The impact of functional exercise on the reversal of acromegaly induced frailty: a case report.

Acromegaly is an endocrine disease caused by the excess secretion of growth hormone and is responsible for the development of multiple comorbidities that can reduce physiologic reserve. The hypersecretion of growth hormone (GH) affects virtually every organ in the body and can predispose an individual to frailty; a state of vulnerability resulting from cumulative decline across multiple systems. Frailty results in a loss of physiologic reserve and vulnerability to adverse outcomes such as morbidity and mortality. Case Description: The patient was a 73-year-old male with acromegaly who declined into a cycle of frailty following coronary artery bypass graft (CABG) and aortic valve replacement surgery. Prolonged hospitalization and lack of adequate physical stress led to the depletion of reserve in the cardiopulmonary, cognitive, musculoskeletal, and neuromuscular systems, leaving a previously independent adult fully dependent for mobility. Outcomes: The patient participated in a twelve-week multicomponent physical therapy program in a skilled nursing facility. The exercise program was designed and administered to impact multiple systems and provide the necessary overload for adaptation. The patient demonstrated significant improvement in the Berg Balance Scale (BBS), Tinetti (POMA), Functional Outcome Scale (FOS), and returned to independent community ambulation.. Discussion: The case illustrates the effectiveness of a multicomponent functional-based exercise program to improve markers of frailty and reverse functional decline in a frail older adult with acromegaly.
