Effect of Structured Exercise in Patients With Knee Osteoarthritis

Recruiting now · Not applicable

Conditions studied: Osteoarthritis, Knee, Physical Inactivity

In brief

The aim of this randomized controlled trial is to evaluate the effect of Nordic walking and inspiratory muscle training (IMT) on cardiopulmonary function in patients with knee osteoarthritis (OA). Mild-to-moderate knee OA patients are randomly allocated into Experimental group (Nordic walking plus routine management) or Control group (Routine management). While End-stage knee OA patients are randomly allocated into Experimental group (IMT plus pre-operative rehabilitation exercise) or Control group (Pre-operative rehabilitation exercise). Participants are invited to undergo two assessments, including baseline assessment, post-intervention assessment. Researchers will compare two groups to see if the cardiopulmonary function can be improved after intervention.

Who can join

You may qualify if…

• pain on the most days in one or both knees in the past month;
• difficulty with at least one of daily living activities measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scale;
• radiographic evidence of knee OA in the tibial-femoral compartment (Kellgren and Lawrence grade, K/L ≥1, K/L 1-3 regarded as mild-to-moderate knee OA, others waiting for knee arthroplasty regarded as end-stage knee OA);
• with normal or corrected visual and auditory function and walking unaided;
• primary knee OA for more than 6 months, be stable on medication for at least 3 weeks.

You may not qualify if…

• knee surgery priorly;
• have steroid injection in previous three weeks;
• have inflammatory arthritis (e.g., rheumatoid); or unstable angina, or myocardial infarction, or cardiac surgery; or stroke; or treatment with steroids, hormones, or cancer chemotherapy; or pulmonary diseases (force vital capacity<80% of predicted and/or forced expiratory volume at first second<70% of predicted); or a history of exercise-induced asthma;
• unable to understand the procedure and potential risks of the study;
• medically unstable that indicate unsafe to participate in exercise test
