GemRed Digital Goniometer for Physical Therapy

The GemRed Digital Goniometer is engineered specifically for physical therapists, rehabilitation clinics, and ergonomic specialists to deliver fast, precise joint range-of-motion (ROM) measurement. Clinical research consistently demonstrates that digital goniometers achieve excellent reliability (ICC > 0.99) and minimal measurement error—often outperforming universal and inclinometer methods in both accuracy and repeatability.

Equipped with ±1° accuracy and 0.1° resolution, the GemRed device offers one-handed operation, memory holding, and Bluetooth-compatible data export to track patient progress digitally. Unlike manual goniometers—which often exhibit inter- and intra‑tester variability of up to 5–10°, this smart instrument ensures consistent and objective ROM assessment across shoulder, knee, hip, wrist, and spinal joints.

Key Features:

• ±1° accuracy with 0.1° resolution

• Exceptional test-retest reliability (ICC > 0.99) with low SEM (≤ 1°)

• Bluetooth export to clinical apps or CSV reports

• Memory recall for multiple previous readings

• Ergonomic, single-hand operation for real-world clinical use
