Feasibility of Combining Functional Mobilisation with Resistance and Endurance Training for Mechanically Ventilated Patients in Intensive Care Unit Setting-A Pilot Study.

Intensive-care-acquired weakness resulting in functional impairment is common in critical care survivors. This study aims to evaluate the feasibility of a combined early functional training with endurance and resistance training and its effect on the functional outcome. It is a pilot study performed in a 39-bed Medical and Surgical Intensive Care Unit (ICU). Patients who were premorbidly independent and were mechanically ventilated for ≥24 h were recruited to receive functional mobilisation (sit out of bed, ambulation), endurance (bed cycling), and resistance training (selected upper and lower limb muscle training using weights). The primary outcomes were feasibility of training, muscle strength, handgrip strength, quadricep strength, and Functional Status Score-Intensive Care Unit (FSS-ICU) collected at the first assessment in the ICU, at the ICU discharge, and at hospital discharge. Secondary outcomes were functional capacity (6-Minute Walk Distance) and quality of life measures, EQ-5D, at hospital discharge and at 3 months. Out of the 11 patients, 6 (54.54%) patients achieved level 2 functional mobilisation, 2 (18.18%) patients achieved level 2 resistance training, and 1 (9.09%) patient achieved level 2 endurance training. There were no significant differences in the medical research council (MRC) score, quadricep strength, and handgrip strength between the first assessment in the ICU, at the ICU discharge, and at hospital discharge. However, there was a significant difference in FSS_ICU ( < 0.008) from the first assessment in the ICU up to hospital discharge. EQ-5D visual analogue scale also showed a change of 8.5% at 3-month follow-up. 6MWD showed significant difference ( < 0.043) at 3-month follow-up compared to that at hospital discharge. The study found low compliance to resistance and endurance training in patients with mechanical ventilation. However, functional mobilisation in terms of sit out of bed was possible in more than half of the recruited patients.
