Simple Explanation

This study evaluates the safety and effectiveness of a new robotic exoskeleton called Atalante for people with complete spinal cord injuries. The Atalante system is designed to allow people with SCI to walk without needing crutches or other aids. Twelve patients with complete SCI participated in 12 one-hour training sessions over 3 weeks. They used the Atalante exoskeleton to walk on the floor while wearing a harness for safety. The study found that the Atalante system is safe and allows people with complete SCI to perform ambulatory functions like walking, standing up, and sitting down.

Study Duration
3 weeks
Participants
12 patients with complete SCI (AIS A)
Evidence Level
Prospective, open label, observational study

Key Findings

  • 1
    Seven out of eleven patients were able to walk 10 meters unassisted using the Atalante exoskeleton after 12 training sessions.
  • 2
    All patients were able to perform other ambulatory functions such as standing up, sitting down, maintaining balance, and turning.
  • 3
    The Atalante system increased patients' heart rate during walking, which may indicate that it helps retrain cardiovascular responses.

Research Summary

This study presents the first clinical results of the Atalante exoskeleton, a self-balancing walking system, for individuals with complete motor spinal cord injury (SCI). The study aimed to evaluate the safety and performance of Atalante in enabling ambulatory functions without technical aids. The study involved 12 patients with complete SCI who participated in a 3-week training program using Atalante. The primary outcome was the ability to walk 10 meters unassisted. The results showed that Atalante is safe and effective in enabling ambulatory functions in patients with complete SCI. Most patients were able to walk some distance unassisted, and many achieved the primary outcome of walking 10 meters unassisted.

Practical Implications

Improved mobility

The Atalante exoskeleton can provide individuals with complete SCI the ability to walk and perform other ambulatory functions, improving their mobility and independence.

Potential for cardiovascular benefits

The study suggests that using the Atalante system may help retrain cardiovascular responses, potentially improving cardiovascular health in individuals with SCI.

Future research directions

Further research is needed to explore the long-term effects of Atalante use, as well as its potential benefits for individuals with incomplete SCI or cervical SCI.

Study Limitations

  • 1
    Small sample size of patients
