The FIT Shoe by Davina for Next

February 8th, 2012 | Biomechanics Consultancy, Podiatry, Quintic Video Software, RSscan - Footscan

In autumn 2011 Quintic conducted a biomechanical gait analysis of the new FIT Shoe Range by Next. There are currently 5 styles of shoe in the Davina FIT range: the trainer, the pump, the ballerina, the wedge and the flat workwear shoe… with the pointed shoe and the sandal soon to be added.

The study, which used females who met the proposed target market for the Davina FIT shoe, compared each style of FIT Shoe to a typical equivalent shoe, as well as barefoot. An RSscan pressure plate was used to analyse the forces and pressures applied through the shoes and electromyography (EMG) data was collected for eight leg muscles in order to examine the differences in muscle activity.

Reduced loading rates were found for all shoes except the wedge, which may be explained by the changed gait characteristics of the foot when the heel is raised. Other key findings were…

The pump – 12% reduction in heel impact forces
The trainer – 25% less pressure on the ball of the foot
The wedge – 5% increase in calf activation (vs. barefoot)
The flat – 8% increase in calf and 12% increase in hamstring activation
The pointed shoe – reduced pressure under 3 areas of the foot
The sandal – reduced pressure under 6 areas of the foot

The shoes were launched on the 6th December 2011 and are now available from… www.next.co.uk/women/the-fit-shoe

Quintic 4 High-Speed Camera System at the opening of RSscan Runners Service Lab

August 1st, 2011 | Podiatry, Quintic Video Software, RSscan - Footscan

Quintic 4 x High-Speed Camera System & RSscan Footscan Software Synchronise - Gait & Balance

All video files, graph and data displays in Quintic Biomechanics can be synchronised with the RSscan Footscan Pressure Plate and Force Platform data. The user can see the pressure, weight distribution, centre of pressure measurements, force Fx, Fy, Fz along with visual output of the RSscan Footscan Pressure Plate in synchronisation with the high-speed video images and kinematic data from Quintic Biomechanics. The two programs are synchronised using dual windows.

Using Quintic Biomechanics v17 to compute subtalar joint movement

June 7th, 2011 | Podiatry, Quintic Video Software

The aim of this case study is in the clinical setting to analyse the subtalar joint aixis. Quintic have been able to optimize the Quintic Biomechanics 9.03 v17 video analysis Software by integrating a novel method to measure the subtalar joint angle by using a 4 point calculation which measures the moving angle between two lines. In the case of the subtalar joint, the bisection of the calcaneum and of the tibia. The difficulty in this observation is the changing angle between the bisection and the camera, in comparison with a sagittal plane analysing video (sagittal knee or ankle flexion-extension).

Case Study
Tom is a young football player with a history of left ankle instability and ankle inversion trauma. With literature showing that the highest incidence of injury occurs during ankle inversion at the initial contact phase of gait within football players, this area needs to be thoroughly understood and analysed.

Methodology
The subjects subtalar joint is put into a neutral position and measured, reflective markers that can be automatically tracked by Quintic Biomechanics V17 video analysis software are then applied to the subject. A two marker cluster is positioned on the tibia and another two marker positioned on the posterior aspect of the calcaneum fixed on the bisection of the tibia and calcaneum with the subtalar joint in his neutral position.

The new subtalar analysis function which is only available with Quintic Biomechanics v17 video analysis software allows the clinician to accurately and quickly identify and diagnose subtalar joint problems, while also enabling detailed observation and control of an intervention/treatment in an objective way. With many anatomical joints not having a fixed axis of rotation, Quintic’s new angular analysis method is a more accurate method of analysing body motion and is more accurate than fixing an artificial axis of rotation.
