PERİFERAL VESTİBÜLER HİPOFONKSİYONDA VERTİGO, DİZZİNESS VE DENGE BOZUKLUĞU İLE FİZİKSEL AKTİVİTE, EGZERSİZ KAPASİTESİ, GÜNLÜK YAŞAM AKTİVİTELERİ VE YAŞAM KALİTESİ ARASINDAKİ İLİŞKİ

Öz

Amaç: Periferik vestibüler hipofonksiyon’da (PVH) vertigo (V), dizziness (D) ve denge bozukluğu çeşitli fonksiyonel limitasyonlara ve inaktiviteye neden olur. Bu çalışmanın amacı, PVH’li hastalarda V, D, denge bozukluğu, fiziksel aktivite düzeyi, fonksiyonel egzersiz kapasitesi, günlük yaşam aktiviteleri (GYA) ve yaşam kalitesi (YK) arasındaki ilişkiyi araştırmaktı. Yöntem: Otuz dokuz PVH hastası ve PVH hastası olmayan 32 birey çalışmaya dahil edildi. V/D şiddeti ve sıklığı Vizüel Analog Skalası (VAS) ve denge Modifiye Kliniğine Uyarlanmış Denge-Duyusal Etkileşim Testi (M-CTSIB) ve Aktiviteye Spesifik Denge Güvenlik Ölçeği (ABC) ile değerlendirildi. Fiziksel aktivite düzeyi Uluslararası Fiziksel Aktivite Anketi (UFAA) ve fonksiyonel egzersiz kapasitesi altı dakika yürüme testi (6DKYT) ile ölçüldü. GYA Vestibüler Bozukluklarda Günlük Yaşam Aktiviteleri Ölçeği (VGYA) ve YK Baş Dönmesi Engellilik Envanteri (BEE) ile değerlendirildi. Sonuçlar: PVH'li hastalarda M-CTSIB, ABC, UFAA, 6DYT, VGYA ve BEE skorlarının kontrol grubuna göre daha düşük olduğu görüldü (p<0,05). V şiddeti ve frekansı UFAA (r=-0,602, r=-0,321), VGYA (r=0,626, r=0,492) ve BEE (r=0,640, r=0,578) ile ilişkili bulundu (p<0,05). D şiddet ve frekansı UFAA (r=-0,493 and r=-0,487), VGYA (r=0,565 and r=0,408) ve BEE (r=0,627 and r=0,566) ile korele idi (p<0,05). V ve D şiddeti 6DYT ile ilişkili idi (sırasıyla; r=-0,339 ve r=-0,336, p<0,05). Somatosensör ve görsel duyular azaldığı zaman; denge 6DYT (r=-0,412); VGYA (r=0,545) ve BEE (r=0,422) ile ilişkili bulundu (p<0,05). Tartışma: PVH'de V, D ve denge bozukluğu fiziksel aktivite düzeyi, fonksiyonel egzersiz kapasitesi, GYA ve YK ile ilişkilidir. Vestibüler rehabilitasyon programlarının, fiziksel aktivite ve fonksiyonel egzersiz kapasitesinin iyileştirilmesine etkisini araştıran ileri çalışmalara ihtiyaç bulunmaktadır.

RELATION OF VERTIGO, DIZZINESS, AND IMBALANCE WITH PHYSICAL ACTIVITY, EXERCISE CAPACITY, ACTIVITIES OF DAILY LIVING, AND QUALITY OF LIFE IN PERIPHERAL VESTIBULAR HYPOFUNCTION

Abstract

Purpose: Vertigo (V), dizziness (D), and imbalance cause functional limitation and participation in peripheral vestibular hypofunction (PVH). The aim was to investigate the relation of V, D, imbalance, with physical activity, exercise capacity, activities of daily living (ADL), and quality of life (QoL) in patients with PVH. Methods: Thirty-nine subjects with and 32 without PVH were included. The V and D severity and frequency using Visual Analogue Scale (VAS), balance using Modified Clinical Test of Sensory Interaction and Balance (M-CTSIB), and Activity Specific Balance Confidence Scale (ABC) were assessed. Physical activity using the International Physical Activity Questionnaire (IPAQ) and functional exercise capacity using the 6-minute walk test (6MWT) were evaluated. ADL using the Vestibular Disorders ADL Scale (VADL) and QoL using the Dizziness Handicap Inventory (DHI) were determined. Results: M-CTSIB, ABC, IPAQ, 6MWT, VADL, and DHI were lower in patients with PVH as compared to the control group (p<0.05). V-severity and -frequency were related to IPAQ (r=-0.602 and r=-0.321), VADL (r=0.626 and r=0.492), and DHI (r=0.640 and r=0.578, respectively, p<0.05). Both D-severity and -frequency was correlated with IPAQ (r=-0.493 and r=-0.487), VADL (r=0.565 and r=0.408), and DHI (r=0.627 and r=0.566, respectively, p<0.05). V- and D-severity was associated with 6MWT (r=-0.339 and r=-0.336, respectively, p<0.05). When somatosensory and visual sensations decreased, the balance was correlated with 6MWT (r=-0.412), VADL (r=0.545), and DHI (r=0.422, p<0.05). Conclusion: The V, D, and imbalance are associated with physical activity level, functional exercise capacity, ADL, and QoL in PVH. Further study is needed to investigate the effects of vestibular rehabilitation programs to improve physical activity and functional exercise capacity.
