Effect of Early Mobilization on Respiratory and Limb Muscle Strength and Functionality of Nonintubated Patients in Critical Care: A Feasibility Trial

Table 4

Floor and ceiling effects on the use of MRC-s, FIM, FSS-ICU, ICF-BMS, and PFIT-s scales at the ICU admission and discharge.

Scales	Moment	Floor effect N observations (%)	Ceiling effect N observations (%)	Score range
MRC-s (score 60)	Admission	—	24 (60)	47 to 60
	Discharge	—	33 (82.5)	49 to 60
FIM (score 77)	Admission	1 (2.5)	14 (35)	11 to 77
	Discharge	—	25 (62.5)	38 to 77
FSS-ICU (score 35)	Admission	—	20 (50)	3 to 35
	Discharge	—	28 (70)	17 to 35
ICF-BMS (score 70)	Admission	3 (7.5)	—	6 to 66
	Discharge	21 (52.5)	—	6 to 47
PFIT-s (score 12)	Admission	—	4 (10)	4 to 12
	Discharge	—	22 (55)	6 to 12

MRC-s: Medical Research Council Score; FIM: Functional Independence Measure; FSS-ICU: Functional Status Score for the Intensive Care Unit; ICF-BMS: International Classification of Functioning, Disability and Health-Based Basic Mobility Scale; and PFIT-s: Physical Function ICU Test Score. Variables are expressed in absolute and relative frequencies.
