| Summary: | In response to the increasing number of patients with lower limb dysfunction caused by stroke and other diseases, and the low penetration rate of gait rehabilitation robots caused by the expensive cost and difficult operation of most current device, this study proposes a novel gait rehabilitation device with a single actuator. A gait simulation mechanism is designed based on the single-degree-of-freedom six-bar Klann’s mechanism. This mechanism can generate the ankle trajectory of human gait. As this is a nonanthropomorphic design, it does not need to be aligned with patient’s joints, which facilitates the donning and doffing of the device and avoids discomfort to the patient caused by misalignment. The mechanism is adjustable so that it can provide a fit for different patients. In addition, a novel pneumatic body weight support apparatus is also designed which supports partial body weight of patient. This apparatus can help patients with lower-limb muscle strength deficit carry out the gait rehabilitation training consciously. The proposed gait rehabilitation device can move according to the walking pace of the training, which makes the rehabilitation training more interesting and assists the patients to complete some daily life activities. A prototype is manufactured and conducted a study with a subject. Due to its low cost, small size, ease of operation, the proposed system potentially offers a novel device for body weight supported gait rehabilitation training. |
