OBJECTIVES: To investigate to what extent and with how much therapeutic effort nonambulatory stroke patients could train a gait-like movement on a newly developed, machine-supported gait trainer.
DESIGN: Open study comparing the movement on the gait trainer with assisted walking on the treadmill.
SETTING: Motion analysis laboratory of a rehabilitation centre.
SUBJECTS: Fourteen chronic, nonambulatory hemiparetic patients.
INTERVENTION: Complex gait analysis while training on the gait trainer and while walking on the treadmill.
MAIN OUTCOME MEASURES: Gait kinematics, kinesiological EMG of several lower limb muscles and the required assistance.
RESULTS: Patients could train a gait-like movement on the gait trainer, characterized kinematically by a perfect symmetry, larger hip extension during stance, less knee flexion and less ankle plantar flexion during swing as compared to treadmill walking (p <0.01). The pattern and amount of activation of relevant weight-bearing muscles was comparable with an even larger activation of the M. biceps femoris on the gait trainer (p <0.01). The tibialis anterior muscle of the nonaffected side, however, was less activated during swing (p <0.01). Two therapists assisted walking on the treadmill while only one therapist was necessary to help with weight shifting on the new device.
CONCLUSION: The newly developed gait trainer offered severely disabled hemiparetic subjects the possibility of training a gait-like, highly symmetrical movement with a favourable facilitation of relevant anti-gravity muscles. At the same time, the effort required of the therapists was reduced.
