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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Regular Task | Active Comparator | Knee extensions. |
|
| Dual Task | Experimental | Knee extensions while also doing a self-regulated mathematical dual-task. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Resistance exercise | Other | Do the maximum number of repetitions of externally-resisted (50% 1RM) knee extensions. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Self-reported pain intensity (Visual Analogue Scale (VAS) Scale 0-10) | Change from baseline to the end of the session, and the change between the dual-task and the regular condition. | Pre exercise, immediate post session, and 10 minutes after session. |
| Pressure pain thresholds | Change from baseline to the end of the session, and the change between the dual-task and the regular condition. | Pre exercise, immediate post session, and 10 minutes after session. |
| HDsEMG | Change from baseline to the end of the session, and the change between the dual-task and the regular condition. | During each experimental session and during each exercise condition. |
| Performance | Maximum number of exercise repetitions performed. | During each experimental session and during each exercise condition. |
| Measure | Description | Time Frame |
|---|---|---|
| Tampa Scale of Kinesiophobia (TSK 11) | Its score range is 11-44, with higher scores reflecting worse condition. | Pre session. |
| Pain Catastrophizing Scale (PCS) | 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. |

| Pre session. |
| Chronic Pain Self-Efficacy Scale (CPSS) | 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. | Pre session. |
| WOMAC questionaire for patients with hip or knee osteoarthritis. | 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. | Pre session. |
| Heart Rate | Change from baseline to the end of the session, and the change between the dual-task and the regular condition. | Pre exercise, immediate post session, and 10 minutes after session. |
| Perceived difficulty of the dual-task. | Based on an 11-point numerical rating scale. | Immediate post exercise. |
