Patients' views toward knee osteoarthritis exercise therapy and factors influencing adherence - a survey in China

Objectives: To understand the views toward exercise therapy for knee osteoarthritis (KOA) in China and to analyze factors affecting treatment adherence. Methods: A survey-based study, which included multiple choice and open-ended questions on knee OA exercise therapy was conducted in a Chinese population. The content included the respondents' attitudes and beliefs, willingness to receive treatment, and reasons why they could or could not adhere to the treatment. We used Chi-squared tests to compare cognitive differences between the patients and non-patient groups. Results: A total of 1,069 people responded to the questionnaire, and the response rate was 81.8%. A total of 93.6% of the patients thought that they could adhere to the exercise treatment if they received professional advice and prescriptions. The following questionnaire items achieved consensus: 'Increasing the strength of the muscles around the knee stops the knee pain from getting worse,' It is the person's own responsibility to continue doing their exercise program,' How helpful the exercise program will be determines how well a person sticks to it,' Health professionals should educate patients with knee pain about how to change their lifestyle for the better,' and 'Exercise for knee pain is most helpful when it is designed for each person, to suit their own particular needs.' Patient adherence was affected by multiple factors, and some negative factors included 'forgetfulness,"getting joint symptoms improved after therapy,' professional guidance, subsequent monitoring and supervision,"willing to enhance overall health and quality of life,' having no time,' occupational factors,' 'considering that the pain would worsen while/after exercise,' and 'family factors.' Conclusions: A general Chinese population accepted exercise therapy for treating KOA in our survey. Education is necessary because patients were uncertain and had misunderstandings regarding the potential benefits of exercise therapy. Some factors related to treatment adherence were also analyzed.
