SUMMARY It was reported that about 10% of people suffer from painful knee arthritis, and a quarter of them were severely disabled. The core activities of daily living were severely limited by knee osteoarthritis (KOA). In order to reduce knee pain and prolong the life of the knee joint, there has been an increasing demand on the development of exoskeletons, for prevention and treatment. The course of KOA was closely related to the biomechanics of knee joint, and the pathogenesis was summarized based on the biomechanics of knee joint. For the prevention and clinical treatment, exoskeletons are classified into three categories: prevention, treatment, and rehabilitation after the operation. Furthermore, the design concepts, actuators, sensors, control strategies, and evaluation criteria were presented. Finally, the shortcomings and limitations were summarized. It is useful for researchers to develop suitable exoskeletons in the future.

In recent years, the burden for labor is increasing due to an aging society. To solve this issue, assistive suits are proposed as one of the solutions. In the previous study, an assistive suit has been developed that is based on variable viscoelasticity. However, the motion judgment interface for the variable viscoelastic based actuating device has not been studied. In this study, joint angle and joint angular velocity are used to judge the motion of the wearer, because variable viscoelastic based actuating device has a high backdrivability. In addition, with a suit of high backdrivability, the intention of a wearer can be shown as the joint angle. This study reports the motion judgment algorithm that is based on the wearer's joint angle, and joint angular velocity, and experiments have been conducted to evaluate the utility of the algorithm.

“…Many researchers made lower extremity exoskeleton for gait rehabilitation [8][9][10][11] with various types of actuators such as regenerative magnetorheological actuator, series elastic actuator, electric motor actuator, etc. Some devices even enhance lower extremity performance [12][13][14][15] to provide better mobility to patients with knee injuries or other kinds of loss of function in the lower extremities. For the arms, many types of assistive exoskeleton device have been described [16][17][18][19][20][21], and most devices can be combined with other adapted equipment.…”

For more than a decade, many countries have been actively developing robotic assistive devices to assist in the rehabilitation of individuals with limb disability to regain function in the extremities. The exoskeleton assistive device in this study has been designed primarily for hemiplegic stroke patients to aid in the extension of fingers to open up the palm to simulate the effects of rehabilitation. This exoskeleton was designed as an anterior-support type to achieve palmar extension and acts as a robotic assistive device for rehabilitation in bilateral upper limb task training. Testing results show that this wearable exoskeleton assistive device with human factor consideration using percentile dimensions can provide comfortable wear on patients as well as adequate torque to pull individual fingers into flexion towards the palm for rehabilitation. We hope this exoskeleton device can help stroke patients with loss of function in the upper extremities to resume motor activities in order to maintain activities of daily living.
