Assessment of Gait Patterns during Crutch Assisted Gait through Spatial and Temporal Analysis

Area of Science:

• Biomechanics
• Rehabilitation Engineering
• Orthopedics

Background:

• Crutch ambulation is vital for lower limb injury recovery.
• Crutch gait patterns vary based on individual needs and injury type.
• Objective gait analysis can enhance clinical assessment and rehabilitation.

Purpose of the Study:

• To characterize four distinct crutch walking patterns.
• To assess the utility of instrumented crutches for gait analysis.
• To identify key spatial and temporal parameters for describing crutch gaits.

Main Methods:

• 27 healthy participants performed four different crutch gait patterns.
• A portable system integrated into crutches recorded force, position, and acceleration data.
• An algorithm segmented trials into gait cycles and phases for analysis.

Main Results:

• Significant differences were identified between the four crutch gait patterns.
• Spatial and temporal parameters effectively differentiated gait patterns.
• Instrumented crutches provided reliable data for gait analysis.

Conclusions:

• Instrumented crutches show potential as a clinical tool for monitoring assisted gait.
• Objective gait parameter analysis can improve diagnosis and treatment in rehabilitation.
• This technology facilitates personalized rehabilitation strategies for lower limb injuries.
