Spasticity, which is the major cause of decreased balance and
gait, has commonly been reported in patients with stroke,
multiple sclerosis, spinal cord injury, and traumatic brain injury.
Moreover, spasticity causes spastic movement disorder,
slowed gait, and disturbances in voluntary movement [4]. In
addition, passive and active range of motion, functional ability,
and dynamic balance are affected [5]. Passive movement
[6], passive stretching [7], prostheses [8], and electrical stimulation
[1] have been employed in efforts to decrease spasticity
