Proximal medial longitudinal arch incision for plantar fascia release.

A curved, oblique plantar incision in the proximal aspect in the medial longitudinal arch was used to release the plantar fascia in eight feet with recalcitrant plantar fasciitis. Seven feet became pain free and the eighth was 75% improved. Normal sensation to the heel was preserved in all cases.

A system to measure the forces and moments at the knee and hip during level walking.

The forces and moments in the sagittal plane at the knee and hip were calculated using gait data collected during level walking. Accelerations were measured by accelerometers attached to the legs, and the force reactions at the foot were measured by a force plate. The recorded accelerations and the foot forces were used to determine the joint reactions through a Newtonian formulation modeling the leg as articulated, rigid links.

Afferent sensory feedback for lower extremity prosthesis.

Electrical stimulation has been applied to sciatic nerves of patients to achieve sensory feedback after lower limb amputation for periods of up to six years. Patients used the sensory feedback device daily. Pain, infection and electrode displacement have not been problems.
