For certain medical purposes, such as enrolling individuals in medical trials and evaluating them for placement in housing, a concise means of communicating their ability to carry on typical life activities is needed. Several scales have been developed for this purpose.
|0||No symptoms. Fully active, able to carry on all pre-disease activities without restriction.|
|1||Symptomatic. Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, e.g., light housework, office work.|
|2||Symptomatic. Ambulatory and capable of all selfcare but unable to carry out any work activities. Less than 50% of waking hours in bed.|
|3||Capable of only limited selfcare. Confined to bed or chair more than 50% of waking hours.|
|4||Completely disabled. Cannot carry on any selfcare. Totally confined to bed or chair.|
|100%||normal, no complaints, no sign of disease|
|90%||capable of normal activity, few symptoms or signs of disease|
|80%||normal activity with some difficulty, some symptoms or signs|
|70%||caring for self, not capable of normal activity or work|
|60%||requiring some help, can take care of most personal requirements|
|50%||requires help often, requires frequent medical care|
|40%||disabled, requires special care and help|
|30%||severely disabled, hospital admission indicated but no risk of death|
|20%||very ill, urgently requiring admission, requires supportive measures or treatment|
|10%||moribund, rapidly progressive fatal disease processes|
