Effect of CKC and WS Exercises on Postural Stability in Unilateral Post Mastectomy Lymphedema

This study is testing two types of physical exercises to improve balance and posture in women who have had a mastectomy (breast removal surgery) and developed arm lymphedema (swelling caused by lymph node removal). The exercises are closed kinetic chain (CKC) exercises and whole-body stability (WS) exercises. **You may be eligible if...** - You are a woman between 40 and 60 years old - You have had a unilateral (one-sided) mastectomy with lymph node removal - You have moderate arm lymphedema as a result - Your BMI is below 30 - You are able to communicate and follow instructions **You may NOT be eligible if...** - Your cancer has spread to other parts of the body (metastases) - You have a difference in leg length - You have a vestibular (inner ear), neurological, or orthopedic condition affecting balance - You have had spine surgery that limits movement - You have a psychiatric disorder - You have had a bilateral (both sides) mastectomy - You have peripheral nerve damage or significant cognitive problems - You take medication that affects balance - You have severe arthritis in your lower limbs Talk to your doctor to see if this trial is right for you.
