Area of Science:

Biomechanics
Human Movement Analysis
Musculoskeletal Research

Background:

Non-invasive muscle force measurement during gait is a significant challenge in biomechanics.
Existing research explores the electromyography (EMG) and muscle force relationship.
Accurate muscle force data is crucial for understanding walking mechanisms and injury prevention.

Purpose of the Study:

To investigate the angle-EMG-force relationship in lower limb muscles.
To develop a method for estimating muscle force during gait using this relationship.

Main Methods:

Muscle force and EMG data were collected during a static muscle force measurement task.
The angle-EMG-force relationship was analyzed using the collected data.
This relationship was then applied to estimate muscle force during gait.

Main Results:

A significant angle-EMG-force relationship was identified for lower limb muscles.
The study demonstrated that muscle force during gait can be effectively estimated using this relationship.
This provides a novel approach for non-invasive muscle force analysis.

Conclusions:

The angle-EMG-force relationship offers a viable method for estimating muscle force during gait.
This contributes to a more accurate analysis of muscle function during walking.
The findings have implications for gait analysis, injury prevention, and rehabilitation.
