The term "Boston arm" refers to a type of prosthetic limb designed to provide assistance and functionality to individuals who have experienced amputation or loss of an arm. It is named after the city of Boston, possibly due to the historical significance and advancements made in the field of prosthetics in the healthcare institutions in the region.
A Boston arm is a highly sophisticated and advanced artificial arm, which is crafted with the goal of closely replicating the natural movement and functionality of a real human arm. It typically consists of a combination of mechanical, electrical, and electronic components that allow for a wide range of articulation and control.
The Boston arm is custom-made for each individual, taking into consideration their specific needs and requirements. It is designed to mimic the natural movement of the shoulder, elbow, and wrist, enabling the user to perform a variety of tasks and activities with ease. The prosthetic limb is usually attached to the residual limb through a socket system, ensuring a secure and comfortable fit.
Furthermore, the Boston arm may include additional features such as sensory feedback, which allows the user to perceive touch or pressure on the prosthetic limb, enhancing their sense of embodiment. The limb may also be equipped with advanced controls, such as myoelectric sensors, enabling users to control the arm's movements using muscle signals generated when contracting specific muscles in their residual limb.
Overall, the Boston arm represents a remarkable advancement in the field of prosthetics, providing individuals with amputations the opportunity to regain a significant level of independence and functional ability in their daily lives.
