The Aspire P1 Knee is a pneumatic polycentric knee joint featuring a durable aluminum frame. It is specifically designed with increased ground clearance to enhance stability and promote a more confident, natural gait. The Aspire P1 Knee offers independent adjustment of flexion and extension. It features adjustable geometry with a stance release setting for enhanced functionality. Its slim design ensures a sleek and streamlined profile. functions: 1. Pneumatic Cylinder and Air Pressure The knee joint has an internal pneumatic cylinder that is filled with air to create pressure. This air pressure controls the resistance during the movement of the knee, influencing how the knee bends (flexion) and straightens (extension). The amount of pressure in the cylinder can be adjusted to suit the user’s needs. 2. Flexion and Extension Control During flexion (bending of the knee), the air pressure can be adjusted to provide a controlled, smooth motion. This helps to limit the speed at which the knee bends, offering a more natural gait and preventing rapid movement that could cause instability. During extension (straightening of the knee), the air pressure helps control the speed of the leg’s extension and may provide additional support to prevent hyperextension. 3. Stance Release and Swing Phase Some pneumatic knee joints have stance release settings, which help adjust the knee\'s behavior during the stance phase (when the leg is supporting weight). This setting can make it easier to maintain stability when standing and walking. In the swing phase, when the leg moves forward, the air pressure can help regulate the knee’s movement to ensure smooth transitions and allow for more fluid walking patterns. 4. Adjustable Settings Many pneumatic knee joints offer adjustable settings that allow the user to modify the air pressure to their preference. This allows customization of the knee joint\'s response to different activities and walking speeds, making it more adaptive to individual needs. # pneumatic knee joint #aspire P1# #artificial limb # low cost # # very durable # insole for foot #
