With an increase in number of knee problems in patients., the demand for the rehabilitation has increased. Most of the rehabilitation trainings are expensive and time consuming. So., the need for personalized treatment in rehabilitation is increasing. The knee exoskeleton is one of such solutions to assist the patients suffering from weal knee., paraplegia and hemiplegia. These exoskeletons meet the patient’s expectation in terms of assistance required and wearing comfort. These are relatively more portable than lower body exoskeletons owing to their lighter weight. These can either be used for gait rehabilitation., providing assistance during sit to stand motion., normal walking and running., for load carrying augmentation or for performing activities of daily living. In this work., a knee exoskeleton consisting of a linear actuator and surface Electromyography sensor is designed and fabricated. Experiments are performed to validate the results with those of theoretical one. The developed knee exoskeleton is found to be well suited for assisting the wearer during the rehabilitation.
