Comparable items between the UPDRS-III and Body Motion Evaluation.
| | Functional modalities | UPDRS-III items | BME items | Description of BME items |
| | Upper extremity | Rigidity (upper limbs 3.3) | Shoulder flexion (right and left) | All are range of motion, measured in degrees | | Body bradykinesia (3.14) | Shoulder extension (right and left) | | Shoulder internal/external rotation (right and left) | | Maximum shoulder abduction (right and left) |
| | Lower extremity | Rigidity (lower limbs 3.3) | Bilateral squat depth | All measured in centimeters and inches | | Gait (3.10) | Lunge distance (right and left) | | Body bradykinesia (3.14) |
| | Trunk | Rigidity (neck 3.3) | Trunk rotation (right and left) | All measured in degrees | | Posture (3.13) | Trunk flexion | | Trunk extension |
| | Balance and posture | Postural stability (3.12) | Anterior-posterior hip displacement | Patients were asked to remain for 10 seconds with arms outstretched to the sides, eyes closed, and head tilted upward | | Posture (3.13) | Medial-lateral hip displacement | Hip displacement was measured in centimeters |
| | Gait | Arising from a chair (3.9) | Cadence | Strides/minute | | Gait (3.10) | Gait speed | Meters/second | | Freezing of gait (3.11) | Stride length | Centimeters | | Posture (3.13) | Step length (right and left) | Centimeters | | Body bradykinesia (3.14) | Step width (right and left) | Centimeters |
