LTI introduced the Boston Digital Arm System early in 2001. This state-of-the-art prosthetic system incorporates microprocessor technology for improved performance and optimal patient adjustment. The system uses the same drive mechanism as the Boston Elbow II because of its long history of reliable service. Also, this drive unit provides greater torque than any other powered prosthetic elbow on the market today - a feature most users soon recognize as a significant benefit. The Boston Digital Arm is not just for positioning a terminal device like many other elbow prostheses. This system can perform work, whether it be on-the-job, at home or doing hobbies.

The Boston Digital Arm System has many advanced features and capabilities. It can control up to four other prosthetic devices in addition to the elbow itself. For example, hands, grippers, wrist rotators, shoulder lock actuators, etc. can be operated through the Boston Digital Arm. And, these devices can be sequentially selected and operated by the user through co-contraction switching, a feature no other system can provide. A variety of other advanced control features are also available.

The Boston Digital Arm System is actually a platform for upper-limb prosthetic control. The on-board microprocessor enables the prosthetist to evaluate the patient for suitable muscle sites and then try various control strategies until a suitable one is found. This is done through the proprietary software provided with the system. Through the user-friendly graphical interface screens, the practitioner views the patient’s muscle signals and makes adjustments. If a different control strategy is preferred, he simply down-loads a new strategy to the prosthesis - a 5 second task.
