An Ankle-Foot Prosthesis Emulator Capable of Modulating Center of Pressure.

Summary of "An Ankle-Foot Prosthesis Emulator Capable of Modulating Center of Pressure."

Several powered ankle-foot prostheses have demonstrated moderate reductions in energy expenditure by restoring pushoff work in late stance or by assisting with balance. However, it is possible that center of pressure trajectory modulation could provide even further improvements in user performance. Here we describe the design of a prosthesis emulator with two torque-controlled forefoot digits and a torquecontrolled heel digit. Independent actuation of these three digits can modulate the origin and magnitude of the total ground reaction force vector.

Medical and Biotech [MESH] Definitions

Entrapment of the distal branches of the posterior TIBIAL NERVE (which divides into the medial plantar, lateral plantar, and calcanial nerves) in the tarsal tunnel, which lies posterior to the internal malleolus and beneath the retinaculum of the flexor muscles of the foot. Symptoms include ankle pain radiating into the foot which tends to be aggravated by walking. Examination may reveal Tinel's sign (radiating pain following nerve percussion) over the tibial nerve at the ankle, weakness and atrophy of the small foot muscles, or loss of sensation in the foot. (From Foot Ankle 1990;11(1):47-52)

The articulations extending from the ANKLE distally to the TOES. These include the ANKLE JOINT; TARSAL JOINTS; METATARSOPHALANGEAL JOINT; and TOE JOINT.

Deformity in which the foot is misaligned with respect to the TALUS in the ANKLE JOINT. While mostly congenital, as in CLUBFOOT, acquired deformities are included. Acquired talipedes are often associated with other foot deformities such as SYNDACTYLY and POLYDACTYLY.

The region of the lower limb between the FOOT and the LEG.

Harm or hurt to the ankle or ankle joint usually inflicted by an external source.
