UEF Parameters
Speed	Mean value of elbow angular velocity range (maximum minus minimum speed)	Toosizadeh et al., 2015b
Flexibility	Mean value of elbow flexion range	Toosizadeh et al., 2015b
Power	Mean value of product of the angular acceleration range and the range of angular velocity	Toosizadeh et al., 2015b
Rise time	Mean value of the required time to reach the maximum angular velocity	Toosizadeh et al., 2015b
Moment	Mean value of maximum moments on elbow within each flexion/extension estimated from moment of inertia of forearm and hand, and elbow motion	Toosizadeh et al., 2015b
Speed reduction	Difference in angular velocity range between the last and the first 5 s of elbow flexion as a percentage of the initial angular velocity range	Toosizadeh et al., 2015b
Speed variability	CoV of the angular velocity range during 20 s	Toosizadeh et al., 2015b
Flexion number	Number of flexion/extensions during 20 s	Toosizadeh et al., 2015b
Gait Parameters
Stride velocity	Average of gait speed (horizontal distance traveled divided by duration of walking) among strides	Aminian et al., 2002
Stride time	Time interval starts when one foot makes contact with the ground and ends when that same foot contacts the ground again	Aminian et al., 2002
Stride length	Distance traveled by the same limb between two successive heel contacts	Aminian et al., 2002
Double support	Duration of the initial and terminal double support when both feet are in contact with the ground as a percentage of the stride time	Aminian et al., 2002
Gait variability	CoV of gait speed among strides	Aminian et al., 2002

A reference for calculation procedure is presented for each parameter. CoV, coefficient of variation (standard deviation divided by the mean).
