  1. The interview can be started with the least difficult task, stepwise going towards the most difficult task or vice versa. It can be introduced as following: “Now we want to know what you have been doing between therapy sessions”. If the patient does not fill out the assessment on his or her own, the questions should be asked as follows: “Between therapy sessions, were you mostly lying in bed in order to recover” and so on. Regardless of the answer, continue to the next task because patients might sit and lay down a great amount of the time and would answer yes to both questions. Please always continue to the most difficult task if the patient’s mobility is good enough to theoretically undertake walks on his or her own. Be careful not to underestimate the patient’s physical activity
  2. The definition of sometimes and often is defined as follows: “yes, sometimes” should be scored if the task has been accomplished less than four times a week. “Yes, often” can be scored when the patient has done the task four and more times a week
  3. Severe cognitively impaired elderly might be assessed using proxies (i.e. relatives or nurses if applicable)
  4. Please note that it is irrelevant what the patient has done during therapy sessions. Instead, the questionnaire aims to assess physical activity, even in the context of participation with relatives
  5. Wheelchair use (not validated): what should be scored, if a patient is being pushed along the ward or even outside the hospital in a wheelchair, but is not able to leave the bed without assistance? Because the PAIR has not been developed as an assessment of physical function we believe that the activity and not the functional capabilities (even with the assistance of relatives or visitors) should be scored. However, if the patients was urged to go outside and if he/she was absolutely passive during the walk we would not regard this activity as physical activity in the sense of the ICF. Further studies are needed to clarify this issue
  6. The final score of the PAIR is the maximum score, not a cumulative score. For example: if the patient manages to undertake little walks on the ward every day, but, during the rest of the time sits in his chair, he or she would score 4 points
