When we used a regression approach incorporating experimental values of both MTC and joint angles from people with TTAs wearing an active dorsiflexing
foot, we confirmed that MTC was sensitive to hip, knee, and ankle angle.
Another aid to diagnosis is the Babinski Sign which is carried out by stroking the soles of the feet, which results in the hallux dorsiflexing
, and the lesser toes spreading apart instead of the normal reflex action which would result in all five toes plantar flexing (11).
This decrease in Gastrocnemius muscle length change can be attributed to the increase in knee flexion during the flexed knee exercise, as a dorsiflexing
ankle coupled with a flexing knee will result in a smaller change in muscle length than with a fixed knee angle, as was the case in the extended knee exercise.
Prosthetic feet that can facilitate forward COM movement, by dorsiflexing
at the ankle either during the stance or swing phase of stair ascent, have the potential to promote work symmetry between limbs.
A physician starts by dorsiflexing
a patient's wrist from a neutral position, and then gently applies a massaging technique to stretch the flexor retinaculum (Siu, Jaffe, Rafique, & Weinik 2012).
The examiner guides the ankle into end-range dorsiflexion (the subject helps by actively dorsiflexing
Grasp the patient's heel and apply traction to it, dorsiflexing
