Robot-assisted upper and lower limb rehabilitation after stroke: walking and arm/hand function

Area of Science:

• Neurorehabilitation
• Robotics in Medicine
• Clinical Trials

Background:

• Stroke survivors often require intensive motor rehabilitation for upper and lower limb recovery.
• Robotic devices offer potential for intensifying rehabilitation interventions.
• This article reviews controlled studies on robot-assisted stroke rehabilitation.

Purpose of the Study:

• To provide an overview of controlled studies on robot-assisted motor rehabilitation after stroke.
• To assess the effectiveness of different robotic systems in stroke recovery.

Main Methods:

• A systematic literature search was conducted for randomized controlled trials.
• Databases searched included Medline (PubMed), Embase, and CINHAL.
• Studies published between 1980 and 2007 were included.

Main Results:

• Electromechanical gait trainers showed significant benefits in promoting walking resumption compared to conventional physiotherapy.
• Exoskeleton-based systems yielded no consistent evidence of benefit.
• End-effector based systems and passive exoskeleton systems demonstrated effectiveness in arm/hand rehabilitation for stroke patients, particularly those with chronic symptoms.

Conclusions:

• Robot-assisted motor rehabilitation is a promising approach for stroke recovery.
• Further high-quality comparative trials are essential to validate efficacy.
• Robotic interventions should complement, not replace, the patient-therapist relationship.
