Primary Outcome Measures
NameTimeMethod
Change in Disability Rating ScaleBaseline, 1 week, 2 weeks, 3 weeks, 4 weeks

The primary outcome measure will be the change in Disability Rating Scale over 4 weeks. The Disability Rating Scale is a commonly used and reliable instrument for monitoring minor changes occurring throughout the course of a patient's recovery (Rappaport et al., 1982).

Secondary Outcome Measures
NameTimeMethod
John F Kennedy Coma Recovery Scale RevisedBaseline, 1 week, 2 weeks, 3 weeks, 4 weeks
Functional Independence Measure (FIM)Baseline, 1 week, 2 weeks, 3 weeks, 4 weeks
Functional Assessment Measure (FAM)Baseline, 1 week, 2 weeks, 3 weeks, 4 weeks
Orientation Log (O-Log)Baseline, 1 week, 2 weeks, 3 weeks, 4 weeks
