Progressive Mobilization With Dose Control and Training Load in in Critically Ill Patients

Effects of the Addition of a Protocol of Progressive Mobilization With Dose Control and Training Load in in Critically Ill Patients: Randomized Controlled Trial

Immobilization and bed rest of patients in intensive care units (ICU) increases their risk for muscle dysfunction and prolonged mechanical ventilation, leading to physical deconditioning and loss of functionality. Active mobilization is a therapeutic strategy that typically involves exercises in which the patient uses his or her own strength and muscular control, is a feasible, safe, and low-cost intervention to improve muscle dysfunction and disability in patients at the ICU. Despite scientific advances, the current description and prescriptions of exercises at the ICU remain incomplete with respect to the control and the description of the variables of training load (volume and intensity), programming, and progression.

This prospective double-blind (patient and evaluator). This study will be conducted in accordance with Consolidated Standards of Reporting Trials recommendations. The trial will be performed at the University Hospital Professor Edgard Santos in Salvador, Bahia, Brazil. This study was approved by the institutional hospital ethics committee (approval reference number 2.371.933). Before enrollment, written informed consent will be obtained from participants or their legal guardians.

These patients will receive standard rehabilitation delivered by non-study physiotherapist. In addition, the patients will undergo a protocol of progressive mobilization with individualized dose control and training load stratified according to functional levels and performance.

Will be applied once a day, 5x/ week, performed into 4 levels: N1 (bridge and rolling for both sides); N2 (transfer training from lying down to sitting on both sides); N3 (sit and stand up from a chair); N4 (running training). According to their functional level, patients will perform, once a day, 8 sets of each movement, alternating 20 seconds of execution with 10 seconds of rest. Patients will be stimulated constantly to perform the movements with the highest possible speed. If the patient performs adequately within of your level functional level, can will progress in level, if can not progress, there will be an increase in training volume within the level itself. Adequate performance within the functional level means that the patient is able to complete more than eight sets of exercise and does not present increased sensation of pain, present sensation of perceived exertion within the safety limit of the protocol (Borg ≤ 6).

Functional Status Measured Using Functional Status Score for the Intensive Care Unit (involves five functional tasks (rolling, supine to sit transfer, sit to stand transfer, sitting on the edge of bed and walking). Each task is evaluated using an 8-point ordinal scale ranging from 0 (not able to perform at all) to 7 (complete independence)

Surgical Optimal Mobilisation Score (SOMS) level algorithm for goal-directed mobility ranges from '0-No mobility' to '4-Ambulation'. The intermediate steps are '1-Passive Range of Motion,' '2-Sitting,' and '3-Standing.'

Health-Related Quality of Life will be measured by a questionnaire 36-item Short Form Health Survey. The SF-36 is a widely used generic instrument for evaluating HRQoL, consisting of eight subscales evaluating specific health status domains and two summary scales, a Physical Component Summary and a Mental Component Summary. Scores on the SF-36 range from 0 to 100, with higher scores indicating better health status.
