Moving arm is the world’s first home mobility platform that unfolds the contracted body. We developed the world’s first Multi Axis Armrest Stretching technology. Unlike conventional massage approaches that rely on compression, this technology expands the body by extending the arms and shoulders along their natural joint trajectories. It opens contracted muscles and stiff joints, restoring mobility through expansion rather than pressure. This is not static stretching or passive traction. Instead, it is a robotic implementation of human joint kinematics, reproducing the actual movement paths of the shoulder joints to unfold the contracted body and help users regain lost mobility.
