Does crutch length influence gait parameters after total hip replacement surgery?

Area of Science:

• Orthopedics
• Biomechanics
• Rehabilitation

Background:

• Crutches are essential for mobility after total hip replacement.
• Optimizing crutch use can enhance patient recovery and gait quality.

Purpose of the Study:

• To investigate how different crutch setups (elbow flexed vs. elbow extended) affect gait performance and symmetry.
• To analyze the influence of crutch setup on spatiotemporal and kinetic gait parameters.

Main Methods:

• Thirty patients were randomized into elbow flexed (EF) or elbow extended (EE) crutch groups.
• Gait analysis was performed using motion tracking and force platforms.
• Spatiotemporal parameters, ground reaction forces (GRF), and limb symmetry were evaluated.

Main Results:

• The EF group exhibited decreased stride length and increased base of support width compared to the EE group.
• Operated limb GRF decreased in the EF group, while crutch force decreased in the EE group.
• The EF group showed greater stride length variability and asymmetry in force and spatiotemporal parameters.

Conclusions:

• Elbow extended (EE) crutch setup is superior to elbow flexed (EF) setup for post-total hip replacement patients.
• EE setup promotes better load-bearing on the operated limb and reduces crutch load and gait asymmetry.
• Clinicians should consider EE setup for optimizing patient rehabilitation and gait parameters.
