Using a hydraulic ankle device that provides dampened stance-phase passive articulation would allow the foot to passively dorsiflex during stance and thus enable the foot to leave the ground in a relatively dorsiflexed position and remain so throughout swing.
One might expect that because of reduced sensorimotor control of the prosthetic shank and foot, and the inability to dorsiflex the foot (to lift the "toes"), people with amputation would compensate and lift their prosthetic limb higher during swing through increasing hip and/or knee flexion.
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.
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.
Passively dorsiflex the fifth metacarpophalangeal joint to [greater than or equal to] 90[degrees] (Right/Left) 2.
The DF nerve also innervates the extensor hallucis longus and extensor digitorum longus muscles, which primarily extend the toes and dorsiflex the foot, predominantly in non-weight-bearing positions.
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)).
This was considered to be necessary because it is common for dancers to dorsiflex and simultaneously abduct the forefoot, giving the illusion of additional turnout.
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.
Third, I ask the dancer to dorsiflex the ankle several times as I move the talus with her so that we have an active and passive movement of dorsiflexion.
Exclusion criteria for control subjects were diabetes mellitus, hypertension, history of foot pain while at rest or leg pain during ambulation or exercise, lower-limb bypass surgery, absence of anterior or posterior tibial pulses, abnormal skin pressure/skin refill test (>2 s), smoking or drug use within the previous 6 months, dementia, and inability to plantar flex or dorsiflex ankles.
Plantar flexion is now passively maintained as the examiner uses his other hand to maximally dorsiflex the hallux (Fig.
