Contribution of Leg Muscle Strength to Balance in Multiple Sclerosis Patients

Öz

This study aims to compare lower extremity muscle strength, and balance in people with Multiple Sclerosis with mild disability to healthy controls, and determine the relationships between lower extremity muscle strength, and balance. In this study, 34 people with Multiple Sclerosis with mild disability (Expanded Disabilitiy Status Scale: 1.40±0.56) and 16 healthy controls were enrolled. The muscle strength of lower extremity muscles was evaluated with a hand-held dynamometer. The balance of people with Multiple Sclerosis with mild disability was assessed with Biodex Balance System-BioSwayTM. The balance performance and hip abductor, hip adductor, knee flexor, and weakest ankle dorsiflexor muscle strength were lower in people with Multiple Sclerosis with mild disability than in the healthy controls. The results of correlation and multiple regression analysis balance in people with Multiple Sclerosis with mild disability were related to different lower extremity muscle strengths. According to the results, exercise training that aims to improve balance should include these muscles in people with Multiple Sclerosis with mild disability.

Multipl Skleroz Hastalarında Alt Ekstremite Kas Kuvvetinin Denge Parametrelerine Katkısı

Öz

Bu çalışmanın amacı, hafif engelli Multipl Sklerozlu bireylerde alt ekstremite kas gücü ve dengeyi sağlıklı kontrollerle karşılaştırmak ve alt ekstremite kas gücü ile denge arasındaki ilişkileri belirlemektir. Bu çalışmaya, hafif engelli (Genişletilmiş Engellilik Durum Ölçeği: 1.40±0.56) 34 Multipl Sklerozlu birey ve 16 sağlıklı control dahil edildi. Alt ekstremite kaslarının kas gücü manuel dinamometre ile değerlendirildi. Hafif engelli Multipl Sklerozlu bireylerin dengesi Biodex Denge Sistemi-Bio Sway TM ile değerlendirildi. Hafif engelli Multipl Sklerozlu bireylerde denge performansı ve kalça abdüktör, kalça adduktör, dizfleksör ve en zayıf ayak bileği dorsifleksör kas gücü, sağlıklı kontrollere gore daha düşüktü. Korelasyon ve çoklu regresyon analizi sonuçları hafif engelli Multipl Sklerozlu bireylerde farklı alt ekstremite kas güçleriyle ilişkiliydi. Sonuçlara göre, hafif engelli Multipl Sklerozlu bireylerde dengeyi geliştirmeyi amaçlayan egzersiz eğitimi bu kasları içermelidir.
