Gait freezing, also called motor blocks, is a manifestation of akinesia.[1] Gait freezing is characterized by a sudden inability to move the lower extremities which usually lasts less than 10 seconds.[1] It may worsen in tight, cluttered spaces, when attempting to initiate gait or turning around, or when approaching a destination.[1] Freezing improves with treatment and also with behavioral techniques such as marching to command or following a given rhythm.[1] Dystonia[1] is abnormal, sustained, sometimes painful twisting muscle contractions, often affecting the foot and ankle (mainly toe flexion and foot inversion), which often interferes with gait.
