Ottobock Microprocessor Controlled C-Leg© - Frequent Questions

Specialized Gait Training

Optimal use of the C-leg requires the specialized assessment of your gait and posture and your use of the C-leg in a variety of places and terrain.

Q: Why do Walking habits on your ‘old knee’ affect the C-leg?
If you have worn a prosthesis for some time, using a different knee component, it is highly likely that you have transferred your old walking habits and style onto your new C-leg prosthesis. To get the best out of your C-leg, unlearning your old habits, and getting stronger is necessary.

Q: Who can receive GFS Outpatient Amputee Program Education?
If you have recently received a C-leg or have had one for some time and wish to get better function on it, have your family doctor refer you to the GF Strong Prosthetic Clinic and Outpatient Amputee Program.

Q: What about Stairs, Ramps, and Inclines?
If you have used a knee component that has no ‘stance phase flexion’ (hydraulic resistance while bending the knee), then learning to go down stairs and hills foot over foot using the C-leg can be very scary. This technique is sometimes called ‘riding your knee’. There is a training protocol used by physiotherapists to teach you to go down stairs foot over foot that will keep the fear to a minimum, improve your residual limb control and strength, and increase your confidence. This level of skill requires good balance, limb control, and confidence that comes with training over time. When your confidence and skill level is high, you should be able to go down either side of the stairwell, using one railing slightly, or not at all.

Q: What is involved in the Prosthetist Training?
Your C-knee comes with factory settings of the microprocessor that your prosthetist will adjust during your first visit. Typically these settings are set up for safety i.e. the resistance settings of your knee that allow you to sit down and stumble while walking, are high and thus safe. You should see your prosthetist over multiple visits to fine tune the settings as you improve your function. However no prosthetist will provide the level of specialized training that a physiotherapist will use based on a functional training protocol.

Q: What is involved in the Physiotherapist Training?
A physiotherapist who has attended the manufacturer’s education courses has the best knowledge of the intricacies of how the C-leg works. A physiotherapist who has trained amputees who have changed from an old knee to the C-leg has the best experience to teach you. Ask your prosthetist for a recommendation.

During training, your physiotherapist will contact your prosthetist and request that your microprocessor settings be updated for your improved level of walking ability and function.
