JNER: A randomized clinical controlled study on the efficacy of three-dimensional upper limb robotic exoskeleton training on chronic stroke

Upper extremity dyskinesia is one of the most common causes of long-term disability after stroke and is particularly problematic given its negative impact on activities of daily living (ADL)
.

Physical therapy and exercise promote motor recovery after stroke, thereby restoring function and altering cortical reorganization according to residual neuroplasticity

While robotic-assisted rehabilitation has been shown to be effective for stroke rehabilitation, there has been limited functional improvement in activities of daily living following robotic training
.

To achieve this goal, in this study, we compared the efficacy of robotic training using a multi-joint functional exoskeleton in goal-directed training with conventional physical therapy regimens in terms of clinical and functional outcomes, both in terms of intensity and time the same

Research Process

L-EXOS is a tendon-driven robotic exoskeleton characterized by a series of kinematics consisting of five rotational joints, the first four of which are actuated : the first three rotational axes are kinematically orthogonal to each other (two by two) to simulate the kinematics of a spherical joint with the same center of rotation of the human shoulder, assuming the fourth axis coincides with the elbow joint and the fifth axis coincides with the forearm (perceived only) to allow for wrist pronation supinate
.

The L-EXOS features a remotely placed motor, and by using tendon transmission, torque can be easily transferred to a joint away from the motor, drastically reducing inertia during free motion, with zero backlash, low friction, and low weight

The execution time (measured by the functional BAT scale) when performing the ADL task was significantly improved in the RG group compared to the CG group on both gross and fine motor tasks
.

The observed differences between the two groups were only reflected in the temporal execution of the BAT scale, not in quality, and could be explained by two reasons: (1) the measurement of quantitative parameters (such as time) in detecting changes in task execution Aspects are more precise than qualitative parameters (2) The improvement in ADL performance may not necessarily be due to an overall improvement in exercise quality, and in addition, the adoption of compensatory exercise strategies may also play a role in functional recovery
