Walking across a room is something most people do without thinking. For 33-year-old Sumit, it had long been a daily struggle requiring effort, support, and determination. A survivor of polio since the age of one, Sumit lived with weakness and deformity in his left lower limb for decades.

Sumit was affected by polio in early childhood, which left his left leg weak and deformed. Despite undergoing multiple corrective surgeries over the years, daily life remained challenging. He had reduced ankle movement, foot drop, and his heel could not touch the ground. Walking short distances caused pain and fatigue, and he often had to support his leg with his hand to move forward. Over time, he developed post-polio syndrome, a condition in which muscle weakness worsens many years after the initial polio infection, making activities like climbing stairs, maintaining balance, and walking increasingly difficult.
