The C-Brace is an advanced orthotic device that supports walking by recognizing and responding to the user's movements and surrounding environment in real time. Its primary goal is to enable users to walk safely and naturally. Beyond simply walking on flat ground, the C-Brace allows users to navigate uneven terrain, go up and down slopes, and descend stairs one step at a time. With the C-Brace, users can hold their child in one arm, enjoy a fragrant cup of coffee while taking in the scenery, or have a conversation with someone beside them?without having to constantly focus on their orthosis or watch the ground. It also prevents users from collapsing into a chair when sitting down and makes climbing stairs or slopes easier, ultimately expanding their range of movement. As a result, it enhances convenience in various environments and allows users to explore more places and enjoy a broader, more independent life.
