Eligibility Criteria
Inclusion Criteria
- •men and women above 55 years old.
- •diagnosed with severe knee osteoarthritis.
- •scheduled for unilateral TKA surgery in a local hospital during 2021- 2022.
Exclusion Criteria
- •pain in the contralateral limb (maximum pain, ≥80 of 100 mm on a VAS during daily activities).
- •another hip or knee joint replacement in the previous year.
- •any medical condition in which exercise was contraindicated.
- •participated in exercise programs (\>2 days/week, training at intensities of 10-15RM) in the 6 months prior to the study.
- •history of stroke, brain surgery, major depression, or any self-perceived cognitive alterations that could affect the performance of dual tasks.
Outcomes
Primary Outcomes
Self-reported pain intensity (Visual Analogue Scale (VAS) Scale 0-10)
Time Frame: Pre exercise, immediate post set, immediate post session, and 10 minutes after session.
Change from baseline to the end of the session, and the change between the treatment group and the placebo group.
HDsEMG
Time Frame: During each experimental session and during each exercise condition.
Change between baseline and exercise, and the change between the treatment group and the placebo group.
Pressure pain thresholds
Time Frame: Pre exercise, immediate post session, and 10 minutes after session.
Change from baseline to the end of the session, and the change between the treatment group and the placebo group.
Secondary Outcomes
- Tampa Scale of Kinesiophobia (TSK 11)(Pre session.)
- Chronic Pain Self-Efficacy Scale (CPSS)(Pre session.)
- Pain Catastrophizing Scale (PCS)(Pre session.)
- Heart Rate(Pre exercise, immediate post set, immediate post session, and 10 minutes after session.)
- WOMAC questionaire for patients with hip or knee osteoarthritis.(Pre session.)
- Rating of perceived exertion (RPE) based on Borg's CR10 scale(Immediate post exercise.)
