Innovative mobility strategies for the patient with intensive care unit-acquired weakness: A case report

Abstract

Background and Purpose. Although the benefits of early mobilization in the intensive care unit (ICU) have been well documented in recent years, the decisionmaking process and customization of treatment strategies for patients with ICUacquired weakness have not been well defined in the literature. This case report will describe a patient with ICU-acquired weakness in the long-term acute care hospital (LTACH) setting and mobilization strategies that include novel devices for therapeutic exercise and gait training. Case Description. A 73-year-old, active woman underwent a routine cardioversion for atrial fibrillation but developed multiple complications, including sepsis and respiratory failure. The patient spent 3 weeks of limited activity in the ICU and was transferred to our LTACH for continued medical intervention and rehabilitation. A 4-phase graded mobilization program was initiated in the LTACH ICU. Within that program, the physical therapy interventions included partial weight-bearing antigravity strength training with a mobile leg press and gait training with a hydraulic-assist platform walker. Outcome. Before interventions, the patient had severe weakness (Medical Research Council [MRC] sum score of 18/60) and displayed complete dependence for all functioning. She progressed to being able to ambulate 150 ft (1 ft=0.3048 m) using a rolling walker with accompanying strength increases to an MRC sum score of 52/60. Discussion. This case report describes novel mobility strategies for managing a patient with ICU-acquired weakness. The application of a graded mobilization program using a mobile leg press and a hydraulic-assist platform walker was safe and feasible, and appeared to expedite the patient's recovery process while decreasing the amount of manual lifting for the therapists. © 2013 American Physical Therapy Association.
