Gaitscan / Force Plate Evaluation

A force plate, such as the Gaitscan system, is a valuable tool used in biomechanical analysis to evaluate how forces are transmitted through your foot during walking or running. It provides insights into how your foot interacts with the ground, distributes forces, and plays a crucial role in shock absorption, foot rigidity, and the windlass effect for optimal movement. Here’s a description of how a force plate, like Gaitscan, is utilized as a part of your assessment:

1. Force Distribution:

A force plate is embedded within a walkway or treadmill, and it contains multiple sensors that measure the vertical forces exerted by the foot as it contacts the ground during walking or running.
As a person walks or runs over the force plate, it captures data on the magnitude, timing, and distribution of forces applied by different regions of the foot.

2. Shock Absorption:

By analyzing the force data, the Gaitscan system can assess how effectively the foot absorbs shock during impact with the ground. This information is critical for identifying potential issues related to cushioning and shock absorption.
Poor shock absorption can lead to discomfort, fatigue, and increased risk of injuries like stress fractures.

3. Foot Rigidity:

Foot rigidity refers to the ability of the foot to adapt to varying terrain and provide support during different phases of the gait cycle.
The force plate helps evaluate foot rigidity by assessing how forces are transmitted through the foot’s arch and whether it maintains its structural integrity during weight-bearing activities.

4. Windlass Effect:

The windlass effect is a biomechanical phenomenon related to the plantar fascia, a band of connective tissue on the sole of the foot.
As the toes are extended during the push-off phase of walking or running, the plantar fascia becomes taut, creating a rigid lever that enhances propulsion.
Gaitscan can analyze the timing and magnitude of forces under the foot, providing insight into how well the windlass effect is functioning.

5. Pressure Mapping:

In addition to measuring vertical forces, Gaitscan often includes pressure sensors that create pressure maps of the foot during each step.
These pressure maps show areas of high and low pressure, helping identify pressure points, abnormal weight distribution, or imbalances in the foot that may contribute to gait abnormalities or discomfort.

6. Visual Gait Analysis:

Gaitscan typically integrates with a computer system that displays a visual representation of the gait cycle.
This visual feedback allows clinicians and researchers to identify irregularities, abnormalities, and deviations in a person’s gait pattern, helping diagnose and address specific issues.

7. Custom Orthotic Design:

The data collected from Gaitscan can be used to design custom orthotic insoles tailored to an individual’s specific gait and biomechanical needs.
These orthotics can help correct imbalances, improve shock absorption, and optimize the windlass effect, leading to more efficient and comfortable movement.

The Gaitscan force plate system is a powerful tool for assessing how forces are transmitted through the foot, evaluating shock absorption, foot rigidity, and the windlass effect. This information is essential for diagnosing gait abnormalities, designing custom orthotics or rehabilitation programs, and optimizing your movement patterns for better overall foot health and performance.
