Research participants diagnosed with knee osteoarthritis will be randomized through a draw using sealed opaque envelopes indicating two groups: 1. therapeutic exercises, 2. therapeutic exercises + chronic pain neuroscience education program. The primary outcome will be functional performance using a patient-reported measure, the Knee Injury and Osteoarthritis Outcome Score (KOOS).
The selected secondary outcomes will be pain intensity by the numerical pain scale (END), physical function reported by the patient by the patient-specific functional scale (EFEP), Pain self-efficacy questionnaire (PSEQ), functional mobility by the timed up and test (TUG), general effect perceived through the global perception scale (EPG), muscle strength through Maximum Voluntary Isometric Contraction (MVIC) and functionality and disability through the World Health Organization Disability Assessment Schedule (WHODAS).
A clinical diagnosis of knee osteoarthritis (knee pain for > 3 months
Morning stiffness <30 minutes
Crepitus
Bone tenderness, and absence of palpable heat and/or diagnosis established radiographically (determined by Kellgren and Lawrence grade 1 to 3 on a scale 1 up to 4)
Hip OA
severe osteoporosis
Fibromyalgia
Medical history of tumors or cancer
Parallel
Therapeutic exercises
Other interventionThe therapeutic exercise program will include warm-up, resistance, neuromuscular, mobility, and balance exercises. Over ten weeks, two sessions of the therapeutic exercise program will be carried out individually, lasting approximately 60 minutes each-a total of 20 therapeutic exercise sessions. Therapeutic exercise sessions will be carried out at least 24 hours between sessions. Therapeutic exercises will be performed in up to three sets of 8-12 repetitions or 30-60 seconds each, with rest intervals of 90 seconds between sets.
Therapeutic exercises + pain neuroscience education program
Other interventionIn addition to the therapeutic exercise protocol previously reported in the control group, research participants allocated to the experimental group will undergo an education program in the neurosciences of chronic pain carried out one day a week between the two therapeutic exercise sessions lasting ten weeks. The chronic pain neuroscience education program will be based on three domains. Making sense of pain, Exposure with control, and Lifestyle changes also urge modifications aimed at improving sleep, stress, and anxiety.
Functional disability
Knee Injury and Osteoarthritis Outcome Score (KOOS). It aims to evaluate the domains of pain, symptoms, activities of daily living, function related to recreation and sports, and quality of life related to the knee. Totaling 42 items, each item must be answered using a Likert scale that ranges from 0 (best score) to 4 (worst score), and the score for each subscale ranges from 0 (worst score) to 100 (best score).
Numerical Pain Scale
The Numerical rating pain scale, a simple, easily administered scale evaluates the perceived intensity of pain, using an 11-point scale from 0, representing 'no pain', to 10, which is the 'worst possible pain'.
Functional self-perception
Pain self-efficacy questionnaire, structured into 10 items where each item is evaluated by selecting a number on a 7-point numerical scale (scores from 0 to 6), where 0 means "not at all confident" and 6 means "completely confident". The items cover different functions, from work, social activities, domestic tasks and coping with pain without medication. A total score is calculated from the sum of the scores for each of the 10 items, producing a total score that ranges from 0 to 60. Higher scores reflect stronger self-efficacy beliefs.
Self-perceived functionality
Patient Specific Functional Scale. An easy-to-apply self-report instrument, validated for measuring disability related to specific tasks identified by the individual. The scale is made up of 11 (eleven) numbers, graduated from 0 (zero) to 10 (ten), where 0 (zero) represents inability to perform the activity and ten (ten) the ability to perform the activity at the level prior to the current condition.
Maximum voluntary isometric contraction
manual dynamometer portable (Lafayette Manual Muscle System, Modelo 01165, Lafayette Instrument Company, Lafayette, IN). Four 5-second readings will be taken during maximal voluntary isometric contraction (MVIC) with a 30-second rest period between contractions. The first CIVM will familiarize the volunteer with carrying out the task. A new set of readings will be taken if a volunteer can perform three contractions with at least 10% variability. Strong and constant verbal stimuli will be used throughout the test. Always with the research participants' hands positioned crossed on the chest. Thus, bilateral assessments of the muscles, quadriceps, and gluteus medius will be carried out. The order of CIVM readings will be randomized to avoid collection bias. The research participant will remain in lateral decubitus with a pillow positioned between the legs, with the limb to be tested superiorly in a neutral position.
