AlphaFlex: Wearable Knee Function Analysis
IMU-based measurement platform for clinical-grade knee joint analysis in sports and healthcare.
About AlphaFlex
AlphaFlex is a wearable sensor platform that uses Inertial Measurement Units (IMUs) to capture precise knee flexion/extension and varus/valgus angles during sports, clinical assessments and rehabilitation exercises.
Unlike traditional motion capture systems requiring laboratory environments, AlphaFlex provides clinical-grade joint angle measurement in any setting – clinic, ward, or sports field. Data is captured wirelessly and processed in real time using validated biomechanical algorithms.
Independently validated by ATU Galway (Enterprise Ireland Innovation Voucher) and University of Galway (Data2Sustain)
How It Works
Clinical-grade joint angle measurement using validated inertial sensing technology.
Sensor Placement
Lightweight IMU sensors are attached to the thigh and lower leg using adjustable straps. No calibration blocks or external markers required.
Data Capture
Sensors capture 6-axis IMU data (accelerometer + gyroscope) at high frequency during dynamic movement, static holds, or gait analysis.
Algorithm Processing
Our proprieitary algorithm processes raw IMU data to compute accurate, drift-corrected joint angles for flexion/extension and varus/valgus axes.
Real-time Visualisation
Joint angle data is streamed wirelessly to the clinical dashboard, displaying real-time movement patterns with configurable reference ranges.
Clinical Reporting
Automated PDF reports compare patient measurements against normative data, supporting objective clinical assessment documentation.
Longitudinal Tracking
Repeated measurements enable objective monitoring of function and rehabilitation progress over time, supporting evidence-based treatment decisions.
Clinical Use Cases
Sports Medicine
Objective knee function assessment for athletes recovering from ACL, PCL, or meniscal injuries. Supports return-to-sport decision making with validated biomechanical data.
Orthopaedic Rehabilitation
Pre- and post-surgical knee function monitoring for total knee replacement, osteotomy, and arthroscopic procedures. Quantifies rehabilitation milestones objectively.
Clinical Research
Research-grade joint angle data for clinical studies, RCTs, and observational research. Validated algorithms ensure data quality suitable for peer-reviewed publication.
Research Backing
Algorithm Validation
Validation studies have confirmed the algorithm's accuracy against gold-standard systems, with mean angle errors below clinically significant thresholds across all planes of knee motion.
