The selection of Product Types for lower limb assistance is diverse, ranging from full-body powered suits to joint-targeting devices. Full-body exoskeletons, such as ReWalk and Ekso, support the hips, knees, and ankles, enabling paralyzed individuals to stand and walk. These are classified as weight-bearing devices and are instrumental in both rehabilitation (gait training) and personal assistance.

An alternative product approach focuses on joint-targeting devices, which concentrate assistance torque on a single joint, such as the ankle or knee. These systems are typically employed for patients recovering from stroke or those with conditions like multiple sclerosis, where the goal is to correct asymmetric gait patterns or improve motor coordination. Whether full-body or joint-targeting, nearly all modern lower-limb systems utilize built-in sensors and proprietary algorithms to classify the user's locomotion intention—such as walking, standing up, or climbing stairs—and deliver the appropriate, energy-efficient assistance.
