A total of 55 patients and 49 family members completed the survey. Patients and family members reported that PT was necessary and beneficial to recovery, despite associating PT with difficulty, exertion, and discomfort. Patient perceptions were similar regardless of age or sex. Family members underestimated a patient's enjoyment of PT (P = .03). For individuals who required prolonged mechanical ventilation (> 14 days), patients reported that PT was more difficult (P = .03) and less enjoyable (P = .049), and family members reported PT as causing greater discomfort (P = .005). In addition, family members of patients who required prolonged mechanical ventilation felt that PT was less beneficial (P = .01).
