SmartIP
3 The SmartIP microprocessor controlled knee employs intelligent programming technology that dynamically programs the knee to optimum swing settings for the individual Level 3 activity user, reducing the amount of energy expended by trans-femoral prosthesis users. The weight activated stance control provides an adjustable smooth and yielding transition at toe off.
Key Features
- Smart Programming, electromechanical, adjustable terminal impact and extension damping
- Comfortable gait from very slow to very fast walking speeds
- Smoother speed progression because of enhanced program
- Weight activated stance control
- Stanceflex option improves comfort
- Battery life expectancy 9-12 months under normal usage
- 140° knee flexion
- 4-Bolt option reduces build height
SmartIP Clinical Evidence Reference
Improvements in Clinical Outcomes using prosthetic knees with microprocessor-controlled swing phase
- Less cognitive demand during walking, leading to reduced postural sway1
- Increased walking speed2-5
- Easier to walk at different speeds4,6
- More natural gait4
- Easier to walk on slopes4,6
- Reduced energy expenditure compared to (non-MPK) mechanical knees3-8
- Equivalent energy expenditure to other MPKs (swing and stance controlled)9
- Reduced self-perceived effort4,6
- Energy expenditure closer to that of able-bodied control subjects10
- Able to walk further before becoming tired4
- Better step length symmetry2,6
- Preference over other prosthetic knees4,6
