Simple Explanation

This case report explores whether someone with a C4 spinal cord injury, impacting hand function, can use a powered exoskeleton effectively. The study looks at whether the exoskeleton can improve physical activity, measured by walking time and steps taken. A 21-year-old male with a C4 spinal cord injury participated in exoskeleton training sessions over two weeks, and his progress was tracked.

Study Duration
2 weeks
Participants
A 21-year-old male with incomplete chronic (>1 year postinjury) SCI C4
Evidence Level
Level 4; Case Report

Key Findings

  • 1
    The participant's maximum walk-time increased from 7 to 17 minutes over the 2 week study period.
  • 2
    The number of steps taken during training increased from 83 to 589 steps.
  • 3
    The total up-time (time spent standing) increased from 19 to 31 minutes.

Research Summary

This case report investigates the feasibility of using a powered exoskeleton for ambulation in an individual with C4 incomplete SCI and limited hand function. The participant, a 21-year-old male, underwent three training sessions and showed improvements in walk-time, up-time, and number of steps. The study suggests that exoskeleton training may be a safe and feasible approach for individuals with high-level SCI, providing a supportive device for weight shifting.

Practical Implications

Rehabilitation Potential

Exoskeleton training can be considered for individuals with high-level tetraplegia (C4 and above) and limited hand functions.

Assistive Device Design

The use of platform walkers and hand cuffs can enable individuals with limited hand function to use exoskeletons effectively.

Future Research

Future studies should include individuals with higher-level injuries in exoskeleton training programs, provided appropriate screening and support are available.

Study Limitations

  • 1
    Single case study limits generalizability
  • 2
    Short study duration (2 weeks)
  • 3
    Lack of a control group
