Case Studies

Background and Purpose: Individuals with critical illness experience dysfunction of many body systems including the neuromuscular system. Neuromuscular impairments result in a syndrome referred to as intensive care unit (ICU)–acquired weakness, which may lead to difficulty with activities and participation. The purposes of this case series were to (1) describe safety and feasibility of physical intervention in individuals with ICU-acquired weakness mechanically ventilated for at least 7 days and (2) characterize physical therapist management and patient outcomes.

Case Description: Nineteen patients with ICU-acquired weakness who required mechanical ventilation for at least 7 days were enrolled over a 1-year period.

Intervention: Physical therapy (PT) was provided 5 d/wk for 30 minutes per session.

Outcomes: Outcome measures included manual muscle tests and item scores from the Functional Independence Measure. Participants completed 170 PT sessions. Only 20 sessions (12%) were stopped before 30 minutes. Seventeen participants survived to discharge; no PT-related adverse events occurred. At discharge, participants who went home showed a trend toward greater independence and strength than those who were discharged to another level of care. Median total hospital days was 28 for those discharged to home and 22 for those discharged to other level of care.

Discussion: This case series demonstrates safety and feasibility of PT intervention for patients with ICU-acquired weakness requiring mechanical ventilation for at least 7 days. The examination and intervention procedures are described and could be implemented with other similar individuals in the hospital setting. Future studies should investigate frequency and duration of physical intervention, both during hospitalization and postdischarge, and how these factors influence outcomes.
