Functional Recovery of a Patient With Anorexia Nervosa: Physical Therapist Management in the Acute Care Hospital Setting

Abstract

Abstract Background and Purpose People with severe, long-standing anorexia nervosa (AN) often develop physical manifestations of medical starvation. Functional deficits are not well described, and little information is available to guide physical intervention. This case report describes the physical therapy clinical decision-making process and intervention provided to a patient with severe AN. Case Description The patient was a 48-year-old woman admitted to an acute care hospital with medical complications associated with AN and requiring medical stabilization. On admission, she was unable to complete basic functional activities (eg, bed mobility, transfers, ambulation). She was considered at risk for falls, with a score of 17 on the Performance-Oriented Motor Assessment (POMA) and a score of 19.27 seconds on the Timed “Up & Go” Test (TUG). Physical therapist examination and intervention focused on functional testing and training, strengthening, and postural stability training for return to independence. Outcomes In 9 weeks, the patient returned to independence in basic activities of daily living, as measured by 3 items from the motor domain (bed mobility, transfers, and ambulation) of the Functional Independence Measure, with improvements from 1 (“total assistance”) to 6 (“modified independence”) on each item. Postural stability improved to “low risk” for falls (POMA score of 24). Her TUG score improved to 11.00 seconds. Walking speed improved from 0.35 to 0.81 m/s. Once she attained medical stability, she was discharged home with her parents with outpatient services. Discussion Physical therapist management of this severely deconditioned patient hospitalized with severe AN focused on the restoration of functional activities, with intervention intensity being guided by physiologic responses. Traditional aerobic and endurance training were de-emphasized to minimize kilocalorie expenditure and tendencies toward exercise compulsion in this patient population.
