Treadmill training offers the advantages of task-oriented training with numerous repetitions of a supervised gait pattern. It proved powerful in gait restoration of nonambulatory patients with chronic hemiparesis. Treadmill training could therefore become an adjunctive tool to regain walking ability in a shorter period of time.

The superiority of the MFES method as compared with conventional therapy was mainly attributed to the enhanced motor learning accomplished by application of MFES. These results, however, are preliminary, and further research is needed.

Twelve chronic hemiparetic outpatients with pronounced lower limb extensor spasticity were injected with 400 units of botulinum toxin A, EMG guided into the soleus, tibialis posterior, and both heads of the gastrocnemius muscles. Botulinum toxin A caused a definite reduction of plantar flexor spasticity, in 10 patients two weeks after the injection, as assessed by the Ashworth scale. Four of the patients were able to achieve active dorsiflexion of their affected ankle. Gait analysis including the measurement of vertical ground reaction forces showed a statistically significant (p < 0.01) improvement in velocity, stride length, stance symmetry, and the length of the force point of action under the affected foot. Qualitative improvements on the force diagrams indicated a better loading, advancement of the body, and push off of the affected limb in seven patients. Eight weeks after the injection the effects waned.

Multichannel electrical stimulation was applied in 20 patients with hemiplegia secondary to stroke or head injury using a six-channel microprocessor stimulator-stride analyzer to restore independent gait and to reestablish a normal gait pattern in a two- to three-week therapy period. The therapy was followed up at every session by a stride analyzer incorporated into the stimulator. At the beginning and at the end of the therapy period, each subject's gait was measured with a ground reaction measuring system. Statistical results and observations are presented for the group of 20 subjects, and a detailed description of the results is given for one subject who is representative of the whole group. According to the measured gait characteristics, gait improved significantly in all subjects during the therapy period, resulting in a partly or completely independent gait. The subjects' posture and endurance also improved, and they spontaneously learned how to use a crutch. The measurements and visual assessment of the subjects' progress indicate that the described treatment protocol offers good prospects for faster and more efficient gait rehabilitation in severely impaired patients. To determine the efficacy of gait therapy with multichannel electrical stimulation, a comparative study of conventional therapeutic methods and the method described in this article should be conducted.
