| Summary: | Research has shown that rehabilitation lower
limb exoskeletons (RLLEs) are effective tools for improving
recovery or regaining lower limb function. This device
interacts with the limbs of patients. Thus, actuators and
power transmission mechanisms are the key factors in
determining smooth human‒machine interaction and
comfort in physical therapy activities. A multitude of distinct
technologies have been proposed. However, we questioned
which consideration point in actuator selection and power
transmission mechanisms are used for RLLE. A review of the
technical characteristics and status of advanced RLLE
designs is discussed. We review actuator selection for RLLE
devices. Furthermore, the power transmission mechanisms
over the years within each of the RLLE devices are presented.
The development issues and possible research directions
related to actuators and power transmission mechanisms are
provided. Most RLLEs are still in the research phase, and
only a few have been commercialized. The aim of this paper
is to provide researchers with useful information for
investigating technological progress and highlight the latest
technological choices in RLLE development. |
