Targeted Physical Rehabilitation for Physical Function Decline in Patients with Schizophrenia: A Narrative Review

Prolonged hospitalization contributes to a decline in physical function and immobilization. This narrative review aims to explore physical rehabilitation approaches that address the specific characteristics of physical dysfunction in patients with schizophrenia. A literature review was conducted following an electronic search of PubMed for English-language articles published between January 2014 and January 2025. Based on the findings, a framework was constructed to categorize symptoms and physical challenges into three domains: (1) movement disorders and obesity induced by antipsychotic medications, which alter motor performance and lead to compensatory movements; (2) negative symptoms and cognitive impairments, which promote sedentary behavior and result in dysphagia, dynapenia, sarcopenia, and frailty; and (3) accelerated brain aging and disuse syndrome by schizophrenia, which impair neuromotor and cognitive function and increases the risk of physical dependency. These interconnected factors emphasize the need for targeted physical rehabilitation to maintain independence and reduce the risk of hospitalization. This review proposes a multidisciplinary approach involving psychiatrists, physical therapists, and occupational therapists, along with individualized nutritional support, as essential components of comprehensive rehabilitation strategies aimed at improving physical outcomes and reducing early mortality in this population.
