dorsiflex การใช้

Drop Foot is the inability to dorsiflex, evert, or invert the foot.
The gastrocnemius and soleus modulate the tibialis anterior to dorsiflex the foot, and finally the intrinsic and extrinsic foot muscles are active.
The foot is adducted and plantar-flexed at the subtalar joint, and the goal is to abduct the foot and dorsiflex it.
Liberson et al ., 1961 was the first to observe that some stroke patients appeared to benefit from a temporary improvement in function and were able to dorsiflex their foot for up to an hour after the electrical stimulation had been turned off.
Case in point : when the muscles which dorsiflex ( flex the foot upward ) are less functional than the muscles which plantarflex ( flex the foot downward ) a contracture occurs, giving the foot a progressively downward angle and loss of flexibility.
