Methods for interpreting gait analysis data

There is still not an accepted general theory of why we walk the way we do. In the absence of this, many explanations of walking address the mechanisms by which specific movements are achieved by particular muscles. A whole new methodology is developing to determine the functions of individual muscles. This needs further development and validation. A particular requirement is for subject specific models incorporating 3-dimensional imaging data of the musculo-skeletal anatomy with kinematic and kinetic data.

Smart Shoe Design: Adaptable Shoe for Foot Pronation

The final design of the “Smart Shoe” can be broken down into two main components: the data collection and processing system, and the control of the shoes variable stiffness. The force distribution of a user’s foot will be measured using force-sensing resistor (FSR) sensors, while a Arduino Mega and a custom printed circuit board (PCB) collect and process the force data. Ten FSR sensors are distributed along the insole and communicate with a MATLAB program via Bluetooth. When certain force thresholds are exceeded, the software attempts to vary the stiffness of the insole in order to adjust the forces to an acceptable level. The software does this by triggering solenoid valves and an air compressor to control air-flow inside the shoe that will modify its stiffness. An HC-05 chip is used to transfer the sensor readings via bluetooth to the MATLAB program.

New Gait Analysis Device /System

Portable Gait Analysis

The value of sophisticated, video-based gait analysis is well established.

However, the cost of establishing a gait analysis clinic is high (often more than $250,000). A gait lab also requires space and dedicated personnel. As a result, routine use of gait analysis in clinics has been very limited.

In addition, the lab environment under observation does not mirror the patient’s actual living or mobility requirements. That is, labs analyze a very limited number of steps on level ground.

A Revolutionary New Gait Analysis Device

The need for an easy to use, inexpensive, yet accurate and portable gait analysis system has been too long. However, highly dedicated research in both medicine and technology is a must before this can happen.

Gait analysis seeks to identify the root of an injury, or a bad habit that may lead to one. It usually starts with an evaluation of strength and flexibility that includes some manipulation on an examination table and a series of exercises. A running session on a treadmill in front of a video camera follows.

Development of Plantar Pressure Measurement System Using Triaxial Force Sensor

QQ截图20151214090514.jpg

The bottom of a person’s foot grips the floor for balance, and the action force and action moment work at the foot bottom when he maintains posture and when he moves. They are important indices in the evaluation and the medical attentions of standing pose balance and gait disturbances. A lot of equipment to measure the floor reaction force have been researched. However, no floor reaction force meter exists that can measure distribution information force in three directions. This paper aims at the development of a system that can measure the planter pressure that exists from a measurement instrument and that can measure the planter pressure distributed 6 × 4 three axis force sensors and software that displays and preserves the output of the sensor element. A time change of force that worked at the foot bottom is sought as a vector by outputting each sensor element. Moreover, an action vector is three dimensionally displayed whose data can be intuitively understood. The results of experiments show that the measurement system can measure the action force of the foot bottom as distribution information on force in three directions.

The impressive FootLogger technology provides a new set of data that wristband-style activity trackers do not, which can be applied in a wide variety of ways depending on what field you are in. For healthcare professionals, the smart insoles provide a bevy of information involving the alignment of the spine, while high-performance athletes can figure out if they are placing and transferring their weight correctly.
