effect of ckc and ws exercises on postural stability in unilateral post mastectomy lymphedema

Conditions: Postmastectomy Lymphedema

Summary: post-mastectomy lymphedema is one of the most common chronic complications that significantly impacts patients' quality of life following breast cancer surgery. postural stability is maintained through the intricate integration of muscular forces, sensory input from mechanoreceptors, and biomechanical feedback. closed kinetic chain (ckc) exercises play a crucial role in enhancing musculoskeletal stability by countering gravitational forces during both rest and movement. weight shifting and balance are fundamental components of functional movement. proprioceptive training, which focuses on improving body awareness and balance, is essential for developing trunk control

sixty patients who have unilateral post mastectomy lymphedema will participate in this study. their ages will range from 40 to 60 years. the patients will be subdivided randomly into four equal groups. 1.1.a- group a (n= 15) (ckc group): this group will include 15 patients who will receive closed kinetic chain exercises, in addition to complex decongestive therapy (cdt) for the treatment of lymphedema. cdt includes (skin care, manual lymphatic drainage, compression bandages, compression garments and exercises). the total exercise time will be 30 minutes, three times per week for eight weeks. 1.1.b- group b (n= 15) (ws group): this group will include 15 patients who will receive weight shifting exercises, in addition to complex decongestive therapy (cdt) for the treatment of lymphedema. the total exercise time will be 30 minutes, three times per week for eight weeks. 1.1.c- group c (n= 15) (combined group): this group will include 15 patients who will receive closed kinetic chain and weight shifting exercises, in addition to complex decongestive therapy (cdt) for the treatment of lymphedema. the total exercise time will be 60 minutes; 30 minutes of ckc and 30 minutes of ws exercise three times per week for eight weeks. 1.1.d- group d (n= 15) (control group): this group will include 15 patients who will receive complex decongestive therapy (cdt) for the treatment of lymphedema. cdt includes (skin care, manual lymphatic drainage, compression bandages, compression garments and exercises).
