## What is RodentLimb?

From video to movement metrics—right on your iPhone.

RodentLimb is an AI-powered research tool that turns mouse videos into quantitative motor behavior measurements. Designed for neuroscience and preclinical research, it combines on-device pose estimation, visual review, and structured data export in one streamlined workflow.

THREE ASSAYS. ONE APP.

TAIL SUSPENSION TEST
• Quantify immobility duration, percentage, latency, and bouts.
• Examine movement patterns over time.
• Estimate hindlimb clasping and flag tail-climbing behavior.
• Review the tracked movement behind each result.

CYLINDER TEST
• Count left, right, and bilateral forepaw contacts.
• Quantify rearing and forepaw-use asymmetry.
• Calculate contralateral paw-use measures when the lesion side is specified.
• Inspect and manually correct individual contact events.

GAIT ANALYSIS
• Measure stride length, stride frequency, and walking speed.
• Explore stance, swing, duty factor, and base of support.
• Visualize footfall patterns and interlimb coordination.
• Examine gait variability, asymmetry, and speed-matched measures.

BUILT FOR RESEARCH WORKFLOWS

ON-DEVICE AI
Run pose estimation directly on your iPhone. No cloud processing or account is required.

VISUAL VERIFICATION
See tracked keypoints overlaid on the original video. Scrub through recordings, step frame by frame, and inspect individual events.

FLEXIBLE ANALYSIS
Adjust measurement parameters and recalculate results without repeating pose estimation.

BATCH PROCESSING
Import multiple recordings, organize subjects and experimental groups, and review your results in one place.

RESEARCH-FRIENDLY EXPORTS
Export summary measurements, detected events or strides, frame-by-frame keypoint data, and analysis methods as structured files for downstream research.

BUILT WITH SCIENTIFIC TRANSPARENCY
Explore measurement definitions, parameters, and methodological references within the app.

RodentLimb is intended for research use. Automated measurements depend on video quality, camera angle, and pose-tracking performance. Results should be visually reviewed and independently validated before scientific interpretation.

One mouse per video. Compatible with iPhone running iOS 17 or later.
