About Atlas5D

Atlas5D enables a new way to gather real-world information towards patient care and medical research. Many therapeutic areas, such as nervous system, cardiovascular, and bone and joint, lack technology to measure progression at home — especially over long durations of time. Echo5D by Atlas5D solves this problem by precisely measuring patient ambulation and dexterity at-home, without using wearables, requiring recharging, or invading privacy.
