Assist in swing
The hydraulic cylinder system is responsible for gait speed, and the extension assist spring is responsible for holding the extended position to prevent buckling.
The combination of them provides a secure and comfortable swing.
I live in the cold area, so in the winter, I often shovel snow and walk on snowy road. For Symphony, because I can lock by myself, it is safe when it is snowing.
I have used various prosthetic knees and I have come to the Symphony knee.
I can walk naturally and work with it even in my field. It is useful.
What made me happiest was being able to go upstairs to my house and restart household work, such as hanging laundry out on the balcony. My husband did the housework while I was in the hospital, so I was happy to help my family again.
