Outcome Measure Description Used in Study
Direct Strength Measures
Myometer Isometric force of quadriceps femoris muscle at 90° measured in kg. [32] B
MRC score The sum of MRC scale in four muscles. Two in the right upper extremity and two in the right lower extremity. Maximum score 20. [32] A, G
MRC index The MRC score divided by the maximum possible score of 20 then multiplied by 100 to give a percentage representation of the MRC score. [32] B
Average muscle score Called Strength score in previous trials.[33] This is the mean grade of 34 tested muscles on a ten point scale (modified from the MRC system). N
Functional Measures
Timed gait Number of seconds needed to walk for 10 metres. A, B
Timed stairs Number of seconds needed to walk up four stairs. A, B
Timed chair Number of seconds needed to rise from seated in a chair to standing. A, B
Timed Gower Number of seconds needed to rise from a sitting position on the floor to standing. A, B
Graded gait A score assigned for 10 m of walking. Points assigned for increasing dysfunction for a range between zero and seven. [32] A, B
Graded stairs A score assigned for walking up four stairs. Points assigned for increasing dysfunction with a range between zero and seven. [32] A, B
Graded chair A score assigned for rising from a chair to standing. Points assigned for increasing dysfunction with a range between zero and six. [32] A, B
Graded Gower A score assigned for rising from a sitting position to standing. Points assigned for increasing dysfunction with a range between zero and seven. [32] A, B
Others
