GRIP FORCE AND ULTRASOUND EXAMINATION OF MUSCLE ARCHITECTURE IN RHEUMATOID ARTHRITIS PATIENTS-A PILOT STUDY
Journal Title: International Journal of Medical and Clinical Research - Year 2011, Vol 2, Issue 2
Abstract
The aims of this study were to measure grip force (flexion and extension force) in patients with Rheumatoid Arthritis (RA) and compare them with healthy subjects. We also wanted to explore the possible causes of impaired finger extension force with the help of ultrasound muscle analyses. The study group comprised of 20 patients with RA and 20 healthy age-matched controls. The grip force was measured and the extensor digitorum communis muscle was examined with ultrasound. The results showed significant differences in force capacity as well as differences in structural parameters and the intra muscle movements were more pronounced in the healthy subjects than in RA patients. The results show differences in structural parameters as well as functional tests, i.e. contraction time and extension muscle force capacity, between normal and RA muscles. Ultrasound and grip force measurements are useful tools for evaluation of muscle architectures and grip force after rehabilitation.
