Intended Use

DARI Health is a computer and video system used to quantify and graphically display human movement patterns and techniques for uses such as assessment and training of limb or body motion in pre/post rehabilitation evaluation, physial therapy, and the like.

Device Story

DARI Health is a markerless, 3D human motion capture and analytical software system. It utilizes off-the-shelf video cameras and computer hardware to record patient movement in real-time. The system generates a digital skeleton to identify joint centers and segments for the cervical spine, trunk, and extremities. Data is processed by the DARI Insight Engine—either locally or via a secure cloud-based server—to calculate kinematics and kinetics, including ground reaction forces. Outputs are displayed as raw datasets or graphical reports via a web portal or local application. Used in clinical settings (e.g., physical therapy) by healthcare providers to monitor patient progress and inform clinical decision-making. The system requires no physical contact with the patient and delivers no energy, providing a non-invasive method for biomechanical assessment.

Clinical Evidence

Bench and clinical studies demonstrate equivalence to marker-based systems and force plates. In a study comparing DARI to a marker-based system, no statistically significant differences were found in joint angles (p=0.33). Comparison against force plates showed no significant differences in peak/mean force (p>0.05) with high correlation (r=0.995, r²=0.989). Repeatability study of 9,120 bone segments showed joint center/segment length identification within 0.811mm (99% confidence) and 1.02% total skeletal change between sessions, exceeding predicate marker-based repeatability.

Technological Characteristics

Markerless 3D optical motion capture system. Uses off-the-shelf cameras and Linux-based computing hardware. Performs 3D trajectory reconstruction and kinetic calculations (including ground reaction forces) via digital skeleton modeling. Connectivity via local database or secure cloud-based server. Non-sterile, non-contact, no energy delivery. Complies with IEC 60601-1 and IEC 60601-1-2. Software developed per ANSI/AAMI/IEC 62304.

Indications for Use

Indicated for assessment and training of limb or body motion in pre/post rehabilitation evaluation, physical therapy, and similar clinical applications for patients requiring movement pattern quantification.

DARI's existing motion capture technology system has been utilized in non-clinical biomechanical research, fitness applications, and performance evaluation for may years. In view of experience with this technology, its numerous uses, and its demonstrated value, there's an need for the development of its use in clinical applications.

DARI Health is a "markerless," three-dimensional human motion capture and analytical software system that uses off-the-shelf video cameras, off-the-shelf computer hardware, off-theshelf motion analysis software, and proprietary DARI Health Software (consisting of DARI Connect, DARI Capture plug-in, DARI Insight Engine, and DARI Rerort Engine) or DARA quantify, and document full-body human kinematics and kinetics during patient movement

Motions are recorded in real-time, using a digital "skeleton" to identify joint center and segment data for the cervical spine, upper extremity, trunk, and lower extremity of the paint. The captured video can be viewed after recording has ended or at some later point.

During movement, the DARI Health interfaces with the capture software (off-the-shelf, Captury Live) tracks all segments and joint centers as they move in all planes of more the with resulting output is sent to The DARI Insight Engine processing software-either housed it ally on the computer used for capture or in a security-compliant, cloud-based server-where thered drant can be used to calculate all kinetic data produced during the revor d more one more one Such data is then displayed in different report formats-from large, raw datasets to simple, grahital reports that track key biomechanical metrics.

Healthcare providers can access patient biomechanical data remotely through a secure webportal or locally on the computer database application to monitor patient progress and view prior or current motion analyses.

There is no direct contact with the patient by the DARI Health system, and no energy is delivered to the subject at any point during the usage of the system.

{5}------------------------------------------------

#### 7. Intended Use

DARI Health is a computer and video system used to quantify and graphically display human movement patterns and techniques for uses such as assessment and training of limb or body motion in pre/post rehabilitation evaluation, physical therapy, and the like.

# 8. Technological Characteristics and Substantial Equivalence Evaluation

The technological characteristics of the DARI Health System device are based on the capture of three-dimensional motion information obtained from the subject under study. The video feed from the patient in motion is then recorded and stored on a computer where it is available for analysis of human motion using the DARI Health product. The DARI Insight Engine provided by DARI Health is used for data presentation to the healthcare professional. The data are accessible from a remote, security-compliant server for remote evaluations by the healthcare professional.

The DARI Health is substantially equivalent in terms of intended use, operating principles, and operational specifications to the Peak Motus Motion Measurement System (K030714) which is a legally marketable Optical Position/Movement Recording Systems classified pursuant to 21 C.F.R. §890.5360 under Product Code LXJ. As with the Peak Motus device, the DARI Health is intended to be used to quantify, analyze, document for remote access, visually display threedimensional human kinematics, kinetics, and patient performance metrics related to human movement patterns for uses such as assessment and training of limb or body motion in applications where such analysis is relevant to the clinician's decision-making processes.

This equivalency is summarized in the Tables below where Table 1 discusses the equivalency of the indications for use between the DARI device and the predicates. Table 2 discusses the technological characteristics between the DARI device and the predicates to demonstrate substantial equivalency.

#### 9. Summary of Performance Data

DARI Health performance characteristics have been verified by independent, peerreviewed studies proving the accuracy of the system's calculations of human kinematics and kinetics as compared to both traditional, gold-standard marker-based analysis and forces plate output. Likewise, DARI Health internal studies demonstrate repeatability metrics that or or exceed predicate and motion analysis industry standards. In addition, software validation a ot testing were completed for the device and functioned as intended and all results onsemally were those expected.

- a. Non-Clinical Performance Summary

{9}------------------------------------------------

no safety issues associated with its use. The DARI Health complies with IEC 60601-1 and IEC 60601-1-2.

#### Effectiveness

Bench testing demonstrates the DARI Health motion capture methodology's accuracy in representing and tracking digital skeletal segments.

- b. Clinical Performance Summary
#### Effectiveness

Clinical studies demonstrate the equivalency to predicate marker-based capture of human kinematics and industry-standard force plate output for evaluation of human kinetics.

Specifically, when compared to a predicate marker-based Vicon (Peak Motus) system in an independent, peer-reviewed study, the DARI Health system showed no statistically significant differences in the clinically relevant joint angles being measured for investigation (p =0.33).

The DARI Health system was also tested against standard force plate output in an independent, peer-reviewed study, where DARI's force calculation methodology demonstrated no statistically significant differences in peak force, mean force, or now force as compared to simultaneous measurements derived from a force plate (p > 0.05). Additionally, comparison of force-time curves with regression yiald ( > > 0.03). correlation between modalities (r = 0.995, 2 = 0.989, SEM = 11.1 NN.

A clinical study also supports the repeatability of the DARI Health System.

Specifically, the repeatability of segment length and joint center calculation over successive scans of 9,120 bone segments demonstrated the ability to identify the joint centers and segment lengths within 0.811mm with 99% confidence, exhibiting only 1.02% total skeletal change between sessions with 0.002 mm of variance. This exceeds prelicate repeatability associated with marker analysis and inter-test repeatability of goniometers claimed by predicate JRS v2.0.

10. System Validation for Software Design, Documentation, and Hazard Analysis

The DARI Health software is of "modcrate" level of concern based upon FDA Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices (2005). Consistent with FDA guidance and other applicable requirements, all hazards have been mitigated through appropriate controls, product labeling, while maintaining sufficient secve to may see protect the software and data.
