Only the study team can determine whether someone qualifies for participation.

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.

Treatment and study plan

Resistance Exercise

Other

Do the maximum number of repetitions of externally-resisted (50% 1RM) knee extensions.

Primary outcomes

  1. Self-reported pain intensity (Visual Analogue Scale (VAS) Scale 0-10)

    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 dual-task and the regular condition.

  2. 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 dual-task and the regular condition.

  3. HDsEMG

    Time frame: During each experimental session and during each exercise condition.

    Change from baseline to the end of the session, and the change between the dual-task and the regular condition.

  4. Performance

    Time frame: During each experimental session and during each exercise condition.

    Maximum number of exercise repetitions performed.

Secondary outcomes

  1. Tampa Scale of Kinesiophobia (TSK 11)

    Time frame: Pre session.

    Its score range is 11-44, with higher scores reflecting worse condition.

  2. Pain Catastrophizing Scale (PCS)

    Time frame: Pre session.

    People are asked to indicate the degree to which they have certain thoughts and feelings when they are experiencing pain using the 0 (not at all) to 4 (all the time) scale. A total score is yielded (ranging from 0-52), along with three subscale scores assessing rumination, magnification and helplessness, with higher scores reflecting worse condition.

  3. Chronic Pain Self-Efficacy Scale (CPSS)

    Time frame: Pre session.

    The Chronic Pain Self-Efficacy Scale (CPSS) is designed to measure chronic pain patients' perceived self-efficacy to cope with the consequences of chronic pain. The CPSS measures three domains of pain self-efficacy: pain management, physical functioning, and coping with symptoms. A total score is yielded (ranging from 220-2200), with higher scores reflecting a better condition.

  4. WOMAC questionaire for patients with hip or knee osteoarthritis.

    Time frame: Pre session.

    The WOMAC is a disease-specific self-administered questionnaire for patients with hip or knee osteoarthritis. It has a multidimensional scale made up of 24 items grouped into three dimensions: pain (5 items), stiffness (2 items) and physical function (17 items). For each item, it uses a Likert scale with five response levels, representing different degrees of intensity (none, mild, moderate, severe or extreme) that are scored from 0 to 4. The final score for the WOMAC is determined by adding the aggregate scores for pain, stiffness and function. The higher the score, the worse the patient's condition.

  5. Heart Rate

    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 dual-task and the regular condition.

  6. Perceived difficulty of the dual-task.

    Time frame: Immediate post exercise.

    Based on an 11-point numerical rating scale.
