Examining the Relationship and the Gender Differences between Re-Injury Worry, Confidence, and Attention after a Sport Musculoskeletal Injury.

Introduction: A sport injury is an unfortunate event that can significantly impact the injured athletes' psychology. There have been no studies examining gender differences in the psychological state after a sport-related musculoskeletal injury. Τhe aims of the current study were to (a) investigate the relationship between re-injury worry levels, confidence, and attention in the injured athletes who followed a rehabilitation program in order to return to competition, and (b) compare differences in these psychological factors between male and female athletes. Methods: A cross-sectional research design was used. A total of 60 athletes (30 men and 30 women) volunteered to participate, aged 25.50 ± 5.25 years old, all of whom had experienced a musculoskeletal injury within the past year. Three validated questionnaires, i.e., the Causes of Re-Injury Worry Questionnaire, the Sport Confidence Questionnaire of Rehabilitated Athletes Returning to Competition, and the Attention Questionnaire of Rehabilitated Athletes Returning to Competition, were completed by the participants on their first competitive game after their rehabilitation program. Results: All of the athletes experienced average levels of re-injury worry due to their opponents' ability and distraction attention, and high levels of confidence and functional attention. Many factors from the questionnaires were correlated with each other. Men experienced lower levels of re-injury worry due to rehabilitation compared to the women athletes (U = 329.00, p < 0.05), and women exhibited higher "Re-injury Worry due to Opponent's Ability" compared to the men athletes (U = 292.00, p < 0.01). Conclusions: A strong relationship was found between re-injury worry, confidence, and attention, with few gender differences. Since there is no previous research examining re-injury worry, confidence, and attention between men and women, future research with larger and more homogeneous samples is needed to confirm the present results.

The Effectiveness of an Exercise Program on Muscle Strength and Range of Motion on Upper Limbs, Functional Ability and Depression at Early Stage of Dementia.

Background: Dementia involves the loss of cognitive abilities and represents a decline from the prior level of function, which impairs functional abilities in day-to-day life. The purpose of the present study is to examine the effectiveness of an exercise program on the muscle strength and range of motion of the upper limbs, the functional status, and the depression of elderly people with early stage dementia. Methods: The sample consisted of 60 elderly people with early stage dementia who were randomly divided into a control and an experimental group of 30 participants each. The experimental group received a 12-week Otago exercise program with 45 min duration of each session. The control group received usual care without doing exercise. The outcome measures of muscle strength and range of motion of the upper limbs, the functional status, and the depression were assessed by valid instruments and tests at the beginning and at the end of the intervention program. Repeated measures one-way ANOVA and Mann-Whitney tests examined the differences between the two groups at the end of the 12-week exercise program. Results: Statistically significant differences were found between the experimental and control groups in the entire outcome measures (functional ability F = 9.35 p < 0.05; muscle strength right hand F = 32.33, p < 0.05 left hand U = 95.50 p < 0.01; e.g., range of motion shoulder extension U = 104.00 p < 0.01), except depression. Conclusions: Both muscle strength and range of motion of the upper limbs, as well as the functional ability, were improved by the exercise program. Further research is needed to investigate the present results, in particular to explore the long-term cognitive, behavioral, and functional status outcomes of exercise in the early stages of dementia.

The Relationship between Heart Rate Variability, Pain Intensity, Pain Catastrophizing, Disability, Quality of Life and Range of Cervical Motion in Patients with Chronic Non-Specific Neck Pain: A Cross-Sectional Study.

The purpose of the present cross-sectional study was to examine the relationship between heart rate variability (HRV) and the range of cervical motion, disability, pain intensity, pain catastrophizing, and quality of life in patients with chronic, non-specific neck pain. Thirty-five patients, aged 20-48 years, with chronic non-specific neck pain, completed validated questionnaires regarding neck pain intensity, pain-associated disability, catastrophic thoughts, and quality of life. The range of cervical motion was assessed using a digital goniometer. HRV indices were recorded in three positions (supine, sitting, and standing) through a smartphone application. Several significant correlations were observed between HRV indices and neck pain disability, the helplessness factor of catastrophizing, neck rotation, and quality of life. These correlations were only observed in the standing position. Pain catastrophizing was positively correlated with disability and pain intensity during active neck movement (Pearson r = 0.544, p < 0.01; Pearson r = 0.605, p < 0.01, respectively). Quality of life was negatively correlated with pain intensity during active movement (Pearson r = -0.347, p < 0.05). HRV indices were correlated with the psychological and physical domains of neck pain. These cardiac indices have been related to neck pain variables in some previous studies. Further research is needed to confirm this relationship in different daily conditions.

The Effect of Physiotherapy on Dyspnea, Muscle Strength and Functional Status in Patients with Long COVID Syndrome.

BACKGROUND: Patients who were infected with COVID-19 may experience Long COVID syndrome. We examined the effectiveness of physiotherapy on dyspnea, muscle strength, and functional status in Long COVID syndrome. METHODS: The exercise group underwent an 8-week supervised physiotherapeutic program consisting of interval aerobic exercise and strengthening exercises, each lasting 30 min. The control group did not engage in any exercise. Dyspnea, muscle strength, and functional status were assessed at the beginning and end of the intervention in both groups. RESULTS: No significant baseline differences were found between the two groups. The exercise group demonstrated improvements compared to baseline in dyspnea, quadriceps muscle strength, and functional status. Specifically, there was a significant increase of 3.7 lifts in the 60-s sit-to-stand test (p = 0.01), an increase of 5.86 kg in right quadriceps muscle strength (p = 0.03), an increase of 8.26 kg in left quadriceps muscle strength (p = 0.01), and a decrease in dyspnea score by 0.95 points (p = 0.02). CONCLUSIONS: Similar studies have reported improvements in dyspnea, muscle strength, and functional status in the exercise group. However, further research with larger sample sizes is needed to confirm these findings.

Translation, Adaptation and Validation of the Greek Version of the Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow Score in Greek Overhead Athletes.

Athletes engaging in overhead activities often face injury risks, emphasising the need for reliable assessment tools. This study focused on the translation and psychometric evaluation of the Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow Score into Greek (Gr-KJOC) for assessing upper limb function in Greek-speaking overhead athletes. The Gr-KJOC underwent meticulous translation and adaptation processes, ensuring linguistic equivalence and cultural relevance. A sample of 60 athletes participated in the psychometric evaluation, including assessments of internal consistency, test-retest reliability, construct validity, and structural validity. The Gr-KJOC demonstrated excellent internal consistency (Cronbach's alpha = 0.95), indicating consistent measurement of the underlying construct. Test-retest reliability was excellent (ICC = 0.95), with low measurement errors. Construct validity was confirmed through correlations with the Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire. Structural validity revealed a unidimensional structure with high explained variance (75%). No floor or ceiling effects were observed, and the questionnaire proved feasible, with an average completion time of 6 min. The Gr-KJOC emerges as a reliable, valid, and feasible tool for evaluating upper limb function in Greek-speaking overhead athletes. Its psychometric properties support its utility in clinical and research contexts, contributing to the effective assessment and management of shoulder and elbow conditions in the realm of overhead sports in Greece.

The Effectiveness of External Verbal Feedback on Balance in Athletes with Chronic Ankle Instability.

Chronic ankle instability (CAI) is characterized by muscle weakness and impaired neuromuscular control. This study aimed (a) to assess the impact of external verbal feedback on the dynamic balance of athletes with CAI and (b) to examine the maintenance of dynamic balance ability after the end of the completion of the intervention balance program. Thirty athletes (mean age 21.63 ± 1.53) were randomly divided into three groups: an experimental group with external verbal feedback, 1st control group without external verbal feedback and the 2nd control group without balance training and without feedback. Assessments using a balance board and the 'Y-balance' test were conducted before and after the balance training period. Additionally, participants completed the Cumberland Ankle Joint Instability Tool. A retention test of balance ability was administered after the 4-week intervention period. Statistical analysis revealed a significant overall improvement in balance (F(2,36) =5.96, p = 0.006, partial η2 =0.249), including those with no balance training, but no significant differences between the groups. Thus, the external verbal feedback did not show a positive impact on the balance ability between the three different groups. Also, the experimental group with the external verbal feedback demonstrated maintenance of dynamic balance learning ability. Although it appears that balance training has a positive effect on the dynamic balance of individuals with CAI, a non-positive impact of external verbal feedback was found. Also, it appears that external verbal feedback significantly led to sustained retention of balance learning ability. Further research is recommended to validate these findings.

Preliminary Insights into the Diagnostic Accuracy of the Modified Arm Care Screen Test for Overhead Athletes: An On-Field Tool for Injury Prevention.

BACKGROUND: The Arm Care Screen was developed to detect musculoskeletal limitations that could affect performance or even increase the risk for shoulder injuries in overhead athletes. This study aimed to assess the discriminant validity of the modified Arm Care Screen in overhead athletes. METHODS: Sixty-two overhead athletes (mean age: 24.5 ± 4.2 years) were recruited. The athletes underwent a comprehensive Arm Care Screen evaluation, including reciprocal shoulder mobility, total body rotation, lower body diagonal reach, and rotary stability assessments. Ten different musculoskeletal measurements were independently measured by two physical therapists. RESULTS: The modified Arm Care Screen showed moderate to strong associations (phi values ranged from 0.273 to 0.905) with the respective musculoskeletal range of motion and balance measurements. Sensitivity ranged from 81.25% to 88.57%, indicating a high true positive rate, and specificity ranged from 43.75% to 94.44%, indicating a moderate to strong positive rate. Positive and negative likelihood ratios ranged from 1.48 to 15.92 and 0.12 to 0.38, respectively. The positive and negative predictive value ranged from 58.14% to 92% and from 73.68% to 93.18%, respectively. The accuracy of the modified ACS ranged from 62.90% to 91.94%. CONCLUSION: The modified Arm Care Screen demonstrated promising diagnostic accuracy in identifying significant movement restrictions.

The effectiveness of mental imagery on motor, cognitive and emotional status of older people with early-stage dementia: A study protocol.

Dementia involves the loss of cognitive abilities and represents a decline from the prior level of function which impairs functional abilities in day-to-day life. No previous experimental research has been done to assess mental imagery (MI) effectiveness in the motor, cognitive and emotional status of individuals with early-stage dementia. One hundred and forty older individuals with early-stage dementia from the Day Care Centre of the Alzheimer Association in Athens will take part in this study. The sample will be randomly divided into three groups: MI and physical exercise (intervention group), only physical exercise (1st control group), and neither MI nor physical exercise (2nd control group). Assessment will be obtained one week prior to the program, in the middle of the program (6th week of the intervention program) and after the end of the program (13th week of the intervention program). Participants of the intervention group will perform a 30-minute MI programme after the end of every physiotherapy session. Reliable and valid instruments will be used to assess the primary outcomes, i.e., balance and functional status as well as the secondary outcomes i.e., cognitive ability, emotional state and quality of life. The two-way Mixed ANOVA with factors 'intervention' (between groups) and 'time' (within group) will be used as a statistical analysis. Approvals of clinical trial protocol: a) UNIWA Research Committee study protocol approval: 93292 - 26/10/2021. b) ClinicalTrials.gov: ID NCT05232526.

Re-injury worry, confidence and attention as predictors of a sport re-injury during a competitive season.

Rehabilitation from sport injury involves not only physical, but also psychological considerations. Re-injury worry, confidence and attention are characteristics that may affect athletes' returning to competition after a sport injury. The study aimed to describe the predictive ability of the re-injury worry, confidence, and attention to the total of re-injuries at the new competitive season. The sample was 80 male athletes with at least three years of competitive experience who had a sport musculoskeletal injury in the last 8 months and had followed properly their physiotherapy program. They were ready for re-entry into competitive sport. They completed on returning to competition: (a) the Causes of the Re-Injury Worry Questionnaire, (b) the Sport Confidence Questionnaire of Rehabilitated Athletes Returning to Competition and (c) the Attention Questionnaire of Rehabilitated Athletes Returning to Competition. The three valid and reliable instruments predict the total of re-injuries at the beginning and at the middle of the competitive season. Future research should be conducted to examine the relationship between the physical and psychological characteristics in re-injury's prediction from different contact sports.

Cross-cultural adaptation of the Pain Catastrophizing Scale in Greek clinical population.

BACKGROUND: Catastrophizing is an important psychological construct in mediating the behavioral response toward pain. OBJECTIVE: The purpose of this study is to examine the psychometric properties of the Pain Catastrophizing Scale (PCS) in Greek clinical population. METHODS: The scale was administered in 376 patients with chronic cervical and lumbar pain. Test-retest reliability, internal consistency (Cronbach α ) and concurrent validity were assessed. Exploratory (EFA) and Confirmatory Factor Analysis (CFA) were used to test the factorial validity of the hypothesized three factor structure. RESULTS: The PCS factors suggested high levels of test-retest reliability, whereas Cronbachs' α values were acceptable. The EFA yielded a three-factor solution and indicated a marginal fit to the data. CFA procedures indicated a rather acceptable fit to the data. The concurrent validity of the instrument was confirmed. CONCLUSION: PCS seems to be a reliable and valid instrument in Greek patients with chronic cervical and lumbar pain.

The effectiveness of exercise program after lumbar discectomy surgery.

A lumbar herniation disc appears as a major cause of lumbar pain and sciatica. The purpose of the present systematic review is to examine the effectiveness of such exercise programs on pain, disability, quality of life, strength and the assessed time required to return to work/normal activities after undergoing lumbar discectomy surgery. PubMed, MEDLINE, and Google Scholar were used for the selection of randomized controlled trials (RCTs). The PEDro scale was chosen to assess the methodological quality of the included studies. Seven RCTS met the inclusion criteria. According to the evaluation of the PEDro scale, one was considered as « high quality¼, five as « moderate quality¼ and one as « low quality¼. The mean score of the studies was 5.14. The results showed that after such exercise there was an improvement in pain, disability, quality of life, muscle strength and in time required to return to work. The exercise programs have a positive impact on the reduction of pain, disability, time required to return to work/normal activities as well as an increase in quality of life and muscle strength in patients with lumbar discectomy surgery.

Motor imagery as a method of maintaining performance in pianists during forced non-practice: a single case study.

Background: Musicians suffer from upper limb playing-related musculoskeletal disorders that often oblige them to periodic inactivity. Objectives: To assess the effectiveness of motor imagery as a means of practice when the physical piano practice is restricted. Methods: A 17-year-old healthy pianist participated in a single subject case study with a multiple baseline design (ABC design). Performance ability was assessed during a period of the no practice, then a period of performing motor imagery and again during a period of another no practice. Assessments were performed subjectively by a professional piano teacher and objectively by the Synthesia software. Three visual analog scales were used to record stress, fatigue, and general psychological state. The participant's motor imagery ability was recorded by the use of the Movement Imagery Questionnaire. Results: There was a statistically significant reduction in performance after no practice. There was no change in performance during motor imagery intervention. The pianist's scores moderately correlated with the general psychological state. The Synthesia scoring presented high correlations with professional piano teacher scoring. Conclusions: Motor imagery seemed to have a positive effect in maintaining the musician's performance level. Synthesia shows promise as an outcome measure for assessing music performance, although further research is needed.

Cross cultural adaptation, reliability, and validity of the Greek version of the Cumberland Ankle Instability Tool.

Objectives: This study's objective was to translate and cross-culturally adapt the Cumberland Ankle Instability Tool (CAIT) into the Greek language and to evaluate its psychometric properties.Methods: CAIT was translated and adapted into Greek according to official cross-cultural adaptation guidelines of self-reported measures. The Greek version of the CAIT (CAIT-GR) was tested for reliability (internal consistency, test-retest reliability), validity (discriminative and convergent validity) and floor-ceiling effects. Additionally, a cut-off value discriminating between stable and unstable ankles across healthy participants and participants with ankle complaints was calculated. A convenience sample of 123 Greek individuals was recruited, 43 of which had a history of at least one ankle sprain. All participants completed the final version of the CAIT-GR twice within 7-10 days. Participants with a history of ankle sprain also completed the Greek version of the Lower Extremity Functional Scale (LEFS) and the Visual Analogue Scale (VAS).Results: CAIT-GR mean scores were 26.9 ± 3.16 for participants without a history of ankle sprain and 20.6 ± 4.62 for the instability group. The cut-off value was at 24.5 points of the total CAIT score (range 0-30). CAIT-GR had a moderate correlation with VAS (0.54) and a high correlation with LEFS (0.735). Results indicated good discriminative validity, high internal consistency (Cronbach's alpha of 0.97) and excellent test-retest reliability (ICC2,1 = 0.97, 95%CI = 0.97-0.98). Neither a floor nor a ceiling effect was observed.Conclusions: The CAIT-GR questionnaire was found to be a reliable and valid measure for chronic ankle instability. It is therefore, available for use in future clinical research and practice.

The combination of inspiratory muscle training and high-flow nasal cannula oxygen therapy for promoting weaning outcomes in difficult-to-wean patients: protocol for a randomised controlled trial.

BACKGROUND: According to the literature, 20-30% of intubated patients are difficult to wean off mechanical ventilation and have a prolonged intensive care unit (ICU) stay with detrimental effects on muscle strength, functional ability and quality of life. Inspiratory muscle training (IMT) via a threshold device has been proposed as an effective exercise for minimising the effects of mechanical ventilation on respiratory muscles of critically ill patients with prolonged weaning. In addition, high-flow nasal cannula (HFNC) oxygen has been proved to provide efficient support for both high- and low-risk patients after extubation, thus preventing re-intubation. MATERIAL AND METHODS: A randomised controlled trial was designed to assess the efficacy of combining IMT and HFNC as therapeutic strategies for patients with high risk for weaning failure. Once patients with prognostic factors of difficult weaning are awake, ventilated with support settings and cooperative, they will be randomised to one of the two following study groups: intervention group (IMT and HFNC) and control group (IMT and Venturi mask). IMT will start as soon as possible. Each allocated oxygen delivery device will be applied immediately after extubation. IMT intervention will continue until patients' discharge from ICU. The primary outcome is the rate of weaning failure. Secondary outcomes are maximal inspiratory and expiratory strength, endurance of respiratory muscles, global muscle strength, functional ability and quality of life along with duration of ventilation (days) and ICU and hospital length of stay. CONCLUSION: The present study could significantly contribute to knowledge of how best to treat patients with difficult weaning and high risk of re-intubation.

Examining re-injury worry, confidence and attention after a sport musculoskeletal injury.

BACKGROUND: Sport injury is an unfortunate event which can have a major impact on the injured athletes' psychology. Athletes may experience re-injury worry and low levels of attention and confidence getting back to competition following a sport injury. The aim of the study was to examine re-injury worry, confidence and attention of previously injured athletes, before they returned to competition. METHODS: Cross-sectional research design. A total of 52 athletes volunteered for this study, aged 23.1±4.8 years old with a previous musculoskeletal injury during the last year. Participants completed the Causes of Re-Injury Worry Questionnaire, the Sport Confidence Questionnaire of Rehabilitated Athletes Returning to Competition and the Attention Questionnaire of Rehabilitated Athletes Returning to Competition, on their first competitive game after rehabilitation program. RESULTS: The athletes experienced average levels of re-injury worry and distraction attention and high levels of confidence and functional attention. The duration of injury, the medical and physiotherapy treatment and the absence from sport were significantly correlated with the questionnaire factors "Re-injury worry due to opponent's ability", "Functional attention" and "Distraction attention". CONCLUSIONS: Psychological characteristics of previously injured athletes may be influenced from the duration of: 1) medical treatment; 2) injury; 3) physiotherapy treatment; and 4) absence from sport, when they return to competition. More research needs to be conducted to confirm the present results.

Effect of neuromuscular stimulation and individualized rehabilitation on muscle strength in Intensive Care Unit survivors: A randomized trial.

PURPOSE: Intensive Care Unit (ICU) survivors experience muscle weakness leading to restrictions in functional ability. Neuromuscular electrical stimulation (NMES) has been an alternative to exercise in critically ill patients. The aim of our study was to investigate its effects along with individualized rehabilitation on muscle strength of ICU survivors. MATERIAL AND METHODS: Following ICU discharge, 128 patients (age: 53±16years) were randomly assigned to daily NMES sessions and individualized rehabilitation (NMES group) or to control group. Muscle strength was assessed by the Medical Research Council (MRC) score and hand grip at hospital discharge. Secondary outcomes were functional ability and hospital length of stay. RESULTS: MRC, handgrip, functional status and hospital length of stay did not differ at hospital discharge between groups (p>0.05). ΔMRC% one and two weeks after ICU discharge tended to be higher in NMES group, while it was significant higher in NMES group of patients with ICU-acquired weakness at two weeks (p=0.05). CONCLUSIONS: NMES and personalized physiotherapy in ICU survivors did not result in greater improvement of muscle strength and functional status at hospital discharge. However, in patients with ICU-aw NMES may be effective. The potential benefits of rehabilitation strategies should be explored in larger number of patients in future studies. CLINICAL TRIAL REGISTRATION: www.Clinicaltrials.gov: NCT01717833.

Comparing the psychometric properties of the pediatric outcomes data collection instrument and the activities scales for kids: a review.

The aim of this study was to review and evaluate the psychometric properties of two general musculoskeletal outcome measures focusing on pediatric physical disability, namely, the Pediatric Outcomes Data Collection Instrument (PODCI) and the Activities Scales for Kids (ASK). Although this review reveals the psychometric superiority of ASK to PODCI, further research should confirm the psychometric properties of both the instruments. A number of psychometric issues need to be further addressed. Specifically, future studies should examine additional types of reliability and validity, for example, content, construct, criterion, and discriminant with more sophisticated statistical analyses, for example, Aiken's item content validity coefficient and confirmatory factor analysis. Until these issues are addressed, researchers should be cautious utilizing these instruments in children with musculoskeletal problems in a clinical setting.

Development and validation of the attention questionnaire of rehabilitated athletes returning to competition.

The present study describes the development and validation of an instrument designed to examine athletes' selective attention returning to competition following a musculoskeletal injury--the attention questionnaire of rehabilitated athletes returning to competition (AQ-RARC). Using a sample of 186 rehabilitated athletes, exploratory factor analysis revealed a 10-item model that examines functional attention and distraction attention. Confirmatory factor analysis further supported the factorial validity of the AQ-RARC with another sample of 184 rehabilitated athletes. The two subscales have good internal consistency and test-retest reliability. The concurrent and discriminant validity of the new instrument were confirmed by examining correlations between the AQ-RARC with other constructs. It is concluded that the AQ-RARC is a valid and reliable instrument that can be used for clinical and research purposes.

Validity and reliability of the Greek version of the Quebec Back Pain Disability Scale.

OBJECTIVES: Low back pain is related to functional status and possible resulting disability. The Quebec Back Pain Disability Scale (QBPDS) has been used widely to evaluate functional disability in patients with low back pain. The purpose of this study was to assess: (a) the face and content validity, (b) the factor structure, (c) the concurrent validity, (d) the discriminant validity, (e) the internal consistency and the test-retest reliability (ICC) of the Greek version of the QBPDS. METHODS: One hundred and sixty patients with low back pain participated in the study. Face and content validity of the translated QBPDS were first investigated and afterwards exploratory factor analysis (EFA) was chosen to examine the factor structure of it. The concurrent and discriminant validity of the QBPDS was also assessed by a number of valid constructs. Finally, Cronbach α and Pearson r (ICC) were used to investigate the reliability of the instrument. RESULTS: The face and content validity of the QBPDS were supported and the EFA confirmed the sixth initial factor structure of the instrument. The concurrent and discriminant validity of it was confirmed by examining correlations between the QBPDS with other constructs. The Cronbach a and the ICCs indices of the instrument were acceptable. CONCLUSION: The Greek translation of the QBPDS provided reliable and valid instrument for the evaluation of Greek patients with low back pain.

Development and validation of the Causes of Re-Injury Worry Questionnaire.

Re-injury worry is an important construct in competitive sport that may influence performance and increase the risk of re-injury. However, there are currently no available instruments to measure the causes of re-injury worry. The purpose of this study was to develop the Causes of Re-Injury Worry Questionnaire (CR-IWQ). The study was conducted in three independent research phases to investigate the following: (a) the content relevance, (b) the factor structure and the factorial validity, (c) the concurrent validity, (d) the discriminant validity, and (e) the test-retest reliability (intraclass correlation coefficients; ICC), and the internal consistency of the instrument. Exploratory factor analysis (EFA) was chosen to examine the factor structure of the CR-IWQ. Confirmatory factor analysis (CFA) was used to examine further the factorial validity of the instrument. A number of valid constructs were used to assess the concurrent and discriminant validity of the CR-IWQ. The reliability of the new instrument was examined using Pearson r (ICC) and Cronbach α. Three hundred and seventy athletes with an acute musculoskeletal sport injury in the last year participated in the study. EFA revealed a 12-item model, representing two factors ("Re-injury worry due to rehabilitation" and "Re-injury worry due to opponent's ability"). CFA supported the two-factor model of the CR-IWQ. The concurrent and discriminant validity of the CR-IWQ was confirmed by examining correlations between the CR-IWQ with other constructs. The ICCs and the Cronbach α indices of the CR-IWQ were acceptable. We have demonstrated that the CR-IWQ is a good psychometric instrument that can be used for clinical and research purposes.
