Are there any change in pain, physical function, mental well-being, the risk of fall, health belief and self-efficacy and quality of life after the intervention is carried out at week 5? 2. Are there any significance difference in pain, physical function, mental well-being, the risk of fall, health belief and self-efficacy and quality of life between the experimental and control group at baseline and week 5. 3. What are the factors related to the adherence to programme within 5 weeks it is delivered. 4. What are the factors that facilitates or inhibits the implementation process of the programme Selected clusters will be randomized into either experimental or control group. The experimental group will receive the self-management and exercise programme, which will be delivered using mobile messaging application, twice per week for five weeks.
