Description of intervention(s) / exposure
This is a cross-sectional study. We will compare muscle function and metabolism of elderly people with osteoarthritis with muscle from elderly people without OA and young volunteers.
In addition, we will correlate muscle function and metabolism measures with gait, strength and quality of life measures in people with OA.
Each patient is observed twice and each session will take 60 minutes. In addition, people with OA will come to the laboratory for one session of 3 hours to assess their gait.

Not applicable
Comparator / control treatment
This study will compare 3 groups: elderly people with severe OA, aged and body mass index (BMI) matched asymptomatic individuals and young volunteers.
Control group
Uncontrolled

Outcomes
Primary outcome [1] 258713 0
Muscle metabolism:
- inflammatory cytokine gene and protein expressions
- genes and proteins that involved in muscular protein synthesis and degradation.
- proteins and genes involved in regulating ion transport and excitability including sudium potassium pumps.
The outcomes will be assessed from analyses of muscle samples (western blots and messenger ribonucleic acid (mRNA) expression).
Timepoint [1] 258713 0
Cross sectional
Secondary outcome [1] 264738 0
Correlation between the Primary measures and gait and strength measures. Gait measures will be assessed using Vicon. Strength will be assessed using strain gauge (load cell).
