A combined active and passive leg prosthesis system is disclosed, and a method of performing a gait cycle by a leg prosthesis system is disclosed, for replacing a missing lower extremity of an individual to perform a gait cycle by the leg prosthesis system and/or the method. In at least one embodiment, the leg prosthesis system includes at least one movable joint, and a disconnectable active drive unit to drive the movable joint and a passive brake unit to brake the movable joint when the drive unit is disconnected.

1. A leg prosthesis system for replacing a missing lower extremity of an individual for performing a gait cycle, said leg prosthesis system comprising at least one movable joint, a brake unit arranged to brake a movement of the movable joint, andan active drive unit arranged to actively drive the movable joint by providing power to the movable joint, which power causes the movable joint to perform a movement, wherein the active drive unit is disconnectable from a driving relation with the movable joint,the brake unit acts on the movement of the movable joint when the active drive unit is disconnected from the movable joint, andthe leg prosthesis system is arranged such that during at least one mode of operation the active drive unit actively drives the movable joint during a first part of the gait cycle, and is disconnected from driving relation during a second part of the same gait cycle. 2. A leg prosthesis system as claimed in claim 1, wherein during said mode of operation the connection and disconnection of the drive unit is performed during each one of a plurality of consecutive gait cycles. 3. A leg prosthesis system as claimed in claim 2, wherein the leg prosthesis system further comprises a control system to control the active drive unit of said movable joint. 4. A leg prosthesis system as claimed in claim 3, wherein said control system is adapted to control the brake unit of said movable joint. 5. A leg prosthesis system as claimed in claim 1, wherein the leg prosthesis system comprises both a movable knee joint and a movable ankle joint. 6. A leg prosthesis system as claimed in claim 5, wherein said knee joint and ankle joint are each arranged with a disconnectable active drive unit and a brake unit and a common control system to control the movements of knee joint and ankle joint in a synchronised manner. 7. A leg prosthesis system as claimed in claim 3, wherein the leg prosthesis system comprises transducers for input data to the control system. 8. A leg prosthesis system as claimed in claim 6, wherein said knee joint and ankle joint move by switching between the associated active drive unit and brake unit during a gait cycle. 9. A method of performing a consecutive number of gait cycles by a leg prosthesis system, which replaces a missing lower extremity of an individual, said leg prosthesis system including at least one movable joint, a brake unit, and an active drive unit, the method comprising: actively driving the movable joint with the active drive unit by providing power the movable joint during a first part of each gait cycle, which power causes the movable joint to perform a movement;disconnecting the active drive unit from a driving relation with the movable joint during a second part of each the gait cycle; andbraking the movement of the movable joint with the brake unit when the active drive unit is disconnected from the movable joint. 10. A method as claimed in claim 9, wherein the leg prosthesis system comprises a control system for controlling the active drive unit of the movable joint. 11. A method as claimed in claim 10, wherein said control system is adapted to control the brake unit of the movable joint. 12. A method as claimed in claim 10, further comprising: supplying input data to the control system from transducers of the leg prosthesis system. 13. A method as claimed in claim 9, wherein the leg prosthesis system is arranged with both a movable knee joint and a movable ankle joint. 14. A method as claimed in claim 13, wherein said knee joint and ankle joint are each arranged with a disconnectable active drive unit and a brake unit and a common control system for controlling the movements of knee joint and ankle joint in a synchronised manner. 15. A method as claimed in claim 14, further comprising: driving and braking of the knee joint and ankle joint, respectively, during a gait cycle. 16. A leg prosthesis system as claimed in claim 1, wherein the active drive unit drives the movable joint to straighten and bend the movable joint.
