Background: Breast cancer is one of the most common malignancies among women, and Modified Radical Mastectomy (MRM) remains a frequently performed surgical procedure. Post-operative patients often experience significant sleep disturbances and cancer-related fatigue, which negatively affect recovery and quality of life. Non-pharmacological relaxation techniques such as Benson Relaxation and Progressive Muscle Relaxation (PMR) have shown potential benefits in managing these symptoms.

Aim: To compare the effectiveness of Benson Relaxation Technique and Progressive Muscle Relaxation Technique on sleep quality and fatigue reduction in patients following Modified Radical Mastectomy.

Materials and Methods: An experimental study was conducted on 38 female patient’s post-MRM, aged above 18 years, selected through convenient sampling from the cancer department of SJS Hospital. Participants were randomly divided into two groups (n=19 each). Group a received Progressive Muscle Relaxation and Group B received Benson Relaxation Technique, administered four sessions per week for four weeks. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) and fatigue was evaluated using the Multidimensional Fatigue Inventory (MFI-20). Pre- and post-intervention data were analyzed using paired and unpaired t-tests.

Results: Both groups demonstrated statistically significant improvement in sleep quality and fatigue levels following intervention. However, the PMR group showed a greater reduction in PSQI and MFI-20 scores compared to the Benson relaxation group, indicating superior effectiveness in improving sleep quality and reducing fatigue.
