Defining spatial parameters for non-linear walking.

Area of Science:

• Biomechanics
• Human Locomotion
• Gait Analysis

Background:

• Traditional gait analysis relies on straight-line walking assumptions.
• Existing definitions fail to provide meaningful data for non-linear locomotion.
• Direction of progression (DoP) variability challenges current spatial and temporal gait parameter definitions.

Purpose of the Study:

• To present an alternative method for analyzing gait parameters during non-linear walking.
• To compare the results of the new method with traditional definitions.
• To assess the utility of the new method for understanding footstep adjustments and stability during turns.

Main Methods:

• Developed a novel method analyzing gait based on the changing direction of each stride.
• Compared spatial parameters of footstep patterns from linear and non-linear (60-degree turn) walking trials.
• Utilized output from both traditional and the new definitions for comparison.

Main Results:

• Traditional definitions yielded results heavily influenced by the change in direction.
• The new method, relative to changing stride direction, provided valuable insights into footstep adjustments.
• These adjustments were identified as crucial for enhancing stability during turning.

Conclusions:

• The proposed method offers a more meaningful analysis of spatial gait parameters during non-linear walking.
• This approach provides useful data on footstep adjustments for improved stability.
• The method serves as a valuable tool for future research in functional locomotion.
