Excelsheets and macros

A. General issues

# Observation Examples
A1. Marker placement does not reflect joint angles Cervical Flexion/Extension
Cervical Lateral/Flexion
Cervical Rotation
Shoulder Flexion/Extension
Shoulder Abduction
A2. Level of confidence for stats with selected sample size is unknown. Minimum angle
Maximum angle
Maximum velocity
Coefficient of variation

B. Statistical issues in Excel-sheets:

# Observation Examples
B1. Bias in % to Norm (narrow angles amplify the bias; dependent on chosen coordinate system) Finger DIP Flexion/Extension
B2. Bias in % to Unaffected  
B3. Bias in Coefficient of Variation Shoulder Flexion/Extension
Shoulder Rotation
Wrist Radial/Ulnar Deviation
Wrist Radial/Ulnar Deviation Velocity
Finger PIP
Finger MP
B4. Bias in Summary residual dysfunction  
B5. Bias in Summary conclusion  
B6. Bias in Summary coefficient of variation  
B7. Bias in Summary maximal effort  
B8. Repeatability of Coefficient of Variation Wrist Flexion/Extension
Finger DIP/PIP/MP Flexion/Extension
Thumb IP/MP Flexion/Extension

C. Specific issues in Excel-sheets:

# Observation Examples
C1. Angles are "mirrored" in undefined axis Cervical Rotation
Shoulder Flexion/Extension
Shoulder Abduction Velocity
Shoulder Rotation
Shoulder Rotation Velocity
Wrist Ulnar/Radial Deviation
Wrist Supination/Pronation
Wrist Supination/Pronation Velocity
C2. Angular velocity is not derivative of corresponding angle. An angular velocity should be zero when angle=min or angle=max. An angular velocity should be positive when angle is going "up" and negative when angle is going "down". Shoulder Flexion/Extension Velocity
Shoulder Abduction Velocity
Shoulder Rotation Velocity
Wrist Flexion/Extension Velocity
Wrist Radial/Ulnar Deviation Velocity
C3. Higher velocity reported for slower movement  
C4. Summary does not correspond to chart Thumb IP Flexion/Extension
