Exercise With Dual Task in Knee Osteoarthritis

Neuromuscular and Perceptual Responses, Pain Intensity and Performance During Resistance Exercise With a Self-regulated Dual-task in Patients With Severe Knee Osteoarthritis

The purpose of this study is to evaluate the neuromuscular and perceptual responses, pain intensity and performance in patients with severe knee osteoarthritis in a preoperative setting with low-load resistance training with a self-regulated mathematical dual-task.

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.
