Brief Summary
Background: Clinical recommendations suggest exercises as the core treatment for knee osteoarthritis (OA) patients. However, the biomechanical modification following exercise therapy and its influence on pain remains unclear. The purpose of the study to compare the effectiveness of two different exercise programs, open kinetic chain (CKC) and closed kinetic chain (CKC) strengthening exercises, on pain and lower limb biomechanics for people more than 50 years old with painful mild grade knee OA. Method: 66 individuals with mild knee OA, with knee pain in the previous one week, aged 50 years and above, and who have body mass index (BMI) between 18.9kg/m2 - 29.9 kg/m2 in Kelantan, Malaysia will be recruited in this study. Participants will be randomly allocated into three different groups, either OKC, CKC, or control groups. Participants in OKC and CKC groups will perform the exercises at their home three times per week for eight weeks. The control group will receive only the patient's clinical education about clinical manifestations, risk factors, diagnosis, treatment, and nursing care for knee OA and printed materials will be given. The outcome will be measured before and after the intervention. Primary outcomes are self-reported pain, disability, and quality of life scores. Secondary outcomes include lower limb biomechanics during gait and sit-to-stand, and knee isokinetic strength. Discussion: This study will compare the efficacy of two different home-based exercise intervention programs for people with mild grade knee OA. Findings will provide valuable information for creating an effective exercise program that could slow down the progression of OA.

Outcome Measures
Primary Outcomes (3)
Change from baseline of pain intensity score at post-intervention
pain intensity will be assessed using a visual analogue scale. It consists of a bidirectional 10-cm straight line, where 0 cm is "no pain" and 10 cm is "worst imaginable pain," located at either end of the line. Patients will be instructed to draw a vertical mark on the line indicating their pain level.
8 weeks
Change from baseline of disability score at post-intervention
Western Ontario and McMaster Universities Arthritis Index consists of a number of questions designed to assess the clinical severity of the disease (5 questions for pain, 2 questions for stiffness and 17 questions for physical function). It includes 24 questions, each question scored using a five-point scale (0-4) with higher scores representing greater levels of pain, stiffness and severity of the disease. The overall score (index) is determined by summing the scores across the three dimensions and the score ranges between 0-96 (derived from a 0-4 Likert scale).
8 weeks
Change from baseline of quality of life score at post-intervention
The Osteoarthritis Knee and Hip Quality of Life in Malay Version consists of 43 items divided into five dimensions: physical activity, mental health, pain, social support, and social functioning Each item in the five dimensions is measured on a numerical rating scale from 0 to 10. Each item is scored on a scale from 0 to 10, and the normalized scores were obtained by computing the sum of item scores for each domain and calculated to a scale from 0 (worst) to 100 (best) possible quality of life.

Study Arms (3)
Open kinetic chain exercise
EXPERIMENTALIn the OKC exercise group, participants will be taught by a physiotherapist about open kinetic chain exercises. Then, they will do the exercises at their home for eight weeks, with three session per week. The physiotherapist will contact the participants to monitor their adherence to the intervention. A diary is also provided to monitor their progress, pain level and any adverse events related to the intervention.
Closed kinetic chain exercise
EXPERIMENTALIn the OKC exercise group, participants will be taught by a physiotherapist about open kinetic chain exercises. Then, they will do the exercises at their home for eight weeks, with three session per week. The physiotherapist will contact the participants to monitor their adherence to the intervention. A diary is also provided to monitor their progress, pain level and any adverse events related to the intervention.
Control
NO INTERVENTIONThe untreated control group will receive patient's usual care of local government hospital which includes information about clinical manifestations, risk factors, diagnosis, treatment and nursing care for knee OA. Control group did not receive any home exercises guidance.
Interventions
CKC: exercise with joints fixed on the ground OKC: exercise with joints not fixed on the ground
