The MR4 Spring 2025 Release delivers a combination of new workflows and usability enhancements designed to streamline your research, clinical assessments, and ergonomic evaluations. From IMU-based Powers Running Analysis and single-sensor Sit-to-Stand testing to refined NIOSH calculations and reporting tools, this update is packed with features that boost efficiency and expand functionality—making it easier to collect, analyze, and report meaningful movement data.

Powers Running Assessment with Motion Sensors

1 Sensor Sit-to-Stand Analysis

Perform the Powers Running Assessment using Ultium Motion sensors to capture kinematic events without video. This IMU-based workflow mirrors the established Powers methodology and includes event-driven metrics, scoring, and visual reporting.

Quickly assess lower-body functional mobility with automated Sit-to-Stand analysis using a single IMU sensor—ideal for fast, objective clinical screening and performance tracking.

UI/UX Updates

Optimized Shared Database Access for Large Databases
Work more efficiently with high-volume datasets thanks to improvements in how the shared database indexes and loads large projects.

Updated Handling for NIOSH Zero Multipliers
To enhance interpretation and usability, any values that would yield a “0” multiplier are now capped at their maximum thresholds—ensuring the Lifting Index still flags high-risk tasks while maintaining output integrity.

Revised NIOSH Horizontal (H) Component Definition
Following updated guidance from NIOSH, the Horizontal (H) component is now calculated from the L1/S5 joint to the midpoint of the hand grasp, improving anatomical relevance and alignment with NIOSH’s original intent for the calculation.

Asymmetry Indices Added to Difference Formula List
A complete set of asymmetry indices has been added to the formula options for Channel and Average Curves, allowing for more flexible comparison of movement patterns. Descriptions were also updated to improve usability and clarity.

Improved Access to Report Selection Menu from VIEW
You can now launch the Report Selection Menu directly from the VIEW screen, streamlining the path to analysis and report generation.

Clearer Communication (COM) Error Messages
Camera communication-related errors—such as those caused by missing device connections—now provide more informative messages to help users identify and resolve setup issues quickly.

Simplified FDM Sync Options
The synchronization interface for FDM devices has been simplified for quicker setup and reduced configuration errors.

Software Settings Now Open to Common Tab
The Software Settings menu now defaults to the Common tab on first open, making key options faster to find and adjust.

“Settings” Renamed to “Configuration” in Protocol Menu
For better clarity, the “Settings” menu in protocol setup has been renamed to “Configuration” to reflect its intended purpose.

Protocol Naming Now Required on Creation
Users must now enter a protocol name when creating new configurations, helping avoid unnamed or accidental saves.
