Incidence and Determinants of Joint Contractures in Mechanically Ventilated ICU Patients

This prospective observational cohort study aims to evaluate the incidence and determinants of joint contracture development in mechanically ventilated adult patients admitted to the intensive care unit (ICU). Prolonged immobilization, deep sedation, and neuromuscular blockade are common in critically ill patients and may contribute to musculoskeletal complications, including joint contractures, which can adversely affect functional outcomes and rehabilitation after ICU discharge. Adult patients who are mechanically ventilated, immobilized, and have impaired consciousness will be consecutively enrolled and followed during their ICU stay. Joint range of motion will be assessed using standardized passive range of motion (PROM) measurements performed with a goniometer at predefined intervals by trained assessors. Joint contracture will be defined as a reduction of at least 33% in passive joint range of motion compared with normal reference values. This study is non-interventional, and all patients will receive routine ICU care and standard physiotherapy according to institutional protocols. No additional procedures or interventions will be applied for research purposes. Demographic characteristics, clinical variables, and ICU-related factors will be recorded to explore potential associations with contracture development. The findings of this study are expected to provide prospective data on the burden of joint contractures in mechanically ventilated ICU patients and to identify modifiable risk factors that may inform future preventive and rehabilitative strategies in critical care practice.
