Comparison Between Robotic and Conventional Walking Recovery Training Methods in People With Spinal Cord Injury:...

Area of Science:

• Neurorehabilitation
• Robotics in Medicine
• Spinal Cord Injury Research

Background:

• Spinal Cord Injury (SCI) significantly impairs gait and cardiovascular function.
• Robotic interventions like RBWSTT and ORET offer potential for recovery.
• Optimal timing and type of robotic training for SCI remain under investigation.

Purpose of the Study:

• To compare Robotic Body Weight Supported Treadmill Training (RBWSTT), Overground Robotic Exoskeleton Training (ORET), and Conventional Physiotherapy (CP) for gait and cardiovascular outcomes in SCI.
• To stratify comparisons by injury level, severity, and onset (subacute vs. chronic).

Main Methods:

• Systematic review and network meta-analysis of 25 randomized controlled trials (RCTs) involving 905 participants.
• Searches conducted across major databases (MedLine, CENTRAL, Scopus, Web of Science) until May 2025.
• Risk of bias assessed using the Cochrane RoB2 tool; data synthesized via meta-analysis.

Main Results:

• In subacute SCI, RBWSTT significantly improved 6-Minute Walking Test, Lower Extremity Motor Score, and Walking Index for Spinal Cord Injury II compared to CP.
• In chronic SCI, ORET demonstrated improvements in Lower Extremity Motor Score and aerobic efficiency.
• RBWSTT exhibited better tolerability; overall evidence quality ranged from very low to moderate.

Conclusions:

• RBWSTT appears more effective for gait recovery in subacute SCI.
• ORET may offer benefits for chronic SCI patients, particularly in motor function and aerobic capacity.
• Findings support personalized robotic rehabilitation strategies for SCI, emphasizing the need for higher-quality evidence on long-term effects.
