Brief summary
The goal of this randomized clinical trial is to improve osteoarthritis symptoms and quality of life in older people with knee osteoarthritis from a primary care center. The main question it aims to answer is: * To participate in a Nordic walking reduces pain measured on WOMAC pain dimension? * To participate in a Nordic walking improves mobility measured on WOMAC physical activitiy dimension? Researchers will compare pain and physical activity outcomes between intervention and control arm (randomly allocated).
Detailed description
Osteoarthritis is one of the clinical circumstances that produces the most disability in terms of disability-adjusted life years (DALYs), its main localization is in the knees and hips, the most disabling joints. Ten percent of the adult Spanish population has knee osteoarthritis , which is accompanied by symptoms of pain, mechanical alterations, stiffness, and decreased functionality, constituting one of the most common causes of disability in older people.. Decreased muscle mass and strength of knee extensor-flexor muscles are associated with symptomatic progression of oseoarthritis and lower general health status.
Interventions
The intervention is a defined program of Nordic walking and strengthening exercises for 10 weeks in a regimen of two days per week (two 75-minute sessions per week). In these sessions, they did Nordic walking three 5-minute breaks, where strength and proprioception exercises of the lower extremities were performed.
OTHEREducational advise
Patients in the control arm participated in a single session to advise them on the need for self-exercise.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Western Ontario and McMaster Universities Osteoarthritis Index | From enrollment to the end of treatment at 10 weeks | The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation of Hip and Knee Osteoarthritis. It is a self-administered questionnaire consisting of 24 items divided into 3 subscales: pain (5 items), stiffness (2 items) and physical function. WOMAC is available and validated in Spanish language. Overall, the sum of the three dimensions can have a minimum of zero points and a maximum of 96 points where 0 represents the best health status and 96 the worst possible status. The higher the score, the poorer the function. |

| 36-Item Short Form Survey Instrument (SF-36) | From enrollment to the end of treatment at 10 weeks | The 36-Item Short Form Survey (SF-36) is an outcome measure instrument that is often used, well-researched, self-reported measure of physical and mental health scores. The SF-36 has eight scaled scores; the scores are weighted sums of the questions in each section. Scores range from 0 - 100 where lower scores identifies more disability and higher scores identifies less disability. The sections are vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning and mental health. |

| Measure | Time frame | Description |
|---|---|---|
| Time up and go | From enrollment to the end of treatment at 10 weeks | The test begins with the subject sitting correctly in a chair with arms, the subject's back should resting on the back of the chair. The chair should be stableand positioned such that it will not move when the subject moves from sitting to standing. On the word go the subject sou will stand up, walk to the line on the floor (3 meters from the chair), turn around and walk back to the chair and sit down. Walk at his or her regular pace. Start timing on the word go and stop timing when the subject is seated again correctly in the chair with their back resting on the back of the chair. Interpretation: \<10 seconds is normal, \<20 seconds is good mobility, can go out alone, mobile without a gait aid and \<30 seconds = problems, cannot go outside alone, requires a gait aid. |
| Sit to stand | From enrollment to the end of treatment at 10 weeks | It counts the number of times the patient comes to a full standing position in 30 seconds. Record the number of times the patient stands in 30 seconds. An average score indicates a risk for falls: adjusted by age group and gender the scores ranges from less than 14 or less than 4. |
| 6-minute walk test | From enrollment to the end of treatment at 10 weeks | The 6-minute walk test (6MWT) is an assessment to determine a person's exercise tolerance. It is a low risk test that measures how far a person can walk in 6 minutes. It may be useful for measuring the functional ability and fitness of people with certain health conditions. Evidence suggests that the minimum score for healthy adults is 400 m. Scoring less than 400 meters suggests reduced exercise capacity. |
