Karnofsky Performance Scale (KPS)

The Karnofsky Performance Scale (KPS) is a tool doctors use to measure a patient’s ability to carry out daily activities and their overall physical functioning. It ranges from 0 to 100, with higher scores indicating better health and independence. For example, a score close to 100 means the person can carry on normal activities without assistance, while lower scores indicate increasing levels of disability or need for help. The KPS helps healthcare providers assess prognosis, plan treatment, and monitor changes in a patient’s condition over time.
