Evaluation revealed a lack of sensation in her right foot, a dorsalis pedis pulse undetectable by Doppler ultrasound, and inability to dorsiflex
or plantarflex the right foot.
For example, have the child dorsiflex
against your hand, and push against it, then plantar flex and push down.
The difference between floor conditions relative to the ankle depends on how much more the ankle needs to dorsiflex
in order to accommodate the additional knee flexion that we observed in the trials in the hard floor condition.
The foot was unable to dorsiflex
or to clear the ground during the gait cycle.
Briefly, when a swelling is found in the Achilles tendon region, the subject is asked to dorsiflex
and plantar flex his ankle.
The child could actively dorsiflex
and evert the foot.
While the physiological ankle can actively dorsiflex
up to 27[degrees] during movement on stairs [1-2], prosthetic feet with solid ankle designs are fixed at 90[degrees] and those with articulated ankles and J-shaped ankle springs vary the amount of functional dorsiflexion based on their design.
Accordingly, participants were instructed to relax their hip but lock their knee and dorsiflex
The following signs were used to assess generalized joint laxity (GJL): passively dorsiflex
the 5th metacarpophalangeal joint to [greater than or equal to] 90[degrees], Oppose the thumb to the volar aspect of the ipisilateral forearm, hyperextend elbow to [greater than or equal to] 10[degrees], hyperextend knee to [greater than or equal to] 10[degrees], and place hands flat on the floor without bending the knees.
the fifth metacarpophalangeal joint to [greater than or equal to] 90[degrees] (Right/Left) 2.
As each target appeared, subjects were required to either dorsiflex
or plantarflex their paretic/dominant ankle to move a robot-controlled cursor up or down on a display screen to pass through targets *** (Figure 1(b)).
Furthermore, this dorsiflexed
prosthetic alignment is often necessary for improved standing stability in persons with bilateral transtibial amputations since they could not dorsiflex
their ankles if the GRF vector were to inadvertently shift posteriorly and throw them off balance.
