methods: A total of 37 women between 18 and 50 years of age voluntarily participated in this cross-sectional study. They were divided into three groups (15 healthy, 15 lumbar extension rotation syndrome (LERS), and seven lumbar flexion rotation syndrome (LFRS)). Surface electromyography was recorded bilaterally from the trunk stabilizer muscles—i.e. the internal oblique (IO), lumbar erector spine (ES), and hip mobilizer muscles—and the medial (MH) and lateral (LH) hamstring muscles during STD and STS tasks. The variations in EMG onset muscle timing and asymmetry in side-to-side muscle timing were measured. Results: The firing sequence during the STD task showed no significant difference among groups. However, in the healthy and LFR groups the trunk stabilizer muscles were activated before the hip mobilizer muscles, and in the LERS group an insignificant delay was shown in the onset of the ES activity. There was no significant difference of bilateral muscle timing during STD. In the STS task no consistent order of pattern was found even in the healthy group. The bilateral muscle timing of IO (mean difference, -427.00; P=0.021) and ES (mean difference, 1964.57; P=0.000) had significant difference in the LFRS group during STS. Conclusion: The cumulative effects of recruitment pattern impairment may contribute to continuing the cycle of lumbar movement impairments and subsequent persistence of LBP.

Increase in anterior cervical convexity and anterior displacement of the line of gravity of head in individuals with FHP is assumed to result in altered moment arms and muscle activity on cervical spine. Measurement of muscle thickness seems to be an appropriate index for muscle activity. This study was aimed to compare cervical extensor muscle thickness in individuals with normal head posture with those suffering from FHP.Methods: Twenty volunteers with FHP and 20 matched controls (11 females and 9 males in each group) participated in this cross-sectional study. The thickness of cervical extensor muscles including multifidus, semispinalis cervicis, semispinalis capitis, splenius capitis and upper trapezius were measured using ultrasonography at the level of forth cervical vertebrae at rest.Results: No significant differences of thickness of cervical extensor muscles were observed between the two groups (p<0.05) at of rest.Conclusion: The results of this study showed that the thickness of cervical extensor muscles at the level of forth cervical vertebrae in individuals with FHP did not change in comparison with normal head posture at rest. Further studies are recommended to evaluate extensor muscles at other levels of cervical spine.

However, there are no reports on the effect of fatigue protocol and its level on musculotendinous stiffness (MTS) of the tricep-surae. This study was designed to compare the effects of 2 levels of submaximal fatigue contraction on MTS of triceps-surae.Methods: Twenty female students by simple randomized sampling participated in this study. Triceps-surae musculotendinous stiffness was measured before and after two fatigue protocols. The fatigue protocols were comprised of a continuous isometric voluntary plantar flexion contraction (25% and 70% maximum voluntary contraction) until the contraction could no longer be maintained. The free oscillation technique was used to measure MTS of the triceps-surae. A Kistler force plate was used to measure the force applied.Results: Musculotendinous stiffness decreased immediately after both fatigue protocols (P value ≤ 0.05). Data analysis with RM ANOVA showed that there was no significant difference between the two protocols with respect to the decrease in MTS stiffness of the triceps-surae. Moreover, the decrease in stiffness did not change for 15 min after the two fatigue protocols (P>0.05).Conclusion: Musculotendinous stiffness of the triceps-surae decreased significantly after both fatigue protocols, and there was no significant difference between the two protocols with respect to change in triceps-surae musculotendinous stiffness. This result may be due to similar type of contraction in protocols, the learning effect, or the effect of central fatigue.

Patellar kinesio taping may have different effects on short and long term usage. The aim of this study is to compare the effect of short term and long term patellar kinesio taping in patellar position on women with patellofemoral pain syndrome using Magnetic Resonance Imaging (MRI).Methods: Thirty women with a mean age of 32.2 ± 6.18 years with one year history of PFPS participated in this study. All participants provided written, informed consent. MRI was taken three times from participant’s patellofemoral joint: 1) Without taping, 2) Immediately after taping in the first session, 3) After 10 sessions of taping. The effectiveness of the interventions was determined by measuring the patellofemoral congruence angle (PFCA), lateral patellofemoral angle (LPFA), and lateral patellar displacement (LPD) on MRI images.Results: Statistical analysis showed that utilizing kinesio taping in short time and after 10 sessions, significantly changed PFCA and LPD – except for PFCA after 10 sessions. Moreover, taping didn’t have any significant effect to alter LPFA.Conclusion: In short term, mechanical effects of kinesio taping influenced the patella position but in long term, neuromuscular effects may be more effective than each one separately to alter patella position.

The aim of this study was to investigate the normal range andchanges process of lumbar curve in students, both girls and boys, in the agegroup of 10 to 18 years.Methods: A total number of 1800 students (male and female), in the age group of10 to 18 years were selected to participate in the present study. The student sampleswere chosen from the different cities of the Isfahan province in a randomizedand clustered manner. Each age category included 100 male and female studentseach. The flexible ruler was used to measure the lumbar curve angle. The factorialANOVA method, in SPPS16, was used for data analysis with α=0.05.Results: The data analysis showed that the age changes factor and gender factorhave a significant effect on lumbar curve changes in the level of P<0.05. However,the interaction between gender and age was not significant (P>0.05). This meansthat the changes process is similar in both gender groups.Conclusion: The lumbar curve angle is generally higher in girls. Moreover, thisangle increases in both genders as age increases to 18 years. The extent of thelumbar curve exceeds the normal limit in girls after 13 years of age with the onsetof puberty, which means that girls in this age group need additional attentionfrom the concerned authorities in order to prevent spinal abnormalities.

Sub-acromial impingement syndrome (SIS) is one of the most common causes of shoulder pain affecting shoulder joint range of motion. The purpose of this study was to compare shoulder joint functional range of motion in overhead athletes with and without Shoulder impingement syndrome. Methods: The current research is a cross-sectional study, in which 63 male overhead athletes (30 subjects without impingement syndrome (age: 28.12±6.13 y/o) and 33 subjects with impingement syndrome (age: 26.83±4.81 y/o)) threw a handball ball three times, while seating on a chair. A 6-camera Vicon Motion Capture system recorded the markers placed on the upper limb and trunk during each of the throwing conditions. To evaluate the range of motion, a whole-body kinematic model was used in OpenSim software, with inverse kinematics used to obtain adequate joint angles (shoulder joint abduction as well as internal and external rotation). Results: The results indicated that the external rotation and abduction range of motion were greater in the athletes with shoulder impingement syndrome in comparison to those without impingement syndrome (P <0/001 and p= 0.04, respectively), while their internal rotation range of motion were more limited than that of athletes without impingement syndrome (p<0/001). Conclusion: Overhead athletes with impingement syndrome have greater glenohumeral external rotation and abduction and less internal rotation in the throwing shoulder in comparison to athletes without impingement syndrome. These findings can be used to screen and identify high-risk athletes and help the therapists to make more appropriate therapeutic plans in order to assist the injured athlete to return to sports as soon as possible.

Purdue Pegboard, Box and Block, and Finger to Nose tests were used to measure dexterity (fine and gross) and coordination performance of the stroke group compared with the same hand of the healthy group. The Barthel index was also used to assess disability or dependency of stroke patients in basic activities of daily living.Results: Results showed that stroke individuals with involvement of ipsilateral hand had less coordination and dexterity when compared to the same hand of normal subjects (P=0.001). In addition, the relationship of gross and fine manual dexterity performance of the ipsilateral upper extremity with disability, including dependence in basic activities of daily living, were significant respectively (r=0.376, r= 0.391).Conclusion: People with right stroke had significant ipsilateral upper extremity impairments (manual dexterity and coordination tasks), and this hand dexterity deterioration had an impact on their dependence in basic activities of daily living.

Dueto high loading forces during weight-bearing activities, the knee joint is prone to degenerative processes. This study aimed to compare the flexibility of muscles around the knee joint in patients with knee osteoarthritis with those of healthy individuals.Methods: Twenty-three women with bilateral knee osteoarthritis and 23 healthy women matched with the patient group for age, height and weight participated in this study. Flexibility of the quadriceps, hamstring, iliotibial band, adductor and gastrocnemius muscles was evaluated with a goniometric device. Pain intensity was assessed with a visual analogue scale. The data were analyzed with independent t-tests to compare the two groups, and Pearson correlation coefficient was calculated to correlate muscle flexibility and pain intensity.Results: significant lower flexibility of the bilateral quadriceps muscles was found in patients compared to healthy women (P<0.05). No significant differences were detected between groups regarding other muscles. Quadriceps flexibility correlated significantly with pain intensity in patients (P<0.001).Conclusion: In patients with osteoarthritis, quadriceps flexibility may be decreased although other muscles may remain unaffected. Quadriceps stretching is thus a potentially important component of treatment, which may influence pain reduction in these patients.

The aims of this study were: 1) reliability assessment of smartphone accelerometer for trunk accelerometry; 2) comparison of stability indices base on trunk accelerometry between the amputee and able-bodied subjects; and 3) comparison between energy storage and release (ESR) and multi-axis prosthetic feet users. Methods: Eleven below-knee amputees (5 multi-axis and 6 ESR prosthetic feet) and 11 able-bodied subjects enrolled in this comparative study. The dynamic stability was assessed using a smartphone attached to their back through an elastic belt during walking in a 6-m walkway. Also, normalized root mean squares (nRMS) of mediolateral (ML) and anteroposterior (AP) directions were calculated as stability indices. The intraclass correlation coefficient (ICC), standard error of measurement (SEM), SEM%, and Bland-Altman plots were used for reliability analysis. The Independent T-test was also used to compare the healthy and amputee subjects as well as ESR and multiaxis prosthetic feet users. The critical alpha was set at 0.05. Results: The results showed that the accelerometer has the ICC values more than 0.97 and 0.89 for test-retest and inter-session, respectively. Amputees had significantly higher trunk accelerations in ML direction compared to able-bodied subjects (p=0.023) but not in AP direction (p=0.496). Although the results were not significant between ESR and multi-axis prosthetic feet (AP P= 0.16, ML P=0.44), the AP stability index was higher in ESR users (AP Multi-axis=117.45, ESR=127.38). Conclusion: The smartphone can be used as a reliable measurement tool in clinical environments to assess the stability indices based on trunk accelerometry in transtibial amputees. More studies should be conducted to obtain more reliable results.

Different tests have been developed for diagnosis and quantification of reduced ability of speech perception in noise and the Quick Speech-in-Noise test is one of the most appropriate of them. The goal of the present study was to develop and validate the Persian version of the Quick Speech-in-Noise Test in normal, Persian speaking, 18-25 year-old participants.Methods: This study had two main stages: first, developing the test materials and determining the content validity and the second, determining the equivalency of the test material lists, and assessing the reliability of them.In the first stage, sentences having content validity were developed and recorded. In the second stage,in order to determine list equivalency, the lists were presented to 60 Persian-speaking (gender balanced), 18-25 year-old students and the average SNR-50 for each list was calculated using the Spearman-Kärber formula. In order to determine the reliability of the test, the test was again administered to15of the primary participants, two weeks later.Results: among80 sentences developed, 60 received enough credits from audiologists and speech therapists. Average SNR-50 in the Persian language was calculated as -0.25 dB. Thirty six content valid sentences, according to special criteria, were divided into six lists each containing 6sentences. The SNR-50 for each list revealed that lists number 2,3, 4and 5 were equivalent. Examination of test-retest reliability indicated that lists number 1,2,3,4 and 6 were reliable (P<0.05).Conclusion: Present study was developing three equivalent and reliable lists (number 2,3,4) for the Persian version of the Q-SIN test which are useful for diagnosing and selecting the best rehabilitation method for people with reduced speech perception in noise.

Therefore, ...  Read More Background: Lateral epicondylitis, or tennis elbow, is one of the common disorders in humans. Despite recommended treatments, there is no definite therapy for this disorder. Therefore, the aim of this paper is to review scientific reports on the effects of orthotic devices for treatment (comparing orthoses with other treatments related to lateral epicondylitis parameters), reducing complications, and improving symptoms of this condition. Methods: Ovid, Scopus, and Web of science were searched to identify studies which reported the effectiveness of orthotic treatment for lateral epicondylitis from 1996 until 2017. Studies were collected based on the inclusion criteria and a few were selected out of a large number of studies. The PEDro scale was used for the quality assessment of the selected articles. Results: A total of 43 articles were chosen, 16 articles on Orthotics vs. other nonsurgical treatments, 20 articles on the comparison of different orthotics, and 7 reviews. Conclusion: Based on the results of the selected papers, there was not sufficient evidence to decide on the effectiveness among several orthoses or for comparing orthotic treatment with other treatment methods. However, it should be emphasized that the use of orthosis can be an acceptable treatment for improving some symptoms of this condition such as pain, grip, pain-free grip, no pain, grip strength, function, ROM, and proprioception.

Methods: In this experimental randomized clinical trial, 45 female college students with upper crossed syndrome voluntarily participated and were randomly divided into three equal subgroups including shoulder girdle group, pelvic girdle group and combined group. The three groups performed corrective exercises of eight weeks and three times per week. The maximal voluntary ventilation was assessed before and after intervention. Results: The results showed that the main effect of group was significant (P = 0.029). The Least Significant Difference (LSD) post-hoc test demonstrated significant differences between combined groups with shoulder girdle group (P = 0.048) and pelvic girdle group (P = 0.011), but no significant differences between shoulder and pelvic groups (P = 0.537). The results showed a greater maximal voluntary ventilation in the combined exercise group than in the other groups. The main effect of time was significant for the three groups (P = 0.000). There was a significant interaction of groups by time for outcome measurement (P = 0.000). Conclusion: The results of this study provided preliminary guidance for the use of the comprehensive corrective exercises for simultaneous correction of anomalies.

It has been reported that abdominal musclesendurance can be decreased in patients with low back pain. Tests that canbe used for the assessment of abdominal muscles endurance; include supineisometric chest raise (SICR) and supine double straight-leg raise (SDSLR) tests.The aim of this study is to investigate the effects of visual feedback and verbalencouragement on endurance tests of deep abdominal muscles.Methods: In this two-factor mixed design study, a convenient sample of 40asymptomatic (healthy) participants (20 males and females each) aged between20-35 years was selected. Each subject performed the SICR and SDSLR tests under4 conditions: no feedback, visual feedback, verbal encouragement, and combinedvisual feedback and verbal encouragement. The tests were terminated when thesubject was no longer able to maintain a position. Furthermore, each test wasrepeated twice with 5 min interval and the average time was recorded for analysis.Results: Endurance test time was improved significantly when 2 types of feedbackwere given during the tests (P<0.01). However, combined visual feedback andverbal encouragement had superior effect on endurance test time compared tovisual feedback or verbal encouragement alone (P=0.01).Conclusion: The incorporation of verbal encouragement and visual feedback isan important factor in improving holding time during endurance tasks. Thismay have important implications on endurance training and rehabilitationprogrammes of abdominal muscles.

Temporary auditory deprivation is a serious complication of thisdisease and can result in auditory processing disorder, as demonstrated in paststudies. The objective of the current study was to investigate the effects of CMEduration on binaural processing and amblyaudia.Methods: Ninety-four children were examined, including 48 children (29girls=60%) with different CME durations (from 3 months to more than 9months) and 46 children (34 girls=73%) with no history of CME or a durationof less than 3 months CME. Persian versions of the dichotic digits and dichoticrhyme tests were applied.Results: Significant differences between the groups (P<0.001) in dichoticdigits difference (DDD) and dichotic rhyme difference (DRD) in free recallconditions were identified. With longer durations of CME, the DDD and DRDaverage scores were increased in the CME positive group, and the probability ofamblyaudia was also enhanced.Conclusion: A history of CME and the long-term auditory deprivation resultingfrom it in early childhood can increase the risk of amblyaudia.

Current research efforts are mainly focused on therapeutic procedures that potentially may modify disease progression. This preliminary study was designed as a single blind (examiner) randomized control trial to investigate the impact of conventional physical therapy on pain, and knee joint load in subjects with moderate knee osteoarthritis.Methods: Twelve participants diagnosed with moderate knee OA were randomly assigned into control and intervention groups. Three-dimensional knee kinematic and kinetic data were recorded during the gait before and after 10 sessions of conventional physical therapy. In addition, pain intensity was evaluated by visual analog scale and pain subscale of KOOS questionnaire. The control group did not receive any intervention during the same period. Gait parameters were analyzed within and between groups using nonparametric tests.Results: There was a significant difference between groups in baseline KOOS-pain Score and ML knee force (P =0.048 and P=0.01). Immediately after ten sessions of physical therapy the initial (first) peak of knee adduction moment was significantly (P=0.03) lower than that of the control group while the first and second peak of knee AP velocity were significantly (P=0.02, P =0.01 respectively) higher. In the intervention group, the second peaks of vertical and anteroposterior (AP) knee forces were strongly correlated with the pretest KOOS-pain Score (r =0.99 and r =0.98, P<0.001). Therefore a multivariate general linear model was adopted with adjustment to baseline KOOS-pain. By this adjustment, 51% alleviation of VAS pain score and 81% decrement of first peak of knee adduction moment in comparison to control group was statistically significant (P=0.02, P=0.03 respectively).Conclusion: It seems that ten sessions of conventional physical therapy may modify knee joint load in subjects with moderate knee osteoarthritis. Further research is recommended.

Assessment of this trait in stroke subjects with a standardized tool would promote the rehabilitation protocols and occupational therapy interventions. Therefore, the objective of this study was to standardize the Connor-Davidson Resilience Scale (CD-RISC) for Persian Iranian people who have had strokes.Methods: A descriptive observational study was adopted in order to standardize the CD-RISC in stroke population. The population was comprised of 34 female and 29 male subjects with a mean age of 51.4±10.6 years and the history of ischemic or hemorrhagic cerebrovascular accidents. Subjects were recruited based on inclusion criteria within the period of two months between May and July of 2014. Descriptive statistics were calculated along with the Cronbach's alpha to determine reliability. Standard multiple regression analyses searched for any correlation between variables and resilience.Results: Statistical parameters revealed a mean of 58.4±15.5 for CD-RISC raw scores. Percentile ranks were also calculated from raw data. Cronbach's alpha of 0.892 revealed that the CD-RISC had high reliability for the population of this study. Multiple regression analyses showed that the functional status was the only variable that uniquely predicted subjects’ resilience (ß = 0.41; P< 0.01). Conclusion: The findings of this research confirmed applicability of CD-RISC in Iranian people who have had strokes. The standardized CD-RISC was determined to be suitable for use in the clinic and for utilization in research studies in Iranian people status post-stroke.
