Investigating the effect of an Orem-based self-care educative supportive nursing system on the joint function of patients with knee osteoarthritis

Abstract

BACKGROUND: Osteoarthritis is the most common form of arthritis. It is a common progressive joint disease characterized by chronic pain and functional disability, which disturbs functional movements, body balance, and quality of life in patients with knee osteoarthritis. This study investigates the effect of an Orem-based self-care educative supportive nursing system on the joint function of patients with knee osteoarthritis. MATERIALS AND METHODS: This semi-experimental paper studies 130 patients with knee osteoarthritis. The patients are selected using convenience sampling and randomly assigned to intervention and control groups equally. The K00S questionnaire was used to collect patients’ demographic information and other information relating to their knees’ function. We carried out interventions for six weeks, with a session of 45 to 60 minutes each week. Data were collected before the intervention and three months after the intervention. SPSS 21.0 and descriptive and inferential statistics were used to analyze the collected data at the significance level of 0.05. RESULTS: The results show significant differences between the two groups in terms of joint symptoms (P = 0.001), pain (P = 0.001), daily activities (P = 0.001), sports and recreational activities (P = 0.001), and quality of life (P = 0.02). In other words, there was a significant difference in the average subscale scores of activities in all five dimensions between the intervention and control groups (P < 0.05). CONCLUSION: Orem’s self-care model has a positive and significant effect on the functional movement of patients with knee osteoarthritis and improves their joint function.
