Background:

Chronic stroke often results in upper extremity hemiparesis, limiting functional independence.
Conventional therapies may not fully restore arm function in stroke survivors.
Need for personalized and adaptive rehabilitation strategies to address varying patient needs.

Purpose of the Study:

To investigate a novel robotic therapy for upper extremity rehabilitation in chronic stroke patients.
To test the hypothesis that guided force training improves functional arm ability.
To develop and evaluate an adaptive algorithm for personalized robotic assistance.

Main Methods:

Development of a guided force training task using the ARM Guide robotic device.
Implementation of an adaptive algorithm to modulate velocity-dependent assistance based on movement speed.
A single-participant, two-month training program with the adaptive robotic system.

Main Results:

The participant demonstrated significant improvements in functional task performance after the training period.
The adaptive algorithm successfully tailored assistance based on the individual's movement capabilities.
The guided force training approach showed potential for superior outcomes compared to conventional methods.

Conclusions:

Adaptive robotic therapy, utilizing guided force training, offers a promising approach for upper extremity recovery post-stroke.
The developed adaptive algorithm effectively personalizes rehabilitation, accommodating diverse patient abilities.
This novel robotic intervention shows potential to enhance functional gains in chronic stroke survivors.
