 This study investigated the effects of a daily living activities, DLA, model on arm dysfunction, lymphedema, and quality of life in patients who had undergone breast cancer surgery. The DLA model included physical therapy, occupational therapy, and psychological support. Patients were randomly assigned into two groups, one receiving the DLA model and the other serving as a control group. Data were collected from 60 patients at a tertiary hospital over three months. The results showed that the DLA model was effective in reducing arm dysfunction, lymphedema, and improving quality of life. Specifically, the spofia, dash, and cat scales all improved significantly in the intervention group compared to the control group. Additionally, the upper arm circumference decreased significantly in the intervention group compared to the control group. Overall, these findings suggest that the DLA model can be beneficial in reducing arm dysfunction, lymphedema, and improving quality of life in patients who have undergone breast cancer surgery.
