The ankle joint
was dorsiflexed at 5[degrees]/s starting from 30[degrees] of plantar flexion, until the passive resistive torque corresponding to 20% of the pre-measured maximal voluntary plantar flexion torque was reached.
These muscles were selected due to their established role in regulating static and dynamic postural stability about the ankle joint
By comparing a variety of ankle rehabilitation robots, it was found that an optimal robotic design for comprehensive ankle rehabilitation should be characterized with appropriate workspace and actuation torque, aligned rotation center between the robot and the ankle joint
, and adjustable robot posture.
However, in this osteosarcoma case report, it was not a total tibia replacement as no total ankle joint
replacement was made, since part of the distal tibia was not removed.
Additionally, the large number of ligamentous structures and overall strength of the ligaments provide significant supplemental stability to the ankle joint
After the reduction of the dorsiflexion of the ankle joint
, the flexion in the knee joints decreased, and the positive and the negative powers both decreased (Figures 9 and 11).
(10) In this case, ankle instability, major concern in these fractures should be the restoration of the stability of the ankle joint
by repair of the ligamentous elements.
To evaluate the mechanical properties of the ankle joint
, the ankle dorsiflexion angle and ankle joint
passive torque were measured sequentially, and the muscle-tendon complex stiffness was calculated from these parameters.
Left ankle angle: the left ankle joint
is the peak, the heel of the left foot and left knee joint respectively forms two lines with the left ankle joint
These injuries are of utmost importance as the ankle transmits the whole body weight and the stability of ankle joint
determines the locomotion.
To evaluate active and passive ankle joint
position senses, 10[degrees] and 20[degrees] of ankle inversion and 15[degrees] and 30[degrees] of ankle plantarflexion were selected as the test angles.
Their ankle joint
, however, allows only the updown motion of the foot.
