The goal of this randomized clinical trial is to improve osteoarthritis symptoms andquality of life in older people with knee osteoarthritis from a primary care center. Themain 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).
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.
Other: Nordic walking program
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.
Other: Educational advise
Patients in the control arm participated in a single session to advise them on the need
for self-exercise.
