The ability of a prosthetic foot to
dorsiflex during stance or swing phase and hence allow forward movement of COM appears to be a major contributor to interlimb kinetic symmetry.
Then, the ankle joint was passively
dorsiflexed until it reached 10[degrees] of dorsiflexion, then rested for 10 seconds.
Hip hiking during the prosthetic swing phase is often observed in persons with unilateral transtibial or transfemoral amputations and is believed to be a compensatory motion that increases prosthetic foot clearance because of the inability to
dorsiflex the prosthetic ankle [13].
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.
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.
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.
Plantar flexion is now passively maintained as the examiner uses his other hand to maximally
dorsiflex the hallux (Fig.
The participants in our study were instructed to
dorsiflex their ankle joint to avoid the excessive external rotation of the tibia and to establish a better alignment, keeping the tibial tuberosity medial.
Force control insufficiency in the tibialis anterior muscle (TA), such as weakness, delayed or decreased recruitment, and reduced motor cortical control, is characterized by an inability to adequately
dorsiflex the ankle during functional tasks such as moving from sitting to standing, stand-pivot-sit transfer, standing with balance perturbation, curb or stair climbing, and walking [3-9].
The subject was then asked to
dorsiflex the ankle as fast as possible every 10 s (to 50% of [MVC.sub.DF] to avoid fatigue) following an auditory cue (see Figure 1).
The patient was asked to actively
dorsiflex and plantar flex the ankle from a starting position with the foot relaxed (considered the zero neutral position) with angle measurements taken at each point of dorsiflexion and plantar flexion.
Although it does not insert into the proximal phalanx, it is able to
dorsiflex the proximal phalanx of the MTP joint through this aponeurotic band, which goes around the MTP joint and is inserted onto the plantar plate.
