Flexor Digitorum Longus Tendon Transfer and Modified Kidner Technique in Posterior Tibial Tendon Dysfunction.

The modified Kidner procedure and flexor digitorum longus tendon transfer are common procedures used today when addressing posterior tibial tendon dysfunction. These techniques are often used in conjunction with a combination of osteotomies to correct flatfoot deformity, and have been proved to be reliable and predictable.

A proof-of-concept study for measuring gait speed, steadiness, and dynamic balance under various footwear conditions outside of the gait laboratory.

Background: This pilot study examined the effect of custom and prefabricated foot orthoses on self-selected walking speed, walking speed variability, and dynamic balance in the mediolateral direction.

Methods: The gait of four healthy participants was analyzed with a body-worn sensor system across a distance of at least 30 m outside of the gait laboratory. Participants walked at their habitual speed in four conditions: barefoot, regular shoes, prefabricated foot orthoses, and custom foot orthoses.
