The effectiveness of progressive muscle relaxation technique in reducing cancer-related pain among palliative care patients: A randomized controlled trial

Purpose: Cancer-related pain (CRP) is a common and distressing symptom experienced by many patients receiving palliative care. The purpose of this trial was to evaluate the effectiveness of the progressive muscle relaxation (PMR) technique in reducing CRP in patients receiving palliative care. Methods: A total of 148 patients diagnosed with cancer and receiving palliative care were randomly allocated to either an intervention or control group. The intervention group received a 4-week daily course of PMR technique, while the control group received only usual care. Data was collected using a demographic and clinical characteristics form, as well as the Brief Pain Inventory (BPI). Blind evaluations were conducted prior to the start of the intervention (T0), at the end of the 4-week PMR intervention (T1), and at 1-month follow-up (T2). Results: The results of this trial demonstrated a significant decrease in pain intensity scores for the PMR group compared to the control group at both T1 and T2 (p < 0.05). Furthermore, the PMR group also exhibited significant improvements in pain interference with general activity, mood, relations with others, sleep, and enjoyment of life scores compared to the control group at both T1 and T2 (p < 0.05). Conclusion: The results of this trial suggest that the PMR technique may be an effective intervention for reducing pain intensity and improving pain interference with life activities in cancer patients receiving palliative care. However, further research is needed to provide more robust evidence for the effectiveness of this intervention.
