Shoulder and Scapular Muscle Activity During Low and High Plank Variations With Different Body-Weight-Bearing Statuses.

ABSTRACT: Can, EN, Harput, G, and Turgut, E. Shoulder and scapular muscle activity during low and high plank variations with different body-weight-bearing statuses. J Strength Cond Res 38(2): 245-252, 2024-This study investigated the activation levels and activation ratios of shoulder and scapular muscles during low plank (LP) and high plank (HP) variations, with varying levels of body-mass support, including 4-point, 3-pod, and 2-point body-weight-bearing (BWB) statuses. The study was conducted with 21 healthy men (mean ± SD , 26 ± 6.5 years of age and 24.4 ± 2.4 kg·m -2 BMI). Ten different plank exercises were performed in a mixed order by changing elbow joint positions (LP and HP) and BWB statuses (2-point, 3-pod, and 4-point). Activation levels of the lower trapezius (LT), middle trapezius (MT), upper trapezius (UT), biceps brachii, triceps brachii, infraspinatus, and serratus anterior (SA) muscles were assessed with a surface electromyography device. Results of this study showed that elbow position changes resulted in higher LT ( p = 0.01) and TB ( p = 0.001) activation in HP exercises. In general, it was observed that an increase in BWB status was effective in increasing activation for the scapula and shoulder girdle muscles. The ratios of the UT muscle to the SA, LT, and MT muscles were less than 1 during side plank, bird dog, front reach, shoulder taps, and plank with shoulder external rotation exercises. High plank with toe touch exercise resulted in a marked increase in the UT activation. Therefore, it was concluded plank variations alter activation levels and activation ratios of shoulder and scapular muscles. Plank exercises may be used in shoulder rehabilitation and the progression in plank variations can be achieved by changing elbow position and BWB status based on individual requirements.

A snapshot of pediatric inpatients and outpatients with COVID-19: a point prevalence study from Turkey.

This multi-center point prevalence study evaluated children who were diagnosed as having coronavirus disease 2019 (COVID-19). On February 2nd, 2022, inpatients and outpatients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were included in the study from 12 cities and 24 centers in Turkey. Of 8605 patients on February 2nd, 2022, in participating centers, 706 (8.2%) had COVID-19. The median age of the 706 patients was 92.50 months, 53.4% were female, and 76.7% were inpatients. The three most common symptoms of the patients with COVID-19 were fever (56.6%), cough (41.3%), and fatigue (27.5%). The three most common underlying chronic diseases (UCDs) were asthma (3.4%), neurologic disorders (3.3%), and obesity (2.6%). The SARS-CoV-2-related pneumoniae rate was 10.7%. The COVID-19 vaccination rate was 12.5% in all patients. Among patients aged over 12 years with access to the vaccine given by the Republic of Turkey Ministry of Health, the vaccination rate was 38.7%. Patients with UCDs presented with dyspnea and pneumoniae more frequently than those without UCDs (p < 0.001 for both). The rates of fever, diarrhea, and pneumoniae were higher in patients without COVID-19 vaccinations (p = 0.001, p = 0.012, and p = 0.027).  Conclusion: To lessen the effects of the disease, all eligible children should receive the COVID-19 vaccine. The illness may specifically endanger children with UCDs. What is Known: • Children with COVID-19 mainly present with fever and cough, as in adults. • COVID-19 may specifically threaten children with underlying chronic diseases. What is New: • Children with obesity have a higher vaccination rate against COVID-19 than children without obesity. • Among unvaccinated children, fever and pneumoniae might be seen at a higher ratio than among vaccinated children.

Kinetic chain revisited: consensus expert opinion on terminology, clinical reasoning, examination, and treatment in people with shoulder pain.

BACKGROUND: The purpose of this study was to reach consensus on the most appropriate terminology and issues related to clinical reasoning, examination, and treatment of the kinetic chain (KC) in people with shoulder pain among an international panel of experts. METHODS: A 3-round Delphi study that involved an international panel of experts with extensive clinical, teaching, and research experience in the study topic was conducted. A search equation of terms related to the KC in Web of Science and a manual search were used to find the experts. Participants were asked to rate items across 5 different domains (terminology, clinical reasoning, subjective examination, physical examination, and treatment) using a 5-point Likert-type scale. An Aiken coefficient of validity (V) ≥0.7 was considered indicative of group consensus. RESULTS: The participation rate was 30.2% (n = 16), whereas the retention rate was high throughout the 3 rounds (100%, 93.8%, and 100%). A total of 15 experts from different fields and countries completed the study. After the 3 rounds, consensus was reached on 102 items: 3 items were included in the "terminology" domain; 17 items, in the "rationale and clinical reasoning" domain; 11 items, in the "subjective examination" domain; 44 items, in the "physical examination" domain; and 27 items, in the "treatment" domain. Terminology was the domain with the highest level of agreement, with 2 items achieving an Aiken V of 0.93, whereas the domains of physical examination and treatment of the KC were the 2 areas with less consensus. Together with the terminology items, 1 item from the treatment domain and 2 items from the rationale and clinical reasoning domain reached the highest level of agreement (V = 0.93 and V = 0.92, respectively). CONCLUSION: This study defined a list of 102 items across 5 different domains (terminology, rationale and clinical reasoning, subjective examination, physical examination, and treatment) regarding the KC in people with shoulder pain. The term "KC" was preferred and a agreement on a definition of this concept was reached. Dysfunction of a segment in the chain (ie, weak link) was agreed to result in altered performance or injury to distal segments. Experts considered it important to assess and treat the KC in particular in throwing or overhead athletes and agreed that no one-size-fits-all approach exists when implementing shoulder KC exercises within the rehabilitation process. Further research is now required to determine the validity of the identified items.

Cross-Cultural Adaptation of the University of Wisconsin Running Injury and Recovery Index in Turkish Runners.

CONTEXT: The University of Wisconsin Running Injury and Recovery Index (UWRI) was developed to evaluate the key elements that runners use to self-assess their own running ability following common running-related injuries. The aim of this study was to translate and culturally adapt the UWRI and to evaluate the psychometric properties of its Turkish version (UWRI-Tr) in runners. DESIGN: Prospective cohort study. METHODS: The study included 129 runners. The UWRI-Tr, the Lower Extremity Functional Scale, the Oswestry Disability Index, the Hip Outcome Score, the International Knee Documentation Committee Subjective Knee Evaluation Form, and the Foot and Ankle Ability Measure were applied for the validation purposes. Internal consistency, reliability, construct validity, and discriminant validity of the UWRI-Tr were tested. RESULTS: The test-retest reliability of the UWRI-Tr was excellent with an intraclass correlation coefficient of .85 and a Cronbach α value of .84. There was a small to strong correlation among the UWRI-Tr and Lower Extremity Functional Scale (r = .278), Oswestry Disability Index (r = -.744), Hip Outcome Score (r = .684), The International Knee Documentation Committee Subjective Knee Evaluation Form (r = .758), and Foot and Ankle Ability Measure (r = .498 and .767), indicating that its construct validity was appropriate for use with Turkish runners. CONCLUSIONS: The UWRI-Tr was shown to be a valid and reliable tool to use in clinical and research settings as a sport-specific measurement tool.

Evidence for taping in overhead athlete shoulders: a systematic review.

Taping is a popular approach and is often used as part of a multifactorial injury prevention programme for athletes. The aim of this study was to evaluate the current literature regarding the effects of shoulder taping in overhead athletes. Literature search was performed related to rotational range of motion (RoM), posterior shoulder tightness (PST), kinematics, muscular activity, acromiohumeral distance (AHD), proprioception, strength, and performance. Twenty studies were eligible. The majority of the applied taping methods were scapular and humeral head repositioning taping. Across all studies, there was limited to moderate evidence in favour of taping in overhead athletes with regard to rotational RoM, AHD, proprioception, and altering scapular kinematics, while taping did not enhance PST, muscular activity, shoulder strength, and performance. Therefore, the current evidence showed taping can alter some of the investigated factors that may have a therapeutic or preventive role. However, in the management of the athlete shoulder, taping-only approaches should not be focused on, and taping can be integrated in a more comprehensive approach for the overhead athletes.

Tender point examination with palpation in different shoulder pathologies: A retrospective study.

BACKGROUND: Shoulder pain is a common symptom for non-traumatic shoulder pathologies and affects 4.7-66.7% of entire population. Even with the latest technological advantages, palpation still is a cost and time efficient tool to evaluate the shoulder pathologies. Our aim was to investigate and compare palpation findings in different shoulder pathologies. METHOD: We used first assessments of impingement syndrome (IS) (n = 205), rotator cuff tear (RCT) (n = 185) and frozen shoulder (FS) (n = 210) patients who received treatment between 2010 and 2019 years. Two experienced physiotherapists palpated predefined points: long head of biceps brachii, pectoralis minor, lateral intermuscular septum, proximal tendons of extensor group. These points categorized into "proximal", "mid-proximal", "mid-distal", "distal", "irregular". We also grouped patients by their BMIs. RESULTS: We found RCT patients had higher BMI than IS and FS patients (p < 0.001, p = 0.001); more tender intermuscular septum points and night pain than IS patients (p = 0.001, p = 0.003) and more extensor group proximal tendon points than IS and FS patients (p < 0.001, p = 0.001). "No tenderness" group had lesser resting pain than distal group (p < 0.001) and lesser activity and night pain than middle-proximal, middle-distal, and distal groups (all ps < 0.002). Distal group had higher night pain than middle-proximal group (p = 0.003). Morbidly obese patients had higher night pain than normal and overweight patients (p = 0.003 and p = 0.009). CONCLUSIONS: Tender point distribution varies depending on the pathology with biceps brachii being the most common. RCT patients had higher night pain related to more distal tender points. Patients with higher night pain had increased tenderness in septum intermuscular and extensor muscles' proximal tendons.

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.

Effect of taping on scapular kinematics of patients with facioscapulohumeral muscular dystrophy.

The aim of this study is to investigate the effects of scapular taping on scapular kinematics by three-dimensional electromagnetic system during shoulder elevation in facioscapulohumeral muscular dystrophy patients. A total of 11 patients with facioscapulohumeral muscular dystrophy were included in the study. Scapular anterior-posterior tilt, upward-downward rotation, and internal-external rotations were evaluated using the three-dimensional electromagnetic system during the elevation of the upper limbs in the scapular plane before and after kinesio taping. For maximum humerothoracic elevation, there were no differences between the patients before and after taping on both dominant (p = 0.72) and non-dominant sides (p = 0.64). For scapular internal rotation, upward rotation, and posterior tilt, there were no differences between patients before and after taping during humerothoracic elevation on both dominant and non-dominant sides (p > 0.05). These results showed us that the excessive and abnormal movements of the scapula observed during the humeral elevation in facioscapulohumeral muscular dystrophy patients cannot be supported with flexible methods like kinesio taping. Therefore, we recommend to evaluate the scapula position by applying flexible and rigid taping to the patients who can reach over 90o in humerothoracic elevation in future studies.

Which method for frozen shoulder mobilization: manual posterior capsule stretching or scapular mobilization?

OBJECTIVES: This study aimed to compare the superiority of scapular mobilization, manual capsule stretching, and the combination of these two techniques in the treatment of frozen shoulder patients to evaluate the acute effects of these techniques on shoulder movements. METHODS: This study designed to a single-blinded, randomized, and pre-post assessment study. This study was included 54 patients diagnosed with stage 3 frozen shoulder. Group 1 (n=27) received scapular mobilization, and Group 2 (n=27) received manual posterior capsule stretching. After the patients were assessed, the interventions were re-applied with a crossover design to obtain results for the combined application (n=54). The range of motion, active total elevation, active internal rotation, and posterior capsule tensions of the shoulder joint were recorded before and immediately after mobilization. RESULTS: Statistical analysis showed an increase in all range of motion values (p<0.05), except for shoulder internal rotation (p>0.05), without significant difference among the groups (p>0.05). The posterior capsule flexibility did not change in any group (p>0.05). CONCLUSIONS: Scapular mobilization and manual posterior capsule interventions were effective in improving the acute joint range of motion in frozen shoulder patients.

A three-dimensional scapular motion analysis in patients with arthroscopic anterior capsulolabral repair of the shoulder: The effect of scapular stabilization taping.

BACKGROUND: The aim of this study was to investigate the scapular kinematics during dynamic humeral movements in patients with arthroscopic anterior capsulolabral repair of the shoulder along with the potential biomechanical corrective effects of scapular stabilization taping. METHODS: Twenty patients with unilateral traumatic anterior shoulder instability and arthroscopic anterior capsulolabral repair participated in the study. Dynamic shoulder kinematics were assessed during the scapular plane shoulder elevation for both the operated and non operated shoulders and also under two conditions: no-taping and taping. Statistical analysis to compare sides and conditions was performed with analysis of variance models. RESULTS: The scapula was more internally rotated position in operated shoulders than in non operated shoulders. Furthermore, the scapula was less internally rotated and more downwardly rotated at 120° of elevation in the taping condition. CONCLUSIONS: Operated shoulders demonstrated kinematics alterations when compared to non operated shoulders underwent arthroscopic anterior capsulolabral repair. Additionally, changes in the scapular orientation with the taping was very small but followed a pattern, which would be suggested to be an orientation that potentially produce more scapular stability and to increase stress on the inferior glenohumeral ligament.

"Ballistic Six" Upper-Extremity Plyometric Training for the Pediatric Volleyball Players.

Turgut, E, Cinar-Medeni, O, Colakoglu, FF, and Baltaci, G. "Ballistic Six" upper-extremity plyometric training for the pediatric volleyball players. J Strength Cond Res 33(5): 1305-1310, 2019-The Ballistic Six exercise program includes commonly used upper-body exercises, and the program is recommended for overhead throwing athletes. The purpose of the current study was to investigate the effects of a 12-week the Ballistic Six upper-extremity plyometric training program on upper-body explosive power, endurance, and reaction time in pediatric overhead athletes. Twenty-eight female pediatric volleyball players participated in the study. The participants were randomly divided into 2 study groups: an intervention group (upper-extremity plyometric training in addition to the volleyball training; n = 14) and a control group (the volleyball training only; n = 14). All the participants were assessed before and after a 12-week training program for upper-body power, strength and endurance, and reaction time. Statistical comparison was performed using an analysis of variance test. Comparisons showed that after a 12-week training program, the Ballistic Six upper-body plyometric training program resulted in more improvements in an overhead medicine ball throwing distance and a push-up performance, as well as greater improvements in the reaction time in the nonthrowing arm when compared with control training. In addition, a 12-week training program was found to be effective in achieving improvements in the reaction time in the throwing arm for both groups similarly. Compared with regular training, upper-body plyometric training resulted in additional improvements in upper-body power and strength and endurance among pediatric volleyball players. The findings of the study provide a basis for developing training protocols for pediatric volleyball players.

Neck and Scapula-Focused Exercise Training on Patients With Nonspecific Neck Pain: A Randomized Controlled Trial.

OBJECTIVES: The purpose of this study was to investigate the effects of additional 6-week scapular stabilization training in patients with nonspecific neck pain (NNP). MATERIALS AND METHODS: A total of 30 patients with NNP were randomly allocated to the study. Fifteen participants in the intervention group received neck-focused exercise and scapular stabilization training, whereas 15 participants in the control group received neck-focused exercise training. All groups were evaluated at baseline and after 6 weeks of rehabilitation. The pain intensity on the neck was measured with the visual analog scale (VAS). The self-reported disability status was measured with the neck disability index (NDI). Three-dimensional scapular kinematics were recorded during dynamic shoulder elevation trials using an electromagnetic tracking device, and data were further analyzed at 30°, 60°, 90°, and 120° of humerothoracic elevations. RESULTS: Comparisons revealed that, regardless of the received treatment, after 6 weeks of training both groups showed significant improvements in VAS (P < .001) and NDI (P < .001) scores. Both VAS and NDI outcomes have a large effect size (r = .618 and r = .619, respectively). For scapular kinematics, there were no group differences, especially for scapular upward-downward rotation and anterior-posterior tilt (P > .05). However, in the intervention group, the scapula was more externally rotated at 120° humerothoracic elevation (P = .04). CONCLUSION: Findings of this study showed that both manual therapy and active interventions, including neck-focused exercise and scapular stabilization training, are effective in decreasing pain and disability level in patients with NNP. More comprehensive studies with longer follow-up durations are needed to better understand the potential effects of scapular stabilization training in patients with NNP.

Stretching Exercises for Subacromial Impingement Syndrome: Effects of 6-Week Program on Shoulder Tightness, Pain, and Disability Status.

CONTEXT: Increasing soft tissue flexibility and joint mobility is one of the important aims of studies to treat subacromial impingement syndrome (SIS). OBJECTIVE: The aim of this study was to investigate the effects of a stretching program on posterior capsule tightness, pectoralis minor tightness, pain severity, and disability status in SIS. DESIGN: Single-group pretest posttest design. SETTING: University outpatient clinic. PARTICIPANTS: 18 participants diagnosed with SIS (34.8±9.4 y, symptoms duration 5.8±4.9 months) were included in the study. INTERVENTION: The 6-week self-stretching program for pectoralis minor, posterior capsule, levator scapula, and latissimus dorsi was performed. MAIN OUTCOME MEASURES: Posterior capsule tightness, pectoralis minor tightness, pain severity (visual analog scale), and self-reported shoulder-related pain and disability status (Shoulder Pain and Disability Index) were used to assess changes in flexibility and symptoms. RESULTS: Comparisons showed that there was significantly less posterior capsule and pectoralis minor tightness, less pain severity on activity and at night, and a lower disability score reported after the 6-week stretching program (P < 0.05). There was no statistically significant difference in pain severity at rest after the 6-week stretching program (P > 0.05). CONCLUSIONS: The findings of the study showed that flexibility, pain severity, and disability gains can be achieved with a 6-week stretching exercise training for participants with SIS. Therefore, shoulder girdle stretching exercises should be recommended early in shoulder rehabilitation program.

Effects of Scapular Stabilization Exercise Training on Scapular Kinematics, Disability, and Pain in Subacromial Impingement: A Randomized Controlled Trial.

OBJECTIVE: To investigate the effects of 2 different exercise programs on 3-dimensional scapular kinematics, disability, and pain in participants with subacromial impingement syndrome (SIS). DESIGN: Randomized controlled trial. SETTING: Outpatient clinic and research laboratory. PARTICIPANTS: Participants who were diagnosed with SIS and who also exhibited scapular dyskinesis (N=30). INTERVENTIONS: The participants were randomized in 2 different exercise groups: (1) shoulder girdle stretching and strengthening with additional scapular stabilization exercises based on a kinetic chain approach (intervention group), and (2) shoulder girdle stretching and strengthening exercises only (control group). MAIN OUTCOME MEASURES: Three-dimensional scapular kinematics, self-reported shoulder pain, and disability were evaluated at baseline, after 6 weeks of training, and after 12 weeks of training. RESULTS: Significant differences were observed between the control and intervention groups in external rotation and posterior tilt after 6 weeks of training and in external rotation, posterior tilt, and upward rotation after 12 weeks of training. All groups showed improvement in self-reported pain and disability scores; however, there were no significant differences between the groups. CONCLUSIONS: Progressive exercise training independent from specific scapular stabilization exercises provides decreased disability and pain severity in impingement syndrome.

Translation and cross-cultural adaptation of the anterior cruciate ligament-return to sport after injury (ACL-RSI) scale into Turkish.

PURPOSE: To translate and culturally adapt the anterior cruciate ligament-return to sport after injury (ACL-RSI) scale into Turkish (ACL-RSI-Tr) and examine and evaluate the psychometric properties of the Turkish version in individuals who have undergone anterior cruciate ligament (ACL) reconstruction. METHODS: The ACL-RSI was forward- and back-translated, culturally adapted and validated on ninety-three Turkish individuals who had undergone ACL reconstruction (5 females, 88 males; age 28.7 ± 8.6 years; body mass 80.1 ± 13.9 kg; height 178.8 ± 6.9 cm; body mass index 25.0 ± 3.7 kg/m2). All patients completed the translated ACL-RSI, Tampa Scale of Kinesiophobia (TSK), Knee injury and Osteoarthritis Outcome Score (KOOS) and International Knee Documentary Committee (IKDC) and Lysholm questionnaires. We then analysed the internal consistency, reliability and validity of the newly formed ACL-RSI-Tr scale. RESULTS: The ACL-RSI-Tr showed good internal consistency (Cronbach's alpha 0.86) and test-retest reliability (ICC 0.92) and was significantly correlated with the KOOS 'quality of life' (r = 0.58, p < 0.002), 'symptoms and stiffness' (r = 0.35, p = 0.001), 'pain' (r = 0.49, p < 0.001), 'sports' (r = 0.44, p < 0.001) and 'daily life' (r = 0.42, p < 0.001) subscales. The ACL-RSI-Tr also correlated significantly with the TSK (r = - 0.45, p < 0.001), Lysholm (r = 0.45, p < 0.001) and IKDC (r = 0.44, p < 0.001) scores. CONCLUSIONS: The Turkish version of the ACL-RSI scale was valid, discriminant, consistent and reliable in patients who had undergone ACL reconstruction. This score could be useful to evaluate the effect of psychological factors on return to sport following ACL surgery. LEVEL OF EVIDENCE: Diagnostic study, Level I.

Repositioning the scapula with taping following distal radius fracture: Kinematic analysis using 3-dimensional motion system.

STUDY DESIGN: Cross-sectional and controlled laboratory study using pretest-posttest design. INTRODUCTION: Patients with distal radius fracture (DRfx) report proximal segment problems. Taping is commonly recommended because it provides improved posture and function. PURPOSE OF THE STUDY: This study aimed to investigate the 3-dimensional scapular kinematics and the effect of taping on the kinematics in participants with DRfx. METHODS: Twenty participants with a unilateral history of DRfx and 20 healthy controls participated. Scapular kinematics was assessed using an electromagnetic system. Three separate strips of elastic taping were applied for participants with DRfx over the arm, scapula, and middle and lower trapezius muscles through the paravertebral muscles. Afterward, the scapular kinematics was reassessed in taped condition. RESULTS: When participants with DRfx and healthy controls compared, the scapula was more downwardly rotated at 120° of humerothoracic elevation (mean difference [MD], 9.06°) and at 120° (MD, 9.04°), 90° (MD, 5.6°) of humerothoracic lowering, more upwardly rotated at 30° of humerothoracic lowering (MD, 5.1°). Taping showed a significant effect on kinematics; specifically, the scapula was more externally rotated (38.9° untaped vs 31.1° taped) and posteriorly tilted (-9.2° untaped vs -4.8° taped) during humerothoracic elevation and lowering for participants with DRfx. DISCUSSION: Participants with DRfx showed different scapular kinematics and taping resulted in changes on tested kinematic parameters during humeral movements. Differences in scapular motion during elevation with taping showed a specific pattern. CONCLUSIONS: Overall, taping maintained a position likely to produce optimal rotator cuff function during early rehabilitation of patients with DRfx. LEVEL OF EVIDENCE: N/A.

Validity and Reliability of Visual Analog Scale Foot and Ankle: The Turkish Version.

The present study tested the reliability and validity of the Turkish version of the visual analog scale foot and ankle (VAS-FA) among healthy subjects and patients with foot problems. A total of 128 participants, 65 healthy subjects and 63 patients with foot problems, were evaluated. The VAS-FA was translated into Turkish and administered to the 128 subjects on 2 separate occasions with a 5-day interval. The test-retest reliability and internal consistency were assessed with the intraclass correlation coefficient and Cronbach's α. The validity was assessed using the correlations with Turkish versions of the Foot Function Index, the Foot and Ankle Outcome Score, and the Short-Form 36-item Health Survey. A statistically significant difference was found between the healthy group and the patient group in the overall score and subscale scores of the VAS-FA (p < .001). The internal consistency of the VAS-FA was very good, and the test-retest reliability was excellent. Adequate to good correlations were found between the overall VAS-FA score and the Foot Function Index, Foot and Ankle Outcome Score, and Short-Form 36-item Health Survey scores in the healthy and patient groups both. The Turkish version of the VAS-FA is sensitive enough to distinguish foot and ankle-specific pathologic conditions from asymptomatic conditions. The Turkish version of the VAS-FA is a reliable and valid method and can be used for foot-related problems.
