Which scale is commonly used to assess a patient's mobility level?

The Katz Index of Independence in Activities of Daily Living (ADL) scale is frequently utilized to evaluate a patient's mobility level because it focuses specifically on basic daily activities that are indicative of mobility and functional independence. This scale assesses an individual's ability to perform essential tasks such as bathing, dressing, toileting, transferring, continence, and feeding. The ability to execute these tasks effectively is strongly correlated with a patient's mobility status; therefore, this index serves as a vital tool for healthcare providers in determining the level of assistance a patient may need.

While other scales mentioned assess various aspects of health and function, they do not focus as directly on mobility. The Barthel Index, for example, also measures performance in daily activities, but it is more comprehensive and includes other factors. The Norton Scale primarily evaluates risk for pressure sores rather than mobility. Lastly, the McGill Pain Questionnaire is designed to assess the quality and intensity of pain, which is related to mobility but not directly a measure of mobility itself. Hence, the Katz Index stands out as the most appropriate choice for assessing a patient's mobility level directly.
