1. Hardware Specifications

1.1 Walkway Platform

• Length: ~105–130 cm depending on model/configuration
• Width: ~10 cm walking area for mice; ~12 cm for rats
• Height: ~10 cm
• Material: Tempered glass plate with LED illumination for FTIR
• Target box

1.2 Camera

• Type: High-speed camera
• Mount: Located under the walkway to capture ventral (bottom) paw print images
• Frame Rate: ~100 fps
• Resolution: High enough to discriminate paw contacts clearly (1920×1080)
• Camera View: Captures ventral view of paw contacts

1.3 Green Light Paw Contact (Stance)

• The CatWalk walkway is a glass plate lit with green LEDs from the side
• When the paw touches the glass, light is scattered at the contact point (due to pressure breaking total internal reflection). This produces green illuminated paw prints in the video. These represent stance phase
• This green is typically 520–540 nm LED light (standard high-brightness green)

1.4 Top Red Light

• Illuminate the animal body without interfering with paw detection
• This light does not detect paw contact

2. Software (ConductVision)

2.1 Latest and Best AI Technologies

• For CatWalk analysis, ConductVision uses CNN-based paw segmentation plus pose tracking as an optimal solution
• 100% accuracy

2.2 Key Capabilities

• Automatic detection of paw contacts
• Classification of paws (LF, RF, LH, RH)
• Stride segmentation
• Calculation of temporal, spatial, kinetic, and coordination parameters

2.3 Gait Parameters Measured

Spatial Metrics

• Paw print area
• Print length, width
• Stride length

• Base of support (stance width)

Temporal Metrics

• Stance time

• Duty cycle

Coordination Metrics

• Regularity index
• Sequence patterns
• Inter-limb coupling

Intensity (Kinetic) Metrics
