Publication Adaptation, Reliability, and Validation of the Turkish Version of the Bad Sobernheim Stress Questionnaire-Deformity in Patients With Adolescent Idiopathic Scoliosis(Wolters Kluwer Health, 2023) Akçay, Burçin; Kuru Çolak, Tuǧba; APTİ, ADNANBackground:There is a limited number of disease-specific outcome measurement scales in Turkish, which can be used for individuals with adolescent idiopathic scoliosis (AIS). The aim of this study was to translate, adapt, and evaluate the validity and reliability of the Turkish version of the Bad Sobernheim Stress Questionnaire-Deformity (TRv.BSSQD) questionnaire in Turkish patients with AIS.Objective(s):After the translation and back-translation process, the TRv.BSSQD and Scoliosis Research Society-22 questionnaires were completed in face-to-face interviews with 49 patients with AIS. The TRv.BSSQD questionnaire was readministered to the same patients 2 weeks later to assess test-retest reliability.Results:The Cronbach alpha value calculated for internal reliability was 0.806. The intraclass correlation coefficient values of the items of the TRv.BSSQD ranged from 0.809 (P < 0.001) (question 8) to 0.955 (P < 0.001) (question 7). The test-retest correlation coefficient for the item-total score was 0.960 (P < 0.001). Validity analysis showed a significantly positive correlation between the TRv.BSSQD total score and pain, self-image, and mental subgroup and the total scores of the SRS-22r scale (P < 0.05).Conclusions:This patient-reported outcome instrument, the TRv.BSSQD, showed good internal consistency, good reliability with test-retest analysis, and construct validity, suggesting that it is an appropriate assessment instrument for Turkish patients with AIS.Publication Comparison of Motor Proficiency and Functional Ambulation in Duchenne Muscular Dystrophy With Healthy Peers(Taylor & Francis Ltd., 2020) Yıldız, Şulenur; Şahin, Sedef; Bulut, Numan; Tunca Yılmaz, Öznur; Karaduman, Aynur Ayşe; AKEL, BURCU SEMİNAims:The study was aimed to investigate the difference between boys with Duchenne muscular dystrophy (DMD) and healthy peers in terms of gross and fine motor proficiency, and determine the relationship between motor proficiency and ambulation. Methods:A total of 24 boys with DMD and 22 healthy peers were evaluated. Demographics and physical characteristics were recorded. The Bruininks Oseretsky Test of Motor Proficiency-Short Form (BOTMP-SF) was administered to evaluate gross and fine motor proficiency in both groups. The 6-minute walk test (6MWT) was performed to evaluate functional walking capacity and North Star Ambulatory Assessment (NSAA) was used to determine ambulatory status of boys with DMD. Results:The gross motor proficiency score was significantly lower in boys with DMD (p = 0.001). No difference was found between the groups in terms of fine motor proficiency (p = 0.962). The gross motor function of BOTMP-SF was significantly related to 6MWT distance (r = 0.696,p = 0.001) and NSAA (r = 0.738,p = 0.001). No relationship was found between BOTMP-SF fine motor proficiency and 6MWT distance (r = 0.210,p = 0.361), and NSAA (r= -0.020,p = 0.928). There were significant correlations between running speed and agility with 6MWT distance (r = 0.585,p = 0.005) and NSAA (r = 0.650,p = 0.056). Conclusions:Boys with DMD were more affected in aspects of gross motor proficiency than healthy peers, while fine motor proficiency were found same. The gross motor proficiency was found more related to the level of ambulation.Publication Cross-Cultural Adaptation, Reliability, and Validity of a Turkish Version of the Work Rehabilitation Questionnaire (WORQ-Turkish)(Springer Plenum, 2021) Aran, Orkun Tahir; Abaoğlu, Hatice; Çağlar, Gamze Ekici; AKEL, BURCU SEMİN; Aki, Esra; Karahan, Sevilay; Kayıhan, HülyaPurposeThe Work Rehabilitation Questionnaire (WORQ) is an instrument based on the International Classification of Functioning Vocational rehabilitation core set. The aim of this study was to analyze the validity, reliability and cross-cultural adaptation of the WORQ to Turkish and evaluate its psychometric properties.MethodsThe cross-cultural adaptation and translation procedures were conducted following Beaton's guidelines. The test-re-test reliability was examined by Spearman Brown Coefficient (split half analysis), internal consistency was examined by Cronbach's alpha. Criterion related validity of the WORQ was determined by Beck Depression Inventory using Pearson correlation coefficient and known group differences regarding age, gender, work and educational levels using one-way ANOVA and t test. Construct validity was examined by confirmatory factor analysis using AMOS.ResultsTwo hundred and fifty-seven participants with disabilities were included to the study from seven different provinces of Turkey. The WORQ-Turkish showed excellent internal consistency (0.906), good test-retest reliability (0.811), and good construct validity (good model fit indices). Criterion related validity analysis showed medium correlations between WORQ and Beck Depression Inventory (p < 0.001), however there were no statistical significant differences regarding known group parameters (p > 0.05).ConclusionsIn this study, the cross-cultural adaptation, and validity and reliability of WORQ-Turkish self-reported version were examined and the results indicated that WORQ-Turkish was a valid and reliable scale for analyzing vocational rehabilitation process of people with disabilities.Publication Determining the Relationship Between the Impairment of Selective Voluntary Motor Control and Gait Deviations in Children With Cerebral Palsy Using Simple Video-Based Analyses(Elsevier Ireland Ltd., 2021) Sardogan, Cansu; Muammer, Rasmi; AKALAN, NAZİF EKİN; Sert, Rukiye; Bilgili, FuatBackground: The impairment of selective voluntary motor control (SVMC) in children with cerebral palsy (CP) has been shown to correlate with their gait characteristics using complex 3D gait analysis systems (3DGA); however, this relationship has not been investigated using simple video-based observational gait analysis (VBOGA). The aim of this study was to determine the relationship between VBOGA and SVMC of the lower extremities in children with CP. Methods: Forty-two CP children 10.9 +/- 5.7 years old with Gross Motor Function Classification System (GMFCS) levels I-III participated in the study. Their gait characteristics were assessed using the Edinburgh Visual Gait Score (EVGS), and selective voluntary motor control was tested using the Selective Control Assessment of the Lower Extremity (SCALE). Spearman's rho correlation test with Cohen's classification were used in the statistical analyses. Results: The GMFCS levels (r = 0.604, p < 0.001), foot clearance (r = -0.584. p < 0.001), and maximum ankle dorsiflexion (r = -0.567, p < 0.001) during the swing phase had strong correlations with total SCALE scores. There was also a moderate correlation between total SCALE scores and total EVGS (r = -0.494, p < 0.001), knee extension in the terminal swing phase (r = -0.353, p < 0.001), peak sagittal trunk position (r = -0.316, p < 0.005), and maximum lateral shift (r = -0.37, p < 0.001). Conclusion: Impaired lower extremity SVMC was noticeably related to the foot and ankle movements in the swing phase and initial stance during walking as well as the total EVGS scores and sagittal and frontal trunk movements. The SCALE correlations with VBOGA were similar those observed in the complex 3DGA in the literature; therefore, we suggest that SVMC impairment of gait could be evaluated using simple VBOGA. These findings may help to tailor physical therapy programs for CP children to increase their motor control and walking quality.Publication The Effect of Kinesiophobia on Physical Activity, Balance, and Fear of Falling in Patients with Parkinson's Disease(Taylor & Francis Inc., 2022) Oğuz, Semra; UZUNOĞLU, GAMZE ERTÜRK; Polat, Mine Gülden; Apaydın, HülyaPurpose Kinesiophobia is defined as the fear of movement and activity resulting from a feeling of vulnerability to painful injury or re-injury. This study aimed to determine the effect of kinesiophobia on physical activity, balance, and fear of falling in patients with Parkinson's disease. Methods The study, which was designed as a cross-sectional type, was conducted with 86 patients with Parkinson's disease (age 61.25 SD [9.72] years old) by face-to-face interviews with the patients. The Tampa Scale of Kinesiophobia, International Physical Activity Questionnaire-Short Form, Berg Balance Scale, Falls Efficacy Scale, Visual Analog Scale - Fear of Falling, Unified Parkinson's Disease Rating Scale - motor score, and the Hoehn and Yahr scale were used to evaluate the patients. Results Patients with Parkinson's disease who had high levels of kinesiophobia had lower levels of physical activity, worse balance, and higher disease severity and fear of falling. A correlation was found between the Tampa Scale score and physical activity, balance, fear of falling, falls efficacy, and disease motor score (p r = -0.38, -0.54, 0.67, 0.57, and 0.37, respectively). According to multiple linear regression analysis, kinesiophobia explained the dependent variables to varying degrees ranging from 13% to 44% (p < .001). Conclusions Patients with Parkinson's disease may have kinesiophobia. Rehabilitation programs to support functional capacity for these patients should be developed considering the presence of kinesiophobia.Publication The Effect of Wearing High Heels on Lower Extremity Kinematics During Walking for Female with Hypermobility(Elsevier Ireland Ltd., 2023) AYAN, BUSE; AKALAN, NAZİF EKİN; ÖNERGE, KÜBRA; KUCHIMOV, SHAVKAT; EVRENDİLEK, HALENURPublication Effects of High Intensity Interval Training and Sprint Interval Training in Patients With Asthma: A Systematic Review(Taylor & Francis Ltd, 2022) UZUNOĞLU, GAMZE ERTÜRK; Günday, Çiçek; EVRENDİLEK, HALENUR; Sağır, Kübra; Aslan, Göksen KuranObjective The aim of this study is to review the effects of high-intensity interval training (HIIT)/sprint interval training (SIT) on asthma symptoms, cardiorespiratory functions, and other variables among asthmatic patients. Data sources Randomized controlled trials published between January 2000 and January 2021 were searched in PubMed/MEDLINE, Web of Science, and Cochrane Library databases. Study selections Following pre-specified inclusion criteria, this review included 7 randomized controlled studies that compare HIIT/SIT as an intervention with any other intervention and/or control group. Results Of the included studies only four reported the chronic phase effects of the HIIT/SIT protocols. HIIT and SIT protocols applied in studies differ. HIIT improved forced expiratory volume in 1 s (FEV1) in the acute phase and maximal oxygen consumption (VO2max) in the chronic phase in the asthmatic patients (p < 0.05). Conclusion To our knowledge, our systematic review is the first study evaluating the effects of HIIT/SIT protocols on asthma patients. HIIT/SIT protocols have beneficial effects on asthma patients. In order to better understand the results of these training procedures, studies that will be designed with high methodology are needed.Publication The Effects of Improvement in Upper Extremity Function on Gait and Balance in Children With Upper Extremity Affected(Elsevier Ireland Ltd., 2024) Leblebici, Gökçe; Tarakcı, Ela; Kısa, Eylül Pınar; AKALAN, NAZİF EKİN; Kasapçopur, ÖzgürBackground: This study aimed to investigate the effects of functional improvement in the upper extremity on gait and balance in children with upper extremity affected. Research question: What are the effects of functional improvement in the upper extremity on gait and balance in children with upper extremity affected? Methods: Eighteen children with a diagnosis of rheumatologic diseases and 15 healthy children were evaluated with Shriners Hospital Upper Extremity Assessment, Jebsen-Taylor Hand Function Test, Abilhand Rheumatoid Arthritis Scale, 10-meter walk test and Childhood Health Assessment Questionnaire. For static balance assessment, the Biodex Balance was used. Ground reaction forces (peak forces (heel strike and push-off) and minimum force (loading response), single-limb support duration, Center-of-Force displacement and walking speed were evaluated with the Sensor Medica. Arm swing was evaluated with the Kinovea 2D motion analysis. Results: Before treatment, single-limb support duration and push-off force was higher and center-of-force displacement was lower on affected side compared to unaffected side in rheumatologic group. After the 6week rehabilitation program, upper extremity function, quality of life and functional gait score improved. Single-limb support duration decreased on affected side and increased on unaffected side. On affected side, pushoff force decreased. The arm swing parameters were similar before and after treatment. Significance: Improving upper extremity function can help with gait balance by decreasing the difference in walking and balance parameters between the affected and unaffected sides and providing for more symmetrical weight transfer.Publication Effects of Pilates Exercises on Idiopathic Scoliosis: A Scoping Review of the Literature(Springer, 2023) Çolak, Tuğba Kuru; Akçay, Burçin; APTİ, ADNANPurpose Scoliosis is a deformity involving changes in three planes. These changes include lateral curvature in the frontal plane, changes in physiological thoracic kyphosis and lumbar lordosis angles in the sagittal plane, and rotation of the vertebrae in the transverse plane. The aim of this scoping review was to review and summarize the available literature to determine whether Pilates exercises are an effective treatment for scoliosis.MethodsThe Cochrane Library (reviews, protocols, trials), PubMed, Web of Science, Ovid, Scopus, PEDro, Medline, CINAHL (EBSCO), ProQuest, and Google Scholar electronic databases were used to search for published articles from inception to February 2022. All the searches included English language studies. Keywords were determined as "scoliosis and Pilates" or "idiopathic scoliosis and Pilates", "curve and Pilates", "spinal deformity and Pilates."Results Seven studies were included; one study was a meta-analysis study, three studies compared Pilates and Schroth exercises, and three applied Pilates exercises in combined therapy. The studies included in this review used outcome measurements of Cobb angle, ATR, chest expansion, SRS-22r, posture assessment, weight distribution, and psychological factors such as depression.ConclusionsThe results of this review suggest that the level of evidence regarding the effect of Pilates exercises on scoliosis-related deformity is very limited. Pilates exercises can be applied to reduce asymmetrical posture in individuals with mild scoliosis with reduced growth potential and progression risk.Publication Gait Characteristics and Effects of Early Treadmill Intervention in Infants and Toddlers with Down Syndrome: A Systematic Review(Taylor & Francis Ltd., 2022) Kınacı-Biber, Esra; ÖNERGE, KÜBRA; Mutlu, AkmerPurpose The aim of this study was to evaluate gait characteristics, and the effectiveness of treadmill interventions on gait in infants and toddlers with Down syndrome (DS). Materials and Methods A comprehensive search was performed on six databases for evidence published up to November 2020 for articles related to infants and toddlers with DS. The Clinical Appraisal Skills Programme Checklist assessed the methodological quality. Strength of evidence were evaluated Sackett's level. Results Nine articles analyzing instrumental gait met the inclusion criteria. Of these, 4 compared DS and typically developing (TD), and 5 included treadmill training interventions for DS. Kinematic analysis was applied in 8 studies and all articles presented evaluations at different times according to the walking experience. Analysis with EMG was used in only one of the intervention articles and in 3 of the 4 comparative articles. Conclusions Although similar improvements are seen in spatiotemporal parameters for toddlers with typical development and those with DS, the decrease in step width is not similar for DS. Early treadmill training can have a positively effect on the gait characteristics of DS infants. Further research should focus on the acquisition of gait characteristics, long-term evaluations, kinetics and EMG data, for these children.Publication Increased Femoral Anteversion May Not Cause Hip Abductor Muscle Weakness During Walking(Elsevier Ireland Ltd., 2023) APTİ, ADNAN; AKALAN, NAZİF EKİN; KUCHIMOV, SHAVKAT; Temelli, YenerPublication Intraoperative Testing of Passive and Active State Mechanics of Spastic Semitendinosus in Conditions Involving Intermuscular Mechanical Interactions and Gait Relevant Joint Positions(Elsevier, 2020) Kaya, Cemre S.; Bilgili, Fuat; AKALAN, NAZİF EKİN; Yücesoy, Can A.In cerebral palsy (CP) patients suffering pathological knee joint motion, spastic muscle's passive state forces have not been quantified intraoperatively. Besides, assessment of spastic muscle's active state forces in conditions involving intermuscular mechanical interactions and gait relevant joint positions is lacking. Therefore, the source of flexor forces limiting joint motion remains unclear. The aim was to test the following hypotheses: (i) in both passive and active states, spastic semitendinosus (ST) per se shows its highest forces within gait relevant knee angle (KA) range and (ii) due to intermuscular mechanical interactions, the active state forces elevate. Isometric forces (seven children with CP, GMFCS-II) were measured during surgery over a range of KA from flexion to full extension, at hip angle (HA) = 45 degrees and 20 degrees, in four conditions: (I) passive state, (II) individual stimulation of the ST, simultaneous stimulation of the ST (III) with its synergists, and (IV) also with an antagonist. Gait analyses: intraoperative data for KA = 17-61 degrees (HA = 45 degrees) and KA = 0-33 degrees (HA = 20 degrees) represent the loading response and terminal swing, and mid/terminal stance phases of gait, respectively. Intraoperative tests: Passive forces maximally approximated half of peak force in condition II (HA = 45 degrees). Added muscle activations did increase muscle forces significantly (HA = 45 degrees: on average by 42.0% and 72.5%; HA = 20 degrees: maximally by 131.8% and 123.7%, respectively in conditions III and IV, p < 0.01). In conclusion, intermuscular mechanical interactions yield elevated active state forces, which are well above passive state forces. This indicates that intermuscular mechanical interactions may be a source of high flexor forces in CP. (C) 2020 Elsevier Ltd.

The purpose of this study was to examine the effect of the task-orientated rehabilitation program (ToRP) on motor skills of children with childhood cancer. Following the consort guideline, 93 children (49 males and 44 females) with pediatric cancer were randomized to either study (n = 52; 12.35 ± 3.43 years) or control (n = 41; 11.89 ± 3.56 years) groups. The study group received ToRP, and the control group received a home-based therapeutic strategies program for 20 sessions. Motor skill outcomes were assessed with Bruininks-Oseretsky Test of Motor Proficiency, Short Form (BOTMP-SF) by assessor who was blind to group allocation and interventions. The groups were homogenous in terms of demographic characteristics and motor skills. The study group showed a significant increase in both gross and fine motor skills (P values for all subtests: P 0.001), whereas running speed, bilateral coordination, strength, response speed and visual motor control did not show significant improvement with the control group (P > 0.05). The ToRP appears to provide beneficial effects in improving motor skills at the early stages of rehabilitation for children with childhood cancer.Publication Kinematic Analysis of Walking of Hypermobile and Non-Hypermobile Individuals with Heavy Backpack(Elsevier Ireland Ltd., 2023) OPAN, İREM; Uzunoğlu, Gamze Ertürk; AKALAN, NAZİF EKİN; ÖNERGE, KÜBRA; KUCHIMOV, SHAVKAT; EVRENDİLEK, HALENURPublication Occupational Self-Perception Level Effects on the Development of Kinesiophobia in Individuals With Total Knee Arthroplasty(Elsevier, 2023) Yılmaz, Güleser Güney; AKEL, BURCU SEMİN; SAİTOĞLU, YELİZ SEVİMLİ; Akı, EsraIntroduction: The development of kinesiophobia after Total Knee Arthroplasty (TKA) has been one of the important issues. However, the early results and the presence of kinesiophobia before surgery have not been adequately investigated. In addition, the effects of factors such as pain perception, postoperative pain level, and demographic characteristics were mentioned. However, occupational factors such as occupational expectations and occupational self-perception level have not been adequately investigated.Methods: Each assessment tool was administered three times: once on the first day of the preoperative period and then again at the third and sixth weeks after the surgery. The assessment tools employed were the Knee Injury and Osteoarthritis Outcome Score, Tampa Scale for Kinesiophobia, Occupational Self Assessment, and Timed Up and Go test. To analyze the differences in Tampa Scale for Kinesiophobia scores, a one-way ANOVA was con-ducted. Subsequently, the patients were categorized into two groups based on their level of kinesiophobia: high and low. Independent sample t-tests were employed to compare continuous and normally distributed data be-tween the two groups, while the Mann-Whitney U test was used for non-normally distributed data. The Pearson correlation coefficient was utilized to assess the relationship between continuous data, whereas the Spearman rank-order correlation was employed for non-normally distributed data. Results: High levels of kinesiophobia were identified in individuals both prior to and following surgery. Signif-icant differences were observed between the high and low kinesiophobia groups in terms of the mean OSA Competency (p < 0.05). However, no statistically significant differences were found between the groups in relation to the other evaluation scores during the follow-up periods. Furthermore, a negative correlation was observed between TSK score and OSA Competence results (p < 0.05).Conclusion: Occupational self-perception levels effect the level of kinesiophobia in individuals with TKA and high rates of kinesiophobia observed before the surgery intensified after the surgery, especially in the early period. It may be necessary to focus more on factors such as individual factors, individuals' values, habits, and beliefs.Publication The Relationship of One Leg Standing Duration to GMFM Scores and to Stance Phase of Walking in Children with Hemiplegic Cerebral Palsy(Taylor & Francis, 2021) UZUNOĞLU, GAMZE ERTÜRK; AKALAN, NAZİF EKİN; EVRENDİLEK, HALENUR; YILMAZ, GÜLŞAH KARACA; Bilgili, FuatBackground: Lack of stability during stance negatively impacts gait and motor function for children with unilateral cerebral palsy. Improving stability and balance are the focus for gait rehabilitation). The One-Leg-Standing-Test may give valuable information about motor function and stability of stance for patients with unilateral cerebral palsy. Objective: This study aimed to investigate the relationship between the One-Leg-Standing-Test and the gross-motor-function-measurement and single-limb support time. Methods: The study included 18 patients with unilateral cerebral palsy (age 11.08 [SD 2.84] years old). The One-Leg-Standing-Test and pedobarographic evaluation were performed. Sections D and E of the gross-motor-function-measurement were assessed, and in pedobarographic evaluation, the single-limb support time (the total duration of mid-stance and terminal-stance during walking) was calculated to describe stability during stance. Results: For patients, the One-Leg-Standing-Test scores and single-limb support time values were lower on the affected side than on the unaffected side. The One-Leg-Standing-Test was correlated with single-limb support time (p = .02, r = 0.60) and section E (p < .01, r = 0.59) values. The One-Leg-Standing-Test was also correlated to total stance phase and section D. Conclusion: The One-Leg-Standing-Test gives valuable information about gross-motor-function but cannot be substituted for motor function tests. The single-limb support time value may be used to describe stability in stance during walking.Publication Time-Use, Occupational Balance, and Temporal Life Satisfaction of University Students in Turkey During Isolation Period of COVID-19(Taylor & Francis Australia, 2022) Salar, Sinem; Pekçetin, Serkan; Günal, Ayla; AKEL, BURCU SEMİNPeople all over the world have needed to adapt to social distancing, movement restrictions, and change in life routines due to Coronavirus disease 19 (COVID-19). This study aimed to explore the relationships between time-use, occupational balance, and temporal life satisfaction of university students in Turkey during the social isolation period due to the COVID-19 pandemic. The study was conducted online in May 2020, with 128 university students of a Turkish university with the mean age of 20.27 +/- 1.49 years (Min. 18 - Max. 26 years old) from 37 cities. The measures used were the Occupational Balance Questionnaire (OBQ), the Temporal Satisfaction with Life Scale (TSWLS), and a customized question about the time-use of the students in specific occupational domains. The results indicated that individuals with lower occupational balance had less present life satisfaction (p < .001). While the time allocated to study lessons, socialization, and exercise had small positive correlations with OBQ (p <.01), watching TV had a negative correlation with OBQ (p <.05) and with 'present TSWLS' (p <.01). The mean value of 'present TSWLS' (15.45 +/- 7.54) was lower than 'past TSWLS' (21.57 +/- 6.27) and 'future TSWLS' (22.64 +/- 4.60). Evaluation of occupational balance and the time use patterns of university students during the isolation periods could be important due to its relationship with life satisfaction. This issue raises the potential need for preventive occupation-based interventions to address the mental health of the community.Publication Translation, Psychometric and Concept Analysis of the Occupational Balance-Questionnaire Based on a Turkish Population(Taylor & Francis Inc., 2021) Bahadır, Zeynep; Yaran, Mahmut; Özkan, Esma; Ekici, Gamze; Huri, Meral; AKEL, BURCU SEMİNOccupational balance is a crucial concept in occupational therapy, accepted as a key component of health and well-being. The Occupational Balance-Questionnaire (OB-Quest) is designed as a standardized instrument to assess occupational balance. This study investigated the validity and reliability of the OB-Quest Turkish, which consisted of translation, cross-cultural adaptation, and analysis psychometric properties phases. The factor structure of the OB-Quest indicated a good model fit. The criterion-related validity showed a positive correlation with Beck Depression Inventory and a negative correlation with the 12-item Short Form Survey. The OB-Quest-Turkish showed questionable internal consistency and an excellent correlation between test-retest.Publication Translation, Reliability and Validity of the Turkish Version of Scoliosis Japanese Questionnaire-27 in Adolescent Idiopathic Scoliosis(Springer, 2023) Çolak, Tuğba Kuru; APTİ, ADNAN; Çolak, İlker; Akçay, Burçin; Dereli, Elif ElçinPurposeDisease-specific scales which evaluate QoL are needed to evaluate treatment outcomes, and to compare the effects of different treatments. The outcome measures evaluating quality of life in adolescent idiopathic scoliosis are limited. The purpose of this study was to examine the validity and reliability of the Turkish version of the Scoliosis Japanese Questionnaire-27 (SJ-27) in adolescent idiopathic scoliosis.MethodsThe SJ-27 questionnaire was translated into Turkish and 61 female patients filled out the translated version (TRv.SJ-27) twice to measure the test-retest reliability of the scale. Internal reliability of the questionnaire was estimated using Cronbach's alpha coefficient. The intraclass correlation coefficient was analysed for each item. Discriminant validity and convergent validity were determined by correlations with Cobb angle, ATR and the SRS-22r scale.ResultsThe mean Cobb angle was 25.8 degrees and the ATR angle was 8.8 degrees. Cronbach's alpha value was estimated as 0.935. The test-retest correlation coefficient for the item-total score was 0.877 (p = 0.000). Validity analysis showed a significantly positive correlation between the TRv.SJ-27 total score and Cobb and ATR angles, and a significantly negative relationship was found between the TRv.SJ-27 and SRS-22r scores.ConclusionsIt would be useful to use different outcome measures to assess the scoliosis-specific quality of life in clinical practice and research. The findings suggest that the Turkish version of Scoliosis Japanese Questionnaire-27 is a valid and reliable measure to assess Turkish patients with AIS.
