Each of the four studies selected used different outcome measures and varying physiotherapy treatment to determine whether exercise intervention is beneficial. The papers have been chosen as the data from each was collected via patient’s medical records and all of the studies are cohort in nature with positive control groups. This made the data more easily comparable, as cross sectional studies were eliminated and none of the papers used a blinded trail or a credible method to randomize the groups. Malkoc, Karadibak and Yildim. (2007) carried out a study to determine the effect of physiotherapy on ventilator dependency and the length of stay in an intensive care unit. Clear outcome measures were used on 510 patients which determined the effectiveness of the treatment, involving chest physiotherapy with some mobilisation. The researchers concluded that there was a significant difference in the control and intervention groups with the length of stay in the intervention group being significantly lower (P < 0.05). The study listed clear inclusion and exclusion criteria stating that patients were not to be selected if they had acute respiratory problems, or whether the patients had sustained any injury which did not allow chest physiotherapy to be provided. Inclusion criteria was that the patient had to be mechanically ventilated and
