"They imagined a shoe where benchmark responsiveness and lightweight stability were not separate entities, but were seamlessly integrated, transforming the way the foot moved through the
gait cycle. The Kinvara continues to represent our innovative and product philosophy across the brand, focusing on every aspect of the runner's stride."
After receiving the prosthetic knee, the device is tuned to tweak 12 different control parameters to accommodate the specific patient and address prosthesis dynamics such as joint stiffness throughout the entire
gait cycle.
The first mechanism of injury occurs following a forceful eccentric contraction at a high speed, during the late swing phase of the running
gait cycle. The second mechanism of injury occurs when the hamstring muscle is stretched beyond its available range of motion or load tolerance.
Make sure you're fitted properly into your shoe by a member of staff who's trained on the various technologies in each style and the intricacies of the
gait cycle.
The
gait cycle begins with the hip of the amputated limb (figure 7), with a value close to the maximum extension and the knee at 12[degrees] of flexion; the curve decreases slowly until reaching the point of mid-stance, where the knee reaches 8[degrees] of flexion while the hip is at approximately 5[degrees] of extension.
For the purposes of this torque control, the
gait cycle was divided into two phases: stance and swing (Figure 5).
A pressure sensitive sensor ('foot switch') was attached to the sole of the participants heel to record the instant of heel contact, which allows the identification of the
gait cycle (heel contact to ipsilateral heel contact).

gait cycle timing in Parkinson's disease and Huntington's disease," Movement Disorders, vol.
The two surface electrodes of each channel were placed on the motor points to stimulate the tibialis anterior, quadriceps, hamstrings, and gastrocnemius of the hemiplegic leg in the sequence of the
gait cycle. The two-channel group had the tibialis anterior and the peroneus longus and brevis stimulated to facilitate ankle dorsiflexion and eversion in sequence.
[5] found that the ability to maintain a steady gait, with low stride-to-stride variability of
gait cycle timing and its sub-phases, was diminished for both PD and HD, two typical disorders of basal ganglia.
calculated muscle forces in full
gait cycle by inverse dynamic analysis.
