Abstract—spasticity is ponent of the upper motor At this stage, most Clinical doctors still used Ashworth
neuron syndrome, which also includes motor deficits and loss of Scale [2] to assess patient spasticity symptoms. At Ashworth
fine movement. Spasticity interferes with the patient’s natural
movement or patient’s remaining functional possibilities. After a
study on the ponent analysis (ICA), fast ICA test, patient remains in fortable sitting or supine by an
algorithm method is used to restore a clear-cut thigh experienced physician or physical therapist to the physical
electromyography (EMG) and angle curves which can carry out two-way movement in the stretch reflex and muscle tension
an accurate analysis of the spasticity. The algorithm has the assessed in Table 1 which is based mainly on assessment of a
virtue of simple principle, quick convergence speed and obvious patient's severity. Although this method which is simple to
de-noising effect. The results of theoretical analysis and clinical operate doesn’t need other medical equi
