Biomechanical comparison of two paraplegic gait patterns

Area of Science:

• Biomechanics
• Rehabilitation Science
• Orthopedics

Background:

• Paraplegia often necessitates assistive devices for ambulation.
• Common gait patterns include swing-to and swing-through using walking aids.
• Understanding the biomechanical differences is crucial for effective rehabilitation.

Purpose of the Study:

• To compare the kinetic and kinematic characteristics of swing-to versus swing-through gait in paraplegic individuals.
• To identify significant biomechanical differences influencing gait performance and upper limb joint loading.
• To inform clinical decisions regarding the selection and training of appropriate gait patterns.

Main Methods:

• Kinetic and kinematic data were collected from 14 individuals with spinal cord injuries.
• Subjects ambulated using two common gait patterns with walking aids.
• Analysis focused on gait velocity, axial load transmission, and joint impulse values.

Main Results:

• Significant differences were observed in gait velocity and axial load transmission between the two gaits.
• Load and moment impulse values were consistently higher for swing-to gait compared to swing-through gait.
• No clear differences in cumulative upper limb joint load transmission were found between the gait patterns.

Conclusions:

• Swing-through gait may impose lower biomechanical demands than swing-to gait for paraplegic individuals.
• Consideration of biomechanical factors is essential when selecting and training paraplegic gait patterns.
• Further research into gait optimization can improve functional mobility and reduce injury risk.
