limbbased

limbbased is a term used in technical and descriptive contexts to denote systems, methods, or organisms that rely primarily on limbs for locomotion, manipulation, or control. The concept is not tied to a single discipline, but rather to the central role that limbs play in the function being described. As such, limbbased can apply to biology, robotics, prosthetics, and human–computer interaction.

In biology, limbbased movement refers to locomotion or manipulation driven by limbs, such as legged gait in tetrapods or arm-assisted handling of objects. This contrasts with fin-based, wing-based, or limbless forms of movement. The term is often used descriptively to categorize organisms or to discuss biomechanics and motor control.

In robotics and prosthetics, limbbased describes devices and control schemes that are activated or guided by limb motion. Examples include powered prostheses that respond to residual limb signals, exoskeletons that augment leg or arm movement, and motion-controlled interfaces that use arm or leg movements as input. Control strategies may incorporate sensors detecting muscle activity, motion, or position to translate limb movement into device commands.

In rehabilitation and therapy, limbbased approaches emphasize restoring or improving function through limb-centered exercises and tasks, aiming to recover coordination and strength in the limbs.

Limitations of limbbased approaches can include constraints on range of motion, energy efficiency, user comfort, and the cognitive load of controlling complex limb movements. The term remains a broad descriptor rather than a formal taxonomy, used where limb-centric analysis or design is intended.
