The Turkish minimum dataset for chronic low back pain research: a cross-cultural adaptation of the National Institutes of Health Task Force Research Standards.

BACKGROUND: The US National Institutes of Health (NIH) has produced a minimal data set to promote more accurate and consistent reporting of clinical trials, facilitating easier comparison of research on low back pain patients worldwide. The NIH-minimal dataset has not been previously translated into Turkish, and its features are currently unknown. This study aimed to adapt the NIH-Minimal Data Set into Turkish and investigate its validity and reliability in Turkish-speaking patients with chronic low back pain (CLBP). METHODS: In the study, 245 patients with CLBP were included. Test-retest and internal consistency analyzes were performed to evaluate the reliability of the NIH-minimal dataset. The intraclass correlation coefficient (ICC2,1) value was used to assess test-retest analysis. Cronbach's alpha value was calculated for internal consistency. Total impact scores of the NIH-minimal dataset were compared with total scores of the Roland Morris Disability Questionnaire (RMDQ) and Oswestry Disability Index (ODI) to assess construct validity. The minimal detectable change (MDC95) was calculated based on the standard error of measurement (SEM95). RESULTS: The NIH-Minimal Data Set was found to have high test-retest reliability (ICC2,1 = 0.928) and high internal consistency (Cronbach α = 0.905). The NIH-minimal dataset correlated well with RMDQ and ODI (r = 0.750 and 0.810, respectively). There were no floor or ceiling effects. Also, SEM95 and MDC95 for the total score were 4.57 and 12.55, respectively. CONCLUSION: Considering all these data, it was concluded that the Turkish version of the NIH-minimal dataset is a valid and reliable outcome measure for evaluating patients with CLBP.

Effect of high voltage electrical stimulation in temporomandibular disorders: a randomized controlled trial.

OBJECTIVE: To examine the effects of high voltage electrical stimulation (HVES) on pain intensity, maximum mouth opening (MMO), cervical mobility, head position, pressure pain thresholds (PPTs), bite force, joint sounds, and jaw muscle strength in individuals with temporomandibular disorders (TMDs). METHODS: Thirty-four individuals with TMDs were randomly divided into the exercise group (EG) (n = 17) and the HVES group (HG) (n = 17). For 4 weeks, EG received exercise therapy alone, while HG received HVES (12 sessions in total, 3 days a week to anterior temporalis and masseter) in conjunction with exercise. RESULTS: After the treatment, in both groups, pain intensity significantly decreased (p < .001); MMO (7.27 mm in HG and 3.61 mm in EG), cervical mobility, head position, PPTs, bite force, and jaw muscle strength significantly increased (p = .043 to < .001). Joint sounds significantly decreased in the HG (p = .008). Left bite force (p = .040) and left medial pterygoid PPT (p = .013) increased more in EG. The change in left bite force in EG over time was significant (p = .040; ηp2 = .126). The effect sizes of treatments were medium to large (from .527 to 1.602) for the evaluated parameters. CONCLUSION: Although exercise alone was effective in many parameters evaluated, additional application of HVES provided further improvement for pain, MMO, cervical mobility, PPTs, jaw muscle strength and joint sounds. HVES can be routinely used in clinics for individuals with TMDs.

Effectiveness of osteopathic manipulative applications on hypothalamic-pituitary-adrenal (HPA) axis in youth with major depressive disorder: a randomized double-blind, placebo-controlled trial.

CONTEXT: Osteopathic treatments regulate the neurovegetative system through joint mobilizations and manipulations, and myofascial and craniosacral techniques. Despite the growing body of research, the precise impact of osteopathic medicine on the autonomic nervous system (ANS) is not yet fully elucidated. As to Kuchera's techniques, the stimulation of the sympathetic trunk and prevertebral ganglia contributed to harmonization of the sympathetic activity. However, potential relationships between the harmonization of the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis largely remain uncertain and warrant further exploration. OBJECTIVES: This study was designed to evaluate the effectiveness of the osteopathic sympathetic harmonization (OSH) on the SNS and the HPA axis in youth with major depressive disorder (MDD). METHODS: The study included 39 youths aged 15-21 years and diagnosed with MDD. The participants were randomly assigned into either the OSH or the placebo group. Stimulation was performed on the sympathetic truncus and prevertebral ganglia in the OSH group. The stimulation of the placebo group was performed with a lighter touch and a shorter duration in similar areas. Each participant completed the Beck Depression Inventory (BDI) and the State and Trait Anxiety Inventory (SAI and TAI) before the application. Blood pressure (BP) and pulse measurements were made, and saliva samples were taken before, immediately after, and 20 min after application. RESULTS: The baseline BDI (p=0.617) and TAI (p=0.322) scores were similar in both groups. Although the SAI scores decreased in both groups postintervention, no statistically significant difference was found between the two groups. Subjects who received OSH had a decrease in α-amylase level (p=0.028) and an increase in cortisol level (p=0.009) 20 min after the procedure. CONCLUSIONS: Following OSH application in depressed youth, SNS activity may decrease, whereas HPA axis activity may increase. Future studies may examine the therapeutic efficacy of repeated OSH applications in depressed individuals.

Psychometric properties of the Fonseca Anamnestic Index (FAI) for temporomandibular disorders: Turkish version, responsiveness, reliability, and validity study.

PURPOSE: Many assessment tools have been proposed for use in clinical practice and research on individuals with temporomandibular disorders (TMD). It aimed to translate the Fonseca Anamnestic Index into Turkish (FAI/T) and examine the responsiveness, reliability and validity of the FAI/T in this study. MATERIALS AND METHODS: Two hundred forty-nine individuals (207 female/42 male) with TMD were included in this study according to the RDC/TMD (muscle disorders, disc displacement, arthralgia and mixed disorders (muscle disorders and disc displacement)). Reliability was evaluated with test-retest reliability, internal consistency, and reproducibility. Validity was assessed with structural validity, construct validity, content validity, and face validity. In addition, responsiveness and floor and ceiling effects were also examined. RESULTS: The ICC value (0.906) and Cronbach's α (0.951) of the (FAI/T) were excellent. Following Explarotary Factor Analysis, two factors were extracted, accounting for 51.859% of the total variation. Structural validity, construct validity, content validity, and face validity analyses proved the validity of the FAI/T. The responsiveness analysis showed that the Turkish FAI and its subscales were able to detect change over time. CONCLUSIONS: The FAI/T has shown excellent reliability and good validity. The FAI/T can assess the symptoms of Turkish-speaking persons with TMD.Clinical Trials registration number: NCT04274985.

Turkish version of Fonseca Anamnestic Index has been translated into Turkish from English version.Turkish version of Fonseca Anamnestic Index has excellent reliability and good validity.The Turkish version of the Fonseca Anamnestic Index and its subscales are able to detect change over time.Turkish clinicians and researchers could easily use the Turkish version of the Fonseca Anamnestic Index to assess the Turkish population with temporomandibular disorders.

Comparison of balance and function in the long term after all arthroscopic ATFL repair surgery.

INTRODUCTION: We compared the balance, ROM, clinical scores, kinesiophobia and functional outcomes of patients after all-arthroscopic ATFL repair surgery with the non-operated side and healthy control group. MATERIALS AND METHODS: Twenty-five patients with follow up time 37.32 ± 12.51 months and twenty-five healthy controls participated in the study. Postural stability was evaluated with the Biodex® balance system by measuring overall (OSI), anterior-posterior (API), and mediolateral (MLI) stability index. Dynamic balance and function were measured using the Y-balance test (YBT) and single-leg hop test (SLH). Limb symmetry index for SLH and contralateral comparisons (YBT, OSI, API, MLI) was performed. The AOFAS score and the Tampa Scale of Kinesiophobia (TSK) were applied. Two subgroups were created (with OLT and without OLT). RESULTS: There was no statistically significant difference between subgroups. There was no statistically significant difference between bilateral OSI, API, MLI values and YBT anterior reach distances of all groups. Single leg OSI (0.78 ± 0.27/0.55 ± 0.12), API (0.55 ± 0.22/0.41 ± 0.10), and MLI (0.40 ± 0.16/ 0.26 ± 0.08) values were significantly worse and YBT posteromedial (73.88 ± 15.70/89.62 ± 12.25), posterolateral reach (78.03 ± 14.08/92.62 ± 8.25) and the SLH distance (117.14 ± 27.84/165.90 ± 20.91) were significantly lower on the patients than controls (p < 0.05), respectively. In contralateral comparisons, all reach distances on YBT were similar and SLH limb symmetry index of the operated side was 98.25%. AOFAS scores of the patients were 92.62 ± 11.13, TSK scores were 46.45 ± 11.32, and 21 patients (84%) had kinesiophobia. CONCLUSION: AOFAS score, limb symmetry index, and bilateral balance of the patients were successful; however, there is single-leg postural stability insufficiency and kinesiophobia. Although the extremity symmetry index of the operated side of the patients was 98.25, the fact that these values are lower than those of the healthy control may have been caused by kinesiophobia. During the long-term rehabilitation, kinesiophobia should be considered and single-leg balance exercises should be monitored during the rehabilitation period. LEVEL OF EVIDENCE: Level III.

The effect of orthotics on plantar pressure in children with infantile tibia vara (Blount's disease).

Albeit some studies have revealed the effectiveness of the orthosis use in infantile tibia vara (ITV), hitherto no study has shown the effects of these orthosis on plantar pressures. This study aims to reveals the effects of orthosis on plantar pressure in infantile tibia vara. Fourteen children (mean age: 27.14 ± 5.00 months) with infantile tibia vara made up the study group and 14 healthy children (mean age: 26.42 ± 5.33 months) constituted the control group. The plantar pressure distribution was evaluated with WALKINSENSE. ITV group was evaluated before and after orthosis. The control group did not use orthosis and was evaluated once. After orthosis, it was determined that lateral foot pressure decreased, and medial foot pressure increased in the hindfoot. After orthosis, medial pressure decreased in the forefoot (p < 0.05). The pressure in the forefoot of the control group was significantly higher than that in the ITV group (before and after orthosis) (p < 0.05). After orthosis, the pressure was similar in the posterior and mid-foot sensors between the ITV group and the control group (p˃0.05). The orthosis can be effective in achieving the normalization of the soles pressure distribution in children with ITV.

Cross-cultural adaptation, reliability, and validity of the Turkish version of the Craniofacial Pain and Disability Inventory (CF-PDI/T) for individuals with temporomandibular disorders.

PURPOSE: To translate the Craniofacial Pain and Disability Inventory into Turkish (CF-PDI/T) and to examine its reliability and validity. MATERIALS AND METHODS: Cultural adaptation of CF-PDI/T was conducted according to international standards. The psychometric analyses included reliability by internal consistency (Cronbach's alpha) and test/retest reliability (intraclass correlation coefficient, ICC); structural validity was evaluated with exploratory factor analysis (EFA), confirmatory factor analysis (CFA); and construct validity was investigated by matching (a priori hypotheses) the CF-PDI/T with the Numeric Rating Scale (NRS), Headache Impact Test-6 (HIT-6), Tampa Scale for Kinesiophobia for Temporomandibular Disorders-12 (TSK-TMD-12), Pain Catastrophizing Scale (PCS), Neck Disability Index (NDI), Fonseca Anamnestic Index (FAI), and Jaw Functional Limitation Scale-20 (JFLS-20). Correlations ranging from low to high were expected. RESULTS: CF-PDI/T showed excellent test-retest reliability (ICC = 0.971), excellent internal consistency (Cronbach's α = 0.985), and low to high correlation with NRS, HIT-6, TSK-TMD, PCS, NDI, FAI, and JFLS-20. Following EFA, three factors ("pain and psychosocial limitation", "jaw functional status", and "frequency comorbidities and disability") were extracted, accounting for 55.028% of the total variation. CONCLUSIONS: The CF-PDI/T is a reliable and valid instrument to assess the symptoms and disability in the Turkish population with temporomandibular disorders. Clinical trial registration number: NCT03837587.Implications for rehabilitationThe Spanish version of the Craniofacial Pain and Disability Inventory is a highly reliable and good valid outcome measure to evaluate disability and treatment outcomes for individuals with temporomandibular disorders (TMDs).We suggest the Turkish version of the Craniofacial Pain and Disability Inventory (CF-PDI/T) be used in the Turkish population to indicate small changes in the severity of disorder of individuals with TMDs until a normal quality of life is achieved.The CF-PDI/T can be used with high reliability and validity by experienced and inexperienced dentists and physiotherapists.

Does Venipuncture Increase Lymphedema by Triggering Inflammation or Infection? An Experimental Rabbit Ear Lymphedema Model Study.

Background: Recent guidelines recommend avoiding venipuncture to prevent lymphedema for breast cancer patients. This study investigated whether single or multiple sterile venipuncture procedures develop a systemic inflammation or infection and increase lymphedema in the rabbit ear lymphedema model. Methods and Results: Eighteen New Zealand white female rabbits were included. The right ear lymphedema model was created by surgical procedure; then, rabbits were divided into three randomized groups. Single and multiple venipuncture procedures were applied at least the 60th day after surgery for Group I and II, respectively. Group III was a control group. C-reactive protein (CRP) and procalcitonin (PCT) levels were analyzed to determine inflammation and infection. Ear thickness measurements were applied using a vernier caliper to assess the differences in lymphedema between the ears. All rabbits were euthanized on the 90th day after surgery. Histopathological analysis was performed to evaluate lymphedema by measuring tissue thicknesses. Ear thickness measurements showed that ear lymphedema was developed and maintained with surgical operation in all groups (p < 0.05). There was no difference in the ear thickness measurements between and within-groups results (p > 0.05). CRP and PCT levels were below the lower detection levels in all groups. According to the differences of histopathological ear distances, there were significant differences within-groups for all groups (p < 0.05), and no differences were identified between groups (p > 0.05). Conclusion: This experimental study demonstrated that single or multiple sterile venipuncture procedures did not trigger infection or inflammation and did not exacerbate ear lymphedema in the rabbit ear lymphedema model.

Comparison of the effectiveness of instrument-assisted soft tissue mobilization and extracorporeal shock wave therapy in myofascial pain syndrome.

Background/aim: To compare the effectiveness of instrument-assisted soft tissue mobilization (IASTM) and extracorporeal shock wave therapy (ESWT) used in myofascial pain syndrome (MPS) and to determine whether they are superior to conservative treatment (CT). Materials and methods: A total of 42 female patients (aged 18-60 years) diagnosed with MPS were enrolled and randomly assigned to either the CT (n = 14), CT+IASTM (n = 14), or CT+ESWT group (n = 14). All of the groups received treatment for 3 weeks (CT: 5 sessions per week, 15 sessions in total, ESWT and IASTM: 2 sessions per week, 6 sessions in total). Neck stretching exercises were given to all of the patients as a home program. The pain intensity of the patients was determined using the visual analog scale (VAS). The pressure pain threshold (PPT) was measured with an algometer. Cervical joint range of motion (ROM) was measured with a cervical ROM (CROM) device. Pain, cervical disability, quality of life, and sleep disturbances were evaluated with the Neck Outcome Score (NOOS). Depression and anxiety parameters were evaluated with the Hospital Anxiety and Depression Scale (HADS). Evaluations were made before treatment and 3 days after the last treatment session. Results: The CT+IASTM group was more successful than the other groups in terms of pain intensity, PPT, and improvements in the ROM parameters (p < 0.05). No significant difference was found between the NOOS and HADS scores of the groups when the posttreatment changes were compared to pretreatment (p > 0.05). Conclusions: All 3 of these treatments can be used to alleviate the negative effects of MPS. IASTM treatment can be preferred primarily in the creation of combined treatment programs for patients with ROM limitations and low PPTs.

The original VISA-G questionnaire was translated into Turkish language using Beaton guidelines. The Turkish version of the VISA-G, Harris Hip Score (HHS), Oswestry Disability Index (ODI), Oxford Hip Score (OHS), and International Physical Activity Questionnaire (IPAQ) were applied to 108 individuals with GTPS for convergent validity. The VISA-G was retested to investigate its reliability after one week. RESULTS: The VISA-G had a good correlation with HHS (r = 0.694, p < .001), ODI (r = -0.659, p < .001), OHS (r = 0.678, p < .001), and IPAQ (r = 0.440, p < .001). The reliability and internal consistency were excellent (ICC (2,1) value = 0.943; Cronbach's α = 0.946, respectively). And no floor and ceiling effects were revealed related VISA-G. CONCLUSION: The Turkish version of the VISA-G has good validity and excellent reliability. It can be used in clinical and research practices in the Turkish population with GTPS.

Reliability and validation of Turkish version of the Dallas Pain Questionnaire.

OBJECTIVES: Evaluation of low back pain (LBP) requires a condition specific disability questionnaire along with pain and satisfaction measure such as self-assessment pain scales. Dallas Pain Questionnaire (DPQ) is a 16-item visual analog scale, developed for evaluating patient's cognitions about the percentage that chronic pain affects four aspects of the subject's lives. It's easy to understand; can be answered in 3-5 min and can be scored in <1 min. This reliability and validation study offers health-care providers an opportunity to utilize this distinct questionnaire in Turkish population with back pain. The objectives are translation of Dallas questionnaire from English to Turkish language and to perform validation and reliability study. METHODS: A total of 102 patients (79 women and 23 men) with mean age of 50.2 years and LBP for at least 3 months answered DPQ along with five other previously translated and validated questionnaires in Turkish language. Fifty-nine of these patients participated retest reliability after 7 days. Internal consistency and test-retest analyzes were conducted to determine the reliability and convergent validity was evaluated for the validation study. RESULTS: The questionnaire was noted to have high internal consistency. The test-retest analysis revealed an excellent correlation (ICC=0.969). Pearson correlation coefficient shows that all subscales (sections) of DPQ are significant and comparable with each of the other questionnaires included in this study proving that it has sufficient convergent validity (p<0.001). CONCLUSION: The Turkish version of DPQ is content, valid, and reliable. DPQ is sensitive to use in patients with LBP.

Development, reliability and validity of the Closed Kinetic Chain Lower Extremity Stability Test (CKCLEST): a new clinical performance test.

This study aimed to develop and determine the test-retest, intra- and interrater reliability, and validity of the Closed Kinetic Chain Lower Extremity Stability Test (CKCLEST). Three-blinded, cross-sectional, repeated-measures clinical measurement reliability trial. Fifty young adults participated in this study. To assess the reliability of CKCLEST, intraclass correlation coefficient, standard error of measurement, minimal detectable change, and Bland-Altman plot were used. For concurrent validity of CKCLEST was applied Spearman correlation analysis with Vertical Jump Test, Isokinetic Dynamometer Test, Single-Leg Hop Test, and Prone Bridge Test. All analyses were made for both the best score and the average score. CKCLEST showed excellent reliability. ICC for test-retest reliability (0.93; 0.84), intrarater reliability (rater 1: 0.90; 0.83- rater 2: 0.93; 0.85), and interrater reliability (0.90; 0.83) was calculated for average score and best score, respectively. CKCLEST was found to be moderately correlated with each of the tests. CKCLEST is a highly reliable, valid, and new clinical assessment tool.

The Coping Strategies Questionnaire: Translation, cultural adaptation, reliability and validity in Turkish-speaking patients with chronic musculoskeletal pain.

BACKGROUND: The use of pain coping questionnaires is advantageous when selecting cognitive and behavioral targets for chronic pain management. The objective of this study was to investigate adaptation, validity, and reliability of the Coping Strategies Questionnaire (CSQ) in Turkish population with chronic musculoskeletal pain. METHODS: The Turkish version of the questionnaire (CSQ-T) was checked in terms of reliability and validity with a convenience sample of 123 patients with chronic musculoskeletal pain. Reliability (test-retest) analyses were conducted by means of a retest 48 hours later with a sub-group of 40 patients. Construct validity of the CSQ was checked through convergent validity with the Hospital Anxiety and Depression Scale (HADS) and the Short Form-36 (SF-36) health survey. RESULTS: Cronbach's alpha of the subscales ranged from 0.814 to 0.934 and the test-retest reliability ranged from 0.800 to 0.944. Neither floor nor ceiling effects (15%) were found in the subscales (13.8%) and the total score (4.1%) of the CSQ-T. Factor analysis indicated that the scale had two factors. The total CSQ-T score was correlated with both the HADS (r: -0.636/-0.549) and the SF-36 (r: 0.701/0.768). CONCLUSION: The CSQ-T is a reliable and valid measure for assessing patients with chronic musculoskeletal pain.

OBJECTIVE: This study aimed to validate the Turkish version of the Low Back Outcome Score and check its reliability in patients with chronic low back pain (LBP). METHODS: Overall, 105 patients (81 women and 24 men; mean age: 49.5 years (18-65 years)) with a complaint of LBP for at least 3 months were included in this study. Test-retest reliability was assessed after 7 days. Overall score of LBOS was compared with the overall scores of "Rolland-Morris Disability Questionnaire," "Oswestry Disability Index," "Quebec Back Pain Disability Scale," "SF-36," and "Bournemouth Questionnaire for Back Pain" to calculate the convergent validity by using Pearson correlation coefficient. RESULTS: The questionnaire was noted to have high internal consistency. The test-retest analysis revealed an excellent correlation (ICC=0.80). Pearson correlation coefficient of the LBOS was assessed using VAS and had an excellent correlation with all the questionnaires included in this study. CONCLUSION: The Turkish version of the LBOS questionnaire appeared to be a valid and reliable outcome measure. LEVEL OF EVIDENCE: Level III, Diagnostic study.

Reliability and validity of the Turkish version of the Core Outcome Measures Index for the neck pain.

PURPOSE: The Core Outcome Measures Index (COMI) is a short and multidimensional scale covering all domains recommended to be included in outcome measures for patients with neck pain. The purpose of the present study was to translate and cross culturally adapt the COMI into Turkish and to test its reliability and validity in patients with neck pain. METHODS: One hundred and six patients with a complaint of chronic neck pain (> 3 months) were enrolled in the present study. Participants completed a questionnaire booklet containing the COMI-neck, Neck Disability Index (NDI), Neck Pain and Disability Scale (NPDS), Short Form-36 (SF-36), and pain Numeric Rating Scale (NRS). The validation of the COMI included the assessment of its construct validity and reliability. RESULTS: Cronbach's alpha value of the questionnaire was found to be 0.774 indicating a high internal consistency. Intraclass correlation coefficient values for test-retest reliability were found to be in the range of 0.817-0.986, which indicates a sufficient level of test-retest reliability. Pearson's correlation coefficient values of the COMI with SF-36, NDI, NPDS, and NRS ranged between 0.417 and 0.700, indicating a good correlation. CONCLUSION: Considering the analyses, it was concluded that the Turkish version of the COMI is a valid and reliable scale for chronic neck pain patients. These slides can be retrieved under Electronic Supplementary Material.

Cross-cultural adaptation, reliability, and validity of the Turkish version of the Neck OutcOme Score

Background/aim: This study aims to determine the validity and reliability of the Turkish version of the Neck OutcOme Score (NOOS). Materials and methods: Two hundred eight patients suffering from nonspecific neck pain participated in the study. Test­retest reliability and internal consistency were assessed using intraclass correlation coefficients (2, 1) and Cronbach's alpha, respectively. The dimensionality was investigated with the factor analysis. The construct validity was determined by testing whether the hypothesis of correlations between NOOS subscales, Short Form-36 subscales, and the Neck Disability Index were met using Spearman's rank correlation coefficient. Ceiling/floor effects and measurement error were tested as well. Results: The intraclass correlation coefficient results varied between 0.721 and 0.844. Cronbach's alpha values of the subscale were found to be between 0.847 and 0.916 in the internal consistency analysis. The factor analysis showed that the questionnaire has five factors. Floor/ceiling effects were considered not to be present. Conclusion: It was found that the Turkish version of the NOOS is valid and reliable.

Cross-cultural adaptation, validity, and reliability of the Turkish version of the Patient-Rated Elbow Evaluation.

INTRODUCTION: The Patient-Rated Elbow Evaluation (PREE) is a joint-specific, self-administered outcome measure used to determine the level of pain and disability in patients with various elbow pathologies. The aim of this study was to cross-culturally adapt the PREE into Turkish (PREE-T) and to test its reliability and validity. METHODS: Fifty-nine patients with elbow disorders were included in the present study. The original version of the PREE was translated and culturally adapted into Turkish by following standard procedure. Test-retest reliability and internal consistency were determined using intraclass correlation coefficient and Cronbach's alpha, respectively. Construct validity of PREE-T was determined with Disabilities of the Arm, Shoulder, and Hand (DASH) and Short Form-36 (SF-36) questionnaires by using Pearson's correlation coefficient analysis. Floor and ceiling effects were also analyzed. RESULTS: A high internal consistency (Cronbach's alpha of 0.959) and an excellent test-retest reliability (the intraclass correlation coefficient of 0.970) indicated that the PREE-T was reliable. Neither floor nor ceiling effects were observed in sub-parameters (0-1.7%) and the total score (0%) of PREE-T. Correlation coefficients between the PREE-T total score and DASH disability/symptom and work sub-parameters were 0.636 and 0.461, respectively. PREE-T pain and function sub-parameters correlated with related sub-parameters of the SF-36 bodily pain (r = - 0.721) and physical functioning (r = - 0.263). CONCLUSION: The Turkish version of the PREE is a valid and reliable outcome measure for assessing patients with elbow disorders. It is recommended to be used in research and clinical settings. Key Points • The Turkish version of the Patient-Rated Elbow Evaluation was successfully translated into Turkish and validated in a population with various elbow pathologies according to established guidelines • The Turkish version of the Patient-Rated Elbow Evaluation has high internal consistency and test-retest values • The Turkish version of the Patient-Rated Elbow Evaluation is valid and reliable.

Cross-Cultural Adaptation, Validity, and Reliability Study of the Turkish Version of the Back Pain Functional Scale.

Study Design: Prospective study. Purpose: To investigate the cross-cultural adaptation, validity, and reliability of the Turkish version of the Back Pain Functional Scale (BPFS). Overview of Literature: Low back pain is a common disorder in the population that negatively affects the patient's daily, professional, and social life. Self-report questionnaires are important to precisely evaluate back pain and making better and appropriate treatment decisions. Currently, there are several questionnaires for investigating mobility in patients with low back pain. Methods: We recruited 360 patients with chronic low back pain. For assessing the reliability of the scale, we performed test-retest and internal consistency analyses. Test-retest analysis was performed using intraclass correlation coefficient (ICC). Internal consistency was analyzed by calculating Cronbach's alpha value. Construct validity of the questionnaire was evaluated by comparing total scores on the BPFS with those on Roland Morris Disability Questionnaire (RMDQ) and Oswestry Disability Index (ODI) using Pearson's correlation coefficient analysis. Results: Cronbach's alpha value was 0.910, indicating high internal consistency. The test-retest reliability was excellent (ICC, 0.958; 95% confidence interval, 0.710-0.908). No floor or ceiling effects were observed. Factor analysis indicated that the scale had a single-factor structure. Pearson correlation coefficient was -0.669 when BPFS was compared with RMDQ and -0.701 when compared with ODI. These values indicate a significant correlation of BPFS with RMDQ and ODI. Conclusions: These data indicate the validity and reliability of the Turkish version of the BPFS.

Effects of Kinesio Taping on the Relief of Delayed Onset Muscle Soreness: A Randomized, Placebo-Controlled Trial.

OBJECTIVE: The purpose of this study was to examine the effects of Kinesio taping (KT) on delayed onset muscle soreness. DESIGN: Randomized controlled study. SETTING: Clinical laboratory. PARTICIPANTS: Fifty-four nonathletic volunteers were assigned randomly to KT (n = 27) and placebo KT (n = 27) groups. INTERVENTIONS: The intense exercise protocol consisted of 100 consecutive drop jumps from a 0.60-m-high platform. Kinesio tape was applied with the fan technique on the quadriceps muscles in the KT group. The placebo KT group received the Kinesio tape with no technique and tension. MAIN OUTCOME MEASURE: Muscle soreness, maximal isometric quadriceps muscle strength, vertical jump height, and blood analyses (creatine kinase, lactate dehydrogenase, myoglobin, and C-reactive protein) were measured preexercise, immediately postexercise, 48 hours postexercise, and 72 hours postexercise. RESULTS: There was a significant effect of time in all outcome measures (P < .05) except serum C-reactive protein level (P > .05). The intensity of muscle soreness was significantly lower in the KT group relative to the placebo KT group at 72 hours postexercise (P = .01). The serum creatine kinase level was significantly higher in the KT group compared with the placebo KT group at 72 hours postexercise (P = .01). There were no statistically significant differences between groups for the other outcome measures (P > .05). CONCLUSIONS: These findings indicate that KT intervention following the intense exercise protocol reduced muscle soreness. However, it had no effect on maximal quadriceps isometric strength and vertical jump height or serum lactate dehydrogenase, myoglobin, and C-reactive protein levels. Furthermore, KT application after intense exercise also increased serum creatine kinase levels.

Cross-Cultural Adaptation, Validity, and Reliability Study of the Turkish Version of Back Performance Scale.

STUDY DESIGN: Validation of a performance scale. OBJECTIVE: The purpose of this study is to investigate adaptation, validity, and reliability of the Turkish version of the Back Performance Scale (BPS). SUMMARY OF BACKGROUND DATA: Low back pain affects people of all ages and causes pain, disability, and psychosocial problems. BPS is a condition-specific performance measure of activity limitation in patients with low back pain. The purpose of this study is to investigate the cross-cultural adaptation, validity, and reliability of the Turkish version of the BPS. METHODS: The study included 180 patients with low back pain. For the reliability assessment of the scale, test-retest, and internal consistency analyses were performed. The results of the test-retest analysis were analyzed by Intraclass Correlation Coefficient (ICC) method. For the internal consistency, Cronbach Alpha value was calculated and to construct validity, total points of the BPS were compared with the total points of Roland Morris Disability Questionnaire (RMDQ) and Oswestry Disability Index (ODI) using Pearson correlation coefficient analysis. RESULTS: BPS was found to have high internal consistency (Cronbach alpha value 0.827). Test-retest results were found highly correlated (range from 0.723 to 0.899). Factor analysis indicated that the scale had one factor. BPS is well correlated with RMDQ and ODI (Pearson correlation coefficient with RMDQ 0.576 and with ODI 0.603). CONCLUSION: The Turkish version of BPS is valid and reliable. LEVEL OF EVIDENCE: 3.
