AI-powered movement screening

Onescrin

AI that watches an athlete move
and tells the coach what to fix.

One phone video becomes a full screening report. Computer vision tracks every joint frame by frame, scores flexibility, jumps, speed and agility, and flags injury risk before it turns into an injury.

  1. 1

    Record

    Film a standard test on any phone.

  2. 2

    Track

    Maps the body in motion.

  3. 3

    Score

    Objective KPIs, not guesswork.

  4. 4

    Advise

    AI explains the risk and builds a plan.

Who We Are

New Stream Ltd. develops comprehensive software for the biomechanical analysis of body motions. To create practical solutions, our company conducts cutting-edge research in sports, health, and rehabilitation. We are also revisiting existing physical fitness assessment methods to make athletic performance measurements more accurate and comprehensive.

Our core is a video-based biomechanical analysis engine. A phone camera replaces lab equipment: our team researched and benchmarked several pose-estimation frameworks (MMPose, YOLOv8, Google MLKit) to find the combination accurate enough for sport-specific movement tests, then trained and tuned detection on athlete movement patterns — jumps, sprints, change-of-direction, mobility screens — so the same clip that a coach films on-field becomes lab-grade skeletal tracking.

Application Description

The Athlete Assessment Tool (AAT) is an innovative mobile platform designed for quick and accurate performance assessments using only a smartphone. It replaces traditional lab-based evaluations with real-time data processing and actionable insights, making it accessible, efficient, and cost-effective. AAT leverages AI and machine learning to create personalized training plans, optimize performance, and reduce injury risks.

Stations overview

The Stations feature allows coaches to split a large team into multiple stations. Each station is responsible for a specific set of tests, helping organize the workflow and speed up data collection when working with groups of athletes.

Station workflow

Within a station, coaches or assistants work with an assigned group of athletes: running tests, recording results, and tracking progress. This approach simplifies team coordination and reduces the workload on a single specialist.

Back Office

The back-office serves as the control center for the Athlete Assessment tool, where training programs are created, AI-driven workout allocations are managed, and coaches fine-tune plans. The web version is optimized for strategizing and refining performance plans, ensuring a comprehensive approach to athlete development.

Meanwhile, the mobile app functions as the field tool, enabling coaches to assess athletes, log sessions, track progress, and access reports. On-field data collection occurs through the app, while all strategic planning and performance optimizations are conducted via the back-office platform to maximize athlete potential.

    Coaches can create and manage testing sessions from either the mobile or web app. This page provides a clear overview of all test sessions — planned, in progress, processing, executed, or expired — so coaches always know the current status and can quickly return to any session to review data or results.

  2. Test Session Results

    It brings together athlete details, completed test types, and AI-generated performance metrics in one place. Coaches can quickly review key KPIs, compare left/right symmetry, track trends, and identify imbalances — then download reports or move seamlessly toward building a personalized practice plan based on the results.

  3. Practice Plan

    Coaches can review the AI-generated structure, add or remove recommended workouts, and adjust weeks, days, sets, reps, load, frequency, and rest — all in one clear layout. KPIs from test results remain visible to guide decisions, enabling quick customization and approval of a plan tailored to the athlete's needs.

  4. Share Your Practice Plan

    This step makes it easy to deliver the final plan to the athlete. Coaches can send it by email or share a secure link, so athletes can quickly access their workouts, understand expectations, and start training without confusion or extra steps.
