Relationship between muscle performance and perceived fatigue in individuals with knee osteoarthritis. Malaysian Journal of Medicine and Health Sciences, 17 (SUPP3). pp. 1-8. ISSN 2636-9346 (2021)
Abstract
Introduction: Knee osteoarthritis (KOA) is a painful degenerative joint disease that may limit movement. This study aimed to compare muscle performance (strength of handgrip strength, lower limb muscles, and lower limb function) and perceived fatigue between individuals with and without KOA, and determined the relationship between muscle performance and perceived fatigue in individuals with KOA.
Methods: This cross-sectional study recruited 33 female patients (Age=54.76±5.54 years) diagnosed with KOA and 33 healthy participants (Age=53.30±5.55 years). Handgrip strength was assessed by using a Hand Dynamometer. The strength of the lower limb muscles (Hip extensors, flexors, abductors, and adductors; knee extensors and flexors) was assessed by the push and pull dynamometer. Lower limb functional strength was assessed by the Five Times Sit to Stand Test. The Fatigue Severity Scale was used to measure the perception of fatigue related to daily function. Data were analyzed using an independent t-test and Pearson’s correlation.
Results: Individuals with KOA were significantly higher in handgrip strength and perceived fatigue, and poorer in lower limb functional strength (All p<0.05). There were no significant differences in all measures of lower limb muscles between individuals with and without KOA (All p>0.05). Hip flexors, knee extensors, and knee flexors were significant correlated with perceived fatigue (All p<0.05) in individuals with KOA.
Conclusion: Findings of this study suggest that individuals with KOA may have lower functional strength and higher perceived fatigue. The hip flexors, knee extensors, and knee flexors may be associated with a higher level of perceived fatigue among individuals with KOA.
