Three-dimensional human gait pattern - reference data for normal men.

Area of Science:

• Biomechanics
• Human Movement Analysis
• Kinesiology

Background:

• Establishing normative gait patterns is crucial for motion analysis systems.
• Understanding kinematic variations across different gait speeds is essential for accurate biomechanical assessments.
• The BTS Smart-E system is utilized for detailed gait analysis.

Purpose of the Study:

• To establish a kinematic pattern of adult gait for the BTS Smart-E motion analysis system.
• To analyze gait patterns across three distinct speed levels: high, preferred, and low.
• To investigate the influence of gait speed on joint kinematics in adult males.

Main Methods:

• Gait analysis was performed on 17 adult males using the BTS Smart-E motion analysis system.
• Kinematic data were collected for three controlled walking speeds.
• Statistical analysis was employed to compare joint motion across different speeds and between limbs.

Main Results:

• No statistically significant differences were found between the right and left limbs' gait patterns.
• Significant differences in gait patterns were observed across high, preferred, and low walking speeds.
• Increased gait speed correlated with changes in the angular range of motion in the hip and knee joints' sagittal plane.
• Joint range of motion generally increased with higher walking speeds, except for the ankle joint.

Conclusions:

• Gait speed is a critical factor influencing adult kinematic gait patterns, particularly in the hip and knee joints.
• The BTS Smart-E system can effectively capture speed-dependent kinematic variations in gait.
• Further research may explore normative data across diverse populations and conditions.
