Thoracolumbar fascia and chronic low back pain in idiopathic lumbar scoliosis: an ultrasonographic study.

PURPOSE: The role of thoracolumbar fascia (TLF) in the development of chronic low back pain (CLBP) has growing evidence in the literature. Although CLBP is reported in individuals with idiopathic scoliosis (IS), its relationship with the TLF has yet not been established. This study aims to evaluate the TLF and its relationship with CLBP in IS. METHODS: A total of 60 individuals were included in the study. They were divided into three groups as follows: painful scoliosis (n = 20, age: 17.1 ± 3.7 years, Cobb angle: 15-43°), non-painful scoliosis (n = 20, age: 16.4 ± 3.4 years, Cobb angle: 15-45°), and healthy group (n = 20, age: 16.4 ± 4.7 years). Pain was evaluated using the short form of the McGill Pain Questionnaire. TLF thickness was evaluated on the lumbar region using ultrasonography. Trunk range of motion was assessed using a universal goniometer, and flexibility was assessed with sit-and-reach test. RESULTS: The thickness of the right TLF was greatest in the painful group, followed by non-painful (p = 0.007) and healthy (p < 0.001) groups. The thickness of the left TLF in the non-painful and painful groups was greater compared to the healthy group (p < 0.001). In the painful group, right TLF thickness was negatively correlated with trunk flexion/extension (r = -0.540, p = 0.014/r = -0.514, p = 0.020) and left rotation (r = -0.499, p = 0.025) but positively correlated with pain (r = 0.562, p = 0.01). CONCLUSIONS: Thickening of the TLF was observed in IS, whereby, in the presence of CLBP, it was further intensified. We suggest considering fascial thickening as a potential contributing factor to both pain and limited motion in relevant patients.

Does medial calcaneal wedge improve static balance and load distribution in young adults with pronated foot?

BACKGROUND: Foot orthoses changing the momentum in the subtalar joint are often recommended, especially in activities loading the foot, to bring the pronated foot posture closer to neutral. OBJECTIVES: To examine the immediate effect of medial heel wedge on static balance and load distribution in patients with increased pronation in the foot. STUDY DESIGN: Experimental study design. METHODS: Forty people with right dominant lower extremity participated in the study. For static balance assessment, we assessed ellipse surface, sway length, x-y mean, AP index, and Romberg ratio on 1 foot and measured load distribution as right-left foot and fore-hind foot with and without wedge. RESULTS: There was a difference between the parameters of the ellipse surface and the Romberg ratio on the left side in the measurements performed with and without wedge for static balance on the left side ( P < 0.05) while there was no difference in the remaining values ( P > 0.05). In the load distribution, the change in the right anteroposterior foot was significant, increasing the load on the forefoot with the wedge ( P < 0.05) while we observed no difference in the left fore-hind foot load distribution and right-left foot load distribution ( P > 0.05). CONCLUSION: Our study showed that for static balance, medial wedge can improve balance on the left side by decreasing sway, and for load distribution, the medial wedge changed the load distribution from back to front on the right side. These small differences in young healthy individuals are a preliminary indication that further studies are needed.

Smartphone use affects gait performance, spinal kinematics and causes spinal musculoskeletal discomfort in young adults.

BACKGROUND: Smartphone use may lead to alterations in spinal kinematics and musculoskeletal discomfort. OBJECTIVES: The aim of this study was to evaluate the effect of smartphone use on spinal kinematics, and to examine the relationship between smartphone addiction, spinal discomfort, and gait parameters. DESIGN: Cross-Sectional Study. METHODS: The study included 42 healthy adults aged 18-30 years. A photographic method was used for spinal kinematic evaluation in sitting, standing and at the end of a 3-min walk. GAITRite electronic walkway was used for spatiotemporal gait parameters. Smartphone addiction was evaluated with the Smartphone Addiction Scale - Short Version (SAS-SV). The Cornell Musculoskeletal System Discomfort Questionnaire (CMDQ) was used to evaluate feelings of discomfort and pain. RESULTS: There was an increase in head, cervical, and thoracic flexion angles while sitting, standing, and at the end of a 3-min walk. Similarly, an increase in thoracolumbar and lumbar flexion angles was observed only in the sitting position (p < 0.05). While using a smartphone during walking, cadence, walking speed, step length decreased, while step duration and double support duration increased (p < 0.05). A statistically significant correlation was determined between the SAS-SV and CMDQ scores (p < 0.05). CONCLUSION: The study showed that smartphone use has an impact on spinal kinematics during sitting, standing and at the end of a 3 min-walk, as well as on the spatiotemporal parameters of gait. This study suggest that smartphone addiction should be taken into consideration due to its potential to cause musculoskeletal discomfort and there may be a need to raise public awareness on this matter.

Dual Task Performance in Adolescents With Idiopathic Scoliosis.

Daily life activities commonly include many combinations of dual tasks. Although dual task ability has been studied in healthy young adults, dual task performance in adolescents with idiopathic scoliosis (IS) has not been explored. Our objective in this study was to investigate dual task performance in adolescents with IS. We paired 33 adolescents diagnosed with IS and 33 healthy control participants (age range: 11-17 years) and administered to both groups the Stroop Color and Word test as a measure of cognitive ability, and both the Expanded Timed Up and Go (ETUG) test and the Tandem Gait test as measures of motor tasks. During the motor tasks, we had participants spell five-letter words in reverse and count down by seven from a randomly presented number between 50 and 100 to assess their dual task (cognitive-motor) performance. All cognitive, motor, and dual cognitive-motor test scores differed significantly between the IS and healthy control groups. The time taken to complete all these tasks was longer for participants with IS compared with controls (p < .05). These results revealed diminished performances on dual cognitive-motor tasks among adolescents with IS when compared to peers without IS. Dual task performance is a new research paradigm in the scoliosis rehabilitation field, and it should be further investigated in future studies.

Investigation of body awareness and body image perception in patients with type 2 diabetes mellitus.

OBJECTIVES: The purpose of the study is to investigate body awareness and body image perception of patients with type 2 diabetes mellitus (T2DM) and to explore the association between clinical parameters and body awareness. METHODS: A total of 92 participants with T2DM (38 women and 54 men) aged 36-76 years were recruited. Biochemical measurements, including fasting blood glucose, postprandial blood glucose and hemoglobin A1c (HbA1c), were obtained from the patients' blood sample records. The Body Awareness Questionnaire (BAQ), Body Cathexis Scale (BCS) and Awareness Body Chart (ABC) were filled in by all subjects. RESULTS: Most participants had an above-average BAQ (81.5%) and BCS (87%) score. There was a significant correlation between body mass index and ABC pain subscale. HbA1c was significantly associated with the duration of diabetes and sleep-wake cycle, process domains and total BAQ score. The body awareness score for the lower leg and foot regions (ABC parts) was negatively correlated with fasting blood glucose and HbA1c levels, while body awareness in the foot region was negatively correlated with the duration of diabetes. There was no association between BCS and any clinical parameters. CONCLUSION: This study showed that body awareness is associated with diabetes-related clinical parameters, such as fasting blood glucose and HbA1c levels, and duration of diabetes in patients with T2DM. Following diabetes progression and an increase in blood glucose levels, body awareness tended to decrease, particularly in the lower leg and foot regions. These findings highlighted the importance of evaluating body awareness in patients with T2DM.

Reliability and validity of the Turkish version of the Kyphosis specific spinal appearance questionnaire in adolescents with moderate hyperkyphosis.

BACKGROUND: Hyperkyphosis cause poor posture, self-image, clinical or cosmetic deformity and well-being. Therefore, it is important to evaluate patients' perception of appearance in the rehabilitation process of individuals with hyperkyphosis. Recently Kyphosis Specific Spinal Appearance Questionnaire (KSAQ) has been developed for the assessment of appearance in hyperkyphosis patients. OBJECTIVE: To test validity and reliability of the Turkish version of the KSAQ. METHODS: Sixty-two patients with hyperkyphosis (curve above 50º), ranging in age between 12 and 22 years, was included in this study. Turkish translation/back-translation of the KSAQ was done by an expert committee. Internal consistency was analyzed using Cronbach's alpha. Validity was assessed by correlating the KSAQ with the Scoliosis Research Society-22 (SRS-22) Questionnaire. Its reliability was assessed using the test-retest method with two-week interval (Pearson's correlation coefficient) on 44 of these patients. RESULTS: Mean kyphosis angle was 60º ± 8.9º. KSAQ total scores showed excellent internal consistency (Cronbach's α = 0.944) and test-retest reliability (ICC = 0.890). Moderate to strong associations were found between KSAQ total score, each item scores and self-image domain of SRS-22 (r -0.299 to -0.730, p < 0.05). KSAQ total score had moderate correlation with SRS-22 total score (r 0.423, p 0.001). Overall, the KSAQ scale showed good validity. CONCLUSION: The Turkish version of the KSAQ is a reliable and valid patient reported outcome measure of kyphosis-specific aspects of appearance in patients with moderate hyperkyphosis.

The validity and reliability of the Turkish version of the 12-item Örebro musculoskeletal screening questionnaire (ÖMSQ-12-TR).

PURPOSE: The 12-item Örebro Musculoskeletal Screening Questionnaire (ÖMSQ-12) is a multidimensional questionnaire assessing general musculoskeletal problems. This study aimed to investigate its construct validity and reliability. MATERIALS AND METHODS: Confirmatory factor analysis (CFA) was performed for construct validity. The Tampa Scale for Kinesiophobia (TSK) and the SF-12 and Pain Numerical Rating Scale (P-NRS) were used for convergent validity. Reliability (ICC), internal consistency (Cronbach's alpha), reproducibility, and known-group validity were assessed. The cut-off value was measured. RESULTS: A total of n = 378 individuals (aged 35.7 ± 12.4 years, female = 73.3%) with a musculoskeletal problem participated in the study. P-NRS score of the individuals was 5. Results showed that a 3-factor model did fit well under CFA (χ2/df = 2.76 ≤ 3). The questionnaire had good reliability (ICC = 0.865) and internal consistency (α = 0.810). There were no floor or ceiling effects (<%15). Total ÖMSQ-12-TR scores had a correlation with the TSK, SF-12 and P-NRS (r = 0.303-0.609). The AUC for the risk of absenteeism from work was obtained as 0.738 (p < 0.001). The risk of absenteeism was high in individuals with an ÖMSQ-12-TR score of ≥57.5. CONCLUSIONS: The ÖMSQ-12-TR is a valid and reliable questionnaire that can be used in determining the risk of absenteeism in musculoskeletal disorders and is convenient for online use. CLINICAL TRIAL NUMBER: NCT04723615.

An investigation of sleep profiles in individuals with idiopathic scoliosis.

Objective: Sleep behaviors have not been well investigated in individuals with idiopathic scoliosis (IS). This study aimed to investigate sleep quality and daytime sleepiness in individuals with IS and investigate the relationship between sleep parameters and curve magnitude, trunk deformity severity, pain, and emotional status in adolescents with IS. Material and Methods: Ninety-one participants between the ages of 10 and 19 years with IS were included. Sleep quality was evaluated using the Pittsburgh sleep quality index (PSQI), and daytime sleepiness was assessed with Epworth sleepiness scale (ESS). Pain was assessed using the short-form McGill pain questionnaire; the presence or severity of depressive feelings was evaluated using the Beck depression scale. Results: The majority of the participants (64.8%) had poor sleep quality, while daytime sleepiness was within normal limits in most participants (85.7%).The frequency of participants without pain (52.7%) was similar to participants with pain (47.3%). The prevalence of participants with depressed mood was 35.2%. Participants with poor sleep quality were more likely to have a higher sensorial index (p<0.001), higher total pain scores (p=0.001), and less lumbar axial rotation (p=0.046). Higher pain (r=0.391), depression scores (r=0.234), and lower lumbar axial trunk rotation (r=-0.317) were associated with increased daytime sleepiness. Conclusion: We observed poor sleep quality and an association with pain in patients with IS. Curve magnitude had no adverse effect on sleep quality or daytime sleepiness. Therefore, the sleep profile and its association with pain should be considered during the rehabilitation process in patients with IS.

Kinesiophobia and its association with treatment choice in individuals with idiopathic scoliosis.

BACKGROUND: Previous studies have reported increased kinesiophobia in adults with degenerative scoliosis or adolescents who have undergone spinal surgery. However, little is known about the phenomenon of kinesiophobia among adolescents with idiopathic scoliosis (IS). OBJECTIVES: The aim of this study was to investigate levels of kinesiophobia and its association with treatment choice in IS. METHODS: The study included 98 IS patients with a mean age of 14 years and 20 healthy controls. Participants with IS were divided into groups based on treatment conditions, as follows: (1) untreated (n= 33); (2) treated with exercise (n= 32); and (3) treated with a brace (n= 33). Kinesiophobia was measured using the Tampa Scale for Kinesiophobia (TSK). Comparisons were made between four groups. RESULTS: Untreated participants with IS were found to have greater kinesiophobia than healthy controls (p< 0.001). Participants treated with a brace (p= 0.046) and exercise (p= 0.064) had similar kinesiophobia levels as the healthy control group. CONCLUSIONS: Kinesiophobia was found to be higher in adolescents with IS compared to healthy peers. Brace or exercise treatment both had a positive impact on kinesiophobia. These findings should be considered when organizing rehabilitation programs to achieve the best results for adolescents with IS.

Investigation of multidirectional hip range of motion and hip motion asymmetry in individuals with idiopathic scoliosis with different curve patterns.

BACKGROUND: While some studies of the asymmetry of lower limbs in individuals with idiopathic scoliosis exist, there is a need for multidirectional studies conducted on hip joint range of motion and its relationship to curve patterns in idiopathic scoliosis. OBJECTIVES: This study analyzes the hip joint range of multidirectional motions, hip motion asymmetry and investigates them according to curve patterns in individuals with idiopathic scoliosis. METHODS: The sample included 108 females with idiopathic scoliosis. Participants were divided into three groups: double curves, single thoracic curve and single lumbar curve. The range of hip flexion and extension, abduction and adduction, and internal and external rotations were assessed actively and passively with a universal goniometer. The range of motion, left-right asymmetry and the mid-points of the ranges of motion were analyzed. RESULTS: The passive range of the right hip abduction was higher in the thoracic curve group vs. the lumbar curve group. Active and passive ranges of hip extension were higher in the left hip vs. right hip. Active left-right asymmetry was higher than passive left-right asymmetry. CONCLUSION: Individuals with idiopathic scoliosis had different hip abduction motions according to curve pattern that originated from single curves. Left-right hip asymmetry was seen for the hip extension motion. Higher left-right asymmetry for active motion than passive motion in hip abduction may indicate a problem in motion perception in individuals with idiopathic scoliosis.

Hip-Focused Neuromuscular Exercise Provides Immediate Benefits in Foot Pronation and Dynamic Balance: A Sham-Controlled Cross-Over Study.

CONTEXT: Knowledge on how to utilize a kinetic chain approach in foot and ankle rehabilitation is important. OBJECTIVE: The aim of this study was to investigate the immediate effects of hip-focused neuromuscular exercise on foot pronation and single-leg neuromuscular control. DESIGN: Cross-over study. SETTING: University laboratory. PARTICIPANTS: This cross-over study included 44 asymptomatic volunteers with foot pronation. INTERVENTIONS: All participants performed (1) a hip-focused neuromuscular exercise and (2) a sham exercise in randomized order. MAIN OUTCOME MEASURES: Foot pronation was assessed by the navicular drop test, and lower-extremity neuromuscular control was assessed by the Modified Star Excursion Balance Test and frontal plane projection angle during single-leg squat before and after the experiments. RESULTS: Navicular drop test scores were significantly lower after the hip-focused neuromuscular exercise than after the sham exercise (mean difference [95% CI] = 2.84 [-1.08 to 6.77], P = .003). Modified Star Excursion Balance Test scores in the anterior (P = .008), posteromedial (P = .04), and posterolateral (P < .001) directions were significantly increased after hip-focused neuromuscular exercise. No statistically significant condition × time interaction was found for the frontal plane projection angle (P > .05). However, a main effect of time (P = .003) indicated that less dynamic knee valgus occurred during single-leg squat after both experiments. CONCLUSIONS: Hip-focused neuromuscular exercise produced immediate alterations in foot pronation and dynamic balance. Thus, the hip-focused neuromuscular exercise may be used to control foot posture in foot rehabilitation integrated with a kinetic chain approach and could be an effective prevention and treatment strategy.

Reliability and validity of Turkish version of the Scoliosis Japanese Questionnaire- 27 in patients with adolescent idiopathic scoliosis.

BACKGROUND: The aim of this study was to evaluate the reliability and validity of an adapted Turkish version of the Scoliosis Japanese Questionnaire- 27 (SJ- 27). METHODS: Translation and retranslation of the English version of the SJ- 27 was conducted, and all steps of the cross-cultural adaptation process were performed. The Turkish version of the SJ- 27, the Scoliosis Research Society-22 (SRS- 22) questionnaire and the Short Form-36 (SF- 36) were performed to 139 patients with AIS. Reliability was assessed using the test-retest method (Pearson's correlation coefficient); internal consistency was analyzed using Cronbach's alpha. Validity was assessed by correlating the SJ- 27 with the SRS- 22 questionnaire and SF- 36. RESULTS: The mean Cobb angles were 23.2 ± 8.3° and 19 ± 5.9° for thoracic and lumbar regions, respectively. The SJ- 27 showed excellent test/retest reliability with an Intraclass correlation coefficient of 0.99. Internal consistency of the SJ- 27 was found to be very good (Cronbach's alpha = 0.991). The SJ- 27 demonstrated very good construct validity with the SRS- 22 total score (r = 0.61). The similar domains of the SJ- 27 and SF- 36 questionnaire was correlated also in the study. CONCLUSIONS: The Turkish version of the SJ- 27 to measure health related quality of life in adolescent idiopathic scoliosis was found to have very good validity, excellent reliability, and high internal consistency.

Evaluation of upper extremity function and its relation to curve pattern in female adolescents with idiopathic scoliosis: a pilot study.

STUDY DESIGN: Cross-sectional and clinical measurement. OBJECTIVE: To evaluate upper extremity function and its relation to the curve pattern in idiopathic scoliosis. Postural alterations and trunk distortions-caused by three-dimensional deformity itself in idiopathic scoliosis-may lead to functional changes in the upper extremity of subjects. METHODS: Handgrip, pulp and lateral pinch strengths, hand dexterity, hand reaction time, coordination of upper extremity, upper extremity performance, throwing accuracy, and self-reported upper extremity disability were evaluated in 96 subjects. These subjects were divided into 3 groups: 47 with main thoracic curve pattern scoliosis (Lenke type 1), 31 with thoracolumbar/lumbar curve pattern scoliosis (Lenke type 5), and 18 unaffected (healthy control). Comparisons were performed between these three groups. RESULTS: The thoracic scoliosis group showed a significant decrease in concave lateral pinch strength, concave hand dexterity of turning, coordination of the upper extremities, and concave hand reaction time than the thoracolumbar/lumbar scoliosis group (p < 0.05). Bilateral handgrip strengths decreased in thoracic scoliosis group when compared to healthy controls. Healthy individuals demonstrated greater throwing accuracy than individuals with scoliosis. CONCLUSIONS: Upper extremity function was found to be affected based on the curve pattern. Individuals with main thoracic curves are likely to have deteriorated upper extremity function, especially for hand-specific motor skills, on the concave side, when compared to lumbar curves and healthy controls. LEVEL OF EVIDENCE: Level III.

Body Awareness and its Relation to Quality of Life in Individuals with Idiopathic Scoliosis.

An individual's body awareness depends on the integration of bodily signals from both inside and outside the body. The etiology of idiopathic scoliosis includes a variety of somatosensorial and biomechanical alterations that may affect an individual's body awareness. In this study, we investigated body awareness and its relation to quality of life among individuals with idiopathic scoliosis. We studied 96 participants with scoliosis and 71 healthy control participants. We evaluated both participant groups' body awareness using the Awareness-Body-Chart, and we assessed the quality of life of those with scoliosis using the Scoliosis Research Society-22 (SRS-22) questionnaire. The overall body awareness score and the body awareness values for the face, cervical/lumbar region, back, shoulder, upper arm, lower arm/elbow, hand, genital area, thigh/hip, lower leg, and foot were all found to be significantly lower among the participants with scoliosis than among healthy participants. Among participants with scoliosis, the body awareness value for the back region was positively correlated with pain, body image, mental health, and overall quality of life scores on the SRS-22, whereas the pain score on the Awareness-Body-Chart was negatively correlated with the function/activity, pain, mental health, and overall scores for the SRS-22. This study showed that participants with idiopathic scoliosis have poorer body awareness than control participants without scoliosis, and body awareness among participants with scoliosis was correlated with their self-reports of pain, body image, function, and mental health. These findings highlight the particular importance of body awareness to quality of life for individuals with scoliosis.

Effect of elastic scapular taping on shoulder and spine kinematics in adolescents with idiopathic scoliosis.

OBJECTIVE: The aim of this study was to investigate the short-term effects of scapular repositioning using an elastic taping technique on the three-dimensional (3-D) shoulder and thoracic kinematics during various activities of daily living (ADLs) in adolescents with idiopathic scoliosis (IS). METHODS: Shoulder and spine kinematics during five ADL movement tasks were assessed in 24 adolescents with IS (3 males and 21 females; mean age: 15.8 years; age range: 14-17 years) before and 15 min after elastic scapular taping. All the participants had a moderate curve magnitude (Cobb angle: 20°-45°), with a primary thoracic curve. A 3-D electromagnetic tracking system (Ascension Technology Corporation, Shelburne, VT, USA) was used to record 3-D shoulder and thoracic kinematics. ADL movement tasks included touching the mouth/drinking, touching the back, touching the contralateral shoulder, reaching upward, and bilateral 4-kg weight lifting. Two separate strips of elastic tape were applied using the same correction technique for each shoulder and scapular region to control scapular alterations in the resting position. RESULTS: Elastic scapular taping significantly improved scapular external rotation and scapular upward rotation. Similarly, humeral horizontal adduction, external rotation, thoracic flexion, and lateral bending significantly increased in the taped condition depending on the specific task (p<0.05). CONCLUSION: Elastic scapular taping can change scapular orientations on the convex and concave sides, thereby affecting upper extremity and trunk kinematics. Thus, the dynamic stability of the scapula increases to produce larger movements during functional activities. LEVEL OF EVIDENCE: Level IV, Therapeutic study.

Validation of the Turkish version of the Revised Foot Function Index for patients with foot and ankle disorders.

BACKGROUND: The revised Foot Function Index (FFI-R) is a multidimensional instrument that was developed to assess a patient's self-reported health-related foot function. The FFI-R is clinically useful and easy to apply, and it has comprehensive subscales assessing the pain, stiffness, psychosocial stress, disability, and activity limitations related to foot and ankle problems. The present study was conducted to validate the Turkish version of the FFI-R, and to demonstrate its use in a Turkish population with various foot and ankle problems. METHODS: The English version of the FFI-R was translated into Turkish, and then, it was administered to 124 patients (mean age of 39.9 years old) with foot and ankle problems and a mean symptom duration of 7.9 months. These patients completed two well-established foot and ankle-specific patient-reported outcome measures, the Foot and Ankle Outcome Score (FAOS) and the Manchester-Oxford Foot Questionnaire (MOX-FQ), and a general instrument, the 36-item Short Form Health Survey (SF-36). The test-retest reliability was evaluated using the intraclass correlation coefficient, and the internal consistency was measured using Cronbach's alpha. The construct validity of the FFI-R was assessed by correlating its subscales with the FAOS, MOX-FQ, and SF-36 subscales. RESULTS: The test-retest reliability of the FFI-R ranged between 0.84 and 0.97. The internal consistency was 0.97 for the overall FFI-R, and it ranged between 0.85 and 0.97 for the subscales. Significant correlations were obtained between the FFI-R subscales and the FAOS, MOX-FQ, and SF-36 subscales. CONCLUSIONS: The Turkish version of the FFI-R was found to be a reliable and valid instrument for measuring the foot and ankle-related functional disability and health status of Turkish patients with foot and ankle problems.

In-brace alterations of pulmonary functions in adolescents wearing a brace for idiopathic scoliosis.

BACKGROUND: Despite the common use of braces to prevent curve progression in idiopathic scoliosis, their functional effects on respiratory mechanics have not been widely studied. OBJECTIVE: The objective was to determine the effects of bracing on pulmonary function in idiopathic scoliosis. METHODS: A total of 27 adolescents with a mean age of 14.5 ± 1.5 years and idiopathic scoliosis were included in the study. Pulmonary function evaluation included vital capacity, forced expiratory volume, forced vital capacity, maximum ventilator volume, peak expiratory flow, and respiratory muscle strengths, measured with a spirometer, and patient-reported degree of dyspnea. The tests were performed once prior to bracing and at 1 month after bracing (while the patients wore the brace). RESULTS: Compared with the unbraced condition, vital capacity, forced expiratory volume, forced vital capacity, maximum ventilator volume, and peak expiratory flow values decreased and dyspnea increased in the braced condition. Respiratory muscle strength was under the norm in both unbraced and braced conditions, while no significant difference was found for these parameters between the two conditions. CONCLUSION: The spinal brace for idiopathic scoliosis tended to reduce pulmonary functions and increase dyspnea symptoms (when wearing a brace) in this study. Special attention should be paid in-brace effects on pulmonary functions in idiopathic scoliosis. CLINICAL RELEVANCE: Bracing seems to mimic restrictive pulmonary disease, although there is no actual disease when the brace is removed. This study suggests that bracing may result in a deterioration of pulmonary function when adolescents with idiopathic scoliosis are wearing a brace.
