Background/objectives: As the use of rehabilitation exoskeletons (techniques) has become an important means of treatment of stroke patients. This study has discussed different actuator methodologies and techniques that can be used in a movement of the exoskeleton and proposed design of exoskeleton with enhanced efficiency. Methods/statistical analysis: After reviewing several actuation techniques and analyzing various products available in the market, a less complex easy functioning design of exoskeleton is proposed with improved performance and lifetime, which can able to detect the signal directly from the nerve system with the help of EMG sensors and command the actuator after processing of the signal for the required movement. Findings: Mainly there are two major contributors sensing and actuation technique that is responsible for the efficient working of the exoskeleton. There are such types of sensors available which can fetch data or signal directly from the nerve system of the human body. Tremendous work is going on to make the actuators less complex, handy and easy working in order to improve the quality of the exoskeleton. Again some of the conventional exoskeleton based on string and motor system is not appropriately performing. The electric linear actuation system is a better solution in order to make the exoskeleton more qualitative nowadays as compared to others. Improvements/ applications: Exoskeleton is helpful for the person with a disability in terms of movement and reduced their dependency on others. These devices are used to make a disabled person walking, running, jumping and do any other movementrelated work without any help.
