Active knee extension (a) did not result in full extension, whereas extension with single-joint hybrid assistive limb assistance resulted in full knee extension
The designed knee ergometer which allows the utilization of the voluntary non-paretic movement had reduced the required stimulation to perform repetitive full knee extension
of the paretic leg.
They made a suggestion that ROM in ankle dorsiflexion was limited in full knee extension
in supine position that caused difficulty in dorsiflexion.
To ensure full range of motion was obtained for each repetition, the distal portion of the shin (tibia) had to contact a piece of nylon tape that was positioned at a height equal to full knee extension
She had full knee extension
and was capable of flexion to 130[degrees].
There was minimally painful medial knee joint opening at 25 degrees flexion with valgus stress test but there was no laxity at full knee extension
The design goal was to maximize the locking torque of the SCKM at/near full knee extension
by optimizing the moment arm as a function of knee angle while minimizing the torque that is required to drive the knee during the swing phase of gait when the mechanism is unlocked.
During open chain exercises, the amount of quadriceps muscle force required to extend the knee progressively increases as the knee moves from 90 to full knee extension
Each turn cycle was defined as two consequent values of minimum knee flexion so that each cycle was composed of one left turn plus the sequential halves of the two associated right turns (Figure 2); 180[degrees] was considered full knee extension
The start position was set at 70[degrees] to 75[degrees] of knee flexion and the end position at 5[degrees] to 40[degrees] of knee flexion, a position that corresponded approximately to full knee extension
for each subject.
Since full knee extension
is required to engage the knee lock, the knee will be unsupported if flexed during limb loading.
