Learn more about our product
Impulse Technology has developed a 6 DOF ankle prosthesis that can be mounted on most commercially available prosthetic feet. The Goralign ankle “extends” the range of dynamic alignment performed by a prosthetist. In turn, there are significantly fewer negative effects of misalignment. Through mitigation of misalignment, our product enhances a patient’s mobility by adapting to changes in gait or terrain. The resulting effect of Goralign’s capabilities is a biomimicry of a natural ankle with sustainable comfort.
Our Product’s Features
- Passive Functionality – Goralign consists of a parallel series of spring and stiffeners without hydraulics, sensors, actuators, or electronics
- Three planes of motion (sagittal/coronal/transverse)
- Reduced socket movements
- Shock absorption during early stance
- Enhanced performance during turning
- Complete weatherproofing
Our Product’s Unique Value
- Current alignment processes require repeated prosthetist intervention. Our product significantly decreases clinical time and costs.
- Goralign’s features improve gait quality on uneven terrains, which significantly reduces the need for repeat patient visits for realignment.
- Upwards of 50% of amputees have mis-aligned prosthetics. Our product minimizes mis-alignment effects by self-aligning to gait or terrain changes.
Misalignment stemming from other products can lead to the following issues:
- Associated pain
- Labored and abnormal walking style
- Decreased mobility
- Robotic prostheses featuring micro-processors are overly complex and expensive (some could cost more than $15,000!)
