Meet the Caplex PRO Ankle Prostheses

Our prosthetic ankle devices interface with the body using industry-standard pyramid adapters, suitable for persons with below-knee amputation or with Humotech simulator boots, and provide robotically-controlled keel/forefoot behavior. They feature adjustable heel stiffness as well as adjustable forefoot length and device mass. Suitable for use in laboratories studying emulation test-drive paradigms, developing robotic control strategies, and more.

PRO-004 - Pylon Emulator

The PRO-004 is a single degree-of-freedom tethered robotic pylon capable of exhibiting a wide range of programmable axial stiffness behaviors. It can be used to design and evaluate custom designs or to emulate the function of commercially-available shock-absorbing pylons. PRO-004 features standard prosthetic pyramid adapters and can be paired with Caplex PRO ankle-foot prostheses or commercially-available prosthetic feet. PRO-004 is suitable for prosthetic foot users, either people with amputation or people without amputation using a bent-knee adapter.

PRO-003 Modular Ankle Foot Prosthesis with Multi-Axial Actuation

The PRO-003 is a tethered prosthetic foot appropriate for walking on a level, inclined, or cross-sloped treadmill, uneven treadmill, or stairmill for users weighing up to 263 lbs. Plantar/dorsi-flexion torque as well as inversion/eversion torque is controlled by our off-board Full-Sized Actuator Units (Single-Axis or Multi-Axis) and Control System. Sensors include load cells for torque applied by—and an encoder for rotational position of—the forefoot segments. It can accommodate a range of user foot sizes (approximately shoe sizes 26cm to 29cm).

PRO-002 Modular Ankle-Foot Prosthesis

The PRO-002 is a tethered prosthetic foot appropriate for walking on a level or inclined treadmill, or stairmill for users weighing up to 250 lbs. Plantar/dorsi-flexion torque is controlled by our off-board Full-Sized Actuator Units (Single-Axis or Multi-Axis) and Control System. Sensors include a load cell for torque applied by—and an encoder for rotational position of—the forefoot segment. It can accommodate a range of user foot sizes (approximately shoe sizes 26cm to 29cm).

PRO-001 Ankle-Foot Prosthesis (Legacy)

Our legacy PRO-001 is a tethered prosthetic foot appropriate for walking on a level or inclined treadmill, or stairmill for users weighing up to 250 lbs. Plantar/dorsi-flexion torque is controlled by our off-board Full-Sized Actuator Units (Single-Axis or Multi-Axis) and Control System. Sensors include a load cell for torque applied by—and an encoder for rotational position of—the forefoot segment. It is designed for an average US male foot size.
