Erişkin Kistik Fibrozisli Bireylerde Kemik Mineral Yoğunluğunun Postür, Solunum Fonksiyonları ve Fonksiyonel Egzersiz Kapasitesi Üzerine Etkisi

Abstract

In individuals with Cystic Fibrosis (CF), a decrease in bone mineral density (BMD) as a result of systemic effects is a common condition. The aim of this study was to examine postural change, trunk stabilization, pulmonary function, functional exercise capacity, body awareness and cosmetic deformity perception levels due to postural changes in adults with CF with low and normal bone mineral density. Physical and demographic characteristics and BMD measurement results were recorded. The Modified Medical Research Council Scale was used for dyspnea assessment and the Incremental Shuttle Walking Test was used for functional exercise capacity assessment. Lung function was measured using a spirometer, respiratory muscle strength was measured using a mouth pressure measuring device, respiratory muscle endurance tests at incremental threshold load and fixed threshold load were measured using a Power Breathe device. Quadriceps and handgrip muscle strength were evaluated for peripheral muscle strength. Cobb angle was measured using radiographs taken in the last 6 months and Corbin Posture Analysis was used for observational posture assessment. Body composition was assessed using a Skinfold caliper; core stabilization was assessed using Sahrmann's Core Stabilization Test; body awareness was assessed using Body Awareness Rating Questionnaire (BARQ-T); cosmetic deformity perception was assessed using Walter Reed Visual Assessment Scale, Trunk Appearance Perception Scale (TAPS) and TAPS kyphosis parameter (KyphoTAPS). The London Chest Activities of Daily Living Scale and Bouchard's Three-Day Physical Activity Record were used to assess activities of daily living and physical activity. Pain severity was recorded using the Visual Analogue Scale (VAS). A total of 45 clinically stable individuals diagnosed with CF, aged 18-45 years (24.60±5.72), 20 females and 25 males were included in the study. Adults with CF were divided into two groups as low BMD and normal BMD. Lung function, body fat percentage, BARQ-T function parameter results were found to be lower in adults with low BMD compared to adults with normal BMD (p<0.05); while activities of daily living and cosmetic deformity perception were found to be higher than those of with normal BMD (p<0.05). Dyspnea level, functional exercise capacity, respiratory muscle strength and endurance, peripheral muscle strength, posture, core stabilization and physical activity levels were similar in adults with low and normal BMD (p>0.05). It is recommended that skeletal muscle system, respiratory system, activities of daily living, cosmetic deformity perception due to postural changes and body composition are parameters that should be taken into consideration during the evaluation that these are parameters that should be taken into account for follow-up in future studies.
