Subjects who met inclusion criteria will be taken for this study from the Department of Medical Oncology and Department of Surgical Oncology in Sri Ramachandra Hospital. Subjects will be explained about the study and outcome of the study and written informed consent would be obtained. Based on the inclusion criteria subjects will be divided into 2 groups. Group A (Prehabilitation group) and Group B (Standard Physiotherapy group). Group A will receive prehabilitation and lymphedema education preoperatively 1 – 2 weeks prior to surgery by direct 1:1 education for about 30-45 minutes and participants are instructed to follow the exercises at home and are monitored through tele-communication and standard post-operative physiotherapy care will be given following surgery. Group B will receive standard physiotherapy care and lymphedema education. Both groups will be assessed shoulder ROM using goniometer, grip strength using handheld dynamometer, shoulder functional outcome using SPADI questionnaire, and arm circumference using inch tape during preoperatively (Experimental group: 1 – 2 weeks prior to surgery) (Control group: 1 – 2 days prior to surgery), post-operative day 1, post drain removal, and post 1 and 2 months of surgery. Awareness of lymphedema will be assessed by using Lymphedema Knowledge Survey before and after giving lymphedema education.
